NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
1. BASIS OF PRESENTATION
General
The terms “we,” “our,” “us,” “Company” and “Integra” refer to Integra LifeSciences Holdings Corporation, a Delaware corporation, and its subsidiaries unless the context suggests otherwise.
In the opinion of management, the June 30, 2016 unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the financial position, results of operations and cash flows of the Company. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K. The December 31, 2015 consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. Operating results for the three and six-month periods ended June 30, 2016 are not necessarily indicative of the results to be expected for the entire year.
On July 1, 2015, the Company completed the distribution of 100% of the outstanding common shares of SeaSpine Holdings Corporation ("SeaSpine") to Integra shareholders who received one share of SeaSpine common stock for every three shares of Integra common stock held as of the close of business on the record date, June 19, 2015. The Company has classified the results of operations and cash flows of SeaSpine as discontinued operations for the three- and six-month periods ended June 30, 2015 presented in the Company's Form 10-Q. Unless indicated otherwise, the information in the Notes to the condensed consolidated financial statements relates to the Company's continuing operations. Refer to Note 2 - Discontinued Operations, for additional information regarding the distribution.
The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent liabilities, and the reported amounts of revenues and expenses. Significant estimates affecting amounts reported or disclosed in the consolidated financial statements include allowances for doubtful accounts receivable and sales returns and allowances, net realizable value of inventories, valuation of intangible assets including in-process research and development, amortization periods for acquired intangible assets, discount rates and estimated projected cash flows used to value and test impairments of long-lived assets and goodwill, estimates of projected cash flows and depreciation and amortization periods for long-lived assets, computation of taxes, valuation allowances recorded against deferred tax assets, the valuation of stock-based compensation, valuation of derivative instruments, valuation of the equity component of convertible debt instruments, valuation of contingent liabilities, the fair value of debt instruments and loss contingencies. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the current circumstances. Actual results could differ from these estimates.
Recently Issued Accounting Standards
In May 2014, the FASB issued Update No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should: 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. This update will become effective for all annual periods and interim reporting periods beginning after December 15, 2017. Early adoption as of January 1, 2017 is permitted. The Company is in the process of evaluating the impact of this standard on its financial statements.
In June 2014, the FASB issued Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718). The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period.

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (continued)
The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. This update is effective for annual and interim reporting periods beginning after December 15, 2015. The Company adopted this guidance effective January 1, 2016 on a prospective basis. The implementation of the amended guidance did not have a material impact on the Company's consolidated financial position or results of operations.
In August 2014, the FASB issued Update No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The amendment requires management to evaluate, for each annual and interim reporting period, whether there are conditions and events, considered in the aggregate, 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 or are available to be issued. If substantial doubt is raised, additional disclosures around management’s plan to alleviate these doubts are required. This update will become effective for all annual periods and interim reporting periods beginning after December 15, 2016. The implementation of the amended guidance is not expected to have an impact on current disclosures in the financial statements.
In April 2015, the FASB issued Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs. The amendment requires that all costs incurred to issue certain debt be presented in the balance sheet as a direct deduction from the carrying value of the debt. The new standard is limited to the presentation of debt issuance costs and does not affect the recognition or measurement of debt issuance costs. This update is effective for all annual periods and interim reporting periods beginning after December 15, 2015. The Company adopted this guidance effective January 1, 2016 on a retrospective basis. The implementation of the amended guidance did not have a material impact on the consolidated results of operations and resulted in a reclassification of a portion of the debt issuance costs from other long-term assets to long-term debt.
In July 2015, the FASB issued Update No. 2015-11, Simplifying the Measurement of Inventory. The amendment requires an entity to measure inventory that is within the scope of this amendment at the lower of cost and net realizable value. Existing impairment models will continue to be used for inventories that are accounted for using the last-in first-out (“LIFO”) method. The ASU requires prospective adoption for inventory measurements for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years for public business entities. Early adoption is permitted. The implementation of the amended guidance is not expected to have a material impact on the consolidated financial position or results of operations.
In August 2015, the FASB issued Update No. 2015-15, Interest - Imputation of Interest. The amendment requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU No. 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU No. 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity's deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This update is effective for all annual periods and interim reporting periods beginning after December 15, 2015. The Company adopted this guidance effective January 1, 2016 on a retrospective basis. The implementation of the amended guidance did not have a material impact on the consolidated financial position or results of operations.
In September 2015, the FASB issued Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. The amendment requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This update also requires an entity to present separately in the income statement or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This update is effective for all annual periods and interim reporting periods beginning after December 15, 2015. The new standard must be applied prospectively to adjustments to provisional amounts that occur after the effective date. The implementation of the amended guidance did not have a material impact on the consolidated results of operations or disclosures in the financial statements.
In November 2015, the FASB issued Update No. 2015-17, Income Taxes (Topic 740). Under current accounting guidance an entity is required to separate deferred income tax liabilities and assets into current and non-current amounts in a classified statement of financial position. The amendment requires that an entity present all deferred tax assets and liabilities as non-current in a classified statement of financial position. This update will become effective for all annual periods and interim reporting periods beginning after December 15, 2016, however the Company adopted this guidance effective December 31, 2015 on a prospective basis.
In February 2016, the FASB issued Update No. 2016-02, Leases (Topic 842). Under current accounting guidance an entity is not required to report operating leases on the balance sheet. The amendment requires that lessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability (other than leases that meet the definition of a "short-term lease"). This update will become effective for all annual periods and interim reporting periods beginning after December 15,

2018. The new standard must be adopted using a modified retrospective transition. Early adoption is permitted. The Company is in the process of evaluating the impact of this standard on its financial statements.
In March 2016, the FASB issued Update No. 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718) (ASU 2016-09), which simplifies several aspect of the accounting for share-based payment. Under current accounting guidance an entity is required to report excess tax benefits and tax deficiencies, to the extent of previous windfalls, in equity when an award is settled. A tax benefit currently only recognized when it is realized. Excess tax benefits at settlements are currently reported as cash inflows from financing activities. The amendment requires that an entity present all excess tax benefits and all tax deficiencies as income tax expense or benefit in the statement of operations to be applied using a prospective transition method. Related tax effects of share-based payment settlements are to be presented as cash inflows from operating activities with a transition method of either a prospective or retrospective transition method. The amendment also removes the requirement to delay recognition of an excess tax benefit until the tax benefit is realized. A modified retrospective transition method must be applied for this provision of amendment. ASU 2016-09 allows the Company to elect to account for forfeitures either based on an estimate of the number of awards for which the requisite service period is not expected be rendered with a true-up for actual forfeitures or to account for forfeitures as they occur. The amendment also requires cash outflows attributable to tax withholdings on the net settlement of equity-classified awards to be classified in financing cash flows, with any changes to be applied retrospectively. ASU 2016-09 is effective for all annual periods and interim reporting periods beginning after December 15, 2016. Early adoption is permitted.
The Company elected to early adopt ASU 2016-09 during the quarter ended June 30, 2016, which requires any adjustments to be reflected as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. The Company elected to account for forfeitures as they occur. The impact in retained earnings as of December 31, 2015 from this provision was not significant. Amendments related to accounting for excess tax benefits have been adopted prospectively, resulting in recognition of excess tax benefits against income tax expenses rather than additional paid-in capital of $1.2 million and $3.0 million for the three and six months ended June 30, 2016, respectively. Amendments related to the condensed consolidated statement of cash flows have been adopted retrospectively. As a result of this adoption, the excess tax settlement and taxes on net settlement of $7.2 million was included in net cash provided by operating activities for the six months ended June 30, 2016. The six months ended June 30, 2015 was adjusted as follows: a $9.9 million increase to net cash provided by operating activities and a $9.9 million decrease in net cash provided by financing activities.
There are no other recently issued accounting pronouncements that are expected to have a material effect on the Company's financial position, results of operations or cash flows.
2. DISCONTINUED OPERATIONS
On October 29, 2014, Integra's Board of Directors approved the announcement of a plan to separate the Company's spine and orthobiologics businesses, now known as SeaSpine Holdings Corporation, from Integra as a new, publicly traded medical technology company focused on the design, development and commercialization of surgical solutions for the treatment of patients suffering from spinal disorders. Integra's board of directors based this determination, in part, on its belief that the tax-free distribution of SeaSpine's shares to Integra stockholders is the most efficient manner to separate the business from Integra's other medical technology businesses. On November 3, 2014, the Company announced its intention to separate its spine business, which was previously a separate reportable segment. On July 1, 2015, the Company completed the distribution of 100% of the outstanding common stock of SeaSpine to Integra's stockholders, who received one share of SeaSpine common stock for every three shares of Integra common stock held as of the close of business on the record date, June 19, 2015. The Company and SeaSpine share three board members, including the chair of Integra’s board of directors, who is lead director for SeaSpine. The separation agreement provided SeaSpine with approximately $47.0 million of total cash immediately following the distribution. No gain or loss was recognized on the part of the Company or shareholders as a result of the distribution resulting from the separation of the spine business.
The historical results of operations, cash flows, and statement of financial position of SeaSpine have been presented as discontinued operations in the condensed consolidated financial statements and prior periods have been restated. Discontinued operations include results of SeaSpine's business except for certain allocated corporate overhead costs and certain costs associated with transition services provided by Integra to SeaSpine. These allocated costs remain part of continuing operations. Discontinued operations also include other costs incurred by Integra to separate SeaSpine from the fourth quarter of 2014 through the second quarter of 2015. These costs include transaction charges, advisory and consulting fees, and information system expenses. Since the third quarter of 2015, SeaSpine is a stand-alone public company that separately reports its financial results. Due to differences between the basis of presentation for discontinued operations and the basis of presentation as a stand-alone company, the financial results of SeaSpine included within discontinued operations for the Company may not be indicative of actual financial results of SeaSpine as a stand-alone company.

