NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
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, 2015 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, 2014 included in the Company’s Annual Report on Form 10-K. The December 31, 2014 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, 2015 are not necessarily indicative of the results to be expected for the entire year.
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 pension assets and liabilities, 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.
Certain amounts from the prior year’s financial statements have been reclassified in order to conform to the current year’s presentation.
Recently Issued Accounting Standards
In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The amendments are effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2014 (early adoption is permitted only for disposals that have not been previously reported). The new guidance is effective for Integra prospectively for all disposals (or classifications as held for sale) of components of an entity that occur after January 1, 2015 and will be in effect for the spin-off of the spine business in the Company's third quarter 2015 results.
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. In July 2015, the FASB deferred for one year the effective date of the new revenue standard, but early adoption will be permitted. The new standard will be effective for the Company on January 1, 2018. 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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
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. 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 reporting periods beginning after December 15, 2015, including interim periods within that reporting period, and 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 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 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 will become effective for all annual periods and interim reporting periods beginning after December 15, 2015. The implementation of the amended guidance is not expected to have a material impact on the consolidated results of operations and will result in a reclassification of the debt issuance costs from other long-term assets to long-term debt when adopted.
There are no other recently issued accounting pronouncements that are expected to have a material effect on the financial position, results of operations or cash flows.
2. BUSINESS ACQUISITIONS
Metasurg
On December 5, 2014, the Company acquired certain assets of Koby Ventures II, L.P. dba Metasurg ("Metasurg") for an aggregate purchase price of $27.6 million (including working capital and purchase price adjustments of $0.4 million). The purchase price consists of an initial cash payment to Metasurg of $26.5 million, a separate purchase price adjustment cash payment of $0.4 million, and contingent consideration with an acquisition date fair value of $0.7 million. The potential maximum undiscounted contingent consideration of $38.5 million is based on reaching certain sales levels for acquired products from April 1, 2015 through June 30, 2016. The fair value of this liability is based on future sales projections of the Metasurg product under various potential scenarios and weighting the probability of these outcomes for the twelve-month period ended December 31, 2015. At the date of the acquisition, the cash flow projection was discounted using an internal rate of return of 19.9%. These fair value measurements were based on significant inputs not observed in the market and thus represented a Level 3 measurement.
Metasurg develops intuitive implant systems for the foot and ankle market and sells almost entirely in the U.S. market. The acquired foot and ankle products will enhance the Company's lower extremities market position.
The Company recorded revenue for Metasurg of approximately $1.7 million and $3.3 million in the condensed consolidated statements of operations for the three- and six-month period ended June 30, 2015. The net income or loss attributable to this acquisition cannot be identified on a stand-alone basis because it has been fully integrated into the Company's operations.
The Company adjusted the preliminary purchase price allocation during the quarter ended June 30, 2015 to reflect the $0.4 million working capital and purchase price adjustment. The following summarizes the preliminary allocation of the purchase price as of June 30, 2015 based on the fair value of the assets acquired and liabilities assumed:

MicroFrance
On October 27, 2014, the Company acquired all outstanding shares of Medtronic Xomed Instrumentation, SAS ("MicroFrance") from Medtronic, Inc. ("Medtronic") as well as certain assets of Medtronic for $60.1 million in cash (including working capital and purchase price adjustments of $1.5 million, of which $0.8 million was recorded against goodwill). MicroFrance specializes in manual ear, nose, and throat ("ENT") surgical instruments and designs, manufactures, and sells reusable handheld instruments to ENT and laparoscopy surgical specialists around the world. The acquired ENT instruments fill a portfolio gap for the Company with clear growth opportunities through market adjacencies and provides for increased scale and reach in the international market.
The Company recorded revenue for MicroFrance of approximately $6.3 million and $12.1 million in the condensed consolidated statements of operations for the three- and six-month period ended June 30, 2015. The net income or loss attributable to this acquisition cannot be identified on a stand-alone basis because it has been fully integrated into the Company's operations.
The Company adjusted the preliminary purchase price allocation during the quarter ended March 31, 2015 to reflect the $1.5 million working capital and purchase price adjustments. The following summarizes the final allocation of the purchase price as of June 30, 2015 based on the fair value of the assets acquired and liabilities assumed:

Accounts payable and other liabilities | 5,910 |  |
Net assets acquired | $ | 60,067 |  |

Confluent Surgical, Inc.
On January 15, 2014, the Company acquired all outstanding shares of Confluent Surgical, Inc., ("Confluent Surgical") - including its surgical sealant and adhesion barrier product lines - from Covidien Group S.a.r.l, ("Covidien") for an aggregate purchase price of $255.9 million. The purchase price consists of an initial cash payment to Covidien of $231.0 million upon the closing of the transaction, a separate prepayment of $4.0 million made under a transitional supply agreement with an affiliate of Covidien, and contingent consideration with an acquisition date fair value of $20.9 million. The potential maximum undiscounted contingent consideration of $30.0 million consists of $25.0 million upon obtaining certain U.S. governmental approvals and $5.0 million upon obtaining certain European governmental approvals, both related to the completion of the transition of the Confluent Surgical business to the Company.

