Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business, Basis of Presentation and Accounting

1. DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND ACCOUNTING

Description of Business—M/A-COM Technology Solutions Holdings, Inc. (MACOM or the Company) was incorporated in Delaware on March 25, 2009. MACOM is a leading provider of high-performance analog semiconductor solutions that enable next-generation internet applications, the cloud connected apps economy, and the modern, networked battlefield across the radio frequency (RF), microwave and millimeterwave spectrum and photonic semiconductor products. Headquartered in Lowell, Massachusetts, MACOM has offices in North America, Europe, Asia and Australia.

The Company has one reportable operating segment which designs, develops, manufactures and markets semiconductors and modules.

Basis of Presentation—The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.

Under the Jumpstart Our Business Startups Act (JOBS Act), the Company qualifies as an emerging growth company. Accordingly, the Company has elected to avail itself of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. We expect to cease being an emerging growth company and become a large accelerated filer at the end of fiscal year 2015, which will, among other things, require us to fully comply with Section 404 of the Sarbanes-Oxley Act of 2002 including obtaining an auditor attestation of our internal controls.

The Company’s fiscal year ends on the Friday closest to the last day of September. For fiscal years in which there are 53 weeks, the first quarter reporting period includes 14 weeks. Fiscal year 2015 is 52 weeks in length and the three and nine months ended July 3, 2015 include 13 and 26 weeks, respectively. Fiscal year 2014 was 53 weeks in length and the three and nine months ended July 4, 2014 include 13 and 27 weeks, respectively. The accompanying condensed consolidated financial statements are referred to as “consolidated” for all periods presented.

On December 15, 2014, MACOM completed the acquisition of BinOptics Corporation (BinOptics), a supplier of high-performance photonic products (BinOptics Acquisition). The BinOptics Acquisition was accounted for as a purchase and the operations of BinOptics have been included in MACOM’s condensed consolidated financial statements since December 15, 2014, the date of acquisition.

MACOM acquired Nitronex, LLC (Nitronex) in a common-control business combination on February 13, 2014 (Nitronex Acquisition). Nitronex, a supplier of high-performance gallium nitride (GaN) semiconductors for RF, microwave and millimeterwave applications, was acquired by GaAs Labs, LLC (GaAs Labs) on June 25, 2012. Prior to the Nitronex Acquisition, GaAs Labs was a stockholder in MACOM, and GaAs Labs, Nitronex and MACOM were considered to be under common control from June 25, 2012 through February 13, 2014 due to a common controlling stockholder. The accompanying consolidated financial statements for the three months and nine months ended April 4, 2014, combine MACOM’s historical consolidated financial statements with the historical financial statements of Nitronex from January 3, 2014 through April 4, 2014 and September 28, 2013 through April 4, 2014, and have been presented in a manner similar to a pooling-of-interests to include the results of operations of each business since the date of common control.

On December 18, 2013, MACOM completed the acquisition of Mindspeed Technologies, Inc. (Mindspeed), a supplier of high-performance analog semiconductor solutions for communications infrastructure applications (Mindspeed Acquisition). The Mindspeed Acquisition was accounted for as a purchase, and the operations of Mindspeed have been included in MACOM’s consolidated financial statements since December 18, 2013, the date of acquisition.

These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 3, 2014, filed with the SEC on December 9, 2014.

In the opinion of management, the accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year 2015.

Principles of Consolidation—The accompanying consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Prior to the Nitronex Acquisition, MACOM and Nitronex did not have material intracompany transactions.

Use of Estimates—The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported amounts of revenue and expenses during the reporting periods, and the disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, the Company bases estimates and assumptions on historical experience, currently available information and various other factors that management believes to be reasonable under the circumstances. Actual results may differ materially from these estimates and assumptions.

Discontinued Operations—In the second quarter of fiscal year 2014, the Company sold assets of the non-core wireless business of Mindspeed and presented the divested businesses as assets held for sale as of the date of the Mindspeed Acquisition. The operating results of the business are reflected in discontinued operations.

Foreign Currency Translation and Remeasurement—The Company’s consolidated financial statements are presented in U.S. dollars. While the majority of the Company’s foreign operations use the U.S. dollar as the functional currency, the financial statements of the Company’s foreign operations for which the functional currency is not the U.S. dollar are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates (for assets and liabilities) and at average exchange rates (for revenue and expenses). The unrealized translation gains and losses on the net investment in these foreign operations are accumulated as a component of other comprehensive loss.

The financial statements of the Company’s foreign operations where the functional currency is the U.S. dollar, but where the underlying transactions are transacted in a different currency, are re-measured at the exchange rate in effect at the balance sheet date with respect to monetary assets and liabilities. Nonmonetary assets and liabilities, such as inventories and property and equipment and related statements of operations accounts, such as cost of revenue and depreciation, are remeasured at historical exchange rates. Revenue and expenses, other than cost of revenue, amortization and depreciation, are translated at the average exchange rate for the period in which the transaction occurred. The net gains (losses) on foreign currency remeasurement are reflected in selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The Company’s recognized net gains and losses on foreign exchange are included in selling, general and administrative expense and for all periods presented were immaterial.

Revenue Recognition—The Company recognizes revenue when: (i) persuasive evidence of an arrangement exists; (ii) delivery or services have been rendered; (iii) the price is fixed or determinable; and (iv) collectability is reasonably assured. The Company recognizes revenue with the transfer of title and risk of loss and provides for reserves for returns and other allowances.

