Summary of Significant Accounting Policies (Policies)

12 Months Ended

Sep. 24, 2016

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year ends on the last Saturday in September. Fiscal 2016, 2015 and 2014 ended on September 24, 2016, September 26, 2015 and September 27, 2014, respectively.

Management's Estimates

Management’s Estimates and Uncertainties

The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions by management affect the Company’s revenue recognition for multiple element arrangements, allowance for doubtful accounts, the net realizable value of inventory, estimated fair value of cost-method equity investments, valuations, purchase price allocations and contingent consideration related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of intangible assets and goodwill, amortization methods and periods, warranty reserves, certain accrued expenses, restructuring and other related charges, stock-based compensation, contingent liabilities, tax reserves, deferred tax rates and recoverability of the Company’s net deferred tax assets and related valuation allowances.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.

The Company is subject to a number of risks similar to those of other companies of similar size in its industry, including dependence on third-party reimbursements to support the markets of the Company’s products, early stage of development of certain products, rapid technological changes, recoverability of long-lived assets (including intangible assets and goodwill), competition, stability of world financial markets, ability to obtain regulatory approvals, changes in the regulatory environment, limited number of suppliers, customer concentration, integration of acquisitions, substantial indebtedness, government regulations, management of international activities, protection of proprietary rights, patent and other litigation, dependence on contract manufacturers and dependence on key individuals.

Cash Equivalents

Cash equivalents are highly liquid investments with insignificant interest rate risk and maturities of three months or less at the time of acquisition.

Marketable Securities

The Company’s marketable securities as of September 24, 2016 are comprised of solely of equity securities and as of September 26, 2015 also included mutual funds. The equity securities are investments in the common stock of publicly traded companies, and the mutual funds were used to fund a portion of the Company's deferred compensation plan. The equity securities are classified as available-for-sale and are recorded at fair value with the unrealized gains or losses, net of tax, within accumulated other comprehensive income (loss), which is a component of stockholders’ equity. The mutual funds were classified as trading and recorded at fair value with unrealized gains and losses recorded in other income (expense), net in the Consolidated Statements of Income.

The Company periodically reviews its marketable equity securities classified as available-for-sale for other-than-temporary declines in fair value below carrying value, or whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. The determination that a decline is other-than-temporary is, in part, subjective and influenced by many factors. When assessing marketable equity securities for other-than-temporary declines in fair value, the Company considers factors including: the significance of the decline in value compared to the carrying value; the underlying factors contributing to a decline in the price of the security; how long the market value of the investment has been less than its carrying value; any market conditions that impact liquidity; the views of external investment analysts; the financial condition and near-term prospects of the investee; any news or financial information that has been released specific to the investee; and the outlook for the overall industry in which the investee operates. In the fourth quarters of fiscal 2016 and 2015, the Company concluded that the decline in fair value of one of its marketable securities was other-than-temporary based on the length of time the security's market value was significantly below its carrying value and recorded impairment charges of $1.1 million and $7.8 million, respectively.

The following reconciles cost basis to fair market value.



	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Other Than Temporary Impairment			Fair Value
As of September 24, 2016	$	2.4	$	—	$	(0.3	)	$	(1.1	)	$	1.0
As of September 26, 2015	$	16.1	$	7.2	$	(0.3	)	$	(7.8	)	$	15.2
As of September 27, 2014	$	15.5	$	10.2	$	(1.3	)	$	—		$	24.4

In the first quarter of fiscal 2016, the Company sold all of its shares in one of its marketable securities and recorded a realized gain of $25.1 million in Other income (expense), net.

Concentrations of Credit Risk

Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents, cost-method equity investments, and trade accounts receivable. The Company invests its cash and cash equivalents with high credit quality financial institutions.

The Company’s customers are principally located in the United States, Europe and Asia. The Company performs ongoing credit evaluations of the financial condition of its customers and generally does not require collateral. Although the Company is directly affected by the overall financial condition of the healthcare industry, as well as global economic conditions, management does not believe significant credit risk exists as of September 24, 2016. The Company generally has not experienced any material losses related to receivables from individual customers or groups of customers in the healthcare industry. The Company maintains an allowance for doubtful accounts based on accounts past due and historical collection experience.

There were no customers with balances greater than 10% of accounts receivable as of September 24, 2016 and September 26, 2015, or any customers that represented greater than 10% of consolidated revenues for fiscal years 2016, 2015 and 2014 (see Note 13).

Supplemental Cash Flow Statement Information



	Years ended
	September 24, 2016		September 26, 2015		September 27, 2014
Cash paid during the period for income taxes	$	184.8	$	168.7	$	231.8
Cash paid during the period for interest	$	104.0	$	143.0	$	155.7

Inventories

Inventories are valued at the lower of cost or market on a first in, first out basis. Work-in-process and finished goods inventories consist of materials, labor and manufacturing overhead. The valuation of inventory requires management to estimate excess and obsolete inventory. The Company employs a variety of methodologies to determine the net realizable value of its inventory. Provisions for excess and obsolete inventory are primarily based on management’s estimates of forecasted sales, usage levels and expiration dates, as applicable for disposable products. A significant change in the timing or level of demand for the Company’s products compared to forecasted amounts may result in recording additional charges for excess and obsolete inventory in the future. The Company records charges for excess and obsolete inventory within cost of product revenues.