The removal of SeaSpine's net assets and unrealized accelerated currency translation adjustment was presented as a reduction in Integra's retained earnings.
In order to effect the separation and govern Integra's relationship with SeaSpine after the separation, the Company entered into a Separation and Distribution Agreement and other agreements, including a Tax Matters Agreement, an Employee Matters Agreement, several supply agreements, and a Transition Services Agreement. The Separation and Distribution Agreement governs the separation of the spine business, the transfer of assets and other matters related to the Company's relationship with SeaSpine.
The Tax Matters Agreement governs the respective rights, responsibilities and obligations of SeaSpine and Integra with respect to taxes, tax attributes, tax returns, tax proceedings and certain other tax matters.
The Employee Matters Agreement governs the compensation and employee benefit obligations with respect to the current and former employees and non-employee directors of SeaSpine and Integra, and generally allocates liabilities and responsibilities relating to employee compensation, benefit plans and programs. The Employee Matters Agreement provides that employees of SeaSpine will no longer participate in benefit plans sponsored or maintained by Integra. In addition, the Employee Matters Agreement provides that each of the parties will be responsible for their respective former and current employees and compensation plans for such current employees.
The Company entered into several Supply Agreements in which SeaSpine engaged Integra to be the product supplier of Integra's former Integra Mozaik TM product line ("Mozaik") for a three-year period following the separation, after which there will be no defined terms and this will be considered a normal purchase/sale arrangement. This product line has been licensed to SeaSpine in conjunction with the spin-off. Prior to the spin-off, sales of Mozaik products from an Integra facility to a SeaSpine facility were eliminated in Integra's historical consolidated financial results of operations. The revenue and cost of goods sold related to prior sales of Mozaik to SeaSpine have been restated and are presented in Integra's continuing operations as results of operations. The Company has recorded $0.5 million and $2.0 million in revenue related to the sale of Mozaik products for the three-month period ended June 30, 2016 and 2015, respectively, and $0.6 million and $3.2 million, respectively for the six-month periods ended June 30, 2016 and 2015. The Company has recorded the related cost of goods sold of approximately $0.5 million and $2.0 million in for the three-months periods ended June 30, 2016 and 2015, respectively and $0.6 million and $3.2 million for the six-month periods ended June 30, 2016 and 2015, respectively, in its continuing operations.
Under the terms of the Transition Services Agreement, the Company agreed to provide administrative, site services, information technology systems and various other corporate and support services to SeaSpine over various periods after the separation on a cost or cost-plus basis. The most significant components of the service income are the provision of information systems and legal services, which were substantially completed during the first quarter of 2016. In the three- and six-month periods ended June 30, 2016 other income (expense), net, includes a minimal amount and $0.3 million, respectively of income in respect of the provision of services to SeaSpine.

Tekmed
On December 15, 2015, the Company acquired the assets of Tekmed Instruments S.p.A ("Tekmed") for an aggregate purchase price of $14.1 million including a minimal amount of working capital and purchase adjustment which was recorded as an adjustment to assumed liabilities. Tekmed was a distributor of the Company's and third-party products in Italy and focuses on neurosurgery and neurotrauma, along with representation in plastic and reconstructive surgery, cardiovascular surgery, image diagnostics, general surgery, anesthesia and intensive care, interventional radiology, and proton therapy. This acquisition enables the Company to sell directly into the market to support our Specialty Surgical Solutions division's growth in Italy along with other key Integra franchises.
The Company recorded revenue for Tekmed of approximately $1.2 million and $2.4 million related to third party products in the consolidated statements of operations for the three and six months ended June 30, 2016. The net income or loss attributable to this acquisition cannot be identified on a stand-alone basis because it is in the process of being integrated into the Company's operations.
The following summarizes the preliminary allocation of the purchase price as of June 30, 2016 based on the fair value of the assets acquired and liabilities assumed:

Identifiable intangible assets are initially recorded at fair market value at the time of acquisition using an income or cost approach.
6. DEBT
Amended and Restated Senior Credit Agreement
On August 28, 2015, the Company entered into a second amendment (the “Second Amendment”) to the certain Third Amended and Restated Credit Agreement, dated as of July 2, 2014 among the Company, a syndicate of lending banks, Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, Wells Fargo Bank, National Association, as Syndication Agent, and HSBC Bank USA, National Association, Royal Bank of Canada, Citizens Bank, National Association, DNB Capital LLC, Crédit Agricole-Corporate and Investment Bank, and TD Bank, N.A., as Co-Documentation Agents.
The Second Amendment creates an aggregate principal amount of up to $1.1 billion available to the Company through the following facilities:

i. | a $750.0 million revolving credit facility, which includes a $60.0 million sublimit for the issuance of standby letters of credit and a $60.0 million sublimit for swingline loans, and

ii. | a $350.0 million term loan facility.

In connection with the Second Amendment, the Company borrowed $200.0 million of incremental term loans as permitted under the original terms of the Senior Credit Facility to repay a portion of the Company's outstanding revolving loans. Additionally, the Second Amendment (i) enables the Company to incur up to $200.0 million of incremental loans in the future and (ii) modifies the consolidated leverage ratio covenant in the Credit Agreement. The July 2014 amended and restated Senior Credit Facility extended the maturity date of the prior facility from June 8, 2016 to July 2, 2019.
13

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (continued)
Borrowings under the Senior Credit Facility bear interest, at the Company’s option, at a rate equal to:

i. | the Eurodollar Rate (as defined in the amendment and restatement) in effect from time to time plus the applicable rate (ranging from 1.00% to 1.75%), or

ii. | the highest of:

1. | the weighted average overnight Federal funds rate, as published by the Federal Reserve Bank of New York, plus 0.50%,

2. | the prime lending rate of Bank of America, N.A., or

3. | the one-month Eurodollar Rate plus 1.00%.