The Company generally does not provide customers other than distributors the right to return product, with the exception of warranty related matters. Accordingly, the Company does not typically maintain a reserve for customers. Shipping and handling fees billed to customers are recorded as revenue while the related costs are classified as a component cost of revenue. The Company provides warranties for its products and accrues the cost of warranty claims in the period the related revenue is recorded.

Prior to fiscal 2015, the Company had concluded that it had insufficient information as well as limited experience in estimating the effect of the right of distributors to return product and price protection and, accordingly, used the sell through approach of revenue recognition. Under this approach, the Company would recognize revenue from sales after the distributor resold the product to its end customer (the sell through basis). After concluding an extensive three year study of distributor related transactions, the Company completed an evaluation of its revenue recognition policy and concluded that it was more appropriate to recognize revenue to distributors at the time of shipment to the distributor (sell-in basis). The Company believes it now has sufficient data to predict future price adjustments from distributors and has a basis of being able to reasonably estimate these future price adjustments.

On a consolidated basis, revenue from distribution customers impacted by the change in estimate accounts for approximately 10-15% of total consolidated revenue. Certain agreements with distribution customers provide for rights of return and compensation credits until such time as the Company’s products are sold by the distributors to their end customers. The Company has agreements with some distribution customers for various programs, including compensation, volume-based pricing, obsolete inventory, new products and stock rotation. Sales to these distribution customers, as well as the existence of compensation programs, are in accordance with terms set forth in written agreements with these distribution customers. In general, credits allowed under these programs are capped based upon individual distributor agreements. The Company records charges associated with these programs as a reduction of revenue at the time of sale with a corresponding adjustment to accounts receivable based upon historical activity. The Company’s policy is to use a 12 month rolling historical experience rate as well as an estimated general reserve percentage in order to estimate the necessary allowance to be recorded. The Company changed its revenue recognition policy from a sell through to a sell-in approach during the first fiscal quarter of 2015. The Company recognizes revenue when criteria for ASC 605-15-25 are met.

During the first fiscal quarter of 2015, the Company recorded corresponding adjustments related to this change in estimate to recognize previously deferred revenues. The net effect was an increase of $15.1 million, of which $12.4 million was from previously deferred revenue and $2.7 million was related to the change in distributor inventories. Additionally, the Company recognized the related deferred inventory costs of $4.7 million which resulted in a reduction to net loss of $8.5 million, or a reduction of $0.18 net loss per share when the change in estimate was recorded. During the three months ended July 3, 2015, this change in estimate resulted in decreased revenue of $1.3 million and a net loss of $0.6 million, or $0.01 loss per share, respectively. During the nine months ended July 3, 2015, this change in estimate resulted in revenue of $17.5 million and a reduction in net loss of $9.4 million, or a reduction of $0.18 net loss per share, respectively.

The Company also established a new reserve of $5.5 million during the first quarter of fiscal year 2015 which was increased to $6.2 million for the quarter ended July 3, 2015 related to future rebates and returns under various programs associated with our distributor agreements. The amount of this reserve is largely driven by the individual distribution agreements and the Company’s business strategy whereby the Company will invoice the distributor at “list price”. The Company expects to issue compensation credits consistent with the distributor agreements. The difference between the list price and distributor selling price will vary by product grouping consistent with historical trends and marketing strategies. Historically, 90 percent of the credits issued to distributors are based on “list price” credits and 10 percent of the credits were for product returns and stock rotation rights, based upon the 12 month rolling historical experience rate.

The table below shows the changes in gross and net distributor revenue and reserve balances associated with the change in estimate for the three and nine months ended July 3, 2015 (in millions):


	Three Months Ended									Nine Months Ended
	January 2, 2015			April 3, 2015			July 3, 2015			July 3, 2015
Gross revenue effect of one-time change in estimate (1)	$	17.0			—			—		$	17.0
Gross revenue effect associated with change in estimate (2)		3.6			4.7			(1.7	)		6.6

Total gross revenue resulting from change in estimate	$	20.6		$	4.7		$	(1.7	)	$	23.6

Net revenue effect of one-time change in estimate (3)		12.4			—			—			12.4
Net revenue effect associated with change in estimate (4)		2.7			3.7			(1.3	)		5.1

Total net revenue resulting from change in estimate	$	15.1		$	3.7		$	(1.3	)	$	17.5

Reserve for future returns and credits (5)	$	(5.5	)	$	(1.0	)	$	0.3		$	(6.2	)

(1)	This amount was recorded as deferred revenue as of October 2, 2014.

(2)	This amount represents the impact of the change in estimate associated with increases in distributor inventories as compared to the prior reporting period.

(3)	This amount represents the net revenue impact of the one-time change in estimate after applying the associated reserve for future credits and returns.

(4)	This amount represents the impact of the change in estimate associated with increases in distributor inventories as compared to the prior reporting period after applying the associated reserve for future credits and returns.

(5)	This amount reflects the change in the revenue reserve for future returns and credits. The balance as of July 3, 2015 is $6.2 million.

Property, Plant and Equipment—Property and equipment are stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major improvements that significantly extend the useful life of the assets are capitalized as additions to property and equipment.

Property and equipment are depreciated or amortized using the straight-line method over the following estimated useful lives:


Asset Classification		Estimated Useful Life In Years
Buildings and improvements		40
Machinery and equipment		2 – 7
Computer equipment and software		2 – 5
Furniture and fixtures		7 – 10
Leasehold improvements		Shorter of useful life or term of lease

Other Income—During the quarter ended July 3, 2015, we received $4.0 million related to a litigation settlement which is included in other income.

