Business Overview

We are a medical technology company leading the way in the effort to successfully treat patients suffering from peripheral and coronary artery diseases, including those with arterial calcium, the most difficult disease to treat. Our employees devote every day to developing and commercializing innovative solutions that help physicians save limbs and lives when facing this difficult disease state. We are committed to clinical rigor, constant innovation and a defining drive to set the industry standard to deliver safe and effective medical devices that improve lives.

We have developed a patented orbital atherectomy technology for peripheral and coronary commercial applications. Our peripheral arterial disease systems are catheter-based platforms capable of treating a broad range of plaque types in leg arteries both above and below the knee and address many of the limitations associated with other treatment alternatives. We refer to our Stealth 360° Peripheral Orbital Atherectomy System ("OAS") ("Stealth 360") and the Diamondback 360 Peripheral OAS ("Diamondback 360 Peripheral"), collectively, in this annual report as the "PAD Systems."

As of June 30, 2014, over 155,000 of our PAD Systems have been sold to leading institutions across the United States. Sales of PAD Systems during the fiscal year ended June 30, 2014 represented 84% of revenue.

Our coronary product, the Diamondback 360 Coronary OAS ("CAD System"), is a catheter-based platform designed to facilitate stent delivery in patients with coronary artery disease ("CAD") who are acceptable candidates for PTCA or stenting due to de novo, severely calcified coronary artery lesions. The CAD System design is similar to technology used in our PAD Systems, customized specifically for the coronary application. In October 2013, we received PMA approval from the FDA to market the CAD System as a treatment for severely calcified coronary arteries. We commenced a commercial launch that same month and as of June 30, 2014, nearly 1,400 patients across the United States have benefited from the use of our coronary technology. Sales of CAD Systems during the fiscal year ended June 30, 2014 represented approximately 4% of revenue.
 
In addition to the PAD and CAD Systems, we intend to expand our product portfolio through internal product development and establishment of business relationships with other medical device companies. We offer multiple accessory products designed to complement the use of the PAD and CAD Systems, and we have an exclusive distribution agreement with Asahi-Intecc Co., Ltd. to market its peripheral guidewire line in the United States. Sales of complementary products, primarily guidewire sales, represented 12% of revenue during the fiscal year ended June 30, 2014.

Market Overview

Peripheral Artery Disease

Peripheral artery disease ("PAD") is a circulatory problem in which plaque deposits build up on the walls of the arteries, which can result in inadequate blood flow to the limbs. Arteries above the knee are generally long, straight and relatively wide compared to arteries below the knee, which tend to be shorter and branch into arteries that are progressively smaller in diameter. The most common early symptoms of PAD are pain, cramping or fatigue in the leg or hip muscles while walking. Symptoms may progress to include numbness, tingling or weakness in the leg and, in severe cases, burning or aching pain in the leg, foot or toes while resting. As PAD progresses, additional signs and symptoms occur, including cooling or color changes in the skin of the legs or feet, and wounds or sores on the legs or feet that will not heal. If left untreated, PAD may continue to progress and lead to Critical Limb Ischemia ("CLI"), a condition in which the amount of oxygenated blood being delivered to the limb is insufficient to keep the tissue alive. CLI may lead to large non-healing ulcers, infections, gangrene, limb amputation or death. Untreated CLI eventually results in an estimated 160,000 amputations per year. A study by Dr. Miguel Montero-Baker et al. concluded that a traditional antegrade recanalization attempt can fail in up to 20% of the cases (Montero-Baker et al. "Retrograde Approach for Complex Popliteal and Tibioperoneal Occlusions," J Endovasc Therapy, 2008).

There are two primary references used for estimating PAD prevalence: the patient Ankle Brachial Index ("ABI") or diabetes rates. The most recent comprehensive study, based on ABI, estimates the U.S. prevalence at 8.5 million (Allison et al, “Ethnic-Specific Prevalence of Peripheral Arterial Disease in the United States,” Circulation, 2007). Alternatively, a study by The SAGE Group, based on the diabetes method, estimates prevalence at 17.6 million in 2010 (The SAGE Group, "The Diabetes Method," 2011). An aging population, coupled with increasing incidence of diabetes and obesity, is likely to continue to increase the prevalence of PAD. In many older PAD patients, particularly those with diabetes, PAD is characterized by fibrotic (moderately hard) or calcified (extremely hard) plaque deposits that can be very challenging to treat. Although we believe the rate of PAD diagnoses is increasing, it is believed that under-diagnosis continues, due to patients failing to display symptoms or physicians misinterpreting symptoms as normal aging. Emphasis on PAD education from industry, medical associations, insurance companies and other groups, coupled with publications in medical journals and public news channels, is increasing physician and patient awareness of PAD risk factors, symptoms, and treatment options. In a Dr. Gary Mintz et al. angiography study, 1,155 native vessel target lesions in 1,117 patients were studied by intravascular ultrasound ("IVUS") and coronary angiography. The presences, magnitude, location, and distribution of IVUS calcium were analyzed and compared with the detection and classification (none/mild, moderate, and severe) by angiography. Angiography detected calcium in 440 of 1,155

2


lesions (38%): 306 (26%) moderate calcium and 134 (12%) severe calcium. The distribution of these lesions are classified as above the knee ("ATK"), at the knee or below the knee ("BTK"). According to our CONFIRM Post-Market Clinical Registry Series, which were designed to further evaluate acute parameters related to the use of the PAD Systems, 46% of the disease is ATK, 16% behind the knee and 36% BTK. As a result of additional clinical trial outcomes, new 2011 guidelines from the American College of Cardiology Foundation/American Heart Association lowered the recommended age for testing for PAD from 70 to 65, or 50 if the patient has a history of smoking or diabetes. As these guidelines are incorporated into physician practice, PAD diagnosis rates are forecasted to increase.

Physicians manage a significant portion of the PAD diagnosed population by recommending lifestyle changes, such as diet and exercise, and by prescribing prescription drugs. While medications, diet and exercise may improve blood flow, they do not treat the underlying obstruction and many patients have difficulty maintaining lifestyle changes. As a result of these challenges, many medically managed patients develop more severe symptoms that require procedural intervention.

Coronary Artery Disease

Coronary artery disease ("CAD") is a life-threatening condition and leading cause of death in men and women in the United States. CAD occurs when a fatty material called plaque builds up on the walls of arteries that supply blood to the heart. The plaque buildup causes the arteries to harden and narrow (atherosclerosis), reducing blood flow. The risk of CAD increases if a person has one or more of the following: high blood pressure, abnormal cholesterol levels, diabetes, or family history of early heart disease. According to the American Heart Association, 16.3 million people in the United States have been diagnosed with CAD, the most common form of heart disease. Heart disease claims more than 600,000 lives in the United States each year. According to estimates, significant arterial calcium is present in nearly 40% of patients undergoing a percutaneous coronary intervention ("PCI"). Significant calcium contributes to poor outcomes and higher treatment costs in coronary interventions when traditional therapies are used, including a significantly higher occurrence of death and major adverse cardiac events ("MACE").

Our PAD and CAD Systems

Our OAS represents an innovative approach to the treatment of PAD and CAD that provides physicians and patients with a procedure that addresses many of the limitations of traditional treatment alternatives. Each of the OAS utilize single-use catheters that incorporate a flexible drive shaft with an offset diamond grit coated crown. Physicians position the crown at the site of an arterial plaque-containing lesion and remove the plaque by positioning the crown to orbit against it, creating a smooth lumen, or channel, in the vessel. The OAS are designed to differentiate between hard plaque and soft, compliant arterial tissue, a concept that we refer to as “differential sanding.” The diamond grit coated crown preferentially engages and sands the harder material, but is designed not to damage more compliant parts of the artery. The Peripheral OAS also treats soft plaque, which is still harder than a normal vessel wall.

Components of the OAS

Our OAS uses a single-use, low-profile catheter that travels over our proprietary guidewires and is powered by a saline infusion. The PAD System reduces plaque on peripheral vessel walls by using a rotating, diamond-coated crown within peripheral arteries. Similarly, the CAD System uses the same method to reduce severely calcified plaque on coronary vessel walls within coronary arteries in order to facilitate stent delivery.

Catheter.  The catheter for our OAS consists of:
a control handle, which allows movement of the crown and predictable crown location;
a flexible drive shaft with a diamond grit coated offset crown, which tracks and orbits over the guidewire; and
a sheath, which covers the drive shaft and permits delivery of saline or medications to the treatment area.

ViperWire Advance Guidewire and ViperWire Advance Coronary Guidewire.  The ViperWire guidewires were designed to offer an improved ability to maneuver through tortuous, twisting blood vessels and cross challenging lesions. The OAS travels over this wire to the lesion and operate on this wire.

ViperSlide Lubricant. ViperSlide is an exclusive lubricant designed to optimize the smooth operation of the OAS.

Saline Infusion Pump.  The saline infusion pump mounts directly to the intravenous pole and bathes the OAS shaft and crown and provides an electric power supply for the operation of the catheter. The constant flow of saline reduces the risk of heat generation and improves the flush of particulates.

The mechanism of action is a function of the centrifugal force generated by the OAS as they rotate. As the speed of the crown's rotation increases, it creates centrifugal force, which increases the crown's orbit and presses the diamond grit coated offset crown against the lesion or plaque, removing a small amount of plaque with each orbit. The characteristics of the orbit and the resulting lumen size can be adjusted by modifying two variables:

Speed. An increase in speed creates a larger orbital circle, thus accommodating larger diameter vessels. Our current PAD Systems allow the user to choose between three rotational speeds. Our CAD System allows the user to choose between two rotational speeds.

Crown Characteristics.  The crowns for the OAS are designed with various weights (as determined by crown geometry and material density) and are coated with diamond grit. The PAD System crowns are available in two configurations - classic and solid. Physicians select crown sizes and configurations based on several case criteria, including reference vessel size, lesion length and degree of stenosis, stenosis morphology, and anatomy tortuosity. Physicians often use the classic crown configuration in small, more tortuous vessels or when less aggressive sanding is desired. The solid crown configuration is designed with a tapered, leading edge for frontal sanding, which can be used in tight calcified disease. The PAD Systems are available with a 1.50 millimeter and 2.00 millimeter classic crown, and 1.25 millimeter, 1.50 millimeter and 2.00 millimeter solid crown configuration. There is also a 1.25 millimeter solid micro crown available with the Diamondback 360 Peripheral device, which is designed to provide hybrid performance between the classic and solid configurations designed to treat very small arteries in the lower leg and foot. Catheter lengths are either 145 centimeters or 60 centimeters, which address procedural approach and target lesion locations both above and below the knee and now below the ankle. The shorter length catheters are designed for the retrograde pedal approach as opposed to the common femoral artery access point. The PAD Systems are versatile in that by adjusting one or more of the speeds in conjunction with crown selection, multiple lesions and vessel sizes can be treated. The crown for the CAD System is available in one configuration - 1.25 millimeter classic.

As the crown moves outward, the centrifugal force is offset by the counterforce exerted by the arterial wall. Normal arteries are compliant and have the ability to expand and contract as needed to supply blood flow. If the tissue is compliant, it flexes away, rather than generating an opposing force that would allow the OAS to engage and sand the wall. Diseased tissue provides resistance and is able to generate an opposing force that allows the OAS to engage and sand the plaque. The sanded plaque is broken down into particles generally smaller than circulating red blood cells that are washed away downstream with the patient's natural blood flow. PAD System testing performed in carbon blocks, animal and cadaver models showed:

greater than 93% of particles were smaller than a red blood cell, and
greater than 99% of particles were smaller than the lumen of the capillaries (which provide the connection between the arterial and venous system).

The small particle size minimizes the risk of vascular bed overload, or a saturation of the peripheral or coronary vessels with large particles, which may cause slow or reduced blood flow. The small size of the particles allow them to be managed by the body's natural cleansing of the blood, including various types of white blood cells that eliminate worn-out cells and other debris in the bloodstream.

We believe the OAS offer the following key benefits:

Strong Safety Profile

Differential Sanding Reduces Risk of Adverse Events. The OAS are designed to differentiate between hard plaque and soft compliant arterial tissue. Arteries are composed of three tissue layers. The diamond grit coated offset crown at the working end of the devices engages and removes plaque from the artery wall with minimal likelihood of penetrating or damaging the fragile, inner layer of the arterial wall because soft, compliant tissue flexes away from the crown. Furthermore, the OAS have rarely penetrated the middle or outer layers of the artery's wall. The Diamondback 360 Peripheral's perforation rate was 1.6% during our pivotal OASIS trial. Analysis by an independent pathology laboratory of more than 434 consecutive cross sections of porcine arteries treated with the Diamondback 360 Peripheral revealed there was minimal to no damage, on average, to the middle layer, which is typically associated with restenosis. Similarly, the CAD System perforation rate was 1.8% during our pivotal ORBIT II trial. Analysis by an independent pathology laboratory of more than 443 patients enrolled in the ORBIT II Trial revealed 4 patients had a perforation after the OAS treatment and another 4 patients had a perforation after stent deployment, for a total of 8 perforations reported.


4


Eliminates Need for Distal Protection. The small size of the particles produced during sanding avoids the need for plaque collection reservoirs on the catheter and reduces the need for ancillary distal protection devices, commonly used with directional cutting atherectomy devices, and also significantly reduces the risk that larger pieces of removed plaque will block blood flow downstream.

Allows Continuous Blood Flow During Procedure. The OAS allow for continuous blood flow during the procedure, except when initially used in chronic total occlusions. Other devices may restrict blood flow due to the size of the catheter required or the use of distal protection devices, which could result in complications such as excessive heat and tissue damage.

Proven Efficacy
        
Efficacy Demonstrated for Both PAD and CAD Systems. Our pivotal OASIS clinical trial was a prospective 20-center study that involved 124 patients with 201 lesions treated by the Diamondback 360 PAD System. Performance targets were established cooperatively with the FDA before the trial began. Despite 55% of the lesions consisting of calcified plaque, the Diamondback 360 Peripheral successfully met the FDA's study endpoints. Because the Predator 360 and Stealth 360 mechanism of action is identical to that of the Diamondback 360 Peripheral, no additional efficacy trials were required by the FDA for 510(k) clearance of either PAD System. For the CAD System, our ORBIT II coronary OAS trial was designed to evaluate the safety and efficacy of OAS in treating severely calcified coronary lesions. The trial met both the primary safety and efficacy endpoints by significant margins. Preparation of severely calcified plaque with the OAS not only helped facilitate stent delivery, but also improved both acute and 30-day clinical outcomes compared with the outcomes of historic control subjects in this difficult-to-treat patient population. The pre-procedure mean minimal lumen diameter of 0.5 mm increased to 2.9 mm after the procedure. The primary safety endpoint was 89.6% freedom from 30-day MACE compared with the performance goal of 83%. The primary efficacy endpoint (residual stenosis <50% post-stent without in-hospital major adverse cardiac events) was 88.9% compared with the performance goal of 82%. Stent delivery was successful in 97.7% of cases; <50% stenosis was observed in 98.6% of subjects. Low rates of in-hospital Q-wave myocardial infarction (0.7%), cardiac death (0.2%), and target vessel revascularization (0.7%) were reported.

Treats Difficult, Fibrotic and Calcified Lesions. The OAS enable physicians to remove plaque from long, fibrotic, calcified or bifurcated lesions, as well as lesions with softer plaque, in peripheral arteries both above and below the knee.

Orbital Motion Improves Lesion Compliance. The orbiting action of the OAS removes the hard plaque in the artery by sanding. As the crown sands away the plaque, the lumen of the artery is opened and the vessel wall becomes more compliant. The orbital motion and speed of the crown increases, thus allowing for continuous removal of plaque as the opening of the lumen increases during the operation of the devices.

Differential Sanding Creates Smooth Lumens. The differential sanding of the OAS creates a smooth surface lumen, or channel, inside the vessel. We believe that the smooth lumens created by the device increase the velocity of blood flow and decrease the resistance to blood flow, which may decrease the potential for restenosis, or renarrowing of the arteries.

Ease of Use
        
Utilizes Familiar Techniques. Physicians using the OAS employ techniques similar to those used in angioplasty, which are familiar to interventional cardiologists, vascular surgeons and interventional radiologists who are trained in endovascular techniques. The devices' simple user interfaces require minimal additional training.

Single Insertion to Complete Treatment. The orbital technology and differential sanding process of the OAS allows for a single insertion to treat lesions, in most cases. Because the particles of plaque sanded away are of such small sizes, the OASs do not require a collection reservoir that needs to be repeatedly emptied or cleaned during the procedure, or add time and cost to the procedure. Rather, the OAS allow for multiple passes of the device over the lesion until plaque is removed and a smooth lumen is created.

Multiple Applications
        
The unique OAS mechanism of action used in both the PAD and CAD Systems can be used to treat multiple anatomic locations.

Below-the-Knee and Behind-the-Knee Peripheral Artery Disease.  Arteries below and behind the knee have small diameters and may be diffusely diseased, calcified or both, and reaching and treating these small vessels requires a small form factor which eliminates several competitive devices from being an option. Behind-the-knee lesions also present challenges if a stent is used because stents frequently fracture due to the forces exerted on the vessels when the knee bends or flexes. The PAD Systems are effective in both soft and calcified vessels. This was demonstrated in the Orbital Atherectomy System for the Treatment of Peripheral Vascular Stenosis ("OASIS") trial, where 94.5% of lesions treated with the Diamondback 360 Peripheral were behind or below the knee. The recently introduced Diamondback 360 60cm Peripheral OAS offers a shorter shaft length and a smaller profile and a more flexible shaft than their predecessors for improved ease of use. This product uses a 4 French catheter which enables physicians to access lesions below-the-knee using retrograde access (access through the ankle or foot).

Above-the-Knee Peripheral Artery Disease.  Arteries above the knee are typically longer, straighter and wider than below-the-knee vessels. Plaque in these arteries may also be diffuse, fibrotic and calcific. Physicians often use higher speeds or larger crown sizes of our products to treat lesions above the knee.    

Coronary Artery Disease. CAD occurs when a fatty material called plaque builds up on the walls of arteries that supply blood to the heart. The plaque buildup causes the arteries to harden and narrow (atherosclerosis), reducing blood flow.

