Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Jan. 02, 2017
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Such estimates include the sales return reserve; accounts receivable; inventories; goodwill; intangible assets and other long-lived assets; self insurance reserves; product warranty liabilities; environmental liabilities; legal contingencies; income taxes; and others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. The actual results we experienced may differ materially and adversely from our estimates. To the extent there are material differences between the estimates and actual results, our future result of operations will be affected. Principles of Consolidation The consolidated financial statements include the accounts of TTM Technologies, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Foreign Currency Translation and Transactions The functional currency of certain of the Company’s subsidiaries is either the Chinese Renminbi (RMB) or the Hong Kong Dollar. Accordingly, assets and liabilities are translated into U.S. dollars using period-end Cash Equivalents The Company considers highly liquid investments with insignificant interest rate risk and original maturities to the Company of three months or less to be cash equivalents. Cash equivalents consist primarily of interest-bearing bank accounts and money market funds. The Company considers highly liquid investments with an effective maturity to the Company of more than three months and less than one year to be short-term investments. As of December 28, 2015, the Company had $3,530 of restricted cash related to the collaterization of certain letter of credit arrangements. As of January 2, 2017, all such letter of credit arrangements requiring collaterization had expired. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are reflected at estimated net realizable value, do not bear interest and do not generally require collateral. The Company performs credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness. The Company maintains an allowance for doubtful accounts based upon a variety of factors. The Company reviews all open accounts and provides specific reserves for customer collection issues when it believes the loss is probable, considering such factors as the length of time receivables are past due, the financial condition of the customer, and historical experience. The Company also records a reserve for all customers, excluding those that have been specifically reserved for, based upon evaluation of historical losses. The following summarizes the activity in the Company’s allowance for doubtful accounts for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Balance at beginning of year $ 1,525 $ 696 $ 518 Additions charged to expense 1,560 854 214 Deductions (223 ) (26 ) (34 ) Effect of foreign currency exchange rates (11 ) 1 (2 ) Balance at end of year $ 2,851 $ 1,525 $ 696 Inventories Inventories are stated at the lower of cost (determined on a first-in, first-out Property, Plant and Equipment, Net Property, plant and equipment are recorded at cost. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Assets recorded under leasehold improvements are amortized using the straight-line method over the lesser of their useful lives or the related lease term. The Company uses the following estimated useful lives: Land use rights 50-99 years Buildings and improvements 7-50 years Machinery and equipment 3-12 years Furniture and fixtures 3-7 years Upon retirement or other disposition of property, plant and equipment, the cost and related accumulated depreciation are removed from the accounts. The resulting gain or loss is included in the determination of operating income in the period incurred. Depreciation and amortization expense on property, plant and equipment was $156,229, $133,508, and $95,349 for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively. The Company capitalizes interest on borrowings during the active construction period of major capital projects. Capitalized interest is amortized over the average useful lives of such assets, which primarily consist of buildings and machinery and equipment. The Company capitalized interest costs of $1,876, $888, and $551 during the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively, in connection with various capital projects. Major renewals and betterments are capitalized and depreciated over their estimated useful lives while minor expenditures for maintenance and repairs are included in operating income as incurred. Goodwill Goodwill represents the excess of purchase price of an acquisition over the fair value of net assets acquired. Goodwill is not amortized but instead is assessed for impairment, at a reporting unit level, annually and when events and circumstances warrant an evaluation. In making this assessment, management relies on a number of factors, including expected future operating results, business plans, economic projections, anticipated future cash flows, business trends and market conditions. The Company has two reportable operating segments consisting of four reporting units. The Company evaluates its goodwill on an annual basis in the fourth quarter or more frequently if it believes indicators of impairment exist. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting units is less than its carrying amount, it conducts a two-step Intangible Assets Intangible assets include customer relationships, technology and trade names, which are being amortized over their estimated useful lives using straight-line and accelerated methods. The estimated useful lives of such intangibles range from 3 years to 10 years. Impairment of Long-lived Assets Long-lived tangible assets, including property, plant and equipment, assets held for sale, and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset or asset groups may not be recoverable. The Company regularly evaluates whether events or circumstances have occurred that indicate possible impairment and relies on a number of factors, including expected future operating results, business plans, economic projections, and anticipated future cash flows. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life in measuring whether the assets are recoverable. Measurement of the amount of impairment, if any, is based upon the difference between the asset’s carrying value and estimated fair value. Fair value is determined through various valuation techniques, including cost-based, market and income approaches as considered necessary. See Note 4 for information regarding the impairment of long-lived assets during the years 2016 and 2014. The Company classifies assets to be sold as assets held for sale when (i) Company management has approved and commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition and is ready for sale; (iii) an active program to locate a buyer and other actions required to sell the asset have been initiated; (iv) the sale of the asset is probable; (v) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Assets classified as held for sale are recorded at the lower of the carrying amount or fair value less the cost to sell and are a component of prepaid expenses and other current assets in the consolidated balance sheet. The Company classifies assets held for use when a decision to dispose of an asset or a business is made and the held for sale criteria are not met. Assets of the business are evaluated for recoverability in the following order: (i) assets other than goodwill, property and intangibles; (ii) property and intangibles subject to amortization; and (iii) goodwill. In evaluating the recoverability of property and intangible assets subject to amortization, in a held for use business, the carrying value is first compared to the sum of the undiscounted cash flows expected to result from the use and eventual disposition. If the carrying value exceeds the undiscounted expected cash flows, then a fair value analysis is performed. An impairment charge is recognized if the carrying value exceeds the fair value. Revenue Recognition The Company derives its revenue primarily from the sale of PCBs using customer supplied engineering and design plans and recognizes revenue when: (i) persuasive evidence of a sales arrangement exists; (ii) the sales terms are fixed or determinable; (iii) title and risk of loss have transferred; and (iv) collectability is reasonably assured — generally when products are shipped to the customer, except in situations in which title passes upon receipt of the products by the customer. In this case, revenues are recognized upon notification that customer receipt has occurred. The Company does not have customer