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 (i.e., PCBs populated with electronic components), which serve as the foundation of sophisticated electronic products. The Company provides time-to-market and advanced technology products and offers a one-stop manufacturing solution to customers from engineering support to prototype development through final volume production. This one-stop manufacturing solution allows 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.
	Additionally, the Company serves a diversified customer base in various markets throughout the world, including manufacturers of networking/communications infrastructure products, touchscreen tablets and smartphones, as well as the 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 (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 Issued Accounting Standards
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2015-03, Interest-Imputation of Interest, which requires an entity to record debt issuance costs related to a note reported in the balance sheet as a direct deduction from the face amount of that note. The update is effective for annual periods ending after December 15, 2015. Early application is permitted. The standard requires the use of the retrospective transition method. The impact on the Company’s financial statements is not expected to be material.
	In August 2014, the FASB issued ASU 2014-15 Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern, which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern. The update is effective for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The impact on the Company’s financial statements of adopting ASU 2014-15 is not expected to be material.
	In May 2014, the FASB issued 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. ASU 2014-09 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. We are evaluating the effect that ASU 2014-09 will have on the Company’s consolidated financial statements and related disclosures. The Company has not yet selected a transition method, nor has the Company determined the effect of the standard on its ongoing financial reporting.

Convertible_Senior_Notes

Convertible Senior Notes	3 Months Ended

Convertible Senior Notes	(6) 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. 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.
	The maximum number of shares issuable upon conversion, including the effect of a fundamental change and subject to certain conversion adjustments, would be 32,425.
	Convertible Note Hedge and Warrant Transaction: In connection with the issuance of the convertible senior notes due 2020, the Company entered into a convertible note hedge and warrant transaction (Call Spread Transaction), with respect to the Company’s common stock. The convertible note hedge consists of the Company’s option to purchase up to 25,940 common stock shares at a price of $9.64 per share. The hedge expires on December 15, 2020 and can only be executed upon the conversion of the above mentioned convertible senior notes due 2020. Additionally, the Company sold warrants to purchase 25,940 shares of its common stock at a price of $14.26 per share. The warrants expire ratably from March 2021 through January 2022. The 2020 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.
	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. On May 15, 2015, the outstanding principal of $32,395 plus accrued interest is due and payable. 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.
	The maximum number of shares issuable upon conversion, including the effect of a fundamental change and subject to certain conversion adjustments, would be 2,587.

At March 30, 2015, the remaining weighted average amortization period for the unamortized senior convertible note discount and debt issuance costs was 5.7 years.
	For the quarters ended March 30, 2015 and March 31, 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.

Income Taxes	(7) Income Taxes
	The Company’s effective tax rate will generally differ from the U.S. federal statutory rate of 35% due to favorable tax rates associated with earnings from the Company’s operations in lower-tax jurisdictions in China, the apportioned state income tax rates, generation of other credits and deductions available to us, and certain non-deductible items. For both quarters ended March 30, 2015 and March 31, 2014, the Company’s effective tax rate was further impacted by a discrete tax benefit resulting from the retroactive approval of the high technology enterprise status for certain subsidiaries in China within the Company’s Asia Pacific operating segment.
	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 March 30, 2015 and December 29, 2014 was approximately $19,867 and $29,142, respectively.

Significant Customers and Concentration of Credit Risk	(10) Significant Customers and Concentration of Credit Risk
	In the normal course of business, the Company extends credit to its customers, which are concentrated primarily in the computer and networking, 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 quarters ended March 30, 2015 and March 31, 2014, one customer accounted for approximately 27% and 16%, respectively, of the Company’s net sales. There were no other customers that accounted for 10% or more of net sales for the quarters ended March 30, 2015 and March 31, 2014.

Fair Value Measures	(11) Fair Value Measures
	The Company measures at fair value its financial and non-financial assets by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability.
	The carrying amount and estimated fair value of the Company’s financial instruments at March 30, 2015 and December 29, 2014 were as follows:
		March 30, 2015				December 29, 2014
		Carrying		Fair		Carrying		Fair

	Convertible senior notes due 2020		198,880		274,200		197,042		241,875
	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 March 30, 2015 and December 29, 2014, 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 March 30, 2015 and December 29, 2014, 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.
	At March 30, 2015 and December 29, 2014, the following financial assets and liabilities were measured at fair value on a recurring basis using the type of inputs shown:
		March 30,		Fair Value Measurements Using:

	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 as of March 30, 2015 and December 29, 2014. However, these amounts are not material to the consolidated 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.
	On January 6, 2015, the parties to the Missouri Lawsuit entered into a Memorandum of Understanding (MOU) with respect to a proposed settlement that will terminate both Lawsuits upon entry of the final judgment. The parties are in the process of negotiating this settlement agreement. Pursuant to the MOU, the settlement agreement will provide for payment of attorneys’ fees and reimbursement of expenses, and releases of all claims and relief sought in both Lawsuits.
	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 the Chinese environmental waste water 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. 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 2015 capital expenditure costs expected for these plans are included in the Company’s capital expenditure projections.