Cost and Time Efficient Procedure
        
Short Procedure Time. The OAS has a short treatment time, typically less than two minutes.

Single Crown Can Create Various Lumen Sizes Limiting Hospital Inventory Costs. The OAS orbital mechanism of action allow one device to create various diameter lumens inside the artery. Adjusting the rotational speed of the crown changes the orbit to create the desired lumen diameter, thereby potentially avoiding the need to use multiple catheters of different sizes to treat multiple lesions.

Single Insertion May Reduce Procedural Time. Since the physician does not need to insert and remove multiple catheters or clean a plaque collection reservoir to complete the procedure, there is a potential for decreased procedure time.

Our OAS Strategy

Our goal is to be the leading provider of minimally invasive solutions for the treatment of peripheral and coronary disease. The key elements of our strategy include:
        
Drive Adoption through Our Direct Sales Organization and Key Opinion Leaders. We expect to continue to drive adoption of the OAS through our direct sales force in both hospital and office-based lab settings, which targets interventional cardiologists, vascular surgeons, and interventional radiologists. As a key element of our strategy, we focus on educating and training physicians on the OAS through our direct sales force and through seminars where physician industry leaders discuss case studies and treatment techniques using the devices.

Collect Additional Clinical Evidence on Benefits of the OAS. Physicians are increasingly requesting clinical study evidence to allow them to make the best treatment decisions to achieve the best possible short-term and long-term outcomes for their patients. We are focused on collecting and using clinical evidence to demonstrate the advantages of the OAS and drive physician acceptance.

Enhance OAS and Expand Product Portfolio within the Market for Treatment of Peripheral and Coronary Arteries. In addition to enhancing the OAS, we have expanded our product portfolio. We offer multiple accessory devices designed to complement the use of the OAS. We are continuing to evaluate internal product development to further expand our portfolio of PAD and CAD treatment solutions.

Expand Internationally. With CE Mark expected for both the PAD and CAD Systems in fiscal 2015 and the anticipated coronary approval for the next generation coronary OAS device in Japan during the 2016-2017 timeframe, we are evaluating a variety of options for international expansion to maximize the coronary and peripheral market opportunities. Sales channels will be based on specific country dynamics. As a result, distributors - including potential strategic partners - and direct sales channels are being evaluated.

Pursue Strategic Acquisitions and Partnerships.  In August 2009, we signed an exclusive distribution agreement with Asahi to market two peripheral guidewire lines in the United States. In August 2011, we signed an amendment to expand the agreement to include three additional peripheral guidewires. The product portfolio now includes the Treasure Floppy and Regalia and three specialty wires: Astato 20, Astato 30, and Treasure 12. In June 2013, we signed an amendment to extend the exclusive guidewire agreement two more years.

Healthcare Policy and Reimbursements. Our healthcare policy initiatives are targeted at raising awareness with public and private payors along with key medical societies on the clinical and economic issues associated with peripheral and coronary arterial calcium. Working with payors and medical societies over time will sustain coverage for our OAS technology and ensure practice guidelines include appropriate treatment options for patients with arterial calcium.
    
In addition to adding to our product portfolio through internal development efforts, we intend to continue to explore the acquisition of other product lines, technologies or companies that may leverage our sales force or complement our strategic objectives. We plan to continue to evaluate distribution agreements, licensing transactions, and other strategic partnerships.

Clinical Studies Summary

We are committed to providing relevant clinical evidence that enables physicians to select and utilize the best treatment options for their patients. Our clinical studies incorporate rigorous long-term clinical and healthcare economic data that are critical to improve long-term patient care and ongoing healthcare changes. We have conducted 14 clinical studies to demonstrate the safety and efficacy of the PAD Systems. A total of 3,777 patients were enrolled in various studies including our PAD I and PAD II pilot studies, OASIS pivotal study, CONFIRM post market registries, the CALCIUM 360°, COMPLIANCE 360° and CLARITY post market, randomized feasibility studies, the TRUTH post market study, and multiple physician sponsored studies. The results of these studies consistently demonstrated that the PAD Systems provide predictable, repeatable and durable results that differentiate themselves from other PAD treatments. The following are PAD clinical studies completed or in process during fiscal 2014:

OASIS. In September 2005 our IDE was approved to begin OASIS, our pivotal U.S. study. OASIS was a 124-patient, 20-center, prospective study that began enrollment in January 2006. The primary efficacy study endpoint was absolute plaque reduction of the target lesions from baseline to immediately post-procedure. The primary safety endpoint was the cumulative incidence of Serious Adverse Events ("SAE") at 30 days. In the OASIS study, 94.5% of lesions treated were behind or below the knee, an area where lesions have traditionally gone untreated until they require bypass surgery or amputation. Of the lesions treated in OASIS, 55% were comprised of calcified plaque, which presents a challenge to proper expansion and apposition of balloons and stents, and 48% were diffuse, or greater than 3 cm in length. Results of OASIS exceeded FDA pre-specified acceptance criteria with an overall plaque reductions of 59.4%, freedom from SAE of 95.2% device related and 90.3% overall and freedom from TLR of 97.6%.

TRUTH. A prospective, single-arm (non-randomized), post-market study that used IVUS imaging and angiography to assess procedural outcomes in patients who have symptomatic peripheral artery disease who are treated with the Sponsor's OAS and adjunctive balloon angioplasty. An independent IVUS Core Lab was used to provide adjudicated analyses for IVUS outcomes.

CLARITY. A pilot study designed to identify the clinically appropriate endpoint(s) of a larger, statistically powered pivotal trial for treatment of patients with CLI.

LIBERTY 360°. We are currently enrolling up to 1,200 patients in our LIBERTY 360° clinical PAD study, which is a prospective, observational, multi-center clinical study to evaluate acute and long term clinical, quality of life and economic outcomes of endovascular device intervention in patients with distal outflow peripheral arterial disease. This study is designed with unique endpoints to demonstrate how the PAD Systems provide effective long-term clinical and economic outcomes compared to other treatment alternatives.

CAD, the most common form of heart disease, continues to grow significantly worldwide. Performing PCI on calcified lesions can lead to MACE rates as high as 24% at 30 days, stent malposition, and a number of procedural complications. Despite being a relatively common problem, there have been no FDA Investigational Device Exemption ("IDE") premarket approval ("PMA") trials studying only patients with severe coronary calcification, before our ORBIT I and ORBIT II trials.

ORBIT I. The ORBIT I feasibility study evaluated performance of the Diamondback 360° for the treatment of de novo calcified coronary lesions. The ORBIT I study completed in India in 2009 enrolled 50 patients. The endpoints were measured by device performance, MACE rate, and TLR at six months. Device performance success was 98%. The freedom from MACE at 30 days and at 6 months was 94% and 92% respectively. The 30-day and 6-month freedom from TLR was 98%. A single center follow-up of 33 patients demonstrated a freedom MACE of 79% at five year follow up as presented at Society for Cardiovascular Angiography and Interventions in May 2014.

ORBIT II. In 2010, we began the ORBIT II pivotal study in the U.S, evaluating the use of the CAD System in treating coronary arteries and in October 2013, we received PMA from the FDA. One year ORBIT II study revascularization rate was significantly lower compared to historic controls with a freedom from cardiac death of 97% in this difficult to treat population and freedom from target lesion revascularization ("TLR") of 95%. We continue to expand our coronary clinical data with long term clinical and economic data demonstrating positive results for patients treated with the CAD System. ORBIT II one year patient follow-up was completed in fiscal 2014. The results were presented at Cardiovascular Research Technologies conference as a Late Breaking Clinical Trial in February 2014. Results demonstrated a freedom from TLR rate of 95.3% and freedom from MACE rate of 83.6% in this difficult-to-treat patient population of severe calcified coronary lesions. An economic analysis was also completed that demonstrated a reduction in average length of stay of 2.44 days compared to the MedPAR average length of stay with a 414.4 code of 4.24 days. The average savings was $4,294 per patient, based on the ORBIT II inpatient economic data of the index procedure costs and the 30-day procedure related readmission costs. A subsequent economic analysis of ORBIT II economic data using both outpatient and inpatient data resulted in an average savings of $3,200 per patient.

Ongoing Clinical Studies in Fiscal 2014

MACE. The MACE study is a post market coronary multi-center, prospective study to evaluate major adverse coronary events along with TLR and perforations in the treatment of moderate to severely calcified coronary lesions. This registry will include commercially available devices for revascularization involving stent deployment in de novo coronary lesions. The data from this registry will demonstrate the rate of calcification in the “real-world” setting as well as examine health care resource utilization. Enrollment in the 500 patient study has begun at up to 50 U.S. sites. These patients will be followed up to three years.

COAST. This is a prospective, single-arm, multi-center, global study designed to evaluate performance of the Diamondback 360 Coronary Micro Crown OAS. This study expands on the already effective current Diamondback 360 Coronary OAS to evaluate the next generation coronary OAS coronary device globally. We have begun enrolling up to 100 subjects at up to 15 U.S. sites and five sites in Japan. Minimum enrollment is 50 patients in the U.S. and 25 in Japan.

Sales and Marketing

We market and sell our products through a direct sales force in the United States. Revenues for the PAD and CAD Systems for fiscal 2014, fiscal 2013 and fiscal 2012 were $120.4 million, $91.2 million and $73.0 million, respectively. We have targeted sales and marketing efforts to interventional cardiologists, vascular surgeons and interventional radiologists with experience using similar catheter-based procedures, such as angioplasty, stenting, and cutting or laser atherectomy. Peer-to-peer education is a key element of our sales strategy.

We target our marketing efforts to practitioners through physician education, medical conferences, seminars, peer-reviewed journals and marketing materials. Our sales and marketing program focuses on:

educating physicians regarding the proper use and application of the OAS;
clinical results showing safety and efficacy of products;
educating physicians on the prevalence and complications of calcium in PAD and CAD; and
developing relationships with key opinion leaders.

We are not currently marketing our products internationally; however, we continue to evaluate international opportunities.

Research and Development

Our research and development efforts are focused in the development of products to penetrate our three key target markets: below and behind-the-knee, above-the-knee, and coronary vessels. In additional to the key target markets, we also focus on alternative access sites. Research and development projects include the development of new products, enhancement of existing products, and PAD and CAD clinical trials. Research and development expenses for fiscal 2014, fiscal 2013 and fiscal 2012 were $21.1 million, $15.2 million and $11.4 million, respectively.

Manufacturing
 
We use internally-manufactured and externally-sourced components to manufacture the OAS. Most of the externally-sourced components are available from multiple suppliers; however, certain key components, including the diamond grit coated crown, and our ViperSlide Lubricant are single sourced. We have strategies and arrangements in place for procuring our key components from alternative suppliers in the event that one or more of our single source suppliers were to discontinue supplying us with a key component. We assemble the shaft, crown and handle components on-site, and test, pack, seal and label the finished assembly before sending the packaged product to a contract sterilization facility. Upon return from the sterilizer, the product is held in inventory prior to shipping to our customers.
 
Our manufacturing facility in Minnesota, including the shaft manufacturing and the controlled-environment assembly areas, is equipped to accommodate approximately 30,000 devices per shift annually. It also has storage capacity for approximately 8,000 devices and 100 saline infusion pumps.

Our Pearland, Texas facility is 46,000 square feet and includes a custom-built clean room and production space for future expansion of value-add processes, including machining and electronics assembly. The facility, when it becomes fully staffed and equipped, will have the capacity to produce approximately 75,000 devices per shift annually. This facility has finished goods storage capacity for greater than 15,000 OAS devices and other accessory products and over 500 Stealth 360 and Diamondback 360 saline infusion pumps.

We are underway with the construction of a new, 125,000-square-foot, two-story building in Minnesota that will have space for more than 500 employees and contain dedicated research and development, training and education, and manufacturing facilities. The operations-dedicated space will expand our production and inventory capacity significantly. Depending on staffing scale, the new facility will have the capacity to produce in excess of 75,000 devices per shift annually. The finished goods storage capacity for nearly 20,000 devices and more than 500 saline infusion pumps, as well as other accessory products. Occupancy of the new facility is expected to commence in March 2015, with full transfer of operations by December 2015. We believe that our current facilities, including the new corporate headquarters, are substantially adequate for our current and anticipated future needs for the foreseeable future.

We are registered with the FDA as a medical device manufacturer. We have opted to maintain quality assurance and quality management certifications to enable us to market our products in the member states of the European Union, the European Free Trade Association and countries that have entered into Mutual Recognition Agreements with the European Union. We are ISO 13485:2003 certified, and our renewal is due by December 2015. Under these registrations, our plants are audited by FDA and our Notified Body for the EU CE mark.

Third-Party Reimbursement and Pricing
 
Third-party payors, including private insurers, and government insurance programs, such as Medicare and Medicaid, pay for a significant portion of patient care provided in the United States. The single largest payor in the United States is the Medicare program, a federal governmental health insurance program administered by the Centers for Medicare and Medicaid Services ("CMS"). Medicare covers certain medical care expenses for eligible elderly and disabled individuals, including a large percentage of the population with PAD and CAD who could be treated with the OAS. In addition, private insurers often follow the coverage and reimbursement policies of Medicare. Consequently, Medicare's coverage and reimbursement policies are important to our operations.

CMS has established Medicare reimbursement codes describing atherectomy products and procedures using atherectomy products. We believe that physicians and hospitals that treat PAD and CAD with the respective OAS will generally be eligible to receive reimbursement from Medicare, as well as private insurers, for the cost of the single-use catheter and the physician's services.

Competition
 
The medical device industry is highly competitive, subject to rapid change and significantly affected by new product introductions and other activities of industry participants. The OAS compete with a variety of other products or devices for the treatment of vascular disease, including stents, balloon angioplasty catheters and atherectomy catheters, as well as products used in vascular surgery. Large competitors in the stent and balloon angioplasty market segments include Abbott Laboratories, Boston Scientific, Cook Medical, Johnson & Johnson, BARD, and Medtronic. We also compete against manufacturers of atherectomy catheters including, among others, Covidien, Spectranetics, Boston Scientific and Volcano, as well as other manufacturers that may enter the market due to the increasing demand for treatment of vascular disease. Other competitors include pharmaceutical companies that manufacture drugs for the treatment of mild to moderate PAD and CAD and companies that provide products used by surgeons in peripheral and coronary bypass procedures. We are not aware of any competing catheter systems either currently on the market or in development that also use an orbital motion to create lumens larger than the catheter itself.

Because of the size of the peripheral opportunities, competitors and potential competitors have historically dedicated significant resources to aggressively promote their products. We believe that the PAD and CAD Systems compete primarily on the basis of:

safety and efficacy;
predictable clinical performance;
availability of clinical data;
ease of use;
economic benefit;
key opinion leader support and customer base;
customer service and support; and
adequate third-party reimbursement.

Patents and Intellectual Property
 
We rely on a combination of patent, copyright and other intellectual property laws, trade secrets, nondisclosure agreements and other measures to protect our proprietary rights. As of July 29, 2014, we held 42 issued U.S. patents and have 46 U.S. patent applications pending, as well as 148 issued or granted foreign patents and 133 foreign patent applications, each of which corresponds to aspects of our U.S. patents and applications. Our issued U.S. patents expire between 2014 and 2032, and our most important patents, U.S. Patent No. 6,494,890 and two key design patents covering our eccentric abrasive crown technology are due to expire on June 1, 2019, February 16, 2024 and December 29, 2023, respectively. In addition, we have many additional patents relating to our core technology currently pending in the USPTO which will extend our key covered subject matter and coverage dates significantly. Our issued patents and patent applications relate primarily to the design and operation of interventional atherectomy devices, including the PAD Systems. These patents and applications include claims covering key aspects of orbital atherectomy devices, including the design, manufacture and therapeutic use of certain atherectomy abrasive heads, drive shafts, control systems, handles and couplings. As we continue to research and develop our atherectomy technology, we intend to file additional U.S. and foreign patent applications related to the design, manufacture and therapeutic uses of atherectomy devices. In addition, we hold 19 registered U.S. trademarks, 15 registered marks in the Madrid Protocol with protection granted within at least one of Australia, Europe, China, Japan and Mexico, six registered marks in Europe, five registered marks in Canada, five registered marks in Mexico, and nine registered marks in Hong Kong. We hold five trademark applications pending in the U.S, 12 trademark applications pending in Canada and 16 trademark applications pending in India.
 
We also rely on trade secrets, technical know-how and continuing innovation to develop and maintain our competitive position. We seek to protect our proprietary information and other intellectual property by requiring our employees, consultants, contractors, outside scientific collaborators and other advisors to execute non-disclosure and assignment of invention agreements on commencement of their employment or engagement. Agreements with our employees also forbid them from bringing the proprietary rights of third parties to us. We also require confidentiality or material transfer agreements from third parties that receive our confidential data or materials.

Government Regulation of Medical Devices

Governmental authorities in the U.S. at the federal, state and local levels and in other countries extensively regulate, among other things, the development, testing, manufacture, labeling, promotion, advertising, distribution, marketing and export and import of medical devices such as the PAD and CAD Systems.

10


Failure to obtain approval to market our products under development and to meet the ongoing requirements of these regulatory authorities could prevent us from marketing and continuing to market our products.

United States

The Federal Food, Drug, and Cosmetic Act ("FDCA") and the FDA’s implementing regulations govern medical device design and development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, sales and distribution, export and import, and post market surveillance. Medical devices and their manufacturers are also subject to inspection by the FDA. The FDCA, supplemented by other federal and state laws, also provides civil and criminal penalties for violations of its provisions. We manufacture and market medical devices that are regulated by the FDA, comparable state agencies and regulatory bodies in other countries.

