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 provider of time-critical and technologically complex printed circuit board (PCB) products and backplane assemblies (PCBs populated with electronic components), which serve as the foundation of sophisticated electronic products. The Company provides advanced technology products and offers a one-stop manufacturing solution to customers from engineering support to prototype development through final volume production. The Company serves a diversified customer base in various markets throughout the world, including manufacturers of networking/communications infrastructure products, touch screen tablets and smartphones. The Company also serves aerospace and defense, high-end computing, and industrial/medical industries. 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 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. generally accepted accounting principles 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 Issued Accounting Standards
	On May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. (ASU) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company at the beginning of fiscal year 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	In July 2013, the FASB issued an update that would require an unrecognized tax benefit, or a portion of an unrecognized benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. This update is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The Company adopted the amendment on January 1, 2014, and its adoption did not have a material impact on its financial statements.

	(2) Acquisition of Viasystems Group, Inc.
	On September 21, 2014, TTM, Viasystems Group, Inc. (Viasystems), and Vector Acquisition Corp. (Merger Sub) entered into an Agreement and Plan of Merger (the Merger Agreement) under which TTM will acquire all outstanding shares of Viasystems (the Merger) for a combined consideration of $11.33 in cash and 0.706 shares of TTM common stock per outstanding share of Viasystems common stock, which based on the closing market price on September 19, 2014 was valued at $16.46 per share of Viasystems common stock, or approximately $368 million. The total enterprise value of the transaction, including the assumption of debt, is approximately $927 million which was based on the closing market price on September 19, 2014 and is subject to change prior to the consummation of the Merger.
	The Merger Agreement provides that Viasystems is entitled to receive a reverse breakup fee of $40 million from TTM in the event that the Merger Agreement is terminated following specific conditions.
	On September 30, 2014, in conjunction with TTM’s announcement of the execution of a definitive agreement with Viasystems, TTM was named in a class action complaint filed in the Circuit Court of St. Louis County, Missouri. On October 13, 2014, TTM was named in a similar class action complaint filed in the Court of Chancery of the State of Delaware. Both suits were filed on behalf of the public stockholders of Viasystems against Viasystems’ board of directors for breaches of fiduciary duties arising out of their attempt to sell Viasystems to TTM, and against TTM for aiding and abetting such breaches of fiduciary duties. TTM cannot assess the potential outcomes of these class action complaints at this time. See Note 12 to these Consolidated Condensed Financial Statements for additional information.
	Bank fees and legal and accounting costs associated with the acquisition of Viasystems of $1,632 for the quarter ended September 29, 2014 have been expensed and recorded as general and administrative expense in the consolidated condensed statement of operations in accordance with ASC Topic 805, Business Combinations.
	The transaction is expected to close in the first half of 2015.

	(4) Impairment of Long-Lived Assets
	In conjunction with the closure of its Suzhou, China manufacturing facility in 2013, the Company determined that certain long-lived assets, primarily consisting of held for sale machinery and equipment, were impaired. As a result, the Company recorded a charge for the impairment of long-lived assets in the amount of $10,782 for the quarter and three quarters ended September 30, 2013 and reclassified such assets to assets held for sale, which were included in other current assets in the December 30, 2013 consolidated condensed balance sheet.
	During the three quarters ended September 29, 2014, the Company recorded an impairment charge for additional assets, related to the closure of the Suzhou, China manufacturing facility, which were originally designated to be transferred to other facilities in China as well as the disposal of a substantial portion of the assets held for sale. As a result, the Company recognized an additional impairment charge in the amount of $1,845 during the three quarters ended September 29, 2014, as the carrying value of the assets was greater than the market value at the date of disposal.