The applicable rates are based on the Company’s consolidated total leverage ratio (defined as the ratio of (a) consolidated funded indebtedness less cash in excess of $40.0 million that is not subject to any restriction of the use or investment thereof to (b) consolidated EBITDA) at the time of the applicable borrowing.
The Company will also pay an annual commitment fee (ranging from 0.15% to 0.30%, based on the Company’s consolidated total leverage ratio) on the daily amount by which the revolving credit facility exceeds the outstanding loans and letters of credit under the credit facility.
The Senior Credit Facility is collateralized by substantially all of the assets of the Company’s U.S. subsidiaries, excluding intangible assets. The Senior Credit Facility is subject to various financial and negative covenants and at June 30, 2016 the Company was in compliance with all such covenants. The Company capitalized $1.4 million of incremental financing costs in 2015 in connection with the modifications of the Senior Credit Facility.
At June 30, 2016 and December 31, 2015, there was $140.0 million and $150.0 million outstanding, respectively, under the revolving credit component of the Senior Credit Facility at a weighted average interest rate of 2.1% and 1.9%, respectively. At June 30, 2016 and December 31, 2015, there was $342.5 million and $346.2 million outstanding, respectively, under the term loan component of the Senior Credit Facility at a weighted average interest rate of 2.1% and 1.8%, respectively. At June 30, 2016, there was approximately $610.0 million available for borrowing under the Senior Credit Facility.
The fair value of outstanding borrowings of the Senior Credit Facility's revolving credit facility and term loan components at June 30, 2016 was approximately $134.5 million and $330.3 million, respectively. These fair values were determined by using a discounted cash flow model based on current market interest rates available to the Company. These inputs are corroborated by observable market data for similar liabilities and therefore classified within Level 2 of the fair value hierarchy. Level 2 inputs represent inputs that are observable for the asset or liability, either directly or indirectly and are other than active market observable inputs that reflect unadjusted quoted prices for identical assets or liabilities. The Company considers the balance to be long-term in nature based on its current intent and ability to repay the borrowing outside of the next twelve-month period.
Contractual repayments of the term loan began September 30, 2015 and are due as follows:

Year Ended December 31, |  | Principal Repayment
|  | (In thousands)
2016 |  | $ | 10,625 |

|  | $ | 342,500 |

The outstanding balance of revolving credit component of the Senior Credit Facility is due on July 2, 2019.
2016 Convertible Senior Notes
On June 15, 2011, the Company issued $230.0 million aggregate principal amount of its 1.625% Convertible Senior Notes due in 2016 (the “2016 Notes”). The 2016 Notes mature on December 15, 2016, and bear interest at a rate of 1.625% per annum payable semi-annually in arrears on December 15 and June 15 of each year. The portion of the debt proceeds that was classified as equity at the time of the offering was $43.2 million, an equivalent of that amount is being amortized to interest expense using the effective interest method through December 2016. The effective interest rate implicit in the liability component is 5.6%.

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (continued)
At June 30, 2016, the carrying amount of the liability component was $223.0 million, the remaining unamortized discount was $4.1 million, the unamortized debt issuance cost was fully amortized and the principal amount outstanding was $227.1 million. At December 31, 2015, the carrying amount of the liability component was $218.2 million, the remaining unamortized discount was $8.4 million, the remaining unamortized debt issuance cost was $0.5 million and the principal amount outstanding was $227.1 million.
The fair value of the 2016 Notes at June 30, 2016 was approximately $343.2 million. The fair value of the liability of the 2016 Notes was determined using a discounted cash flow model based on current market interest rates available to the Company. These inputs are corroborated by observable market data for similar liabilities and therefore classified within Level 2 of the fair value hierarchy.
The 2016 Notes are senior, unsecured obligations of the Company, and are convertible into cash and, if applicable, shares of its common stock based on an initial conversion rate, subject to adjustment of 18.9287 shares per $1,000 principal amount of 2016 Notes (which represents an initial conversion price of approximately $52.83 per share). The Company will satisfy any conversion of the 2016 Notes with cash up to the principal amount of the 2016 Notes pursuant to the net share settlement mechanism set forth in the indenture and, with respect to any excess conversion value, with shares of the Company’s common stock. The 2016 Notes are convertible only in the following circumstances: (1) if the closing sale price of the Company’s common stock exceeds 150% of the conversion price during a period as defined in the indenture; (2) if the average trading price per $1,000 principal amount of the 2016 Notes is less than or equal to 98% of the average conversion value of the 2016 Notes during a period as defined in the indenture; (3) at any time on or after June 15, 2016; or (4) if specified corporate transactions occur, which included the spin-off of the spine business. The issue price of the 2016 Notes was equal to their face amount, which is also the amount holders are entitled to receive at maturity if the 2016 Notes are not converted. As of March 31, 2015, certain conversion features were triggered due to the announced spin-off of the Company's subsidiary, SeaSpine Holdings Corporation, which allowed the holders to convert all or any of the 2016 Notes subject to certain conditions. The 2016 Notes were convertible through June 10, 2015 and as of the close of the conversion window, note holders provided notice to convert 2,903 notes. During 2015, the Company paid $2.9 million in cash and issued 8,457 shares to settle the obligation to the note holders that converted. The Company considers the balance to be long-term in nature based on its current intent and ability to refinance the borrowing.
In connection with the issuance of the 2016 Notes, the Company entered into call transactions and warrant transactions, primarily with affiliates of the initial purchasers of such notes (the “hedge participants”). The initial strike price of the call transaction is approximately $52.83 per share, subject to customary anti-dilution adjustments. The initial strike price of the warrant transaction is approximately $64.43 per share, subject to customary anti-dilution adjustments.

Interest Rate Hedging
The Company’s interest rate risk relates to U.S. dollar denominated variable interest rate borrowings. On June 22, 2016, the Company entered into two $50.0 million interest rate swap derivative instruments with separate financial institutions, each with an effective date of December 31, 2016 to manage its earnings and cash flow exposure to changes in interest rates covering a portion of its floating-rate debt. These interest rate swaps expires on June 30, 2019.
On August 10, 2015 the interest rate swap derivative instrument the Company entered into on August 10, 2010 with an effective date of December 31, 2010 expired. The interest rate swap was used to manage the Company's earnings and cash flow exposure to changes in interest rates by converting a portion of its floating-rate debt into fixed-rate debt.
The Company designated these derivative instruments as cash flow hedges. The Company recorded the effective portion of any change in the fair value of a derivative instrument designated as a cash flow hedge as unrealized gains or losses in accumulated other comprehensive income (“AOCI”), net of tax, until the hedged item affected earnings, at which point the effective portion of any gain or loss was reclassified to earnings. If the hedged cash flow does not occur, or if it becomes probable that it will not occur, the Company will reclassify the amount of any gain or loss on the related cash flow hedge to interest expense at that time.
As of June 30, 2016, the Company had total outstanding interest rate swaps of $100.0 million each with an effective date of December 31, 2016.
Foreign Currency Hedging
From time to time the Company enters into foreign currency hedge contracts intended to protect the U.S. dollar value of certain forecasted foreign currency denominated transactions. The Company records the effective portion of any change in the fair value of foreign currency cash flow hedges in AOCI, net of tax, until the hedged item affects earnings. Once the related hedged item affects earnings, the Company reclassifies the effective portion of any related unrealized gain or loss on the foreign currency cash flow hedge to earnings. If the hedged forecasted transaction does not occur, or if it becomes probable that it will not occur, the Company will reclassify the amount of any gain or loss on the related cash flow hedge to earnings at that time.
The success of the Company’s hedging program depends, in part, on forecasts of certain activity denominated in euros. The Company may experience unanticipated currency exchange gains or losses to the extent that there are differences between forecasted and actual activity during periods of currency volatility. In addition, changes in currency exchange rates related to any unhedged transactions may affect its earnings and cash flows.
Counterparty Credit Risk
The Company manages its concentration of counterparty credit risk on its derivative instruments by limiting acceptable counterparties to a group of major financial institutions with investment grade credit ratings, and by actively monitoring their credit ratings and outstanding positions on an ongoing basis. Therefore, the Company considers the credit risk of the counterparties to be low. Furthermore, none of the Company’s derivative transactions are subject to collateral or other security arrangements, and none contain provisions that depend upon the Company’s credit ratings from any credit rating agency.
Fair Value of Derivative Instruments
The Company has classified all of its derivative instruments within Level 2 of the fair value hierarchy because observable inputs are available for substantially the full term of the derivative instruments. The fair value of the foreign currency forward exchange contracts related to inventory purchases is determined by comparing the forward rate as of the period end and the settlement rate specified in each contract. The fair value of the interest rate swaps was developed using a market approach based on publicly available market yield curves and the terms of the related swap. The Company performs ongoing assessments of counterparty credit risk.