Unless an exemption applies, each medical device we wish to commercially distribute in the U.S. will require marketing authorization from the FDA prior to distribution. The two primary types of FDA marketing authorization are premarket notification (also called 510(k) clearance) and premarket approval (also called PMA approval). The type of marketing authorization applicable to a device - 510(k) clearance or PMA approval - is generally linked to classification of the device. The FDA classifies medical devices into one of three classes (Class I, II or III) based on the degree of risk FDA determines to be associated with a device and the extent of control deemed necessary to ensure the device’s safety and effectiveness. Devices requiring fewer controls because they are deemed to pose lower risk are placed in Class I or II. Class I devices are deemed to pose the least risk and are subject only to general controls applicable to all devices, such as requirements for device labeling, premarket notification, and adherence to the FDA’s current good manufacturing practice requirements, as reflected in its Quality System Regulation ("QSR"). Class II devices are intermediate risk devices that are subject to general controls and may also be subject to special controls such as performance standards, product-specific guidance documents, special labeling requirements, patient registries or post market surveillance. Class III devices are those for which insufficient information exists to assure safety and effectiveness solely through general or special controls, and include life-sustaining, life-supporting or implantable devices, and devices not “substantially equivalent” to a device that is already legally marketed.
Most Class I devices and some Class II devices are exempted by regulation from the 510(k) clearance requirement and can be marketed without prior authorization from FDA. Class I and Class II devices that have not been so exempted are eligible for marketing through the 510(k) clearance pathway. By contrast, devices placed in Class III generally require PMA approval prior to commercial marketing. The PMA approval process is generally more stringent, time-consuming and expensive than the 510(k) clearance process.

510(k) Clearance.    To obtain 510(k) clearance for a medical device, an applicant must submit a premarket notification to the FDA demonstrating that the device is “substantially equivalent” to a predicate device legally marketed in the United States. A device is substantially equivalent if, with respect to the predicate device, it has the same intended use and has either (i) the same technological characteristics or (ii) different technological characteristics and the information submitted demonstrates that the device is as safe and effective as a legally marketed device and does not raise different questions of safety or effectiveness. A showing of substantial equivalence sometimes, but not always, requires clinical data. Generally, the 510(k) clearance process can exceed 90 days and may extend to a year or more.

After a device has received 510(k) clearance for a specific intended use, any modification that could significantly affect its safety or effectiveness, such as a significant change in the design, materials, method of manufacture or intended use, will require a new 510(k) clearance or PMA approval (if the device as modified is not substantially equivalent to a legally marketed predicate device). The determination as to whether new authorization is needed is initially left to the manufacturer; however, the FDA may review this determination to evaluate the regulatory status of the modified product at any time and may require the manufacturer to cease marketing the modified device until 510(k) clearance or PMA approval is obtained. The manufacturer may also be subject to significant regulatory fines or penalties.

We received 510(k) clearance for use of the Diamondback 360 Peripheral as a therapy in patients with PAD in the United States on August 22, 2007. We received additional 510(k) clearances for the control unit used with the Diamondback 360 Peripheral on October 25, 2007 and for the solid crown version of the Diamondback 360 Peripheral on November 9, 2007. We were granted 510(k) clearance of the Predator 360 in March 2009 and Stealth 360 in March 2011. We received 510(k) clearance of the Diamondback 360 60cm Peripheral OAS in March 2014.

Premarket Approval.    A PMA application requires the payment of significant user fees and must be supported by valid scientific evidence, which typically requires extensive data, including technical, preclinical, clinical and manufacturing data, to demonstrate to the FDA’s satisfaction the safety and efficacy of the device. A PMA application must also include a complete description of the device and its components, a detailed description of the methods, facilities and controls used to manufacture the device, and proposed labeling. After a PMA application is submitted and found to be sufficiently complete, the FDA begins

11


an in-depth review of the submitted information. During this review period, the FDA may request additional information or clarification of information already provided. Also during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. In addition, the FDA will conduct a pre-approval inspection of the manufacturing facilities to ensure compliance with the FDA’s QSR which requires manufacturers to follow design, testing, control, documentation and other quality assurance procedures.

FDA review of a PMA application is required by statute to take no longer than 180 days, although the process typically takes significantly longer, and may require several years to complete. The FDA can delay, limit or deny approval of a PMA application for many reasons, including:

the systems may not be safe or effective to the FDA’s satisfaction;
the data from preclinical studies and clinical trials may be insufficient to support approval;
the manufacturing process or facilities used may not meet applicable requirements; and
changes in FDA approval policies or adoption of new regulations may require additional data.

If the FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an approvable letter, which usually contains a number of conditions that must be met in order to secure final approval of the PMA. When and if those conditions have been fulfilled to the satisfaction of the FDA, the agency will issue a PMA approval letter authorizing commercial marketing of the device for certain indications. If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. The FDA may also determine that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the trials are conducted and then the data submitted in an amendment to the PMA. Even if a PMA application is approved, the FDA may approve the device with an indication that is narrower or more limited than originally sought. The agency can also impose restrictions on the sale, distribution or use of the device as a condition of approval, or impose post approval requirements such as continuing evaluation and periodic reporting on the safety, efficacy and reliability of the device for its intended use.

New PMA applications or PMA supplements may be required for modifications to the manufacturing process, labeling, device specifications, materials or design of a device that is approved through the PMA process. PMA approval supplements often require submission of the same type of information as an initial PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA application and may not require as extensive clinical data or the convening of an advisory panel.

The FDA granted unconditional IDE approval in April 2010 to begin the ORBIT II coronary trial in the United States. This pivotal trial was set up in two phases; Phase I allowed us to enroll up to 100 patients at as many as 50 U.S. sites, Phase II allowed us to expand the trial to the full complement of 429 patients. In May 2011, we received approval from the FDA to complete enrollment of 429 patients in our ORBIT II clinical trial for a coronary application for the Diamondback 360, which followed the FDA’s review of data from the first 50 cases in the ORBIT II trial. In July 2012, we received approval from the FDA to include the new electric coronary device (similar to Stealth 360 technology used in PAD and customized specifically for the coronary application), which improves ease of use. The FDA required 100 enrollments with the new electric coronary device and would have allowed up to 50 additional patients in the trial, as needed, to achieve that enrollment level. A total of 443 patients were enrolled in the trial. In March 2013, we completed submission of our PMA application to the FDA for our orbital atherectomy system to treat calcified coronary arteries. In October 2013, we received PMA approval from the FDA to market the Diamondback 360 Coronary OAS as a treatment for severely calcified coronary arteries. We commenced a controlled commercial launch of the CAD System following receipt of PMA approval.
 
Clinical Trials.  Clinical trials are almost always required to support a PMA application and are sometimes required for a 510(k) clearance. These trials generally require submission of an application for an IDE to the FDA. The IDE application must be supported by appropriate data, such as animal and laboratory testing results, showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. The IDE application must be approved in advance by the FDA for a specified number of patients, unless the product is deemed a non- significant risk device and eligible for more abbreviated IDE requirements. Generally, clinical trials for a significant risk device may begin once the IDE application is approved by the FDA and the study protocol and informed consent are approved by appropriate institutional review boards at the clinical trial sites.
FDA approval of an IDE allows clinical testing to go forward but does not bind the FDA to accept the results of the trial as sufficient to prove the product’s safety and efficacy, even if the trial meets its intended success criteria. With certain exceptions, changes made to an investigational plan after an IDE is approved must be submitted in an IDE supplement and approved by FDA (and by governing institutional review boards when appropriate) prior to implementation.


12


All clinical trials must be conducted in accordance with regulations and requirements collectively known as good clinical practice. Good clinical practices include the FDA’s IDE regulations, which describe the conduct of clinical trials with medical devices, including the recordkeeping, reporting and monitoring responsibilities of sponsors and investigators, and labeling of investigation devices. They also prohibit promotion, test marketing or commercialization of an investigational device and any representation that such a device is safe or effective for the purposes being investigated. Good clinical practices also include the FDA’s regulations for institutional review board approval and for protection of human subjects (such as informed consent), as well as disclosure of financial interests by clinical investigators.

Required records and reports are subject to inspection by the FDA. The results of clinical testing may be unfavorable or, even if the intended safety and efficacy success criteria are achieved, may not be considered sufficient for the FDA to grant approval or clearance of a product. The commencement or completion of any clinical trials may be delayed or halted, or be inadequate to support approval of a PMA application or clearance of a premarket notification for numerous reasons, including, but not limited to, the following:

the FDA or other regulatory authorities do not approve a clinical trial protocol or a clinical trial (or a change to a previously approved protocol or trial that requires approval), or place a clinical trial on hold;
patients do not enroll in clinical trials or follow up at the rate expected;
patients do not comply with trial protocols or experience greater than expected adverse side effects;
institutional review boards and third-party clinical investigators may delay or reject the trial protocol or changes to the trial protocol;
third-party clinical investigators decline to participate in a trial or do not perform a trial on the anticipated schedule or consistent with the clinical trial protocol, investigator agreements, good clinical practices or other FDA requirements;
third-party organizations do not perform data collection and analysis in a timely or accurate manner;
regulatory inspections of the clinical trials or manufacturing facilities, which may, among other things, require corrective action or suspension or termination of the clinical trials;
changes in governmental regulations or administrative actions;
the interim or final results of the clinical trial are inconclusive or unfavorable as to safety or efficacy; and
the FDA concludes that the trial design is inadequate to demonstrate safety and efficacy.

Continuing Regulation.    After a device is cleared or approved for use and placed in commercial distribution, numerous regulatory requirements continue to apply. These include:

establishment registration and device listing upon the commencement of manufacturing;
the QSR, which requires manufacturers, including third-party manufacturers, to follow design, testing, control, documentation and other quality assurance procedures during medical device design and manufacturing processes;
labeling regulations, which prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling and promotional activities;
medical device reporting regulations, which require that manufacturers report to the FDA if a device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if malfunctions were to recur;
corrections and removal reporting regulations, which require that manufacturers report to the FDA field corrections; and
product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA caused by the device that may present a risk to health.

In addition, the FDA may require a company to conduct post market surveillance studies or order it to establish and maintain a system for tracking its products through the chain of distribution to the patient level.

Failure to comply with applicable regulatory requirements, including those applicable to the conduct of clinical trials, can result in enforcement action by the FDA, which may lead to any of the following sanctions:

warning letters or untitled letters;
fines, injunctions and civil penalties;
product recall or seizure;
unanticipated expenditures;
delays in clearing or approving or refusal to clear or approve products;
withdrawal or suspension of FDA approval;
orders for physician notification or device repair, replacement or refund;

13


operating restrictions, partial suspension or total shutdown of production or clinical trials; and
criminal prosecution.

We and our contract manufacturers, specification developers and suppliers are also required to manufacture our products in compliance with current Good Manufacturing Practice requirements set forth in the QSR.

The QSR requires a quality system for the design, manufacture, packaging, labeling, storage, installation and servicing of marketed devices, and includes extensive requirements with respect to quality management and organization, device design, buildings, equipment, purchase and handling of components, production and process controls, packaging and labeling controls, device evaluation, distribution, installation, complaint handling, servicing and record keeping. The FDA enforces the QSR through periodic announced and unannounced inspections that may include the manufacturing facilities of subcontractors. If the FDA believes that we or any of our contract manufacturers or regulated suppliers is not in compliance with these requirements, it can shut down our manufacturing operations, require recall of our products, refuse to clear or approve new marketing applications, institute legal proceedings to detain or seize products, enjoin future violations or assess civil and criminal penalties against us or our officers or other employees. Any such action by the FDA would have a material adverse effect on our business.

Fraud and Abuse

Our operations will be directly, or indirectly through our customers, subject to various state and federal fraud and abuse laws, including, without limitation, the FDCA, federal Anti-Kickback Statute and False Claims Act. These laws may impact, among other things, our proposed sales, marketing, and education programs. In addition, these laws require us to screen individuals and other companies, suppliers and vendors in order to ensure that they are not “debarred” by the federal government and therefore prohibited from doing business in the healthcare industry.

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or service, for which payment may be made under a federal healthcare program such as the Medicare and Medicaid programs. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Many states have also adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs.

The federal False Claims Act prohibits persons from knowingly filing or causing to be filed a false claim to, or the knowing use of false statements to obtain payment from, the federal government. Various states have also enacted laws modeled after the federal False Claims Act.

In addition to the laws described above, the Health Insurance Portability and Accountability Act of 1996 created two new federal crimes: healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services.

On May 8, 2014, we received a letter from the U.S. Attorney’s Office for the Western District of North Carolina stating that it is investigating the Company to determine whether we had violated the False Claims Act, resulting in the submission of false claims to federal and state health care programs, including Medicare and Medicaid. The letter enclosed a Civil Investigative Demand (“CID”) for written interrogatories and document requests. We maintain rigorous policies and procedures to promote compliance with the False Claims Act and other regulatory requirements, and are working with the U.S. Attorney’s Office to promptly respond to the CID. However, we cannot predict when the investigation will be resolved, the outcome of this investigation or its potential impact on the Company.

The federal Physician Payments Sunshine Act, or the Sunshine Act, was enacted by Congress in 2010 as part of the comprehensive health care reform legislation, and the implementing Open Payment regulations, released in February 2013, require persons to begin collecting certain data on payments and other transfers of value to physicians and teaching hospitals beginning in August 2013 for public reporting by the end of June 2014. We submitted all required information by the reporting

deadline. It is widely anticipated that public reporting under the Sunshine Act and implementing Open Payment regulations will result in increased scrutiny of the financial relationships between industry, physicians and teaching hospitals.

Voluntary industry codes, federal guidance documents and a variety of state laws address the tracking and reporting of marketing practices relative to gifts given and other expenditures made to doctors and other healthcare professionals. In addition to impacting our marketing and educational programs, internal business processes will be affected by the numerous legal requirements and regulatory guidance at the state, federal and industry levels.

International Regulation

International sales of medical devices are subject to foreign government regulations, which may vary substantially from country to country. The time required to obtain approval in a foreign country may be longer or shorter than that required for FDA approval and the requirements may differ. For example, the primary regulatory environment in Europe with respect to medical devices is that of the European Union, which includes most of the major countries in Europe. Other countries, such as Switzerland, have voluntarily adopted laws and regulations that mirror those of the European Union with respect to medical devices. The European Union has adopted numerous directives and standards regulating the design, manufacture, clinical trials, labeling and adverse event reporting for medical devices. Devices that comply with the requirements of a relevant directive will be entitled to bear the CE conformity marking, indicating that the device conforms to the essential requirements of the applicable directives and, accordingly, can be commercially distributed throughout the European Union, although actual implementation of these directives may vary on a country-by-country basis. The method of assessing conformity varies depending on the class of the product, but normally involves a combination of submission of a design dossier, self-assessment by the manufacturer, a third-party assessment and, review of the design dossier by a “Notified Body.” This third-party assessment generally consists of an audit of the manufacturer’s quality system and manufacturing site, as well as review of the technical documentation used to support application of the CE Mark to one’s product and possibly specific testing of the manufacturer’s product. An assessment by a Notified Body of one country within the European Union is required in order for a manufacturer to commercially distribute the product throughout the European Union.

In addition, any international expansion, operations and sales that we undertake will require us to comply with the U.S. Foreign Corrupt Practices Act and similiar anti-bribery laws in other jurisdictions and with U.S. and foreign export control, trade embargo and custom laws.

Environmental Regulation

Our operations are subject to regulatory requirements relating to the environment, waste management and health and safety matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of hazardous substances. We are currently classified and licensed as a Very Small Quantity Hazardous Waste Generator within Ramsey County, Minnesota. There are no regulated wastes requiring licensing in our Texas facility.

Employees

As of June 30, 2014, we had 479 employees, including 112 employees in manufacturing, 224 employees in sales, 33 employees in marketing, 33 employees in clinical, 43 employees in general and administrative, and 34 employees in research and development, all of which are full-time employees. None of our employees are represented by a labor union or are parties to a collective bargaining agreement, and we believe that our employee relations are good.

Item 1A.    Risk Factors.

Risks Relating to Our Business and Operations

We have a history of net losses and a short commercialization experience, and we are likely to continue to incur losses.

We are not profitable and have incurred net losses in each fiscal year since our formation in 1989. In particular, we had net losses of $35.3 million in fiscal 2014, $24.0 million in fiscal 2013 and $16.8 million in fiscal 2012. As of June 30, 2014, we had an accumulated deficit of approximately $238.6 million. We commenced commercial sales of the PAD Systems in September 2007 and the CAD System in October 2013, and our short commercialization experience makes it difficult for us to predict future performance. We also expect to incur significant additional expenses for sales and marketing, research and development and manufacturing as we continue to commercialize the PAD and CAD Systems and additional expenses as we seek to develop and commercialize future versions of the PAD and CAD Systems and any future products. Additionally, we expect that our general and administrative expenses will increase as our business grows. As a result, our operating losses are likely to continue.

We may be unable to sustain our revenue growth.

Our revenue has grown in each of the fiscal years since we commenced commercial sales of the PAD Systems in September 2007. Our ability to continue to increase our revenues in future periods will depend on our ability to increase sales of the PAD Systems and generate significant sales from the CAD System and new and improved products we introduce, which will in turn depend in part on our success in growing our customer base and reorders from those customers, and obtaining new applications for our technology. We may not be able to generate, sustain or increase revenues on a quarterly or annual basis. If we cannot achieve or sustain revenue growth for an extended period, our financial results will be adversely affected and our stock price may decline.

Economic conditions may adversely affect our business.

Adverse worldwide economic conditions may negatively impact our business. A significant change in the liquidity or financial condition of our customers could cause unfavorable trends in their purchases and also in our receivable collections and additional allowances may be required, which could adversely affect our operating results. Adverse worldwide economic conditions may also adversely impact our suppliers' ability to provide us with materials and components, which could adversely affect our business and operating results.

The PAD Systems, the CAD System and future products may never achieve broad market acceptance.

The PAD and CAD Systems and future products we may develop may never gain broad market acceptance among physicians, patients and the medical community. The degree of market acceptance of any of our products will depend on a number of factors, including:

the actual and perceived effectiveness and reliability of our products;
the prevalence and severity of any adverse patient events involving our products;
the results of any clinical trials relating to use of our products;
the availability, relative cost and perceived advantages and disadvantages of alternative technologies or treatment methods for conditions treated by our products;
the degree to which treatments using our products are approved for reimbursement by public and private insurers;
the degree to which physicians adopt the PAD and CAD Systems;
the extent to which we are successful in educating physicians about PAD and coronary artery disease in general and the existence and benefits of the PAD and CAD Systems in particular;
the strength of our marketing and distribution infrastructure; and
the level of education and awareness among physicians and hospitals concerning our products.

