Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	(1) Nature of Operations and Basis of Presentation TTM Technologies, Inc. (the Company or TTM) is a leading global printed circuit board (PCB) manufacturer, focusing on quick-turn and volume production of technologically complex PCBs and electro-mechanical solutions (E-M Solutions) as well as a global designer and manufacturer of high-frequency radio frequency (RF) and microwave components and assemblies. The Company provides time-to-market and volume production of advanced technology products and offers a one-stop manufacturing solution to customers from engineering support to prototype development through final mass production. This one-stop manufacturing solution enables the Company to align technology developments with the diverse needs of the Company’s customers and to enable them to reduce the time required to develop new products and bring them to market. The Company serves a diversified customer base in various markets throughout the world, including aerospace and defense, automotive components, smartphones and touchscreen tablets, high-end computing, medical, industrial and instrumentation related products, as well as networking/communications infrastructure products. The Company’s customers include both original equipment manufacturers (OEMs) and electronic manufacturing services (EMS) providers. The accompanying consolidated condensed financial statements have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. These consolidated condensed financial statements reflect all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial position, the results of operations and cash flows of the Company for the periods presented. It is suggested that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s most recent Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated condensed financial statements and accompanying notes. Actual results could differ materially from those estimates. The Company uses a 13-week fiscal quarter accounting period with the fourth quarter ending on the Monday nearest December 31. Recently Adopted and Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update ( Revenue from Contracts with Customers (Topic 606) The Company assessed the new guidance and adopted the new revenue standard on January 2, 2018, which resulted in a change to the timing of revenue recognition for certain of the Company’s revenue streams from “point in time” upon physical delivery to an “over time” model. Additionally, the Company elected the cumulative effect transition method with adjustment to the opening balance of retained earnings at January 2, 2018 for all open contracts as of January 1, 2018. Therefore, comparative information has not been adjusted and continues to be reported under previous U.S. GAAP guidance for the consolidated balance sheet at January 1, 2018 and the consolidated condensed statement of operations for the quarter and two quarters ended July 3, 2017. The cumulative effect of the changes made to the Company’s January 2, 2018 consolidated condensed balance sheet for the adoption of the new revenue standard was as follows: Balance at January 1, 2018 New Revenue Standard Adjustment Balance at January 2, 2018 (In thousands) Balance Sheet Assets Accounts receivable, net $ 483,903 $ 8,171 $ 492,074 Contract assets — 260,654 260,654 Inventories 294,588 (223,576 ) 71,012 Liabilities Other accrued expenses 114,685 13,384 128,069 Other long-term liabilities 74,667 3,291 77,958 Equity Retained earnings 193,342 28,574 221,916 As part of adoption of the new revenue standard, the Company recorded an estimated sales returns and allowance as well as a noncurrent deferred tax liability in the amount of $5,213 and $3,291, respectively, as of January 2, 2018. Additionally, the Company reclassified its sales returns and allowance balance of $8,171 as of January 1, 2018, from trade accounts receivable to other accrued liabilities. Sales returns and allowances are recorded as a reduction of revenue and a component of accrued liabilities on the condensed consolidated balance sheet. Additionally, the disclosure below summarizes the impact of the adoption of the new revenue standard on the Company’s consolidated condensed balance sheet as of July 2, 2018, statement of operations for the quarter and two quarters ended July 2, 2018 and statement of cash flows for the two quarters ended July 2, 2018 for which the As Reported Balances without New Revenue Standard Adjustment July 2, 2018 As reported Effect of Change Increase (Decrease) Balances without New Revenue Standard Adjustment (In thousands) Balance Sheet Assets Accounts receivable, net $ 541,587 $ 8,171 $ 533,416 Contract assets 300,717 293,114 7,603 Inventories 121,285 (245,895 ) 367,180 Liabilities Other accrued expenses 104,139 14,033 90,106 Other long-term liabilities 92,938 3,163 89,775 Equity Retained earnings 315,975 38,194 277,781 Quarter ended July 2, 2018 Two Quarters ended July 2, 2018 As reported Effect of Change Increase (Decrease) Balances without New Revenue Standard Adjustment As reported Effect of Change Increase Balances without New