Recent Accounting Standards—In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASU 2014-08), which raises the threshold for disposals to qualify as discontinued operations. A discontinued operation is defined as: (1) a component of an entity or group of components that has been disposed of or classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results; or (2) an acquired business that is classified as held for sale on the acquisition date. ASU 2014-08 also requires additional disclosures regarding discontinued operations, as well as material disposals that do not meet the definition of discontinued operations. The application of this guidance is prospective from the date of adoption and applies only to disposals (or new classifications to held for sale) that have not been reported as discontinued operations in our previously issued financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires revenue recognition to depict the transfer of 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. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The amendments in the ASU can be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the update recognized at the date of the initial application along with additional disclosures. On July 9, 2015, the FASB voted to defer the effective date by one year to interim and annual reporting periods beginning after December 15, 2017, and permitted early adoption of the standard, but not for periods beginning on or before the original effective date of December 15, 2016. The Company has not yet selected a transition method and is currently evaluating the impact of ASU 2014-09.

In June 2014, the FASB issued ASU 2014-12—Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force) which addresses how to account for share-based performance awards including determining rendering service on the date the performance target is achieved. The Company is currently evaluating the impact of ASU 2014-12, which is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2015.

In February 2015, the FASB issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis. ASU 2015-02 address concerns regarding the current accounting for consolidation of certain legal entities. A reporting entity may apply the amendments in this Update using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. A reporting entity also may apply the amendments retrospectively. The Company is currently evaluating the impact of ASU 2015-02, which is effective for the Company in our fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015.

In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company is currently evaluating the impact of ASU 2015-03, which is effective for the Company in our fiscal years beginning after December 15, 2015, and interim periods within those fiscal years.

On December 15, 2014, MACOM completed the BinOptics Acquisition. In accordance with the Agreement and Plan of Merger, all of the outstanding equity interests (including outstanding warrants) of BinOptics were exchanged for aggregate consideration of approximately $208.4 million in cash. In addition the Company paid $14.6 million as part of a related retention escrow agreement designed to retain certain BinOptics employees. This $14.6 million was included in the terms of the purchase agreement and has been accounted for as a post-closing prepaid expense. The Company funded the BinOptics Acquisition with a combination of cash on hand and the incurrence of $100.0 million of additional borrowings under its existing Revolving Facility. For the nine months ended July 3, 2015, the Company recorded transaction costs of $4.2 million related to the BinOptics Acquisition.

The BinOptics Acquisition was accounted for as a purchase and the operations of BinOptics have been included in MACOM’s consolidated financial statements since the date of acquisition.

MACOM is recognizing BinOptics’ assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for BinOptics is being allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which is tax deductible.

The Company expects to finalize its allocation of purchase price within 12 months of December 15, 2014. The preliminary allocation of purchase price as of July 3, 2015, is as follows (in thousands):


	Original Allocation		Allocation Adjustments			July 3, 2015 Adjusted Allocation
Current assets	$	41,836	$	(15,373	)	$	26,463
Intangible assets		135,254		(554	)		134,700

Goodwill	$	84,980	$	3,035		$	88,015

The $15,762 of allocation adjustments shown above in the “Cash paid upon closing, net of cash acquired” caption consists of the following (in thousands):


	Cash paid upon closing, net of cash acquired
Original Allocation	$	224,114
Reclassification of prepaid compensation		(14,586	)
Reclassification of assumed capital lease debt		(1,044	)
Reclassification of escrow fees		(17	)

Allocation Adjustments		(15,762	)

Adjusted Allocations at July 3, 2015	$	208,352

The prepaid compensation item above is to correct the reclassification of employee retention escrow payment previously reported as a cash outflow from investing activities, to cash outflows from operating activities. The assumed capital lease debt item above is to show the gross capital lease debt assumed in the acquisition, not previously shown as part of purchase consideration.

The components of the acquired intangible assets on a preliminary basis were as follows (in thousands):


	Amount		Useful Lives (Years)
Developed technology	$	17,500	7
Customer relationships		117,200	10

	$	134,700

The overall weighted-average life of the identified intangible assets acquired in the BinOptics Acquisition is estimated to be 9.6 years and the assets are being amortized over their estimated useful lives based upon the pattern over which the Company expects to receive the economic benefit from these assets.

The purchase accounting is preliminary and subject to completion including the areas of taxation where a study of the potential utilization of acquired net operating losses is not yet complete, and certain fair value measurements, particularly the finalization of the valuation assessment of the acquired tangible and intangible assets. The adjustments arising from the completion of the outstanding matters may materially affect the preliminary purchase accounting and would be retroactively reflected in the financial statements as of July 3, 2015, and for the interim periods then ended.

The following is a summary of BinOptics revenue and earnings included in MACOM’s accompanying condensed consolidated statements of operations for the three and nine months ended July 3, 2015 (in thousands):


	Three Months Ended July 3, 2015		Nine Months Ended July 3, 2015
Revenue	$	20,186	$	39,393
Income (loss) before income taxes		1,980		(3,455	)

Unaudited Supplemental Pro Forma Data—The pro forma statements of operations data for the three and nine months ended July 3, 2015 and July 4, 2014, below, give effect to the BinOptics Acquisition, described above, as if it had occurred at September 27, 2013. These amounts have been calculated after applying MACOM’s accounting policies and adjusting the results of BinOptics to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets and additional interest expense on acquisition-related borrowings had been applied and incurred since September 27, 2013. The supplemental pro forma earnings for the three and nine months ended July 3, 2015 and July 4, 2014 were adjusted to exclude discontinued operations. This pro forma data is presented for informational purposes only and does not purport to be indicative of the Company’s future results of operations.