Failure of the PAD and CAD Systems to significantly penetrate current or new markets would negatively impact our business, financial condition and results of operations.


16


Our customers may not be able to achieve adequate reimbursement for using the PAD and CAD Systems which could affect the acceptance of our products and cause our business to suffer.

The availability of insurance coverage and reimbursement for newly approved medical devices and procedures is uncertain. The commercial success of our products is substantially dependent on whether third-party insurance coverage and reimbursement for the use of such products and related services are available. We expect our products to continue to be purchased by hospitals and other providers who will then seek reimbursement from various public and private third-party payors, such as Medicare, Medicaid and private insurers, for the services provided to patients. While third-party payors are currently providing reimbursement for our products, we can give no assurance that these third-party payors will continue to provide adequate reimbursement for use of the PAD and CAD Systems to permit hospitals and doctors to consider the products cost-effective for patients requiring treatment, or that current reimbursement levels for our products will continue. In addition, the overall amount of reimbursement available for PAD and CAD treatment could decrease in the future. Failure by hospitals and other users of our products to obtain sufficient reimbursement could cause our business to suffer.
 
Medicare, Medicaid, health maintenance organizations and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement, and, as a result, they may not cover or provide adequate payment for use of our products. In order to position our products for acceptance by third-party payors, we may have to agree to lower prices than we might otherwise charge.

Governmental and private sector payors have instituted initiatives to limit the growth of healthcare costs using, for example, price regulation or controls and competitive pricing programs. Some third-party payors also require demonstrated superiority, on the basis of randomized clinical trials, or pre-approval of coverage, for new or innovative devices or procedures before they will reimburse healthcare providers who use such devices or procedures. It is uncertain whether our current products or any future products we may develop will be viewed as sufficiently cost-effective to warrant adequate coverage and reimbursement levels.

If third-party coverage and reimbursement for our products is limited or not available, the acceptance of our products and, consequently, our business will be substantially harmed.

Healthcare reform legislation could adversely affect our operating results and financial condition.

There have been and continue to be proposals by the federal government, state governments, regulators and third-party payors to control healthcare costs and, more generally, to reform the U.S. healthcare system, some of which have been enacted into law, such as the Patient Protection and Affordable Care Act, or the Patient Act. The Patient Act imposes significant new taxes on medical device makers and these taxes have begun to adversely affect our financial results. The Patient Act and any additional healthcare proposals and laws that may be enacted in the future could also limit the prices we are able to charge for our products or the amounts of reimbursement available for our products and could limit the acceptance and availability of our products. The Patient Act and future healthcare legislation could adversely affect our revenue and financial condition.

Our financial performance may be adversely affected by medical device tax provisions in the health care reform legislation.

The imposition of the 2.3% medical device excise tax enacted as part of the Patient Act has required, and will continue to require, us to identify ways to reduce spending in other areas or raise additional capital to offset the increased expense. We have not been able to pass along the cost of the tax to our customers or offset the cost of the tax through higher sales volumes resulting from the expansion of health insurance coverage, and do not expect to be able to do so in the future, because of the demographics of the current uninsured population. The regulations put forth by the U.S. Department of Treasury in late 2012 did little to lessen the burden of complying with the excise tax statute. Ongoing implementation of this legislation could have a material adverse effect on our results of operations and cash flows.

We have limited data and experience regarding the safety and efficacy of the PAD and CAD Systems. Any long-term data that is generated may not be positive or consistent with our limited short-term data, which would affect market acceptance of these products.

Because our technology is relatively new in the treatment of PAD and CAD, we have performed clinical trials only with limited patient populations. The long-term effects of using the PAD and CAD Systems in a large number of patients have not been studied and the results of short-term clinical use of the PAD or CAD Systems do not necessarily predict long-term clinical benefits or reveal long-term adverse effects.


17


Clinical trials conducted with the PAD and CAD Systems have involved procedures performed by physicians who are very technically proficient. Consequently, both short and long-term results reported in these studies may be significantly more favorable than typical results achieved by physicians, which could negatively impact market acceptance of the PAD and CAD Systems and materially harm our business.

We face significant competition, must innovate to stay competitive, and may be unable to sell the PAD or CAD Systems at profitable levels.

The market for medical devices is highly competitive, dynamic and marked by rapid and substantial technological development and product innovation. Our ability to compete depends on our ability to innovate successfully, and while certain barriers exist to entry into our market we cannot assure that new entrants or existing competitors will not be able to develop products that compete directly with our products. We compete against very large and well-known stent and balloon angioplasty device manufacturers, atherectomy catheter manufacturers, pharmaceutical companies, and companies that provide products used by surgeons in peripheral and coronary bypass procedures. We may have difficulty competing effectively with these competitors because of their well-established positions in the marketplace, significant financial and human capital resources, established reputations and worldwide distribution channels.

Our competitors may:

develop and patent processes or products earlier than we will;
obtain regulatory clearances or approvals for competing medical device products more rapidly than we will;
market their products more effectively than we will; or
develop more effective or less expensive products or technologies that render our technology or products obsolete or non-competitive.

We have encountered and expect to continue to encounter potential customers who, due to existing relationships with our competitors, are committed to or prefer the products offered by these competitors. If we are unable to compete successfully, our revenue will suffer. Increased competition might lead to price reductions and other concessions that might adversely affect our operating results. Competitive pressures may decrease the demand for our products and could adversely affect our financial results.

We have limited commercial manufacturing experience and could experience difficulty in producing the PAD and CAD Systems or may need to depend on third parties to manufacture the products.

We have limited experience in commercially manufacturing the PAD Systems, even less experience in commercially manufacturing the CAD System and no experience manufacturing these products in the volume that we anticipate will be required if we achieve planned levels of commercial sales. As a result, we may not be able to develop and implement efficient, low-cost manufacturing capabilities and processes that will enable us to manufacture the PAD and CAD Systems or future products in significant volumes, while meeting the legal, regulatory, quality, price, durability, engineering, design and production standards required to market our products successfully.

The forecasts of demand we use to determine order quantities and lead times for components purchased from outside suppliers may be incorrect. Our failure to obtain required components or subassemblies when needed and at a reasonable cost would adversely affect our business.

In addition, we may in the future need to depend upon third parties to manufacture the PAD and CAD Systems and future products. Any difficulties in locating and hiring third-party manufacturers, or in the ability of third-party manufacturers to supply quantities of our products at the times and in the quantities we need, could have a material adverse effect on our business.

We depend upon third-party suppliers, including single source suppliers to us and our customers, making us vulnerable to supply problems and price fluctuations.

We rely on third-party suppliers to provide us with certain components of our products and to provide key components or supplies to our customers for use with our products. We rely on single source suppliers for certain components of the PAD and CAD Systems. We depend on our suppliers to provide us and our customers with materials in a timely manner that meet our and their quality, quantity and cost requirements. These suppliers may encounter problems during manufacturing for a variety of reasons, any of which could delay or impede their ability to meet our demand and our customers' demands.


18


Any supply interruption from our suppliers or failure to obtain additional suppliers for any of the components used in our products would limit our ability to manufacture our products and could have a material adverse effect on our business, financial condition and results of operations.

We may need to increase the size of our organization and we may experience difficulties managing growth. If we are unable to manage the anticipated growth of our business, our future revenue and operating results may be adversely affected.

The growth we may experience in the future may provide challenges to our organization, requiring us to rapidly expand our sales and marketing personnel and manufacturing operations. Rapid expansion in personnel may result in less experienced people producing and selling our products, which could result in unanticipated costs and disruptions to our operations. If we cannot scale and manage our business appropriately, our anticipated growth may be impaired and our financial results will suffer.

We intend to sell our products internationally in the future, but we may experience difficulties in obtaining approval to do so or in successfully marketing our products internationally even if approved.

Currently, all of our revenues are in the U.S.; however, we intend to sell internationally in the future and have commenced the process of seeking approval to do so in both Europe and Japan. There can be no guarantee that we will receive approval to sell our products internationally, nor can there be any guarantee that any sales would result even if such approval is received. Additionally, movement into international markets would subject us and our products to different and increased laws and regulations, which could negatively affect our financial results and increase our regulatory expenses.

We may require additional financing, and our failure to obtain additional financing when needed could force us to delay, reduce or eliminate our product development programs or commercialization efforts.

We may be dependent on additional financing to execute our business plan. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. In the event we need or desire additional financing, we may be unable to obtain it by borrowing money in the credit markets or raising money in the capital markets. If adequate funds are not available on a timely basis, we may terminate or delay the development of one or more of our products, or delay establishment of sales and marketing capabilities or other activities necessary to commercialize our products.

We face a risk of non-compliance with the financial covenants in our loan and security agreements with Silicon Valley Bank and Partners for Growth.

We are party to loan and security agreements with Silicon Valley Bank and Partners for Growth. These agreements require us to maintain, among other things, a monthly specified liquidity ratio and contain customary events of default, including, among others, the failure to comply with certain covenants or other agreements. Upon the occurrence and during the continuation of an event of default, amounts due under the agreements may be accelerated by Silicon Valley Bank or Partners for Growth. If we are unable to meet the financial or other covenants under the current loan and security agreements or negotiate future waivers or amendments of such covenants, events of default could occur under the agreements. Upon the occurrence and during the continuance of an event of default under the agreements, Silicon Valley Bank and Partners for Growth have available a range of remedies customary in these circumstances, including declaring all outstanding debt, together with accrued and unpaid interest thereon, to be due and payable, foreclosing on the assets securing the agreements and/or ceasing to provide additional loans, which could have a material adverse effect on us.

The restrictive covenants under these agreements could limit our ability to obtain future financing, withstand a future downturn in our business or the economy in general or otherwise conduct necessary corporate activities. The financial and restrictive covenants contained in the agreements could also adversely affect our ability to respond to changing economic and business conditions and place us at a competitive disadvantage relative to other companies that may be subject to fewer restrictions. Transactions that we may view as important opportunities, such as acquisitions, may be subject to the consent of Silicon Valley Bank and Partners for Growth, which consents may be withheld or granted subject to conditions specified at the time that may affect the attractiveness or viability of the transaction.







19


We are dependent on our senior management team and highly skilled personnel, and our business could be harmed if we are unable to attract and retain personnel necessary for our success.

We are highly dependent on our senior management. Our success will depend on our ability to retain senior management and to attract and retain qualified personnel in the future, including scientists, clinicians, engineers and other highly skilled personnel and to integrate current and additional personnel in all departments. The loss of members of our senior management, scientists, clinical and regulatory specialists, engineers and sales personnel could prevent us from achieving our objectives of continuing to grow our company. We do not carry key person life insurance on any of our employees.

Our stock price is volatile and subject to significant fluctuations.

The market price of our common stock could be subject to significant fluctuations. Market prices for securities of early-stage pharmaceutical, medical device, biotechnology and other life sciences companies have historically been particularly volatile. Our common stock traded as low as $18.83 and as high as $37.73 per share during the 12-month period ended June 30, 2014. Factors that may cause the market price of our common stock to fluctuate include, but are not limited to:
 
announcements of technological or medical innovations for the treatment of vascular disease;
quarterly variations in our or our competitors’ results of operations;
failure to meet estimates or recommendations by securities analysts who cover our stock;
accusations that we have violated a law or regulation;
sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders;
changes in accounting principles; and
general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.

Moreover, the stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations may also adversely affect the trading price of our common stock.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation's ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income or taxes may be limited. In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We may have experienced an ownership change in the past and we may also experience ownership changes in the future as a result of future transactions in our stock, some of which may be outside our control. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards or other pre-change tax attributes to offset U.S. federal and state taxable income or taxes may be subject to limitations.

Risks Related to Government Regulation

Our ability to market the PAD Systems in the United States is limited to use as a therapy in patients with PAD and our ability to market the CAD System in the United States is limited to use as a therapy in patients with coronary artery disease, and if we want to expand our marketing claims, we will need to file for additional FDA clearances or approvals and conduct further clinical trials, which would be expensive and time consuming and may not be successful.

The PAD Systems received FDA 510(k) clearances in the United States for use as a therapy in patients with PAD, and in October 2013, we received PMA approval to use the CAD System as a therapy in patients with coronary artery disease. These general clearances and approvals restrict our ability to market or advertise the PAD Systems and the CAD System beyond these uses and could affect our growth.

If we determine to market our orbital technology in the United States for other uses, we would need to conduct further clinical trials and obtain premarket approval from the FDA. Clinical trials are complex, expensive, time consuming, uncertain and subject to substantial and unanticipated delays. There is no assurance that we will be able to obtain FDA approval to use our orbital atherectomy technology for applications other than the treatment of PAD and coronary artery disease.


20


We are or will be subject to an extensive set of post-market controls that apply to us as we commercialize our products, including annual PMA reports, Medical Device Reports on serious adverse events, complaint handling and analysis under the FDA's Quality System Regulation ("QSR"), export controls, advertising and promotion requirements, and potential post-market studies required by the FDA.

We and our suppliers are also subject to regulation by various state authorities, which may inspect our or our suppliers' facilities and manufacturing processes and enforce state regulations. Failure to comply with applicable state regulations may result in seizures, injunctions or other types of enforcement actions.

Our promotion of the PAD and CAD Systems is closely controlled by the FDA and enforcement activities could limit our ability to inform potential customers of the features of the products.

The PAD Systems or the CAD System may in the future be subject to product recalls that could harm our reputation and product liability claims that could exceed the limits of available insurance coverage.

The FDA and similar governmental authorities in other countries have the authority to require the recall of commercialized products in the event of material regulatory deficiencies or defects in design or manufacture. For example, since commercialization of the PAD Systems, we have had minor instances of recall involving a single lot of Diamondback 360 Peripheral devices, two boxes of ViperWire products, and 70 lots of Stealth 360º devices, related to “Use By” date labeling issues; a recall of unused ViperSheath products, which we formerly distributed for Thomas Medical Products; a recall involving six lots of Stealth 360º micro crown devices due to the potential for an insufficient solder bond; a recall of 318 Diamondback 318 Coronary devices due to incorrect saline catheter specifications; and a recall involving 48 Diamondback 360 Peripheral devices due to issues with the polymer coating on the saline sheath. Any recalls of our products or products that we distribute would divert managerial and financial resources, harm our reputation with customers and have an adverse effect on our financial condition and results of operations.

Also, if the PAD or CAD Systems are defectively designed, manufactured or labeled, contain defective components or are misused, we may become subject to costly litigation by our customers or their patients. The use, misuse or off-label use of the PAD or CAD Systems may result in injuries that lead to product liability suits, which could be costly to our business. We cannot prevent a physician from using the PAD or CAD Systems for off-label applications. While we have product liability insurance coverage for our products and intend to maintain such insurance coverage in the future, there can be no assurance that we will be adequately protected from claims that are brought against us.

We are subject to many laws and governmental regulations and any adverse regulatory action may materially adversely affect our financial condition and business operations.

The PAD and CAD Systems and related manufacturing processes, clinical data, adverse events, recalls or corrections and promotional activities are subject to extensive regulation by the FDA and other regulatory bodies. In particular, we are required to comply with the QSR and other regulations, which cover the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of any product for which we obtain marketing clearance or approval. We are also responsible for the quality of components received by our suppliers. Failure to comply with the QSR requirements or other statutes and regulations administered by the FDA and other regulatory bodies, or failure to adequately respond to any observations, could result in, among other things:

warning or other letters from the FDA;
fines, injunctions and civil penalties;
product recall or seizure;
unanticipated expenditures;
delays in clearing or approving or refusal to clear or approve products;
withdrawal or suspension of approval or clearance by the FDA or other regulatory bodies;
orders for physician notification or device repair, replacement or refund;
operating restrictions, partial suspension or total shutdown of production or clinical trials; and
criminal prosecution.

If any of these actions were to occur, it would harm our reputation and cause our product sales to suffer.


21


Our operations are also subject to regulatory requirements relating to the environment, waste management and health and safety matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of hazardous substances. Environmental laws and regulations could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations.

In addition, our relationships with physicians, hospitals and the marketers of our products are subject to scrutiny under various federal anti-kickback, self-referral, false claims and similar laws, often referred to collectively as healthcare fraud and abuse laws, as further described below.

If our operations are found to be in violation of these laws, we, as well as our employees, may be subject to penalties, including monetary fines, civil and criminal penalties, exclusion from federal and state healthcare programs, including Medicare, Medicaid, Veterans Administration health programs, workers' compensation programs and TRICARE (the healthcare system administered by or on behalf of the U.S. Department of Defense for uniformed services beneficiaries, including active duty and their dependents, retirees and their dependents), and forfeiture of amounts collected in violation of such prohibitions, which could materially adversely affect our financial condition and business operations.

We are subject to federal and state laws prohibiting “kickbacks” and false and fraudulent claims which, if violated, could subject us to substantial penalties. Additionally, any challenges to or investigations into our practices under these laws could cause adverse publicity and be costly to respond to, and thus could harm our business.

The federal healthcare program Anti-Kickback Statute, and similar state laws, prohibit payments that are intended to induce health care professionals or others either to refer patients or to purchase, lease, order or arrange for or recommend the purchase, lease or order of healthcare products or services. A number of states have enacted laws that require pharmaceutical and medical device companies to monitor and report payments, gifts and other remuneration made to physicians and other health care professionals and health care organizations. In addition, some state statutes, most notably laws in Massachusetts and Vermont, impose outright bans on certain gifts to physicians as well as requiring reporting of payments to physicians. Some of these laws, referred to as “aggregate spend” or “gift” laws, carry substantial fines if they are violated. Beginning in August 2013, the federal Physician Payments Sunshine Act, or the Sunshine Act, which was enacted by Congress in 2010 as part of the comprehensive health care reform legislation, and the implementing Open Payments regulations under the Sunshine Act, released in February 2013, require us to collect certain data on payments and other transfers of value to physicians and teaching hospitals. Public reporting of such information commenced in June 2014.