acceptance provisions, but it does provide its customers a limited right of return for defective PCBs. The Company accrues an estimated amount for sales returns and allowances related to defective PCBs at the time of sale based on its ability to estimate sales returns and allowances using current and historical information. The reserve for sales returns and allowances is included as a reduction to revenue and accounts receivable, net. Shipping and handling fees and related freight costs and supplies associated with shipping products to customers are included as a component of cost of goods sold. Incremental warranty costs that are not related to sales returns are recorded in accrued expenses and cost of goods sold. The following summarizes the activity in the Company’s allowance for sales returns and allowances for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Balance at beginning of year $ 7,789 $ 6,890 $ 6,028 Additions charged to expense 22,060 21,728 38,440 Deductions (21,728 ) (20,832 ) (37,578 ) Effect of foreign currency exchange rates (2 ) 3 — Balance at end of year $ 8,119 $ 7,789 $ 6,890 Stock-Based Compensation The Company recognizes stock-based compensation expense in its consolidated financial statements for its incentive compensation plan awards. The incentive compensation plan awards include performance-based restricted stock units, restricted stock units, and stock options and the associated compensation expense is based on the grant date fair value of the awards, net of estimated forfeitures, as well as an assessment of probability of the performance-based awards vesting. Compensation expense for the incentive compensation plan awards is recognized on a straight line basis over the vesting period of the awards. The fair value of performance-based restricted stock units is estimated on the grant date using a Monte Carlo simulation model based on the underlying common stock closing price as of the date of grant, the expected term, stock price volatility, and risk-free interest rates. The fair value of restricted stock units is measured on the grant date based on the quoted closing market price of the Company’s common stock. The fair value of the stock options is estimated on the grant date using the Black-Scholes option pricing model based on the underlying common stock closing price as of the date of grant, the expected term, stock price volatility, and risk-free interest rates. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets or liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be settled or realized. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax assets are reviewed for recoverability, and the Company records a valuation allowance to reduce its deferred income tax assets when it is more likely than not that all or some portion of the deferred income tax assets will not be realized. The Company has various foreign subsidiaries formed or acquired to conduct or support its business outside the United States. The Company does not provide for U.S. income taxes on undistributed earnings for certain foreign subsidiaries as management expects the foreign earnings will be indefinitely reinvested in such foreign jurisdictions. For certain subsidiaries within China, indefinite investment of undistributed earnings has not been asserted between the respective subsidiaries and their foreign parent entity and therefore, a deferred tax liability for the foreign tax impacts has been recorded on the undistributed earnings of these subsidiaries. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Estimated interest and penalties related to underpayment of income taxes are recorded as a component of income tax provision in the consolidated statement of operations. Self Insurance The Company is primarily self insured in North America for group health insurance and workers compensation benefits provided to U.S. employees. The Company also purchases stop loss insurance to protect against annual claims per individual and at an aggregate level. The individual insured stop loss on the Company’s self insurance is $350 per individual for group health insurance and $250 per individual for worker’s compensation benefits. Self insurance liabilities are estimated for claims incurred but not paid based on judgment, using the Company’s historical claim data and information and analysis provided by actuarial and claim advisors, the Company’s insurance carrier and brokers. The Company has accrued $5,375 and $5,182 for self insurance liabilities as of January 2, 2017 and December 28, 2015, respectively, and these amounts are reflected within accrued salaries, wages and benefits in the consolidated balance sheets. Group health insurance and workers compensation benefits for the Company’s plants in China are fully insured with third parties. Convertible Debt The accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion require the debt and equity components to be separately accounted for in a manner that reflects the Company’s nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to the Company’s at the time of issuance. The difference between the debt recorded at inception and its principal amount is to be accreted to principal through interest expense through the estimated life of the note. Value Added and Sales Tax Collected from Customers As a part of the Company’s normal course of business, value added and sales taxes are collected from customers. Such taxes collected are remitted, in a timely manner, to the appropriate governmental tax authority on behalf of the customer. The Company’s policy is to present revenue and costs, net of value added and sales taxes. Fair Value Measures The Company measures at fair value certain of its financial and non-financial Level 1 — Quoted market prices in active markets for identical assets or liabilities; Level 2 — Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable, such as interest rate and yield curves, and market-corroborated inputs); and Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting unit to develop its own assumptions. Environmental Accrual Accruals for estimated costs for environmental obligations generally are recognized no later than the date when the Company identifies what cleanup measures, if any, are likely to be required to address the environmental condition. Included in such obligations are the estimated direct costs to investigate and address the conditions, and the associated engineering, legal and consulting costs. In making these estimates, the Company considers information that is currently available, existing technology, enacted laws and regulations, and its estimates of the timing of the required remedial actions. Such accruals are initially measured on a discounted basis — and are adjusted as further information becomes available or circumstances change — and are accreted to the payable amount over time. Earnings Per Share Basic earnings per common share excludes dilution and is computed by dividing net income attributable to TTM Technologies, Inc. stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflect the potential dilution that could occur if stock options, convertible senior notes or other common stock equivalents were exercised or converted into common stock. The dilutive effect of stock options or other common stock equivalents is calculated using the treasury stock method, while the dilutive effect of convertible senior notes is calculated using the if-converted Comprehensive Income Comprehensive income includes changes to equity accounts that were not the result of transactions with stockholders. Comprehensive income is comprised of net income (loss), changes in the cumulative foreign currency translation adjustments and realized and unrealized gains or losses on hedged derivative instruments and available for sale securities. Noncontrolling Interest Holdings As of January 2, 2017, noncontrolling interest consists of a 5% equity interest in a manufacturing facility in Huiyang, China which was acquired along with other assets and liabilities of Viasystems. Loss Contingencies The Company establishes an accrual for an estimated loss contingency when it is both probable that an asset has been impaired or that a liability has been incurred and the amount of the loss can be reasonably estimated. Any legal fees expected to be incurred in connection with a contingency are expensed as incurred.

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.

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 liabilities associated with certain tax positions at certain foreign jurisdictions. The goodwill acquired in the acquisition is not deductible for income tax purposes.