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
The transitional supply agreement secures the supply of the acquired products from an affiliate of Covidien until the earlier of (i) the time that the transition of the Confluent Surgical business as discussed above is complete, or (ii) the fifth anniversary of the effective date of the agreement (the agreement also contains an option to extend for another two years by providing written notice at least 180 days prior to the end of the initial five-year period). This agreement contains financial incentives to the affiliate of Covidien for the timely supply of products each fiscal quarter through the third anniversary of the agreement. The prices paid under the supply agreement are essentially flat through the third anniversary of the agreement, and then increase significantly each of the following three years. The Company also entered into a transition services agreement with an affiliate of Covidien at the closing for services such as customer service, accounting and information technology management, clinical and regulatory affairs, manufacturing transition services, and other functions.
This acquisition complements the Company's global neurosurgery growth strategy aimed at providing a broader set of solutions for surgical procedures in the head.
The Company recorded revenue for Confluent Surgical of approximately $18.9 million and $36.6 million in the condensed consolidated statements of operations for the three- and six-month periods ended June 30, 2015 and $14.1 million and $32.4 million for the three- and six-month periods ended June 30, 2014. The net income or loss attributable to this acquisition cannot be identified on a stand-alone basis because it has been fully integrated into the Company's operations.
The Company adjusted the preliminary purchase price allocation during the quarter ended June 30, 2014 to reduce deferred tax liabilities by $12.4 million. This adjustment offset goodwill and was the result of the Company analyzing and revising its tax positions in certain jurisdictions. The following summarizes the final allocation of the purchase price as of June 30, 2015 based on the fair value of the assets acquired and liabilities assumed:

| Final Purchase Price Allocation |
| (Dollars in thousands) |
Inventory deposit | $ | 4,000 |  |
Fixed assets | 438 |  |
Intangible assets: |  |  | Wtd. Avg. Life
Technology product rights | 239,800 |  | 3 - 20 Years
Other | 400 |  | Less than 1 year
Deferred tax assets - long term | 12 |  |
Goodwill | 105,331 |  |
Total assets acquired | 349,981 |  |
Contingent supply liability | 5,891 |  |
Other | 731 |  |
Deferred tax liabilities - long term | 87,464 |  |
Net assets acquired | $ | 255,895 |  |

Subsequent to the acquisition date, a regulatory event occurred that resulted in the full-impairment of one of the acquired technology product rights of $0.6 million. This event was not known, or knowable, at the time of the acquisition and therefore the impairment has been included in the Company's cost of sales.
The Company accounted for the contingent supply liability by recording its fair value as a liability on the date of the acquisition based on a discounted cash-flow model. This contingent supply liability relates to contractual quarterly incentive payments that will be made to an affiliate of Covidien if certain supply minimums under the transitional supply agreement are met.
The Company accounted for the contingent consideration by recording its fair value as a liability on the date of the acquisition. The contingent consideration relates to the Company's obtaining certain U.S. and European regulatory approvals. At the date of the acquisition, both of these milestones were valued using a discount rate of 2.2%, which is equivalent to the cost of debt for the estimated time horizon, and an overall probability of occurring of 95%. Accordingly, on January 15, 2014 the Company recorded a $20.9 million liability representing the initial fair value estimate of the probability weighted contingent consideration that management believes will be paid between early 2017 and late 2018. Depending on the expected timing of the estimated payments, the acquisition date fair value of the probability adjusted payments could have been $0.3 million higher or $0.4 million lower. These fair value measurements were based on significant inputs not observed in the market and thus represented a Level 3 measurement. The contingent consideration is re-measured to fair value at each reporting date until the contingency is resolved, and those changes in fair value are recognized in earnings.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
The goodwill recorded in connection with these acquisitions is based on (i) expected cost savings, operating synergies and other benefits expected to result from the combined operations, (ii) the value of the going-concern element of the existing businesses (that is, the higher rate of return on the assembled net assets versus if the Company had acquired all of the net assets separately), and (iii) intangible assets that do not qualify for separate recognition such as an assembled workforce. The acquisitions generated a combination of deductible and non-deductible goodwill.
Contingent consideration
The Company increased the fair value of contingent consideration during the six-month period ended June 30, 2015 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, 2015 | $ | 22,008 |  |
Loss from increase in fair value of contingent consideration liabilities | 239 |  | Selling, general and administrative
Fair value at June 30, 2015 | $ | 22,247 |  |

The entire contingent consideration balance was included in Other liabilities at June 30, 2015 and December 31, 2014.
Pro Forma Results
The following unaudited pro forma financial information summarizes the results of operations for the three and six months ended June 30, 2014 as if the acquisitions completed by the Company during 2014 had been completed as of January 1, 2013. The pro forma results are based upon certain assumptions and estimates, and they give effect to actual operating results prior to the acquisition and adjustments to reflect (i) the change in interest expense, depreciation expense, and intangible asset amortization, (ii) certain external expenses related to the acquisition as if they were incurred on January 1, 2013 that will not be recurring in the post-acquisition periods, and (iii) income taxes on the aforementioned adjustments at the Company’s statutory rate. No effect has been given to other cost reductions or operating synergies. As a result, these pro forma results do not necessarily represent results that would have occurred if the acquisition had taken place on the basis assumed above, nor are they indicative of the results of future combined operations.

