Fair Value Measurements

Assets/Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company has investments in publicly-traded companies and mutual funds, both of which are valued using quoted market prices, representing Level 1 assets, and investments in interest rate cap derivative instruments, which are valued using analyses obtained from independent third party valuation specialists based on market observable inputs, representing Level 2 assets. The fair values of the Company's interest rate cap derivative instruments represent the estimated amounts the Company would receive to terminate the contracts. Refer to Note 5 for further discussion and information on the interest rate cap derivative instruments.

The Company has a payment obligation to the participants under its Nonqualified Deferred Compensation Plan (“DCP”). This liability is recorded at fair value based on the underlying value of certain hypothetical investments under the DCP as designated by each participant for their benefit. Since the value of the DCP obligation is based on market prices, the liability is classified within Level 1.

Assets and liabilities measured and recorded at fair value on a recurring basis consisted of the following at March 28, 2015:

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company remeasures the fair value of certain assets and liabilities upon the occurrence of certain events. Such assets are comprised of cost-method equity investments and long-lived assets, including property, plant and equipment, intangible assets and goodwill.

In the second quarter of fiscal 2014, the Company evaluated its MRI breast coils product line asset group, which is within its Breast Health segment, for impairment due to the Company’s expectation that it would be sold or disposed of significantly before the end of its previously estimated useful life. The undiscounted cash flows expected to be generated by this asset group over its estimated remaining useful life were not sufficient to recover its carrying value. The Company estimated the fair value of the asset group using market participant assumptions, which were based on underlying cash flow estimates, resulting in an impairment charge of $28.6 million. Pursuant to ASC 360, Property, Plant, and Equipment-Other, subtopic 10-35-28, the impairment charge was allocated to the long-lived assets, with $27.1 million to intangible assets and $1.5 million to property and equipment. The property and equipment charge was recorded to cost of product revenues and general and administrative expenses in the amounts of $0.3 million and $1.2 million, respectively. The Company believes this adjustment falls within Level 3 of the fair value hierarchy. This asset group was sold in the fourth quarter of fiscal 2014 (see Note 3).

In the first quarter of fiscal 2014, the Company recorded a $3.1 million impairment charge to record certain of its buildings at fair value related to the Hitec-Imaging organic photoconductor manufacturing line shutdown (see Note 3). The Company believes this adjustment falls within Level 3 of the fair value hierarchy.

The Company holds certain cost-method equity investments in non-publicly traded securities aggregating $4.4 million and $5.2 million at March 28, 2015 and September 27, 2014, respectively, which are included in other long-term assets on the Company’s Consolidated Balance Sheets. These investments are generally carried at cost, less any write-downs for other-than-temporary impairment charges. To determine the fair value of these investments, the Company uses all available financial information related to the entities, including information based on recent or pending third-party equity investments in these entities. In certain instances, a cost method investment’s fair value is not estimated as there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment and to do so would be impractical. In the three and six month periods ended March 29, 2014, the Company recorded other-than-temporary impairment charges of $3.0 million and $3.7 million, respectively, related to its cost-method equity investments.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments mainly consist of cash and cash equivalents, accounts receivable, marketable securities, cost-method equity investments, interest rate caps, insurance contracts, DCP liability, accounts payable and debt obligations. The carrying amounts of the Company’s cash equivalents, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these instruments. The Company’s marketable securities and interest rate caps are recorded at fair value. The carrying amount of the insurance contracts are recorded at the cash surrender value, as required by U.S. GAAP, which approximates fair value, and the related DCP liability is recorded at fair value. The Company believes the carrying amounts of its cost-method equity investments approximate fair value.

Amounts outstanding under the Company’s Credit Agreement of $1.69 billion aggregate principal as of March 28, 2015 are subject to variable rates of interest based on current market rates, and as such, the Company believes the carrying amount of these obligations approximates fair value. The Company’s Senior Notes had a fair value of approximately $1.04 billion as of March 28, 2015 based on their trading price, representing a Level 1 measurement. The fair value of the Company’s Convertible Notes is based on the trading prices of the respective notes and represents a Level 1 measurement. Refer to Note 4 for the carrying amounts of the various components of the Company’s debt.

The estimated fair values of the Company’s Convertible Notes at March 28, 2015 were as follows:



2010 Notes	$	652.3
2012 Notes	613.3
2013 Notes	430.2
	$	1,695.8