It is widely anticipated that public reporting under the Sunshine Act and implementing Open Payments regulations will result in increased scrutiny of the financial relationships between industry, physicians and teaching hospitals. These anti-kickback, public reporting and aggregate spend laws affect our sales, marketing and other promotional activities by limiting the kinds of financial arrangements, including sales programs, we may have with hospitals, physicians or other potential purchasers or users of medical devices. They also impose additional administrative and compliance burdens on us. In particular, these laws influence, among other things, how we structure our sales offerings, including discount practices, customer support, education and training programs and physician consulting and other service arrangements. If we were to offer or pay inappropriate inducements to purchase our products, we could be subject to a claim under the federal healthcare program Anti-Kickback Statute or similar state laws. If we fail to comply with particular reporting requirements, we could be subject to penalties under applicable federal or state laws. Other federal and state laws generally prohibit individuals or entities from knowingly presenting, or causing to be presented, claims for payments to Medicare, Medicaid or other third-party payors that are false or fraudulent, or for items or services that were not provided as claimed. Although we do not submit claims directly to government healthcare programs or other payors, manufacturers can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by providing inaccurate billing or coding information to customers, by providing improper financial inducements, or through certain other activities.

In providing billing and coding information to customers, we make every effort to ensure that the billing and coding information furnished is accurate and that treating physicians understand that they are responsible for all treatment decisions. Nevertheless, we cannot provide assurance that the government will regard any billing errors that may be made as inadvertent or that the government will not examine our role in providing information to our customers and physicians concerning the benefits of therapy with our devices. Likewise, our financial relationships with customers, physicians, or others in a position to influence the purchase or use of our products may be subject to government scrutiny or be alleged or found to violate applicable fraud and abuse laws. False claims laws prescribe civil, criminal and administrative penalties for noncompliance, which can be substantial. Moreover, an unsuccessful challenge or investigation into our practices could cause adverse publicity, and be costly to respond to, and thus could harm our business and results of operations.


22


For example, on May 8, 2014, we received a letter from the U.S. Attorney’s Office for the Western District of North Carolina stating that it is investigating the Company to determine whether we had violated the False Claims Act, resulting in the submission of false claims to federal and state health care programs, including Medicare and Medicaid. The letter enclosed a Civil Investigative Demand (“CID”) for written interrogatories and document requests. We maintain rigorous policies and procedures to promote compliance with the False Claims Act and other regulatory requirements, and are working with the U.S. Attorney’s Office to promptly respond to the CID. However, we cannot predict when the investigation will be resolved, the outcome of this investigation or its potential impact on the Company.

Regulations related to “conflict minerals” may force us to incur additional expenses, may result in damage to our business reputation and may adversely impact our ability to conduct our business.

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC promulgated final rules regarding disclosure of the use of certain minerals, known as conflict minerals, that are mined from the Democratic Republic of the Congo and adjoining countries, as well as procedures regarding a manufacturer's efforts to prevent the sourcing of such minerals and metals produced from those minerals. These disclosure requirements require ongoing due diligence efforts and disclosure on Form SD in May of each year for the prior calendar year. We filed our initial Form SD in May 2014. There are costs associated with complying with these disclosure requirements, including for diligence in regards to the sources of any conflict minerals used in our products, in addition to the cost of remediation and other changes to products, processes, or sources of supply as a consequence of such verification activities. In addition, our ongoing implementation of these rules could adversely affect the sourcing, supply, and pricing of materials used in our products.

Risks Relating to Our Intellectual Property

Our inability to adequately protect our intellectual property could allow our competitors and others to produce products based on our technology, which could substantially impair our ability to compete.

Our success and ability to compete depends, in part, upon our ability to maintain the proprietary nature of our technologies. We rely on a combination of patents, copyrights and trademarks, as well as trade secrets and nondisclosure agreements, to protect our intellectual property. Our issued patents and related intellectual property may not be adequate to protect us or permit us to gain or maintain a competitive advantage. Also, we cannot assure you that any of our pending patent applications will result in the issuance of patents to us. Further, if any patents we obtain or license are deemed invalid and unenforceable, or have their scope narrowed, it could impact our ability to commercialize or license our technology and achieve competitive advantages.

Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. In addition, the laws of some foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States, if at all.

We may, in the future, need to assert claims of infringement against third parties to protect our intellectual property. The outcome of litigation to enforce our intellectual property rights in patents, copyrights, trade secrets or trademarks is highly unpredictable, could result in substantial costs and diversion of resources, and could have a material adverse effect on our financial condition, reputation and results of operations regardless of the final outcome of such litigation.

Despite our efforts to safeguard our unpatented and unregistered intellectual property rights, we may not be successful in doing so or the steps taken by us in this regard may not be adequate to detect or deter misappropriation of our technology or to prevent an unauthorized third party from copying or otherwise obtaining and using our products, technology or other information that we regard as proprietary. In addition, we may not have sufficient resources to litigate, enforce or defend our intellectual property rights. Additionally, third parties may be able to design around our patents.

We also rely on trade secrets, technical know-how and continuing innovation to develop and maintain our competitive position. In this regard, we seek to protect our proprietary information and other intellectual property by having a policy that our employees, consultants, contractors, outside scientific collaborators and other advisors execute non-disclosure and assignment of invention agreements on commencement of their employment or engagement. We cannot provide any assurance that employees and third parties will abide by the confidentiality or assignment terms of these agreements, or that we will be effective in securing necessary assignments from these third parties.

Claims of infringement or misappropriation of the intellectual property rights of others could prohibit us from commercializing products, require us to obtain licenses from third parties or require us to develop non-infringing alternatives, and subject us to substantial monetary damages and injunctive relief.

The medical technology industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. The likelihood that patent infringement or misappropriation claims may be brought against us increases as we achieve more visibility in the marketplace and introduce products to market. We are aware of numerous patents issued to third parties that relate to the manufacture and use of medical devices for the treatment of vascular disease. The owners of each of these patents could assert that the manufacture, use or sale of our products infringes one or more claims of their patents. There could also be existing patents of which we are unaware that one or more aspects of our technology may inadvertently infringe. In some cases, litigation may be threatened or brought by a patent-holding company or other adverse patent owner who has no relevant product revenues and against whom our patents may provide little or no deterrence.

Any infringement or misappropriation claim could cause us to incur significant costs, place significant strain on our financial resources, divert management's attention from our business and harm our reputation. If the relevant patents were upheld in litigation as valid and enforceable and we were found to infringe, we could be prohibited from commercializing any infringing products unless we could obtain licenses to use the technology covered by the patent or are able to design around the patent. We may be unable to obtain a license on terms acceptable to us, if at all, and we may not be able to redesign any infringing products to avoid infringement.

Item 1B.        Unresolved Staff Comments.

None.

Item 2.        Properties.

Our principal executive offices are located in a 47,000 square foot facility in St. Paul, Minnesota. We have leased this facility through November 2015 with an option to renew through November 2020. In September 2013, we leased an additional 13,000 square foot office facility located in St. Paul, Minnesota which is leased through November 2015. These facilities accommodate our research and development, sales, marketing, manufacturing, finance and administrative activities.

In September 2009, we entered into an agreement to lease a 46,000 square foot production facility in Pearland, Texas beginning in April 2010 through March 2020. This facility primarily accommodates additional manufacturing activities.

In June 2014, we announced plans to build a new corporate headquarters in New Brighton, Minnesota. The 125,000-square-foot, two-story building will have space for more than 500 employees and contain dedicated research and development, training and education, and manufacturing facilities. This new facility will replace the two St. Paul, Minnesota leased facilities above.

We believe that our current facilities, including the new corporate headquarters, are substantially adequate for our current and anticipated future needs for the foreseeable future.

Item 7.        Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of financial condition and results of operations together with our consolidated financial statements and the related notes included elsewhere in this Form 10-K. This discussion and analysis contains forward-looking statements about our business and operations, based on current expectations and related to future events and our future financial performance, that involve risks and uncertainties. Our actual results may differ materially from those we currently anticipate as a result of many important factors, including the factors we describe under “Risk Factors” and elsewhere in this Form 10-K.

OVERVIEW

We are a medical device company focused on developing and commercializing interventional treatment systems for vascular disease. Our peripheral arterial disease ("PAD") products, the Stealth 360°® PAD System (the "Stealth 360"), the Diamondback 360® PAD Systems (the “Diamondback 360 Peripheral”) and the Diamondback Predator 360°® (the "Predator 360") are catheter-based platforms capable of treating a broad range of plaque types in leg arteries both above and below the knee and address many of the limitations associated with existing treatment alternatives. In March 2014, we received approval for the Diamondback 360® 60cm Peripheral OAS access device which allows physicians to treat PAD patients in the small and tortuous vessels located below the knee through alternative access sites in the ankle or foot. We have also obtained approval to market our Diamondback 360® Coronary Orbital Atherectomy System ("CAD System") as a treatment for severely calcified coronary arteries.

We were incorporated as Replidyne, Inc. ("Replidyne") in Delaware in 2000. On February 25, 2009, Replidyne completed its business combination with Cardiovascular Systems, Inc., a Minnesota corporation (“CSI-MN”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of November 3, 2008 (the “Merger Agreement”). Pursuant to the Merger Agreement, CSI-MN continued after the merger as the surviving corporation and a wholly-owned subsidiary of Replidyne. Replidyne changed its name to Cardiovascular Systems, Inc. (“CSI”) and CSI-MN merged with and into CSI, with CSI continuing after the merger as the surviving corporation. These transactions are referred to herein as the “merger.” Replidyne was a biopharmaceutical company focused on discovering, developing, in-licensing and commercializing anti-infective products.
    
CSI-MN was incorporated in Minnesota in 1989. From 1989 to 1997, we engaged in research and development on several different product concepts. Since 1997, we have devoted substantially all of our resources to the development of the PAD Systems and, since 2007, to the approval of our CAD System.


28


From 2003 to 2005, we conducted numerous bench and animal tests in preparation for application submissions to the U.S. Food and Drug Administration ("FDA"). We initially focused our testing on providing a solution for coronary in-stent restenosis, but later changed the focus to PAD. In 2006, we obtained an investigational device exemption from the FDA to conduct our pivotal OASIS PAD clinical trial, which was completed in January 2007. The OASIS clinical trial was a prospective 20-center study that involved 124 patients with 201 lesions.

In August 2007, the FDA granted us 510(k) clearance for the use of the Diamondback 360 Peripheral as a therapy in patients with PAD. We commenced commercial introduction of the Diamondback 360 Peripheral in the United States in September 2007. We were granted 510(k) clearance of the Predator 360 in March 2009 and Stealth 360 in March 2011. We received 510(k) clearance of the Diamondback 360 60cm Peripheral OAS in March 2014. We market the PAD Systems in the United States through a direct sales force and expend significant capital on our sales and marketing efforts to expand our customer base and utilization per customer. We assemble at our facilities the saline infusion pump and the single-use catheter used in the PAD Systems with components purchased from third-party suppliers, as well as with components manufactured in-house. Supplemental products are purchased from third-party suppliers.

We have developed modified versions of the PAD System to treat coronary arteries. A coronary application required us to conduct a clinical trial and file a premarket application ("PMA"), and obtain approval from the FDA. In March 2013, we completed submission of our PMA application to the FDA for our orbital atherectomy system to treat calcified coronary arteries. In October 2013, we received PMA from the FDA to market the Diamondback 360 Coronary Orbital Atherectomy System (“OAS”) as a treatment for severely calcified coronary arteries. We commenced a controlled commercial launch of CAD System following receipt of PMA approval.

As of June 30, 2014, we had an accumulated deficit of $238.6 million. We expect our losses to continue as we invest in sales, marketing, medical education, clinical studies and product research and development for our next phase of growth in the peripheral market and broaden the commercial launch of our CAD System. To date, we have financed our operations primarily from the issuance of common and preferred stock, convertible promissory notes, and debt.

FINANCIAL OVERVIEW

Revenues.    We derive substantially all of our revenues from the sale of PAD Systems, the CAD System and other ancillary products. The PAD and CAD Systems each use a disposable, single-use, low-profile catheter that travels over our proprietary ViperWire guidewire. The systems use a saline infusion pump as a power supply for the operation of the catheter. Our ancillary products include the ViperSlide Lubricant and ViperTrack Radiopaque Tape. We also have an exclusive distribution agreement with Asahi to market its peripheral guide wire line in the United States.

Cost of Goods Sold.    We assemble the single-use catheter with components purchased from third-party suppliers, as well as with components manufactured in-house. The infusion pump and guidewires are purchased from third-party suppliers. Our cost of goods sold consists primarily of raw materials, direct labor, and manufacturing overhead.

Selling, General and Administrative Expenses.    Selling, general and administrative expenses include compensation for executive, sales, marketing, finance, information technology, human resources and administrative personnel, including stock-based compensation. Other significant expenses include travel and marketing costs and professional fees.

Research and Development Expenses.    Research and development expenses include costs associated with the design, development, testing, enhancement and regulatory approval of our products. Research and development expenses include employee compensation including stock-based compensation, supplies and materials, patent expenses, consulting expenses, travel and facilities overhead. We also incur significant expenses to operate clinical trials, including trial design, third-party fees, clinical site reimbursement, data management and travel expenses. All research and development expenses are expensed as incurred. Approved patent applications are capitalized and amortized using the straight-line method over their remaining estimated lives. Patent amortization begins at the time of patent application approval, and does not exceed 20 years.

Interest and Other, Net.    Interest and other, net primarily includes interest expense (including premium and discount amortization), interest income, change in the fair value of the debt conversion option, debt refinancing costs, and net write-offs upon debt conversion (option and unamortized premium or discount).

Interest Expense. Interest expense (including premium and discount amortization) results from outstanding debt balances and debt premiums and discounts.
Interest Income. Interest income is attributed to interest earned on deposits in investments that consist of money market funds.

29


Change in Fair Value of Debt Conversion Option. Change in fair value of debt conversion option represents the period to period change in fair value of the debt conversion option associated with outstanding convertible debt.
Net Write-offs Upon Debt Conversion. Net write-offs upon debt conversion are the result of the conversion of convertible debt, and include the write-off of the related debt conversion option and any unamortized debt premium or discount.
Other. Other consists of miscellaneous non-operating expenses, including state taxes.

Net Operating Loss Carryforwards.    We have established valuation allowances to fully offset our deferred tax assets due to the uncertainty about our ability to generate the future taxable income necessary to realize these deferred assets, particularly in light of our historical losses. The future use of net operating loss carryforwards is dependent on us attaining profitable operations and will be limited in any one year under Internal Revenue Code Section 382 due to significant ownership changes (as defined in Section 382) resulting from our equity financings. At June 30, 2014, we had net operating loss carryforwards for federal and state income tax reporting purposes of approximately $159.2 million, which will expire at various dates through fiscal 2033.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

Our management's discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect amounts reported in those statements. Our estimates, assumptions and judgments, including those related to revenue recognition, allowance for doubtful accounts, excess and obsolete inventory, the debt conversion option, and stock-based compensation are updated as appropriate at least quarterly. We use authoritative pronouncements, our technical accounting knowledge, cumulative business experience, valuation specialists, judgment and other factors in the selection and application of our accounting policies. While we believe that the estimates, assumptions and judgments that we use in preparing our consolidated financial statements are appropriate, these estimates, assumptions and judgments are subject to factors and uncertainties regarding their outcome. Therefore, actual results may materially differ from these estimates.

Some of our significant accounting policies require us to make subjective or complex judgments or estimates. An accounting estimate is considered to be critical if it meets both of the following criteria: (1) the estimate requires assumptions about matters that are highly uncertain at the time the accounting estimate is made, and (2) different estimates that reasonably could have been used, or changes in the estimate that are reasonably likely to occur from period to period, would have a material impact on the presentation of our financial condition, results of operations, or cash flows. 

Revenue Recognition.    We sell the majority of our products via direct shipment to hospitals or office-based labs. We recognize revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectability is reasonably assured. We record estimated sales returns, discounts and rebates as a reduction of net sales.

Costs related to products delivered are recognized in the period the revenue is recognized. Cost of goods sold consists primarily of raw materials, direct labor, and manufacturing overhead.

Allowance for Doubtful Accounts.    We maintain an allowance for doubtful accounts. This allowance is an estimate and is regularly evaluated for adequacy by taking into consideration factors such as past experience, credit quality of the customer base, age of the receivable balances, both individually and in the aggregate, and current economic conditions that may affect a customer’s ability to pay. Provisions for the allowance for doubtful accounts attributed to bad debt are recorded in general and administrative expenses.

Excess and Obsolete Inventory.    We have inventories that are principally comprised of capitalized direct labor and manufacturing overhead, raw materials and components, and finished goods. Due to the technological nature of our products, there is a risk of obsolescence for changes in our technology and the market, which is impacted by technological developments and events. Accordingly, we write down our inventories as we become aware of any situation where the carrying amount exceeds the estimated realizable value based on assumptions about future demands and market conditions. The evaluation includes analysis of inventory levels, expected product lives, product at risk of expiration, sales levels by product and projections of future sales demand.


30


Debt Conversion Option.    The fair value of the debt conversion option is related to the loan and security agreement with Partners for Growth ("PFG") and has been included as a component of debt conversion option and other assets on our balance sheet. The Monte Carlo option pricing model was used to determine the value of the debt conversion option and includes various inputs including historical volatility, stock price simulations, and the assessed behavior of us and PFG based on those simulations. In fiscal 2014, PFG converted all of the remaining loans (see Note 3 to the consolidated financial statements for additional information).

Stock-Based Compensation.    We have stock-based compensation plans, which includes stock options, nonvested share awards, and an employee stock purchase plan. We determine the fair value of our option awards using option-pricing models. We determine the fair value of nonvested share awards with market conditions using the Monte Carlo simulation. Fair value of nonvested share awards that vest based upon performance or time conditions is determined by the closing market price of our stock on the date of grant, as determined by management and the board of directors. Stock-based compensation expense is recognized ratably over the requisite service period for the awards expected to vest. Management's key assumptions are developed with input from independent third-party valuation advisors.

Legal Proceedings.    In accordance with FASB guidance, we record a liability in our consolidated financial statements related to legal proceedings when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is possible, but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed in the notes to the consolidated financial statements. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded.