4. GOODWILL AND OTHER INTANGIBLE ASSETS
In the first quarter of 2015 the Company revised its reportable segments in connection with the realignment of its portfolio. Specifically, the Company integrated the five existing business divisions into three global divisions, no longer focusing on international as a separate reportable segment but managing each business globally. The change in reportable segments resulted in the Company's requirement to reallocate existing goodwill to the new reportable segments based on the relative-fair-value of
10

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
the Company's four underlying reporting units. With the reportable segments now being managed at a global level, goodwill previously assigned to the EMEA, LAPAC, and Private Label reporting units was reallocated to the new global reporting units. The Company estimated the fair value of the reporting units using a discounted cash flow model, which incorporates significant estimates and assumptions made by management which, by their nature, are characterized by uncertainty. Inputs used to fair value the Company's reporting units are considered inputs of the fair value hierarchy. For Level 3 measurements, significant increases or decreases in long-term growth rates or discount rates in isolation or in combination could result in a significantly lower or higher fair value measurement. The key assumptions impacting the valuation included the following:

• | The reporting unit's financial projections, which are based on management's assessment of regional and macroeconomic variables, industry trends and market opportunities, and the Company's strategic objectives and future growth plans.

• | The projected terminal value for the reporting unit, which represents the present value of projected cash flows beyond the last period in the discounted cash flow analysis. The terminal value reflects the Company's assumptions related to long-term growth rates and profitability, which are based on several factors, including local and macroeconomic variables, market opportunities, and future growth plans.

• | The discount rate used to measure the present value of the projected future cash flows is set using a weighted-average cost of capital method that considers market and industry data as well as the Company's specific risk factors that are likely to be considered by a market participant. The weighted-average cost of capital is the Company's estimate of the overall after-tax rate of return required by equity and debt holders of a business enterprise.

Based on the Company's fair value calculations, with the exception of the Spine reporting unit, given the excess of the Specialty Surgical Solutions Instruments, Specialty Surgical Solutions Neurosurgery, and Orthopedics and Tissue Technologies estimated fair value over their carrying value after the reallocation of goodwill, management concluded that any future goodwill impairment is not likely. The Company's allocation of goodwill to the Spine reporting unit has been impaired during the first quarter of 2015 as a result of the carrying value of its goodwill exceeding the implied fair value. Refer to Note 12 - Segment and Geographic Information for more information on the change in reportable segments.

During the six months ended June 30, 2014, the Company recorded an impairment charge of $0.6 million in cost of goods sold related to technology assets acquired from Confluent Surgical that will no longer be sold resulting from a regulatory event that occurred after the acquisition date.
Based on quarter-end exchange rates, annual amortization expense (including amounts reported in cost of product revenues, but excluding any possible future amortization associated with acquired in-process research and development) is expected to approximate $31.9 million in 2015, $29.7 million in 2016, $27.6 million in 2017, $27.3 million in 2018 and $26.5 million in 2019. Identifiable intangible assets are initially recorded at fair market value at the time of acquisition using an income or cost approach.
5. DEBT
Amended and Restated Senior Credit Agreement
On December 19, 2014, the Company entered into an amendment to the amended and restated credit agreement (the "Senior Credit Facility") which modified covenants to permit the distribution and/or dividend by the Company of its spine business to the Company's public stockholders. The intent of the amendment was to permit the Company to consummate the spine business spin-off transaction.
On July 2, 2014, the Company entered into the Senior Credit Facility with 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, Credit Agricole-Corporate and Investment Bank and TD Bank, N.A., as Co-Documentation Agents. The Company's Senior Credit Facility was originally amended and restated on August 10, 2010, and that agreement was then amended on June 8, 2011, May 11, 2012, and June 21, 2013, as previously disclosed.
The 2014 amended and restated Senior Credit Facility created an aggregate principal amount of up to $900.0 million available to the Company through the following facilities:

i. | a $750.0 million revolving credit facility (increased from $600.0 million), 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 $150.0 million term loan facility.

The Senior Credit Facility allows the Company to further increase the size of either the revolving credit facility or the term loan facility, or a combination thereof, by an aggregate of $200.0 million with additional commitments. 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.
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%, or

12

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

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, 2015 the Company was in compliance with all such covenants. In connection with the modification of the 2014 amendment and restatement of the Senior Credit Facility, the Company capitalized $3.2 million of incremental financing costs, and expensed $0.3 million of previously capitalized financing costs.
On July 2, 2014, the Company borrowed $422.0 million under the Senior Credit Facility consisting of a $150.0 million term loan and $272.0 million under its revolving credit facility. The Company used the funds to repay the balance of its previous Senior Credit Facility. The outstanding borrowings have one, two, three, six months, or, if available, twelve months interest periods.
At June 30, 2015 and December 31, 2014, there was $286.9 million and $266.9 million outstanding under the revolving credit component of the Senior Credit Facility at a weighted average interest rate of 2.0% and 1.7%, respectively. At June 30, 2015, there was approximately $463.1 million available for borrowing under the Senior Credit Facility. 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.
At June 30, 2015 there was $150.0 million outstanding under the term loan component of the Senior Credit Facility at a weighted average interest rate of 1.8%. Contractual repayments of the term loan do not begin until September 30, 2015 and are due as follows:

Year Ended December 31, |  | Principal Repayment
|  | (In thousands)
2015 |  | $ | 3,750 |
2016 |  | 9,375 |
2017 |  | 13,125 |
2018 |  | 15,000 |
2019 |  | 108,750 |
|  | $ | 150,000 |

The fair value of outstanding borrowings of the Senior Credit Facility's revolving credit facility and term loan components at June 30, 2015 was approximately $269.1 million and $143.0 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.
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%.
At June 30, 2015, the carrying amount of the liability component was $217.3 million, the remaining unamortized discount was $12.7 million, and the principal amount outstanding was $230.0 million. The fair value of the 2016 Notes at June 30, 2015 was approximately $285.8 million. At December 31, 2014, the carrying amount of the liability component was $213.1 million, the remaining unamortized discount was $16.9 million and the principal amount outstanding was $230.0 million. The fair value of
13

