SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



(1) Business — Spok Holdings, Inc. and its subsidiaries (collectively, "we", "Spok", or "the Company"), through our indirect wholly-owned subsidiary, Spok, Inc., is a comprehensive provider of critical communication solutions for enterprises. We are a leader in critical communication for healthcare, government, public safety and other industries. We deliver smart, reliable solutions to help protect the health, well-being and safety of people around the globe. Organizations worldwide rely on Spok for workflow improvement, secure texting, paging services, contact center optimization and public safety response. Our product offerings are capable of addressing a customer's mission critical communications needs.
(2) Preparation of Interim Financial Statements — Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Amounts shown on the condensed consolidated statements of income within the operating expense categories of cost of revenue; service, rental and maintenance; selling and marketing; and general and administrative are recorded exclusive of severance costs, and depreciation, amortization and accretion. These items are shown separately on the condensed consolidated statements of income within operating expenses. Foreign currency translation adjustments were deemed immaterial and consequently, no statements of comprehensive income are presented.
The financial information included herein, other than the condensed consolidated balance sheet as of December 31, 2015, is unaudited. The condensed consolidated balance sheet at December 31, 2015 has been derived from, but does not include, all the disclosures contained in the audited consolidated financial statements as of and for the year ended December 31, 2015. In management’s opinion, our unaudited condensed consolidated statements include all adjustments and accruals that are necessary for a fair presentation of the results of all interim periods reported herein and all such adjustments are of a normal, recurring nature.
These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 (the “2015 Annual Report”). The condensed consolidated statements of income for the interim periods presented are not necessarily indicative of the results that may be expected for a full year.
The accompanying condensed consolidated financial statements include our accounts and the accounts of our wholly-owned direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
The preparation of these condensed consolidated financial statements requires management to make judgments and estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results may differ from these estimates under different assumptions or conditions.
(3) Risks and Other Important Factors — See “Item 1A. Risk Factors” of Part II of this Quarterly Report on Form 10-Q (“Quarterly Report”) and "Item 1A. Risk Factors" of Part I of the 2015 Annual Report, which describes key risks associated with our operations and industry. 
(4) Recent and New Accounting Pronouncements — In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. Since the ASU was issued, the FASB has issued several changes including ASU No. 2015-14, in July 2015, which delayed the effective date and ASU No. 2016-08, in March 2016, which updated guidance related to principle versus agent considerations. Our effective date is January 1, 2018 and while early adoption to the original effective date of January 1, 2017 is permitted, we have elected not to early adopt.
ASU No. 2014-09 creates a five-step model that requires companies to exercise judgment when considering all relevant facts and circumstances in the determination of when and how revenue is recognized. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We have not selected a transition method. We continue to evaluate the potential impact from this ASU on our consolidated financial statements.
In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right of use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either financing or operating with classification affecting the pattern of expense recognition in the income statement.

5



SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


ASU No. 2016-02 will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. While we are still evaluating the impact of the potential new standard on our consolidated financial statements, we expect that upon adoption we will recognize ROU assets and lease liabilities and that the amounts could be material.
In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation Expense. The new standard is primarily focused on income taxes and the presentation of taxes related to stock compensation, but also provides a simpler method of accounting for forfeitures. An entity will now be able to make an entity-wide accounting policy election to either estimate the number of awards that are expected to be forfeited, as permissible under existing GAAP, or account for forfeitures as incurred. The purpose of this ASU was to reduce cost and complexity of the accounting related to share-based payment awards issued to employees for public and private companies.
ASU No. 2016-09 will be effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, and early adoption upon issuance of the ASU is permitted. We have adopted this new ASU to be effective January 1, 2016. As part of the adoption, we have made an accounting policy election to account for forfeitures as incurred rather than estimate the number of awards that are expected to be forfeited. The following summary provides further clarification of the transition approaches and the impact on the Company for each issue in ASU No. 2016-09 that requires a retrospective or modified retrospective approach:
For entities electing to account for forfeitures as they are incurred, a modified retrospective transition approach, with a cumulative-effect adjustment recognized in equity, is required for stock based compensation accounted for prior to the date on which the standard is adopted. We made the policy election to account for forfeitures as incurred and therefore, recorded a cumulative-effect adjustment in equity to account for this change. The overall impact to our consolidated financial statements is immaterial. Future forfeitures will be accounted for as they are incurred rather than estimating the number of awards that are expected to be forfeited at the time of grant.
A retrospective transition approach is required for classification of employee taxes paid on the Statement of Cash Flows when an employer withholds shares for tax-withholding purposes. In the first quarter of 2015, shares were withheld for tax-withholding purposes related to the payment of vested 2011 Long-Term Incentive Plan ("LTIP") awards. Previously, the withholdings were classified as an operating activity within our Statement of Cash Flows. We have retrospectively reclassified those withholdings as a financing activity and the total reclassification was $3.8 million.
There was no additional impact on our financial statements, resulting from the adoption of ASU No. 2016-09, that required a retrospective or modified retrospective approach. Any additional requirements under this ASU will be accounted for on a prospective basis.
(5) Inventory — Inventory of $2.0 million and $2.3 million at March 31, 2016 and December 31, 2015, respectively, consisted of third-party hardware and software held for resale. We value our inventory based on the lower of cost (determined using first-in, first-out) or current market value.
(6) Depreciation, Amortization and Accretion — The total depreciation, amortization and accretion expenses related primarily to property and equipment, amortizable intangible assets, and asset retirement obligations for the three months ended March 31, 2016 and 2015 and were $3.3 million and $3.7 million, respectively. The consolidated expenses consisted of the following for the periods stated:

(7) Goodwill and Amortizable Intangible Assets — Goodwill at March 31, 2016 and December 31, 2015 was $133.0 million. Goodwill is evaluated in the fourth quarter of each year and when events or circumstances suggest a potential impairment has occurred. There were no indicators of impairment as of March 31, 2016.
Amortizable intangible assets at March 31, 2016 primarily include customer related intangibles, technology based intangibles, contract based intangibles and marketing intangibles that resulted from our acquisition of Amcom Software, Inc. in 2011 and IMCO Technologies Corporation in 2012. Such intangibles are being amortized over periods ranging from two to ten years. The net consolidated balance of amortizable intangible assets consisted of the following:

Accounts payable decreased $0.9 million during the three months ended March 31, 2016 due to the timing related to the payment of invoices.

(9) Asset Retirement Obligations — We recognize liabilities and corresponding assets for future obligations associated with the retirement of assets. We have paging equipment assets, principally transmitters, which are located on leased locations. The underlying leases generally require the removal of equipment at the end of the lease term; therefore, a future obligation exists.
At January 1, 2016, we had recognized cumulative asset retirement costs of $3.6 million. During 2016, we have recorded nominal charges and as a result, the total cumulative asset retirement cost remains $3.6 million at March 31, 2016. The asset retirement cost additions during the three months ended March 31, 2016 increased paging equipment assets and are being depreciated over the related estimated lives of 51 to 57 months. The asset retirement costs and the corresponding liabilities that have been recorded to date generally relate to either current plans to consolidate networks or to the removal of assets at an estimated future terminal date.
The components of the changes in the asset retirement obligation liabilities were:

The balances above were included within accounts payable and accrued liabilities and other long-term liabilities, respectively, at March 31, 2016.
(10) Deferred Revenue — Deferred revenue at March 31, 2016 was $27.4 million for the current portion and $0.7 million for the non-current portion. Deferred revenue at December 31, 2015 was $27.0 million for the current portion and $0.7 million for the non-current portion. Deferred revenue primarily consists of unearned maintenance, software license and professional services revenue. Unearned maintenance revenue represents a contractual liability to provide maintenance support over a defined period of time for which payment has generally been received. Unearned software license and professional services revenue represents a contractual liability to provide professional services more substantive than post contract support for which not all payments have been received. We will recognize revenue when the service or software is provided or the delivery otherwise meets our revenue recognition criteria.
(11) Accrued Compensation and Benefits — Accrued compensation and benefits was $9.8 million at March 31, 2016 and $10.9 million at December 31, 2015. The decrease of $1.1 million reflects a three month accrual for the Short-Term Incentive Plan ("STIP") at March 31, 2016 versus a twelve month accrual at December 31, 2015 and the timing of payroll payments.
(12) Stockholders’ Equity and Stock Based Compensation — Our authorized capital stock consists of 75 million shares of common stock, par value $0.0001 per share, and 25 million shares of preferred stock, par value $0.0001 per share.
Changes in Stockholders’ Equity. Changes in stockholders’ equity for the three months ended March 31, 2016 consisted of:

The following table summarizes the activities under the 2012 Equity Incentive Award Plan (the "2012 Equity Plan") from January 1, 2016 through March 31, 2016:
 