8. STOCK-BASED COMPENSATION
As of June 30, 2016, the Company had stock options, restricted stock awards, performance stock units, contract stock awards and restricted stock unit awards outstanding under three plans, the 2000 Equity Incentive Plan (the “2000 Plan”), the 2001 Equity Incentive Plan (the “2001 Plan”), and the 2003 Equity Incentive Plan (the “2003 Plan,” and collectively, the “Plans”).
Stock options issued under the Plans become exercisable over specified periods, generally within four years from the date of grant for officers, directors, and employees, and generally expire eight years from the grant date for employees, and from eight to ten years for directors and certain executive officers. Restricted stock issued under the Plans vests over specified periods, generally three years after the date of grant. The vesting of performance stock, issued under the Plans, is subject to service and performance conditions.
In connection with the separation of SeaSpine on July 1, 2015 and in accordance with the Employee Matters Agreement, the Company made certain adjustments to the exercise price and number of share-based compensation awards with the intention of preserving the intrinsic value of the awards prior to the separation. Stock options issued in 2015 prior to the separation converted to those of the entity where the employee is working post-separation. Stock options issued prior to 2015 converted to both Integra and SeaSpine options such that the holders received stock options in both companies. The exercise price of these outstanding awards was adjusted to preserve the value of the awards immediately prior to the separation. Performance stock, restricted stock, and contract stock were adjusted to provide holders performance stock, restricted stock, and contract stock in the company that employs such employee following the separation. The adjustments to the Company's stock-based compensation awards resulted in an increase in incremental fair value of $4.4 million, of which $3.3 million has been previously recorded and $0.2 million and $0.4 million were recorded in the three and six months ended June 30, 2016. The remaining $0.7 million will be recognized prospectively over the remaining term of outstanding awards, adjusted, as applicable, for forfeitures.
Stock Options
As of June 30, 2016, there were approximately $4.0 million of total unrecognized compensation costs related to unvested stock options, including the additional incremental fair value expense discussed above. These costs are expected to be recognized over a weighted-average period of approximately two years. There were 111,662 stock options granted during the six months ended June 30, 2016.
Awards of Restricted Stock, Performance Stock and Contract Stock
Performance stock, restricted stock and contract stock awards generally have requisite service periods of three years. Performance stock units are subject to graded vesting conditions, and the Company expenses their fair value over the requisite service period. The Company expenses the fair value of restricted stock and contract stock awards on a straight-line basis over the vesting period or requisite service period, whichever is shorter. As of June 30, 2016, there were approximately $22.2 million of total unrecognized compensation costs related to these unvested awards, including the additional incremental fair value expense discussed above. The Company expects to recognize these costs over a weighted-average period of approximately two years. The Company granted 155,371 restricted stock awards/stock units and 78,177 performance shares during the six months ended June 30, 2016.
The Company has no formal policy related to the repurchase of shares for the purpose of satisfying stock-based compensation obligations.
The Company also maintains an Employee Stock Purchase Plan (the “ESPP”), which provides eligible employees with the opportunity to acquire shares of common stock at periodic intervals by means of accumulated payroll deductions. The ESPP is a non-compensatory plan based on its terms.
9. TREASURY STOCK
On October 28, 2014, the Board of Directors authorized a repurchase plan of up to $75.0 million of its outstanding common stock through December 2016. As of June 30, 2016, there remained $75.0 million available for repurchases under this authorization.
There were no cash treasury stock repurchases during the six months ended June 30, 2016 and 2015.

10. INCOME TAXES
The following table provides a summary of the Company’s effective tax rate:

| Three Months Ended June 30, |  | Six Months Ended June 30,

Reported tax rate | 14.6 | % |  | 33.3 | % |  | 12.6 | % |  | 33.6 | %

The Company’s effective income tax rates for the three months ended June 30, 2016 and 2015 were 14.6% and 33.3%, respectively. In the three months ended June 30, 2016, the primary drivers of the lower tax rate are excess tax benefits of $1.2 million as a result of early adoption of ASU 2016-09 and a $0.2 million benefit included for the release of uncertain tax positions. The primary driver of the higher tax rate for the three months ended June 30, 2015, compared to the three months ended June 30, 2016, was $0.4 million expense relating to foreign tax returns filed during the three months ended June 30, 2015 and jurisdiction mix of income earned.
The Company's effective income tax rates for the six months ended June 30, 2016 and 2015 were 12.6% and 33.6%, respectively. In the six months ended June 30, 2016, the primary drivers of the lower tax rate are excess tax benefits of $3.0 million as a result of early adoption of ASU 2016-09 and a $0.5 million benefit included for the release of uncertain tax positions. The primary drivers of the higher income tax rate for the six months ended June 30, 2015, compared to the six months ended June 30, 2016, are the $0.6 million expense and $0.4 million expense related to transfer pricing recorded and foreign tax returns filed for the six months ended June 30, 2015, respectively, and jurisdiction mix of income earned.
The Company expects its effective income tax rate for the full year to be approximately 20.3%, resulting largely from the release of uncertain tax positions and jurisdiction mix of pre-tax income in U.S.-based operations relative to foreign operations. This estimate could be revised in the future as additional information is presented to the Company.

In connection with the separation of SeaSpine on July 1, 2015 and in accordance with the Employee Matters Agreement the Company made certain adjustments to the exercise price and number of share-based compensation awards with the intention of preserving the intrinsic value of the awards prior to the separation. Stock options issued in 2015 prior to the separation converted to those of the entity where the employee is working post-separation. Stock options issued prior to 2015 converted to both Integra and SeaSpine options such that the holders received stock options in both companies. The exercise price of these outstanding awards was adjusted to preserve the value of the awards immediately prior to the separation. Performance stock, restricted stock, and contract stock were adjusted to provide holders performance stock, restricted stock, and contract stock in the company that employs such employee following the separation.
Common stock of approximately 0.2 million and 0.1 million of shares at June 30, 2016 and 2015, respectively, that are issuable through exercise or conversion of dilutive securities were not included in the computation of diluted net income per share because their effect, would have been antidilutive.
For the three and six months ended June 30, 2016 and 2015, the potential excess conversion value on the 2016 Notes and warrants were included in the Company's dilutive share calculation because the average stock price for the three and six months ended June 30, 2016 and 2015 exceeded the conversion price.

14. COMMITMENTS AND CONTINGENCIES
In consideration for certain technology, manufacturing, distribution, and selling rights and licenses granted to the Company, the Company has agreed to pay royalties on sales of certain products that it sells. The royalty payments that the Company made under these agreements were not significant for any of the periods presented.
The Company is subject to various claims, lawsuits and proceedings in the ordinary course of the Company's business, including claims by current or former employees, distributors and competitors and with respect to its products and product liability claims, lawsuits and proceedings, some of which have been settled by the Company. In the opinion of management, such claims are either adequately covered by insurance or otherwise indemnified, or are not expected, individually or in the aggregate, to result in a material adverse effect on our financial condition. However, it is possible that the Company's results of operations, financial position and cash flows in a particular period could be materially affected by these contingencies.
TEI, acquired by Integra on July 17, 2015, manufactures a bovine-derived surgical mesh product for Boston Scientific Corporation ("BSC") and has been named as a defendant in lawsuits under a broad range of products liability theories, many of which have not been served on TEI. Currently, there are approximately fifty active cases against TEI. Pursuant to an indemnification agreement with BSC (i) BSC is managing the litigation; (ii) TEI has in place a products liability insurance policy, of which it must exhaust $3.0 million before BSC’s indemnity begins to cover relevant claims (and of which only a small portion has been utilized to date and against which the insurer has reserved the entire $3.0 million). Because the thrust of products liability litigation focuses on synthetic surgical mesh products, counsel is filing motions to dismiss on behalf of TEI in many cases. In addition, Integra has certain protections in the merger agreements with TEI which would indemnify it for approximately $30.0 million for the first fifteen months after closing and between $20.0 and $30.0 million for the remainder of the three-year period after closing for losses

relating to a variety of matters, including half of certain products liability claims (including those related to the product it manufactures for BSC) not covered by insurance.
The Company accrues for loss contingencies when it is deemed probable that a loss has been incurred and that loss is estimable. The amounts accrued are based on the full amount of the estimated loss before considering insurance proceeds, and do not include an estimate for legal fees expected to be incurred in connection with the loss contingency. The Company consistently accrues legal fees expected to be incurred in connection with loss contingencies as those fees are incurred by outside counsel as a period cost.
Contingent Consideration
The Company increased the fair value of contingent consideration during the six-month period ended June 30, 2016 to reflect the change in the time value of money during the period. A reconciliation of the opening balances to the closing balances of these Level 3 measurements is as follows (in thousands):

|  | Location in Statement of Operations
Balance as of January 1, 2016 | $ | 21,831 |  |
Loss from increase in fair value of contingent consideration liabilities | 251 |  | Selling, general and administrative
Fair value at June 30, 2016 | $ | 22,082 |  |