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
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.
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 17.4092 shares per $1,000 principal amount of 2016 Notes (which represents an initial conversion price of approximately $57.44 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. 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, 2,903 note holders provided notice to convert. The Company has classified the cash settlement of the conversion into short-term as of June 30, 2015. The remainder of the debt has continued to be classified as long-term as the conversion window has closed.
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 $57.44 per share, subject to customary anti-dilution adjustments. The initial strike price of the warrant transaction is approximately $70.05 per share, subject to customary anti-dilution adjustments. Refer to Note 14 - Subsequent Events for more information on the change in the conversion price as a result of the SeaSpine Separation.

6. DERIVATIVE INSTRUMENTS
Interest Rate Hedging
The Company’s interest rate risk relates to U.S. dollar denominated variable LIBOR interest rate borrowings. The Company uses an interest rate swap derivative instrument entered into on August 10, 2010 with an effective date of December 31, 2010 to manage its earnings and cash flow exposure to changes in interest rates by converting a portion of its floating-rate debt into fixed-rate debt beginning on December 31, 2010. This interest rate swap expires on August 10, 2015.
The Company designates this derivative instrument as a cash flow hedge. The Company records 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 affects earnings, at which point the effective portion of any gain or loss will be 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.
The Company expects that approximately $0.2 million of pre-tax losses recorded as net in AOCI related to the interest rate hedge could be reclassified to earnings prior to the date of expiration.
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
14

INTEGRA LIFESCIENCES HOLDINGS CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
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.
There were no contracts outstanding as of June 30, 2015.
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.
The following table summarizes the fair value and presentation for derivatives designated as hedging instruments in the condensed consolidated balance sheets as of June 30, 2015 and December 31, 2014:

|  | Fair Value as of
Location on Balance Sheet (1): |  | June 30, 2015 |  | December 31, 2014

(1) | The Company classifies derivative assets and liabilities as current based on the cash flows expected to be incurred within the following 12 months.

(2) | At June 30, 2015 and December 31, 2014, the notional amount related to the Company’s sole interest rate swap was $90.0 million and $97.5 million, respectively. In the next twelve months, the Company expects to reduce the notional amount by the entire $90.0 million.

The Company recognized no gains or losses resulting from ineffectiveness of cash flow hedges during the six months ended June 30, 2015 and 2014.
7. STOCK-BASED COMPENSATION
As of June 30, 2015, 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.
Stock Options
As of June 30, 2015, there were approximately $2.4 million of total unrecognized compensation costs related to unvested stock options. These costs are expected to be recognized over a weighted-average period of approximately two years. There were 77,347 stock options granted during the six months ended June 30, 2015.

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, 2015, there were approximately $18.4 million of total unrecognized compensation costs related to these unvested awards. The Company expects to recognize these costs over a weighted-average period of approximately two years. The Company granted 146,300 restricted stock awards/stock units and 64,930 performance shares during the six months ended June 30, 2015.
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.
8. TREASURY STOCK
On October 28, 2014, the Board of Directors terminated the October 2012 authorization and authorized up to $75.0 million of its outstanding common stock through December 2016. The Company has not repurchased any of its outstanding shares of common stock during the six-month periods ended June 30, 2015 and 2014. As of June 30, 2015, there remained $75.0 million available for repurchases under this authorization.
9. 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,
| 2015 |  | 2014 |  | 2015 |  | 2014
Reported tax rate | 34.0 | % |  | 32.9 | % |  | 33.7 | % |  | 37.0 | %

The Company’s effective income tax rates for the three months ended June 30, 2015 and 2014 were 34.0% and 32.9%, respectively. The primary drivers of the higher tax rate for the three months ended June 30, 2015 were a tax expense of $0.4 million for nondeductible costs relating to the spine spin-off transaction and a tax expense of $0.4 million relating to foreign tax returns filed during the quarter.
The Company's effective income tax rates for the six months ended June 30, 2015 and 2014 were 33.7% and 37.0%, respectively. The primary drivers of the overall tax rate for the six months ended June 30, 2014 were a tax expense of $1.1 million relating to foreign and state income tax audit settlements and a tax expense of $0.3 million relating to a change in state filing positions.
The Company expects its effective income tax rate for the full year to be approximately 32%, resulting largely from nondeductible spine spin-off costs and audit settlements offset by the release of uncertain tax positions, as well as 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.

Weighted average common shares for diluted earnings per share | 33,939 |  |  | 32,804 |  |  | 33,644 |  |  | 32,796 |
Diluted net income per common share | $ | 0.15 |  |  | $ | 0.15 |  |  | $ | 0.40 |  |  | $ | 0.21 |

At June 30, 2015 and 2014, the Company had 1.1 million and 1.4 million of outstanding stock options, respectively. The Company also has warrants outstanding relating to its 2016 Notes at June 30, 2015 and 2014 and the Company's 2016 Notes are convertible to common shares in certain circumstances (see Note 5). Stock options, restricted stock, warrants and the excess conversion value of the 2016 Notes are included in the diluted earnings per share calculation using the treasury stock method, unless the effect of including such items would be anti-dilutive.
For the three months ended June 30, 2015 and 2014, 0.1 million and 0.2 million, respectively, of anti-dilutive stock options were excluded from the diluted earnings per share calculation. For the six months ended June 30, 2015 and 2014, a minimal amount and 0.2 million, respectively, of anti-dilutive stock options were excluded from the diluted earnings per share calculation. The effect of outstanding warrants were anti-dilutive because the strike price of the warrants exceeded the Company’s average stock price for the periods presented.
For the three and six months ended June 30, 2015, the potential excess conversion value on the 2016 Notes was included in the Company's dilutive share calculation because the average stock price for the three and six months ended June 30, 2015 exceeded the conversion price. The potential excess conversion value of the 2016 Notes were anti-dilutive because the conversion price exceeded the Company's stock price for the three and six months ended June 30, 2014; therefore, these amounts have been excluded from the diluted earnings per share calculation.

