NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(all tabular amounts in millions, except number of shares, which are reflected in thousands, and per share data)
(1) Basis of Presentation
The consolidated financial statements of Hologic, Inc. (“Hologic” or the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and disclosures required by U.S. generally accepted accounting principles (“GAAP”). These financial statements should be read in conjunction with the consolidated financial statements and related notes for the year ended September 27, 2014 included in the Company’s Form 10-K filed with the SEC on November 20, 2014. In the opinion of management, the financial statements and notes contain all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented.
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 preparation of financial statements in conformity with U.S. 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. Actual results could differ from management’s estimates if past experience or other assumptions do not turn out to be substantially accurate. Operating results for the three and six months ended March 28, 2015 are not necessarily indicative of the results to be expected for any other interim period or the entire fiscal year ending September 26, 2015.
Subsequent Events Consideration
The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized or unrecognized subsequent events recorded in the unaudited consolidated financial statements as of and for the three and six months ended March 28, 2015.
(2) 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 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.

Table of Contents
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 |

(3) Restructuring and Divestiture Charges

Consolidation of Diagnostics Operations
In connection with its acquisition of Gen-Probe Incorporated (“Gen-Probe”) in August 2012, the Company implemented restructuring actions to consolidate its Diagnostics operations, including streamlining product development initiatives, reducing overlapping functional areas in sales, marketing and general and administrative functions, and consolidating manufacturing resources, field services and support. As a result, the Company terminated certain employees from Gen-Probe and its legacy diagnostics business in research and development, sales, marketing and general and administrative functions. The Company also decided to move its legacy molecular diagnostics operations from Madison, Wisconsin to Gen-Probe’s facilities in San Diego, California. This transfer was completed at the end of fiscal 2014, and as a result, many of the employees in Madison were terminated. The Company recorded severance and benefit charges pursuant to ASC 420, Exit or Disposal Cost Obligations (ASC 420), beginning in fiscal 2012 through the first quarter of fiscal 2015. The Company recorded $3.0 million for severance and benefits in fiscal 2014. The Company recorded $0.5 million for facility closure costs and severance and benefits in the six months ended March 28, 2015 and $0.9 million and $1.7 million for severance and benefits in the three and six months ended March 29, 2014, respectively.
Fiscal 2015 Actions
In the first and second quarters of fiscal 2015, the Company continued to make executive management changes resulting in the termination of certain executives and employees on a worldwide basis. In addition, the Company continued to consolidate and close certain international offices.

On December 6, 2013, Stephen P. MacMillan was appointed as President, Chief Executive Officer and a director of the Company. The employment of John W. Cumming, the Company’s prior President and Chief Executive Officer, terminated upon Mr. MacMillan’s appointment. The Company provided separation benefits to Mr. Cumming pursuant to his employment letter dated July 18, 2013 resulting in a charge of $6.6 million in the first quarter of fiscal 2014, which included $4.4 million of stock-based compensation related to the acceleration of all of Mr. Cumming’s outstanding equity awards in accordance with the existing terms of Mr. Cumming’s stock-based payment arrangements. An additional $0.2 million was recorded in the second quarter of fiscal 2014 related to this action.
In the second, third, and fourth quarters of fiscal 2014, the Company continued to make executive management changes and implemented additional cost reduction initiatives resulting in the termination of certain executives and employees on a worldwide basis. In addition, in the fourth quarter of fiscal 2014, the Company decided to consolidate and close certain international offices. Severance and benefit charges under these actions were recorded pursuant to ASC 420 and ASC 712 depending on the circumstances, and the Company recorded severance and benefit charges of $16.6 million in fiscal 2014.

Credit Agreement
On December 24, 2014, the Company voluntarily pre-paid $300.0 million of its Term Loan B facility. Pursuant to ASC 470, Debt (ASC 470), the Company recorded a debt extinguishment loss of $6.7 million in the first quarter of fiscal 2015 to write-off the pro-rata amount of unamortized debt discount and deferred issuance costs related to this voluntary prepayment.
On October 31, 2013, the Company voluntarily pre-paid $100.0 million of its Term Loan B facility, which was reflected in current debt obligations as of September 28, 2013. Pursuant to ASC 470, the Company recorded a debt extinguishment loss of $3.0 million in the first quarter of fiscal 2014 to write-off the pro-rata amount of unamortized debt discount and deferred issuance costs related to this voluntary prepayment.
During the second quarter of fiscal 2014, the Company, the Guarantors, Goldman Sachs, and the Lenders entered into Refinancing Amendment No. 3 to the Credit Agreement and reduced the applicable interest rates. In connection with this refinancing, the Company voluntarily prepaid $25.0 million of the new senior secured tranche B term loan facility (the "Amended Term Loan B"). Pursuant to ASC 470, the accounting for this refinancing was evaluated on a creditor-by-creditor basis to determine whether each transaction should be accounted for as a modification or extinguishment. Certain creditors under the Credit Agreement did not participate in this refinancing transaction and ceased being creditors of the Company, and certain creditors reduced their positions. As a result, the Company recorded a debt extinguishment loss of $4.4 million in the second quarter of fiscal 2014 to write-off the pro-rata amount of unamortized debt discount and deferred issuance costs related to these creditors. For the remainder of the creditors, this transaction has been accounted for as a modification because the present value of the cash flows on a creditor-by-creditor basis between the two debt instruments was less than 10%. Pursuant to ASC 470, subtopic 50-40, third-party costs of $1.0 million related to this transaction were expensed.

Table of Contents
Borrowings outstanding under the Credit Agreement for the three and six months ended March 28, 2015 had weighted-average interest rates of 2.62% and 2.70%, respectively. The interest rates on the outstanding Term Loan A and Term Loan B borrowings at March 28, 2015 were 1.92% and 3.25%, respectively. Interest expense under the Credit Agreement totaled $14.4 million and $31.9 million for the three and six months ended March 28, 2015, respectively, which includes non-cash interest expense of $2.7 million and $5.8 million related to the amortization of the deferred issuance costs and accretion of the debt discount, respectively. Interest expense totaled $19.2 million and $39.6 million for the three and six months ended March 29, 2014, respectively, which includes non-cash interest expense of $3.2 million and $6.5 million related to the amortization of the deferred issuance costs and accretion of the debt discount, respectively.
The credit facilities contain two financial ratio covenants measured as of the last day of each fiscal quarter: a total net leverage ratio and an interest coverage ratio. As of March 28, 2015, the Company was in compliance with these covenants.
Senior Notes
The Company’s 6.25% senior notes due 2020 (the “Senior Notes”) mature on August 1, 2020 and bear interest at the rate of 6.25% per year, payable semi-annually on February 1 and August 1 of each year, commencing on February 1, 2013. The Company recorded interest expense of $16.0 million and $32.0 million in both the three and six month periods ended March 28, 2015 and March 29, 2014, respectively, which includes non-cash interest expense of $0.4 million and $0.8 million in both the three and six month periods ended March 28, 2015 and March 29, 2014, respectively, related to the amortization of the deferred issuance costs.
Convertible Notes
During the second quarter of fiscal 2015, the closing price of the Company's common stock exceeded 130% of the applicable conversion price of its 2010 Notes on at least 20 of the last 30 consecutive trading days of the quarter; therefore, holders of 2010 Notes may convert their notes during the third quarter of fiscal 2015. As such, the Company classified the $417.3 million carrying value of its 2010 Notes (which have a principal value of $450.0 million) as a current debt obligation. In the event the closing price conditions are met in the third quarter of fiscal 2015 or a future fiscal quarter, the 2010 Notes will be convertible at a holder's option during the immediately following fiscal quarter. As of March 28, 2015, the if-converted value of the 2010 Notes exceeded the aggregate principal amount by approximately $200.0 million. It is the Company's current intent and policy to settle any conversion of the Convertible Notes as if the Company had elected to make either a net share settlement or all cash election, such that upon conversion, the Company intends to pay the holders in cash for the principal amount of the 2010 Notes and, if applicable, shares of its common stock or cash to satisfy the premium based on a calculated daily conversion value.
Interest expense under the Convertible Notes is as follows:

| Three Months Ended |  | Six Months Ended
| March 28, 2015 |  | March 29, 2014 |  | March 28, 2015 |  | March 29, 2014