	Three Months Ended				Nine Months Ended
	July 3, 2015		July 4, 2014		July 3, 2015		July 4, 2014
Revenue	$	130,663	$	126,662	$	382,279	$	335,821
Net income (loss)		13,178		4,134		2,317		(34,817	)

The table above represents proforma net income (loss) which differs from the actual results due to adjustments related to inventory step-up and intangible amortization expense which were reflected in fiscal 2014.

Acquisition under Common Control—On February 13, 2014, MACOM acquired Nitronex, an entity under common control, through a cash payment of $26.1 million for all of the outstanding ownership interests of Nitronex. MACOM funded the Nitronex Acquisition through the use of available cash and borrowings under its revolving credit facility. The purchase price includes $3.9 million held on account by a third-party escrow agent pending any claims by MACOM in connection with general representation matters made by GaAs Labs in the transaction. The indemnification period expires in August 2015, at which point if no claims are made, all amounts will be paid to GaAs Labs.

Acquisition of Mindspeed Technologies, Inc.—On December 18, 2013, MACOM completed the acquisition of Mindspeed, a supplier of high-performance analog semiconductor solutions for communications infrastructure applications. The Company acquired Mindspeed to further its expansion into high-performance analog products.

MACOM completed the Mindspeed Acquisition through a cash tender offer (Offer) by Micro Merger Sub, Inc. (Merger Sub), a wholly-owned subsidiary of MACOM, for all of the outstanding shares of common stock, par value $0.01 per share, of Mindspeed (Shares) at a purchase price of $5.05 per share, net to the seller in cash, without interest, less any applicable withholding taxes (Offer Price). Immediately following the Offer, Merger Sub merged with and into Mindspeed, with Mindspeed surviving as a wholly-owned subsidiary of MACOM. At the effective time of the merger, each Share not acquired in the Offer (other than shares held by MACOM, Merger Sub and Mindspeed, and shares of restricted stock assumed by MACOM in the merger) was converted into the right to receive the Offer Price. MACOM funded the Mindspeed Acquisition through the use of available cash and borrowings under its revolving credit facility. The aggregate purchase price for the Shares, net of cash acquired, was $232.0 million and MACOM assumed $81.3 million of liabilities and incurred costs of $4.5 million that was expensed during fiscal year 2014.

The Mindspeed Acquisition was accounted for as a purchase and the operations of Mindspeed have been included in MACOM’s consolidated financial statements since the date of acquisition.

MACOM recognized assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for Mindspeed was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which is tax deductible.

The Company finalized the purchase price allocation of the Mindspeed Acquisition during the three months ended January 2, 2015. The final allocation of purchase price is as follows (in thousands):


	Amount
Current assets	$	50,612
Intangible assets		138,663
Deferred income taxes		92,881
Other assets		31,788

Total assets acquired		313,944

Liabilities assumed:
Current liabilities		35,270

Net assets acquired		232,632

Consideration:
Cash paid upon closing, net of cash acquired		232,028
Fair value of vested awards assumed in acquisition		785

Total consideration		232,813

Goodwill	$	181

In connection with the Mindspeed Acquisition, MACOM assumed all of the outstanding options and unvested restricted stock awards under Mindspeed’s equity plans and converted such options and stock awards into equivalent MACOM awards under the same general terms and conditions as were in existence with adjustments made to shares and exercise prices, if any, pursuant to a formula stipulated in the terms of the acquisition. The fair value of the assumed options and stock awards was $4.1 million, of which $0.8 million relates to vested stock options and has been included in the purchase consideration and the remainder relates to unvested stock options and stock awards, which will be expensed as the remaining services are provided.

The components of the acquired intangible assets were as follows (in thousands):


	Amount		Useful Lives (Years)
Developed technology	$	109,263	7
Customer relationships		11,430	10
In-process research and development		17,970	N/A

	$	138,663

The overall weighted-average life of the identified intangible assets acquired in the acquisition is estimated to be 7.3 years.

The following is a summary of Mindspeed’s revenue and earnings included in MACOM’s accompanying condensed consolidated statements of operations for the nine months ended July 4, 2014 (in thousands):


	Nine Months Ended July 4, 2014
Revenue	$	64,765
Loss from continuing operations before income taxes and restructuring charges		(18,534	)

Subsequent to closing the Mindspeed Acquisition, MACOM divested the wireless business of Mindspeed. The operations of the wireless business are included in discontinued operations through the date of sale. The Company completed the sale of the wireless business in February 2014. The accompanying consolidated statement of operations for the three and nine months ended July 4, 2014, includes the following operating results related to the divested wireless business (in thousands):

Unaudited Supplemental Pro Forma Data—The pro forma statements of operations data for the nine months ended July 4, 2014 below, give effect to the Mindspeed Acquisition, described above, as if it had occurred at September 27, 2013. These amounts have been calculated after applying MACOM’s accounting policies and adjusting the results of Mindspeed to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets and additional interest expense on acquisition-related borrowings had been applied and incurred since September 27, 2013. The supplemental pro forma earnings for the nine months ended July 4, 2014 were adjusted to exclude discontinued operations, as well as, certain other non-recurring items. This pro forma data is presented for informational purposes only and does not purport to be indicative of the Company’s future results of operations.