Revenues.    Revenues increased by $32.7 million, or 31.5%, from $103.9 million for the year ended June 30, 2013 to $136.6 million for the year ended June 30, 2014. This increase was primarily attributable to a $24.2 million, or 26.5%, increase in the number of PAD Systems sold, which reflects a 30.8% increase in number of devices sold, partially offset by a 3.3% reduction in average selling prices. Additionally, the sale of the CAD System contributed approximately $5.0 million in revenues following our PMA approval in October 2013. Other product revenue also increased $3.5 million, or 28.0%, during the year ended June 30, 2014 as compared to the year ended June 30, 2013, primarily driven by increased sales of PAD and CAD Systems, which the products support. Currently, all of our revenues are in the United States; however, we intend to sell internationally in the future and have commenced the process of seeking approval to do so in both Europe and Japan. We expect our revenue to increase as we continue to increase the number of physicians using the devices, increase the usage per physician, introduce new and improved products, generate additional clinical data, continue the commercial launch of our CAD System, and expand into new geographies.

Cost of Goods Sold.    Cost of goods sold increased by $6.6 million, or 27.3%, from $24.4 million for the year ended June 30, 2013 to $31.0 million for the year ended June 30, 2014. These amounts represent the cost of materials, labor and overhead for single-use catheters, guidewires, control units, and other ancillary products. The increase was due to an increase in the quantities of products sold, partially offset by lower indirect costs per unit from higher production volumes and manufacturing efficiencies. The increase in gross margin from 76.5% during the year ended June 30, 2013, to 77.3% for the year ended June 30, 2014, was primarily due to lower indirect costs per unit, partially offset by lower average selling prices of PAD Systems. Cost of goods sold for the years ended June 30, 2014 and 2013 includes $0.7 million and $0.4 million, respectively, for stock-based compensation. We expect that gross margin in fiscal 2015 will improve slightly compared to fiscal 2014 as cost improvements will be made throughout the year. Quarterly fluctuations could occur based on production volumes, timing of new product introductions, sales mix, pricing changes, or other unanticipated circumstances.

Selling, General and Administrative Expenses.    Selling, general, and administrative expenses increased by $31.3 million, or 36.1%, from $86.7 million for the year ended June 30, 2013 to $118.0 million for the year ended June 30, 2014. Our selling, general and administrative expenses for the year ended June 30, 2014 have increased due to our commercial CAD System launch, the expansion of our sales and marketing organization, increased variable compensation, increased promotion and medical education programs, higher stock-based compensation, increased costs related to health care policy initiatives and higher medical device excise taxes. Selling, general, and administrative expenses for the years ended June 30, 2014 and 2013 include $9.2 million and $6.2 million, respectively, for stock-based compensation. We expect our selling, general and administrative expenses to increase in the future as a result of the costs associated with expanding our sales and marketing organization and medical education and other programs to further commercialize our PAD products and expanding the commercial launch of our CAD System.

Research and Development Expenses.    Research and development expenses increased by $5.9 million, or 38.4%, from $15.2 million for the year ended June 30, 2013 to $21.1 million for the year ended June 30, 2014. Research and development expenses relate to the specific projects to develop new products or expand into new markets, such as the development of new versions of the PAD and CAD Systems, shaft designs, crown design, and PAD and CAD clinical studies. The increase primarily related to additional product development projects and clinical studies which began in fiscal 2014, and the related increase in headcount. Research and development expenses for the year ended June 30, 2014 and 2013 include $1.1 million and $0.8 million, respectively, for stock-based compensation. As we continue to expand our product portfolio and clinical studies within the PAD and CAD markets, we generally expect to incur research and development expenses significantly above amounts incurred for the year ended June 30, 2014. Fluctuations could occur based on the number of projects and studies and the timing of expenditures.

Interest and Other, net.    Interest and other, net was $(1.8) million and $(1.6) million for the years ended June 30, 2014 and 2013, respectively. The increase was primarily due to the change in fair value of the debt conversion option which was associated with the previously outstanding convertible debt (changes in fair value was primarily driven by the change in the market value of our common stock) and the write-off's associated with the debt conversions. Slightly offsetting this was a decrease in interest expense as a result of lower debt balances as well as debt premium and discount amortization.

Net Loss.    Net loss for the year ended June 30, 2014 was $(35.3) million, compared to $(24.0) million for the year ended June 30, 2013. Our net loss has increased as a result of increased operating expenses, partially offset by higher gross profit.

Revenues. Revenues increased by $21.4 million, or 26.0%, from $82.5 million for the year ended June 30, 2012 to $103.9 million for the year ended June 30, 2013. This increase was primarily attributable to an $18.2 million, or 25.0%, increase in the number of PAD Systems sold, which reflects a 26.0% increase in the number of devices sold, partially offset by a 0.8% reduction in average selling prices. Other product revenue increased $3.2 million, or 33.6%, during the year ended June 30, 2013, compared to the year ended June 30, 2012, primarily driven by increased sales of PAD Systems, which the products support.

Cost of Goods Sold. Cost of goods sold increased by $5.2 million, or 26.9%, from $19.2 million for the year ended June 30, 2012 to $24.4 million for the year ended June 30, 2013. These amounts represent the cost of materials, labor and overhead for single-use catheters, guidewires, control units, pumps, and other supplemental products. The decrease in gross margin from 76.7% during the year ended June 30, 2012, to 76.5% for the year ended June 30, 2013, was primarily due to a higher mix of Stealth 360 sales, which carried a higher unit cost than its predecessor product, and to lower average selling prices, partially offset by the favorable effect of increased production volumes. Cost of goods sold for the years ended June 30, 2013 and 2012 includes $0.4 million and $0.3 million, respectively, for stock-based compensation.

Selling, General and Administrative Expenses. Selling, general, and administrative expenses increased by $20.4 million, or 30.7%, from $66.4 million for the year ended June 30, 2012 to $86.7 million for the year ended June 30, 2013. Our selling, general and administrative expenses for the year ended June 30, 2013 increased due to increased variable compensation, expansion in our sales and marketing organizations, increased medical education programs, and the medical device excise tax, which became effective January 1, 2013 and resulted in an expense of $1.0 million for the year ended June 30, 2013. Selling, general, and administrative expenses for the years ended June 30, 2013 and 2012 include $6.2 million and $4.4 million, respectively, for stock-based compensation.

Research and Development Expenses. Research and development expenses increased by $3.8 million, or 33.8%, from $11.4 million for the year ended June 30, 2012, to $15.2 million for the year ended June 30, 2013. Research and development expenses relate to the development of new products, enhancement of existing products and PAD and CAD clinical trials. The increase in clinical expenses was related to the advancement of the ORBIT II coronary trial and related expansion of the clinical organization. Research and development expenses for the years ended June 30, 2013 and 2012 include $0.8 million and $0.5 million, respectively, for stock-based compensation.

Interest and Other, net. Interest and other, net was $(1.6) million and $(2.3) million for the years ended June 30, 2013 and 2012, respectively. The decrease was primarily due to the change in fair value of the debt conversion option which was associated with the previously outstanding convertible debt and changes in its fair value were primarily driven by the change in the market value of our common stock. Slightly offsetting this was an increase in net write-offs upon conversion which were the result of the conversion of convertible debt and includes the write-off of the debt conversion option and any unamortized debt premium or discount.

Net Loss. Net loss for the year ended June 30, 2013 was $(24.0) million, compared to $(16.8) million for the year ended June 30, 2012. Our net loss increased as a result of increased operating expenses, partially offset by higher gross profit.

NON-GAAP FINANCIAL INFORMATION

To supplement our consolidated financial statements prepared in accordance with GAAP, our management uses a non-GAAP financial measure referred to as “Adjusted EBITDA.” The following table sets forth, for the periods indicated, a reconciliation of Adjusted EBITDA to the most comparable U.S. GAAP measure expressed as dollar amounts (in thousands):

Add: Depreciation and amortization

Adjusted EBITDA
$
(21,194
)
 
$
(14,004
)

The decrease in Adjusted EBITDA of $7.2 million, or 51.3%, is primarily the result of the $11.1 million, or 49.4%, increase in the loss from operations. The loss from operations was significantly impacted by increases in operating expenses, slightly offset by an increase in gross profit.

Adjusted EBITDA was also impacted by an increase in stock-based compensation and increase in depreciation and amortization. Stock-based compensation increased $3.5 million, or 46.8%, from $7.4 million for the year ended June 30, 2013 to $10.9 million for the year ended June 30, 2014. Stock-based compensation increased as a result of vesting of previously granted share awards with a higher grant date fair value, and the granting of performance based restricted stock awards with shorter vesting periods than service based awards. Depreciation and amortization increased as a result of additional investment in capital equipment and patents.

Use and Economic Substance of Non-GAAP Financial Measures Used and Usefulness of Such Non-GAAP Financial Measures to Investors

We use Adjusted EBITDA as a supplemental measure of performance and believe this measure facilitates operating performance comparisons from period to period and company to company by factoring out potential differences caused by non-cash charges such as stock-based compensation and depreciation and amortization expense. Our management uses Adjusted EBITDA to analyze the underlying trends in our business, assess the performance of our core operations, establish operational goals and forecasts that are used to allocate resources and evaluate our performance period over period and in relation to our competitors’ operating results.

We believe that presenting Adjusted EBITDA provides investors greater transparency to the information used by our management for its financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by our management to evaluate and measure such performance. Adjusted EBITDA is also used to measure performance in our financial covenants as required by Silicon Valley Bank and Partners for Growth.

The following is an explanation of each of the items that management excluded from Adjusted EBITDA and the reasons for excluding each of these individual items:

Stock-based compensation.    We exclude stock-based compensation expense from our non-GAAP financial measures primarily because such expense, while constituting an ongoing and recurring expense, is not an expense that requires cash settlement. Our management also believes that excluding this item from our non-GAAP results is useful to investors to understand its impact on our operational performance, liquidity and ability to make additional investments in the Company, and it allows for greater transparency to certain line items in our financial statements.
Depreciation and amortization expense.    We exclude depreciation and amortization expense from our non-GAAP financial measures primarily because such expenses, while constituting ongoing and recurring expenses, are not expenses that require cash settlement and are not used by our management to assess the core profitability of our business operations. Our management also believes that excluding these items from our non-GAAP results is useful to investors to understand our operational performance, liquidity and ability to make additional investments in the Company.

34



Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in which We Compensate for these Limitations

Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for our financial results prepared in accordance with GAAP. Some of the limitations associated with our use of these non-GAAP financial measures are:

Items such as stock-based compensation do not directly affect our cash flow position; however, such items reflect economic costs to us and are not reflected in our Adjusted EBITDA and therefore these non-GAAP measures do not reflect the full economic effect of these items.
Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.
Our management exercises judgment in determining which types of charges or other items should be excluded from the non-GAAP financial measures we use.

We compensate for these limitations by relying primarily upon our GAAP results and using non-GAAP financial measures only supplementally.

LIQUIDITY AND CAPITAL RESOURCES

We had cash and cash equivalents of $126.6 million and $67.9 million at June 30, 2014 and 2013, respectively. During the year ended June 30, 2014, net cash used in operations amounted to $26.8 million. As of June 30, 2014, we had an accumulated deficit of $238.6 million. We have historically funded our operating losses primarily from the issuance of stock, convertible promissory notes, and debt.

Loan and Security Agreement with Silicon Valley Bank

On March 29, 2010, we entered into an amended and restated loan and security agreement with Silicon Valley Bank ("SVB"). The agreement was amended on December 27, 2011 to increase outstanding borrowings, amended on June 29, 2012 to modify financial covenants and reduce the interest rate and other fees, amended on May 10, 2013 to modify financial covenants and amended on June 26, 2014 to extend the line of credit to September 30, 2014 and reduce the interest rate. The agreement, as amended, includes a $12.0 million term loan and a $15.0 million line of credit. The terms of each of these loans are as follows:

The $12.0 million term loan had an initial interest rate of 8.0%, which could have been reduced to 7.0% based on the achievement of positive EBITDA for the trailing six month period. The term loan had a maturity of 36 months, with repayment terms that included interest only payments during the first six months, followed by 30 equal principal payments of $400,000 plus interest, and a final payment of $100,000 due at maturity. This term loan also included an acceleration provision that required us to pay the entire outstanding balance, plus a penalty ranging from 1.0% to 3.0% of the commitment amount, upon prepayment or the occurrence and continuance of an event of default. The balance outstanding on the term loan at June 30, 2014 and 2013 was $0 and $7.0 million, respectively, net of the unamortized discount associated with warrants issued to SVB in connection with the loan. The unamortized discount associated with warrants and other fees paid to the lender were amortized over the 36 months maturity period. See Note 6 to the consolidated financial statements for additional information. The term loan expired on June 30, 2014.

The $15.0 million line of credit expires on September 30, 2014 and has a floating interest rate equal to the Wall Street Journal's prime rate. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings on the line of credit are based on 85% of eligible accounts. Accounts receivable receipts are deposited into a lockbox account in the name of SVB. The line of credit is subject to non-use fees, annual fees, and cancellation fees. During the quarter ended December 31, 2013, we paid the remaining balance on the term loan with funds from the line of credit. The balance outstanding on the line of credit at June 30, 2014 and 2013 was $2.4 million and $0, respectively.

Borrowings from SVB are secured by all of our assets. The borrowings are subject to prepayment penalties and financial covenants, including maintaining certain liquidity and fixed charge coverage ratios. We were in compliance with all financial covenants as of June 30, 2014. Any non-compliance by under the terms of debt arrangements could result in an event of default under the SVB loan, which, if not cured, could result in the acceleration of this debt.

Loan and Security Agreement with Partners for Growth

On April 14, 2010, we entered into a loan and security agreement with PFG, as amended on August 23, 2011, December 27, 2011, June 30, 2012 and May 10, 2013. The amended agreement provides that PFG will make loans to us up to $5.0 million. The agreement has a maturity date of April 14, 2015. The loans bear interest at a floating per annum rate equal to 2.75% above SVB's prime rate, and such interest is payable monthly. The principal balance of and any accrued and unpaid interest on any notes are due on the maturity date and may not be prepaid at any time in whole or in part. As of June 30, 2014, PFG had converted all remaining loans.

At any time prior to the maturity date, PFG may at its option convert any outstanding loans into shares of our common stock at the applicable conversion price, which in each case equaled the ten-day volume weighted average price per share of our common stock prior to the issuance date of each note. We may also effect at any time a mandatory conversion of amounts, subject to certain terms, conditions and limitations provided in the agreement, including a requirement that the ten-day volume weighted average price of our common stock prior to the date of conversion is at least 15% greater than the conversion price. We may reduce the conversion price to a price that represents a 15% discount to the ten-day volume weighted average price of its common stock to satisfy this condition and effect a mandatory conversion. We recorded an (expense) benefit of $(61,000) and $0.4 million for the years ended June 30, 2014 and 2013 related to the change in fair value of the conversion options on all outstanding loans. This amount is a component of interest and other, net on the accompanying statement of operations. The balance outstanding under the loan and security agreement at June 30, 2014 and 2013 was $0 and $5.0 million, respectively, including the net unamortized premium. The net unamortized premium associated with the loan, a beneficial conversion feature, and other fees paid to the lender was recorded as a component of interest and other, net on the accompanying statement of operations.

During the years ended June 30, 2014 and 2013, PFG converted various loans, in accordance with the conversion terms set forth in the agreement. The non-cash conversion activity was as follows (in thousands, except share amounts):

Upon conversion of the PFG loans, we recorded a noncash write-off of $252,000 and $400,000 of premiums related to the loans during the years ended June 30, 2014 and 2013, respectively. Any loans are secured by certain of our assets, and the agreement contains customary covenants limiting our ability to, among other things, incur debt or liens, make certain investments and loans, effect certain redemptions of and declare and pay certain dividends on its stock, permit or suffer certain change of control transactions, dispose of collateral, or change the nature of its business. In addition, the PFG loan and security agreement contains financial covenants requiring us to maintain certain liquidity and fixed charge coverage ratios. We were in compliance with all financial covenants at June 30, 2014. If we do not comply with the various covenants, PFG may, subject to various customary cure rights, decline to provide additional loans, require amortization of any future loan over its remaining term, or require the immediate payment of all amounts outstanding under any future loan and foreclose on any or all collateral, depending on which financial covenants are not maintained.

Changes in Liquidity

Cash and Cash Equivalents.    Cash and cash equivalents was $126.6 million and $67.9 million at June 30, 2014 and 2013, respectively. The increase is primarily attributable to net cash provided by financing activities during the year ended June 30, 2014, partially offset by net cash used in operating and investing activities and payments of long term debt.

Operating Activities.    Net cash used in operating activities was $26.8 million, $10.8 million, and $11.3 million for the years ended June 30, 2014, 2013, and 2012, respectively. For the years ended June 30, 2014, 2013, and 2012, we had a net loss of $35.3 million, $24.0 million, and $16.8 million, respectively. Changes in working capital accounts also contributed to the net cash used in the years ended June 30, 2014, 2013, and 2012. Significant changes in working capital during these periods included:

Cash used in accounts receivable of $6.7 million, $1.3 million, and $0.4 million during the years ended June 30, 2014, 2013, and 2012, respectively. Cash used in accounts receivable is due to higher receivable balances from revenue growth, which has grown in each of the last three fiscal years.
Cash provided by (used in) inventories of $(6.6) million, $0.8 million, and $(1.2) million during the years ended June 30, 2014, 2013, and 2012, respectively. Cash used by inventories in fiscal 2014 was due to higher levels of inventory for future sales growth, including the CAD System commercial launch, as well as timing of inventory purchases and sales. Cash provided by (used in) inventories in fiscal 2013 and 2012 was primarily due to the timing of inventory purchases and sales.
Cash provided by (used in) prepaid expenses and other current assets of $(0.6) million, $0.9 million, and $(0.4) million during the years ended June 30, 2014, 2013, and 2012, respectively. Cash provided by (used in) prepaid expenses and other current assets was primarily due to payment timing of vendor deposits and other expenditures.
Cash provided by accounts payable of $4.6 million, $1.5 million, and $0.3 million during the years ended June 30, 2014, 2013, and 2012, respectively. Cash provided by accounts payable was primarily due to timing of purchases and vendor payments and overall increased levels of expenses.