The fair values of contingent consideration were estimated using a discounted cash flow model using discount rate of 2.20%. The Company assesses these assumptions on an ongoing basis as additional information impacting the assumptions is obtained. The entire contingent consideration balance was included in Other liabilities at June 30, 2016 and December 31, 2015.
15. SUBSEQUENT EVENT
On July 12, 2016, the Company entered into an additional $50.0 million interest rate swap derivative instruments with an effective date of December 31, 2016 to manage its earnings and cash flow exposure to changes in interest rates covering a portion of its floating-rate debt. This interest rate swap expires on June 30, 2019.
ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Table of Contents
Technologies products are sold through directly employed sales representatives and specialty distributors focused on their respective surgical specialties. We sell in the international markets through a combination of direct sales organizations and distributors.
We also market certain products through strategic partners in the United States.
Our objective is to become a multi-billion dollar diversified global medical technology company that helps patients by limiting uncertainty for medical professionals, and is a high-quality investment for shareholders. We will achieve these goals by delivering on our Brand Promises to our customers so they can concentrate on providing the best care for their patients and by becoming a company recognized as a leader by our customers worldwide in specialty surgical applications, regenerative technologies and extremities orthopedics. Our strategy is built around three pillars - execute, optimize, and accelerate growth. These three pillars support our strategic initiatives to deliver on our commitments through improved planning and communication, optimize our infrastructure, and grow by introducing new products to the market through internal development, geographic expansion, and strategic acquisitions.
We aim to achieve growth in our revenues while maintaining strong financial results. While we pay attention to any meaningful trend in our financial results, we pay particular attention to measurements that are indicative of long-term profitable growth. These measurements include (1) revenue growth (including organic growth and through acquisitions), (2) gross margins on total revenues, (3) operating margins (which we aim to continually expand as we leverage our existing infrastructure), (4) earnings before interest, taxes, depreciation, and amortization, and (5) earnings per diluted share of common stock.
We believe that we are particularly effective in the following aspects of our business:

• | Regenerative Technology Platform. We have developed numerous product lines through our proprietary collagen and polyethylene glycol technologies that are sold through all of our sales channels.

• | Diversification and Platform Synergies. The Specialty Surgical Solutions and Orthopedics and Tissue Technologies selling platforms each contribute a different strength to our core business. Specialty Surgical Solutions has a strong presence in the hospital, with market-leading products and comprehensive solutions for surgical specialties, such as neurosurgery, as well as a strong capacity to generate cash flows. Orthopedics and Tissue Technologies enables us to grow our top line by continuing to introduce new, differentiated products in fast-growing markets, such as joint replacement, plastic and reconstruction and advanced wound care, as well as to increase gross margins. We have unique synergies between these platforms, such as our regenerative technology, instrument sourcing capabilities, and enterprise contract management.

• | Specialized Sales Footprint. Our medical technology investment and manufacturing strategy provide us with a specialized set of customer call-points and synergies. We have market-leading products across our portfolios that provide both scale and depth in solutions for a broad set of clinical needs. We also have clinical expertise across all of our channels in the United States, and an opportunity to expand and leverage this expertise in markets worldwide. Many of our customers are facing pressure placed upon them by healthcare reform worldwide. In response to our customers’ needs for clinical and technical solutions across multiple departments and clinical areas, we have developed and deployed our Enterprise Selling initiative to bring unique clinical solutions to even the most difficult healthcare issues in key accounts across multiple sites and multi-hospital integrated delivery networks.

• | Ability to Change and Adapt. Our corporate culture is what enables us to adapt and evolve. We have demonstrated that we can quickly and profitably integrate new products and businesses. This core strength has made it possible for us to grow over the years, and is key to our ability to grow into a multi-billion dollar company.

Acquisitions
Tekmed
On December 15, 2015, the Company acquired the assets of Tekmed Instruments S.p.A ("Tekmed") for an aggregate purchase price of $14.1 million. Tekmed was a distributor of the Company's products in Italy and has a specialty focus on neurosurgery and neurotrauma, along with representation in plastic and reconstructive surgery, cardiovascular surgery, image diagnostics, general surgery, anesthesia and intensive care, interventional radiology, and proton therapy. This acquisition enables the Company to support Specialty Surgical Solutions growth in Italy along with other key Integra franchises.
Tornier's United States Toe & Ankle Business
On October 2, 2015, the Company acquired the United States rights to Tornier's Salto Talaris® and Salto Talaris® XT ankle replacement products and Tornier's Futura TM silastic toe replacement products (the "Salto and Futura") for $6.0 million in cash. The estimated fair value of the net assets acquired exceeded the purchase price for the Salto and Futura product lines and resulted in the Company recording a gain of $1.1 million for the year-ended December 31, 2015 in Other Income. The acquired toe and ankle products enhance the Company's lower extremities product offering and accelerates its entry into the U.S. total ankle replacement market.

TEI Biosciences, Inc. and TEI Medical, Inc.
In July 2015, we executed the two merger agreements (collectively, the "Agreements") under which we acquired TEI Biosciences, Inc., a Delaware corporation ("TEI Bio"), and TEI Medical Inc., a Delaware corporation ("TEI Med"). Under the terms of the Agreements, we paid $312.2 million ($210.9 million for TEI Bio and $101.3 million for TEI Med) including working capital and purchase price adjustment of $0.2 million ($0.5 million for TEI Bio offset by $0.7 million cash received for TEI Med) which was recorded as a reduction from goodwill. The purchase price consists of a cash payment to the former shareholders of TEI Bio and TEI Med of approximately $312.4 million upon the closing of the transaction, net of $1.2 million of acquired cash.
TEI Bio is in the business of developing and commercializing biologic devices for soft tissue repair and regenerative applications, including dura and hernia repair and plastic and reconstructive surgery. TEI Med holds a license to TEI Bio’s regenerative technology in the fields of wound healing and orthopedics.
Clinical and Product Development Activities
During July 2014, we completed our multi-center clinical trial evaluating the safety and effectiveness of the INTEGRA® Dermal Regeneration Template for the Treatment of Diabetic Foot Ulcers (“DFU”). The data collected formed the foundation for the Premarket Approval ("PMA") Supplement application that we filed with the FDA. The FDA approved the PMA on January 7, 2016, and the Company commenced commercialization of the resulting DFU product, Omnigraft TM, in May 2016. We are also investing in next generation nerve products, additional clinical studies for indications to support existing products, and longer term research programs to evaluate combination products.
Separation of the Spine Business
In November 2014, we announced a plan to spin off our spine business into a stand-alone public company ("SeaSpine"). On July 1, 2015, we completed the distribution of 100% of the outstanding common shares of SeaSpine to Integra's stockholders, who received one share of SeaSpine common stock for every three shares of Integra held as of the close of business on the record date, June 19, 2015. We incurred separation expenses of approximately $10.0 million and $14.8 million in the three and six months ended June 30, 2015. Separation costs includes all incremental expenses that we incurred in order to effect the separation and the cost of all new employees recruited to operate the two separate companies. The separation costs through June 30, 2015 are reported within the discontinued operations.
Unless indicated otherwise, the information in the management discussion and analysis of financial condition and results of operations relates to the Company’s continuing operations. Further information regarding the SeaSpine separation and discontinued operations reporting may be found in Note 2 - Discontinued Operations.
RESULTS OF OPERATIONS
Executive Summary
Net income for the three months ended June 30, 2016, was $12.8 million, or $0.32 per diluted share as compared to $12.0 million or $0.35 per diluted share for the three months ended June 30, 2015.
Net income for the six months ended June 30, 2016, was $26.2 million, or $0.68 per diluted share as compared to $23.8 million or $0.71 per diluted share for the six months ended June 30, 2015.
Net income for the six months ended June 30, 2016 increased from the same period last year primarily as a result of increased revenues partially offset by investments in our growing sales channel and research and development. The operations reflect full inclusion of the Tekmed, Tornier's U.S. Foot and Ankle, and TEI activities as well as strong growth in our dural repair and regenerative technology franchises.