Revenue Standard Adjustment (In thousands) (In thousands) Net sales $ 716,887 $ 17,730 $ 699,157 $ 1,380,469 $ 31,811 $ 1,348,658 Cost of goods sold 600,747 (10,338 ) 611,085 1,175,651 22,319 1,153,332 Gross profit 116,140 7,392 108,748 204,818 9,492 195,326 Net income 84,004 7,392 76,612 94,101 9,620 84,481 Included in the Effect of Change Increase (Decrease) columns for the quarter and two quarters ended July 2, 2018 are $14,408, $11,375 and $3,033 of net sales, cost of goods sold and gross profit, respectively, related to the opening balance sheet of Anaren Inc. which was acquired on April 18, 2018 (See Note 3), Two Quarters ended July 2, 2018 As reported Effect of Change Increase (Decrease) Balances without New Revenue Standard Adjustment (In thousands) Cash flows from operating activities: Net income $ 94,101 $ 9,620 $ 84,481 Adjustments to reconcile net income to net cash used in operating activities: Deferred income taxes (64,769 ) (128 ) (64,641 ) Changes in operating assets and liabilities: Accounts receivable, net (17,056 ) — (17,056 ) Contract assets (16,478 ) (32,460 ) 15,982 Inventories 5,685 22,319 (16,634 ) Accrued salaries, wages and benefits and other accrued expenses (47,911 ) 649 (48,560 ) In August 2017, the FASB issued ASU 2017- Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842)

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Revenue Recognition The Company derives revenues primarily from the sale of PCBs, custom electronic assemblies using customer-supplied engineering and design plans. With the acquisition of Anaren Inc. (See Note 3), the Company now also derives revenue from the design, development, and manufacture of components, assemblies, and subsystems which receive, process, and transmit microwave and RF signals which service the aerospace and defense electronics, and wireless communications markets. The Company has three revenue streams which generally coincide with the Company’s reportable segments. These reportable segments are: PCB, E-M Solutions and Anaren. See Note 17 Segment Information. For the PCBs and custom electronic assemblies, orders for products generally correspond to the production schedules of the Company’s customers and are supported with firm purchase orders. The Company’s customers have continuous transfer of control of the work in progress and finished goods throughout the PCB manufacturing process, as PCBs are built to customer specifications and do not have an alternative use. The customer typically controls the work in progress and finished goods as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date, plus a reasonable profit. As a result, the Company records revenue in accordance with the “over time” revenue standard as discussed in Note 1 Nature of Operations and Basis of Presentation ─ Recently Adopted and Issued Accounting Standards , The selection of the method to measure progress toward completion requires judgment and is based on the type of PCB or customized electronic assemblies being manufactured. The Company uses the cost-to-cost method as it best depicts the transfer of control to the customer which takes place as we incur costs. Under the cost-to-cost measure of progress, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Additionally, the Company has certain long-term contracts related to its manufacture of components, assemblies, and subsystems which service the aerospace and defense electronics market. These long-term contracts, many of which provide for periodic payments, are recognized over time under the percentage-of completion method. Estimated manufacturing cost-at-completion for these contracts are reviewed on a periodic basis, and adjustments are made periodically to the estimated cost-at-completion, based on actual costs incurred, progress made, and estimates of costs required to complete the contractual requirements. When the estimated manufacturing cost-at-completion exceeds the contract value, the contract is written down to its net realizable value and the loss resulting from the cost overruns are immediately recognized. Finally, the Company manufactures components, assemblies, and subsystems which service its wireless communications customers. The Company recognizes revenue at a point in time as the customer does not simultaneously receive or consume the benefits provided by the Company’s performance and the asset being manufactured has alternative uses to the Company. The Company provides customers a limited right of return for defective PCBs, assemblies, components and subsystems. The Company accrues an estimate for sales returns and allowances progressively over time based on the extent of progress towards completion of the performance obligation using the Company’s judgment based on historical results and anticipated returns. To the extent actual experience varies from its historical experience, revisions to the sales returns and allowances accrual may be required. Sales returns and allowances are recorded as a reduction of revenue and included as a component of accrued liabilities on the condensed consolidated balance sheet.

Acquisition of Anaren Inc.