37


Cash provided by accrued expenses and other liabilities of $4.5 million, $2.5 million, and $7,000 during the years ended June 30, 2014, 2013, and 2012, respectively. Cash provided by accrued expenses and other liabilities for fiscal 2014 was primarily related to increased incentive compensation related to performance above goals, higher accrued commissions due to increased sales, and higher payroll related expenses related to headcount and timing of payments. Cash provided by accrued expenses and other liabilities for fiscal 2013 and 2012 was primarily related to the timing and payment of accruals.

Investing Activities.    Net cash used in investing activities was $13.4 million, $2.5 million, and $1.0 million for the years ended June 30, 2014, 2013, and 2012, respectively. Cash used in investing activities resulted from investment in property, plant and equipment, and patents. In fiscal 2014, we paid $11.1 million towards the construction of our new corporate headquarters, including a $9.1 million escrow deposit. We expect the total cost of the building to be approximately $32 million.

Financing Activities.    Net cash provided by financing activities was $99.0 million, $45.6 million, and $26.7 million during the years ended June 30, 2014, 2013, and 2012, respectively. Cash provided by financing activities during these periods included:

Proceeds from the sale of common stock, net of issuance costs, of $84.4 million, $38.2 million, and $14.9 million during the years ended June 30, 2014, 2013 and 2012, respectively;
Exercise of stock options and warrants of $16.3 million, $5.9 million, and $4.4 million during the years ended June 30, 2014, 2013, and 2012, respectively;
Proceeds from long-term debt of $4.8 million, $4.5 million, and $7.9 million during the years ended June 30, 2014, 2013, and 2012, respectively; and
Employee stock purchase plan purchases of $3.4 million, $1.8 million, and $1.4 million during the years ended June 30, 2014, 2013, and 2012, respectively.

Cash used in financing activities in these periods included payments on long-term debt of $9.9 million, $4.8 million, and $1.9 million during the years ended June 30, 2014, 2013, and 2012, respectively.

Our future liquidity and capital requirements will be influenced by numerous factors, including the extent and duration of future operating losses, the level and timing of future sales and expenditures, the results and scope of ongoing research and product development programs, working capital required to support our sales growth, the receipt of and time required to obtain regulatory clearances and approvals, our sales and marketing programs, the continuing acceptance of our products in the marketplace, competing technologies and market and regulatory developments. As of June 30, 2014, we believe our current cash and cash equivalents and available debt will be sufficient to fund working capital requirements, capital expenditures (including the new corporate headquarters discussed below) and operations for the foreseeable future. We intend to retain any future earnings to support operations and to finance the growth and development of our business, and we do not anticipate paying any dividends in the foreseeable future. We may raise additional capital in the future, to fund acceleration of our current growth initiatives or additional growth opportunities, if we believe it will significantly enhance our value.

New Corporate Headquarters. On June 11, 2014, we entered into a Redevelopment Agreement, a Design-Build Contract, and a Development Services Agreement (as defined below) as well as various ancillary agreements related to the acquisition of real property located in New Brighton, Minnesota and the development of such property into our new corporate headquarters.
Pursuant to that certain Contract for Private Redevelopment by and among the City of New Brighton (the “City”), Ryan Companies US, Inc. (“Ryan”), and us, dated June 11, 2014 (the “Redevelopment Agreement”), we purchased approximately ten acres of real property from the City for a purchase price of $500,000. The City also granted us the option to purchase an additional 3.6 acres prior to May 31, 2021 pursuant to certain terms set forth in the Redevelopment Agreement.

Pursuant to that certain Design-Build Cost Plus Construction Contract by and between Ryan and us, dated June 11, 2014, we have contracted with Ryan to furnish all services, labor, materials, equipment, procurement services, project management and other duties and services necessary for construction of our new headquarters on the land purchased from the City. We expect to have construction substantially completed by March 1, 2015, and, pursuant to the Redevelopment Agreement discussed above, We have agreed with Ryan to complete construction by December 31, 2015. We anticipate that the total cost for the construction of the headquarters will be approximately $25 million, subject to certain increases or decreases if work is completed prior to or after March 1, 2015 or if changes are made to the project plans during construction. We will pay Ryan a fee of 3.85% of the cost of the work. We also anticipate that the total cost of furnishing, equipping and opening the headquarters will be approximately $7 million.

We also entered into a Development Services Agreement with Ryan, dated June 11, 2014, pursuant to which Ryan will perform certain development services to facilitate development of the project, including coordination with the City and overall coordinate of development strategy. We will pay Ryan a fee for the development services, which includes a sum equal to 3.25%

38


of the adjusted total project costs, payable at certain points in the construction process and a sum equal to 5% of the adjusted total project costs, payable upon substantial completion of the project, as well as reimbursement of certain expenses incurred by Ryan.

In connection with the agreements above, we were required to hold approximately $9.1 million in an escrow account which will be used to fund the final construction payments. The escrow is classified as construction in progress in property and equipment, net, on the consolidated balance sheet.

OFF-BALANCE SHEET ARRANGEMENTS

Since inception, we have not engaged in any off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

RECENT ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments in ASU 2013-11 require us to present an unrecognized tax benefit, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward or a similar tax loss or tax credit carryforward, unless the uncertain tax position is not available to reduce, or would not be used to reduce, the NOL or carryforward under the tax law in the same jurisdiction; otherwise, the unrecognized tax benefit should be presented as a gross liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for annual periods beginning after December 15, 2013 and should be applied to all unrecognized tax benefits that exist as of the effective date. Companies may choose to apply this guidance retrospectively to each prior reporting period presented. We do not anticipate a material impact on our consolidated financial statements upon adoption.

In May 2014, the FASB issued ASU 2014-09, “Revenue From Customers With Contracts.” The guidance requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 is effective for annual periods beginning after December 15, 2016, including interim periods within that reporting period, using one of two prescribed retrospective methods. Early adoption is not permitted. We are evaluating the impact of the amended revenue recognition guidance on our consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award
Provide That a Performance Target Could Be Achieved after the Requisite Service Period". The guidance requires that a
performance target that affects vesting and that could be achieved after the requisite service period should be treated as a
performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the

39


award. ASU 2014-12 is effective for annual and interim periods within the annual period beginning after December 15, 2015. We do not currently have share-based payment awards that fall within the scope of this standard and therefore we do not anticipate an impact on our consolidated financial statements upon adoption.

PRIVATE SECURITIES LITIGATION REFORM ACT

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Such “forward-looking” information is included in this Form 10-K and in other materials filed or to be filed by us with the Securities and Exchange Commission (as well as information included in oral statements or other written statements made or to be made by us). Forward-looking statements include all statements based on future expectations. This Form 10-K contains forward-looking statements that involve risks and uncertainties, including our expectations regarding the adoption of the PAD and CAD Systems through our direct sales force; our clinical trials and clinical evidence expectations; our plans to explore the acquisition of other product lines, technologies or companies and to continue to evaluate distribution agreements, licensing transactions and other strategic partnerships; use of proceeds from our public offering; future reimbursement for the PAD and CAD Systems; the possibility that we may sell internationally in the future and the timing for doing so; the future capacity of our credit facilities; the expectations regarding construction timing and expenses for our new corporate headquarters; the approval of our products in Japan, the granting of a CE Mark in Europe and the timing of such approvals; patent expiration expectations; our expectations regarding increased revenues; future efficiencies resulting from an increase in production costs; our expectations regarding improved fiscal year 2015 gross margins over fiscal 2014; an increase in selling, general and administrative expenses; research and development expenses being significantly above amounts incurred in fiscal 2014; no payment of dividends in the foreseeable future; and the sufficiency of our current and anticipated financial resources to fund operating expenses for at least the next 12 months and our expectations regarding raising additional capital. In some cases, you can identify forward-looking statements by the following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would,” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on our management’s beliefs and assumptions, which in turn are based on their interpretation of currently available information.

These statements involve known and unknown risks, uncertainties and other factors that may cause our results or our industry’s actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. These factors include regulatory developments in the U.S. and foreign countries; the experience of physicians regarding the effectiveness and reliability of the PAD and CAD Systems; the potential for unanticipated delays in enrolling medical centers and patients for clinical trials; actual clinical trial results; dependence on market growth; the reluctance of physicians to accept new products; the difficulty of successfully managing operating costs; FDA and similar foreign clearances and approvals; the impact of competitive products and pricing; approval of products for reimbursement and the level of reimbursement; unanticipated delays or costs related to construction of our new corporate headquarters; unanticipated developments affecting our estimates regarding expenses, future revenues and capital requirements; fluctuations in results and expenses based on new product introductions, sales mix, unanticipated warranty claims, and the timing of project expenditures; our inability to expand our sales and marketing organization and research and development efforts; our ability to obtain and maintain intellectual property protection for product candidates; our actual financial resources; general economic conditions; and those matters identified and discussed in Item 1A of this Form 10-K under “Risk Factors.”

You should read these risk factors and the other cautionary statements made in this Form 10-K as being applicable to all related forward-looking statements wherever they appear in this Form 10-K. We cannot assure you that the forward-looking statements in this Form 10-K will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. You should read this Form 10-K completely. Other than as required by law, we undertake no obligation to update these forward-looking statements, even though our situation may change in the future.
 
Item 7A.    Quantitative and Qualitative Disclosures About Market Risk.

The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk or availability. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and investments in a variety of marketable securities, including money market funds, U.S. government securities, and certain bank obligations. Our cash and cash equivalents as of June 30, 2014 include liquid money market accounts. Due to the short-term nature of these investments, we believe that there is no material exposure to interest rate risk.

Report of Independent Registered Public Accounting Firm


To the Board of Directors and Shareholders of Cardiovascular Systems, Inc.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of changes in shareholders’ equity and comprehensive loss and of cash flows present fairly, in all material respects, the financial position of Cardiovascular Systems, Inc. at June 30, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2014 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2014, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Company Description

Cardiovascular Systems, Inc. (the "Company") was incorporated as Replidyne, Inc. ("Replidyne") in Delaware in 2000. On February 25, 2009, Replidyne completed its reverse merger with Cardiovascular Systems, Inc., a Minnesota corporation incorporated in 1989 (“CSI-MN”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of November 3, 2008 (the “Merger Agreement”). Pursuant to the Merger Agreement, CSI-MN continued after the merger as the surviving corporation and a wholly-owned subsidiary of Replidyne. At the effective time of the merger, Replidyne changed its name to Cardiovascular Systems, Inc. (“CSI”) and CSI-MN merged with and into CSI, with CSI continuing after the merger as the surviving corporation. These transactions are referred to herein as the “merger.”

The Company develops, manufactures and markets devices for the treatment of vascular diseases. The Company’s peripheral arterial disease products, the Stealth 360°® PAD System, the Diamondback 360® PAD System, and the Predator 360°® PAD System, are catheter-based platforms capable of treating a broad range of plaque types, including calcified plaque, in leg arteries both above and below the knee and address many of the limitations associated with existing treatment alternatives. In October 2013, the Company received premarket approval (“PMA”) from the FDA to market the Diamondback 360® Coronary Orbital Atherectomy System (“OAS”) as a treatment for severely calcified coronary arteries. The Company began a controlled commercial launch of the Diamondback 360® Coronary OAS following receipt of PMA approval.

Principles of Consolidation

The consolidated balance sheets, statements of operations, changes in stockholders’ equity and comprehensive loss, and cash flows include the accounts of the Company and its wholly-owned subsidiary, after elimination of all intercompany transactions and accounts.

Cash and Cash Equivalents

The Company considers all money market funds and other investments purchased with an original maturity of three months or less to be cash and cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Customer credit terms are established prior to shipment with the general standard being net 30 days. Collateral or any other security to support payment of these receivables generally is not required. The Company maintains an allowance for doubtful accounts. This allowance is an estimate and is regularly evaluated by the Company for adequacy by taking into consideration factors such as past experience, credit quality of the customer base, age of the receivable balances, both individually and in the aggregate, and current economic conditions that may affect a customer’s ability to pay. Provisions for the allowance for doubtful accounts attributed to bad debt are recorded in general and administrative expenses. The following table shows the allowance for doubtful accounts activity (in thousands):

Inventories

Inventories are stated at the lower of cost or market with cost determined on a first-in, first-out (“FIFO”) method of valuation. The establishment of inventory allowances for excess and obsolete inventories is based on estimated exposure on specific inventory items.

Property and Equipment

Property and equipment is carried at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over estimated useful lives of five years for production equipment and furniture and fixtures; three years for computer equipment and software; and the shorter of their estimated useful lives or the lease term for leasehold improvements. Expenditures for maintenance and repairs and minor renewals and betterments which do not extend or improve the life of the respective assets are expensed as incurred. All other expenditures for renewals and betterments are capitalized. The assets and related depreciation accounts are adjusted for property retirements and disposals with the resulting gains or losses included in the consolidated statement of operations.

Patents

The capitalized costs incurred to obtain patents are amortized using the straight-line method over their remaining estimated lives. Patent amortization begins at the time of patent application approval, and does not exceed 20 years. The recoverability of capitalized patent costs is dependent upon the Company’s ability to derive revenue-producing products from such patents or the ultimate sale or licensing of such patent rights. Patents that are abandoned are written off at the time of abandonment.

Long-Lived Assets

The Company regularly evaluates the carrying value of long-lived assets for events or changes in circumstances that indicate that the carrying amount may not be recoverable or that the remaining estimated useful life should be changed. An impairment loss is recognized when the carrying amount of an asset exceeds the anticipated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. The amount of the impairment loss to be recorded, if any, is calculated by the excess of the asset’s carrying value over its fair value.

Operating Leases

The Company leases manufacturing and office space under operating lease agreements. One lease contains rent escalation clauses for which the lease expense is recognized on a straight-line basis over the lease term. Rent expense that is recognized but not yet paid is included in other liabilities on the consolidated balance sheets.

Revenue Recognition

The Company sells the majority of its products via direct shipment to hospitals or clinics. The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectability is reasonably assured. The Company records estimated sales returns, discounts and rebates as a reduction of net sales.

Costs related to products delivered are recognized in the period the revenue is recognized. Cost of goods sold consists primarily of raw materials, direct labor, and manufacturing overhead.

Income Taxes

Deferred income taxes are recorded to reflect the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts based on enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

Developing a provision for income taxes, including the effective tax rate and the analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets. The Company’s judgment and tax strategies are subject to audit by various taxing authorities.

Accounting guidance requires that accounting for uncertainty in income taxes is recognized in the financial statements. The guidance provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. The guidance also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Research and Development Expenses

Research and development expenses include costs associated with the design, development, testing, enhancement and regulatory approval of the Company’s products. Research and development expenses include employee compensation (including stock-based compensation), supplies and materials, consulting expenses, patent amortization, travel and facilities overhead. The Company also incurs significant expenses to operate clinical trials, including trial design, third-party fees, clinical site reimbursement, data management and travel expenses. Research and development expenses are expensed as incurred. Approved patent applications are capitalized and amortized using the straight-line method over their remaining estimated lives. Patent amortization begins at the time of patent application approval, and does not exceed 20 years.

Concentration of Credit Risk

Financial instruments that potentially expose the Company to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash balances primarily with one financial institution. These balances exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk in cash and cash equivalents.

Fair Value of Financial Instruments

Under the authoritative guidance for fair value measurements, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels defined as follows:

Level 1 Inputs — quoted prices in active markets for identical assets and liabilities
Level 2 Inputs — observable inputs other than quoted prices in active markets for identical assets and liabilities
Level 3 Inputs — unobservable inputs
 
The following table sets forth the fair value of the Company’s financial instruments that were measured on a recurring basis (in thousands):

The fair value of the debt conversion option is related to the loan and security agreement with Partners for Growth III. L.P. ("PFG") (described in Note 3) and is included as a component of debt conversion option and other assets on the balance sheet. The Monte Carlo option pricing model was used to determine the value of the debt conversion option and included various inputs such as expected volatility, stock price simulations, and assessed behavior of the Company and PFG based on those simulations. Based upon these inputs, the Company determined the conversion option to be a Level 3 investment. Significant increases (decreases) in any of these inputs in isolation would have resulted in a significantly higher (lower) fair value measurement. As of June 30, 2014, there was no balance for the debt conversion option asset as all of the associated convertible debt had been converted.

As of June 30, 2014, the Company believes that the carrying amounts of its other financial instruments, including accounts receivable, accounts payable and accrued liabilities, approximate their fair value due to the short-term maturities of these instruments.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Stock-Based Compensation

The Company has stock-based compensation plans, which includes stock options, nonvested share awards, and an employee stock purchase plan. Fair value of option awards is determined using option-pricing models, fair value of nonvested share awards with market conditions is determined using the Monte Carlo simulation, and fair value of nonvested share awards that vest based upon performance or time conditions is determined by the closing market price of the Company's stock on the date of grant, as determined by management and the board of directors. Stock-based compensation expense is recognized ratably over the requisite service period for the awards expected to vest.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments in ASU 2013-11 require companies to present an unrecognized tax benefit, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward or a similar tax loss or tax credit carryforward, unless the uncertain tax position is not available to reduce, or would not be used to reduce, the NOL or carryforward under the tax law in the same jurisdiction; otherwise, the unrecognized tax benefit should be presented as a gross liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for annual periods beginning after December 15, 2013 and should be applied to all unrecognized tax benefits that exist as of the effective date. Companies may choose to apply this guidance retrospectively to each prior reporting period presented. The Company does not anticipate a material impact on its consolidated financial statements upon adoption.

In May 2014, the FASB issued ASU 2014-09, “Revenue From Customers With Contracts.” The guidance requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 is effective for annual periods beginning after December 15, 2016, including interim periods within that reporting period, using one of two prescribed retrospective methods. Early adoption is not permitted. The Company is evaluating the impact of the amended revenue recognition guidance on its consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award
Provide That a Performance Target Could Be Achieved after the Requisite Service Period". The guidance requires that a
performance target that affects vesting and that could be achieved after the requisite service period should be treated as a
performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the
award. ASU 2014-12 is effective for annual and interim periods within the annual period beginning after December 15, 2015. The Company does not currently have share-based payment awards that fall within the scope of this standard therefore does not anticipate an impact on our consolidated financial statements upon adoption.

