Additionally, the Company entered into a $150,000 U.S. Asset-Based Lending Credit Agreement (U.S. ABL) and a $150,000 Asia Asset-Based Lending Credit agreement (Asia ABL) (collectively the ABL Revolving Loans). The Company drew $80,000 of the U.S. ABL at the closing of the acquisition of Viasystems. The Term Loan was issued at a discount at 96.5% and bears interest at a floating rate of LIBOR, with a 1.0% LIBOR floor, plus an applicable interest margin of 5.0%, or JP Morgan Chase Bank’s prime rate, with a 2% floor, plus a margin of 4%, at the Company’s option. At March 28, 2016, the weighted average interest rate on the outstanding borrowings under the Term Loan was 6.0%. There is no provision, other than an event of default, for the interest margin to increase. The Term Loan will mature on May 31, 2021. The Term Loan is secured by a significant amount of the assets of the Company and its domestic subsidiaries and a pledge of 65% of voting stock of the Company’s first tier foreign subsidiaries and is structurally senior to the Company’s convertible senior notes. See Convertible Senior Notes below. The U.S. ABL consists of three tranches comprised of a revolving credit facility of up to $150,000, a letter of credit facility of up to $75,000, and swingline loans of up to $30,000, provided that at no time may amounts outstanding under the tranches exceed in aggregate $150,000 or the applicable borrowing base, which is a percentage of the principal amount of Eligible Accounts, as defined in the U.S. ABL agreement. Borrowings under the U.S. ABL bear interest at either a floating rate of LIBOR plus a margin of 175 basis points or JP Morgan Chase Bank’s prime rate plus a margin of 75 basis points, at the Company’s option. At March 28, 2016, the weighted average interest rate on the outstanding borrowings under the U.S. ABL was 2.19%. Beginning in 2016, the applicable margin can vary based on the remaining availability of the facility, from 150 to 200 basis points for LIBOR-based loans or from 50 to 100 basis points for JP Morgan Chase Bank’s prime rate-based loans. Other than availability and an event of default, there are no other provisions for the interest margin to increase. The U.S. ABL will mature on May 31, 2020. Loans made under the U.S. ABL are secured first by all of the Company’s domestic cash, receivables and inventories as well as by a second position against a significant amount of the assets of the Company and its domestic subsidiaries and a pledge of 65% of voting stock of the Company’s first tier foreign subsidiaries and are structurally senior to the Company’s convertible senior notes. See Convertible Senior Notes below. At March 28, 2016, $80,000 of the U.S. ABL was outstanding and classified as short-term debt. The Company and its domestic subsidiaries have fully and unconditionally guaranteed the full and timely payment of all Term Loan and U.S. ABL related obligations. The Asia ABL consists of two tranches comprised of a revolving credit facility of up to $150,000 and a letter of credit facility of up to $100,000, provided that at no time may amounts outstanding under both tranches exceed in aggregate $150,000 or the applicable borrowing base, which is a percentage of the principal amount of Eligible Accounts, as defined in the Asia ABL agreement. Borrowings under the Asia ABL bear interest at a floating rate of LIBOR plus 175 basis points. There is no provision, other than an event of default, for the interest margin to increase. The Asia ABL will mature on May 22, 2020. Loans made under the Asia ABL are secured by a portion of the Company’s Asia Pacific cash and receivables and are structurally senior to the Company’s domestic obligations, including the convertible senior notes. See Convertible Senior Notes below. The Company’s Asia Pacific subsidiary and certain of its subsidiaries have fully and unconditionally guaranteed the full and timely payment of all Asia ABL related obligations. At March 28, 2016, none of the Asia ABL was outstanding. The Company is required to make scheduled payments of the outstanding Term Loan balance on a quarterly basis which began on October 1, 2015. Based on certain parameters defined in the Term Loan agreement, the Company may be required to make an additional principal payment on an annual basis. Any additional annual payments reduce future required quarterly scheduled payments. During the quarter ended March 28, 2016, the Company made debt principal payments totaling $76,482 representing normally scheduled principal payments as well as an additional prepayment of principal. Any other outstanding balances under the Term Loan are due at the maturity date of May 31, 2021. Borrowings under the Term Loan are subject to various financial and operating covenants including maintaining a maximum total leverage ratio. Under the occurrence of certain events, the U.S. ABL and the Asia ABL are subject to various financial and operational covenants, including maintaining minimum fixed charge coverage ratios. At March 28, 2016, the Company was in compliance with the covenants under the Term Loan, the U.S. ABL and the Asia ABL.