Acquisition of Anaren Inc.	6 Months Ended

Business Combinations [Abstract]
Acquisition of Anaren Inc.	(3) Acquisition of Anaren Inc. On April 18, 2018, the Company completed its acquisition of all issued and outstanding common stock of Anaren Holding Corp. for a total consideration of $787,911 subject to customary working capital and certain other adjustments. Other than the equity interests of Anaren, Inc. (Anaren), Anaren Holding Corp. had no material assets or liabilities and has no material independent operations. Anaren is a leading provider of mission-critical RF solutions, microelectronics, and microwave components and assemblies for the wireless infrastructure and aerospace and defense electronics markets. For the quarter and two quarters ended July 2, 2018, bank fees and legal, accounting, and other professional service costs associated with the acquisition of $6,852 and $10,825, respectively, have been expensed and recorded as general and administrative expense in the consolidated condensed financial statements. There were no bank fees or legal, accounting, or other professional service costs associated with the acquisition for the quarter and two quarters ended July 3, 2017. The following summarizes the components of the purchase price: (In thousands) Cash consideration $ 596,396 Cash purchased 12,911 609,307 Debt assumed 178,604 Total consideration $ 787,911 Preliminary Purchase Price Allocation The purchase price was allocated to tangible and intangible assets acquired, and liabilities assumed based on preliminary estimates of fair value at the date of the acquisition, April 18, 2018. The excess of the purchase price over the fair value of net assets acquired was allocated to goodwill. The fair value assigned to identifiable intangible assets acquired was based on estimates and assumptions made by management at the time of the acquisition. The fair values assigned are based on reasonable methods applicable to the nature of the assets acquired and liabilities assumed. The following summarizes the preliminary estimated fair values of net assets acquired: (In thousands) Cash $ 12,911 Trade and notes receivables 32,457 Contract assets 23,585 Inventories 55,958 Other current assets 1,673 Property, plant and equipment 47,329 Identifiable intangible assets 337,000 Goodwill 386,278 Trade accounts payable (14,629 ) Contract liabilities (7,778 ) Other current liabilities (3,757 ) Long-term debt (178,604 ) Non-current deferred tax liabilities (75,123 ) Other liabilities (7,993 ) Total $ 609,307 Due to the fact that the acquisition occurred in the current interim period, the Company’s fair value estimates for the purchase price allocation are preliminary and may change during the allowable measurement period, which is up to the point the Company obtains and analyzes the information that existed as of the date of the acquisition necessary to determine the fair values of the assets acquired and liabilities assumed, but in no case to exceed more than one year from the date of acquisition. As of July 2, 2018, the Company had not finalized the determination of fair values allocated to various assets and liabilities, including, but not limited to, property, plant and equipment, identifiable intangible assets, other assets, deferred taxes, goodwill, tax uncertainties, income taxes payable and liabilities assumed. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in material adjustments to goodwill. Inventories The Company acquired $55,958 of inventories as a result of the acquisition. Finished goods were preliminarily valued at estimated selling prices less costs of disposal and a reasonable profit allowance for the selling effort. Work-in-process inventory was valued at estimated selling prices less costs to complete, costs of disposal and a reasonable profit allowance for the completion and selling effort. Raw materials were preliminarily valued at estimated replacement cost. Property, Plant and Equipment The fair value of property, plant and equipment was preliminarily determined by utilizing three approaches: the cost, sales comparison, and income capitalization approaches, each including management assumptions. Each approach assumes valuation of the property at the property’s highest and best use. Identifiable Intangible Assets Acquired identifiable intangible assets include customer relationships, developed technology and backlog. The fair value of the identifiable intangible assets was preliminarily determined using various income approach methods including excess earnings to determine the present value of expected future cash flows for each identifiable intangible asset based on discount rates which incorporate a risk premium to take into account the risks inherent in those expected cash flows. The expected cash flows were estimated using available historical data adjusted based on the Company’s historical experience and the expectations of market participants. The preliminary estimated fair value assigned to each class of intangible assets and the related weighted average amortization periods are as follows: Estimated fair value Weighted- average amortization period (In thousands) Customer relationships $ 268,000 12.2 years Developed technology 39,500 9.4 years Backlog 29,500 0.9 years $ 337,000 Goodwill Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. Prior to the Company’s acquisition of Anaren, the Company had two reportable segments: PCB and E-M Solutions. Due to the acquisition, the Company has reassessed its reportable segments and determined that it has three reportable segments: PCB, E-M Solutions and Anaren. However, beginning in the third quarter of 2018, the Company will no longer report Anaren as a reportable segment as the Company will integrate it into the PCB reportable segment. The excess purchase price over the fair value of assets acquired and liabilities assumed has been completely allocated to the Anaren reportable segment. The Company believes that the acquisition of Anaren will produce the following significant benefits: • Provide the Company with differentiated RF expertise in aerospace and defense and embedded technology that the Company believes is critical to wireless infrastructure markets. • Augment the Company’s strong aerospace and defense position and provide new opportunities for growth in the automotive and optical networking market. • Deepen the Company’s engagement and interaction with leading customers in the aerospace and defense and wireless communication infrastructure markets. • Strengthen the Company’s management and engineering teams with the addition of talented members having extensive experience in RF design; The Company believes that these primary factors support the amount of goodwill recognized as a result of the purchase price paid for Anaren, in relation to other acquired tangible and intangible assets. The goodwill acquired in the acquisition is not deductible for income tax purposes. Results of Operations Included in the consolidated condensed statements of operations for the quarter and two quarters ended July 2, 2018 are net sales of $62,011, excluding intercompany sales, and pre-tax net income of $13,307 from the Anaren operations.