Inventories consisted of the following:



	September 24, 2016		September 26, 2015
Raw materials	$	96.4	$	98.3
Work-in-process	51.7		58.7
Finished goods	126.6		126.1
	$	274.7	$	283.1

Property, Plant and Equipment

Property, plant and equipment is recorded at cost less allowances for depreciation. The straight-line method of depreciation is used for all property and equipment.

Property, plant and equipment consisted of the following:



	September 24, 2016			September 26, 2015
Equipment and software	$	381.9		$	365.9
Equipment under customer usage agreements	334.6			305.7
Buildings and improvements	186.1			182.1
Leasehold improvements	65.6			59.2
Land	51.9			51.4
Furniture and fixtures	18.4			17.3
	1,038.5			981.6
Less - accumulated depreciation and amortization	(578.3		)	(524.5		)
	$	460.2		$	457.1

Property, plant and equipment are depreciated over the following estimated useful lives:



Asset Classification		Estimated Useful Life
Building and improvements		35–40 years
Equipment and software		3–10 years
Equipment under customer usage agreements		3–8 years
Furniture and fixtures		5–7 years
Leasehold improvements		Shorter of the Original Term of Lease or Estimated Useful Life

Equipment under customer usage agreements primarily consists of diagnostic instrumentation and imaging equipment located at customer sites but owned by the Company. Generally, the customer has the right to use the equipment for a period of time provided they meet certain agreed to conditions. The Company recovers the cost of providing the equipment from the sale of disposables. The depreciation costs associated with equipment under customer usage agreements are charged to cost of product revenues over the estimated useful life of the equipment. The costs to maintain the equipment in the field are charged to cost of product revenue as incurred.

Long-Lived Assets

The Company reviews its long-lived assets, which includes property, plant and equipment and identifiable intangible assets (see below for discussion of intangible assets), for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in accordance with ASC 360-10-35-15, Property, Plant and Equipment—Impairment or Disposal of Long-Lived Assets (ASC 360). Recoverability of these assets is evaluated by comparing the carrying value of the assets to the undiscounted cash flows estimated to be generated by those assets over their remaining economic life. If the undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are considered impaired. The impairment loss is measured by comparing the fair value of the assets to their carrying value. Fair value is determined by either a quoted market price, if any, or a value determined by a discounted cash flow technique.

In the second quarter of fiscal 2014, the Company evaluated its MRI breast coils product line asset group, which was 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. At this time, 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 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. The Company completed the sale of this product line 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 shutdown of its Hitec Imaging organic photoconductor manufacturing line (see Note 3).

Business Combinations and Acquisition of Intangible Assets

The Company records tangible and intangible assets acquired in business combinations under the purchase method of accounting. The Company accounts for acquisitions in accordance with ASC 805, Business Combinations (ASC 805). Amounts paid for each acquisition are allocated to the assets acquired and liabilities assumed based on their fair values at the dates of acquisition. The Company allocates the purchase price in excess of the fair value of the net tangible assets acquired to identifiable intangible assets, including purchased research and development, based on detailed valuations that use certain information and assumptions provided by management. The Company allocates any excess purchase price over the fair value of the net tangible and intangible assets acquired to goodwill. The use of alternative valuation assumptions, including estimated cash flows and discount rates, and alternative useful life assumptions could result in different purchase price allocations and intangible asset amortization expense in current and future periods.

The Company uses the income approach to determine the fair value of developed technology and in-process research and development ("IPR&D") acquired in a business combination. This approach determines fair value by estimating the after-tax cash flows attributable to the respective asset over its useful life and then discounting these after-tax cash flows back to a present value. The Company bases its revenue assumptions on estimates of relevant market sizes, expected market growth rates, expected trends in technology and expected product introductions by competitors. Developed technology represents patented and unpatented technology and know-how. Regarding the value of the in-process projects, the Company considers, among other factors, the in-process projects’ stage of completion, the complexity of the work completed as of the acquisition date, the projected costs to complete, the contribution of core technologies and other acquired assets, the expected introduction date and the estimated useful life of the technology. The Company believes that the estimated developed technology and IPR&D amounts represent the fair value at the date of acquisition and do not exceed the amount a third-party would pay for the assets.

The Company also uses the income approach, as described above, to determine the estimated fair value of certain other identifiable intangible assets including customer relationships, trade names and business licenses. Customer relationships represent established relationships with customers, which provide a ready channel for the sale of additional products and services. Trade names represent acquired company and product names.

Intangible Assets and Goodwill

Intangible Assets

Intangible assets are initially recorded at fair value and stated net of accumulated amortization and impairments. The Company amortizes its intangible assets that have finite lives using either the straight-line method, or if reliably determinable, based on the pattern in which the economic benefit of the asset is expected to be utilized. Amortization is recorded over the estimated useful lives ranging from 2 to 30 years. The Company evaluates the realizability of its definite lived intangible assets whenever events or changes in circumstances or business conditions indicate that the carrying value of these assets may not be recoverable based on expectations of future undiscounted cash flows for each asset group. If the carrying value of an asset or asset group exceeds its undiscounted cash flows, the Company estimates the fair value of the assets, generally utilizing a discounted cash flow analysis based on the present value of estimated future cash flows to be generated by the assets using a risk-adjusted discount rate. To estimate the fair value of the assets, the Company uses market participant assumptions pursuant to ASC 820, Fair Value Measurements.