At January 2, 2017, the weighted average interest rate on the outstanding borrowings under the Term Loan was 5.25%. There is no provision, other than an event of default, for the interest margin to increase. The Term Loan B will mature on May 31, 2021. The Term Loan B is secured by a significant amount of the assets of the Company and a pledge of 65% of voting stock of the Company’s first tier foreign subsidiaries and is structurally senior to the Company’s convertible senior notes. See Convertible Senior Notes below. The amended U.S. ABL consists of three tranches comprised of a revolving credit facility of up to $200,000, a letter of credit facility of up to $50,000, and swingline loans of up to $30,000, provided that at no time may amounts outstanding under the tranches exceed in aggregate $200,000 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 150 basis points or JP Morgan Chase Bank’s prime rate plus a margin of 50 basis points, at the Company’s option. At January 2, 2017, 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 125 to 175 basis points for LIBOR-based loans and from 25 to 75 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 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 January 2, 2017, $80,000 of the U.S. ABL was outstanding. The Company and its domestic subsidiaries have fully and unconditionally guaranteed the full and timely payment of all Term Loan B 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 140 basis points. At January 2, 2017, the weighted average interest rate on the outstanding borrowings under the Asia ABL was 2.17%. 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 the Company’s Asia Pacific cash and receivables and are structurally senior to the Company’s domestic obligations, including the convertible senior notes. See Convertible Senior Notes below. The Company’s Asia Pacific subsidiary and certain of its subsidiaries have fully and unconditionally guaranteed the full and timely payment of all Asia ABL related obligations. At January 2, 2017, $30,000 of the Asia ABL was outstanding. During the year ended January 2, 2017, the Company made net debt principal payments totaling $217,625 representing normal principal payments as well as additional prepayments of principal. The Company is not required to make quarterly scheduled payments of the outstanding Term Loan B balance due to mandatory payments and optional loan prepayments applied to date. Based on certain parameters defined in the Term Loan B agreement, including a secured leverage ratio, the Company may be required to make an additional principal payment on an annual basis. Any remaining outstanding balances under the Term Loan B are due at the maturity date of May 31, 2021. Borrowings under the Term Loan B are subject to 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 financial and operational covenants, including maintaining minimum fixed charge coverage ratios.

There was no unamortized debt discount for the Term Loan B at January 2, 2017. These debt discount and debt issuance costs are recorded as a reduction of the Term Loan B and the Term Loan at January 2, 2017 and December 28, 2015, respectively, and are amortized over the duration of the Term Loan B and Term Loan into interest expense using an effective interest rate of 5.29% and 7.50%, respectively. Additionally, remaining unamortized debt issuance costs related to the ABL Revolving Loans were $3,423 and $4,303 as of January 2, 2017 and December 28, 2015, respectively.

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 balance sheet as of December 28, 2015. As of January 2, 2017, none of the letters of credit were securitized by cash collateral. Convertible Senior Notes 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 2014. 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. Conversion: On or after March 15, 2020 until the close of business on the third scheduled trading day preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon conversion, for each $1 principal amount of notes, the Company will pay shares of our common stock, cash or a combination of cash and shares of our common stock at its election, if applicable, based on a daily conversion value calculated on a proportionate basis for each day of the 80 trading day observation period. All conversions occurring on the same date or on or after March 15, 2020 shall be settled using the same settlement method. Additionally, in the event of a fundamental change as defined in the indenture governing the notes, or other conversion rate adjustments such as share splits or combinations, other distributions of shares, cash or other assets to stockholders, including self-tender transactions (Other Conversion Rate Adjustments), the conversion rate may be modified to adjust the number of shares per $1 principal amount of the notes. As of January 2, 2017, none of the criteria for a fundamental change or a conversion rate adjustment had been met. The maximum number of shares issuable upon conversion, including the effect of a fundamental change and subject to Other Conversion Rate Adjustments, would be 32,425. Note Repurchase: Convertible Note Hedge and Warrant Transaction: 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 January 2, 2017 and December 28, 2015, the following summarizes the equity components of the convertible senior notes included in additional paid-in As of January 2, 2017 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 years ended January 2, 2017, December 28, 2015 and December 29, 2014 were as follows: For the Year Ended January 2, December 28, December 29, (In thousands) Contractual coupon interest Convertible Senior Notes due 2020 $ 4,375 $ 4,375 $ 4,367 Convertible Senior Notes due 2015 — 395 1,053 $ 4,375 $ 4,770 $ 5,420 Amortization of debt discount Convertible Senior Notes due 2020 $ 8,034 $ 7,532 $ 7,102 Convertible Senior Notes due 2015 — 554 1,395 $ 8,034 $ 8,086 $ 8,497 Amortization of debt issuance costs Convertible Senior Notes due 2020 $ 805 $ 755 $ 712 Convertible Senior Notes due 2015 — 56 141 $ 805 $ 811 $ 853 As of January 2, 2017 and December 28, 2015, remaining unamortized debt discount of $37,392 and $45,426, respectively, and debt issuance costs of $3,747 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 January 2, 2017, the remaining weighted average amortization period for the unamortized senior convertible note discount and debt issuance costs was 4 years. For the years ended January 2, 2017, December 28, 2015 and December 29, 2014, 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 years ended December 28, 2015 and December 29, 2014, 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%. Loss on Extinguishment of Debt During the year ended January 2, 2017 and as mentioned previously, the Company repaid the remaining outstanding balances of its Term Loan. As a result, the Company recognized losses of $47,767 primarily associated with the write off of the remaining unamortized debt discount and debt issuance costs. During the year ended December 28, 2015, the Company paid in full the remaining outstanding amount of $225,700 under an existing 2012 credit agreement. As a result, the Company recognized losses of approximately $802 resulting from the write off of the remaining unamortized debt issuance costs associated with the terminated 2012 credit agreement. During the year ended December 29, 2014, the Company repurchased $6,541 of its convertible senior notes due 2015 at approximately 103.4% of their principal amounts. The repurchases were accounted for as extinguishments of debt and, accordingly, the Company recognized losses of approximately $506 primarily associated with the premium paid to repurchase the convertible senior notes and the recognition of related unamortized debt discount and issuance costs. 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 $30,200 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 January 2018. As of January 2, 2017, the Chinese Revolver had not been drawn upon.