The U.S. ABL consists of three tranches comprised of a revolving credit facility for up to $200,000, a letter of credit facility for up to $50,000, and swingline loans for 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 July 2, 2018, the interest rate on the outstanding borrowings under the U.S. ABL was 3.60%. 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 certain inventories as well as by a second position against a significant amount of the domestic assets of the Company and a pledge of 65% of the voting stock of the Company’s first tier foreign subsidiaries and are structurally senior to the Company’s Senior Notes and Convertible Senior Notes.

Income Tax Disclosure [Abstract]
Income Taxes	(9) Income Taxes The Company’s effective tax rate is impacted by tax rates in China and Hong Kong, the U.S. federal income tax rate, apportioned state income tax rates, generation of other credits and deductions available to the Company as well as changes in valuation allowances and certain non-deductible items. During the quarter and two quarters ended July 2, 2018, the Company’s effective tax rate was impacted by a net discrete benefit of $67,309 and $66,429, respectively. This is related to accrued interest expense on existing uncertain tax positions, tax incentives, release of uncertain tax positions due to the expiration of the statute of limitations in foreign jurisdictions, release of a portion of the Company’s valuation allowance against its U.S. federal and state net deferred tax assets, and an additional expense related to the non U.S. income tax effect of a change in assertion with respect to the Company’s indefinite reinvestment policy outside of the U.S. Additionally, no tax benefit was recorded on the losses incurred in certain foreign jurisdictions as a result of corresponding increases in the valuation allowances in these jurisdictions. During the quarter ended July 2, 2018, the Company recorded a discrete tax benefit of $74,599 (included in the net amount reported in the previous paragraph) related to the release of a portion of the Company’s valuation allowance against its U.S. federal and state net deferred tax assets as a result of the net deferred tax liability established with the acquisition of Anaren. The Company expects its earnings attributable to foreign subsidiaries will be indefinitely reinvested outside of the U.S. but to facilitate more efficient cash management outside of the U.S., the Company has revised its assertion such that a majority of foreign earnings can be repatriated up to the top tier foreign holding company and as such, has provided for an additional accrual of deferred tax liabilities as a discrete tax expense of $9,963 (also included in the net amount reported in the previous paragraph) for the quarter ended July 2, 2018. The Company continues to maintain its indefinite reinvestment of earnings attributable to foreign subsidiaries with respect to the U.S. and, therefore, no deferred tax liabilities for U.S. income taxes on undistributed earnings are recorded. Effects of the Tax Cuts and Jobs Act On December 22, 2017, the Tax Cuts and Jobs Act (Tax Act) was enacted. Accounting Standard Codification (ASC) 740, Accounting for Income Taxes Given the timing of enactment of the Tax Act and the significance of the legislation, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period” similar to that used when accounting for business combinations. However, the measurement period should not extend beyond one year from the Tax Act enactment date and is deemed to have ended when the registrant has obtained, prepared and analyzed the information necessary to finalize its accounting. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. More specifically, SAB 118 summarizes a three-step process to be applied at each reporting period to account for and disclose the tax effects of the Tax Act. The steps are (1) to record the effects of the change in tax law for which accounting is complete; (2) to record provisional amounts (or adjustments to provisional amounts) for the effects of the tax law where accounting is not complete, but for which a reasonable estimate has been determined; and (3) where a reasonable estimate cannot yet be made, to continue to apply ASC 740 based on the tax law in effect prior to enactment of the Tax Act. Amounts recorded where accounting is complete for the year ended January 1, 2018 primarily relate to the reduction in the U.S. corporate income tax rate to 21 percent. The Company revalued its ending gross deferred tax items, previously recorded at 35 percent, using the enacted 21 percent corporate tax rate. This change caused a reduction to the Company’s U.S. federal