Indefinite lived intangible assets, such as IPR&D assets, are required to be tested for impairment annually, or more frequently if indicators of impairment are present. The Company’s annual impairment test date is as of the first day of its fourth quarter.

During the fourth quarter of fiscal 2014, the Company recorded impairment charges of $5.1 million for a reduction in fair value of its remaining IPR&D assets. The reduction in fair value was primarily due to lower revenue projections of the respective products compared to those estimated at the time of the Gen-Probe acquisition.

During the second quarter of fiscal 2014, the Company recorded impairment charges of $26.6 million and $0.5 million to developed technology and trade names, respectively, related to its MRI breast coils product line discussed above. In addition, the Company periodically re-evaluates the lives of its definite-lived intangible assets, and in the second quarter of fiscal 2014 shortened the life of certain corporate trade names, which were phased out.

Intangible assets consisted of the following:



	September 24, 2016				September 26, 2015
Description	Gross Carrying Value		Accumulated Amortization		Gross Carrying Value		Accumulated Amortization
Developed technology	$	3,983.7	$	1,991.6	$	3,979.1	$	1,698.5
In-process research and development	3.7		—		3.7		—
Customer relationships and contracts	1,098.9		546.2		1,101.1		467.5
Trade names	236.2		141.6		236.4		131.5
Business licenses	2.4		2.1		2.5		2.1
	$	5,324.9	$	2,681.5	$	5,322.8	$	2,299.6

In the third quarter of fiscal 2016, the Company accelerated the amortization of the Cystic Fibrosis developed technology asset of $6.2 million as a result of discontinuing this product line.

In the second quarter of fiscal 2016, the Company acquired certain intellectual property for $4.8 million, which was recorded in developed technology.

Amortization expense related to developed technology is classified as a component of cost of product revenues—amortization of intangible assets. Amortization expense related to customer relationships and contracts, trade names, and business licenses is classified as a component of amortization of intangible assets within operating expenses.

The estimated amortization expense at September 24, 2016 for each of the five succeeding fiscal years was as follows:



Fiscal 2017	$	365.8
Fiscal 2018	$	355.0
Fiscal 2019	$	343.1
Fiscal 2020	$	331.4
Fiscal 2021	$	312.0

Goodwill

In accordance with ASC 350, Intangibles—Goodwill and Other (ASC 350), the Company tests goodwill for impairment at the reporting unit level on an annual basis and between annual tests if events and circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. Events that could indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate, operational performance of the business or key personnel, and an adverse action or assessment by a regulator.

In performing the impairment test, the Company utilizes the two-step approach prescribed under ASC 350. The first step requires a comparison of the carrying value of each reporting unit to its estimated fair value. To estimate the fair value of its reporting units for Step 1, the Company primarily utilizes the income approach. The income approach is based on a DCF analysis and calculates the fair value by estimating the after-tax cash flows attributable to a reporting unit and then discounting the after-tax cash flows to a present value using a risk-adjusted discount rate. Assumptions used in the DCF require significant judgment, including judgment about appropriate discount rates and terminal values, growth rates, and the amount and timing of expected future cash flows. The forecasted cash flows are based on the Company’s most recent budget and strategic plan and for years beyond this period, the Company’s estimates are based on assumed growth rates expected as of the measurement date. The Company believes its assumptions are consistent with the plans and estimates used to manage the underlying businesses. The discount rates used are intended to reflect the risks inherent in future cash flow projections and are based on estimates of the weighted-average cost of capital (“WACC”) of market participants relative to each respective reporting unit. The market approach considers comparable market data based on multiples of revenue or earnings before interest, taxes, depreciation and amortization (“EBITDA”) and is primarily used as a corroborative analysis to the results of the DCF analysis. The Company believes its assumptions used to determine the fair value of its reporting units are reasonable. If different assumptions were used, particularly with respect to forecasted cash flows, terminal values, WACCs, or market multiples, different estimates of fair value may result and there could be the potential that an impairment charge could result. Actual operating results and the related cash flows of the reporting units could differ from the estimated operating results and related cash flows.

If the carrying value of a reporting unit exceeds its estimated fair value, the Company is required to perform the second step of the goodwill impairment test to measure the amount of impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of a reporting unit’s goodwill to its carrying value. The implied fair value of goodwill is derived by performing a hypothetical purchase price allocation for each reporting unit as of the measurement date and allocating the reporting unit’s estimated fair value to its assets and liabilities. The residual amount from performing this allocation represents the implied fair value of goodwill. To the extent this amount is below the carrying value of goodwill, an impairment charge is recorded.

The Company conducted its fiscal 2016 impairment test on the first day of the fourth quarter, and as noted above used DCF and market approaches to estimate the fair value of its reporting units as of June 26, 2016, and ultimately used the fair value determined by the DCF approach in making its impairment test conclusions. The Company believes it used reasonable estimates and assumptions about future revenue, cost projections, cash flows, market multiples and discount rates as of the measurement date. As a result of completing Step 1, all of the Company's reporting units had fair values exceeding their carrying values, and as such, Step 2 of the impairment test was not required. For illustrative purposes, had the fair value of each of the reporting units that passed Step 1 been lower than 10%, all of the reporting units would still have passed Step 1 of the goodwill impairment test.