Activity

2015 LTIP. On December 9, 2014, our Board of Directors adopted an LTIP (which provides for a 36 month vesting period) that included a stock component in the form of RSUs. Under this incentive program, RSUs will be granted to eligible employees annually and each annual grant will generally vest over a three year performance period. Our Board of Directors also approved that future cash dividends related to the RSUs will be set aside and paid in cash to each eligible employee when the RSUs are converted into shares of common stock. RSUs would be converted into shares of common stock on the earlier of a change in control of the Company (as defined in the 2015 LTIP) or on or after the third business day following the day that we file the Annual Report on Form 10-K with the SEC for the grant's final vesting year, but in no event later than December 31 of the year following the vesting date if the pre-established performance conditions are achieved. Any unvested RSUs awarded under the 2015 LTIP and the related cash dividends are forfeited if the participant terminates employment with the Company.
On January 2, 2015, our Board of Directors granted 254,777 RSUs to eligible employees under the 2012 Equity Plan for the 2015 LTIP pursuant to a Restricted Stock Unit Agreement with a grant date fair value of $4.4 million. Eligible employees have the opportunity to earn RSUs based upon the achievement of performance goals established by our Board of Directors for our consolidated revenue and operating cash flows (as defined by the Company) during the period of January 1, 2015 through December 31, 2017 (“the 2015-2017 performance period”), and continued employment with the Company. As of December 31, 2015, 242,468 shares related to this grant remained outstanding. For the three months ended March 31, 2016, 2,161 RSUs were forfeited by eligible employees who left the company. As of March 31, 2016 there were 240,307 RSUs outstanding relating to shares granted in January 2015. A total of $0.3 million was included in stock based compensation expense for the three months ended March 31, 2016 relating to this grant.
On January 28, 2016, our Board of Directors granted 227,082 RSUs to eligible employees under the 2012 Equity Plan for the 2015 LTIP pursuant to a Restricted Stock Unit Agreement with a grant date fair value of $3.8 million. Eligible employees have the opportunity to earn RSUs based upon the achievement of performance goals established by our Board of Directors for our consolidated revenue and operating cash flows (as defined by the Company) during the period of January 1, 2016 through December 31, 2018 (“the 2016-2018 performance period”), and continued employment with the Company. For the three months ended March 31, 2016, 2,046 RSUs were forfeited by eligible employees who left the company and 5,082 RSUs were granted to eligible employees who joined the company during the period. As of March 31, 2016 there were 230,118 RSUs outstanding relating to shares granted in January 2016. A total of $0.2 million was included in stock based compensation expense for the three months ended March 31, 2016 relating to this grant.

The increase in stock based compensation expense during the three months ended March 31, 2016, compared to the same period in 2015, was due primarily to the second RSU grant under the 2015 LTIP in January 2016. Each grant is amortized over the corresponding three year performance period beginning in the year of issuance.
Cash Dividends to Stockholders. The following table details our cash dividend payments made in 2016. Cash dividends paid as disclosed in the statements of cash flows for the three months ended March 31, 2016 and 2015 included previously declared cash dividends on shares of vested restricted stock issued to our non-executive directors and dividends related to vested RSUs issued to eligible employees. Cash dividends on RSUs and restricted stock have been accrued and are paid when the applicable vesting conditions are met. Accrued cash dividends on forfeited restricted stock and RSUs are also forfeited.

Additional Paid-in Capital. For the three months ended March 31, 2016, additional paid-in capital decreased by $4.2 million to $106.2 million at March 31, 2016 from $110.4 million at December 31, 2015. The decrease in the three months ended March 31, 2016 was due primarily to the repurchase of shares of common stock under the current stock repurchase program.
Net Income per Common Share. Basic net income per common share is computed on the basis of the weighted average common shares outstanding. Diluted net income per common share is computed on the basis of the weighted average common shares outstanding plus the effect of all potentially dilutive common shares including outstanding restricted stock and RSUs, which are treated as contingently issuable shares, using the “treasury stock” method.