12. SEGMENT AND GEOGRAPHIC INFORMATION
Starting in the first quarter of 2015, because of changes in how the Company internally manages and reports the results of its businesses to its chief operating decision maker, the Company is disclosing three global reportable segments. The three global reportable segments and their activities are described below, as follows:

• | The Specialty Surgical Solutions segment includes (i) the Neurosurgery business which sells a full line of products specifically for neurosurgery and critical care such as tissue ablation equipment, dural repair products, cerebral spinal fluid management devices, intracranial monitoring equipment, and cranial stabilization equipment and (ii) the Instruments business which sells more than 60,000 instrument patterns and surgical and lighting products to hospitals, surgery centers, and dental, podiatry, and veterinary offices.

• | The Orthopedics and Tissue Technologies segment includes such offerings as skin and wound repair, bone and joint fixation, implants in the upper and lower extremities, bone grafts and nerve and tendon repair.

• | The Spine segment focuses on spinal fusion, spinal implants, and deformity correction, together with bone graft substitutes and other related medical devices that are used to enhance the repair and regeneration of bone in various types of orthopedic surgical procedures. Subsequent to June 30, 2015, this operating segment was eliminated due to the spin-off of the SeaSpine business. Refer to Note 14 - Subsequent Events for additional information.

The most notable change from the Company's financial statements for the year ended December 31, 2014 included in the Annual Report on Form 10-K is the integration of the former International reportable segment into the segments noted above as well as the Private Label segment into Orthopedics and Tissue Technologies and Spine.
The Corporate and other category includes (i) various legal, finance, information systems, executive, and human resource functions, (ii) brand management, and (iii) share-based compensation costs. Prior to the realignment, costs related to procurement, manufacturing operations and logistics for the Company's entire organization were not allocated to operating segments. In connection with the realignment, a portion of these costs have now been incorporated into the disclosed operating segments.
The operating results of the various reportable segments as presented are not comparable to one another because (i) certain operating segments are more dependent than others on corporate functions for unallocated general and administrative and/or operational manufacturing functions, and (ii) the Company does not allocate certain manufacturing costs and general and administrative costs to the operating segment results. Net sales and profit by reportable segment for the three and six months ended June 30, 2015 and 2014 are as follows:

13. 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.
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.