Total from continuing operations | $ | 16,275 |  |  | $ | 12,723 |  |  | $ | 30,063 |  |  | $ | 24,254 |

We typically define special charges as items for which the amounts and/or timing of such expenses may vary significantly from period to period, depending upon our acquisition, integration and restructuring activities, and for which the amounts are non-cash in nature, or for which the amounts are not expected to recur at the same magnitude. We believe that given our ongoing strategy of seeking acquisitions, our continuing focus on rationalizing our existing manufacturing and distribution infrastructure and our continuing review of various product lines in relation to our current business strategy, certain of the special charges discussed above could recur with similar materiality in the future. We are engaged in a multi-year implementation of a new global enterprise resource planning ("ERP") system to improve our operational efficiency and have made progress in implementing the ERP across multiple sites. We expect the additional capital and integration expense associated with our ERP system to be completed over the next year.
We believe that the separate identification of these special charges provides important supplemental information to investors regarding financial and business trends relating to our financial condition and results of operations. Investors may find this information useful in comparing our operating performance from period to period, assessing the business model objectives that management has established, and comparing our results against those of other companies in our industry. We provide this information to investors so that they can analyze our operating results in the same way that management does and to use this information in their assessment of our core business and valuation of Integra.
Update on Remediation Activities
We have an outstanding FDA warning letter related to TEI, acquired by Integra on July 17, 2015. TEI received a Warning Letter from the FDA dated May 29, 2015 for promoting the product SurgiMend for breast surgery applications that were not cleared in the 510(k) process and do not have a PMA Approval for the indication. The FDA requested that TEI immediately cease all activities that resulted in misbranding or adulteration of the product in commercial distribution. The FDA also required TEI to cease all violations regarding promotion of the product for an indication that was not cleared or approved. TEI responded with a corrective action plan to the FDA and took action to address the issues prior to the completion of the acquisition. We will continue to monitor this activity and address all corrective actions submitted to the FDA. The FDA may not accept our corrective action plan or it may choose to scrutinize other promotional claims on products and require additional corrective actions. We do not expect to incur material operating expenses to complete the corrective action plan.
There were no material remediation expenses incurred in the three and six months ended June 30, 2016.

Three Months Ended June 30, 2016 as Compared to Three Months Ended June 30, 2015
Revenues and Gross Margin
For the three months ended June 30, 2016 total revenues increased by $36.6 million to $249.3 million from $212.7 million for the same period in 2015.
Specialty Surgical Solutions revenues were $158.2 million, an increase of 7.8% from the prior-year period. The increase resulted from the growth in all of our major franchises, led by our dural repair products, which increased in the mid double digits for the quarter and precision tools and instruments which increased mid-single digits. This increase is above the market growth rate driven by new product introductions.
Orthopedics and Tissue Technologies revenues were $91.1 million, an increase of 38.2% from the prior-year period. The increase resulted from the impact of TEI, Salto and Futura product sales arising out of the acquisitions which added $15.8 million in the quarter. Non-acquired product growth was led by strong demand and market adoption in our regenerative products, which comprise over 70% of sales in this segment, driven by success from commercial and channel investments, as well as increased end user market demand in certain parts of our private label business.
Gross margin increased to $159.7 million for the three-month period ended June 30, 2016, up from $137.4 million for the same period last year. Gross margin as a percentage of total revenue decreased to 64.1% for the second quarter of 2016 from 64.6% for the same period last year. The decline in gross margin percentage resulted from an increase in inventory step-up charges and intangible assets amortization resulting from the TEI, Salto and Futura acquisitions, and start-up cost of our collagen manufacturing center. An increase in sales of higher margin products such as Dural Repair, skin and wound products, and improvements in the utilization of our manufacturing facilities, helped offset that slight decline.
We expect our consolidated gross margin percentage for the full year 2016 to be approximately 64.5% to 65.0%. We expect the increase in gross margin to occur because of the full-year contribution from TEI and continued favorable product mix, which will more than offset the costs associated with operating our new collagen manufacturing center.
Operating Expenses
The following is a summary of operating expenses as a percent of total revenues:

| Three Months Ended June 30,
| 2016 |  | 2015
Research and development | 5.9 | % |  | 5.6 | %
Selling, general and administrative | 47.8 | % |  | 46.7 | %
Intangible asset amortization | 1.4 | % |  | 0.8 | %
Total operating expenses | 55.1 | % |  | 53.1 | %

Total operating expenses, which consist of research and development expenses, selling, general and administrative expenses, and amortization expense, increased $24.3 million, or 21.5%, to $137.4 million in the three months ended June 30, 2016, compared to $113.1 million in the same period last year.
27

Table of Contents
Research and development expenses in the second quarter of 2016 increased compared to the same period last year. This increase primarily resulted from additional spending on new product development and clinical studies. We expect full-year 2016 spending on research and development to be between 5.5% and 6.0% of total revenues.
Selling, general and administrative expenses in the second quarter of 2016 increased by $19.9 million to $119.2 million compared to $99.3 million in the same period last year. Selling and marketing expenses increased by $19.0 million, resulting from higher headcount in our sales force compared to last year resulting primarily from the TEI acquisition, and additional investments in adding direct sales representatives and distributors. General and administrative costs increased by $0.9 million, resulting from increases in ongoing projects, employee compensation, and benefit plans offset by the elimination of the Medical Device Excise Tax expense, which was $2.5 million in the second quarter of 2015. We expect full year selling, general and administrative expenses to be between 45.5% and 46.0% of revenue in 2016, as we make additional investments in our commercial channels as a result of the benefit of the Medical Device Excise Tax suspension.
Amortization expense as a percentage of revenues in the second quarter of 2016 increased compared to the same period last year. This was primarily related to the increase in intangibles from the three acquisitions in the second half of 2015.
Non-Operating Income and Expenses

Interest expense | (6,588 | ) |  | (5,485 | )
Other income (expense), net | (852 | ) |  | (860 | )

Interest Income and Interest Expense
Interest expense in the three months ended June 30, 2016 increased by $1.1 million, primarily due to increased borrowings and higher effective borrowing rates on our Senior Credit Facility compared to the prior year. Our reported interest expense for the three-month periods ended June 30, 2016 and 2015 includes non-cash interest related to the accounting for convertible securities of $2.1 million and $1.9 million, respectively.
Interest income was negligible for the three months ended June 30, 2016 and 2015.
Other Income (Expenses)
Other income (expense) for the three months ended June 30, 2016 includes $1.1 million loss on disposal of property and equipment. Other income for the three months ended June 30, 2016 and 2015 also includes the impact of transactional foreign exchange gains and losses.

The Company’s effective income tax rates for the three months ended June 30, 2016 and 2015 were 14.6% and 33.3%, respectively. In the three months ended June 30, 2016, the primary drivers of the lower tax rate are excess tax benefits of $1.2 million as a result of early adoption of ASU 2016-09 and a $0.2 million benefit included for the release of uncertain tax positions. The primary driver of the higher tax rate for the three months ended June 30, 2015, compared to the three months ended June 30, 2016, was the $0.4 million expenses relating to foreign tax returns filed during the three months ended June 30, 2015 and jurisdiction mix of income earned.
28

