(Viasystems), for total consideration of $248,824 in cash and 15,082 shares of TTM common stock with a fair value of $149,006, and thereby acquired all of the outstanding shares of capital stock and other equity rights of Viasystems. Additionally, in connection with the completion of the acquisition, the Company assumed and refinanced Viasystems’ debt, which was approximately $669,024 as of May 31, 2015. Viasystems was a worldwide provider of complex multi-layer rigid, flexible, and rigid-flex PCBs and custom electronic assemblies.

The purchase price of the Viasystems acquisition was allocated to tangible and intangible assets acquired, liabilities assumed and noncontrolling interest based on the fair value at the date of the acquisition (May 31, 2015). The excess of the purchase price over the fair value of net assets acquired and noncontrolling interest was allocated to goodwill. The fair value assigned to intangible assets acquired was based on estimates and assumptions made by management at the time of acquisition. The Company finalized the allocation of the purchase price during the second quarter of 2016. The fair values assigned are based on reasonable methods applicable to the nature of the assets acquired, liabilities assumed and noncontrolling interest. The following summarizes the final estimated fair values of net assets acquired and noncontrolling interest: (In thousands) Cash $ 79,662 Restricted cash 3,510 Accounts and notes receivables ($216,259 contractual gross receivables) 209,196 Inventories 132,216 Prepaid expenses and other current assets 30,633 Property, plant and equipment 427,457 Identifiable intangible assets 150,500 Goodwill 360,494 Deposits and other noncurrent assets 1,157 Current liabilities (256,705 ) Long-term debt (669,024 ) Other liabilities (63,966 ) Noncontrolling interest (7,300 ) Total $ 397,830 Goodwill represents the excess of the Viasystems purchase price over the fair value of tangibles and identifiable intangible assets acquired, liabilities assumed and noncontrolling interest. During the first two quarters of 2016, goodwill was adjusted to reflect: • an increase in current liabilities by $3,442 due to a reassessment of product claims and other contingent liabilities, and • an increase in other noncurrent liabilities by $22,182 primarily related to certain foreign tax liabilities. The goodwill acquired in the acquisition is not deductible for income tax purposes.