(13) Income Taxes — We file a consolidated U.S. Federal income tax return and income tax returns in state, local and foreign jurisdictions as required.
At March 31, 2016, we had total deferred income tax assets of $127.5 million and a valuation allowance of $45.8 million resulting in an estimated recoverable amount of deferred income tax assets of $81.7 million. This reflects a change from the December 31, 2015 balance of deferred income tax assets of $129.8 million and a valuation allowance of $45.8 million resulting in an estimated recoverable amount of $84.0 million. The change reflects the expected usage of the deferred income tax assets based on estimated 2016 taxable income.
We consider both positive and negative evidence when evaluating the recoverability of our deferred income tax assets. The assessment is required to determine whether based on all available evidence, it is more likely than not (i.e., greater than a 50% probability) whether all or some portion of the deferred income tax assets will be realized in the future. During the three months ended March 31, 2016 we did not adjust the valuation allowance.
The anticipated effective income tax rate is expected to continue to differ from the Federal statutory rate of 35% primarily due to the effect of state income taxes, the effect of changes to the deferred income tax asset valuation allowance, permanent differences between book and taxable income and certain discrete items.
As of January 1 2016, we had approximately $282.1 million of Federal net operating losses (“NOLs”) available to offset future taxable income. Section 382 of the Internal Revenue Code limited NOLs, as of January 1, 2016, were $36.6 million which may be used at a rate of $6.1 million per year, and is included in the total Federal NOLs.
(14) Related Party Transactions — A member of our Board of Directors also serves as a Director for an entity that leases transmission tower sites to the Company. For the three months ended March 31, 2016 and 2015, we incurred site rent expenses of $1.0 million and $1.0 million, respectively, from the entity on which the individual serves as a Director. Site rent expenses are included in service, rental and maintenance expenses.
(15) Commitments and Contingencies — There have been no material changes during the three months ended March 31, 2016 to the commitments and contingencies previously reported in the 2015 Annual Report.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Forward-Looking Statements
This Quarterly Report contains forward-looking statements and information relating to Spok Holdings, Inc. and its subsidiaries ("we", “Spok” or the “Company”) that set forth anticipated results based on management’s current plans, known trends and assumptions. These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Statements that are predictive in nature, that depend upon or refer to future events or conditions, or that include words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “will,” “target,” “forecast” and similar expressions, as they relate to Spok are forward-looking statements.
Although these statements are based upon current plans, known trends and assumptions that management considers reasonable, they are subject to certain risks, uncertainties and assumptions, including but not limited to those discussed below and under the captions “Business,” “Management’s Discussion and Analysis of Financial Condition and Statements of Income (“MD&A”),” and “Part I – Item 1A – Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2015, filed with the United States Securities and Exchange Commission (the “SEC”) on February 25, 2016 (the “2015 Annual Report”). Should known or unknown risks or uncertainties materialize, known trends change, or underlying assumptions prove inaccurate, actual results or outcomes may differ materially from past results and those described herein as anticipated, believed, estimated, expected, intended, targeted or forecasted. Investors are cautioned not to place undue reliance on these forward-looking statements.
The Company undertakes no obligation to update forward-looking statements. Investors are advised to consult all further disclosures the Company makes in its subsequent reports on Form 10-Q and Form 8-K that it will file with the SEC. Also note that, in the risk factors disclosed in the Company’s 2015 Annual Report, the Company provides a cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to its business. These are factors that, individually or in the aggregate, could cause the Company’s actual results to differ materially from past results as well as those results that may be anticipated, believed, estimated, expected, intended, targeted or forecasted. It is not possible to predict or identify all such risk factors. Consequently, investors should not consider the risk factor discussion to be a complete discussion of all of the potential risks or uncertainties that could affect Spok's business, statement of income or financial condition, subsequent to the filing of this Quarterly Report.
Overview
The following MD&A is intended to help the reader understand the statements of income and financial position of Spok. The MD&A is provided as a supplement to, and should be read in conjunction with, our 2015 Annual Report and our unaudited condensed consolidated financial statements and accompanying notes. A reference to a “Note” in this section refers to the accompanying Unaudited Notes to the Condensed Consolidated Financial Statements.
Spok, acting through its indirect wholly-owned operating subsidiary, Spok, Inc., delivers smart, reliable solutions to help protect the health, well-being and safety of people around the globe. Organizations worldwide rely on Spok for workflow improvement, secure texting, paging services, contact center optimization and public safety response. When critical communications matter, Spok delivers. For the three months ended March 31, 2016 and 2015, wireless revenue represented approximately 62% and 64%, respectively and software revenue represented approximately 38% and 36%, respectively of our consolidated revenue.
Business
See Note 1 to our Unaudited Notes to Consolidated Financial Statements of Part I of this Quarterly Report on Form 10-Q ("Quarterly Report") and "Item 1. Business" of Part I of the 2015 Annual Report, which describes our business in further detail.
Revenue
We offer a focused suite of unified critical communication solutions that include call center operations, clinical alerting and notifications, one-way and advanced two-way wireless messaging services, mobile communications and public safety response.
We develop, sell and support enterprise-wide systems for healthcare, government, large enterprise and other organizations needing to automate, centralize and standardize their approach to critical communications. Our solutions can be found in prominent hospitals; large government agencies; leading public safety institutions, colleges and universities; large hotels, resorts and casinos; and well-known manufacturers. Our primary market has been the healthcare industry, particularly hospitals. We have identified hospitals with 200 or more beds as the primary targets for our software solutions.

Revenue generated by wireless messaging services (including voice mail, personalized greeting, message storage and retrieval) and equipment loss and/or maintenance protection to both one-way and two-way messaging subscribers is presented as wireless revenue in our statements of income. Revenue generated by the sale of our software solutions, which includes software license, professional services (installation, consulting and training), equipment (to be used in conjunction with the software) and post-contract support (on-going maintenance), is presented as software revenue in our statements of income. Our software is licensed to end users under an industry standard software license agreement.
Wireless Revenue
Our core offering includes subscriptions to one-way or two-way messaging services for a periodic (monthly, quarterly, semi-annual, or annual) service fee. This is generally based upon the type of service provided, the geographic area covered, the number of devices provided to the customer and the period of commitment. A subscriber to one-way messaging services may select coverage on a local, regional or nationwide basis to best meet their messaging needs. Two-way messaging is generally offered on a nationwide basis. In addition, subscribers either contract for a messaging device from us for an additional fixed monthly fee or they own a device, having purchased it either from us or from another vendor. We also sell devices to resellers who lease or resell devices to their subscribers and then sell messaging services utilizing our networks. We offer ancillary services, such as voicemail and equipment loss or maintenance protection, which help increase the monthly recurring revenue we receive along with these traditional messaging services.
Software Revenue
Software revenue consists of two primary components: operations revenue and maintenance revenue. Operations revenue consists of license revenue, professional services revenue, and equipment sales. Maintenance revenue is for ongoing support of a software application or equipment (typically for one year). We recognize equipment revenue when it is shipped or delivered to the customer depending on the delivery method of Free on Board ("FOB") shipping or FOB destination, respectively. License, professional services and maintenance revenue is recognized ratably over the longer of the period of professional services delivered to the customer or the contractual term of the maintenance agreement. If the period of delivery to the customer is not known, license and professional services revenue will be recognized when software and professional services are fully delivered to the customer and the maintenance revenue will be recognized ratably over the remaining contractual term of the agreement.
The following tables present the wireless and software revenue by key market segments for the periods stated and illustrate the relative significance of these market segments to our operations.