(5) 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 by 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 Operations.

Table of Contents
On January 7, 2015, the Company entered into two separate interest rate cap agreements to help mitigate the interest rate volatility associated with the variable rate interest on its credit facilities under the Credit Agreement. Interest rate cap agreements provide the right to receive cash if the reference interest rate rises above a contractual rate. The aggregate premium paid by the Company for the interest rate cap agreements was $6.1 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 Credit Agreement. The Company designated these derivatives as cash flow hedges of the variability of the LIBOR-based interest payments on $1.0 billion of principal for a two-year period, which ends on December 30, 2016.
As of March 28, 2015, 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 are recorded in the Consolidated Statements of Comprehensive Income as a component of AOCI.
The aggregate fair value of these interest rate caps was $3.6 million at March 28, 2015 and is included in both Prepaid expenses and other current assets and Other assets on the Company’s Consolidated Balance Sheet. Refer to Note 2 “Fair Value Measurements” above for related fair value disclosures.
The tables below present the location of the Company’s derivative financial instruments on the Consolidated Balance Sheets and the unrealized loss recognized in AOCI related to the interest rate caps for the following reporting periods (in millions):

| Balance Sheet Location |  | March 28, 2015
Assets: |  |  |
Derivative instruments designated as a cash flow hedge: |  |  |

Interest rate cap agreements | $ | (1.6 | )

During the three months ended March 28, 2015, an immaterial amount was reclassified from AOCI to the Company’s Consolidated Statements of Operations related to the derivative financial instruments. The Company expects to similarly reclassify approximately $1.1 million from AOCI to the Consolidated Statements of Operations in the next twelve months.

Litigation and Related Matters
On June 9, 2010, Smith & Nephew, Inc. ("Smith & Nephew") filed suit against Interlace Medical, Inc. ("Interlace"), which the Company acquired on January 6, 2011, in the United States District Court for the District of Massachusetts. The complaint alleged that the Interlace MyoSure hysteroscopic tissue removal device infringed U.S. patent 7,226,459. On November 22, 2011, Smith & Nephew filed suit against the Company in the United States District Court for the District of Massachusetts. The complaint alleged that use of the MyoSure hysteroscopic tissue removal system infringed U.S. patent 8,061,359. Both complaints sought permanent injunctive relief and unspecified damages. On September 4, 2012, following a two week trial, the jury returned a verdict of infringement of both the ‘459 and ‘359 patents and assessed damages of $4.0 million. A bench trial regarding the Company’s assertion of inequitable conduct on the part of Smith & Nephew with regard to the ‘359 patent was held on December 9, 2012 and oral arguments on the issue of inequitable conduct were presented on February 27, 2013. On June 27, 2013, the Court denied the Company’s motions related to inequitable conduct and allowed Smith & Nephew’s request for injunction, but ordered that enforcement of the injunction be stayed until final resolution, including appeal, of the current re-examinations of both patents at the United States Patent and Trademark Office (“USPTO”). The Court also rejected the jury’s damage award and ordered the parties to identify a mechanism for resolving the damages issue. On September 12, 2013, a status conference was held, and the Court invited the parties to submit briefs on the relevance of recent activity in the re-examinations at the USPTO. A hearing on this topic was held on October 29, 2013, and the parties

are awaiting the Court’s ruling. The Company intends to file post-trial motions seeking to reverse the jury’s verdict. On January 14, 2014, the USPTO issued a final decision that the claims of the ‘459 patent asserted as part of the litigation are not patentable. On February 13, 2014, Smith & Nephew appealed this decision to the U.S. Patent Trial and Appeal Board. On February 5, 2015, the USPTO issued a final decision that the claims of the '359 patent were not patentable. On March 5, 2015, Smith & Nephew appealed this decision to the U.S. Patent Trial and Appeal Board. At this time, based on available information regarding this litigation, the Company is unable to reasonably assess the ultimate outcome of this case or determine an estimate, or a range of estimates, of potential losses.
On March 6, 2012, Enzo Life Sciences, Inc. (“Enzo”) filed suit against the Company in the United States District Court for the District of Delaware. The complaint alleged that certain of the Company’s molecular diagnostics products, including without limitation products based on its proprietary Invader chemistry, such as Cervista HPV HR and Cervista HPV 16/18, infringe Enzo’s U.S. patent 6,992,180. The complaint seeks permanent injunctive relief and unspecified damages. The Company was formally served with the complaint on July 3, 2012, and a trial is tentatively scheduled for the fall of 2015. In January 2012, Enzo filed suit against Gen-Probe in the United States District Court for the District of Delaware. The Gen-Probe complaint alleged that certain of Gen-Probe’s diagnostics products, including products that incorporate Gen-Probe’s patented hybridization protection assay technology, such as the Aptima Combo 2 and Aptima HPV assays, infringe Enzo’s U.S. patent 6,992,180. On September 30, 2013, Enzo amended its list of accused products to include Prodesse, MilliPROBE, PACE and Procleix assays. The complaint seeks permanent injunctive relief and unspecified damages. Enzo has asserted the ‘180 patent claims against six other companies. The defendant companies are jointly arguing issues related to claim construction, and the trials are tentatively scheduled to begin in the fall of 2015. At this time, based on available information regarding this litigation, the Company is unable to reasonably assess the ultimate outcome of this case or determine an estimate, or a range of estimates, of potential losses.
On March 27, 2015, Enzo filed an additional suit against the Company in the United States District Court for the District of Delaware, The complaint alleged that certain additional Company molecular diagnostic products, including, inter alia, the Procleix Parvo/HAV assays and coagulation products, including the Invader Factor II test and the Invader Factor V test, also infringe U.S. Patent 6,992,180. The complaint further alleged that certain of the Company’s molecular diagnostic products, including Hologic’s Progensa PCA3 products, all Aptima products and all Procleix products infringe Enzo’s United States Patent 7,064,197. At this time, based on available information regarding this litigation, the Company is unable to reasonably assess the ultimate outcome of this case or determine an estimate, or a range of estimates, of potential losses.
On October 29, 2013, the Interlace stockholder representatives filed a complaint in the Delaware Court of Chancery alleging breach of contract for issues related to the payment of contingent consideration under the Interlace acquisition agreement, and sought $14.7 million in additional payments. On October 20, 2014, a trial was held in Delaware. The parties executed a settlement agreement in January 2015 for an amount less than that sought. The Company had accrued certain amounts to settle this litigation as of September 27, 2014 and the effect of this settlement was not material to the Company's financial statements.
The Company is a party to various other legal proceedings and claims arising out of the ordinary course of its business. The Company believes that except for those matters described above there are no other proceedings or claims pending against it the ultimate resolution of which would have a material adverse effect on its financial condition or results of operations. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, Contingencies. Legal costs are expensed as incurred.