Income Taxes	(9) Income Taxes The components of income (loss) before income taxes for the years ended January 2, 2017, December 28, 2015 and December 29, 2014 are: For the Year Ended January 2, December 28, December 29, (In thousands) United States $ (85,323 ) $ (104,068 ) $ (3,201 ) Foreign 152,325 113,044 25,492 Income before income taxes $ 67,002 $ 8,976 $ 22,291 The Company expects its foreign earnings attributable to all foreign subsidiaries will be indefinitely reinvested in such foreign jurisdictions and, therefore, no deferred tax liabilities for U.S. income taxes on undistributed earnings are recorded. The undistributed earnings of the foreign subsidiaries amounted to approximately $717,854 as of January 2, 2017. The determination of unrecognized deferred tax liability related to these undistributed earnings is not practicable. Foreign earnings attributable to certain manufacturing subsidiaries within China may be repatriated to the parent holding company located in Hong Kong, and therefore, a deferred tax liability of approximately $6,903 for the foreign tax impact has been recorded on the undistributed earnings of these subsidiaries. The components of income tax provision for the years ended January 2, 2017, December 28, 2015 and December 29, 2014 are: For the Year Ended January 2, December 28, December 29, (In thousands) Current (provision) benefit: Federal $ (342 ) $ 477 $ 1,717 State (512 ) (345 ) (216 ) Foreign (29,672 ) (19,379 ) (5,385 ) Total current (30,526 ) (19,247 ) (3,884 ) Deferred (provision) benefit: Federal 715 (10,084 ) (829 ) State — (2,184 ) 133 Foreign (1,616 ) (3,079 ) (3,018 ) Total deferred (901 ) (15,347 ) (3,714 ) Total provision $ (31,427 ) $ (34,594 ) $ (7,598 ) The following is a reconciliation of the provision for income taxes at the statutory federal income tax rate compared to the Company’s provision for income taxes for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Statutory federal income tax $ (22,780 ) $ (3,052 ) $ (7,579 ) State income taxes, net of federal benefit and state tax credits 906 (345 ) (84 ) Foreign deemed dividends (4,585 ) (5,691 ) — Acquisition related expenses (591 ) (7,692 ) — Intercompany profit in inventory elimination (335 ) 596 — Permanently reinvested earnings assertion — 8,281 — Foreign tax differential on foreign earnings 17,530 15,543 (6,243 ) Change in valuation allowance (19,119 ) (39,148 ) 5,321 Uncertain tax positions (3,464 ) (3,911 ) — Federal research and development credits 1,270 1,270 1,020 Loss on extinguishment of debt — — — Other (259 ) (445 ) (33 ) Total provision for income taxes $ (31,427 ) $ (34,594 ) $ (7,598 ) Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The significant components of the net deferred income tax assets as of January 2, 2017 and December 28, 2015 are as follows: As of January 2, December 28, (In thousands) Deferred income tax assets: Net operating loss carryforwards $ 212,553 $ 223,456 Reserves and accruals 32,420 36,137 Tax credit carryforwards 18,148 19,719 Stock-based compensation 4,965 4,609 Original issue discount on convertible senior notes 15,329 18,876 Property, plant and equipment 13,398 12,945 Other deferred income tax assets 2,036 3,172 298,849 318,914 Less: valuation allowance (221,951 ) (234,192 ) 76,898 84,722 Deferred income tax liabilities: Discount on convertible senior notes (13,410 ) (16,495 ) Repatriation of foreign earnings (6,903 ) (4,776 ) Property, plant and equipment basis differences (32,582 ) (34,716 ) Goodwill and intangible amortization (36,097 ) (41,790 ) Other deferred income tax assets (1,955 ) (93 ) Net deferred income tax liabilities $ (14,049 ) $ (13,148 ) Deferred income tax liabilities, net: Current deferred income taxes $ — $ — Noncurrent deferred income taxes (14,049 ) (13,148 ) As of January 2, 2017, the Company had the following net operating loss (“NOL”) carryforwards: $510,093 in the U.S. for federal, $561,708 in various U.S. states, $51,694 in China, $36,205 in Hong Kong and $164 in the Netherlands. The U.S. federal NOLs expire in 2019 through 2036, the various U.S. states’ NOLs expire in 2017 through 2036, the China NOLs expire in 2017 through 2021, the Hong Kong NOLs carryforward indefinitely, and the Netherlands NOLs expire in 2017. Further, the Company’s tax credits were approximately $26,451 of which $8,481 carryforward indefinitely. In connection with the Company’s acquisition of Viasystems, there was more than a 50% change in ownership under Section 382 of the Internal Revenue Code of 1986, as amended, and regulations issued there under. As a consequence, the utilization of the acquired Viasystems U.S. NOLs is limited to approximately $9,826 per year. In addition, the Company recognized certain gains built in at the time of the ownership change, which increase the limitation by approximately $47,463 for each of the first 5 years after the acquisition. Any unused limitation in a year can be carried over to succeeding years. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred income tax assets will not be realized. Based on historical performance and future expectations, the Company has a full valuation allowance on its net U.S. deferred tax assets. Certain subsidiaries within China continue to have NOL carryforwards in various tax jurisdictions that the Company has determined are not more likely than not to be utilized. As a result, a full valuation allowance has been recorded for these subsidiaries at January 2, 2017. For the remaining net deferred income tax asset, management has determined that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax asset. The following summarizes the activity in the Company’s valuation allowance for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Balance at beginning of year $ 234,192 $ 38,839 $ 44,160 (Reduction) additions related to acquisition (18,234 ) 177,699 — Additions charged to expense 5,993 39,149 6,458 Reduction related to sale of foreign subsidiary — (21,495 ) — Deductions — — (11,779 ) Balance at end of year $ 221,951 $ 234,192 $ 38,839 Certain entities within China operated under the high and new technology enterprise (HNTE) status enabling those entities to enjoy certain tax holidays, which were effective for the years ended January 2, 2017, December 28, 2015 and December 29, 2014. The tax holidays as well as enhanced research and development (R&D) deductions decreased Chinese taxes by $7,666, $7,600 and $1,877, which (decreased) increased both basic and dilutive (loss) earnings per share by $(0.08), $(0.08) and $0.02, for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively. HTNE status and the related tax holidays expire at various dates through 2017, but the Company expects to continue to file for renewal of such HNTE status for the foreseeable future. A reconciliation of the beginning and ending amount of unrecognized tax benefits, exclusive of accrued interest and penalties, is as follows: For the Year Ended January 2, December 28, December 29, (In thousands) Beginning balance $ 15,404 $ 2,441 $ 2,298 Additions related to acquisition 22,182 11,293 — Additions based on tax positions related to the current year 5,389 3,349 220 Additions for tax positions of prior years 1,545 14 286 Reductions for tax positions of prior years (2,286 ) (1,371 ) — Lapse of statute (2,507 ) (322 ) (363 ) Ending balance $ 39,727 $ 15,404 $ 2,441 As of January 2, 2017 and December 28, 2015, the Company recorded unrecognized tax benefits of $28,037 and $10,649, respectively, as well as interest and penalties of $10,754 and $12,202, respectively, to other long-term liabilities. The Company has also recorded unrecognized tax benefits of $11,689 and $4,755 against certain deferred tax assets as of January 2, 2017 and December 28, 2015, respectively. The amount of unrecognized tax benefits that would, if recognized, reduce the Company’s effective income tax rate in any future periods is $38,791 including interest and penalties. The Company expects its unrecognized tax benefits to decrease by $641 along with related interest of $987 over the next 12 months due to expiring statutes. As of January 2, 2017, the Company is subject to (i) U.S. federal income tax examination and / or NOL adjustment for tax years from 1999 to 2016, (ii) state and local income tax examination for tax years 1999 to 2016, and (iii) foreign income tax examinations generally for tax years from 2006 to 2016.