deferred tax assets fully offset by a reduction of its valuation allowance. Effects of tax law changes where a reasonable estimate of the accounting effects cannot yet been made include the one-time mandatory repatriation transition tax on the net accumulated earnings and profits of the Company’s foreign subsidiaries earned post 1986. For the year ended January 1, 2018, the Company had performed a preliminary earnings and profits analysis with consideration given to foreign loss carryforwards acquired as a result of the Company’s acquisitions and determined on a provisional basis that there should be no income tax effect in the current or any future period. For the quarter and two quarters ended July 2, 2018, the Company has continued to gather documentation to support its position and maintains that there should be no income tax effect. The Company has determined that the following provisions that are effective January 1, 2018 and relevant to the Company will not impact the quarter and two quarters ended July 2, 2018 tax expense, primarily as a result of the full valuation allowance in the U.S.: limitations on certain entertainment expenses, the inclusion of commissions and performance based compensation in determining the excessive compensation limitation, limitation on the current deductibility of net interest expense in excess of 30 percent of adjusted taxable income, and a minimum tax on certain foreign earnings in excess of 10 percent of the foreign subsidiaries tangible assets (i.e., global intangible low-taxed income or GILTI). The Company has decided to make a policy election to treat the GILTI tax as a period expense and as such, no U.S. deferred taxes will be calculated on foreign earnings that are expected to generate GILTI income when they reverse in future years. For the quarter and two quarters ended July 2, 2018, other than as noted above, the Company has not made any changes to its previously provisional estimate of the impact U.S. Tax Reform and the Company continues to analyze and model the impact and will record said impact as it becomes more certain. This includes the mandatory repatriation tax and the indefinite criterion assertion on foreign earnings (with respect to repatriation to the U.S.).

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Financial Instruments	(10) Financial Instruments Derivatives Interest Rate Swaps The Company’s business is exposed to interest rate risk resulting from fluctuations in interest rates on certain LIBOR-based variable rate debt. Increases in interest rates would increase interest expenses relating to the outstanding variable rate borrowings and increase the cost of debt. Fluctuations in interest rates can also lead to significant fluctuations in the fair value of the debt obligations. On May 15, 2018, the Company entered into a four-year pay-fixed, receive floating (1-month LIBOR), interest rate swap arrangement with a notional amount of $400,000 for the period beginning June 1, 2018 and ending on June 1, 2022. Under the terms of the interest rate swap, the Company would pay a fixed rate of 2.84% against the first interest payments of a portion of its LIBOR-based debt and would receive floating 1-month LIBOR during the swap period. During the quarter ended July 2, 2018, the Company designated this interest rate swap as a cash flow hedge. At inception, the fair value of the interest rate swap was zero. As of July 2, 2018, the fair value of the interest rate swap was recorded as a liability in the amount of $1,416 and included as a component of other accrued liabilities. The change in the fair value of the interest rate swap is recorded as a component of accumulated other comprehensive income, net of tax, in the Company’s consolidated condensed balance sheet. No ineffectiveness was recognized for the quarter ended July 2, 2018. During the quarter ended July 2, 2018, the interest rate swap increased interest expense by $303. Foreign Exchange Contracts The Company enters into foreign currency forward contracts to mitigate the impact of changes in foreign currency exchange rates and to reduce the volatility of purchases and other obligations generated in currencies other than the functional currencies. The Company’s foreign subsidiaries may at times purchase forward exchange contracts to manage their foreign currency risks in relation to certain purchases of machinery denominated in foreign currencies other than the Company’s functional currency. The notional amount of the foreign exchange contracts at July 2, 2018 and January 1, 2018 was approximately $6,482 and $10,927, respectively. The Company has designated certain of these foreign exchange contracts as cash flow hedges.