	Nine Months Ended July 4, 2014
Revenue	$	323,801
Net loss		(27,051	)

Other Acquisitions—In the fiscal fourth quarter of 2014, we acquired two businesses, I.K.E., Incorporated (IKE Micro) and Photonic Controls, LLC (Photonic Controls), for total cash consideration of $2.8 million. IKE Micro is a specialized build-to-print house based in New Hampshire. The primary purpose of the IKE Micro acquisition is to drive manufacturing cost reductions and further improve gross profit in the Company’s Optoelectronics business. Photonic Controls is a small design company based in Horseheads, New York, which specializes in photonic semiconductor development and system design. Its primary focus is to design silicon photonic chips for 100G/400G optical networks.

The assets acquired and liabilities assumed were recorded at their fair values and operating results were included in the financial statements from the date of acquisition. The preliminary purchase price allocation resulted in goodwill of $3.9 million and intangible assets, including manufacturing know-how and customer relationships, of $1.6 million recorded on the date of acquisition, which will be amortized over 7-10 years. Additionally, the Company recorded a contingent consideration liability of $0.8 million related to the acquisition of Photonic Controls which is included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheet as of October 3, 2014. The maximum possible payment of contingent purchase price is $1.5 million. Approximately $1.7 million of the goodwill resulting from these acquisitions is deductible for tax purposes. The purchase price allocation will be finalized in fiscal 2015 upon receipt of final information related to valuation of intangibles, and no allocation adjustments were recorded in the nine months ended July 3, 2015. The acquisitions were not material to the Company’s consolidated financial statements.

Investments—The Company determines the appropriate classification of its investments at the time of acquisition and re-evaluates such determination at each balance sheet date. The Company records at cost non-marketable equity investments where it does not have the ability to exercise significant influence or control and periodically reviews such investments for impairment.

During fiscal years 2014 and 2015, the Company made a minority investment of $0.3 million and $0.2 million in the convertible debt of a privately-held U.S. based company. The Company classified this investment as trading securities. (See Note 3).

During fiscal year 2014, the Company purchased a $5.0 million equity interest in a privately-held U.S. based company. The investment was accounted for utilizing the cost method and was included in Other Long-Term Assets in the Condensed Consolidated Balance Sheet. The Company determined that the equity investment contained embedded derivatives. The accounting treatment of derivative financial instruments requires that the Company record the fair value of the derivatives as of the inception date of the equity investment and to adjust the fair value as of each subsequent balance sheet date.

On May 11, 2015, the investee company was sold to a third party which provided the Company with information that the underlying value of the investment had been impaired at April 3, 2015. Accordingly, the Company recorded an impairment charge of $3.5 million which is included in Other Expense in the Condensed Consolidated Statement of Operations for the three months ended April 3, 2015 and the nine months ended July 3, 2015. The Company received $1.5 million in exchange for the equity investment during the three months ended July 3, 2015.

Fair Value Disclosures [Abstract]

Financial Instruments

3. FINANCIAL INSTRUMENTS

The Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

•

Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.

•

Level 3—Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by the Company.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at fair value on a recurring basis such as our financial instruments and derivatives. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three and nine months ended July 3, 2015.

As of July 3, 2015, the fair value of trading securities have been estimated to approximate cost. These estimates include significant judgments about potential future liquidity events and actual results could differ and could have an impact upon the values of the recorded financial instruments. Any changes in the estimated fair values of the financial instruments in the future will be reflected in the Company’s earnings and such changes could be material.

The fair values of the contingent consideration liabilities were estimated based upon a risk-adjusted present value of the probability-weighted expected payments by the Company. Specifically, the Company considered base, upside and downside scenarios for the operating metrics upon which the contingent payments are to be based. Probabilities were assigned to each scenario and the probability-weighted payments were discounted to present value using risk-adjusted discount rates. The maximum possible payment of contingent consideration is $1.5 million.

As of July 3, 2015, the fair value of the stock warrants has been estimated using a Black-Scholes option pricing model giving consideration to the quoted market price of the common stock on that date, an expected life of 5.5 years, expected volatility of 34.1% and risk free rate of 1.6%. Any significant change in these assumptions could have an impact on the value of the stock warrants.

The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of July 3, 2015 (in thousands):

Debt

6. DEBT

On September 26, 2013, and as amended November 5, 2013, the Company entered into an amended and restated loan agreement with a syndicate of lenders, which provided for a revolving credit facility of up to $300.0 million that was due to mature in September 2018 (Prior Facility). Borrowings under the revolving credit facility bore a variable interest rate based on either the lender’s prime rate or a LIBOR rate, plus an applicable margin. The revolving credit facility was secured by a first priority lien on substantially all of the Company’s assets and required compliance with certain financial and non-financial covenants. In connection with the Mindspeed and Nitronex acquisitions, MACOM borrowed an aggregate of $245.0 million of indebtedness on its Prior Facility.

On May 8, 2014, the Company refinanced its outstanding indebtedness under the Prior Facility and discharged its obligations thereunder by entering into a credit agreement (Credit Agreement) with Goldman Sachs Bank USA and a syndicate of lenders. Concurrent with the execution of the Credit Agreement, the Company terminated the Prior Facility and repaid the outstanding $245.0 million principal and interest due through draws on the Credit Agreement. Upon terminating the Prior Facility, previously deferred financing costs pertaining to that facility of $2.1 million were expensed as additional interest.