Significant Customers and Concentration of Credit Risk	(11) 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 OEMs 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 the years ended January 2, 2017, December 28, 2015 and December 29, 2014, one customer accounted for approximately 15%, 20% 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 years ended January 2, 2017, December 28, 2015 and December 29, 2014.

Fair Value Measures

Fair Value Measures	12 Months Ended

Fair Value Measures	(12) Fair Value Measures The Company measures at fair value its financial and non-financial The carrying amount and estimated fair value of the Company’s financial instruments as of January 2, 2017 and December 28, 2015 were as follows: As of January 2, 2017 December 28, 2015 Carrying Fair Value Carrying Fair Value (In thousands) Term and Revolving Loans $ 809,023 $ 818,750 $ 970,764 $ 935,000 Convertible Senior Notes due 2020 208,861 380,875 200,022 230,950 Capital lease 1,798 1,798 — — 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 January 2, 2017 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 January 2, 2017 and December 28, 2015, the Company’s other financial instruments also included cash and cash equivalents, accounts receivable, accounts payable and equipment payables. Due to short-term maturities, the carrying amount of these instruments approximates fair value. Our cash and cash equivalents at January 2, 2017 consisted of $50,227 held in the U.S., with the remaining $206,050 held by foreign subsidiaries. The majority of the Company’s non-financial non-financial non-financial For the years ended January 2, 2017 and December 29, 2014, the following assets were measured at fair value on a nonrecurring basis using the type of inputs shown: Fair Value Measurements Using: January 2, Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Losses for (In thousands) Long-lived assets held and use $ 2,254 $ — $ — $ 2,254 $ 1,953 Assets held for sale — — — — 1,393 $ 3,346 Fair Value Measurements Using: December 29, Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Losses for (In thousands) Assets held for sale $ 21,031 $ — $ 21,031 $ — $ 1,845 There was no impairment of long-lived assets recognized in the year ended December 28, 2015. The fair values of assets held for sale were primarily determined using appraisals and comparable prices of similar assets, which are considered to be Level 2 inputs. Additionally, the Company has capitalized software costs in accordance with U.S. GAAP. During the year ended January 2, 2017, the Company determined that certain capitalized costs no longer had benefit primarily as a result of the Viasystems acquisition. Because the primary determination of fair value was based on management’s assumptions and estimates of capitalized costs to dispose, the resulting fair value is considered a Level 3 input.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended
	Jan. 02, 2017
Commitments and Contingencies	(13) Commitments and Contingencies Operating Leases The Company leases some of its manufacturing and assembly plants, a sales office and equipment under noncancellable operating leases that expire at various dates through 2050. Certain real property leases contain renewal provisions at the Company’s option. Most of the leases require the Company to pay for certain other costs such as property taxes and maintenance. Certain leases also contain rent escalation clauses (step rents) that require additional rental amounts in the later years of the term. Rent expense for leases with step rents is recognized on a straight-line basis over the minimum lease term. The following is a schedule of future minimum lease payments as of January 2, 2017: Operating Leases (In thousands) 2017 $ 7,893 2018 4,375 2019 3,156 2020 2,351 2021 1,699 Thereafter 5,016 Total minimum lease payments $ 24,490 Total rent expense for the years ended January 2, 2017, December 28, 2015, and December 29, 2014, was approximately $10,329, $7,362 and $3,731, respectively. 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 January 2, 2017 and December 28, 2015. However, these amounts are not material to the consolidated 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 and Canada 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 2017 capital expenditure costs expected for these plans are included in the Company’s capital expenditure projections.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended
	Jan. 02, 2017
Stock-Based Compensation	(14) Stock-Based Compensation Incentive Compensation Plan The Company maintains a 2014 Incentive Compensation Plan (the Plan), which allowed for the issuance of up to 5,288 shares. In May 2016, the Plan was amended to increase the amount allowed for issuance by 5,000 shares, revising the maximum allowed for issuance to 10,288 through its expiration date of February 2024. The Plan provides for the grant of incentive stock options and nonqualified stock options to the Company’s key employees, non-employee non-employee As of January 2, 2017, 697 PRUs, 3,104 RSUs and 87 stock options were outstanding under the Plan. Included in the 697 PRUs outstanding as of January 2, 2017 are 291 vested but not yet released. Included in the 3,104 RSUs outstanding as of January 2, 2017 are 396 vested but not yet released RSUs associated with non-employee 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 may 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. Under the PRU program, financial goals are set at the beginning of each fiscal year and performance is reviewed at the end of that year. The percentage to be applied to each participant’s target award ranges from zero to 160% based upon the extent to which the annual financial performance goals are achieved. If specific performance threshold levels for the annual financial goals are met, the amount earned for that element will be applied to one-third At the end of the three-year performance period, the total units earned, if any, are adjusted by applying a modifier, ranging from zero to 150% based on the Company’s TSR based on stock price changes relative to a group of peer companies selected by the Company’s compensation committee for the same three-year period. The TSR modifier is intended to ensure that there are limited or no payouts under the PRU program if the Company’s stock performance is significantly below the median TSR of a group of peer companies selected by the Company’s compensation committee over the three-year performance period. Where the annual financial goals have been met and where there has been strong relative TSR performance over the three-year performance period, the PRU program may provide substantial rewards to participants with a maximum payout of 2.4 times the initial PRU award. However, even if all of the annual financial metric goals are achieved in each of the three years, there will be no payouts if the Company’s stock performance is below that