The U.S. ABL consists of three tranches comprised of a revolving credit facility of up to $150,000, a letter of credit facility of up to $75,000, and swingline loans of up to $30,000, provided that at no time may amounts outstanding under the tranches exceed in aggregate $150,000 or the applicable borrowing base, which is a percentage of the principal amount of Eligible Accounts, as defined in the U.S. ABL agreement. Borrowings under the U.S. ABL bear interest at either a floating rate of LIBOR plus a margin of 175 basis points or JP Morgan Chase Bank’s prime rate plus a margin of 75 basis points, at the Company’s option. At September 26, 2016, the weighted average interest rate on the outstanding borrowings under the U.S. ABL was 2.27%. The applicable margin can vary based on the remaining availability of the facility, from 150 to 200 basis points for LIBOR-based loans or from 50 to 100 basis points for JP Morgan Chase Bank’s prime rate-based loans. Other than availability and an event of default, there are no other provisions for the interest margin to increase. The U.S. ABL will mature on May 31, 2020. Loans made under the U.S. ABL are secured first by all of the Company’s domestic cash, receivables and inventories as well as by a second position against a significant amount of the assets of the Company and its domestic subsidiaries and a pledge of 65% of voting stock of the Company’s first tier foreign subsidiaries and are structurally senior to the Company’s convertible senior notes. See Convertible Senior Notes below. At September 26, 2016, $80,000 of the U.S. ABL was outstanding and classified as short-term debt. The Company and its domestic subsidiaries have fully and unconditionally guaranteed the full and timely payment of all Term Loan and U.S. ABL related obligations. The Asia ABL consists of two tranches comprised of a revolving credit facility of up to $150,000 and a letter of credit facility of up to $100,000, provided that at no time may amounts outstanding under both tranches exceed in aggregate $150,000 or the applicable borrowing base, which is a percentage of the principal amount of Eligible Accounts, as defined in the Asia ABL agreement. Borrowings under the Asia ABL bear interest at a floating rate of LIBOR plus 175 basis points. There is no provision, other than an event of default, for the interest margin to increase. The Asia ABL will mature on May 22, 2020. Loans made under the Asia ABL are secured by a portion of cash and receivables of certain of the Companies subsidiaries in Asia and are structurally senior to the Company’s domestic obligations, including the convertible senior notes. See Convertible Senior Notes below. Additionally, certain of the Company’s subsidiaries in Asia have fully and unconditionally guaranteed the full and timely payment of all Asia ABL related obligations. At September 26, 2016, none of the Asia ABL was outstanding. The Company is required to make scheduled payments of the outstanding Term Loan balance on a quarterly basis. Based on certain parameters defined in the Term Loan agreement, the Company may be required to make an additional principal payment on an annual basis. Any additional annual payments or prepayments reduce future required quarterly scheduled payments. During the three quarters ended September 26, 2016, the Company made debt principal payments totaling $106,482, representing normally scheduled principal payments as well as additional prepayments of principal. Any other outstanding balances under the Term Loan are due at the maturity date of May 31, 2021. Borrowings under the Term Loan are subject to various financial and operating covenants including maintaining a maximum total leverage ratio. Under the occurrence of certain events, the U.S. ABL and the Asia ABL are subject to various financial and operational covenants, including maintaining minimum fixed charge coverage ratios. At September 26, 2016, the Company was in compliance with the covenants under the Term Loan, the U.S. ABL and the Asia ABL. As of September 26, 2016 and December 28, 2015, remaining unamortized debt discount of $25,405 and $30,242, respectively, and debt issuance costs of $22,361 and $26,619, respectively, related to the Term Loan. These debt discount and debt issuance costs are recorded as a reduction of the Term Loan and are amortized over the duration of the Term Loan into interest expense using an effective interest rate of 7.50%. Additionally, remaining unamortized debt issuance costs related to the ABL Revolving Loans were $3,573 and $4,303 as of September 26, 2016 and December 28, 2015, respectively. These debt issuance costs are included in other non-current assets and are amortized to interest expense over the duration of the ABL Revolving Loans using the straight line method of amortization. At September 26, 2016, the remaining amortization period for the unamortized debt discount and debt issuance costs for both the Term Loan and the ABL Revolving Loans was 4.6 years. The Company is required to pay a commitment fee of 0.25% to 0.375% per annum on any unused portion of the U.S. ABL or Asia ABL based on utilization levels. Additionally, the Company also paid commitment fees of 0.5% per annum on the unused portion of the $90,000 senior secured revolving loan associated with the terminated 2012 credit agreement for the three quarters ended September 28, 2015. The Company incurred total commitment fees related to unused borrowing availability of $171 and $200 for the quarters ended September 26, 2016 and September 28, 2015, respectively, and $516 and $565 for the three quarters ended September 26, 2016 and September 28, 2015, respectively. As of September 26, 2016, the outstanding amount of the Term Loan was $841,143, of which $66,143 is included as short-term debt and the remaining $775,000 is included as long-term debt. Additionally, $80,000 of the U.S. ABL and none of the Asia ABL was outstanding as of September 26, 2016. Available borrowing capacity under the U.S. ABL and Asia ABL was $63,003 and $142,904, which includes letters of credit outstanding of $6,997 and $7,096 mentioned below, respectively, at September 26, 2016. Subsequent to September 26, 2016, the Company issued a new $775,000 Term Loan (New Term Loan) at an interest rate of LIBOR plus 4.25%, a reduction of 75 basis points from its previous Term Loan, and repaid in full the $841,143 of the previously issued Term Loan outstanding, which resulted in an overall net reduction of $66,143 in the Term Loan outstanding. Principal payments under the New Term Loan are due quarterly beginning in April 2020 with the balance due on May 31, 2021, the same maturity as the previous Term Loan. In addition, the Company amended its U.S. ABL credit facility to increase the amount available under the U.S. ABL to $200,000, reduce the applicable margin by 0.25% for both Eurodollar loans and ABR loans, and reduce the Letters of Credit Facilities to $50,000. Letters of Credit The Company has up to $75,000 and $100,000 Letters of Credit Facilities under the U.S. ABL and the Asia ABL, respectively, as mentioned above. As of September 26, 2016, letters of credit in the amount of $6,997 were outstanding under the U.S. ABL and $7,096 were outstanding under the Asia ABL with various expiration dates through September 2017. At December 28, 2015, certain letters of credit were securitized by cash collateral. As such the Company had recorded such cash as restricted cash on the consolidated condensed balance sheet as of December 28, 2015. As of September 26, 2016, none of the letters of credit were securitized by cash collateral. Convertible Senior Notes due 2020 The Company issued 1.75% convertible senior notes due December 15, 2020 in a public offering for an aggregate principal amount of $250,000 in 2013. The convertible senior notes bear interest at a rate of 1.75% per annum. Interest is payable semiannually in arrears on June 15 and December 15 of each year. The convertible senior notes are senior unsecured obligations and rank equally to the Company’s future unsecured senior indebtedness and are senior in right of payment to any of the Company’s future subordinated indebtedness. Convertible Senior Notes due 2015 The Company issued 3.25% convertible senior notes due on May 15, 2015 in a public offering for an aggregate principal amount of $175,000. In May 2015 the outstanding principal of $32,395 plus accrued interest was paid in full. As of September 26, 2016 and December 28, 2015, the following summarizes the equity components of the convertible senior notes included in additional paid-in capital: As of September 26, 2016 and December 28, 2015 Embedded Embedded Total (in thousands) Convertible senior notes due 2020 $ 60,227 $ (1,916 ) $ 58,311 The components of interest expense resulting from the convertible senior notes for the quarters and three quarters ended September 26, 2016 and September 28, 2015 are as follows: For the Quarter Ended For the Three quarters Ended September 26, September 28, September 26, September 28, (In thousands) Contractual coupon interest Convertible senior notes due 2020 $ 1,094 $ 1,094 $ 3,281 $ 3,281 Convertible senior notes due 2015 — — — 395 $ 1,094 $ 1,094 $ 3,281 $ 3,676 Amortization of debt discount Convertible senior notes due 2020 $ 2,025 $ 1,898 $ 5,977 $ 5,603 Convertible senior notes due 2015 — — — 554 $ 2,025 $ 1,898 $ 5,977 $ 6,157 Amortization of debt issuance costs Convertible senior notes due 2020 $ 203 $ 190 $ 599 $ 561 Convertible senior notes due 2015 — — — 56 $ 203 $ 190 $ 599 $ 617 As of September 26, 2016 and December 28, 2015, remaining unamortized debt discount of $39,449 and $45,426, respectively, and debt issuance costs of $3,953 and $4,552, respectively, related to the convertible senior notes. These debt discount and debt issuance costs are recorded as a reduction of the convertible senior notes and are being amortized to interest expense over the term of the convertible senior notes using the effective interest rate method. At September 26, 2016, the remaining weighted average amortization period for the unamortized senior convertible note discount and debt issuance costs was 4.2 years. For the quarter and three quarters ended September 26, 2016 and September 28, 2015, the amortization of the convertible senior notes due 2020 debt discount and debt issuance costs was based on an effective interest rate of 6.48%. For the three quarters ended September 28, 2015, the amortization of the convertible senior notes due 2015 debt discount and debt issuance costs was based on an effective interest rate of 8.37%. Other Credit Facility Additionally, the Company is party to a revolving loan credit facility (Chinese Revolver) with a lender in China. Under this arrangement, the lender has made available to the Company approximately $34,500 in unsecured borrowing with all terms of the borrowing to be negotiated at the time the Chinese Revolver is drawn upon. There are no commitment fees on the unused portion of the Chinese Revolver, and this arrangement expires in December 2016. As of September 26, 2016, the Chinese Revolver had not been drawn upon. Loss on Extinguishment of Debt The Company became a party to its current Term Loan and ABL Revolving Loans during the second quarter of 2015 in order to refinance and pay in full the remaining outstanding amount of $225,700 under an existing 2012 credit agreement, as well as to finance the acquisition of Viasystems and refinance Viasystems’ outstanding debt. As a result, the Company recognized losses of approximately $802 for the three quarters ended September 28, 2015 resulting from the write off of the remaining unamortized debt issuance costs associated with the terminated 2012 credit agreement.