The Credit Agreement provides for term loans in an aggregate principal amount of $350.0 million, which mature in May 2021 (Term Loans) and a revolving credit facility of initially $100.0 million, which matures in May 2019 (Revolving Facility). In February 2015, the Company executed an amendment to the credit payment that increased the Company’s aggregate borrowing capacity under the Revolving Facility to $130.0 million. The Term Loans were issued with an original issue discount of 0.75%, which is being amortized over the term of the Term Loans using the straight-line method, which approximates the effective interest rate method. Borrowings under the Term Loans bear interest (payable quarterly) at: (i) for LIBOR loans, a rate per annum equal to the LIBOR rate (subject to a floor of 0.75%), plus an applicable margin of 3.75%, and (ii) for base rate loans, a rate per annum equal to the prime rate (subject to a floor of 1.75%), plus an applicable margin of 2.75%. Borrowings under the Revolving Facility bear interest (payable quarterly) at: (i) for LIBOR loans, a rate per annum equal to the LIBOR rate, plus an applicable margin in the range of 2.00% to 2.50% (based on the Company’s total net leverage ratio being within certain defined ranges); and (ii) for base rate loans, a rate per annum equal to the prime rate, plus an applicable margin in the range of 1.00% to 1.50% (based on the Company’s total net leverage ratio being within certain defined ranges). The Company also pays a quarterly unused line fee for the Revolving Facility in the range of 0.25% to 0.375% (based on the Company’s total net leverage ratio being within certain defined ranges) as well as overall agency fees. MACOM borrowed $100.0 million of indebtedness on its Revolving Facility in connection with the BinOptics Acquisition, which was paid down in full using net proceeds from a public offering of common stock the Company completed in February 2015. The Company has $130.0 million of borrowing capacity under the Revolving Facility as of July 3, 2015.

The Term Loans are payable in quarterly principal installments equal to 0.25% of the aggregate dollar amount of all Term Loans outstanding at the signing of the Credit Agreement, with the remainder due on the maturity date. In the event that the Company divests a business, the net cash proceeds of the divestment are generally to be applied to repayment of outstanding Term Loans except to the extent the Company reinvests such proceeds in assets useful for its business within 18 months of receiving the proceeds. To the extent the Company enters into a binding agreement to reinvest such proceeds within 18 months of receiving them, the Company has until the later of 18 months following its receipt of the proceeds and six months following the date of such agreement to complete the reinvestment.

At the signing of the Credit Agreement, the entire $350.0 million principal amount of the Term Loans was funded. The Term Loans and Revolving Facility are secured by a first priority lien on substantially all of the Company’s assets and provide that the Company must comply with certain financial and non-financial covenants. The Company was in compliance with all such covenants under the Credit Agreement as of July 3, 2015. The Company incurred $8.7 million in fees for the issuance of the Credit Agreement which were recorded as deferred financing costs and are being amortized over the life of Credit Agreement as interest expense. As of July 3, 2015, approximately $7.2 million of deferred financing costs remain unamortized.

As of July 3, 2015, the following remained outstanding on the Term Loans:


Principal balance	$	346,500
Unamortized discount		(2,187	)

Total Term Loans		344,313
Current portion		3,500

Long-term, less current portion	$	340,813

As of July 3, 2015, the minimum principal payments under the Term Loans in future fiscal years was as follows (in thousands):


2015 (rest of fiscal year)	$	875
2016		3,500
2017		3,500
2018		3,500
2019		3,500
2020		3,500
Thereafter		328,125

Total	$	346,500

The fair value of the Term Loans was estimated to be approximately $348.2 million as of July 3, 2015 and was determined using Level 3 inputs, including a quoted rate from a bank.

The trade name and in-process research and development (IPR&D) are indefinite-lived intangible assets. During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value to its carrying amount. If the carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Once an IPR&D project is complete, it becomes a definite long-lived intangible asset and is evaluated for impairment in accordance with the Company’s policy for long-lived assets.

Accumulated amortization for the acquired technology and customer relationships was $45.6 million and $16.7 million, respectively, as of July 3, 2015, and $23.2 million and $7.2 million, respectively, as of July 4, 2014.

In July 2013, the Company entered into a long term technology licensing and transfer agreement that calls for potential payments by the Company of up to $9.0 million through July 2016, based upon the achievement of specified milestones. Costs incurred in connection with the licensing and the transfer of the technology aggregated $8.2 million and $5.5 million as of July 3, 2015 and July 4, 2014, respectively, and were capitalized as incurred as acquired technology. Costs will be amortized to cost of revenue upon completion of the transfer, which is currently expected to be completed in fiscal year 2016.

Earnings Per Share [Abstract]

Income (Loss) Per Share

9. INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. The Company’s potential dilutive common shares consist of common shares issuable upon the exercise of warrants, stock options and vesting of restricted stock units. The dilutive effect of outstanding stock options is reflected in diluted earnings per share by application of the treasury stock method.

The following table sets forth the computation for basic and diluted net income (loss) per share of common stock (in thousands, except per share data):