of the 10th percentile for PRUs granted in 2016, and 20th percentile for PRUs granted prior to 2016, of the group of peer companies selected by the Company’s compensation committee, as appropriate. Recipients of PRU awards generally must remain employed by the Company on a continuous basis through the end of the three-year performance period in order to receive any amount of the PRUs covered by that award. In events such as death, disability or retirement, the recipient may be entitled to pro-rata 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. As of January 2, 2017, management determined that vesting of the PRU awards was probable. PRU activity for the year ended January 2, 2017 was as follows: Shares Weighted (In thousands) Outstanding target shares at December 28, 2015 301 $ 8.58 Granted 346 6.46 Vested (291 ) 6.01 Change in units due to annual performance achievement 50 6.08 Outstanding target shares at January 2, 2017 406 $ 8.31 The fair value of PRUs granted is calculated using a Monte Carlo simulation model, as the TSR modifier contains a market condition. For the years ended January 2, 2017, December 28, 2015 and December 29, 2014, the following assumptions were used in determining the fair value: For the Year Ended January 2, December 28, December 29, Weighted-average fair value $ 6.46 $ 7.22 $ 5.80 Risk-free interest rate 0.8 % 0.5 % 0.4 % Dividend yield — — — Expected volatility 40 % 37 % 41 % Expected term in months 24 22 23 (1) Reflects the weighted-averages for the third year of the three-year performance period applicable to PRUs granted in 2014, the second year of the three-year performance period applicable to PRUs granted in 2015 and the first year of the three-year performance period applicable to PRUs granted in 2016. (2) Reflects the weighted-averages for the third year of the three-year performance period applicable to PRUs granted in 2013, the second year of the three-year performance period applicable to PRUs granted in 2014 and the first year of the three-year performance period applicable to PRUs granted in 2015. (3) Reflects the weighted-averages for the third year of the three-year performance period applicable to PRUs granted in 2012, second year of the three-year performance period applicable to PRUs granted in 2013 and for the first year of the three-year performance period applicable to PRUs granted in 2014. The expected term of the PRUs reflects the performance period for the PRUs granted. Expected volatility is calculated using the Company’s historical stock price. The risk-free interest rate for the expected term of PRUs is based on the U.S Treasury yield curve in effect at the time of grant. Restricted Stock Units RSU activity for the year ended January 2, 2017 was as follows: Shares Weighted Grant-Date (In thousands) Non-vested 1,975 $ 8.77 Granted 1,827 6.78 Vested (906 ) 8.65 Forfeited (188 ) 8.59 Non-vested 2,708 $ 7.48 Vested and expected to vest at January 2, 2017 2,980 $ 7.79 The fair value of the Company’s RSUs is determined based upon the closing common stock price on the grant date. The weighted average fair value per unit of RSUs granted was $6.78, $9.15 and $7.98 for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively. The total fair value of RSUs vested for the years ended January 2, 2017, December 28, 2015 and December 29, 2014 was $7,834, $6,396 and $7,195, respectively. Stock Options During the year ended January 2, 2017, the Company granted 20 stock options to a newly appointed member of the board which were estimated to have a fair value per share of $6.78. No stock options were granted by the Company for the years ended December 28, 2015 or December 29, 2014. The fair value calculation is based on stock options granted during the period using the Black-Scholes option-pricing model on the date of grant. For the year ended January 2, 2017 the fair value was determined using 1.7% as the risk-free interest rate, 51% as the expected volatility, 8.5 years as the expected term and no dividend yield. The Company determines the expected term of its stock option awards by periodic review of its historical stock option exercise experience. This calculation considers pre-vesting Option activity under the Plan for the year ended January 2, 2017 was as follows: Options Weighted- Weighted- Aggregate (In thousands) (In years) (In thousands) Outstanding at December 28, 2015 420 $ 12.37 1.7 $ 4 Granted 20 11.83 Exercised (159 ) 10.97 Forfeited/expired (194 ) 14.08 Outstanding at January 2, 2017 87 $ 10.99 5.0 $ 228 Vested and expected to vest at January 2, 2017 87 $ 10.99 5.0 $ 228 Exercisable at January 2, 2017 67 $ 10.74 3.5 $ 192 The aggregate intrinsic values in the table above represent the total pretax intrinsic value (the difference between Company’s closing stock price on the last trading day of the 2016 fiscal year and the exercise price, multiplied by the number of in-the-money Stock-based Compensation Expense and Unrecognized Compensation Costs For the years ended January 2, 2017, December 28, 2015 and December 29, 2014, the amounts recognized in the consolidated financial statements with respect to the stock-based compensation plan are as follows: For the Year Ended January 2, December 28, December 29, (In thousands) Cost of goods sold $ 1,630 $ 1,117 $ 866 Selling and marketing 1,054 1,135 1,109 General and administrative 8,406 7,409 5,825 Stock-based compensation expense recognized 11,090 9,661 7,800 Income tax benefit recognized — — (2,018 ) Stock-based compensation expense recognized $ 11,090 $ 9,661 $ 5,782 The Company may become entitled to a deduction in its tax returns upon the future exercise of incentive stock options under certain circumstances; however, the value of this deduction will be recorded as an increase to additional paid-in paid-in The following is a summary of total unrecognized compensation costs as of January 2, 2017: Unrecognized Remaining Weighted (In thousands) (In years) RSU awards $ 11,822 1.3 PRU awards 1,631 1.5 Stock options 114 2.4 $ 13,567

In North America, the Company has a 401(k) savings plan (the Savings Plan) in which eligible full-time domestic employees can participate and contribute a percentage of compensation subject to the maximum allowed by the Internal Revenue Service. The Savings Plan provides for a partial match by the employer of the first 5% of employee contributions (100% of the first 3% and 50% of the following 2% of employee contributions). In China, the Company contributes to either separate trust-administered funds or various government-sponsored pension plans on a mandatory basis. For all retirement plans, the Company has no further payment obligation once the required contributions have been made. The Company recorded contributions to retirement benefit plans of $36,172, $35,427 and $18,953 during the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively. The Company also maintains a deferred compensation plan (the Compensation Plan).