At September 24, 2016, the Company believes that each reporting unit, with goodwill aggregating $2.80 billion, was not at risk of failing Step 1 of the goodwill impairment test based on the current forecasts.

The Company conducted its fiscal 2015 and 2014 impairment tests on the first day of the respective year's fourth quarter, and as noted above used DCF and market approaches to estimate the fair value of its reporting units as of June 28, 2015 and June 29, 2014, respectively, and ultimately used the fair value determined by the DCF approach in making its impairment test conclusions. The Company believes it used reasonable estimates and assumptions about future revenue, cost projections, cash flows, market multiples and discount rates as of the measurement date. As a result of completing Step 1, all of the Company's reporting units had fair values exceeding their carrying values, and as such, Step 2 of the impairment test was not required.

A rollforward of goodwill activity by reportable segment from September 26, 2015 to September 24, 2016 is as follows:



	Diagnostics			Breast Health		GYN Surgical			Skeletal Health		Total
Balance at September 26, 2015	$	1,152.3		$	631.8	$	1,016.0		$	8.1	$	2,808.2
Tax adjustments	(1.3		)	—		—			—		(1.3		)
Foreign currency and other	(2.8		)	—		(1.0		)	—		(3.8		)
Balance at September 24, 2016	$	1,148.2		$	631.8	$	1,015.0		$	8.1	$	2,803.1

Other Assets

Other assets consisted of the following:



	September 24, 2016		September 26, 2015
Other Assets
Life insurance contracts	$	36.0	$	27.5
Manufacturing access fees	9.6		11.6
Derivative assets	0.4		6.2
Mutual funds	—		5.6
Marketable securities	1.0		15.2
Cost-method equity investments	3.5		4.2
Deferred tax assets	9.3		—
Other	23.9		17.9
	$	83.7	$	88.2

Life insurance contracts were purchased in connection with the Company’s Nonqualified Deferred Compensation Plan (“DCP”) and are recorded at their cash surrender value (see Note 9 for further discussion). The manufacturing access fees are related to a manufacturing supply and purchase agreement for our Aptima HPV products and are being amortized over the term of the agreement.

The Company’s cost-method equity investments are carried at cost as the Company owns less than 20% of the voting equity and does not have the ability to exercise significant influence over these companies. The Company regularly evaluates the carrying value of its cost-method equity investments for impairment and whether any events or circumstances are identified that would significantly harm the fair value of the investment. The primary indicators the Company utilizes to identify these events and circumstances are the investee’s ability to remain in business, such as the investee’s liquidity and rate of cash use, and the investee’s ability to secure additional funding and the investee valuation as determined by that additional funding. In the event a decline in fair value is judged to be other-than-temporary, the Company will record an other-than-temporary impairment charge in other income (expense), net in the Consolidated Statements of Operations. During fiscal 2014, the Company recorded other-than-temporary impairment charges of $6.9 million related to certain of its cost-method equity investments to adjust their carrying amounts to fair value. No such charges were recorded in fiscal 2016 or 2015 for cost-method equity investments.

Research and Software Development Costs

Costs incurred for the research and development of the Company’s products are expensed as incurred. Nonrefundable advance payments for goods or services to be received in the future by the Company for use in research and development activities are deferred. The deferred costs are expensed as the related goods are delivered or the services are performed.

The Company accounts for the development costs of software embedded in the Company’s products in accordance with ASC 985, Software. Costs incurred in the research, design and development of software embedded in products to be sold to customers are charged to expense until technological feasibility of the ultimate product to be sold is established. The Company’s policy is that technological feasibility is achieved when a working model, with the key features and functions of the product, is available for customer testing. Software development costs incurred after the establishment of technological feasibility and until the product is available for general release are capitalized, provided recoverability is reasonably assured. Software development costs eligible for capitalization have not been significant to date.

Foreign Currency Translation

The financial statements of the Company’s foreign subsidiaries are translated in accordance with ASC 830, Foreign Currency Matters. The reporting currency for the Company is the U.S. dollar. The functional currency of the Company’s foreign subsidiaries is determined based on the guidance in ASC 830. The majority of the Company's foreign subsidiaries' functional currency is the applicable local currency, although certain of the Company's foreign subsidiaries' functional currency is the U.S. dollar based on the nature of their operations or functions. Assets and liabilities of subsidiaries whose functional currency is the local currency are translated at the exchange rate in effect at each balance sheet date. Before translation, the Company re-measures foreign currency denominated assets and liabilities, including inter-company accounts receivable and payable, into the functional currency of the respective entity, resulting in unrealized gains or losses recorded in other income (expense), net in the Consolidated Statements of Income. Revenues and expenses are translated using average exchange rates during the respective period. Foreign currency translation adjustments are accumulated as a component of other comprehensive income (loss) as a separate component of stockholders’ equity. Gains and losses arising from transactions denominated in foreign currencies are included in other income (expense), net in the Consolidated Statements of Income and were not significant in any of the reporting periods presented.