Stock units | 46 |  |  | 517 |  |  | 93 |  |  | 733 |

The Company has outstanding Convertible Notes, and the principal balance and any conversion premium may be satisfied, at the Company’s option, by issuing shares of common stock, cash or a combination of shares and cash. The Company's policy is that it will settle the principal balance of the Convertible Notes in cash. As such, the Company applies the treasury stock method to these securities and the dilution related to the conversion premium of the 2010 Notes is included in the calculation of diluted weighted-average shares outstanding for fiscal 2015 as the average stock price during the quarterly periods was greater than the conversion price of the 2010 Notes.

The Company granted 1.4 million and 2.3 million restricted stock units (RSUs) during the six months ended March 28, 2015 and March 29, 2014, respectively, with weighted-average grant date fair values of $26.35 and $21.53, respectively. As of March 28, 2015, there were 3.8 million unvested RSUs outstanding with a weighted-average grant date fair value of $23.52. In addition, the Company granted 0.3 million performance stock units (PSUs) in fiscal 2015 to members of its senior management team, which have a weighted-average grant date fair value of $26.58. Each recipient of PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of three years provided the Company’s defined Return on Invested Capital metrics are achieved. The Company is recognizing compensation expense ratably over the required service period based on its estimate of the number of shares that will vest. If there is a change in the estimate of the number of shares that are probable of vesting, the Company will cumulatively adjust compensation expense in the period that the change in estimate is made.
At March 28, 2015, there was $26.8 million and $83.2 million of unrecognized compensation expense related to stock options and stock units (comprised of RSUs and PSUs), respectively, to be recognized over a weighted-average period of 3.5 years and 2.8 years, respectively.

The Company’s sales in Europe are predominantly derived from France, Germany and the United Kingdom. The Company’s sales in Asia-Pacific are predominantly derived from China, Australia and Japan. The “All others” designation includes Canada, Latin America and the Middle East.
Revenues by geography as a percentage of total revenues were as follows:

| Three Months Ended |  | Six Months Ended
| March 28, 2015 |  | March 29, 2014 |  | March 28, 2015 |  | March 29, 2014

(12) Income Taxes
In accordance with ASC 740, Income Taxes (ASC 740), each interim period is considered integral to the annual period, and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its annual effective tax rate estimated for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, adjusted for discrete taxable events that occur during the interim period.
The Company’s effective tax rate for the three and six month periods ended March 28, 2015 was 21.4% and 26.6%, respectively, compared to 42.7% and 67.9%, respectively, on pre-tax losses for the corresponding periods in the prior year. For the current three and six month periods, the effective tax rate was lower than the statutory rate primarily due to the domestic production activities deduction and reserve reversals due to a favorable income tax audit settlement. For the three and six months ended March 29, 2014, the effective tax rate was higher than the statutory rate primarily due to unbenefited foreign losses partially offset by the domestic production activities deduction.

(15) New Accounting Pronouncements
In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03 Presentation of Debt Issuance Costs. This guidance intends to simplify the presentation of debt issuance costs and more closely align the presentation of debt issuance costs under US GAAP to IFRS standards. This guidance is effective for annual periods beginning after December 15, 2015, and is applicable to the Company's fiscal 2017. Early adoption is permitted. 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 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's 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 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. ASU 2014-09 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016, which is fiscal 2018 for the Company. On April 1, 2015, the FASB voted in favor of proposing a one year delay of the effective date and to permit companies to voluntarily adopt the new standard as of the original effective date. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial position and results of operations.
In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exist. ASU 2013-11 amends the presentation requirements of ASC 740 and requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward. To the extent the tax benefit is not available at the reporting date under the governing tax law or if the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability and not combined with deferred tax assets. The ASU is effective for annual periods, and interim periods within those years, beginning after December 15, 2013, which is fiscal 2015 for the Company. The amendments are to be applied to all unrecognized tax benefits that exist as of the effective date and may be applied retrospectively to each prior reporting period presented. The adoption of ASU 2013-11 did not have a material impact on the Company's consolidated financial position or results of operations.
In March 2013, the FASB issued ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. ASU 2013-05 addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The guidance outlines the events when cumulative translation adjustments should be released into net income. The ASU is effective for annual periods, and interim periods within those years, beginning after December 15, 2013, which is fiscal 2015 for the Company. The adoption of ASU 2013-05 did not have a material impact on the Company's consolidated financial position or results of operations.

We are a developer, manufacturer and supplier of premium diagnostics products, medical imaging systems and surgical products. Our core business units are focused on diagnostics, breast health, GYN surgical and skeletal health. We sell and service our products through a combination of direct sales and service forces and a network of independent distributors and sales representatives.
We offer a wide range of diagnostic products which are used primarily to aid in the diagnosis of human diseases and screen donated human blood. Our primary diagnostics products include our Aptima family of assays, including our advanced instrumentation (Panther and Tigris), our ThinPrep system, the Rapid Fetal Fibronectin Test and our Procleix blood screening assays. The Aptima family of assays is used to detect the infectious microorganisms that cause the common sexually transmitted diseases, or STDs, chlamydia and gonorrhea, certain high-risk strains of human papillomavirus, or HPV, and Trichomonas vaginalis, the parasite that causes trichomoniasis. The ThinPrep System is primarily used in cytology applications, such as cervical cancer screening, and the Rapid Fetal Fibronectin Test assists physicians in assessing the risk of pre-term birth. In blood screening, we develop and manufacture the Procleix family of assays, which are used to detect various infectious diseases. These blood screening products are marketed worldwide by our blood screening collaborator, Grifols S.A., or Grifols, under Grifols' trademarks.
Our breast health products include a broad portfolio of breast imaging and related products and accessories, including digital mammography systems, computer-aided detection, or CAD, for mammography and minimally invasive breast biopsy devices, breast biopsy site markers, breast biopsy guidance systems and breast brachytherapy products.

