Cash is managed centrally and most cash generated by the Carve-Out Business was remitted to Microsemi. Such centralized cash management transactions relating to the Carve-Out Business are reflected through the Microsemi net investment in equity. Accordingly, none of the centrally managed cash at Microsemi’s corporate level have been reflected in the Carve-Out Business consolidated financial statements.

Cash Flows

Net cash provided from operating activities was $5.8 million and $3.0 million for the three month periods ended January 3, 2016 and December 28, 2014, respectively. Cash provided from operating activities for the years ended September 27, 2015, September 28, 2014 and September 29, 2013 were $13.5 million, $6.2 million and $9.2 million, respectively.

Net cash used in investing activities was $0.7 million and $0.4, million for the three month periods ended January 3, 2016 and December 28, 2014, respectively. Cash used in investing activities for the years ended September 27, 2015, September 28, 2014 and September 29, 2013 were $1.9 million, $1.9 million and $5.2 million, respectively.

Commitments, Contractual Obligations and Contingencies

The following is a schedule of the Carve-Out Business commitments and contractual obligations outstanding at December 31, 2015:

Off-Balance Sheet Arrangements

Other than lease commitments incurred in the normal course of business and certain indemnification provisions, the Carve-Out Business did not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity.

The Carve-Out Business did not have any majority-owned subsidiaries that are not consolidated in the financial statements. Additionally, the Carve-Out Business does not have an interest in, or relationships with, any special purpose entities.

Critical Accounting Policies and Significant Judgments and Estimates

Revenue Recognition

The Carve-Out Business primarily recognizes revenue from customers, including distributors, when title and risk of loss have passed to the customer provided that: 1) evidence of an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectability is reasonably assured. For substantially all sales, revenue is recognized, net of estimated returns and discounts, at the time the product is shipped.

The Carve-Out Business enters into distribution agreements that permit rights to limited stock rotations, returns, price protection, and volume purchase and other discounts. The Carve-Out Business provides an estimated allowance for these rights and records a corresponding reduction in revenue. The estimated allowance is based on several factors including past history and notification from customers of pending activity. Actual activity under such rights have been within management’s expectations.

Inventory Valuation

Inventories are stated at the lower cost, as determined using the first-in, first-out method, or market. Costs include materials, labor and manufacturing overhead. The carrying value of inventories is evaluated taking into account such factors as historical and anticipated future sales compared with quantities on hand and the price the Carve-Out Business expects to obtain for its products in their respective markets. The Carve-Out Business also evaluates the composition of its inventories to identify any slow-moving, excess or obsolete products. Additionally, inventory write-downs are made based on such judgments for any inventories that are identified as having a net realizable value less than their cost, which is further reduced by related selling expenses. The net realizable value of inventories for ongoing operations has generally been within management’s estimates.

Goodwill, Intangible Assets and Long-Lived Assets

The Carve-Out Business assesses the impairment of long-lived assets whenever events or changes in circumstances indicate their carrying value may not be recoverable from the undiscounted estimated future cash flows expected to result from their use. Judgments and assumptions may be required in identifying those events or changes in circumstances that may trigger impairment. Some of the factors considered include:

If events or circumstances indicate the carrying amount of a long-lived asset group may not be recoverable and the expected undiscounted future cash flows attributable to the asset group are less than the carrying value, an impairment loss equal to the excess of the carrying value of the assets within the asset group over their fair value is recorded. The appropriate asset group is determined based on the lowest level of largely independent cash inflows and outflows of the related assets. Depending on the nature of the primary assets in the asset group, fair value is estimated using one of several approaches including replacement cost, appraised values, market quotes or estimated expected future cash flows using a discount rate commensurate with the risk involved.