Litigation—The Company is periodically subject to legal proceedings, claims and contingencies arising in the ordinary course of business. As of July 3, 2015, there was no other pending material litigation except as set forth below. Patent Suit Against Laird. We brought a patent infringement suit against Laird Technologies, Inc. (Laird) in the Federal District Court for the District of Delaware on February 11, 2014, seeking monetary damages and a permanent injunction. The suit alleged that Laird infringed on our United States Patent No. 6,272,349 (‘349 Patent), titled “Integrated Global Positioning System Receiver,” by making, using, selling, offering to sell or selling products incorporating an integrated global positioning receiver that include structure(s) recited in the ‘349 Patent, including global positioning system modules for automotive industry customers. The court entered a preliminary injunction against Laird on June 13, 2014. On April 15, 2015, the parties reached a confidential settlement agreement, filed a stipulated permanent injunction with the court that is similar in scope to the preliminary injunction, and filed a stipulated dismissal of all claims. The permanent injunction and dismissal were entered on April 21, 2015 by the court. Class Action Suit Against Mindspeed Technologies, Inc. On March 10, 2015, Philip Alvarez, a former employee of Mindspeed filed a putative class action lawsuit against Mindspeed in the Superior Court of California for the County of Orange. On April 24, 2015, the plaintiff filed a first amended complaint adding our subsidiary M/A-COM Technology Solutions Inc. as a defendant. The lawsuit alleges, among other things, that Mr. Alvarez and certain other employees who designed and manufactured hardware systems for Mindspeed or MACOM Technology Solutions Inc. between March 10, 2011 and the present were misclassified as exempt employees under California law. The lawsuit seeks recovery of alleged unpaid overtime wages, meal and rest period premiums, penalties and attorneys’ fees. We dispute the allegations of the lawsuit. On June 15, 2015, Mindspeed removed the action to the United States District Court for the Central District of California. The lawsuit is currently in the early stages of litigation. We intend to defend the lawsuit vigorously. With respect to the above and other legal proceedings, the Company has not been able to reasonably estimate the amount or range of any possible loss, and accordingly has not accrued or disclosed any related amounts of possible loss in the accompanying consolidated financial statements.

Share-Based Compensation

12. SHARE-BASED COMPENSATION

The Company has the following equity incentive plans: the Amended and Restated 2009 Stock Incentive Plan (2009 Plan), the 2012 Omnibus Incentive Plan (2012 Plan), the 2012 Employee Stock Purchase Plan (ESPP), the Mindspeed Technologies, Inc. 2013 Equity Incentive Plan (Mindspeed 2013 Plan), the Mindspeed Technologies, Inc. 2003 Long-Term Incentives Plan (Mindspeed 2003 Plan) and the Mindspeed Technologies, Inc. Directors Stock Plan (Mindspeed Directors Plan).

Upon the closing of the Company’s initial public offering, all shares that were reserved under the 2009 Plan but not awarded were assumed by the 2012 Plan. No additional awards will be made under the 2009 Plan. Under the 2012 Plan, the Company has the ability to issue incentive stock options (ISOs), non-statutory stock options (NSOs), stock appreciation rights, restricted stock, restricted stock units (RSUs), performance units, performance shares and other equity-based awards to employees, directors and outside consultants. The ISOs and NSOs must be granted at a price per share less than the fair value of our common stock on the date of grant. Options granted to date generally vest over a four-year period with 25% vesting at the end of one year and the remaining vest monthly thereafter. Certain of the share-based awards granted and outstanding as of July 3, 2015, are subject to accelerated vesting upon a sale of the Company or similar changes in control. Options granted generally are exercisable up to 10 years. In fiscal year 2012, the Company began granting RSUs, which generally vest annually over one to five years. As of July 3, 2015, the Company had 9.1 million shares available for future grants under the 2012 Plan.

The Mindspeed 2013 Plan, the Mindspeed 2003 Plan, the Mindspeed Directors Plan and certain inducement equity grants (collectively, the Mindspeed Plans) were assumed by the Company in connection with the Mindspeed Acquisition. No additional equity awards will be made under the Mindspeed Plans.

The following table presents the effects of share-based compensation expense related to share-based awards to employees and non-employees in the Company’s condensed consolidated statements of operations during the periods presented (in thousands):

Stock Options

A summary of stock option activity for the nine months ended July 3, 2015, is as follows (in thousands, except per share amounts):


	Number of Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value
Outstanding-October 3, 2014		948		$	11.73		6.6	$	10,015

Options vested and expected to vest as of July 3, 2015		819		$	16.54		7.0	$	16,593

Options vested and exercisable as of July 3, 2015		665		$	12.49		6.3	$	16,196

Aggregate intrinsic value represents the difference between the Company’s closing stock price on July 3, 2015 and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was $3.6 million for the nine months ended July 3, 2015.

In April 2014, the Company granted stock options as to 405,000 shares of common stock with a grant date fair value of $3.5 million that are subject to vesting only upon the market price of the Company’s underlying public stock closing above a certain price target within ten years of the grant date. Due to the market condition upon which vesting is based, the fair value of the awards was estimated using a Monte Carlo simulation model. Compensation cost is recognized regardless of the number of awards that are earned based on the market condition. Compensation cost is recognized on a straight-line basis over the estimated service period of three years. In the event that the Company’s common stock achieves the target price of $32.55 per share prior to the end of the estimated service period, any remaining unamortized compensation cost will be recognized. These options are included in the table and other information above.

On January 23, 2015, the Company’s common stock closed at a price of $34.79 per share, exceeding the target price of $32.55 per share, which resulted in the recognition of approximately $2.5 million of compensation expense in the current quarter. Accordingly, as of July 3, 2015, the majority of unrecognized compensation cost, adjusted for estimated forfeitures, related to unvested stock options was recognized during the quarter.

On April 22, 2015 and May 5, 2015, the Company granted 225,000 performance-based stock options for shares of common stock with an aggregate grant date fair value of $2.0 million that are subject to vesting based on a service and individual performance targets. The Company used the Black-Scholes valuation model for estimating the fair value on the date of grant of $8.97 and $8.45 per option share on April 22, 2015 and May 5, 2015, respectively. The fair value of stock option awards is affected by valuation assumptions, including volatility, the Company’s stock price, expected term of the option, risk-free interest rate and expected dividends.