Income Taxes

Income Taxes	9 Months Ended

Income Taxes	(8) Income Taxes The Company’s effective tax rate will generally differ from the U.S. federal statutory rate of 35% due to favorable tax rates associated with earnings from the Company’s operations in lower-tax jurisdictions such as China, the apportioned state income tax rates, generation of other credits and deductions available to the Company, changes in valuation allowances, and certain non-deductible items. During the quarter and three quarters ended September 26, 2016, the Company’s effective tax rate was impacted by a net discrete benefit of $240 and $6,733, respectively, related to (i) tax holiday benefits, (ii) release of uncertain tax positions due to expiration of the statute of limitations in a foreign jurisdiction, and (iii) accrued interest on existing uncertain tax positions. Additionally, no tax benefit was recorded on the losses incurred in the U.S. and certain foreign jurisdictions as a result of corresponding increases in the valuation allowances in these jurisdictions. The Company’s foreign earnings attributable to certain foreign subsidiaries will be indefinitely reinvested in such foreign jurisdictions and, therefore, no deferred tax liabilities for U.S. income taxes on undistributed earnings of those certain foreign subsidiaries are recorded. Certain entities in China operated under tax incentives effective through 2016. For the quarter and three quarters ended September 26, 2016, the tax incentives decreased Chinese taxes by approximately $1,564 and $6,089, respectively, which increased basic earnings per share by $0.02 and $0.06, and increased diluted earnings per share by $0.01 and $0.05, respectively.