The Carve-Out Business accounts for goodwill on an impairment-only approach and amortizes intangible assets with definite useful lives over the benefit period, which approximates straight-line expense over the respective useful lives. Qualitative factors are assessed to determine whether it is more likely than not an indefinite-lived intangible such as goodwill is impaired as the basis for determining whether a qualitative impairment test is required. Definite-lived intangible assets are assessed for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be fully recoverable. Whenever the Carve-Out Business determines that there has been an impairment of goodwill or other intangible assets with indefinite lives, an impairment charge is recorded against earnings. The Carve-Out Business operates as one reporting unit and an impairment charge would equal the excess of the carrying value of goodwill in its one reporting unit over its then fair value. The identification of intangible assets and determination of the fair value and useful lives are subjective in nature and often involve the use of significant estimates and assumptions. The judgments made in determining the estimated useful lives assigned to each class of asset can significantly affect net income. The Carve-Out Business completed its most recent qualitative analysis during the fourth quarter of 2015 and noted no significant factors existed during the fiscal year to indicate it was more likely than not the fair value of the reporting unit is less than its carrying amount.

Income Taxes

In the Carve-Out Business consolidated financial statements, income tax expense and deferred tax balances have been calculated on a separate return basis, although the Carve-Out Business operations have historically been included in the tax returns filed by the respective Microsemi entities of which the Carve-Out Business is a part.

The Carve-Out Business recognizes tax benefits in its financial statements when its uncertain tax positions are more likely than not to be sustained upon audit. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The Carve-Out Business recognizes deferred tax assets for deductible

temporary differences, operating loss carryforwards and tax credit carryforwards. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.

The Carve-Out Business maintains an income taxes payable to/from account with Microsemi. The Carve-Out Business is deemed to settle current tax balances with the Microsemi tax paying entities in the respective jurisdictions. The Carve-Out Business’ current income tax balances are reflected as income taxes payable and settlements, which are deemed to occur in the year following incurrence, are reflected as changes in the net Microsemi investment in the consolidated balance sheets.

Cost Allocations

Management believes the assumptions and allocations underlying the consolidated financial statements are reasonable and appropriate. The expenses and cost allocations have been determined on a basis that Microsemi and the Carve-Out Business consider to be a reasonable reflection of the utilization of services provided or the benefit received by the Carve-Out Business during the periods presented.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 which provides guidance on how an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and on accounting for costs to obtain or fulfill a contract with a customer. The ASU also requires expanded disclosure regarding the nature, amount, timing and uncertainty of revenue that is recognized. In July 2015, the FASB decided to delay the effective date of this ASU by one year. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application permitted as of the original effective date. The Carve-Out Business is currently assessing the adoption and impact of this ASU on its consolidated financial position and results of operations.

In June 2014, the FASB issued ASU 2014-12 which provides guidance on how to account for share-based payment awards where the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, and early adoption is permitted. The Carve-Out Business is currently assessing the impact of this ASU on its consolidated financial position and results of operations.

In August 2014, the FASB issued ASU 2014-15 which provides guidance on management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or

within one year after the date that the financial statements are available to be issued when applicable) and to provide related footnote disclosures. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Carve-Out Business does not anticipate that adoption of this ASU will impact its consolidated financial position and results of operations.

In July 2015, the FASB issued ASU 2015-11 whose objective is to simplify the subsequent measurement of inventory by using only the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The Carve-Out Business does not anticipate that adoption of this ASU will impact its consolidated financial position and results of operations.

In September 2015, the FASB issued ASU 2015-16 whose objective is to simplify the accounting for measurement-period adjustments from a business combination. GAAP currently requires that during the measurement period, the acquirer retrospectively adjust provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill. The acquirer must revise comparative information for prior periods presented in financial statements as needed. ASU 2015-16 eliminates the requirement to retrospectively account for those adjustments. ASU 2015-16 is effective for annual periods beginning after December 15, 2016. The Carve-Out Business elected to early adopt this ASU retrospectively and adoption did not impact its consolidated financial position, results of operations or cash flows.

In November 2015, the FASB issued ASU 2015-17 whose objective is to simplify the presentation of deferred income tax assets and liabilities. ASU 2015-17 requires all deferred tax assets and liabilities, and any related valuation allowance, to be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Carve-Out Business does not anticipate that adoption of this ASU will impact its consolidated financial position and results of operations.