Accumulated Other Comprehensive Income

Accumulated Other Comprehensive Income (Loss)

Other comprehensive income (loss) includes certain transactions that have generally been reported in the statement of stockholders’ equity. The following tables summarize the components and changes in accumulated balances of other comprehensive income for the periods presented:



	Year Ended September 24, 2016															Year Ended September 26, 2015
	Foreign Currency Translation			Marketable Securities			Pension Plans			Hedged Interest Rate Caps			Total			Foreign Currency Translation			Marketable Securities			Pension Plans			Hedged Interest Rate Caps			Total

Ending Balance	$	(26.1	)	$	(0.3	)	$	(2.5	)	$	(3.4	)	$	(32.3	)	$	(15.7	)	$	6.9		$	(1.8	)	$	(3.9	)	$	(14.5	)

In the first quarter of fiscal 2016, the Company sold all of its shares in one of its marketable securities and recorded a realized gain of $25.1 million in other income (expense), net and resulted in reclassifying a $7.2 million gain out of other comprehensive income (loss) to other income (expense), net. In the fourth quarter of fiscal 2016, the Company recorded a $1.1 million other-than-temporary impairment charge and this amount was reclassified out of other comprehensive income (loss) to other income (expense), net.

During fiscal 2015, the Company reclassified $9.6 million out of accumulated other comprehensive income to restructuring and divestiture charges related to writing off the cumulative translation adjustment in connection with its substantial liquidation of the MRI breast coils product line (see Note 3). In addition, during fiscal 2015 the Company reclassified $7.8 million out of accumulated other comprehensive income to other (expense) income, net for the other-than-temporary impairment of a marketable security.

Derivatives, Policy

Derivatives

Interest Rate Cap - Cash Flow Hedge

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages its exposure to some of its interest rate risk through the use of interest rate caps, which are derivative financial instruments. The Company does not use derivatives for speculative purposes. For a derivative that is designated as a cash flow hedge, changes in the fair value of the derivative are recognized in accumulated other comprehensive income ("AOCI") to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings. To the extent there is any hedge ineffectiveness, changes in fair value relating to the ineffective portion are immediately recognized in earnings in other income (expense) in the Consolidated Statements of Income.

During fiscal 2015, the Company entered into separate interest rate cap agreements with multiple counter-parties to help mitigate the interest rate volatility associated with the variable rate interest on its credit facilities under its Prior Credit Agreement, which has been replaced by the new Credit Agreement (see Note 4). Interest rate cap agreements provide the right to receive cash if the reference interest rate rises above a contractual rate. The aggregate premium paid for the interest rate cap agreements was $13.2 million, which was the initial fair value of the instruments recorded in the Company's financial statements.

The critical terms of the interest rate caps were designed to mirror the terms of the Company’s LIBOR-based borrowings under the Prior Credit Agreement. The terms in the new Credit Agreement are consistent with the Prior Credit Agreement, and therefore the interest rate caps continue to be highly effective at offsetting the cash flows being hedged. The Company designated these derivatives as cash flow hedges of the variability of the LIBOR-based interest payments on $1.0 billion of principal over a three-year period, which ends on December 30, 2017.

As of September 24, 2016, the Company determined that the existence of hedge ineffectiveness, if any, was immaterial and all changes in the fair value of the interest rate caps were recorded in the Consolidated Statements of Comprehensive Income as a component of AOCI.

During fiscal 2016, $3.9 million was reclassified from AOCI to the Company's Consolidated Statements of Income related to the interest rate cap agreements. The Company expects to similarly reclassify approximately $6.9 million from AOCI to the Consolidated Statements of Income in the next twelve months.

The aggregate fair value of these interest rate caps was $1.4 million and $6.9 million at September 24, 2016 and September 26, 2015, respectively, and is included in both Prepaid expenses and other current assets and Other assets on the Company’s Consolidated Balance Sheet. Refer to Note 5 “Fair Value Measurements” below for related fair value disclosures.

Forward Foreign Currency Contracts

The Company enters into forward foreign currency exchange contracts to mitigate certain operational exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company's operations that are denominated in currencies other than the U.S. dollar, primarily the Euro, the UK Pound, the Australian dollar, the Canadian dollar and the Japanese Yen. These foreign currency exchange contracts are entered into to support transactions made in the ordinary course of business and are not speculative in nature. The contracts are generally for periods of one year or less. During fiscal 2016, the Company began to execute forward foreign currency contracts in order to mitigate its exposure to fluctuations in various currencies against its reporting currency, the U.S. dollar. The Company did not elect hedge accounting for these forward foreign currency contracts; however, the Company may seek to apply hedge accounting in future scenarios. The change in the fair value of these contracts is recognized directly in earnings as a component of other income (expense), net. During fiscal 2016, the Company recorded a realized gain of $1.5 million from settling forward foreign currency contracts, and net unrealized losses of $1.1 million on outstanding contracts.

As of September 24, 2016, the Company had outstanding forward foreign currency contracts that were not designated for hedge accounting and are used to hedge fluctuations in the U.S dollar of forecasted transactions denominated in the Euro, UK Pound, Australian Dollar, Canadian Dollar and Japanese Yen with a notional amount of $165.0 million.

Revenue Recognition

The Company generates revenue from the sale of its products, primarily medical imaging systems and diagnostic and surgical disposable products, and related services, which are primarily support and maintenance services on its medical imaging systems.