Table of Contents
The Company expects its effective income tax rate for the full year to be approximately 20.3%, resulting largely from the release of uncertain tax positions and the jurisdictional mix of pretax income in U.S.-based operations relative to foreign operations. This estimate could be revised in the future as additional information is presented to the Company.
The effective tax rate may vary from period to period depending on, among other factors, the geographic and business mix of taxable earnings and losses, tax planning and settlements with various taxing authorities. We consider these factors and others, including our history of generating taxable earnings, in assessing our ability to realize tax assets on a quarterly basis.
While it is often difficult to predict the final outcome or the timing of resolution of any particular matter with the various Federal, state, and foreign tax authorities, we believe that our reserves reflect the most probable outcome of known tax contingencies. Settlement of any particular issue would usually require the use of cash. Favorable resolution would be recognized as a reduction to our annual effective tax rate in the year of resolution. The tax reserves are presented in the balance sheet within other liabilities, except for amounts relating to items we expect to pay in the coming year, which would be classified as current income taxes payable.
Six Months Ended June 30, 2016 as Compared to Six Months Ended June 30, 2015
Revenues and Gross Margin
For the six months ended June 30, 2016, total revenues increased by $70.9 million to $486.1 million from $415.2 million during the prior-year period.
Specialty Surgical Solutions revenues were $309.3 million, an increase of 7.9% from the prior-year period. Our dural repair franchise performed very well as demand for our products continued to rise. Revenue in our Precision Tools and Instruments business, which includes the former Instruments product portfolio as well as our cranial stabilization and stereotaxy product lines, also increased in part due to new product introductions. Neuro critical care revenues remained relatively flat year over year.
Orthopedics and Tissue Technologies revenues were $176.7 million, an increase of 37.6% from the prior-year period. The increase partially resulted from the impact of the TEI, Salto and Futura product sales arising out of the acquisitions, which added $33.2 million for the six months ended June 30, 2016. The increase was also driven by strong demand in our regenerative technologies franchise as a result of additional headcount in our sales force, a steady increase in market adoption of regenerative products and end user demand in certain parts of our private label business. Excluding acquisitions, our extremity franchises were relatively flat.
Gross margin increased to $311.7 million for the six-month period ended June 30, 2016 from $264.7 million for the same period last year. Gross margin as a percentage of total revenue increased to 64.1% for the year to date period from 63.8% for the same period last year. The increase in gross margin percentage resulted primarily from an increase in sales of higher margin products such as DuraSeal, DuraGen, skin and wound products.
Operating Expenses

Table of Contents
Selling, general and administrative expenses in the first six months of 2016 increased by $38.6 million to $231.2 million compared to $192.6 million in the same period last year. Selling and marketing expenses increased by $37.7 million, primarily resulting from higher commissions and TEI acquisition-related expenses, including the addition of sales representatives. General and administrative costs increased $0.9 million resulting from increase in ongoing projects, employee compensation, and benefit plan mostly offset by elimination of the Medical Device Excise Tax expense of $4.5 million for the six months period ended June 30, 2015. In addition, we experienced higher incentive compensation costs for our sales forces for the six months period ended June 30, 2016.
Amortization expense in the first six months of 2016 increased by $3.5 million to $6.9 million, compared to $3.5 million in the same period last year. Amortization expense in the first six months of 2016 reflects the increase in intangibles due to the three acquisitions in the second half of 2015.

We generate significant revenues outside the United States, a portion of which are U.S. dollar-denominated transactions conducted with customers who generate revenue in currencies other than the U.S. dollar. As a result, currency fluctuations between the U.S. dollar and the currencies in which those customers do business could have an impact on the demand for our products in foreign countries. Local economic conditions, regulatory compliance or political considerations, the effectiveness of our sales representatives and distributors, local competition and changes in local medical practice all may combine to affect our sales into markets outside the United States.
Domestic revenues increased to $191.9 million, or 77.0% of total revenues, for the three months ended June 30, 2016 from $162.5 million, or 76.4% of total revenues, for the three months ended June 30, 2015. International revenues increased to $57.4 million from $50.2 million in the prior-year period, an increase of 14.5%.
Domestic revenues increased to $373.1 million, or 76.8% of total revenues, for the six months ended June 30, 2016 from $315.3 million, or 75.9% of total revenues, for the six months ended June 30, 2015. International revenues increased to $113.0 million from $99.9 million in the prior-year period, an increase of 13.0%.
LIQUIDITY AND CAPITAL RESOURCES
Cash and Marketable Securities
We had cash and cash equivalents totaling approximately $86.8 million and $48.1 million at June 30, 2016 and December 31, 2015, respectively, which are valued based on Level 1 measurements in the fair value hierarchy. At June 30, 2016, our non-U.S. subsidiaries held approximately $58.1 million of cash and cash equivalents that are available for use by our operations outside of the United States. If cash and cash equivalents held by our non-U.S. subsidiaries were repatriated to the United States, or used for United States operations, certain amounts could be subject to tax in the United States for the incremental amount in excess of the foreign tax paid.

| 2016 |  | 2015
| (In thousands)
Net cash provided by operating activities | $ | 63,109 |  |  | $ | 71,812 |
Net cash used in investing activities | (14,773 | ) |  | (11,684 | )
Net cash (used in) provided by financing activities | (9,082 | ) |  | 20,590 |
Effect of exchange rate fluctuations on cash | (583 | ) |  | (2,146 | )

In 2016, we anticipate that our principal uses of cash will include approximately $40.0 million of capital expenditures primarily for support and maintenance in our existing plants for facility automation, our enterprise resource planning system implementation, and additions to our instrument kits used in sales of orthopedic products.
Cash Flows Provided by Operating Activities
We generated operating cash flows of $63.1 million and $71.8 million for the six months ended June 30, 2016 and 2015, respectively.
Operating cash flows for the six months ended June 30, 2016 decreased compared to the same period in 2015. Net income increased compared to the same period of the prior year. Changes in non-cash adjustments included in net income increased cash flows for the six months ended June 30, 2016 by approximately $13.9 million compared to the same period in 2015, which resulted primarily from the increase in depreciation and amortization. Changes in working capital decreased cash flows for the six months ended June 30, 2016 by approximately $11.8 million. Among the changes in working capital, accounts receivable used $13.5 million of cash, inventory used $7.4 million of cash, prepaid expenses and other current assets provided $4.4 million of cash and accounts payable, and accrued expenses and other current liabilities provided $2.2 million of cash. Increases in accounts receivables and inventories are consistent with increase in revenue.
Operating cash flow for the six months ended June 30, 2015 benefited from an increase in net income of $16.9 million compared to the same period in 2014. Changes in working capital increased cash flows by approximately $12.7 million. Among the changes in working capital, accounts receivable used $5.2 million of cash, inventory used $6.1 million of cash, prepaid expenses and other current assets provided $0.9 million of cash and accounts payable, accrued expenses and other current liabilities provided $24.0 million of cash.
Cash Flows Used in Investing Activities

During the six months ended June 30, 2015, we received cash of $1.4 million related to the sale of our Andover, U.K. facility and $1.8 million related to a working capital adjustment from the MicroFrance acquisition. We also paid $15.0 million for capital expenditures, most of which was directed to the expansion of our new collagen manufacturing center and global enterprise system implementation.
Cash Flows (Used in) Provided by Financing Activities
Our principal source of cash from financing activities in the six months ended June 30, 2016 was a $15.0 million borrowing under our Senior Credit Facility for general operating purposes and proceeds we received from stock option exercises of $9.3 million. Additionally, we made a repayment of $28.8 million on the revolving portion of our Senior Credit Facility.
Our principal use of cash for financing activities in the six months ended June 30, 2015 was a repayment of $15.0 million on the revolving portion under our Senior Credit Facility. Additionally, we received proceeds related to stock option exercises of $7.3 million and borrowed $35.0 million under our Senior Credit Facility to fund SeaSpine in conjunction in the spin-off.
Working Capital
At June 30, 2016 and December 31, 2015, working capital was $344.2 million and $299.4 million, respectively. Working capital is defined as net of total current assets less total current liabilities.