Revenue — Wireless
Our wireless revenue was $28.2 million and $30.7 million for the three months ended March 31, 2016 and 2015, respectively. The decrease in wireless revenue reflects the decrease in demand for our wireless services. Paging revenue consists primarily of recurring fees associated with the provision of messaging services and fees for paging devices and is net of a provision for service credits. Product and other revenue reflects system sales, the sale of devices and charges for paging devices that are not returned and are net of anticipated credits.

The demand for one-way and two-way messaging declined at each specified date and we believe demand will continue to decline for the foreseeable future. Demand for our services has also been impacted by the shift from narrow band wireless service offerings to broad band technology services.
As demand for one-way and two-way messaging has declined, we have developed or added service offerings such as Spok Mobile with a pager number in order to increase our revenue potential and mitigate the decline in our wireless revenue. We will continue to explore ways to innovate and provide customers the highest value possible. Software revenue is anticipated to increase, while the wireless revenue is expected to continue to decrease reflecting the changing technology expectations of our customer base.
Wireless revenue is generally based upon the number of units in service and the monthly charge per unit. The number of units in service changes based on subscribers added, referred to as gross placements, less subscriber cancellations, or disconnects. The net of gross placements and disconnects is commonly referred to as net gains or losses of units in service or the net disconnect rate. The absolute number of gross placements as well as the number of gross placements relative to average units in service in a period, referred to as the gross placement rate, is monitored on a monthly basis. Disconnects are also monitored on a monthly basis. The ratio of units disconnected in a period to average units in service for the same period, called the disconnect rate, is an indicator of our success at retaining subscribers, which is important in order to maintain recurring revenue and to control operating expenses.
The following table sets forth information on our units in service by account size at specified dates:

The other factor that contributes to revenue, in addition to the number of units in service, is the monthly charge per unit. As previously discussed, the monthly charge per unit is dependent on the subscriber’s service, extent of geographic coverage, whether the subscriber leases or owns the messaging device, and the number of units the customer has in the account. The ratio of revenue for a period to the average units in service, for the same period, commonly referred to as average revenue per unit or ARPU, is a key revenue measurement as it indicates whether charges for similar services and distribution channels are increasing or decreasing. ARPU by distribution channel and messaging service are monitored regularly.
The following table sets forth information on ARPU by account size for the periods stated:

While ARPU for similar services and distribution channels is indicative of changes in monthly charges and the revenue rate applicable to new subscribers, this measurement on a consolidated basis is affected by several factors, including the mix of units in service and the pricing of the various components of our services. We expect future sequential annual revenue to decline in line with recent trends. The decrease in consolidated ARPU for the quarter ended March 31, 2016 from the quarter ended March 31, 2015 was due to the change in composition of our customer base as the percentage of units in service attributable to larger customers continues to increase. These larger customers benefit from lower pricing associated with their larger number of units-in-service. We believe that without further price adjustments, ARPU will trend lower for the remainder of 2016. Price increases could mitigate, but not completely offset, the expected declines in both ARPU and revenue.
The following reflects the impact of subscribers and ARPU on the change in wireless revenue:

As previously discussed, demand for messaging services has declined over the past several years and we anticipate that it will continue to decline for the foreseeable future, which would result in reductions in wireless revenue due to the decreased number of subscribers and related units in service.
Revenue — Software
Our software revenue was $17.2 million and $17.4 million for the three months ended March 31, 2016 and 2015, respectively, which consisted of operations revenue (from licenses, professional services and equipment sales) and maintenance revenue.