Risks And Uncertainties [Abstract]
Significant Customers and Concentration of Credit Risk	(12) Significant Customers and Concentration of Credit Risk In the normal course of business, the Company extends credit to its customers. Most customers to which the Company extends credit are located outside the United States. 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 two quarters ended July 2, 2018, one customer accounted for approximately 12% of the Company’s net sales. There were no customers that accounted for 10% or more of net sales for the quarter ended July 2, 2018. For both the quarter and two quarters ended July 3, 2017 July July 3, 2017

Fair Value Disclosures [Abstract]
Fair Value Measures	(13) 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 July July 2, 2018 January 1, 2018 Carrying Amount Fair Value Carrying Amount Fair Value (In thousands) Derivative assets, current $ — $ — $ 107 $ 107 Derivative liabilities, current 1,565 1,565 258 258 Term Loan due September 2024 932,805 943,515 344,646 346,943 Senior Notes due October 2025 368,568 366,829 368,218 384,769 Convertible Senior Notes 223,225 474,547 218,274 429,199 ABL Revolving Loans 70,000 70,000 47,000 47,000 Capital lease 1,556 1,556 1,919 1,919 The fair value of the derivative instruments was determined using pricing models developed based on the LIBOR swap rate, foreign currency exchange rates, and other observable market data, including quoted market prices, as appropriate using Level 2 inputs. The values were adjusted to reflect nonperformance risk of both the counterparty and the Company, as necessary. 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 July 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 July July 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 (or are tested at least annually in the case of goodwill) such that a non-financial instrument is required to be evaluated for impairment, 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. See Note 3 for discussion of the fair value measurement of assets acquired and liabilities assumed in the Anaren acquisition.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(14) 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 July 2, 2018 and January 1, 2018. 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 regulations as well as 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 has established and enacted an investment plan related to the efforts to come into full compliance with the new regulations. The 2018 capital expenditure costs expected for these plans are included in the Company’s capital expenditure projections.

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 annual financial performance goals to be achieved. For the two quarters ended July 2, 2018, management determined that vesting of the PRU awards was probable. PRUs activity for the two quarters ended July 2, 2018 was as follows: Shares Weighted Average Fair Value (In thousands) Outstanding target shares at January 1, 2018 409 $ 16.39 Granted 334 19.59 Change in units due to annual performance achievement (22 ) 19.59 Outstanding target shares at July 2, 2018 721 $ 17.77 Restricted Stock Units The Company granted 195 and 61 RSUs during the quarters ended July 2, 2018 and July 3, 2017, respectively, and 1,023 and 1,007 RSUs during the two quarters ended July 2, 2018 and July 3, 2017, respectively. The RSUs granted have a weighted-average fair value per unit of $16.06 and $16.52 for the quarters ended July 2, 2018 and July 3, 2017, respectively, and $15.44 and $15.82 for the two quarters ended July 2, 2018 and July 3, 2017, 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. Stock Options During the quarter and two quarters ended July 2, 2018, The Company granted 20 stock option awards to a newly appointed member of the board which were estimated to have a fair value per share of $8.92. 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 quarter and two quarters ended July 2, 2018, the fair value was determined using 3.0% as the risk-free interest rate, 43.0% as the expected volatility, 8.5 years as the expected term and no dividend yield. The Company did not grant stock option awards during the quarter and two quarters ended July 3, 2017.