Income Taxes

Income Taxes	3 Months Ended
Income Taxes	Mar. 28, 2016
Income Taxes	(8) 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 such as China, the apportioned state income tax rates, generation of other credits and deductions available to the Company, changes in valuation allowances, and certain non-deductible items. During the quarter ended March 28, 2016, the Company’s effective tax rate was impacted by a net discrete benefit of $351 related to a tax holiday and accrued interest on existing uncertain tax positions. Additionally, no tax benefit was recorded on the losses incurred in the U.S. and certain foreign jurisdictions as a result of corresponding increases in the valuation allowances in these jurisdictions. The Company’s foreign earnings attributable to certain subsidiaries in China will be indefinitely reinvested in such foreign jurisdictions and, therefore, no deferred tax liabilities for U.S. income taxes on undistributed earnings are recorded. Certain entities in China operated under tax incentives effective through 2016. The tax incentives decreased Chinese taxes by $1,664, which increased both basic and diluted earnings per share by $0.02 for the quarter ended March 28, 2016. As of March 28, 2016, the Company had not finalized the determination of fair values allocated to various assets and liabilities, including, deferred taxes, tax uncertainties, and income taxes payable related to the acquisition of Viasystems. Any changes in the fair values of these liabilities assumed during the measurement period may result in material adjustments to goodwill.

Significant Customers and Concentration of Credit Risk	Mar. 28, 2016
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, networking and communications and aerospace and defense industries. Most customers to which the Company extends credit are located outside the United States, with the exception of certain customers in the aerospace and defense industries. The Company performs ongoing credit evaluations of customers, does not require collateral, and considers the credit risk profile of the entity from which the receivable is due in further evaluating collection risk. The Company’s customers include both OEMs and EMS companies. The Company’s OEM customers often direct a significant portion of their purchases through EMS companies. While the Company’s customers include both OEM and EMS providers, the Company measures customer concentration based on OEM companies, as they are the ultimate end customers. For the quarters ended March 28, 2016 and March 30, 2015, one customer accounted for approximately 10% and 27%, 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 28, 2016 and March 30, 2015.

