Fair Value Measurements

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents, derivatives, marketable securities and accounts receivable. The Company believes it had no significant concentrations of credit risk as of June 28, 2015.

The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during the six months ended June 28, 2015. The Company’s financial assets and liabilities carried at fair value are primarily comprised of marketable securities, derivative contracts used to hedge the Company’s currency risk, and acquisition-related contingent consideration. The Company has not elected to measure any additional financial instruments or other items at fair value.

Valuation Hierarchy: The following summarizes the three levels of inputs required to measure fair value. For Level 1 inputs, the Company utilizes quoted market prices as these instruments have active markets. For Level 2 inputs, the Company utilizes quoted market prices in markets that are not active, broker or dealer quotations, or utilizes alternative pricing sources with reasonable levels of price transparency. For Level 3 inputs, the Company utilizes unobservable inputs based on the best information available, including estimates by management primarily based on information provided by third-party fund managers, independent brokerage firms and insurance companies. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible.

The following tables show the assets and liabilities carried at fair value measured on a recurring basis as of June 28, 2015 and December 28, 2014 classified in one of the three classifications described above:

Level 1 and Level 2 Valuation Techniques: The Company’s Level 1 and Level 2 assets and liabilities are comprised of investments in equity and fixed-income securities as well as derivative contracts. For financial assets and liabilities that utilize Level 1 and Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including common stock price quotes, foreign exchange forward prices and bank price quotes. Below is a summary of valuation techniques for Level 1 and Level 2 financial assets and liabilities.

Marketable securities: Include equity and fixed-income securities measured at fair value using the quoted market prices in active markets at the reporting date.

Foreign exchange derivative assets and liabilities: Include foreign exchange derivative contracts that are valued using quoted forward foreign exchange prices at the reporting date. The Company’s foreign exchange derivative contracts are subject to master netting arrangements that allow the Company and its counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled under these arrangements have been presented in the Company's consolidated balance sheet on a net basis and are recorded in other assets. As of both June 28, 2015 and December 28, 2014, none of the master netting arrangements involved collateral.

Level 3 Valuation Techniques: The Company’s Level 3 liabilities are comprised of contingent consideration related to acquisitions. For liabilities that utilize Level 3 inputs, the Company uses significant unobservable inputs. Below is a summary of valuation techniques for Level 3 liabilities.

Contingent consideration: The Company has classified its net liabilities for contingent consideration relating to its acquisitions within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which included probability weighted cash flows. A description of the significant acquisitions is included within Note 2 to the Company's audited consolidated financial statements filed with the 2014 Form 10-K. Contingent consideration is measured at fair value at the acquisition date, based on the probability that revenue thresholds or product development milestones will be achieved during the earnout period. Increases or decreases in the fair value of contingent consideration liabilities primarily result from changes in the estimated probabilities of achieving revenue thresholds or product development milestones during the earnout period. The Company may have to pay contingent consideration, related to acquisitions with open contingency periods, of up to $32.5 million as of June 28, 2015. As of June 28, 2015, the Company had recorded contingent consideration obligations, which were assumed as part of the Perten acquisition, with an estimated fair value of $0.5 million. The earnout period for acquisitions with open contingency periods does not exceed three years from the respective acquisition date, and the remaining weighted average earnout period at June 28, 2015 was four months.

A reconciliation of the beginning and ending Level 3 net liabilities for contingent consideration is as follows:



	Three Months Ended						Six Months Ended
	June 28, 2015			June 29, 2014			June 28, 2015			June 29, 2014
	(In thousands)
Balance at beginning of period	$	(81	)	$	(4,981	)	$	(91	)	$	(4,926	)
Additions	(475		)	—			(475		)	—
Amounts paid and foreign currency translation	—			(72		)	10			(72		)
Change in fair value (included within selling, general and administrative expenses)	81			1,623			81			1,568
Balance at end of period	$	(475	)	$	(3,430	)	$	(475	)	$	(3,430	)

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturities of these assets and liabilities. If measured at fair value, cash and cash equivalents would be classified as Level 1.

The Company’s senior unsecured revolving credit facility, which provides for $700.0 million of revolving loans, had amounts outstanding, excluding letters of credit, of $451.0 million and $516.0 million as of June 28, 2015 and December 28, 2014, respectively. The interest rate on the Company’s senior unsecured revolving credit facility is reset at least monthly to correspond to variable rates that reflect currently available terms and conditions for similar debt. The Company had no change in credit standing during the first six months of fiscal year 2015. Consequently, the carrying value of the current year and prior year credit facilities approximate fair value and would be classified as Level 2.

The Company's 2021 Notes, with a face value of $500.0 million, had an aggregate carrying value of $497.8 million, net of $2.2 million of unamortized original issue discount, and a fair value of $526.7 million as of June 28, 2015. The 2021 Notes had an aggregate carrying value of $497.7 million, net of $2.3 million of unamortized original issue discount, and a fair value of $542.7 million as of December 28, 2014. The fair value of the 2021 Notes is estimated using market quotes from brokers and is based on current rates offered for similar debt.

The Company's financing lease obligations had an aggregate carrying value of $38.7 million and $39.3 million as of June 28, 2015 and December 28, 2014, respectively. The carrying values of the Company's financing lease obligations approximated their fair value as there has been minimal change in the Company's incremental borrowing rate. As of June 28, 2015, the 2021 Notes and financing lease obligations were classified as Level 2.

As of June 28, 2015, there has not been any significant impact to the fair value of the Company’s derivative liabilities due to credit risk. Similarly, there has not been any significant adverse impact to the Company’s derivative assets based on the evaluation of its counterparties’ credit risks.