The Company recognizes product revenue upon shipment provided that there is persuasive evidence of an arrangement, there are no uncertainties regarding acceptance, the sales price is fixed or determinable, and collection of the resulting receivable is reasonably assured. Generally, the Company’s product arrangements for capital equipment sales, primarily in its Breast Health and Skeletal Health reporting segments, are multiple-element arrangements, including services, such as installation, training and support and maintenance, and multiple products. Based on the terms and conditions of the product arrangements, the Company believes that these services and undelivered products can be accounted for separately from the delivered product element as the Company’s delivered products have value to its customers on a stand-alone basis. Accordingly, revenue for services not yet performed at the time of product delivery are deferred and recognized as such services are performed. The relative selling price of any undelivered products is also deferred at the time of shipment and recognized as revenue when these products are delivered. There is no customer right of return in the Company’s sales agreements for its capital equipment.

Service revenues primarily consist of amounts recorded under service and maintenance contracts and repairs not covered under warranty, installation and training, and shipping and handling costs billed to customers. Service and maintenance contract revenues are recognized ratably over the term of the contract. Other service revenues are recognized as the services are performed.

For revenue arrangements with multiple deliverables, the Company records revenue as separate units of accounting if the delivered items have value to the customer on a stand-alone basis, and if the arrangement includes a general right of return relative to the delivered items, the delivery or performance of the undelivered items is considered probable and substantially within the Company’s control. Some of the Company’s products have both software and non-software components that function together to deliver the product’s essential functionality. The Company determined that except for its computer-aided detection (“CAD”) products and C-View product, the software element in its other products is incidental and not within the scope of the software revenue recognition rules, ASC 985-605, Software—Revenue Recognition. The Company determined that given the significance of the software component’s functionality to its CAD and C-View systems, which are sold by its Breast Health segment, these products are within the scope of the software revenue recognition rules. The Company evaluated the appropriate revenue recognition treatment of its other hardware products, including its Dimensions digital mammography systems, which have both software and non-software components that function together to deliver the products’ essential functionality (i.e., it is a tangible product), and determined they are not within the scope of ASC 985-605.

The Company is required to allocate revenue to its multiple element arrangements based on the relative fair value of each element’s selling price. The Company typically determines the selling price of its products based on its best estimate of selling prices (“ESP”) and services based on vendor-specific objective evidence of selling price (“VSOE”). The Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when sold on a stand-alone basis. In determining VSOE, the Company’s policy requires a substantial majority of selling prices for a product or service to be within a reasonably narrow range. The Company also considers the class of customer, method of distribution, and the geographies into which its products and services are sold when determining VSOE. If VSOE cannot be established, which may occur in instances when a product or service has not been sold separately, stand-alone sales are too infrequent, or product pricing is not within a relatively narrow range, the Company will generally establish the selling price using ESP to allocate arrangement consideration. The objective of ESP is to determine the price at which the Company would typically transact a stand-alone sale of the product or service. ESP is determined by considering a number of factors including Company pricing policies, internal costs and gross margin objectives, method of distribution, information gathered from experience in customer negotiations, market research and information, recent technological trends, competitive landscape and geographies.

For those arrangements accounted for under the software revenue recognition rules, ASC 985-605 generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on their relative VSOE of fair value. If VSOE does not exist for a delivered element, the residual method is applied in which the arrangement consideration is allocated to the undelivered elements based on their VSOE with the remaining consideration recognized as revenue for the delivered elements. For multiple-element software arrangements where VSOE of fair value of Post-Contract Customer Support (“PCS”) has been established, the Company recognizes revenue using the residual method at the time all other revenue recognition criteria have been met.

Within its Diagnostics segment, the Company manufactures blood screening products according to demand schedules provided by its collaboration partner, Grifols, S.A. (“Grifols”). The Company’s agreement provides that it shares a portion of Grifols’s revenue from screening blood donations. Upon shipment to Grifols, the Company recognizes product revenue at an agreed upon fixed transfer price, which is not refundable, and records the related cost of products sold. Based on the terms of the Company’s collaboration agreement with Grifols, the Company’s ultimate share of the net revenue from sales to the end user in excess of the transfer price is not known until it is reported to the Company by Grifols. On a monthly basis, Grifols reports net revenue generated during the prior month and remits an additional corresponding net payment to the Company, which is recorded as revenue at that time. This payment combined with the transfer price revenues previously recognized represents the Company’s ultimate share of net revenue under the agreement.

While the majority of its instruments are placed at customer sites, in certain instances the Company sells instruments to its clinical diagnostics customers and records sales of these instruments upon shipment or delivery, depending on the terms of the arrangement.

Within its Diagnostics business, and to a lesser extent, its GYN Surgical business, the Company provides its instrumentation (for example, the ThinPrep Processor, ThinPrep Imaging System, and the Panther and Tigris systems) and certain other hardware to customers without requiring them to purchase the equipment or enter into a lease. The Company installs the instrumentation or equipment at the customer’s site and recovers the cost of providing the instrumentation or equipment in the amount it charges for its diagnostic tests, assays and other disposables. Customers enter into a customer usage agreement and typically commit to purchasing minimum quantities of disposable products at a stated price over a defined contract term, which is typically between three and five years. Revenue is recognized over the term of the customer usage agreement as tests, assays and other disposable products are shipped or delivered, depending on the customer's arrangement.