Significant Customers and Concentration of Credit Risk	(10) Significant Customers and Concentration of Credit Risk In the normal course of business, the Company extends credit to its customers, which are concentrated primarily in the automotive, cellular phone, computer, networking and communications and aerospace and defense industries. Most customers to which the Company extends credit are located outside the United States, with the exception of certain customers in the aerospace and defense industries. The Company performs ongoing credit evaluations of customers, does not require collateral, and considers the credit risk profile of the entity from which the receivable is due in further evaluating collection risk. The Company’s customers include both OEM and EMS companies. The Company’s OEM customers often direct a significant portion of their purchases through EMS companies. While the Company’s customers include both OEM and EMS providers, the Company measures customer concentration based on OEM companies, as they are the ultimate end customers. For both of the quarters ended September 26, 2016 and September 28, 2015, one customer accounted for approximately 17% of the Company’s net sales. For the three quarters ended September 26, 2016 and September 28, 2015, one customer accounted for approximately 13% and 21%, respectively, of the Company’s net sales. There were no other customers that accounted for 10% or more of net sales for the quarters or three quarters ended September 26, 2016 and September 28, 2015.

Fair Value Measures

Fair Value Measures	9 Months Ended
	Sep. 26, 2016
Fair Value Measures	(11) Fair Value Measures The Company measures at fair value its financial and non-financial assets by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The carrying amount and estimated fair value of the Company’s financial instruments at September 26, 2016 and December 28, 2015 were as follows: September 26, 2016 December 28, 2015 Carrying Fair Carrying Fair (In thousands) Term and revolving loans $ 873,377 $ 921,143 $ 970,764 $ 935,000 Convertible senior notes due 2020 206,598 325,625 200,022 230,950 Capital lease 1,875 1,875 — — The fair value of the long-term debt was estimated based on quoted market prices or discounting the debt over its life using current market rates for similar debt as of September 26, 2016 and December 28, 2015, which are considered Level 1 and Level 2 inputs. The fair value of the convertible senior notes was estimated based on quoted market prices of the securities on an active exchange, which are considered Level 1 and Level 2 inputs. As of September 26, 2016 and December 28, 2015, the Company’s other financial instruments also included cash and cash equivalents, accounts receivable and accounts payable. Due to short-term maturities, the carrying amount of these instruments approximates fair value. Our cash and cash equivalents at September 26, 2016 consisted of $117,566 held in the U.S., with the remaining $174,217 held by foreign subsidiaries. The majority of the Company’s non-financial assets and liabilities, which include goodwill, intangible assets, inventories, and property, plant and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur such that a non-financial instrument is required to be evaluated for impairment (at least annually for goodwill), based upon a comparison of the non-financial instrument’s fair value to its carrying value, an impairment is recorded to reduce the carrying value to the fair value, if the carrying value exceeds the fair value. The Company recognized impairment charges related to long-lived assets of $3,346 in the three quarters ended September 26, 2016. The fair values of the impaired long-lived assets were based on level 2 and 3 inputs. There was no impairment of long-lived assets recognized in the quarter ended September 26, 2016 or for the quarter and three quarters ended September 28, 2015.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies	(12) Commitments and Contingencies Legal Matters The Company is subject to various legal matters, which it considers normal for its business activities. While the Company currently believes that the amount of any reasonably possible loss for known matters would not be material to the Company’s financial condition, the outcome of these actions is inherently difficult to predict. In the event of an adverse outcome, the ultimate potential loss could have a material adverse effect on the Company’s financial condition or results of operations in a particular period. The Company has accrued amounts for its loss contingencies which are probable and estimable as of September 26, 2016 and December 28, 2015. However, these amounts are not material to the consolidated condensed financial statements of the Company. Environmental Matters The process to manufacture PCBs requires adherence to city, county, state, federal, and foreign environmental regulations regarding the storage, use, handling, and disposal of chemicals, solid wastes, and other hazardous materials, as well as compliance with air quality standards and chemical use reporting. The Company believes that its facilities in the United States, Canada and Mexico comply in all material respects with applicable environmental laws and regulations. In China, governmental authorities have adopted new rules and regulations governing environmental issues. An update to the Chinese environmental waste water law was issued in late 2012, allowing for an interim period in which plants subject to such law may install equipment that meets the new regulatory regime. Some of the Company’s plants in China are not yet in full compliance with the updated environmental regulations. The Company believes it has developed plans acceptable to the Chinese government and is in the process of implementing these plans. The Company does not anticipate any immediate risk of government fines or temporary closure of its Chinese plants. The Company has established and enacted an investment plan related to the efforts to come into full compliance with the new regulations. The 2016 capital expenditure costs expected for these plans are included in the Company’s capital expenditure projections.