	Earnings (loss) per share:
	Basic	$	0.04	$	(0.05	)
	Diluted	$	0.04	$	(0.05	)
	For the quarter ended March 30, 2015, performance-based restricted stock units (PRUs), restricted stock units (RSUs), and stock options to purchase 438 shares of common stock were not considered in calculating diluted earnings per share because the options’ exercise prices or the total assumed proceeds under the treasury stock method for PRUs, RSUs, or stock options was greater than the average market price of common shares during the applicable year and, therefore, the effect would be anti-dilutive.
	For the quarter ended March 31, 2014, potential shares of common stock, consisting of stock options to purchase approximately 597 shares of common stock at exercise prices ranging from $5.78 to $16.82 per share, 1,769 RSUs, and 229 PRUs were not included in the computation of diluted earnings per share because the Company incurred a net loss and, as a result, the impact would be anti-dilutive.
	Additionally, for both of the quarters ended March 30, 2015 and March 31, 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 conversion price of the convertible senior notes and 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.

	Total stock-based compensation expense after income taxes		$	1,518		$	1,598
	Performance-based Restricted Stock Units
	The Company maintains a long-term incentive program for executives that provides for the issuance of PRUs, representing hypothetical shares of the Company’s common stock that may be issued. Under the PRU program, a target number of PRUs is awarded at the beginning of each three-year performance period. The number of shares of common stock released at the end of the performance period will range from zero to 2.4 times the target number depending on performance during the period. The performance metrics of the PRU program are based on (a) annual financial targets, which are based on revenue and EBITDA (earnings before interest, tax, depreciation, and amortization expense), each equally weighted, and (b) an overall modifier based on the Company’s total stockholder return (TSR) relative to a group of peer companies selected by the Company’s compensation committee, over the three-year performance period.
	The Company records stock-based compensation expense for PRU awards granted based on management’s periodic assessment of the probability of the PRU awards vesting. For the quarter ended March 30, 2015, management determined that vesting of the PRU awards was probable. PRUs activity for the quarter ended March 30, 2015 was as follows:
			Shares			Weighted
						Average
						Fair Value
			(In thousands)
	Outstanding target shares at December 29, 2014			275		$	8.03

	Change in units due to annual financial target performance achievement			7			7.22
	Outstanding target shares at March 30, 2015			577		$	7.61
	The fair value for PRUs granted is calculated using a Monte Carlo simulation model, as the TSR modifier contains a market condition. For the quarters ended March 30, 2015 and March 31, 2014 the following assumptions were used in determining the fair value:
			March  30,			March  31,
			20151			20142

	-2	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 first year of the three-year performance period applicable to PRUs granted in 2014.
	Restricted Stock Units
	The Company granted 970 and 760 RSUs during the quarters ended March 30, 2015 and March 31, 2014, respectively. The RSUs granted have a weighted-average fair value per unit of $8.80 and $8.00 for the quarters ended March 30, 2015 and March 31, 2014, 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.

Segment Information	(15) Segment Information
	The operating segments reported below are the Company’s segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company manages its worldwide operations based on two geographic operating segments: 1) Asia Pacific, which consists of five PCB fabrication plants, 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 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.

	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2015-03, Interest-Imputation of Interest, which requires an entity to record debt issuance costs related to a note reported in the balance sheet as a direct deduction from the face amount of that note. The update is effective for annual periods ending after December 15, 2015. Early application is permitted. The standard requires the use of the retrospective transition method. The impact on the Company’s financial statements is not expected to be material.
	In August 2014, the FASB issued ASU 2014-15 Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern, which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern. The update is effective for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The impact on the Company’s financial statements of adopting ASU 2014-15 is not expected to be material.
	In May 2014, the FASB issued 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. ASU 2014-09 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. We are evaluating the effect that ASU 2014-09 will have on the Company’s consolidated financial statements and related disclosures. The Company has not yet selected a transition method, nor has the Company determined the effect of the standard on its ongoing financial reporting.