We generated an increase in product revenues in both the current three and six month periods compared to the corresponding periods in the prior year. The growth was across all four of our business segments on both a domestic and worldwide basis as product revenues increased 4.9% and 5.8%, respectively, in the current year periods, although this growth was partially offset by the foreign currency exchange impact of the strengthening U.S. dollar against a number of currencies, most notably for us the Euro and UK Pound.
Diagnostics product revenues increased 2.4% and 4.4% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year due to increases in Blood Screening of $4.6 million and $17.6 million, respectively, and Molecular Diagnostics of $8.1 million and $14.5 million, respectively, partially offset by decreases of $5.9 million and $7.5 million, respectively, in our Cytology & PeriNatal business.
Blood Screening revenues increased in the current three and six month periods primarily due to volume increases related to the agreement between Grifols and the Japanese Red Cross, and restocking of certain assays for Grifols to normalize its inventory levels. The increases in Molecular Diagnostics products, and in particular our Aptima family of assays, was primarily due to increased volumes from our strategic alliance with Quest Diagnostics Incorporated, or Quest, entered into in the third quarter of fiscal 2013, and increased sales volume of our HPV screening assay. Partially offsetting these increases in the current three and six month periods was a reduction in Cervista HPV revenues as our larger customers transition to our Panther system, and slightly lower average sales prices for our Aptima products due to increased competitive pressures, and for the six month period, lower instrumentation sales due to the significant purchases made by Quest in the fourth quarter of fiscal 2013 and first quarter of fiscal 2014 in connection with the beginning of the strategic alliance referenced above. The decreases in our Cytology & PeriNatal products in the current three and six month periods compared to the corresponding periods in the prior year were primarily related to the negative foreign currency exchange impact of the strengthening U.S. dollar on our sales denominated in foreign currencies as well as some reduction in the U.S. which we primarily attribute to interval screening expansion.
Breast Health product revenues increased 6.9% and 7.0% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year. In the current three and six month periods, our digital mammography systems and related components revenue increased by $15.0 million and $35.3 million, respectively. This increase is primarily due to higher sales volume of our 3D Dimensions system on a worldwide basis. In addition, we also had higher workflow product sales primarily driven by our C-View product. As expected, we continue to experience a decline in the number of 2D systems sold in the U.S. as customers transition to the 3D Dimensions systems. These increases were partially offset by the negative foreign currency exchange impact of the strengthening U.S. dollar on our sales denominated in foreign currencies, lower MRI breast coils revenue as a result of divesting this product line in the fourth quarter of fiscal 2014, and declines as a result of the planned shutdown of our Hitec-Imaging organic photoconductor production line in fiscal 2014.

Table of Contents
GYN Surgical product revenues increased 9.8% and 8.4% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year primarily due to an increase in MyoSure system sales of $6.9 million and $12.2 million, respectively. The MyoSure system continues to gain strong market acceptance as unit sales increase globally, partially offset by lower average sales prices and product mix shift. NovaSure revenues were relatively flat in the current three and six month periods compared to the corresponding periods in the prior year as volumes increased internationally, offset by the negative foreign currency exchange impact of the strengthening U.S. dollar on our sales denominated in foreign currencies.
Skeletal Health product revenues increased 6.5% in each of the current three and six month periods compared to the corresponding periods in the prior year primarily due to increases in our Horizon osteoporosis assessment product sales on a worldwide basis, partially offset by lower volumes of our older Discovery products and the negative foreign currency impact of the strengthening U.S. dollar on our sales denominated in foreign currencies.
Product revenues by geography as a percentage of total product revenues were as follows:

| Three Months Ended |  | Six Months Ended
| March 28, 2015 |  | March 29, 2014 |  | March 28, 2015 |  | March 29, 2014
United States | 74 | % |  | 73 | % |  | 73 | % |  | 73 | %
Europe | 12 | % |  | 16 | % |  | 13 | % |  | 15 | %
Asia-Pacific | 10 | % |  | 8 | % |  | 10 | % |  | 8 | %
All others | 4 | % |  | 3 | % |  | 4 | % |  | 4 | %
| 100 | % |  | 100 | % |  | 100 | % |  | 100 | %

The increase in product revenues in the United States as a percentage of consolidated product revenues in the current three month period compared to the corresponding period in the prior year was a result of higher total product revenue in our Breast Health product lines, specifically related to the increased sales of our 3D Dimensions systems. The increase in product revenues in Asia-Pacific as a percentage of consolidated product revenues in the current three and six month periods is related to our Diagnostic product lines, specifically blood screening, primarily related to the increase in sales in Japan related to the Japanese Red Cross business under the Grifols agreement as described above. The impact of these increases and the negative impact of the strengthening U.S. dollar against the Euro and UK Pound drove the reduction in European revenues as a percentage of consolidated product revenues in the current three and six month periods.

Service and other revenues are primarily comprised of revenue generated from our field service organization to provide ongoing service, installation and repair of our products. The majority of these revenues are generated within our Breast Health segment. Service and other revenues increased 5.0% and 5.6% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year primarily due to a favorable shift in selling prices of service contracts and higher installation and training revenues related to our increased sales of 3D Dimensions systems. The increase was also driven to a lesser extent by the number of service contracts in our Breast Health business due to an increase in the installed base of our digital mammography systems.

Product revenues gross margin increased to 51.4% in the current quarter compared to 44.5% in the prior year corresponding period and increased to 51.9% in the current six month period compared to 47.5% in the corresponding period in the prior year.
Cost of Product Revenues. The cost of product revenues, excluding amortization of intangible assets, as a percentage of product revenues was 34.2% in each of the current three and six month periods compared to 35.6% and 35.1% in the corresponding periods in the prior year. Cost of product revenues as a percentage of product revenues in the current year periods decreased in Diagnostics, Breast Health, and Skeletal Health and increased in GYN Surgical compared to the corresponding periods in the prior year, resulting in the overall improvement in gross margins (exclusive of amortization of intangible assets).
Diagnostics' product costs as a percentage of revenue decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to an increase in product revenue related to the increase in Aptima assay sales and related volumes resulting in favorable manufacturing variances, favorable ThinPrep manufacturing variances, lower royalty expenses primarily for ThinPrep due to the expiration of a royalty obligation during fiscal 2014, lower Cervista HPV sales, and lower molecular diagnostics instrumentation sales, which have very low gross margins.
Breast Health’s product costs as a percentage of revenue decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the increase in 3D Dimensions sales on both a unit basis and as a percentage of total digital mammography system sales compared to our 2D systems. Our 3D Dimensions systems have higher average sales prices than our 2D systems resulting in higher gross margins. In addition, we had higher software related sales for 3D upgrades and our C-View product, which have higher gross margins than capital equipment sales. In addition, we had lower revenues from our Hitec-Imaging business, which has lower gross margins than the majority of our Breast Health products.
GYN Surgical’s product costs as a percentage of revenue increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to an increase in sales volumes for our MyoSure system and product mix shift. The MyoSure system has lower gross margins than our NovaSure system. In addition, we recorded a $4.0 million charge to write-off certain inventory that will not be utilized.
Skeletal Health’s product costs as a percentage of revenue decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to increases in volumes related to our Horizon products.
Amortization of Intangible Assets. Amortization of intangible assets relates to acquired developed technology, which is generally amortized over its estimated useful life of between 8.5 and 15 years using a straight-line method or, if reliably determinable, based on the pattern in which the economic benefits of the assets are expected to be consumed. Amortization expense increased in the current quarter partially due to an increase in developed technology as a result of certain in-process R&D projects being completed in fiscal 2014. The decrease in amortization expense in the six month period compared to the corresponding period in the prior year was primarily due to lower amortization expense from intangible assets from the Cytyc acquisition, which are being amortized based on the pattern of economic use, and the write-off of the MRI breast coils developed technology asset as a result of the divestiture of this product line in the fourth quarter of fiscal 2014 partially offset by an increase in developed technology as a result of certain in-process R&D projects being completed in 2014.