	Credit Agreement
	In 2012, the Company became a party to a facility agreement (Credit Agreement) consisting of a $370,000 senior secured term loan (Term Loan), a $90,000 senior secured revolving loan (Revolving Loan), and a secured $80,000 letters of credit facility (Letters of Credit Facility). The Term Loan and Letters of Credit Facility will mature on September 14, 2016. The Revolving Loan will mature on March 14, 2016. The Credit Agreement is secured by substantially all of the assets of the Company’s Asia Pacific operating segment and is senior to all other debt, including the convertible senior notes. See Note 6 to these Consolidated Condensed Financial Statements for additional information. The Company has fully and unconditionally guaranteed the full and timely payment of all Credit Agreement related obligations of its Asia Pacific operating segment.
	As of September 29, 2014 and December 30, 2013, the remaining unamortized debt issuance costs included in other non-current assets was $1,323 and $1,937, respectively, and is amortized to interest expense over the term of the Company’s Credit Agreement using the effective interest rate method. At September 29, 2014, the remaining amortization period for the unamortized debt issuance costs was 1.7 years.
	The Company is also required to pay a commitment fee of 0.50% per annum on any unused portion of the loan and letters of credit facility granted under the Credit Agreement. The Company incurred commitment fees related to unused borrowing availability of $155 and $129 for the quarters ended September 29, 2014 and September 30, 2013, respectively, and $439 and $320 for the three quarters ended September 29, 2014 and September 30, 2013, respectively. As of September 29, 2014, the outstanding amount of the Term Loan under the Credit Agreement was $273,800, of which $96,200 is due for repayment through September 2015 and is included as short-term debt, with the remaining $177,600 included as long-term debt. None of the Revolving Loan was outstanding under the Credit Agreement as of September 29, 2014. Available borrowing capacity under the Revolving Loan was $90,000 at September 29, 2014.
	Other Credit Facility
	Additionally, the Company is party to a revolving loan credit facility with a lender in the People’s Republic of China (China). Under this arrangement, the lender has made available to the Company approximately $47,300 in unsecured borrowing with all terms of the borrowing to be negotiated at the time the revolver is drawn upon. There are no commitment fees on the unused portion of the revolver and this arrangement expires in December 2014. As of September 29, 2014, the revolver had not been drawn upon.
	Letters of Credit
	The Company has an $80,000 Letters of Credit Facility under the Credit Agreement, as mentioned above. As of September 29, 2014, letters of credit in the amount of $43,234 were outstanding under this Credit Agreement. The Company has other standby letters of credit outstanding in the amount of $3,894, which expire between December 31, 2014 and February 28, 2015.

	(6) Convertible Senior Notes
	Convertible Senior Notes due 2020
	In December 2013, the Company issued 1.75% convertible senior notes due December 15, 2020, in a public offering for an aggregate principal amount of $220,000. 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 senior in right of payment to any of the Company’s future subordinated indebtedness.
	In January 2014, the Company closed the sale of an additional $30,000 aggregate principal amount of its 1.75% convertible senior notes due 2020 (Additional Notes). The Additional Notes were sold pursuant to the exercise of an over-allotment option granted by the Company in the underwriting agreement related to the offer and sale of $220,000 aggregate principal amount of its 1.75% convertible senior notes due 2020.
	In connection with the offering of the Additional Notes, the Company entered into additional convertible note hedge and warrant transactions (Additional Call Spread Transaction) with respect to shares of its common stock. The additional convertible note hedge, which cost an aggregate $7,953 and was recorded, net of tax, as a reduction of additional paid-in capital, consists of the Company’s option to purchase up to 3,100 common stock shares at a price of $9.64 per share and will expire upon the maturity of the notes. Additionally, the Company sold warrants to purchase 3,100 shares of its common stock at a price of $14.26 per share. The warrants expire ratably from March 2021 through January 2022. The proceeds from the sale of warrants of $4,053 was recorded as an increase to additional paid-in capital. The 2020 Additional Call Spread Transaction has no effect on the terms of the convertible senior notes due 2020 and reduces potential dilution by effectively increasing the conversion price of the convertible senior notes due 2020 to $14.26 per share of the Company’s common stock.
	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.
	Convertible Senior Notes due 2015
	In May 2008, the Company issued 3.25% convertible senior notes due May 15, 2015, in a public offering for an aggregate principal amount of $175,000. The convertible senior notes bear interest at a rate of 3.25% per annum. Interest is payable semiannually in arrears on May 15 and November 15 of each year. The convertible senior notes are senior unsecured obligations and rank equally to the Company’s future unsecured senior indebtedness and senior in right of payment to any of the Company’s future subordinated indebtedness.
	In January 2014, the Company repurchased $6,514 of notes at approximately 103.4% of their principal amount. The repurchase of the convertible senior notes was accounted for as an extinguishment of debt, and accordingly, the Company recognized a $506 loss primarily associated with the premium paid to repurchase the convertible senior notes and the recognition of certain remaining unamortized debt discount and issuance costs.
	The maximum number of shares issuable upon conversion, including the effect of a fundamental change and subject to Other Conversion Rate Adjustments, would be 2,587.
	As of September 29, 2014 and December 30, 2013, the following summarizes the liability and equity components of the convertible senior notes:

	For the quarter and three quarters ended September 29, 2014, the amortization of debt discount and debt issuance costs for the 2020 convertible senior notes and the 2015 convertible senior notes is based on an effective interest rate of 6.48% and 8.37%, respectively. For the quarter and three quarters ended September 30, 2013, the amortization of debt discount and debt issuance costs for the 2015 convertible senior notes is based on an effective interest rate of 8.37%.