The weighted-average assumptions used for calculating the fair value of stock options granted is as follows:


Risk-free interest rate	1.2	%
Expected term (years)	4
Expected volatility	30.8	%
Expected dividends	—	%

The performance-based stock options described above will vest and become exercisable in full if certain pre-established revenue and non-GAAP gross margin targets are met or exceeded in any period of four consecutive fiscal quarters completed during the term of the options. The stock options have a term of seven years, assuming continued employment with or services to the Company, and have an average exercise price of $34.10 and equal to the closing price of the Company’s common stock on the date of grant.

Restricted Stock Awards and Units

A summary of restricted stock and restricted stock unit activity for the nine months ended July 3, 2015, is as follows (in thousands):


	Number of Shares			Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value
Unvested-October 3, 2014		1,720			2.6	$	37,203

Shares expected to vest-July 3, 2015		1,505			1.5	$	55,195

Performance-Based Restricted Stock Unit Awards (PRSU)

On April 22, 2015 and May 5, 2015, the Company issued performance-based RSUs which were divided into three equal tranches with one tranche based on the Company’s non-GAAP earnings per share (EPS) growth during fiscal year 2015, one tranche based on non-GAAP EPS growth during fiscal years 2015-2016 and one tranche based on non-GAAP EPS growth during fiscal years 2015-2017. A participant may earn between 0% to 300% of the targeted shares for each tranche based on actual performance, and a straight-line interpolation will be applied for achievement between the specified performance ranges. Once earned, the performance-based RSUs will be settled in shares of the Company’s common stock, assuming continued employment with or services to the Company through the vest date of May 15th following each tranches performance criteria being met at period end.

A summary of PRSU activity during the nine months ended July 3, 2015 is as follows:


	Non-vested Performance-based Restricted Stock Units		Weighted-Average Grant-Date Fair Value per PRSU
Non-vested shares at October 3, 2014		—		—
Granted		83,954	$	34.39
Change due to performance condition achievement		251,862	$	34.39
Vested		—		—
Forfeited		—		—

Non-vested shares at July 3, 2015		335,816	$	34.39

The total fair value of restricted stock awards with time-based and performance vesting was $8.6 million for the nine months ended July 3, 2015. As of July 3, 2015, total unrecognized compensation cost, adjusted for estimated forfeitures, related to restricted stock and units with time-based and performance vesting was $39.1 million, which is expected to be recognized over the next 3.6 years.

On April 22, 2015, the Company approved an amended and restated Change in Control Plan to exclude certain performance-based options and to increase the percentage by which outstanding performance-based equity awards, other than those specifically excluded) will be deemed earned in the event of a change in control, from 100% of target to 200% of targeted shares. Other share-based awards granted and outstanding as of July 3, 2015, are subject to accelerated vesting upon a sale of the Company or similar changes in control. The financial impact of any modifications to share-based awards during the periods presented was immaterial.

Employee Stock Purchase Plan (ESPP)

Under the Company’s ESPP plan eligible employees are allowed to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. As of July 3, 2015, total prorated compensation cost related to the ESPP has been recognized.

Income Taxes	9 Months Ended
Income Taxes	Jul. 03, 2015
Income Tax Disclosure [Abstract]
Income Taxes	13. INCOME TAXES The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax and may also be subject to current U.S. income tax. For interim periods, the Company records a tax provision or benefit based upon the estimated effective tax rate expected for the full fiscal year, adjusted for material discrete taxation matters arising during the interim periods. The difference between the U.S. federal statutory income tax rate of 35% and the Company’s effective income tax rates for the three and nine months ended July 3, 2015 and July 4, 2014, was primarily impacted in all periods by changes in fair values of the common stock warrant liability which is neither deductible nor taxable for tax purposes, income taxed in foreign jurisdictions at generally lower tax rates and non-deductible compensation, offset by U.S. state income taxes. For the nine months ended July 3, 2015, the rate was also impacted by non-deductible merger expenses resulting from the BinOptics Acquisition. The balance of the unrecognized tax benefit as of July 3, 2015 and October 3, 2014 was $1.7 million and includes a $1.4 million reduction in current deferred tax assets and a $0.3 million increase in other long-term liabilities in the accompanying consolidated balance sheets. The entire balance of unrecognized tax benefits, if recognized, will reduce income tax expense. It is the Company’s policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the quarter ending July 3, 2015, the Company did not make any payment of tax-related interest and penalties. There was nothing accrued in the consolidated balance sheets for the payment of such interest and penalties at July 3, 2015 as the remaining unrecognized tax benefits would only serve to reduce the Company’s current federal and state NOL carryforwards, if ultimately recognized. As disclosed in Note 2 - Acquisition of BinOptics Corporation, the purchase accounting related to the acquisition of BinOptics includes preliminary income tax amounts subject to revision upon obtaining and analyzing all information. At the closing of the BinOptics Acquisition, BinOptics had, on a preliminary basis, federal net operating loss (NOL) carryforwards of approximately $44.0 million, which expire at various dates through 2034, and federal research and development tax credit carryforwards of $1.5 million. Although both the NOL and tax credit carryforwards are subject to change-in-control limitations within the Internal Revenue Code, we currently believe the limitation will not cause any of the carryforwards to expire unutilized. The aggregate net deferred income tax liability acquired in the BinOptics Acquisition is estimated to be $34.5 million arising from the BinOptics Acquisition, which includes a net deferred income tax asset of $16.9 million relating to NOL and tax credit carryforwards, and a net deferred income tax liability of $51.4 million related to the difference between the book and tax bases of the intangible and other assets acquired in the acquisition.