The decrease in operations revenue primarily reflects a decrease in the number and size of projects completed in the first quarter of 2016 as compared to the same period in 2015. Starting in late 2015, the Company began a reorganization of the sales staff and related sales territories, which realigned territories and replaced lower performing sales employees with new staff. The Company is unable to predict the timing and impact of these changes on its software operations revenue in 2016. The increase in maintenance revenue reflects our continuing success in renewals of our maintenance support for existing software solutions and in maintenance support for sales of new solutions. The maintenance renewal rates for the three months ended March 31, 2016 and 2015 were in excess of 99%.
Our software revenue is dependent on the conversion of our software bookings into revenues. On a regular basis, we enter into contractual arrangements with our customers to provide software licenses, professional services, and equipment sales. In addition, we enter into contractual arrangements for maintenance with our customers on new solutions or renewals on existing solutions. These contractual arrangements are reported as bookings and represent future revenue. Bookings decreased by 14.8% for the three months ended March 31, 2016, compared to the same period in 2015. As noted above, starting in late 2015, the Company undertook a reorganization of the sales staff and related sales territories. As part of that reorganization, the Company is replacing lower performing sales employees with new staff. The Company is unable to predict the impact of this reorganization on the level of its software operations bookings in 2016.

Operating Expenses — Consolidated
We review the percentages of these operating expenses to revenue on a regular basis. Even though the operating expenses are classified as previously described, expense control and management are also performed by expense category. Approximately 70% of the operating expenses referred to above were incurred in payroll and related expenses, site and facility rent expenses and telecommunication expenses for both the three months ended March 31, 2016 and 2015.
Our largest expense, payroll and related expenses, includes wages, commissions, incentives, employee benefits and related taxes. On a monthly basis, we review the number of employees in major functional categories and the design and physical locations of functional groups to continuously improve efficiency, to simplify organizational structures, and to minimize the number of physical locations for the Company. We have 595 full-time equivalent employees (“FTEs”) at March 31, 2016, a decrease of 1.5% from 604 FTEs at March 31, 2015.
Site rent expenses for transmitter locations are largely dependent on our paging networks. We operate local, regional, and nationwide one-way and two-way paging networks. These networks each require locations on which to place transmitters, receivers, and antennae. Site rent expenses for transmitter locations are highly dependent on the number of transmitters, which in turn is dependent on the number of networks. In addition, these expenses generally do not vary directly with the number of subscribers or units in service, which is detrimental to our operating margins as wireless revenue declines. In order to reduce these expenses, we have an active program to consolidate the number of paging networks, and thus transmitter locations, which we refer to as network rationalization. We have reduced the number of active transmitters by 2.4% to 4,211 active transmitters at March 31, 2016 from 4,316 active transmitters at March 31, 2015.
Telecommunication expenses are incurred to interconnect our paging networks and to provide telephone numbers for customer use, points of contact for customer service, and connectivity among our offices. These expenses are dependent on the number of units in service, the number of customers we support and the number of office and network locations that we maintain. The number or duration of telephone calls to call centers may vary from period to period based on factors other than the number of units in service or customers, which could cause telecommunication expenses to vary.

As illustrated in the table above, cost of revenue for the three months ended March 31, 2016 decreased $0.8 million, or 9.0%, from the same period in 2015. This decrease was driven by a lower cost of sales, offset by an increase in payroll and related due to higher headcount.
Payroll and related — The increase of $0.5 million in payroll and related expenses was due primarily to an increase in the number of FTEs and higher average payroll and related expenses for professional services and maintenance support personnel.
Cost of sales — The decrease of $0.9 million in cost of sales expenses was primarily due to a decrease in the sale of third party software for the period and less use of third party resources for implementation related work.
Service, Rental and Maintenance. Service, rental and maintenance expenses consisted primarily of the following items:

As illustrated in the table above, service, rental and maintenance expenses for the three months ended March 31, 2016 remained relatively flat from the same period in 2015 due to the following significant variances:
Payroll and related — Payroll and related expenses were incurred largely for field technicians, their managers, in-house repair personnel, product development, product strategy and quality assurance personnel. The payroll and related expenses increased by $0.4 million for the quarter ended March 31, 2016 as compared to the quarter ended March 31, 2015 due to an increase of 9 FTEs and an increase in the average salary paid per employee. The change in headcount relates to an increase in the number of product development and strategy personnel. The company's Research and Development is included within service, rental and maintenance expenses. The Company is investing in the development of products in the areas of: 1) mobility, 2) a unified software platform, 3) nursing solutions and 4) alerting. Based on this emphasis we expect the number of FTEs to increase in this area.
Site rent — The decrease of $0.1 million in site rent expenses was primarily due to the rationalization of our networks, which has decreased the number of transmitters required to provide service to our customers. The reduction in transmitters has, in turn, reduced the number of lease locations. The number of active transmitters declined 2.4% from March 31, 2015 to March 31, 2016.