For the year ended December 28, 2015, potential shares of common stock, consisting of stock options to purchase approximately 420 shares of common stock at exercise prices ranging from $5.78 to $16.82 per share, 2,294 RSUs, and 572 PRUs were not included in the computation of diluted earnings per share because the Company incurred a net loss from operations and, as a result, the impact would be anti-dilutive. Additionally, for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, the effect of shares of common stock related to the Company’s convertible senior notes were not included in the computation of dilutive earnings per share as the impact would be anti-dilutive. Outstanding warrants for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, to purchase common stock 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 year, and therefore, the effect would be anti-dilutive. The below is a summary of amounts convertible to common stock related to convertible senior notes and related warrants: For the Year Ended January 2, December 28, December 29, (In thousands) Common stock related to convertible senior notes 25,940 25,940 27,970 Warrants to purchase common stock 25,940 26,408 28,020

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 02, 2017
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Such estimates include the sales return reserve; accounts receivable; inventories; goodwill; intangible assets and other long-lived assets; self insurance reserves; product warranty liabilities; environmental liabilities; legal contingencies; income taxes; and others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. The actual results we experienced may differ materially and adversely from our estimates. To the extent there are material differences between the estimates and actual results, our future result of operations will be affected.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of TTM Technologies, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions The functional currency of certain of the Company’s subsidiaries is either the Chinese Renminbi (RMB) or the Hong Kong Dollar. Accordingly, assets and liabilities are translated into U.S. dollars using period-end
Cash Equivalents	Cash Equivalents The Company considers highly liquid investments with insignificant interest rate risk and original maturities to the Company of three months or less to be cash equivalents. Cash equivalents consist primarily of interest-bearing bank accounts and money market funds. The Company considers highly liquid investments with an effective maturity to the Company of more than three months and less than one year to be short-term investments. As of December 28, 2015, the Company had $3,530 of restricted cash related to the collaterization of certain letter of credit arrangements. As of January 2, 2017, all such letter of credit arrangements requiring collaterization had expired.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are reflected at estimated net realizable value, do not bear interest and do not generally require collateral. The Company performs credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness. The Company maintains an allowance for doubtful accounts based upon a variety of factors. The Company reviews all open accounts and provides specific reserves for customer collection issues when it believes the loss is probable, considering such factors as the length of time receivables are past due, the financial condition of the customer, and historical experience. The Company also records a reserve for all customers, excluding those that have been specifically reserved for, based upon evaluation of historical losses. The following summarizes the activity in the Company’s allowance for doubtful accounts for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Balance at beginning of year $ 1,525 $ 696 $ 518 Additions charged to expense 1,560 854 214 Deductions (223 ) (26 ) (34 ) Effect of foreign currency exchange rates (11 ) 1 (2 ) Balance at end of year $ 2,851 $ 1,525 $ 696
Inventories	Inventories Inventories are stated at the lower of cost (determined on a first-in, first-out
Property, Plant and Equipment, Net	Property, Plant and Equipment, Net Property, plant and equipment are recorded at cost. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Assets recorded under leasehold improvements are amortized using the straight-line method over the lesser of their useful lives or the related lease term. The Company uses the following estimated useful lives: Land use rights 50-99 years Buildings and improvements 7-50 years Machinery and equipment 3-12 years Furniture and fixtures 3-7 years Upon retirement or other disposition of property, plant and equipment, the cost and related accumulated depreciation are removed from the accounts. The resulting gain or loss is included in the determination of operating income in the period incurred. Depreciation and amortization expense on property, plant and equipment was $156,229, $133,508, and $95,349 for the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively. The Company capitalizes interest on borrowings during the active construction period of major capital projects. Capitalized interest is amortized over the average useful lives of such assets, which primarily consist of buildings and machinery and equipment. The Company capitalized interest costs of $1,876, $888, and $551 during the years ended January 2, 2017, December 28, 2015 and December 29, 2014, respectively, in connection with various capital projects. Major renewals and betterments are capitalized and depreciated over their estimated useful lives while minor expenditures for maintenance and repairs are included in operating income as incurred.
Goodwill	Goodwill Goodwill represents the excess of purchase price of an acquisition over the fair value of net assets acquired. Goodwill is not amortized but instead is assessed for impairment, at a reporting unit level, annually and when events and circumstances warrant an evaluation. In making this assessment, management relies on a number of factors, including expected future operating results, business plans, economic projections, anticipated future cash flows, business trends and market conditions. The Company has two reportable operating segments consisting of four reporting units. The Company evaluates its goodwill on an annual basis in the fourth quarter or more frequently if it believes indicators of impairment exist. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting units is less than its carrying amount, it conducts a two-step
Intangible Assets	Intangible Assets Intangible assets include customer relationships, technology and trade names, which are being amortized over their estimated useful lives using straight-line and accelerated methods. The estimated useful lives of such intangibles range from 3 years to 10 years.
Impairment of Long-lived Assets	Impairment of Long-lived Assets Long-lived tangible assets, including property, plant and equipment, assets held for sale, and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset or asset groups may not be recoverable. The Company regularly evaluates whether events or circumstances have occurred that indicate possible impairment and relies on a number of factors, including expected future operating results, business plans, economic projections, and anticipated future cash flows. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life in measuring whether the assets are recoverable. Measurement of the amount of impairment, if any, is based upon the difference between the asset’s carrying value and estimated fair value. Fair value is determined through various valuation techniques, including cost-based, market and income approaches as considered necessary. See Note 4 for information regarding the impairment of long-lived assets during the years 2016 and 2014. The Company classifies assets to be sold as assets held for sale when (i) Company management has approved and commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition and is ready for sale; (iii) an active program to locate a buyer and other actions required to sell the asset have been initiated; (iv) the sale of the asset is probable; (v) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Assets classified as held for sale are recorded at the lower of the carrying amount or fair value less the cost to sell and are a component of prepaid expenses and other current assets in the consolidated balance sheet. The Company classifies assets held for use when a decision to dispose of an asset or a business is made and the held for sale criteria are not met. Assets of the business are evaluated for recoverability in the following order: (i) assets other than goodwill, property and intangibles; (ii) property and intangibles subject to amortization; and (iii) goodwill. In evaluating the recoverability of property and intangible assets subject to amortization, in a held for use business, the carrying value is first compared to the sum of the undiscounted cash flows expected to result from the use and eventual disposition. If the carrying value exceeds the undiscounted expected cash flows, then a fair value analysis is performed. An impairment charge is recognized if the carrying value exceeds the fair value.