Accounts Receivable and Reserves

The Company records reserves for doubtful accounts based upon a specific review of all outstanding invoices, known collection issues and historical experience. The Company regularly evaluates the collectability of its trade accounts receivables and performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and its assessment of the customer’s current credit worthiness.

Accounts receivable reserve activity for fiscal 2016, 2015 and 2014 was as follows:



	Balance at Beginning of Period		Charged to Costs and Expenses		Write- offs and Payments			Balance at End of Period
Period Ended:
September 24, 2016	$	11.1	$	2.0	$	(0.4	)	$	12.7
September 26, 2015	$	12.0	$	1.6	$	(2.5	)	$	11.1
September 27, 2014	$	8.8	$	4.4	$	(1.2	)	$	12.0

Cost of Service and Other Revenues

Cost of service and other revenues primarily represents payroll and related costs associated with the Company’s professional services’ employees, consultants, infrastructure costs and overhead allocations, including depreciation, rent and materials consumed in providing the service.

Stock-Based Compensation

The Company accounts for share-based payments in accordance with ASC 718, Stock Compensation (ASC 718). As such, all share-based payments to employees, including grants of stock options, restricted stock units, performance stock units and market stock units and shares issued under the Company’s employee stock purchase plan, are recognized in the Consolidated Statements of Operations based on their fair values on the date of grant.

Net Income (Loss) Per Share

Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average number of common shares and the dilutive effect of potential future issuances of common stock from outstanding stock options, restricted stock units and convertible debt determined by applying the treasury stock method. In accordance with ASC 718, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of in-the-money stock options and restricted stock units. This results in the assumed buyback of additional shares, thereby reducing the dilutive impact of equity awards.

The Company applies the provisions of ASC 260, Earnings Per Share, Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to its convertible notes, and due to the type of debt instrument issued and its accounting policy, the Company applies the treasury stock method and not the if-converted method. The dilutive impact of the Company’s convertible notes is based on the difference between the Company’s current period average stock price and the conversion price of the convertible notes, provided there is a premium. As such, dilution related to the conversion premium on the 2010 Notes, 2012 Notes and 2013 Notes is included in the calculation of diluted weighted-average shares outstanding in fiscal 2016 and 2015 to the extent each issuance is dilutive based on the average stock price during each reporting period being greater than the conversion price of the respective Notes. In fiscal 2014, only the dilution of the conversion premium on the 2010 Notes is included in diluted weighted-average shares outstanding.

A reconciliation of basic and diluted share amounts for fiscal 2016, 2015, and 2014 was as follows:



	September 24, 2016	September 26, 2015	September 27, 2014
Basic weighted average common shares outstanding	280,213	280,566	275,499
Weighted average common stock equivalents from assumed exercise of stock options and restricted stock units	2,631	2,898	2,368
Incremental shares from Convertible Notes premium	3,312	6,073	493
Diluted weighted average common shares outstanding	286,156	289,537	278,360
Weighted-average anti-dilutive shares related to:
Outstanding stock options	1,029	1,502	5,033
Restricted stock units	62	49	20

In those reporting periods in which the Company has reported net income, anti-dilutive shares generally are comprised of those stock options that either have an exercise price above the average stock price for the period or the stock options’ combined exercise price, average unrecognized stock compensation expense and assumed tax benefits upon exercise is greater than the average stock price for the period.

Product Warranties

The Company generally offers a one-year warranty for its products. The Company provides for the estimated cost of product warranties at the time product revenue is recognized. Factors that affect the Company’s warranty reserves include the number of units sold, historical and anticipated rates of warranty repairs and the cost per repair. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary.

Product warranty activity for fiscal 2016 and 2015 was as follows:



	Balance at Beginning of Period		Provisions		Settlements/ Adjustments			Balance at End of Period
Period ended:
September 24, 2016	$	5.4	$	7.1	$	(7.5	)	$	5.0
September 26, 2015	$	6.3	$	6.1	$	(7.0	)	$	5.4

Advertising Costs

Advertising costs are charged to operations as incurred. The Company does not have any direct-response advertising. Advertising costs, which include trade shows and conventions, were approximately $20.2 million, $14.4 million and $14.1 million for fiscal 2016, 2015 and 2014, respectively, and were included in selling and marketing expense in the Consolidated Statements of Income.

Recently Adopted Accounting Pronouncements

On September 27, 2015, the Company early adopted FASB ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by eliminating the requirement for entities to separate deferred income tax liabilities and assets into current and noncurrent amounts in the balance sheet. Rather, it requires deferred tax assets and liabilities to be classified as noncurrent in the balance sheet. The Company adopted this standard prospectively in the first quarter of fiscal 2016, and prior periods were not retrospectively adjusted.