14. SUBSEQUENT EVENTS
SeaSpine Separation
On November 1, 2014, the Company announced plans to spin-off the spine business into a stand-alone public company ("SeaSpine"). On July 1, 2015, the Company completed the distribution of 100% of the outstanding common shares of SeaSpine to Integra 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. The historical results of operations and the financial position of SeaSpine are included in the consolidated financial statements of Integra and will be reported as discontinued operations beginning in the third quarter of 2015.
As a result of the spin-off and pursuant to the indenture for the Company's 2016 Notes, the conversion price and rate is required to be adjusted. The conversion price on the 2016 Notes has been adjusted to $52.83 per share and the new conversion rate is 18.9287 shares per $1,000 principal amount of 2016 Notes. Similarly, the strike price of the call transaction has been adjusted to $52.83 per share and the warrant transaction has been adjusted to $64.43 per share.
Acquisition of TEI Biosciences, Inc. and TEI Medical, Inc.
On July 17, 2015, the Company completed the execution of the two merger agreements (collectively, the "Agreements") under which the Company acquired TEI Biosciences, Inc., a Delaware corporation ("TEI Bio"), and TEI Medical Inc., a Delaware corporation ("TEI Med", collectively "TEI").
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 is a spin-off of TEI Bio and holds a license to TEI Bio’s regenerative technology in the fields of wound healing and orthopedics.
Under the terms of the Agreements, the Company paid $312.0 million ($211.0 million for TEI Bio and $101.0 million for TEI Med) subject in each case to purchase price adjustments for certain working capital changes. In July 2015, the Company drew $310.0 million on its Revolving Credit Facility to facilitate this transaction. The Company has not yet performed the purchase price allocation and will do so in the third quarter of 2015.
TEI manufactures a bovine-derived surgical mesh product for Boston Scientific Corporation ("BSC”) and has been named as a defendant in several hundred lawsuits under a broad range of products liability theories, many of which have not been served on TEI. Currently, there are approximately forty-five 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.
ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL
Integra is a world leader in medical technology focused on limiting uncertainty for surgeons so that they can concentrate on providing the best patient care. Integra offers innovative solutions in orthopedic extremity surgery, neurosurgery, spine surgery, and reconstructive and general surgery.
In the first quarter of 2015, we changed how we manage the business. As a result, we report our financial results under three global reportable segments - Specialty Surgical Solutions, Orthopedics and Tissue Technologies, and Spine. Refer to Note 12 - Segment and Geographic Information for more information.
Our Specialty Surgical Solutions segment includes, among other things, dural grafts and dural sealants which are indicated for the repair of the dura mater, ultrasonic surgery systems for tissue ablation, monitoring systems for neuro critical care, cranial stabilization and retraction systems, and a wide range of specialty and general surgical and dental instruments and surgical lighting for sale to hospitals, outpatient surgery centers, and physician, veterinarian and dental practices. Our Orthopedics and Tissue Technologies segment includes specialty metal implants for surgery of the upper and lower extremities, dermal regeneration products and tissue-engineered wound dressings and nerve and tendon repair products. Our Spine segment focuses on orthobiologics and spinal fusion hardware solutions used to meet the varying combinations of products that neurosurgeons and orthopedic spine surgeons need to perform fusion procedures in the lumbar, thoracic and cervical spine.
We manufacture many of our products in plants located in the United States, Puerto Rico, France, Germany, Ireland, and Mexico. We also source most of our handheld surgical instruments and specialty metal and pyrocarbon implants through specialized third-party vendors.
Our products in each reportable segment are sold through a combination of a direct sales organization and distributors.
We also market certain products through strategic partners in the United States.
We aspire to be 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 worldwide and by becoming a top player in all markets in which we compete.
Our strategy is built around three pillars - optimize, execute and accelerate growth. These three pillars support our strategic initiatives to optimize our infrastructure, to deliver on our commitments through improved planning and communication, and to grow by introducing new products to the market through internal development, expanding geographically, and strategic acquisitions.
Acquisitions
TEI Biosciences, Inc. and TEI Medical, Inc.
Subsequent to June 30, 2015, on July 17, 2015, the Company completed the execution of the two merger agreements (collectively, the "Agreements") under which the Company acquired TEI Biosciences, Inc., a Delaware corporation ("TEI Bio"), and TEI Medical Inc., a Delaware corporation ("TEI Med").
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 is a spin-off of TEI Bio and holds a license to TEI Bio’s regenerative technology in the fields of wound healing and orthopedics.
Under the terms of the Agreements, we paid $312.0 million ($211.0 million for TEI Bio and $101.0 million for TEI Med) subject in each case to purchase price adjustments for certain working capital changes.
Metasurg
In December 2014, we acquired certain assets of Koby Ventures II, L.P. dba Metasurg ("Metasurg") for an aggregate purchase price of $27.6 million. The purchase price consists of an initial cash payment to Metasurg of $26.5 million, a separate purchase price adjustment cash payment of $0.4 million, and contingent consideration with an acquisition date fair value of $0.7 million. The potential maximum undiscounted contingent consideration of $38.5 million is based on reaching certain sales levels for acquired products from April 1, 2015 through June 30, 2016. Metasurg develops intuitive implant systems for the foot and ankle market and sells almost entirely in the U.S. market.
MicroFrance
In October 2014, we acquired all outstanding shares of Medtronic Xomed Instrumentation, SAS ("MicroFrance") from Medtronic, Inc. ("Medtronic") as well as certain assets of Medtronic for $60.1 million in cash (including working capital and purchase price adjustments of $1.5 million, of which $0.8 million was recorded against goodwill). MicroFrance specializes in manual ear, nose, and throat ("ENT") surgical instruments and designs, manufactures, and sells reusable handheld instruments to ENT and laparoscopy surgical specialists around the world.

Confluent Surgical, Inc.
In January 2014, we acquired all outstanding shares of Confluent Surgical, Inc., ("Confluent Surgical") - including its surgical sealant and adhesion barrier product lines - from Covidien Group S.a.r.l, ("Covidien") for an aggregate purchase price of $255.9 million. The purchase price consists of an initial cash payment to Covidien of $231.0 million upon the closing of the transaction, a separate prepayment of $4.0 million made under a transitional supply agreement with an affiliate of Covidien, and contingent consideration with an acquisition date fair value of $20.9 million. The potential maximum undiscounted contingent consideration of $30.0 million consists of $25.0 million upon obtaining certain U.S. governmental approvals and $5.0 million upon obtaining certain European governmental approvals, both related to the completion of the transition of the Confluent Surgical business to us. Confluent Surgical is a developer and supplier of polymer-based biosurgery technology used in surgical sealants and anti-adhesion products.
The transitional supply agreement secures the supply of the acquired products from an affiliate of Covidien until the earlier of (i) the time that the transition of the Confluent Surgical business as discussed above is complete, or (ii) the fifth anniversary of the effective date of the agreement (the agreement also contains an option to extend for another two years by providing written notice at least 180 days prior to the end of the initial five-year period). This agreement contains financial incentives to the affiliate of Covidien for the timely supply of products each fiscal quarter through the third anniversary of the agreement. The prices paid under the supply agreement are essentially flat through the third anniversary of the agreement, and then increase significantly each of the following three years. We also entered into a transition services agreement with an affiliate of Covidien at the closing for services such as customer service, accounting and information technology management, clinical and regulatory affairs, manufacturing transition services, and other functions.
This acquisition complements our global neurosurgery growth strategy aimed at providing a broader set of solutions for surgical procedures in the head.
Diabetic Foot Ulcer Clinical Trial
During July 2014, we completed our multicenter 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 Supplement application that we filed with the FDA, which we announced in February 2015. In addition, the results from our Integra DFU clinical trial have been accepted by an important peer-reviewed wound journal. An FDA approval, along with published data, will form the key to securing reimbursement. Assuming FDA approval and timely publication of the peer-reviewed journal article, the Company anticipates commercializing the resulting DFU product in the middle of 2016.
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 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 pre-separation expenses of approximately $9.9 million and $14.8 million in the three and six months ended June 30, 2015, respectively. Pre-separation costs included all incremental expenses incurred by Integra in order to effect the separation until the distribution date, July 1, 2015. They also included the cost of all new employees recruited to operate the two separate companies. We also expect to incur, upon separation, transaction expenses, which, among other things, relate to advisory fees as well as tax costs related to the distribution. Total post-separation costs are expected to be approximately $5.2 million which includes a non-cash stock compensation charge. The historical results of operations and the financial position of SeaSpine are included in the consolidated financial statements of Integra and will be reported as discontinued operations beginning in the third quarter of 2015.
Realignment of the Integra Portfolio and Change in Reportable Segments
In the first quarter of 2015, the Company's management began reporting business performance and making decisions primarily on a global basis, including the results of its former International reportable segment in each of its respective three division global structure. Following the above announced separation of the Spine business, we will have the two remaining global segments. Accordingly, to align with the way the business is currently managed, the Company’s reportable operating segments now consist of Specialty Surgical Solutions, Orthopedics and Tissue Technologies, and Spine. International is no longer reported as a separate reportable operating segment. Specialty Surgical Solutions includes the i) Neurosurgery business, the ii) Instruments business and iii) their respective international components, Orthopedics and Tissue Technologies includes the former U.S. Extremities business and its international components, and the Spine reportable segment includes the former U.S. Spine operating segment and its respective international components. Private Label has been incorporated in the reportable segments based on the nature of the product line. Further information regarding the Company’s operating segments may be found in Note 12 - Segment and Geographic Information.