Impairment of Intangible Assets. There was no impairment of Intangible Assets in the current three and six month periods. In the second quarter of fiscal 2014, we evaluated our MRI breast coils product line asset group, which is within our Breast Health segment, for impairment due to the expectation that it would be sold or disposed of significantly before the end of its previously estimated useful life, which ultimately occurred in the fourth quarter of fiscal 2014. The undiscounted cash flows expected to be generated by this asset group over its estimated remaining life were not sufficient to recover its carrying value. We estimated the fair value of the asset group resulting in an aggregate impairment charge of $28.6 million, comprised of $27.1 million of intangible assets and $1.5 million of property and equipment. The impairment charge was allocated to the long-lived assets, resulting in $26.6 million being allocated to developed technology.

Service and other revenues gross margin was 50.3% and 49.9% in the current three and six month periods, respectively, compared to 48.3% and 47.5% in the corresponding periods in the prior year, respectively. Within our Breast Health segment, the continued conversion of a high percentage of our domestic installed base of digital mammography systems to service contracts upon expiration of the warranty period without a corresponding increase in costs to service these contracts has resulted in higher gross margins.

Research and Development Expenses. Research and development expenses increased 6.7% in each of the current three and six months periods compared to the corresponding periods in the prior year. The increases were primarily due to increased compensation, primarily from increased headcount, and additional program spend primarily for our virology product line within our molecular diagnostics business, including increased clinical spending and higher spend for prototype materials. Partially offsetting these increases is lower spend from our MRI breast coils product line as a result of the divestiture of this business in the fourth quarter of fiscal 2014. At any point in time, we have a number of different research projects and clinical trials being conducted and the timing of these projects and related costs can vary from period to period.

Selling and Marketing Expenses. Selling and marketing expenses increased 5.5% and 4.4% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year. In the current three and six month periods, selling and marketing expenses increased primarily due to increased commissions and higher spend on marketing initiatives for our breast cancer awareness and Genius 3D campaigns. These increases were partially offset by lower travel and consulting costs and lower spend from our MRI breast coils product line as a result of the divestiture of this business in the fourth quarter of fiscal 2014.
General and Administrative Expenses. General and administrative expenses decreased 2.9% and 6.4% in the current three and six month periods, respectively, compared to the corresponding periods in the prior year. The decrease in both periods was primarily due to the inclusion in the prior year periods of $4.7 million of legal and consulting fees to assist in our negotiation and response to shareholder activism that did not recur in the current year periods. In addition, the decreases in the current three and six month periods also reflect decreases in credit card fees related to customer sales, a decrease in certain non-income tax expenses and a reduction of other legal expenses. In addition, in the current six month period, bad debt expense was lower. These decreases were partially offset by higher compensation and benefit costs, primarily due to stock-based compensation.
Amortization of Intangible Assets. Amortization of intangible assets results from customer relationships, trade names, business licenses and non-compete agreements related to our acquisitions. These intangible assets are generally amortized over their estimated useful lives of between 2 and 30 years using a straight-line method or, if reliably determinable, based on the pattern in which the economic benefits of the assets are expected to be consumed utilizing expected undiscounted future cash flows. Amortization expense decreased 5.2% in the current three month period compared to the corresponding prior year period. The decrease in the current quarter was primarily due to lower amortization expense from intangible assets from the Cytyc acquisition, which are being amortized based on the pattern of economic use. For the current six month period, amortization of intangible assets remained essentially flat as the current quarter decrease previously noted was offset by the shortening of the remaining life of certain corporate trade names in the second quarter of fiscal 2014 as we decided to phase out their use.
Impairment of Intangible Assets. There was no impairment of intangible assets in the current three and six month periods of fiscal 2015. In the second quarter of fiscal 2014, we recorded an impairment charge for a trade name intangible asset related to our MRI breast coils product line as previously discussed.
Restructuring and Divestiture Charges. In fiscal 2014, we implemented cost containment measures that primarily resulted in headcount reductions and also started the process of reorganizing our senior management team and international structure, which has led to additional headcount actions in fiscal 2015. Pursuant to U.S. generally accepted accounting principles, the related severance and benefit charges are being recognized either ratably over the respective required employee service periods or up-front for contractual benefits, and other charges are being recognized as incurred. In the current three and six month periods, we recorded aggregate charges of $2.0 million and $10.0 million, respectively, related to these actions, primarily for severance and benefits and to a lesser extent facility closure costs. In the prior year three and six month periods, we recorded aggregate charges of $11.6 million and $30.0 million, respectively, primarily related to our fiscal 2014 actions including the termination of our former President and CEO and shutting down our Hitec-Imaging organic photoconductor manufacturing line. These charges recorded in fiscal 2014 primarily related to severance and benefits, and the six month period includes a $3.1 million impairment charge to record certain buildings at one of our German locations to their estimated fair value. For additional information pertaining to restructuring actions and charges, please refer to Note 3 to the consolidated financial statements contained in Part I, Item 1 of this Quarterly Report.

Interest income increased by $0.2 million in both the current three and six month periods compared to the corresponding periods in the prior year. These increases are primarily related to slightly higher average cash balances in the current year periods.

Interest expense consists primarily of the cash interest costs and the related amortization of the debt discount and deferred issuance costs on our Convertible Notes, Senior Notes and amounts borrowed under our Credit Agreement. The decreases in interest expense in the current three and six month periods compared to the corresponding periods in the prior year were primarily due to lower outstanding balances under the Credit Agreement from principal payments in fiscal 2014 and 2015, which included voluntary pre-payments, lower weighted-average interest rates due to refinancing the Term Loan B facility during fiscal 2014, and the redemption of $405.0 million in principal amount of our 2.00% Convertible Notes due 2037, or the 2007 Notes, in December 2013.

In the second quarter of fiscal 2014, we refinanced our Term Loan B facility and voluntarily prepaid $25.0 million of principal. In connection with this transaction, we recorded a debt extinguishment loss of $4.4 million for the write off of the pro-rata share of the debt discount and deferred issuance costs. Additionally, in the first quarters of each of fiscal 2015 and 2014, we made voluntary pre-payments of $300.0 million and $100.0 million on our Term Loan B facility, respectively. These prepayments are considered a partial debt extinguishment and, as a result, the pro-rata share of the debt discount and deferred issuance costs aggregating $6.7 million and $3.0 million related to these prepayments were recorded as a debt extinguishment loss in the first quarter of fiscal 2015 and 2014, respectively.

For the current three month period, this account was primarily comprised of gains of $0.5 million on the cash surrender value of life insurance contracts and mutual funds related to our deferred compensation plan, partially offset by net foreign currency exchange losses of $0.4 million. For the prior year three month period, this account was primarily comprised of an other-than temporary impairment charge for a cost-method equity investment of $3.0 million and net foreign currency exchange losses of $0.5 million.

For the current six month period, this account was primarily comprised of net foreign currency exchange losses of $1.9 million, partially offset by gains of $1.5 million on the cash surrender value of life insurance contracts and mutual funds related to our deferred compensation plan. For the prior year six month period, this account was primarily comprised of other-than-temporary impairment charges on cost-method equity investments of $3.7 million and net foreign currency exchange losses of $1.0 million, partially offset by gains of $2.7 million on the cash surrender value of life insurance contracts and mutual funds related to our deferred compensation plan.