Upcoming Debt Maturities
The Company’s 1.625% senior convertible notes mature in 2016. The Company considers the balance to be long term in nature based on its current intent and ability to refinance the borrowing prior to its maturity. The Company may attempt to refinance, extend, or use available borrowing capacity under the Senior Credit Facility to settle this obligation, depending on prevailing market conditions. Our ability to refinance or extend this obligation will depend on our operating and financial performance, which in turn is subject to prevailing economic conditions and financial, business and other factors beyond our control. Any disruptions in our operations, the financial markets, or overall economy may adversely affect the availability and cost of credit to us.
Amended and Restated Senior Credit Agreement, Convertible Debt and Related Hedging Activities
See Note 6 - Debt to the current period’s condensed consolidated financial statements for a discussion of our (i) amended and restated Senior Credit Agreement, and (ii) convertible debt and related hedging activities.
Share Repurchase Plan
On October 28, 2014, our Board of Directors authorized a repurchase plan of up to $75.0 million of outstanding common stock through December 2016. Shares may be repurchased either in the open market or in privately negotiated transactions. There were no shares repurchased under this program through June 30, 2016 and $75.0 million remains available under the authorization.
Dividend Policy
We have not paid any cash dividends on our common stock since our formation. Our Senior Credit Facility limits the amount of dividends that we may pay. Any future determinations to pay cash dividends on our common stock will be at the discretion of our Board of Directors and will depend upon our financial condition, results of operations, cash flows and other factors deemed relevant by the Board of Directors.
Capital Resources
We believe that our cash and available borrowings under the Senior Credit Facility are sufficient to finance our operations and capital expenditures. The Company considers all such outstanding amounts to be long term in nature based on its current intent and ability to repay the borrowings outside of the next twelve-month period.

(1 | ) | The estimated debt service obligation of the senior convertible securities includes interest expense representing the amortization of the discount on the liability component of the senior convertible notes in accordance with the authoritative guidance. See Note 6 - Debt of our condensed consolidated financial statements for additional information.
(2 | ) | The Company may borrow and make payments against the revolving credit portion of its Senior Credit Facility from time to time and considers all of the outstanding amounts to be long term based on its current intent and ability to repay the borrowing outside of the next twelve-month period.
(3 | ) | Interest is calculated on the term loan portion of the Senior Credit Facility and convertible securities based on current interest rates paid by the Company. As the revolving credit facility can be repaid at any time, no interest has been included in the calculation.
(4 | ) | Amounts shown under Employment Agreements do not include compensation resulting from a change in control.

The Company has excluded contingent consideration obligations related to prior acquisitions from the contractual obligations table above; these liabilities had a fair value of $22.1 million at June 30, 2016. These liabilities have been excluded because the amounts to be paid and the potential payment dates are not fixed.
The Company has also excluded the liability for uncertain tax benefits from the contractual obligations table above, including interest and penalties, totaling $0.6 million at June 30, 2016. This liability for uncertain tax benefits has been excluded because we cannot make a reliable estimate of the period in which the uncertain tax benefits may be realized.
Off-Balance Sheet Arrangements
There were no off-balance sheet arrangements during the six months ended June 30, 2016 that have or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to our interests.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to various market risks, including changes in foreign currency exchange rates and interest rates that could adversely affect our results of operations and financial condition. To manage the volatility relating to these typical business exposures, we may enter into various derivative transactions when appropriate. We do not hold or issue derivative instruments for trading or other speculative purposes.
Foreign Currency Exchange and Other Rate Risks
We operate on a global basis and are exposed to the risk that changes in foreign currency exchange rates could adversely affect our financial condition, results of operations and cash flows. We are primarily exposed to foreign currency exchange rate risk with respect to transactions and net assets denominated in euros, British pounds, Swiss francs, Canadian dollars, Japanese yen, Australian dollars and Chinese yuan. We manage the foreign currency exposure centrally, on a combined basis, which allows us to net exposures and to take advantage of any natural offsets. To mitigate the impact of currency fluctuations on transactions denominated in nonfunctional currencies, we periodically enter into derivative financial instruments in the form of foreign currency exchange forward contracts with major financial institutions. We temporarily record realized and unrealized gains and losses on these contracts that qualify as cash flow hedges in other comprehensive income, and then recognize them in other income or expense when the hedged item affects net earnings.
From time to time, we enter into foreign currency forward exchange contracts with terms of up to 12 months to manage currency exposures for transactions denominated in a currency other than an entity’s functional currency. As a result, the impact of foreign currency gains/losses recognized in earnings are partially offset by gains/losses on the related foreign currency forward exchange contracts in the same reporting period.
We maintain written policies and procedures governing our risk management activities. With respect to cash flow hedges, changes in cash flows attributable to hedged transactions are generally expected to be completely offset by changes in the fair value of hedge instruments. Consequently, foreign currency exchange contracts would not subject us to material risk due to exchange rate movements, because gains and losses on these contracts offset gains and losses on the assets, liabilities or transactions being hedged.
The results of operations discussed herein have not been materially affected by inflation.
Interest Rate Risk
Cash and Cash Equivalents - We are exposed to the risk of interest rate fluctuations on the interest income earned on our cash and cash equivalents. A hypothetical 100 basis point movement in interest rates applicable to our cash and cash equivalents outstanding at June 30, 2016 would increase interest income by approximately $0.9 million on an annual basis. No significant decrease in interest income would be expected as our cash balances are earning interest at rates of approximately one basis point. We are subject to foreign currency exchange risk with respect to cash balances maintained in foreign currencies.
Senior Credit Facility - Our interest rate risk relates primarily to U.S. dollar LIBOR-indexed borrowings. We have used an interest rate derivative instrument to manage our earnings and cash flow exposure to changes in interest rates. This interest rate swap fixes the interest rate on a portion of our expected LIBOR-indexed floating-rate borrowings beginning on December 31, 2016.
Based on our outstanding borrowings at June 30, 2016, a one-percentage point increase in interest rates would have affected interest expense on the debt by $3.8 million on an annualized basis. A one-percentage point decrease in interest rates would have affected interest expense on the debt by $4.3 million on an annualized basis.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Management has designed our disclosure controls and procedures to provide reasonable assurance of achieving the desired control objectives.
35

Table of Contents
As required by Exchange Act Rule 13a-15(b), we have carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2016. Based upon this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2016 to provide such reasonable assurance.
As previously disclosed, the Company is in the process of a multi-year implementation of a global enterprise resource planning system. In addition, in response to business integration activities, the Company has and will continue to further align and streamline the design and operation of the financial control environment to be responsive to the changing business model.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
Various lawsuits, claims and proceedings are pending or have been settled by us; the most significant of which are described below.
The Company is subject to various claims, lawsuits and proceedings in the ordinary course of the Company's business, including claims by current or former employees, distributors and competitors and with respect to its products and product liability claims, lawsuits and proceedings, some of which have been settled by the Company. In the opinion of management, such claims are either adequately covered by insurance or otherwise indemnified, or are not expected, individually or in the aggregate, to result in a material adverse effect on our financial condition. However, it is possible that the Company's results of operations, financial position and cash flows in a particular period could be materially affected by these contingencies.
TEI, acquired by Integra on July 17, 2015, manufactures a bovine-derived surgical mesh product for Boston Scientific Corporation ("BSC”) and has been named as a defendant in lawsuits under a broad range of products liability theories, many of which have not been served on TEI. Currently, there are approximately fifty active cases against TEI. Pursuant to an indemnification agreement with BSC (i) BSC is managing the litigation; (ii) TEI has in place a products liability insurance policy, of which it must exhaust $3.0 million before BSC’s indemnity begins to cover relevant claims (and of which only a small portion has been utilized to date and against which the insurer has reserved the entire $3.0 million). Because the thrust of products liability litigation focuses on synthetic surgical mesh products, counsel is filing motions to dismiss on behalf of TEI in many cases. In addition, Integra has certain protections in the merger agreements with TEI which would indemnify it for approximately $30.0 million for the first fifteen months after closing and between $20.0 and $30.0 million for the remainder of the three-year period after closing for losses relating to a variety of matters, including half of certain products liability claims (including those related to the product it manufactures for BSC) not covered by insurance.
The Company accrues for loss contingencies when it is deemed probable that a loss has been incurred and that loss is estimable. The amounts accrued are based on the full amount of the estimated loss before considering insurance proceeds, and do not include an estimate for legal fees expected to be incurred in connection with the loss contingency. The Company consistently accrues legal fees expected to be incurred in connection with loss contingencies as those fees are incurred by outside counsel as a period cost.
ITEM 1A. RISK FACTORS
The Risk Factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 have not materially changed.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
On October 28, 2014, our Board of Directors terminated the previous share repurchase plan dated October 2012, and authorized a new repurchase of up to $75.0 million of outstanding common stock through December 2016. Shares may be repurchased either in the open market or in privately negotiated transactions.
There were no repurchases of our common stock during the three months ended June 30, 2016 under this program.
ITEM 4. MINE SAFETY DISCLOSURES