3. Debt

Loan and Security Agreement with Silicon Valley Bank

On March 29, 2010, the Company entered into an amended and restated loan and security agreement with Silicon Valley Bank ("SVB"). The agreement was amended on December 27, 2011 to increase outstanding borrowings, amended on June 29, 2012 to modify financial covenants and reduce the interest rate and other fees, amended on May 10, 2013 to modify financial covenants and amended on June 26, 2014 to extend the line of credit to September 30, 2014 and reduce the interest rate. The agreement, as amended, includes a $12,000 term loan and a $15,000 line of credit. The terms of each of these loans are as follows:

The $12,000 term loan had an initial interest rate of 8.0%, which could have been reduced to 7.0% based on the achievement of positive EBITDA for the trailing six month period. The term loan had a maturity of 36 months, with repayment terms that included interest only payments during the first six months, followed by 30 equal principal payments of $400 plus interest, and a final payment of $100 due at maturity. This term loan also included an acceleration provision that required the Company to pay the entire outstanding balance, plus a penalty ranging from 1.0% to 3.0% of the commitment amount, upon prepayment or the occurrence and continuance of an event of default. The balance outstanding on the term loan at June 30, 2014 and 2013 was $0 and $7,017, respectively, net of the unamortized discount associated with warrants issued to SVB in connection with the loan. The unamortized discount associated with warrants and other fees paid to the lender were amortized over the 36 months maturity period. See Note 6 for additional information. The term loan expired on June 30, 2014.

The $15,000 line of credit expires on September 30, 2014 and has a floating interest rate equal to the Wall Street Journal's prime rate. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings on the line of credit are based on 85% of eligible accounts. Accounts receivable receipts are deposited into a lockbox account in the name of SVB. The line of credit is subject to non-use fees, annual fees, and cancellation fees. During the quarter ended December 31, 2013, the Company paid the remaining balance on the term loan with funds from the line of credit. The balance outstanding on the line of credit at June 30, 2014 and 2013 was $2,400 and $0, respectively.

Borrowings from SVB are secured by all of the Company's assets. The borrowings are subject to prepayment penalties and financial covenants, including maintaining certain liquidity and fixed charge coverage ratios. The Company was in compliance with all financial covenants as of June 30, 2014. Any non-compliance by the Company under the terms of debt arrangements could result in an event of default under the SVB loan, which, if not cured, could result in the acceleration of this debt.

Loan and Security Agreement with Partners for Growth

On April 14, 2010, the Company entered into a loan and security agreement with PFG, as amended on August 23, 2011, December 27, 2011, June 30, 2012 and May 10, 2013. The amended agreement provides that PFG will make loans to the Company up to $5,000. The agreement has a maturity date of April 14, 2015. The loans bear interest at a floating per annum rate equal to 2.75% above SVB's prime rate, and such interest is payable monthly. The principal balance of and any accrued and unpaid interest on any notes are due on the maturity date and may not be prepaid by the Company at any time in whole or in part. As of June 30, 2014, PFG had converted all outstanding loans.


F-12

CARDIOVASCULAR SYSTEMS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

At any time prior to the maturity date, PFG may at its option convert any of the outstanding loans into shares of the Company's common stock at the applicable conversion price, which in each case equaled the ten-day volume weighted average price per share of the Company's common stock prior to the issuance date of each note. The Company may also effect at any time a mandatory conversion of amounts, subject to certain terms, conditions and limitations provided in the agreement, including a requirement that the ten-day volume weighted average price of the Company's common stock prior to the date of conversion is at least 15% greater than the conversion price. The Company may reduce the conversion price to a price that represents a 15% discount to the ten-day volume weighted average price of its common stock to satisfy this condition and effect a mandatory conversion. The Company recorded an (expense) benefit of $(61) and $370 for the years ended June 30, 2014 and 2013 related to the change in fair value of the conversion options on all outstanding loans. This amount is a component of interest and other, net on the accompanying statement of operations. The balance outstanding under the loan and security agreement at June 30, 2014 and 2013 was $0 and $5,000, respectively, including the net unamortized premium. The net unamortized premium associated with the loan, a beneficial conversion feature, and other fees paid to the lender was recorded as a component of interest and other, net on the accompanying statement of operations.

During the years ended June 30, 2014 and 2013, PFG converted various loans, in accordance with the conversion terms set forth in the agreement. The non-cash conversion activity was as follows (in thousands, except share amounts):

Upon conversion of the PFG loans, the Company recorded a noncash write-off of $252 and $400 of premiums related to the loans during the years ended June 30, 2014 and 2013, respectively. Any loans are secured by certain of the Company’s assets, and the agreement contains customary covenants limiting the Company’s ability to, among other things, incur debt or liens, make certain investments and loans, effect certain redemptions of and declare and pay certain dividends on its stock, permit or suffer certain change of control transactions, dispose of collateral, or change the nature of its business. In addition, the PFG loan and security agreement contains financial covenants requiring the Company to maintain certain liquidity and fixed charge coverage ratios. The Company was in compliance with all financial covenants at June 30, 2014. If the Company does not comply with the various covenants, PFG may, subject to various customary cure rights, decline to provide additional loans, require amortization of any future loan over its remaining term, or require the immediate payment of all amounts outstanding under any future loan and foreclose on any or all collateral, depending on which financial covenants are not maintained.

The Company has a 2007 Equity Incentive Plan (the “2007 Plan”), which was assumed from CSI-MN, under which options to purchase common stock and restricted stock awards have been granted to employees, directors and consultants at exercise prices determined by the board of directors; and also in connection with the merger the Company assumed options and restricted stock awards granted by CSI-MN under its 1991 Stock Option Plan (the “1991 Plan”) and 2003 Stock Option Plan (the “2003 Plan”) (the 2007 Plan, the 1991 Plan and the 2003 Plan collectively, the “Plans”). The 1991 Plan and 2003 Plan permitted the granting of incentive stock options and nonqualified options. A total of 485,250 shares of common stock were originally reserved for issuance under the 1991 Plan, but with the approval of the 2003 Plan no additional options were granted under it. A total of 2,458,600 shares of common stock were originally reserved for issuance under the 2003 Plan, but with the approval of the 2007 Plan no additional options will be granted under it.

The 2007 Plan originally allowed for the granting of up to 1,941,000 shares of common stock as approved by the board of directors in the form of nonqualified or incentive stock options, restricted stock awards, restricted stock unit awards, performance share awards, performance unit awards or stock appreciation rights to officers, directors, consultants and employees of the Company. The Plan was amended in February 2009 to increase the number of authorized shares to 2,509,969. Generally, options or shares granted under the 2007 Plan expire ten years from the date of grant and vest over three years. The amended 2007 Plan includes a renewal provision whereby the number of shares shall automatically be increased on the first day of each fiscal year ending on July 1, 2017, by the lesser of (i) 970,500 shares, (ii) 5% of the outstanding common shares on

such date, or (iii) a lesser amount determined by the board of directors. On July 1, 2014, the number of shares available for grant was increased by 834,134 under the 2007 Plan renewal provision, which was 2.7% of shares outstanding at June 30, 2014.

All options granted under the Plans become exercisable over periods established at the date of grant. The option exercise price is generally not less than the estimated fair market value of the Company’s common stock at the date of grant, as determined by the Company’s management and board of directors. In addition, the Company has granted nonqualified stock options to a director outside of the Plans.

As of June 30, 2014, all options were fully vested. An employee’s vested options must be exercised at or within 90 days of termination to avoid forfeiture. The Company determined the fair value of options using the Black-Scholes option pricing model. The estimated fair value of options, including the effect of estimated forfeitures, was recognized as expense on a straight-line basis over the options’ vesting periods. There were no options granted during the years ended June 30, 2014, 2013 or 2012.

The aggregate intrinsic value of a stock option award is the amount by which the market value of the underlying stock exceeds the exercise price of the award. The aggregate intrinsic value for vested and outstanding options at June 30, 2014, 2013 and 2012, was $19,377, $19,842 and $1,624, respectively. The total aggregate intrinsic value of options exercised during the years ended June 30, 2014, 2013 and 2012, was $16,848, $1,712, and $770, respectively. Cash received from option exercises was $7,664, $5,691 and $2,845 for the years ended June 30, 2014, 2013 and 2012, respectively. Shares supporting option exercises are sourced from new share issuances.

Restricted Stock Awards

The fair value of each restricted stock award was equal to the fair market value of the Company’s common stock at the date of grant. Vesting of restricted stock awards range from one to three years. The estimated fair value of restricted stock awards, including the effect of estimated forfeitures, is recognized on a straight-line basis over the restricted stock’s vesting period.

In August 2012, the Company granted performance based restricted stock awards to certain executives. The awards included grants of an aggregate of a maximum of 67,854 shares that vested based upon achievement of certain thresholds measuring total shareholder return during periods within fiscal 2013 compared to a pre-determined peer group of companies, and grants of an aggregate of a maximum of 67,854 shares that vested based upon achievement of certain thresholds measuring annual revenue growth during fiscal 2013 compared to a pre-determined peer group of companies. Both the total shareholder return and revenue growth performance measures exceeded the established thresholds for fiscal 2013.

In September 2013, the Company granted performance based restricted stock awards to certain executives. The awards included grants of an aggregate of a maximum of 53,566 shares that vest based upon achievement of certain thresholds measuring total shareholder return during periods within fiscal 2014 compared to a pre-determined peer group of companies, and grants of an

aggregate of a maximum of 53,566 shares that vest based upon achievement of certain thresholds measuring annual revenue growth during fiscal 2014 compared to a pre-determined peer group of companies. The total shareholder return performance exceeded threshold for fiscal 2014 and we expect the revenue growth to exceed the threshold for fiscal 2014 as well.

Total fair value of restricted stock that vested during fiscal 2014, 2013 and 2012 was $8,252, $5,006, and $3,625, respectively. Estimated pre-vesting forfeitures are considered in determining stock-based compensation expense. As of June 30, 2014, 2013 and 2012, the Company estimated its weighted average forfeiture rate at 17.5%, 11.5% and 11.6%, respectively. As of June 30, 2014, there was approximately $13,956 of total unrecognized compensation expense, net of the effect of estimated forfeitures, related to nonvested restricted stock awards which is expected to be recognized over a weighted-average period of 2.04 years.

Restricted Stock Units

The Company grants restricted stock units to members of the Board of Directors. Restricted stock units represent the right to receive payment in the form of shares of the Company’s common stock or in cash at the Company’s option. Restricted stock unit payments would occur within 30 days following the six month anniversary of the date that the director ceases to serve on the Board. The estimated fair value of restricted stock awards is recognized on a straight-line basis over the vesting period.

8.    Employee Stock Purchase Plan

The Company maintains an employee stock purchase plan ("ESPP"). The plan provides eligible employees the opportunity to acquire common stock in accordance with Section 423 of the Internal Revenue Code of 1986. Stock can be purchased each 6-month period per year (twice per year). The purchase price is equal to 85% of the lower of the price at the beginning or the end of the respective period. Employees purchased 149,839 shares at an average price of $22.50 per share during the year ended June 30, 2014. Shares reserved under the plan at June 30, 2014 totaled 30,870. The ESPP allows for an annual increase in reserved shares on each July 1 equal to the lesser of (i) 1% percent of the common shares outstanding, or (ii) 180,000 shares, provided that the Board of Directors may designate a smaller amount of shares to be reserved. On July 1, 2014, 90,000 shares were added to the ESPP.

The Company has established valuation allowances to fully offset its deferred tax assets due to the uncertainty about the Company’s ability to generate the future taxable income necessary to realize these deferred assets, particularly in light of the Company’s historical losses. The future use of net operating loss carryforwards is dependent on the Company attaining profitable operations, and may be limited in any one year under Internal Revenue Code Section 382 due to significant ownership changes, as defined under such Section, as a result of the Company’s equity financings. A summary of the valuation allowances are as follows (in thousands):

As of June 30, 2014 and 2013, the Company had federal tax NOL carryforwards of approximately $159,237 and $150,381, respectively. These NOL carryforwards are available to offset taxable income through 2034 and begin to expire in 2018. The Company also had various state NOL carryforwards available to offset future state taxable income. These state NOL carryforwards typically have the same expirations as the Company’s federal tax NOL carryforwards.

Our federal net operating losses at June 30, 2014 do not include $26,983 of income tax deductions in excess of previously recorded tax benefits related to stock compensation. These additional tax deductions are not included in the net operating losses referenced above since the related tax benefit will not be recognized until the deductions reduce our income tax payable. The tax benefit of these excess deductions will be reflected as a credit to additional paid in capital when recognized. Accordingly, our deferred tax assets are reported net of the excess tax deductions for stock compensation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

As of June 30, 2014 and 2013, the Company had approximately $3,624 and $3,171 of federal research and development credit carryforwards, respectively. As of June 30, 2014 and 2013, the Company had approximately $949 and $749 of state research and development credit carryforwards. The federal and state research and development credit carryforwards will begin to expire in 2026.

As required by FASB ASC Topic 740, “Income Taxes,” the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company recorded a liability relating to unrecognized tax benefits of $458 and $392 at June 30, 2014 and 2013, respectively. Due to the Company having a full valuation allowance, this liability has been netted against the deferred tax asset. The Company recognizes interest and penalties related to uncertain tax provisions as part of the provision for income taxes. The Company has not currently reserved for any interest or penalties for such reserves due to the Company being in an NOL position. The Company does not expect to recognize any benefits from the unrecognized tax benefits within the next twelve months.

The Company is subject to income taxes in the U.S. federal jurisdiction and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. The Company is potentially subject to income tax examinations by tax authorities for the tax years ended June 30, 2014, 2013, 2012, 2011, and 2010. The Company is not currently under examination by any taxing jurisdiction.

Construction of New Headquarters

On June 11, 2014, the Company entered into a Redevelopment Agreement, a Design-Build Contract, and a Development Services Agreement (as defined below) as well as various ancillary agreements related to the acquisition of real property located in New Brighton, Minnesota and the development of such property into the Company’s new corporate headquarters.
Pursuant to that certain Contract for Private Redevelopment by and among the City of New Brighton (the “City”), Ryan Companies US, Inc. (“Ryan”), and the Company, dated June 11, 2014 (the “Redevelopment Agreement”), the Company purchased approximately ten acres of real property from the City for a purchase price of $500. The City also granted the Company the option to purchase an additional 3.6 acres prior to May 31, 2021 pursuant to certain terms set forth in the Redevelopment Agreement.

Pursuant to that certain Design-Build Cost Plus Construction Contract by and between Ryan and the Company, dated June 11, 2014, the Company has contracted with Ryan to furnish all services, labor, materials, equipment, procurement services, project management and other duties and services necessary for construction of the Company’s new headquarters on the land purchased from the City. The Company and Ryan expect to have construction substantially completed by March 1, 2015, and, pursuant to the Redevelopment Agreement discussed above, Ryan and the Company have agreed to complete construction by December 31, 2015. The Company will pay Ryan a fee of 3.85% of the cost of the work.

The Company also entered into a Development Services Agreement with Ryan, dated June 11, 2014, pursuant to which Ryan will perform certain development services to facilitate development of the project, including coordination with the City and overall coordinate of development strategy. The Company will pay Ryan a fee for the development services, which includes a sum equal to 3.25% of the adjusted total project costs, payable at certain points in the construction process and a sum equal to 5% of the adjusted total project costs, payable upon substantial completion of the project, as well as reimbursement of certain expenses incurred by Ryan.

In connection with the agreements above, the Company was required to hold approximately $9,128 in an escrow account which will be used to fund the final construction payments. The escrow is classified as construction in progress in property and equipment, net, on the consolidated balance sheet.

11.    Employee Benefits

The Company offers a 401(k) plan to its employees. Eligible employees may authorize up to $18 of their annual compensation as a contribution to the plan, subject to Internal Revenue Service limitations. The plan also allows eligible employees over 50 years old to contribute an additional $6 subject to Internal Revenue Service limitations. All employees must be at least 21 years of age to participate in the plan. The Company did not provide any employer matching contributions for the years ended June 30, 2014, 2013, and 2012.
 
12.    Texas Production Facility

Effective on September 9, 2009, the Company entered into an agreement with the Pearland Economic Development Corporation (the “PEDC”) for the construction and lease of an approximately 46,000 square foot production facility located in Pearland, Texas. The facility primarily serves as an additional manufacturing location for the Company.

The Company and the PEDC entered into a Corporate Job Creation Agreement dated June 17, 2009, which was subsequently amended July 2, 2012. The Job Creation Agreement, as amended, provided the Company with $2,975 in net cash incentive funds. The Company believes it will be able to comply with the conditions specified in the amended agreement. The PEDC will provide the Company with an additional $425 of net cash incentive funds if: (1) the Company hires 125 full-time employee at the facility on or before June 30, 2015 and (2) maintains 125 employees at the facility through June 30, 2016. The Company had the opportunity to receive an additional $425 of net cash incentive funds upon hiring the 75th employee on or before March 31, 2014; however, the Company did not achieve this incentive.

In order to retain all of the cash incentives, the Company must maintain no fewer than 25 jobs at the Texas facility through June 30, 2015. Failure to meet this requirement will result in an obligation to make reimbursement payments to the PEDC as outlined in the amended agreement. The Company will not have any reimbursement requirements after June 30, 2015. As of June 30, 2014, the Company was in compliance with all minimum requirements under the amended agreement. The Company believes it will be able to comply with the conditions specified in the amended agreement.

CARDIOVASCULAR SYSTEMS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Job Creation Agreement, as amended, also provided the Company with a net $1,020 award, of which $510 was received from the PEDC and the remainder is funded through the Texas Enterprise Fund program associated with the State of Texas. As of June 30, 2014, $340 has been received and the remaining $170 will be provided upon the hiring of the 75th full-time employee at the facility. The grant from the State of Texas is subject to reimbursement if the Company fails to meet certain job creation targets through 2014 and maintain these positions through 2020. The Company reimbursed the State of Texas $46 during fiscal 2014 as it did not meet the target of hiring 75 employees at the facility by December 31, 2013.
  
The Company has presented the net cash incentive funds as a current and long-term liability on the balance sheet. The liabilities are reduced through the term of the agreement and recorded as an offset to expenditures incurred using a systematic methodology. As of June 30, 2014, the deferred grant incentive liabilities have been reduced by $3,659 in cumulative expenses, resulting in a remaining current liability of $59.