19



Telecommunications — The decrease of $0.1 million in telecommunication expenses was due to the consolidation of our networks. We believe continued reductions in these expenses will occur as our networks are managed, through the remainder of 2016, and as we reduce telephone circuit inventory.
Other — Other expenses consisted primarily of repairs and maintenance and outside services and reflect management of these expenses to meet our changing operations.
Selling and Marketing. Selling and marketing expenses consisted of the following items:

As indicated in the table above, selling and marketing expenses for the three months ended March 31, 2016 decreased $0.5 million, or 7.4%, from the same period in 2015.
Payroll and related The decrease of $0.3 million in payroll and related is primarily due to 12 fewer FTEs compared to the same period last year reflecting the reorganization of the sales staff, which includes the replacement of underperforming sales employees.
Commissions The decrease of $0.3 million in commission expense is due to lower software operations revenue compared to the same period in 2015.
Other — Other expenses consisted primarily of advertising, trade show, convention and related traveling expenses and reflect our focus on identifying sales opportunities.
The sales and marketing staff are all involved in selling our communication solutions domestically and internationally. These expenses support our efforts to maintain gross placements of units in service, which mitigate the impact of disconnects on our wireless revenue base, and to identify business opportunities for additional or future software sales. We have a centralized marketing function, which is focused on supporting our products and vertical sales efforts by strengthening our brand, generating sales leads and facilitating the sales process. These marketing functions are accomplished through targeted email campaigns, website development, social media, webinars, regional and national user conferences, monthly newsletters and participation at industry trade shows.

As illustrated in the table above, general and administrative expenses for the three months ended March 31, 2016 decreased $0.5 million, or 4.5%, from the same period in 2015 due to the following significant variances:
Payroll and related — Payroll and related expenses were incurred for employees in information technology, administrative operations, finance, human resources and executive management. Payroll and related expenses decreased by $0.5 million due to a reduction of 11 FTEs to 113 FTEs at March 31, 2016 from 124 FTEs at March 31, 2015 partially offset by a higher average salary per employee.
Stock based compensation increased $0.2 million due primarily to the 2015 LTIP grant on January 28, 2016 (See Note 12 to our Unaudited Notes to Consolidated Financial Statements in Part I of this Quarterly Report).
Outside services Outside service expenses consisted primarily of costs associated with professional services related to annual reporting, taxes and internal control compliance.
Taxes, licenses and permits Tax, license and permit expenses consisted primarily of property, franchise, gross receipts and transactional taxes.
Other Other expenses consisted primarily of bad debt, insurance, shipping costs, financial services, office rent and utilities.
Depreciation, Amortization and Accretion. Depreciation, amortization and accretion expenses were $3.3 million for the three months ended March 31, 2016 compared to $3.7 million for the same period in 2015. The decrease is primarily related to less capital expenditure purchases for pagers during three months ended March 31, 2016 as compared to the three months ended March 31, 2015, which impacted depreciation expense.
Income Tax Expense
Income Tax Expense. Income tax expense for the three months ended March 31, 2016 was $2.7 million, an increase of $0.3 million from the $2.4 million income tax expense for the same period in 2015. The increase in tax expense and the effective rate was caused primarily by two factors: a decrease in the State effective tax rate (from December 31, 2015) which results in a lower valuation of the DTAs, and foreign losses which were not recognized in computing the overall effective tax rate. Since we are uncertain whether foreign losses will provide a benefit at year end, we are required to exclude them from computing the effective tax rate at March 31, 2016.
The following is the effective tax rate reconciliation for the three months ended March 31, 2016 and 2015, respectively:

Liquidity and Capital Resources
Cash and Cash Equivalents
At March 31, 2016, we had cash and cash equivalents of $111.9 million. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of invested cash and cash in our operating accounts. The invested cash is invested in interest bearing funds managed by third-party financial institutions. These funds invest in direct obligations of the government of the United States. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurance that access to our invested cash and cash equivalents will not be impacted by adverse market conditions.
At any point in time, we have approximately $7.0 to $12.0 million in our operating accounts that are with third-party financial institutions. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts.

21



We intend to use our cash on hand to provide working capital, to support operations to invest in our business, and to return value to stockholders through cash dividends and repurchases of our common stock. We may also consider using cash to fund or complete opportunistic investments and acquisitions that we believe will provide a measure of growth or revenue stability while supporting our existing operations.
Overview
In the event that net cash provided by operating activities and cash on hand are not sufficient to meet future cash requirements, we may be required to reduce planned capital expenses, reduce or eliminate our cash dividends to stockholders, reduce or eliminate our common stock repurchase program, and/or sell assets or seek outside financing. We can provide no assurance that reductions in planned capital expenses or proceeds from asset sales would be sufficient to cover shortfalls in available cash or that outside financing would be available on acceptable terms. As of March 31, 2016, our available cash on hand was $111.9 million.
Based on current and anticipated levels of operations, we anticipate net cash provided by operating activities, together with the available cash on hand at March 31, 2016, should be adequate to meet our anticipated cash requirements for the foreseeable future.
The following table sets forth information on our net cash flows from operating, investing, and financing activities for the periods stated:

Net Cash Provided by Operating Activities. As discussed above, we are dependent on cash flows from operating activities to meet our cash requirements. Cash from operations varies depending on changes in various working capital items including deferred revenue, accounts payable, accounts receivable, prepaid expenses and various accrued expenses. Net cash provided by operating activities increased by $3.1 million for the three months ended March 31, 2016 compared to the same period in 2015 due primarily to a decrease in the amounts paid related to accrued compensation and benefits. Net cash for operating activities in 2015 was impacted by the timing of payroll payments and higher bonus payments as compared to 2016. The change in net cash provided by operating activities was $3.8 million higher prior to the reclassification of payroll taxes paid on vested RSUs.
Net Cash Used In Investing Activities. Net cash used in investing activities increased by $0.4 million for the three months ended March 31, 2016 compared to the same period in 2015 due primarily to an increase in capital expenses for property and equipment.
Net Cash Used In Financing Activities. Net cash used in financing activities decreased by $0.2 million for the three months ended March 31, 2016 compared to the same period in 2015 driven by a $4.4 million increase in common stock repurchases partially offset by $0.8 million reduction in cash dividends paid during the period. Cash dividends were higher in the first quarter of 2015 primarily due to the payment of accumulated cash dividends earned on vested RSUs from the 2011 LTIP. The remaining offset was related to the early adoption of ASU 2016-09 and the reclassification of employee stock based compensation for tax withholding purposes for the three months ended March 31, 2015 (See Note 4 to our Unaudited Notes to Consolidated Financial Statements in Part I of this Quarterly Report for further details regarding ASU No. 2016-09).
Future Cash Dividends to Stockholders. On April 27, 2016, our Board of Directors declared a regular quarterly cash dividend of $0.125 per share of common stock with a record date of May 23, 2016, and a payment date of June 24, 2016. This cash dividend of approximately $2.6 million will be paid from available cash on hand.
Common Stock Repurchase Program. In October 2015, the Board of Directors extended the common stock repurchase program through December 31, 2016. In extending the common stock repurchase plan the Board of Directors reset the purchase authority to $10.0 million with the repurchase authority to begin the earlier of January 4, 2016 or the completion of the existing common stock repurchase program. See Note 12 to our Unaudited Notes to Consolidated Financial Statements in Part I of this Quarterly Report for further details of our common stock repurchase program for the three months ended March 31, 2016.
Other. For 2016, the Board of Directors currently intends to return a minimum of $21.0 million to stockholders in a combination of dividends, common stock repurchases and/or special dividends, though the Board of Directors will continue to evaluate this amount throughout the year based on business and market conditions.

Commitments and Contingencies
Operating Leases. We have operating leases for office and transmitter locations. Substantially all of these leases have lease terms ranging from one month to five years. We continue to review our office and transmitter locations, and intend to replace, reduce or consolidate leases, where possible. Total rent expense under operating leases for the three months ended March 31, 2016 and 2015 was approximately $4.5 million and $4.7 million.
Off-Balance Sheet Arrangements. We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.
Commitments and Contingencies. See Note 15 to our Unaudited Notes to Consolidated Financial Statements in Part I of this Quarterly Report for further discussion on our commitments and contingencies.
Related Party Transactions
See Note 14 to our Unaudited Notes to Consolidated Financial Statements in Part I of this Quarterly Report for a discussion regarding our related party transactions.
Application of Critical Accounting Policies
The preceding discussion and analysis of financial condition and statement of income is based on our condensed consolidated financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of these condensed consolidated financial statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. On an on-going basis, we evaluate estimates and assumptions, including but not limited to those related to the impairment of long-lived assets and intangible assets subject to amortization and goodwill, accounts receivable, revenue recognition, asset retirement obligations, and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
There have been no changes to the critical accounting policies reported in the 2015 Annual Report that affect our significant judgments and estimates used in the preparation of our condensed consolidated financial statements.
Non-GAAP Financial Measures
We use a non-GAAP financial measure as a key element in determining performance for purposes of incentive compensation under our annual Short-Term Incentive Plan ("STIP") and LTIP. That non-GAAP financial measure is operating cash flow (“OCF”), defined as EBITDA less purchases of property and equipment. (EBITDA is defined as operating income plus depreciation, amortization and accretion, each determined in accordance with GAAP). Purchases of property and equipment are also determined in accordance with GAAP. For purposes of STIP and LTIP performance, OCF was as follows for the periods stated:

Item 3.  Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
As of March 31, 2016, we had no outstanding debt and no revolving credit facility.
Foreign Currency Exchange Rate Risk
We conduct a limited amount of business outside the United States. The financial impact of transactions billed in foreign currencies is immaterial to our financial results and, consequently, we do not have any material exposure to the risk of foreign currency exchange rate fluctuations.
Item 4.   Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management carried out an evaluation, as required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the participation of our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as of the end of our last fiscal quarter. Disclosure controls and procedures are defined under Rule 13a-15(e) under the Exchange Act as controls and other procedures of an issuer that are designed to ensure that the information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our principal executive officer and our principal financial officer have concluded that our disclosure controls and procedures were effective as of March 31, 2016.
Changes in Internal Control Over Financial Reporting
There were no changes made in the Company’s internal control over financial reporting during the three months ended March 31, 2016 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