On June 26, 2016, the Company retrospectively adopted FASB ASU 2015-13, Presentation of Debt Issuance Costs, which simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that debt liability consistent with the presentation of a debt discount and not recorded as separate assets. The Company adopted this standard in the fourth quarter of fiscal 2016, and the fiscal 2015 balance sheet was retrospectively recast. In fiscal 2015, the Company had $0.6 million related to current debt issuance costs recorded in prepaid expenses and other current assets and $27.0 million related to non-current debt issuance costs recorded in other assets. The adoption of this standard resulted in these amounts being reclassified as liabilities, reducing both the current portion of long-term debt and long-term debt, net of current portion at the end of fiscal 2015 by $27.6 million in total and a corresponding reduction to the aforementioned asset accounts. Debt issuance costs will no longer be recorded as an asset.

Recently Issued Accounting Pronouncements

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740). The guidance requires companies to recognize the income tax effects of intercompany sales and transfers of assets, other than inventory, in the income statement as income tax expense (or benefit) in the period in which the transfer occurs. The guidance is effective for annual periods beginning after December 15, 2017, and is applicable to the Company in fiscal 2019. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact of the adoption of ASU 2016-16 on its consolidated financial position and results of operations.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flow (Topic 230). The guidance reduces diversity in how certain cash receipts and cash payments are presented and classified in the Statements of Cash Flows. Certain of ASU 2016-15 requirements are as follows: 1) cash payments for debt prepayment or debt extinguishment costs should be classified as cash outflows for financing activities, 2) contingent consideration payments made soon after a business combination should be classified as cash outflows for investing activities and cash payment made thereafter should be classified as cash outflows for financing up to the amount of the contingent consideration liability recognized at the acquisition date with any excess classified as operating activities, 3) cash proceeds from the settlement of insurance claims should be classified on the basis of the nature of the loss, 4) cash proceeds from the settlement of Corporate-Owned Life Insurance (COLI) Policies should be classified as cash inflows from investing activities and cash payments for premiums on COLI policies may be classified as cash outflows for investing activities, operating activities, or a combination of investing and operating activities, and 5) cash paid to a tax authority by an employer when withholding shares from an employee's award for tax-withholding purposes should be classified as cash outflows for financing activities. The guidance is effective for annual periods beginning after December 15, 2017, and is applicable to the Company in fiscal 2019. Early adoption is permitted. The adoption of ASU 2016-15 is not expected to have a material effect on the Company's consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326). The guidance requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected credit losses during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The updated guidance is effective for annual periods beginning after December 15, 2019, and is applicable to the Company in fiscal 2021. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial position and results of operations.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718). The guidance changes how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize income tax effects of awards in the income statement when the awards vest or are settled. The guidance also allows an employer to repurchase more of an employee's shares than it can today for tax withholding purposes by providing for withholding at the employee's maximum rate as opposed to the minimum rate without triggering liability accounting and by allowing an entity-wide policy election to account for forfeitures as they occur. The updated guidance is effective for annual periods beginning after December 15, 2016, and is applicable to the Company in fiscal 2018. Early adoption is permitted. The adoption of ASU 2016-09 is not expected to have a material effect on the Company's consolidated financial position and results of operations, although the income tax affect from vesting of stock units and option exercises could be significant to quarterly results of operations.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance requires an entity to recognize a right-of-use asset and a lease liability for virtually all of its leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. The guidance is effective for annual periods beginning after December 15, 2018, and is applicable to the Company in fiscal 2020. Early adoption is permitted. The updated guidance requires a modified retrospective adoption. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on its consolidated financial position and results of operations.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance changes how entities measure equity investments that do not result in consolidation and are not accounted for under the equity method. Entities will be required to measure these investments at fair value at the end of each reporting period and recognize changes in fair value in net income. A practicability exception will be available for equity investments that do not have readily determinable fair values, however; the exception requires the Company to consider relevant transactions that can be reasonably known to identify any observable price changes that would impact the fair value. This guidance also changes certain disclosure requirements and other aspects of current US GAAP. This guidance is effective for annual periods beginning after December 15, 2017, and is applicable to the Company in fiscal 2019. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its consolidated financial position and results of operations.

In July 2015, the Financial Accounting Standards Board (FASB) issued guidance under ASC 330, Simplifying the Measurement of Inventory. The new guidance requires inventory to be measured at the lower of cost and net realizable value, which is defined as the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. This new guidance is effective for the Company's first quarter of fiscal 2018 and early adoption is permitted. The guidance must be applied prospectively. The Company is currently evaluating the impact of the adoption of this requirement on its consolidated financial statements but does not anticipate that adoption of this guidance will have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. This guidance focuses on a reporting company’s consolidation evaluation to determine whether certain legal entities should be consolidated. This guidance is effective for annual periods beginning after December 15, 2015, and is applicable to the Company in fiscal 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this guidance, but does not anticipate that adoption of this guidance will have a material impact on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. ASU 2014-15 requires management to evaluate, at each annual or interim reporting period, whether there are conditions or events that exist that raise substantial doubt about an entity's ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016 and is applicable to us in fiscal 2018. Earlier application is permitted. The adoption of ASU 2014-15 is not expected to have a material effect on the Company's consolidated financial statements or disclosures.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 660), which provides guidance for revenue recognition. This ASU is applicable to any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. ASU 2014-09 will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to receive in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current U.S. GAAP. These judgments may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. On July 9, 2015, the FASB voted in favor of delaying the effective date of the new standard by one year, with early adoption permitted as of the original effective date. ASU 2014-09 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017, which is fiscal 2019 for the Company. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial position and results of operations.