	(7) Income Taxes
	The Company’s provision for income taxes was $379 and $3,365 for the quarters ended September 29, 2014 and September 30, 2013, respectively. Additionally, the Company had an income tax benefit of $968 for the three quarters ended September 29, 2014 and a provision for income taxes of $13,494 for the three quarters ended September 30, 2013. The Company’s provision for income taxes reflects the benefits of earnings from the Company’s operations in lower-tax jurisdictions in China, the apportioned state income tax rates, generation of other credits and deductions, and certain non-deductible items.
	During the quarter ended September 29, 2014, the Company’s provision for income taxes was impacted by losses incurred in certain foreign jurisdictions for which no tax benefit was recorded as a result of full valuation allowances. In addition, the Company recorded discrete tax benefits resulting from the research and development deduction at a Chinese subsidiary within the Company’s Asia Pacific operating segment and changes in estimates resulting from the completion of the Company’s 2013 federal income tax return. During the three quarters ended September 29, 2014, the Company’s provision for income taxes was further impacted by a discrete tax benefit resulting from the retroactive approval of the high technology enterprise status for certain Chinese subsidiaries within the Company’s Asia Pacific operating segment.
	The Company’s provision for income taxes for the quarter and three quarters ended September 30, 2013 was impacted by the impairment of property, plant and equipment related to a plant closure in China which resulted in no related tax benefit. Additionally, in the third quarter of 2013, a state law was enacted that significantly reduced the carryforward period of certain state tax credits. As a result, a valuation allowance in the amount of approximately $3.3 million generated a discrete tax item for the quarter and three quarters ended September 30, 2013.
	Certain foreign losses generated are not more than likely to be realizable, and thus, no income tax benefit has been recognized on these losses. The Company’s foreign earnings attributable to the Asia Pacific operating segment will be permanently reinvested in such foreign jurisdictions and, therefore, no deferred tax liabilities for U.S. income taxes on undistributed earnings are recorded.

	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 foreign functional currency. The notional amount of the foreign exchange contracts as of September 29, 2014 and December 30, 2013 was approximately $30,379 and $47,000, respectively.

The fair value of available for sale securities was determined using quoted market prices for the securities on an active exchange.
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. The values were adjusted to reflect nonperformance risk of the counterparty and the Company, as necessary.
The fair value of the long-term debt was estimated based on discounting the debt over its life using current market rates for similar debt as of September 29, 2014 and December 30, 2013.
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 inputs.
As of September 29, 2014 and December 30, 2013, 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.

	(10) Significant Customers and Concentration of Credit Risk
	In the normal course of business, the Company extends credit to its customers, which are concentrated primarily in the computer, cellular phone, networking and communications, and aerospace and defense industries. Most are located outside the United States, with the exception of aerospace and defense industries. The Company performs ongoing credit evaluations of customers, does not require collateral and considers the credit risk profile of the entity from which the receivable is due in further evaluating collection risk.
	The Company’s customers include both OEM and EMS companies. The Company’s OEM customers often direct a significant portion of their purchases through EMS companies. While the Company’s customers include both OEM and EMS providers, the Company measures customer concentration based on OEM companies, as they are the ultimate end customers.
	For each of the quarters ended September 29, 2014 and September 30, 2013, one customer accounted for approximately 23% of the Company’s net sales. For the three quarters ended September 29, 2014 and September 30, 2013, one customer accounted for approximately 16% and 17%, respectively, of the Company’s net sales.

	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.
	At September 29, 2014 and December 30, 2013, the following financial assets and liabilities were measured at fair value on a recurring basis using the type of inputs shown:

	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 or probable 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 at September 29, 2014 and December 30, 2013. However, these amounts are not material to the consolidated condensed financial statements of the Company.
	Class Action Complaints related to Viasystems Acquisition
	Since the public announcement on September 22, 2014 of the execution of the Merger Agreement, Viasystems, TTM, Merger Sub, and the members of the Viasystems Board have been named as defendants in two putative class action complaints challenging the Merger. The first lawsuit, filed in the Circuit Court of St. Louis County, Missouri on September 30, 2014 (the Missouri Lawsuit), and the second lawsuit, filed in the Court of Chancery of the State of Delaware on October 13, 2014 (the Delaware Lawsuit and, together with the Missouri Lawsuit, the Lawsuits), generally allege that the Merger fails to properly value Viasystems, that the individual defendants breached their fiduciary duties in approving the Merger Agreement, and that those breaches were aided and abetted by TTM, Merger Sub, and Viasystems.
	The Delaware Lawsuit specifically alleges, among other allegations, that (1) the Viasystems Board breached its fiduciary duties by: (a) agreeing to the Merger for grossly inadequate consideration, (b) agreeing to lock up the Merger with deal protection devices that prevent other bidders from making a successful competing offer for Viasystems, and (c) participating in a transaction where the loyalties of the Viasystems Board and management are divided; (2) the voting agreements entered into between the Company and certain of Viasystems’ significant stockholders prevent Viasystems stockholders from providing a meaningful vote on the proposal to adopt the Merger; and (3) that those breaches of fiduciary duties were aided and abetted by TTM, Merger Sub, and Viasystems. Further, the Missouri Lawsuit specifically alleges, among other allegations, that (1) the proposed Merger is unfair and the consideration to be paid in connection with the Merger is inadequate; (2) the Viasystems Board and Viasystems’ management have a conflict of interest due to the cash pool bonus and change in control payments to be made to certain executive officers and key employees if the Merger is consummated; and (3) the Merger Agreement contains impermissible deal protection devices.
	The Lawsuits seek injunctive relief to enjoin the defendants from completing the Merger on the agreed-upon terms, rescinding, to the extent already implemented, the Merger Agreement or any of the terms therein, costs and disbursements and attorneys’ and experts’ fees and costs, as well as other equitable relief as the respective court deems proper. The Delaware Lawsuit also seeks: (1) in the event the Merger is consummated prior to the entry of the court’s final judgment, rescissory damages as an alternative to rescission, and (2) an accounting by all defendants to the plaintiff and other members of the class for all damages caused by the defendants and for all profits and any special benefits obtained as a result of their alleged breaches of their fiduciary duties. TTM believes the Lawsuits are without merit.
	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 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 Chinese environmental water waste law was issued in late 2012, but allows for an interim period in which plants subject to such law may install equipment that meets the new regulatory regime and come into full compliance with the new laws in 2014 and 2015, depending on the province of China in which such plant is located. The Company’s plants in China are not yet in full compliance with the newly adopted environmental regulations as updated in late 2012. The Company expects to come into compliance and 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, which includes capital expenditures estimated to be approximately $15, 000 through 2015, to address the regulatory changes in order to come into full compliance during the interim period.

	For the quarter ended September 30, 2013, potential shares of common stock, consisting of stock options to purchase approximately 954 shares of common stock at exercise prices ranging from $5.78 to $16.82 per share, 1,551 restricted stock units, and 118 performance-based restricted stock units 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.
	For the quarter and three quarters ended September 29, 2014, the effect of 27,970 shares of common stock, related to the Company’s convertible senior notes and warrants to purchase 28,020 shares of common stock were not included in the computation of dilutive earnings per share because the effect would be anti-dilutive under the treasury stock method. For the quarter and three quarters ended September 30, 2013, the effect of 10,963 shares of common stock, related to the Company’s convertible senior notes and warrants to purchase 10,963 shares of common stock were not included in the computation of dilutive earnings per share because the effect would be anti-dilutive under the treasury stock method.

	Performance-based Restricted Stock Units
	The Company maintains a long-term incentive program for executives that provides for the issuance of performance-based restricted stock units (PRUs), representing hypothetical shares of the Company’s common stock that may be issued. Under the PRU program, a target number of PRUs is awarded at the beginning of each three-year performance period. The number of shares of common stock released at the end of the performance period will range from zero to 2.4 times the target number depending on performance during the period. The performance metrics of the PRU program are based on (a) annual financial targets, which are based on revenue and EBITDA (earnings before interest, tax, depreciation, and amortization expense), each equally weighted, and (b) an overall modifier based on the Company’s total stockholder return (TSR) relative to the S&P SmallCap 600 for PRUs granted in 2012, and, for PRUs granted in 2013 and 2014, a group of peer companies selected by the Company’s compensation committee, over the three-year performance period.
	The Company records stock-based compensation expense for PRU awards granted based on management’s periodic assessment of the probability of the PRU awards vesting. PRUs activity for the three quarters ended September 29, 2014 was as follows:
			Shares

	The operating segments reported below are the Company’s segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company manages its worldwide operations based on two geographic operating segments: 1) Asia Pacific, which consists of five PCB fabrication plants and one drilling facility, and 2) North America, which consists of seven domestic PCB fabrication plants, including a facility that provides follow-on value-added services primarily for one of the PCB fabrication plants, and one backplane assembly plant in Shanghai, China, which is managed in conjunction with the Company’s U.S. operations. Each segment operates predominantly in the same industry with production facilities that produce similar customized products for its customers and use similar means of product distribution.
	The Company evaluates segment performance based on operating segment income, which is operating income before amortization of intangibles. Interest expense and interest income are not presented by segment since they are not included in the measure of segment profitability reviewed by the chief operating decision maker. All inter-segment transactions have been eliminated. Reportable segment assets exclude short-term investments, which are managed centrally.

	On May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. (ASU) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company at the beginning of fiscal year 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	In July 2013, the FASB issued an update that would require an unrecognized tax benefit, or a portion of an unrecognized benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. This update is effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The Company adopted the amendment on January 1, 2014, and its adoption did not have a material impact on its financial statements.