Our effective tax rate for the current three and six month periods was 21.4% and 26.6%, respectively, compared to a provision of 42.7% and 67.9%, respectively, on pre-tax losses for the corresponding periods in the prior year. For the current three and six month periods, the effective tax rate differed from the statutory rate primarily due to the domestic production activities deduction and reserve reversals due to a favorable income tax audit settlement. For the prior year three and six month periods, the effective tax rate was higher than the statutory rate primarily due to unbenefited foreign losses, partially offset by the domestic production activities deduction.
Segment Results of Operations
We report our business as four segments: Diagnostics, Breast Health, GYN Surgical and Skeletal Health. The accounting policies of the segments are the same as those described in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended September 27, 2014. We measure segment performance based on total revenues and operating income or loss. Revenues from product sales of each of these segments are described in further detail above. The discussion that follows is a summary analysis of total revenues and the primary changes in operating income or loss by segment.

Operating Income as a % of Segment Revenue | 9.1 | % |  | 5.2 | % |  |  |  |  |  | 9.2 | % |  | 3.5 | % |  |  |  |

Diagnostics revenues increased in the current year three and six month periods compared to the corresponding periods in the prior year primarily due to the increase in product revenues discussed above.
Operating income for this business segment increased in the current three and six month periods compared to the corresponding periods in the prior year due to increased gross profit in absolute dollars and lower operating expenses. Gross profit in absolute dollars increased in the current quarter primarily due to increased Aptima sales and higher blood screening revenues as a result of the recent agreement between Grifols and the Japanese Red Cross, partially offset by a decrease in Cervista HPV volume and the negative foreign currency impact of the strengthening U.S. dollar on our sales denominated in foreign currencies. In addition, we had lower instrumentation sales in the current quarter and year to date period, which carry very low gross margins, as well as favorable manufacturing variances and lower royalty expense for ThinPrep. As a result, gross margin improved to 47.9% and 48.3% in the current three and six month periods of fiscal 2015, respectively, from 46.1% and 46.3% in the corresponding prior year periods, respectively.

Table of Contents
Operating expenses decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to a reduction in headcount in general and administrative functions and international sales and marketing, lower restructuring charges, lower bad debt expense and a decrease in non-income tax expense. These decreases were partially offset by an increase in spending on research and development for additional headcount and project spending, primarily for our virology product line, and higher intangible asset amortization expense for the current six month period from shortening the life of certain trade names.

Operating Income as a % of Segment Revenue | 29.5 | % |  | 10.8 | % |  |  |  |  |  | 27.3 | % |  | 15.0 | % |  |  |  |

Breast Health revenues increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the $10.4 million and $20.2 million increase in product revenue discussed above and the $6.4 million and $12.1 million increase in service revenue that was substantially related to additional service revenue driven by the increased sales of our 3D Dimensions systems.
Operating income for this business segment increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to an increase in gross profit in absolute dollars from higher revenue combined with a decrease in operating expenses. The overall gross margin increased to 56.3% and 55.1% in the current three and six month periods, respectively, compared to 41.1% and 46.1% in the corresponding periods in the prior year, respectively, primarily due to the inclusion in the prior year periods of a $26.6 million asset impairment charge related to our MRI breast coils product line discussed above. In addition, the current year periods reflect an increase in 3D Dimensions sales, on both a unit basis and as a percentage of total digital mammography systems, compared to our 2D systems and an increase in software related sales, which have higher gross margins. In addition, service gross margin has improved due to an increase in service contracts from our higher installed base upon expiration of the warranty period without a corresponding increase in costs.
Operating expenses decreased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to lower restructuring charges, a reduction in compensation from headcount reductions, lower intangible asset amortization expense, and lower expenses as a result of divesting our MRI breast coils product line. These expense decreases were partially offset by an increase in commissions due to higher revenues and higher marketing expenditures primarily for our breast cancer awareness and Genius 3D campaigns.

Table of Contents
Operating income for this business segment decreased in the current quarter compared to the corresponding period in the prior year primarily due to gross profit in absolute dollars that remained essentially flat while operating expenses increased. For the current six month period, operating income was flat when compared to the corresponding period in the prior year as the increase in gross profit from higher revenues was offset by higher overall operating expenses. In the current quarter, gross profit was negatively impacted by the $4.0 million charge to write-off inventory that will not be utilized. Gross margins decreased to 50.2% and 55.2% in the current three and six month periods from 55.6% and 57.6% in the corresponding periods in the prior year. In addition to the inventory impairment charge referenced above, gross margin has declined primarily due to an increase in sales volumes for our MyoSure systems and product mix shift as these sales become a higher percentage of GYN Surgical revenues. The MyoSure system has lower gross margins than our NovaSure system.
Operating expenses increased in the current three and six month periods, albeit at a slower pace than revenue, primarily due to an increase in sales force headcount, higher commissions, increased costs associated with international sales initiatives, and increased research and development expenses from higher headcount and project spend.

Skeletal Health revenues increased in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the increase in product revenues discussed above.
Operating income increased slightly in the current three and six month periods compared to the corresponding periods in the prior year primarily due to the slight increases in gross margin in absolute dollars as a result of higher sales of our higher margin Horizon product, although higher operating expenses offset most of this increase. The gross margin rate increased slightly to 43.4% in the current quarter from 43.0% in the corresponding period in the prior year. The gross margin rate for the current six month period decreased slightly to 42.8% from 43.3% in the corresponding prior year period.
LIQUIDITY AND CAPITAL RESOURCES
At March 28, 2015, we had $372.1 million of working capital, and our cash and cash equivalents totaled $670.5 million. Our cash and cash equivalents balance decreased by $65.6 million during the first six months of fiscal 2015 primarily due to debt principal payments and capital expenditures, partially offset by operating cash flows and proceeds from the exercise of stock options granted pursuant to our employee benefit programs.
In the first six months of fiscal 2015, our operating activities provided us with $311.3 million of cash, which included net income of $77.0 million, non-cash charges for depreciation and amortization aggregating $248.6 million, non-cash interest expense of $33.2 million related to our outstanding debt, stock-based compensation expense of $25.8 million, and debt extinguishment losses of $6.7 million. These adjustments to net income were partially offset by a decrease in net deferred tax liabilities of $79.1 million, primarily from the amortization of intangible assets. Cash provided by operations included a net cash inflow of $1.2 million from changes in our operating assets and liabilities. Changes in our operating assets and liabilities were driven primarily by a decrease in inventory of $29.0 million as a result of increased sales in both the Diagnostics and Breast Health segments and an overall effort to reduce inventory levels, an increase in deferred revenue of $7.3 million, and a decrease in accounts receivable of $3.3 million primarily due to the timing of cash collections. These inflows were partially offset by a decrease in accrued expenses of $19.3 million primarily due to payments of annual bonuses, legal expenses and settlements, and severance relating to restructuring actions, and a decrease in accounts payable of $17.8 million related to the timing of cash payments.
41