Fair Value Measures

Fair Value Measures	3 Months Ended
Fair Value Measures	Mar. 28, 2016
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 28, 2016 and December 28, 2015 were as follows: March 28, 2016 December 28, 2015 Carrying Amount Fair Value Carrying Amount Fair Value (In thousands) Term and Revolving Loans $ 898,008 $ 907,586 $ 970,764 $ 935,000 Convertible senior notes due 2020 202,178 220,350 200,022 230,950 Capital lease 2,038 2,038 — — 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 March 28, 2016 and December 28, 2015, which are considered Level 1 and Level 2 inputs. The fair value of the convertible senior notes was estimated based on quoted market prices of the securities on an active exchange, which are considered Level 1 and Level 2 inputs. As of March 28, 2016 and December 28, 2015, the Company’s other financial instruments also included cash and cash equivalents, accounts receivable, accounts payable and equipment payables. Due to short-term maturities, the carrying amount of these instruments approximates fair value. Our cash and cash equivalents at March 28, 2016 consisted of $41,640 held in the U.S., with the remaining $142,038 held by foreign subsidiaries. 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 for 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. For the quarter ended March 28, 2016, the following assets were measured at fair value on a nonrecurring basis using the type of inputs shown: Fair Value Measurements Using: March 28, 2016 Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Losses for the Quarter Ended March 28, 2016 (In thousands) Assets held for sale $ 155 $ — $ 155 $ — $ 1,393 Long-lived assets held and use 2,254 — — 2,254 1,953 $ 3,346 There was no impairment of long-lived assets recognized in the quarter ended March 30, 2015. The fair values of assets held for sale were primarily determined using appraisals and comparable prices of similar assets, which are considered to be Level 2 inputs. Additionally, the Company has capitalized software costs in accordance with U.S. GAAP. During the first quarter ended March 28, 2016, the Company determined that certain capitalized costs no longer had benefit primarily as a result of the Viasystems acquisition. Because the primary determination of fair value was based on management’s assumptions and estimates of capitalized costs to dispose, the resulting fair value is considered a Level 3 input.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended
Commitments and Contingencies	Mar. 28, 2016
Commitments and Contingencies	(12) 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 March 28, 2016 and December 28, 2015. 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 and chemical use reporting. The Company believes that its facilities in the United States, Canada and Mexico comply in all material respects with applicable environmental laws and regulations. In China, governmental authorities have adopted new rules and regulations governing environmental issues. An update to the Chinese environmental waste water law was issued in late 2012, allowing for an interim period in which plants subject to such law may install equipment that meets the new regulatory regime. Some of the Company’s plants in China are not yet in full compliance with the updated environmental regulations. The Company believes it has developed plans acceptable to the Chinese government and is in the process of implementing these plans. The Company does not anticipate any immediate risk of government fines or temporary closure of its Chinese plants. The Company has established and enacted an investment plan related to the efforts to come into full compliance with the new regulations. The 2016 capital expenditure costs expected for these plans are included in the Company’s capital expenditure projections.

For the quarter ended March 30, 2015, PRUs, RSUs, and stock options to purchase 438 of 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. Additionally, for the quarter ended March 28, 2016, the effect of shares of common stock related to the Company’s convertible senior notes, based on the if-converted method, were not included in the computation of dilutive 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 ended March 30, 2015, the effect of shares of common stock related to the Company’s convertible senior notes, based on the treasury stock method, were not included in the computation of dilutive earnings per share because the conversion price of the convertible senior notes were greater than the average market price of common shares during the quarter, and therefore, the effect would be anti-dilutive. Outstanding warrants for the quarters ended March 28, 2016 and March 30, 2015, to purchase common stock of 25,940 and 27,970, respectively, were not included in the computation of dilutive earnings per share because the strike price of the warrants to purchase the Company’s common stock were greater than the average market price of common shares during the applicable quarter, and therefore, the effect would be anti-dilutive.

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 28, 2016, management determined that vesting of the PRU awards was probable. PRUs activity for the quarter ended March 28, 2016 was as follows: Shares Weighted Average Fair Value (In thousands) Outstanding target shares at December 28, 2015 301 $ 8.58 Granted 347 6.46 Change in units due to annual financial target performance achievement — — Outstanding target shares at March 28, 2016 648 $ 7.45 The fair value for PRUs granted is calculated using a Monte Carlo simulation model, as the TSR modifier contains a market condition.

Restricted Stock Units The Company granted 1,683 and 970 RSUs during the quarters ended March 28, 2016 and March 30, 2015, respectively. The RSUs granted have a weighted-average fair value per unit of $6.75 and $8.80 for the quarters ended March 28, 2016 and March 30, 2015, 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 The Company did not grant any stock option awards during the quarters ended March 28, 2016 and March 30, 2015.

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. As a result of the acquisition of Viasystems and the new business structure implemented in the quarter ended March 28, 2016, the Company has reassessed its reportable operating segments and determined that it has two reportable operating segments: PCB and E-M Solutions. This determination was made based on the criteria of earning revenues and incurring expenses, the Company’s organizational structure which has segment managers who report to the chief operating decision maker and discrete financial information, and the aggregation of similar operating segments into reportable 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. All prior-period amounts have been adjusted retrospectively to reflect our reportable segment changes. The Company, including the chief operating decision maker, 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.