RESULTS OF OPERATIONS
Executive Summary
Net income for the three months ended June 30, 2015, was $5.0 million, or $0.15 per diluted share as compared to $4.8 million or $0.15 per diluted share for the three months ended June 30, 2014.
Net income for the six months ended June 30, 2015 was $13.4 million or $0.40 per diluted share as compared to $7.0 million or $0.21 per diluted share for the six months ended June 30, 2014.
The increase in net income for the six months ended June 30, 2015 over the same period last year resulted primarily from the inclusion of the MicroFrance and Metasurg operations as well as strong growth in our dural repair and regenerative technology franchises.
Income before taxes includes the following special charges:

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. In 2010, we began investing significant resources in the global implementation of a single enterprise resource planning ("ERP") system. We began capitalizing certain costs for the project starting in 2011 and continued to do so during the first half of 2015. We placed the ERP in service across a number of U.S. sites in May of 2014, and at that time, we began depreciating the capitalized costs associated with that part of the implementation. We expect the additional capital and integration expenses associated with our ERP system to decrease as we continue to progress in our ERP implementation over the next several years.
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 assessing comparability of our operating performance from period to period, the business model objectives that management has established, and 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
The FDA inspected our Andover, UK facility (the "Andover Facility") in June 2012, which resulted in the issuance of FDA Form 483 Observations. We subsequently received a Warning Letter on November 1, 2012. On April 25, 2014, we received a letter from the FDA stating that while it accepted the Corrective Action Plan for the Andover Facility, the warning letter would not be closed out until the FDA conducted an inspection of the Andover facility and concluded that the violations stated in the FDA warning letter had been addressed. On December 31, 2014, we closed the Andover Facility and delisted it as an FDA registered facility. We notified the FDA regarding the closure of the Andover Facility, and most of the products were moved to our facility in Tullamore, Ireland (the "Tullamore Facility"). The FDA inspected the Tullamore Facility in March 2015 and no FDA Form 483 Observations were issued. One June 30, 2015, the FDA issued a letter to the Company informing us that we had addressed the violations in the FDA warning letter dated November 1, 2012 related to the Andover Facility and that such warning letter had been closed out effective June 30, 2015.
We have an outstanding FDA warning letter related to TEI Biosciences Inc., a recent acquisition by Integra on July 17, 2015. TEI Biosciences Inc. received a Warning Letter from the FDA dated May 29, 2015 for promoting the product SurgiMend for breast surgery applications that was not cleared in the 510(k) process and does not have a PMA Approval for the indication. The FDA requested that TEI Biosciences Inc. immediately cease all activities that resulted in misbranding or adulteration of the product in commercial distribution. The FDA also required TEI Biosciences Inc. to cease all violations regarding promotion of the product for an indication that it was not cleared or approved. TEI Biosciences Inc. responded with a corrective action plan to the FDA. 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.
The FDA inspected our Añasco, Puerto Rico facility in October and November 2012, and issued a warning letter for that facility on February 13, 2013. On November 26, 2013, the FDA completed its second inspection of the Añasco facility and issued a new Form 483 with six additional observations. On September 30, 2014, the FDA completed its third inspection of the Añasco facility, and concluded that the Company had addressed the issues raised in the Warning Letter and previous inspectional observations, and it issued no other inspectional observations. The Añasco warning letter was closed out effective January 14, 2015.
There were no remediation expenses incurred in the three-and six-months ended June 30, 2015 and an insignificant amount of expenses were incurred in the three-and six-months ended June 30, 2014.