In the first six months of fiscal 2015, our investing activities utilized $39.0 million of cash primarily for capital expenditures of $39.7 million, which consisted primarily of the placement of equipment under customer usage agreements and purchases of manufacturing equipment and computer hardware.
In the first six months of fiscal 2015, our financing activities used cash of $332.3 million primarily due to $357.5 million in debt principal payments comprised of $300.0 million in voluntary prepayments and $57.5 million of scheduled principal payments under our Credit Agreement, and $12.1 million for employee-related taxes withheld for the net share settlement of vested restricted stock units. Partially offsetting these uses of cash were proceeds of $37.4 million from our equity plans, primarily from the exercise of stock options.
Debt
We had total recorded debt outstanding of $3.94 billion at March 28, 2015, which is comprised of amounts outstanding under our amended Credit Agreement of $1.68 billion (principal $1.69 billion), Senior Notes of $1.00 billion and Convertible Notes of $1.26 billion (principal $1.32 billion).
Credit Agreement
The facilities under the Credit Agreement initially consisted of:

• | $1.0 billion senior secured tranche A term loan, or Term Loan A, with a final maturity date of August 1, 2017;

• | $1.5 billion secured tranche B term loan, or Term Loan B, with a final maturity date of August 1, 2019; and

• | $300.0 million secured revolving credit facility, or Revolving Facility, with a final maturity date of August 1, 2017.

The credit facilities are secured by first-priority liens on, and a first-priority security interest in, substantially all of our assets and the assets of the Guarantors, including all of the capital stock of substantially all of the U.S. subsidiaries owned by us and the Guarantors, 65% of the capital stock of certain of our first-tier foreign subsidiaries and all intercompany debt.
We are required to make scheduled principal payments under the Term Loan A facility in increasing amounts, which is currently $25.0 million per three month period and will increase to $50.0 million per three month period commencing October 31, 2015, and under the Term Loan B facility in equal installments of $3.75 million per three month period until maturity. The remaining principal balance of $400 million for Term Loan A and $770 million for Term Loan B is due at maturity. Any amounts outstanding under the Revolving Facility are due at maturity. We are required to make principal repayments first, pro rata among the term loan facilities, and second to the Revolving Facility from specified excess cash flows from operations and from the net proceeds of specified types of asset sales, debt issuances, insurance recoveries and equity offerings. Subject to certain limitations, we may voluntarily pre-pay any of the credit facilities without premium or penalty.
The amended Credit Agreement contains affirmative and negative covenants customarily applicable to senior secured credit facilities, including covenants restricting our ability and the ability of the Guarantors, subject to negotiated exceptions, to incur additional indebtedness and additional liens on their assets, engage in mergers or acquisitions or dispose of assets, enter into sale-leaseback transactions, pay dividends, repurchase or redeem capital stock or make other distributions, voluntarily prepay other indebtedness, enter into transactions with affiliated persons, make investments, and change the nature of their businesses.
The credit facilities contain two financial ratio covenants measured as of the last day of each fiscal quarter: a total net leverage ratio and an interest coverage ratio. As of March 28, 2015, we were in compliance with these covenants.
Senior Notes
On August 1, 2012, we issued $1.0 billion aggregate principal amount of Senior Notes. The Senior Notes are our general senior unsecured obligations and are guaranteed on a senior unsecured basis by the Guarantors. The Senior Notes mature on August 1, 2020 and bear interest at the rate of 6.25% per year, payable semi-annually on February 1 and August 1 of each year, commencing on February 1, 2013.
We may redeem up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds of certain equity offerings at any time and from time to time before August 1, 2015, at a redemption price equal to 106.250% of the aggregate principal amount so redeemed, plus accrued and unpaid interest, if any, to the redemption date. We also have the option to redeem the Senior Notes on or after: August 1, 2015 through July 31, 2016 at 103.125% of par; August 1, 2016
42

through July 31, 2017 at 102.083% of par; August 1, 2017 through July 31, 2018 at 101.042% of par; and August 1, 2018 and thereafter at 100% of par. In addition, if we undergo a change of control, as provided in the indenture, we will be required to make an offer to purchase each holder’s Senior Notes at a price equal to 101% of the aggregate principal amount of the Senior Notes, plus accrued and unpaid interest, if any, to the repurchase date.
Convertible Notes
At March 28, 2015, our Convertible Notes, in the aggregate principal amount of $1.32 billion, are recorded at $1.26 billion, which is net of the unamortized debt discount attributed to the embedded conversion feature of the Convertible Notes. These notes consist of:

• | $450 million of our 2.00% Convertible Exchange Senior Notes due 2037 issued in November 2010, which we refer to as the 2010 Notes;

• | $500 million of our 2.00% Convertible Senior Notes due 2042 issued in March 2012, which we refer to as the 2012 Notes; and

• | $370 million of our 2.00% Convertible Senior Notes due 2043 issued in February 2013, which we refer to as the 2013 Notes.

Holders may require us to repurchase the 2010 Notes on each of December 15, 2016, 2020, 2025, on December 13, 2030 and on December 14, 2035, or upon a fundamental change, as provided in the indenture for the 2010 Notes, at a repurchase price equal to 100% of their accreted principal amount, plus accrued and unpaid interest.
During the second quarter of fiscal 2015, the closing price of our common stock exceeded 130% of the applicable conversion price of our 2010 Notes on at least 20 of the last 30 consecutive trading days of the quarter; therefore, holders of the 2010 Notes may convert their notes during the third quarter of fiscal 2015. As such, we classified the $417.3 million in carrying value ($450.0 million principal value) of our 2010 Notes as a current debt obligation. In the event the closing price conditions are met in the third quarter of fiscal 2015 or a future fiscal quarter, the 2010 Notes will be convertible at a holder's option during the immediately following fiscal quarter. As of March 28, 2015, the if-converted value of the 2010 Notes exceeded the aggregate principal amount by approximately $200 million. It is our current intent and policy to settle any conversion of the Convertible Notes as if we had elected to make either a net share settlement or all cash election, such that upon conversion, we intend to pay the holders in cash for the principal amount of the 2010 Notes and, if applicable, shares of our common stock or cash to satisfy the premium based on a calculated daily conversion value.
Holders may require us to repurchase the 2012 Notes on each of March 1, 2018, 2022, 2027 and 2032, and on March 2, 2037, or upon a fundamental change, as provided in the indenture for the 2012 Notes, at a repurchase price equal to 100% of their accreted principal amount, plus accrued and unpaid interest.
Holders may require us to repurchase the 2013 Notes on each of December 15, 2017, 2022, 2027, 2032 and 2037, or upon a fundamental change, as provided in the indenture for the 2013 Notes, at a repurchase price equal to 100% of their accreted principal amount, plus accrued and unpaid interest.
We may redeem any of the 2010 Notes, 2012 Notes and 2013 Notes beginning December 19, 2016, March 6, 2018 and December 15, 2017, respectively. We may redeem all or a portion of the 2010 Notes, 2012 Notes, and 2013 Notes (i.e., in cash or a combination of cash and shares of our common stock) at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the applicable redemption date.
We have recorded deferred tax liabilities related to our convertible notes original issuance discount, representing the spread between the stated cash coupon rate and the higher interest rate that is deductible for tax purposes based on the type of security. When our convertible notes are extinguished, we are required to recapture the original issuance discount previously deducted for tax purposes.
Stock Repurchase Program
On November 11, 2013, we announced that our Board of Directors authorized the repurchase of up to $250.0 million of our outstanding common stock over the next three years. Under the stock repurchase program, we are authorized to repurchase, from time-to-time, shares of our outstanding common stock on the open market or in privately negotiated transactions in the United States. The timing and amount of stock repurchases will be determined based upon our evaluation of market conditions and other factors. The stock repurchase program may be suspended, modified or discontinued at any time, and we have no
43

