	(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 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 on January 1, 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.

	(3) 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 year ended December 30, 2013 and reclassified such assets to assets held for sale, which were included in other current assets in the December 30, 2013 consolidated balance sheet.
	In the quarter ended June 30, 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 as the carrying value of the assets was greater than the market value at the date of disposal.

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 5. The Company has fully and unconditionally guaranteed the full and timely payment of all Credit Agreement related obligations of its Asia Pacific operating segment.

At June 30, 2014, the remaining amortization period for the unamortized debt issuance costs was 2.0 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 $151 and $95 for the quarters ended June 30, 2014 and July 1, 2013, respectively, and $284 and $191 for the two quarters ended June 30, 2014 and July 1, 2013, respectively. As of June 30, 2014, the outstanding amount of the Term Loan under the Credit Agreement was $321,900, of which $96,200 is due for repayment through March 2015 and is included as short-term debt, with the remaining $225,700 included as long-term debt. None of the Revolver was outstanding under the Credit Agreement as of June 30, 2014. Available borrowing capacity under the Revolving Loan was $90,000 at June 30, 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 (PRC). Under this arrangement, the lender has made available to the Company approximately $46,600 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 June 30, 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 June 30, 2014, letters of credit in the amount of $46,183 were outstanding under this Credit Agreement. The Company has other standby letters of credit outstanding in the amount of $3,894, as well other unused letter of credit facilities in the amount of $24,100. The outstanding standby letters of credit and unused letter of credit facilities expire between December 31, 2014 and February 28, 2015.

	(5) 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.

	The accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion require the debt and equity components to be separately accounted for in a manner that reflects our nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to the Company’s at the time of issuance. The difference between the debt recorded at inception and its principal amount is to be accreted to principal through interest expense through the estimated life of the note.

The debt issuance costs and debt discount are being amortized to interest expense over the term of the convertible senior notes using the effective interest rate method. At June 30, 2014, the remaining weighted average amortization period for the unamortized senior convertible note discount and debt issuance costs was 6.3 years.

For the quarter and two quarters ended June 30, 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 two quarters ended July 1, 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%.

	(6) Income Taxes
	The Company’s effective tax rate was (19.6)% and 40.5% for the quarters ended June 30, 2014 and July 1, 2013, respectively, and 16.3% and 33.3% for the two quarters ended June 30, 2014 and July 1, 2013, respectively. 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.
	During the quarter ended June 30, 2014, the Company’s effective tax rate was impacted by losses incurred in certain foreign jurisdictions for which no tax benefit was recorded as a result of full valuation allowances. During the two quarters ended June 30, 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 Chinese subsidiaries within the Company’s Asia Pacific operating segment.
	The Company’s effective tax rate for the quarter and two quarters ended July 1, 2013 was impacted by the gain on sale of assets in one of the Company’s foreign operations and an increase in income earned in higher tax jurisdictions, offset by the impact of discrete tax benefits from the extension of federal research and development credit laws, and from the approval of research and development deduction in China.
	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 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 June 30, 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 June 30, 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.

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 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 quarter ended June 30, 2014 no one customer accounted for 10% or more of the Company’s net sales. For the quarter ended July 1, 2013 one customer accounted for approximately 14% of the Company’s net sales. For the two quarters ended June 30, 2014 and July 1, 2013 one customer accounted for approximately 12% and 14%, respectively, of the Company’s net sales.

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 June 30, 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 June 30, 2014 and December 30, 2013. However, these amounts are not material to the consolidated condensed financial statements of the Company.
	Environmental Matters
	The process to manufacture PCBs requires adherence to city, county, state, federal and foreign environmental regulations regarding the storage, use, handling and disposal of chemicals, solid wastes and other hazardous materials as well as compliance with air quality standards. 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 are taking various steps to tighten the rules and regulations governing environmental issues. An update to Chinese environmental law was issued in late 2012, but allows for an interim period in which foreign entities may adjust to the new regulatory regime and come into full compliance with the new laws. The Company’s plants in China are not yet in full compliance with the current 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 $10,000 for 2014, to address the regulatory changes in order to come into full compliance during the interim period.

	For the quarter and two quarters ended July 1, 2013, performance-based stock units, restricted stock units and stock options to purchase 2,162 and 2,335 shares of common stock, respectively, were not considered in calculating diluted earnings per share because the options’ exercise prices or the total expected proceeds under the treasury stock method for performance-based stock units, restricted stock units or stock options was greater than the average market price of common shares during the period and, therefore, the effect would be anti-dilutive.

	For the quarters and two quarters ended June 30, 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.

	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. For the quarter and two quarters ended June 30, 2014, management determined that vesting of the PRU awards was probable. PRUs activity for the two quarters ended June 30, 2014 was as follows:

	The fair value for PRUs granted is calculated using a Monte Carlo simulation model, as the TSR modifier contains a market condition. For the two quarters ended June 30, 2014 and July 1, 2013, the following assumptions were used in determining the fair value:

The units granted have a weighted-average fair value per unit of $7.96 and $6.96 for the quarters ended June 30, 2014 and July 1, 2013, respectively, and $8.00 and $8.17 for the two quarters ended June 30, 2014 and July 1, 2013, respectively.

	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 on January 1, 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.