For the three quarters ended September 26, 2016, the effect of shares of common stock related to the Company’s convertible senior notes, based on the if-converted method, were not included in the computation of dilutive earnings per share as the impact would be anti-dilutive. For the quarter and three quarters ended September 28, 2015, potential shares of common stock, consisting of stock options to purchase approximately 422 shares of common stock at exercise prices ranging from $5.78 to $16.82 per share, 2,326 RSUs, and 275 PRUs were not included in the computation of diluted earnings per share because the Company incurred a net loss and, as a result, the impact would be anti-dilutive. For the quarters and three quarters ended September 26, 2016 and September 28, 2015, outstanding warrants to purchase 25,940 and 27,500 shares of common stock, respectively, were not included in the computation of dilutive earnings per share because the strike price of the warrants to purchase the Company’s common stock were greater than the average market price of common shares during the applicable quarters and three quarters, and therefore, the effect would be anti-dilutive.

Stock-Based Compensation	(14) Stock-Based Compensation Stock-based compensation expense is recognized in the accompanying consolidated condensed statements of operations as follows: Quarter Ended Three quarters Ended September 26, September 28, September 26, September 28, (In thousands) Cost of goods sold $ 412 $ 322 $ 1,161 $ 790 Selling and marketing 268 294 749 834 General and administrative 2,119 2,056 5,980 5,402 Stock-based compensation expense recognized $ 2,799 $ 2,672 $ 7,890 $ 7,026 Performance-based Restricted Stock Units The Company maintains a long-term incentive program for executives that provides for the issuance of PRUs, representing hypothetical shares of the Company’s common stock that may be issued. Under the PRU program, a target number of PRUs is awarded at the beginning of each three-year performance period. The number of shares of common stock released at the end of the performance period will range from zero to 2.4 times the target number depending on performance during the period. The performance metrics of the PRU program are based on (a) annual financial targets, which are based on revenue and EBITDA (earnings before interest, tax, depreciation, and amortization expense), each equally weighted, and (b) an overall modifier based on the Company’s total stockholder return (TSR) relative to a group of peer companies selected by the Company’s compensation committee, over the three-year performance period. The Company records stock-based compensation expense for PRU awards granted based on management’s periodic assessment of the probability of the PRU awards vesting. For the quarters and three quarters ended September 26, 2016, management determined that vesting of the PRU awards was probable. PRUs activity for the three quarters ended September 26, 2016 was as follows: Shares Weighted (In thousands) Outstanding target shares at December 28, 2015 301 $ 8.58 Granted 347 6.46 Change in units due to annual financial target performance achievement (20 ) 6.46 Outstanding target shares at September 26, 2016 628 $ 7.48 Restricted Stock Units The Company granted 1,814 and 1,301 restricted stock units during the three quarters ended September 26, 2016 and September 28, 2015, respectively. The RSUs granted have a weighted-average fair value per unit of $6.74 and $9.15 for the three quarters ended September 26, 2016 and September 28, 2015, respectively. The fair value for RSUs granted is based on the closing share price of the Company’s common stock on the date of grant. There were no restricted stock units granted during the quarters ended September 26, 2016 and September 28, 2015. Stock Options The Company did not grant any stock option awards during the quarters and three quarters ended September 26, 2016 and September 28, 2015.

Segment Information

Segment Information	9 Months Ended

Segment Information	(15) Segment Information The operating segments reported below are the Company’s segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company has reviewed its reportable operating segments and determined that it continues to have two reportable operating segments: PCB and E-M Solutions. This determination was made based on the criteria of earning revenues and incurring expenses, the Company’s organizational structure which has segment managers who report to the chief operating decision maker, discrete financial information, and the aggregation of similar operating segments into reportable operating segments. Factors considered to determine whether operating segments can be aggregated into reportable segments included similarity regarding economic characteristics, products, production processes, type or classes of customers, distribution methods, and regulatory environments. The Company, including the chief operating decision maker, evaluates segment performance based on operating segment income, which is operating income before amortization of intangibles. Interest expense and interest income are not presented by segment since they are not included in the measure of segment profitability reviewed by the chief operating decision maker.