Segment Reporting [Abstract]
Segment Information	(17) Segment Information The reportable 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 three reportable segments: PCB, E-M Solutions and Anaren. However, beginning in the third quarter of 2018, the Company will no longer report Anaren as a reportable segment as the Company will integrate it into the PCB reportable segment. The PCB reportable segment is comprised of multiple 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 reportable 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. All inter-segment transactions have been eliminated. The inter-segment sales for the quarter and two quarters ended July 2, 2018 and July 3, 2017, are sales primarily from the PCB to the E-M Solutions reportable segment.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recently Adopted and Issued Accounting Standards	Recently Adopted and Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update ( Revenue from Contracts with Customers (Topic 606) The Company assessed the new guidance and adopted the new revenue standard on January 2, 2018, which resulted in a change to the timing of revenue recognition for certain of the Company’s revenue streams from “point in time” upon physical delivery to an “over time” model. Additionally, the Company elected the cumulative effect transition method with adjustment to the opening balance of retained earnings at January 2, 2018 for all open contracts as of January 1, 2018. Therefore, comparative information has not been adjusted and continues to be reported under previous U.S. GAAP guidance for the consolidated balance sheet at January 1, 2018 and the consolidated condensed statement of operations for the quarter and two quarters ended July 3, 2017. The cumulative effect of the changes made to the Company’s January 2, 2018 consolidated condensed balance sheet for the adoption of the new revenue standard was as follows: Balance at January 1, 2018 New Revenue Standard Adjustment Balance at January 2, 2018 (In thousands) Balance Sheet Assets Accounts receivable, net $ 483,903 $ 8,171 $ 492,074 Contract assets — 260,654 260,654 Inventories 294,588 (223,576 ) 71,012 Liabilities Other accrued expenses 114,685 13,384 128,069 Other long-term liabilities 74,667 3,291 77,958 Equity Retained earnings 193,342 28,574 221,916 As part of adoption of the new revenue standard, the Company recorded an estimated sales returns and allowance as well as a noncurrent deferred tax liability in the amount of $5,213 and $3,291, respectively, as of January 2, 2018. Additionally, the Company reclassified its sales returns and allowance balance of $8,171 as of January 1, 2018, from trade accounts receivable to other accrued liabilities. Sales returns and allowances are recorded as a reduction of revenue and a component of accrued liabilities on the condensed consolidated balance sheet.

Revenue Recognition	Revenue Recognition The Company derives revenues primarily from the sale of PCBs, custom electronic assemblies using customer-supplied engineering and design plans. With the acquisition of Anaren Inc. (See Note 3), the Company now also derives revenue from the design, development, and manufacture of components, assemblies, and subsystems which receive, process, and transmit microwave and RF signals which service the aerospace and defense electronics, and wireless communications markets. The Company has three revenue streams which generally coincide with the Company’s reportable segments. These reportable segments are: PCB, E-M Solutions and Anaren. See Note 17 Segment Information. For the PCBs and custom electronic assemblies, orders for products generally correspond to the production schedules of the Company’s customers and are supported with firm purchase orders. The Company’s customers have continuous transfer of control of the work in progress and finished goods throughout the PCB manufacturing process, as PCBs are built to customer specifications and do not have an alternative use. The customer typically controls the work in progress and finished goods as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date, plus a reasonable profit. As a result, the Company records revenue in accordance with the “over time” revenue standard as discussed in Note 1 Nature of Operations and Basis of Presentation ─ Recently Adopted and Issued Accounting Standards , The selection of the method to measure progress toward completion requires judgment and is based on the type of PCB or customized electronic assemblies being manufactured. The Company uses the cost-to-cost method as it best depicts the transfer of control to the customer which takes place as we incur costs. Under the cost-to-cost measure of progress, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Additionally, the Company has certain long-term contracts related to its manufacture of components, assemblies, and subsystems which service the aerospace and defense electronics market. These long-term contracts, many of which provide for periodic payments, are recognized over time under the percentage-of completion method. Estimated manufacturing cost-at-completion for these contracts are reviewed on a periodic basis, and adjustments are made periodically to the estimated cost-at-completion, based on actual costs incurred, progress made, and estimates of costs required to complete the contractual requirements. When the estimated manufacturing cost-at-completion exceeds the contract value, the contract is written down to its net realizable value and the loss resulting from the cost overruns are immediately recognized. Finally, the Company manufactures components, assemblies, and subsystems which service its wireless communications customers. The Company recognizes revenue at a point in time as the customer does not simultaneously receive or consume the benefits provided by the Company’s performance and the asset being manufactured has alternative uses to the Company. The Company provides customers a limited right of return for defective PCBs, assemblies, components and subsystems. The Company accrues an estimate for sales returns and allowances progressively over time based on the extent of progress towards completion of the performance obligation using the Company’s judgment based on historical results and anticipated returns. To the extent actual experience varies from its historical experience, revisions to the sales returns and allowances accrual may be required. Sales returns and allowances are recorded as a reduction of revenue and included as a component of accrued liabilities on the condensed consolidated balance sheet.