Revenue Recognition	Revenue Recognition The Company derives its revenue primarily from the sale of PCBs using customer supplied engineering and design plans and recognizes revenue when: (i) persuasive evidence of a sales arrangement exists; (ii) the sales terms are fixed or determinable; (iii) title and risk of loss have transferred; and (iv) collectability is reasonably assured — generally when products are shipped to the customer, except in situations in which title passes upon receipt of the products by the customer. In this case, revenues are recognized upon notification that customer receipt has occurred. The Company does not have customer acceptance provisions, but it does provide its customers a limited right of return for defective PCBs. The Company accrues an estimated amount for sales returns and allowances related to defective PCBs at the time of sale based on its ability to estimate sales returns and allowances using current and historical information. The reserve for sales returns and allowances is included as a reduction to revenue and accounts receivable, net. Shipping and handling fees and related freight costs and supplies associated with shipping products to customers are included as a component of cost of goods sold. Incremental warranty costs that are not related to sales returns are recorded in accrued expenses and cost of goods sold. The following summarizes the activity in the Company’s allowance for sales returns and allowances for the years ended January 2, 2017, December 28, 2015 and December 29, 2014: For the Year Ended January 2, December 28, December 29, (In thousands) Balance at beginning of year $ 7,789 $ 6,890 $ 6,028 Additions charged to expense 22,060 21,728 38,440 Deductions (21,728 ) (20,832 ) (37,578 ) Effect of foreign currency exchange rates (2 ) 3 — Balance at end of year $ 8,119 $ 7,789 $ 6,890
Stock-Based Compensation	Stock-Based Compensation The Company recognizes stock-based compensation expense in its consolidated financial statements for its incentive compensation plan awards. The incentive compensation plan awards include performance-based restricted stock units, restricted stock units, and stock options and the associated compensation expense is based on the grant date fair value of the awards, net of estimated forfeitures, as well as an assessment of probability of the performance-based awards vesting. Compensation expense for the incentive compensation plan awards is recognized on a straight line basis over the vesting period of the awards. The fair value of performance-based restricted stock units is estimated on the grant date using a Monte Carlo simulation model based on the underlying common stock closing price as of the date of grant, the expected term, stock price volatility, and risk-free interest rates. The fair value of restricted stock units is measured on the grant date based on the quoted closing market price of the Company’s common stock. The fair value of the stock options is estimated on the grant date using the Black-Scholes option pricing model based on the underlying common stock closing price as of the date of grant, the expected term, stock price volatility, and risk-free interest rates.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets or liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be settled or realized. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax assets are reviewed for recoverability, and the Company records a valuation allowance to reduce its deferred income tax assets when it is more likely than not that all or some portion of the deferred income tax assets will not be realized. The Company has various foreign subsidiaries formed or acquired to conduct or support its business outside the United States. The Company does not provide for U.S. income taxes on undistributed earnings for certain foreign subsidiaries as management expects the foreign earnings will be indefinitely reinvested in such foreign jurisdictions. For certain subsidiaries within China, indefinite investment of undistributed earnings has not been asserted between the respective subsidiaries and their foreign parent entity and therefore, a deferred tax liability for the foreign tax impacts has been recorded on the undistributed earnings of these subsidiaries. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Estimated interest and penalties related to underpayment of income taxes are recorded as a component of income tax provision in the consolidated statement of operations.
Self Insurance	Self Insurance The Company is primarily self insured in North America for group health insurance and workers compensation benefits provided to U.S. employees. The Company also purchases stop loss insurance to protect against annual claims per individual and at an aggregate level. The individual insured stop loss on the Company’s self insurance is $350 per individual for group health insurance and $250 per individual for worker’s compensation benefits. Self insurance liabilities are estimated for claims incurred but not paid based on judgment, using the Company’s historical claim data and information and analysis provided by actuarial and claim advisors, the Company’s insurance carrier and brokers. The Company has accrued $5,375 and $5,182 for self insurance liabilities as of January 2, 2017 and December 28, 2015, respectively, and these amounts are reflected within accrued salaries, wages and benefits in the consolidated balance sheets. Group health insurance and workers compensation benefits for the Company’s plants in China are fully insured with third parties.
Convertible Debt	Convertible Debt The accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion require the debt and equity components to be separately accounted for in a manner that reflects the Company’s nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to the Company’s at the time of issuance. The difference between the debt recorded at inception and its principal amount is to be accreted to principal through interest expense through the estimated life of the note.
Value Added and Sales Tax Collected from Customers	Value Added and Sales Tax Collected from Customers As a part of the Company’s normal course of business, value added and sales taxes are collected from customers. Such taxes collected are remitted, in a timely manner, to the appropriate governmental tax authority on behalf of the customer. The Company’s policy is to present revenue and costs, net of value added and sales taxes.
Fair Value Measures	Fair Value Measures The Company measures at fair value certain of its financial and non-financial Level 1 — Quoted market prices in active markets for identical assets or liabilities; Level 2 — Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable, such as interest rate and yield curves, and market-corroborated inputs); and Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting unit to develop its own assumptions.
Environmental Accrual	Environmental Accrual Accruals for estimated costs for environmental obligations generally are recognized no later than the date when the Company identifies what cleanup measures, if any, are likely to be required to address the environmental condition. Included in such obligations are the estimated direct costs to investigate and address the conditions, and the associated engineering, legal and consulting costs. In making these estimates, the Company considers information that is currently available, existing technology, enacted laws and regulations, and its estimates of the timing of the required remedial actions. Such accruals are initially measured on a discounted basis — and are adjusted as further information becomes available or circumstances change — and are accreted to the payable amount over time.
Earnings Per Share	Earnings Per Share Basic earnings per common share excludes dilution and is computed by dividing net income attributable to TTM Technologies, Inc. stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflect the potential dilution that could occur if stock options, convertible senior notes or other common stock equivalents were exercised or converted into common stock. The dilutive effect of stock options or other common stock equivalents is calculated using the treasury stock method, while the dilutive effect of convertible senior notes is calculated using the if-converted
Comprehensive Income	Comprehensive Income Comprehensive income includes changes to equity accounts that were not the result of transactions with stockholders. Comprehensive income is comprised of net income (loss), changes in the cumulative foreign currency translation adjustments and realized and unrealized gains or losses on hedged derivative instruments and available for sale securities.
Noncontrolling Interest Holdings	Noncontrolling As of January 2, 2017, noncontrolling interest consists of a 5% equity interest in a manufacturing facility in Huiyang, China which was acquired along with other assets and liabilities of Viasystems.
Loss Contingencies	Loss Contingencies The Company establishes an accrual for an estimated loss contingency when it is both probable that an asset has been impaired or that a liability has been incurred and the amount of the loss can be reasonably estimated. Any legal fees expected to be incurred in connection with a contingency are expensed as incurred.
Recently Adopted and Issued Accounting Standards	Recently Adopted and Issued Accounting Standards In October 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.