obligation to repurchase any amount of our common stock under the program. Through March 28, 2015, we had not repurchased any shares of our common stock under this program.
Legal Contingencies
We are currently involved in several legal proceedings and claims. In connection with these legal proceedings and claims, management periodically reviews estimates of potential costs to be incurred by us in connection with the adjudication or settlement, if any, of these proceedings. These estimates are developed in consultation with outside counsel and are based on an analysis of potential litigation outcomes and settlement strategies. In accordance with ASC 450, Contingencies, loss contingencies are accrued if, in the opinion of management, an adverse outcome is probable and such financial outcome can be reasonably estimated. It is possible that future results for any particular quarter or annual period may be materially affected by changes in our assumptions or the effectiveness of our strategies relating to these proceedings.
Future Liquidity Considerations
We believe that our cash and cash equivalents, cash flows from operations and the cash available under our Revolving Facility will provide us with sufficient funds in order to fund our expected normal operations and debt payments, including interest and potential payouts for any convertible notes for which conversion is triggered by the holder, over the next twelve months. Our longer-term liquidity is contingent upon future operating performance. We may also require additional capital in the future to fund capital expenditures, repayment of debt and related deferred tax liabilities, as applicable, acquisitions, strategic transactions or other investments. As described above, we have significant indebtedness outstanding under our Credit Agreement, Senior Notes and Convertible Notes. These capital requirements could be substantial. For a description of risks to our operating performance and our indebtedness, see “Risk Factors” in Part I, Item 1A in our Annual Report on Form 10-K for the fiscal year ended September 27, 2014.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The discussion and analysis of our financial condition and results of operations are based upon our interim consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition for multiple element arrangements, allowance for doubtful accounts, reserves for excess and obsolete inventories, 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 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 and recoverability of our net deferred tax assets and related valuation allowances. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates if past experience or other assumptions do not turn out to be substantially accurate. Any differences may have a material impact on our financial condition and results of operations. For a discussion of how these and other factors may affect our business, see the “Cautionary Statement” above and “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 27, 2014.
The critical accounting estimates that we believe affect our more significant judgments and estimates used in the preparation of our consolidated financial statements presented in this report are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations and in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended September 27, 2014. There have been no material changes to our critical accounting policies or estimates from those set forth in our Annual Report on Form 10-K for the fiscal year ended September 27, 2014.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Financial Instruments, Other Financial Instruments, and Derivative Commodity Instruments. Financial instruments consist of cash equivalents, accounts receivable, publicly-traded equity securities, cost-method equity investments, mutual funds, insurance contracts and related deferred compensation plan liabilities, interest rate caps, accounts payable and debt obligations. Except for our outstanding Convertible Notes and Senior Notes, the fair value of these financial instruments approximates their carrying amount. As of March 28, 2015, we have $1.32 billion in principal amount of Convertible Notes outstanding, which are comprised of our 2010 Notes with a principal amount of $450.0 million, our 2012 Notes with a principal amount of $500.0 million and our 2013 Notes with a principal amount of $370.0 million. The Convertible Notes are recorded net of the unamortized debt discount on our consolidated balance sheets. The fair value of our 2010 Notes, 2012 Notes and 2013 Notes as of March 28, 2015 was approximately $652.3 million, $613.3 million and $430.2 million, respectively. Amounts

Table of Contents
outstanding under our Credit Agreement aggregating $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, we believe the carrying amount of these obligations approximates fair value. The fair value of our Senior Notes is approximately $1.04 billion.
Primary Market Risk Exposures. Our primary market risk exposure is in the areas of interest rate risk and foreign currency exchange rate risk. We incur interest expense on borrowings outstanding under our Convertible Notes, Senior Notes and Credit Agreement. The Convertible Notes and Senior Notes have fixed interest rates. Borrowings under our Credit Agreement bear interest at a rate per annum, at our option, initially, with respect to all loans made under Term Loan A: (i) at the Base Rate plus 1.00% per annum, or (ii) at the Adjusted Eurodollar Rate (i.e., the LIBOR rate) plus 2.00%, and with respect to loans made under Term Loan B: (i) at the Base Rate, with a floor of 1.75%, plus 1.50%, or (ii) at the Adjusted Eurodollar Rate (i.e., the LIBOR rate), with a floor of 0.75%, plus 2.50%.
As of March 28, 2015, there was $1.69 billion in aggregate principal amount outstanding under the Credit Agreement comprised of $850 million under the Term Loan A facility and $837.5 million under the Term Loan B facility. Since these debt obligations are variable rate instruments, our interest expense associated with these instruments is subject to change. A 10% adverse movement (increase in LIBOR rate) would increase annual interest expense by less than $1.0 million due to the low current interest rate environment and the floor on our Term Loan B facility. On January 7, 2015, we entered into two separate interest rate cap agreements to help mitigate the interest rate volatility associated with the variable rate interest on these facilities. The critical terms of the interest rate caps were designed to mirror the terms of our LIBOR-based borrowings under the Credit Agreement. We designated these derivatives as cash flow hedges of the variability of the LIBOR-based interest payments on $1.0 billion of principal for a two-year period, which ends on December 30, 2016.
The return from cash and cash equivalents will vary as short-term interest rates change. A hypothetical 10% increase or decrease in interest rates, however, would not have a material adverse effect on our business, financial condition or results of operations.
Foreign Currency Exchange Risk. Our international business is subject to risks, including, but not limited to: unique economic conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate volatility. Accordingly, our future results could be materially adversely impacted by changes in these or other factors.
We conduct business worldwide and maintain sales and service offices outside the United States as well as manufacturing facilities in Costa Rica, Germany, England, Canada and China. Our international sales are denominated in a number of currencies, primarily the Euro, U.S. dollar and Renminbi. The expenses of our international offices are denominated in local currencies, except at our Costa Rica subsidiary, where the majority of the business is conducted in U.S. dollars. Fluctuations in foreign currency rates could affect our sales, cost of goods and operating margins and could result in exchange losses. In addition, currency devaluations can result in a loss if we hold deposits of that currency.
We believe that the operating expenses of our international subsidiaries that are incurred in local currencies will not have a material adverse effect on our business, results of operations or financial condition. Our operating results and certain assets and liabilities that are denominated in the Euro are affected by changes in the relative strength of the U.S. dollar against the Euro. Our expenses, denominated in Euros, are positively affected when the U.S. dollar strengthens against the Euro and adversely affected when the U.S. dollar weakens. However, we believe that the foreign currency exchange risk is not significant. A hypothetical 10% increase or decrease in foreign currencies that we transact in would not have a material adverse impact on our business, financial condition or results of operations.

Item 4. Controls and Procedures.
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As of March 28, 2015, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of March 28, 2015.
An evaluation was also performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