Three Months Ended June 30, 2015 as Compared to Three Months Ended June 30, 2014
Revenues and Gross Margin
For the three months ended June 30, 2015 total revenues increased by $12.7 million to $244.1 million from $231.4 million for the same period in 2014.
Specialty Surgical Solutions revenues were $146.7 million, an increase of 7% from the prior-year period. The increase partially resulted from the impact of the MicroFrance product sales arising out of the acquisition, which added $6.3 million in the quarter. Global sales of our Dural repair products increased in line with the overall segment. 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, particularly in the U.S. These increased sales were partially offset by a decline in tissue ablation and neuro critical care.
Orthopedics and Tissue Technologies revenues were $63.8 million, an increase of 10% from the prior-year period. The increase partially resulted from the impact of the Metasurg product sales arising out of the acquisition, which added $1.7 million in the quarter. We continue to see strong demand in our regenerative technologies franchise as a result of both additional headcount in our sales force and new products, including the Integra Wound Matrix-Thin, Integra Reinforcement Matrix and Integra Wound Matrix-Meshed. Sales growth in our upper extremity franchise also benefited from increasing demand for new products in shoulder and wrist arthroplasty. These increased sales were partially offset by a decline in our lower extremities franchise.
Spine revenues were $33.5 million, a decrease of 7% from the prior-year period. The decrease was mostly driven by our spine hardware business, which continued to face pricing pressures, delays in product launches, and the slower than anticipated addition of new distributors. Our orthobiologics business was up slightly during the quarter.
Gross margin increased to $157.5 million for the three-month period ended June 30, 2015 from $144.4 million for the same period last year. Gross margin as a percentage of total revenue increased to 64.5% for the second quarter of 2015 from 62.4% 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, and improvements in the utilization of our manufacturing facilities.
We expect our consolidated gross margin percentage for the full year 2015 to be between 63.5% and 64.0%. We expect our gross margin will see increases from improved product mix offset by a negative top-line impact on revenues because of the stronger U.S. dollar and corresponding weaknesses in other currencies in which we transact business, particularly the euro, as well as additional costs related to the completion of our regenerative technology manufacturing facility capacity expansion.
Operating Expenses
The following is a summary of operating expenses as a percent of total revenues:

| Three Months Ended June 30,
| 2015 |  | 2014
Research and development | 5.7 | % |  | 5.9 | %
Selling, general and administrative | 51.9 | % |  | 49.8 | %
Intangible asset amortization | 1.3 | % |  | 1.3 | %
Total operating expenses | 58.9 | % |  | 57.0 | %

Total operating expenses, which consist of research and development expenses, selling, general and administrative expenses, and amortization expense, increased $11.6 million, or 9%, to $143.6 million in the three months ended June 30, 2015, compared to $132.0 million in the same period last year.
Research and development expenses in the second quarter of 2015 remained flat compared to the same period last year. We expect full-year 2015 spending on research and development to be approximately 5.5% of total revenues.
Selling, general and administrative expenses in the second quarter of 2015 increased by $11.3 million to $126.6 million compared to $115.3 million in the same period last year. Selling and marketing expenses increased by $3.1 million, primarily resulting from higher commissions and distributor fees related to the MicroFrance and Metasurg sales, increased headcount and overall sales increases in general. General and administrative costs increased $8.2 million as a result of incremental costs to support the spin-off of our Spine business as well as additional depreciation as we implemented our ERP in certain locations during May of 2014. These increases were partially offset by a decrease in integration costs related to the Covidien Surgical acquisition recorded in the

first quarter of 2014. We expect full year selling, general and administrative expenses to be approximately 46.5% of revenues, including costs related to the spin-off of our spine business.
Amortization expense as a percentage of revenues in the second quarter of 2015 remained flat compared to the same period last year.
Non-Operating Income and Expenses
The following is a summary of non-operating income and expenses:

| Three Months Ended June 30,

| (In thousands)
Interest income | $ | 8 |  |  | $ | 58 |
Interest expense | (5,471 | ) |  | (5,382 | )
Other (expense) income, net | (919 | ) |  | 118 |

Interest Income and Interest Expense
Interest expense in the three months ended June 30, 2015 increased by $0.1 million primarily because we increased borrowings on our Senior Credit facility compared to the prior year. Our reported interest expense for the three-month periods ended June 30, 2015 and 2014 includes non-cash interest related to the accounting for convertible securities of $1.9 million and $1.8 million, respectively.
Interest income was negligible for the three months ended June 30, 2015, and 2014.
Other Income
Other income for both the second quarter of 2015 and 2014 was primarily attributable to the foreign exchange impact on intercompany balances.
Income Taxes

| Three Months Ended June 30,
| 2015 |  | 2014
| (In thousands)
Income before income taxes | $ | 7,572 |  |  | $ | 7,186 |
Income tax expense | 2,574 |  |  | 2,361 |
Effective tax rate | 34.0 | % |  | 32.9 | %

The Company’s effective income tax rates for the three months ended June 30, 2015 and 2014 were 34.0% and 32.9%, respectively. The primary drivers of the higher tax rate for the three months ended June 30, 2015 were a tax expense of $0.4 million for nondeductible costs relating to the spine spin-off transaction and a $0.4 million relating to foreign tax returns filed during the quarter.
The Company expects its effective income tax rate for the full year to be approximately 32%, resulting largely from nondeductible spine spin-off costs and audit settlements offset by the release of uncertain tax positions, as well as the jurisdictional mix of pretax income in U.S.-based operations relative to foreign operations.
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 know 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, 2015 as Compared to Six Months Ended June 30, 2014
Revenues and Gross Margin
For the six months ended June 30, 2015, total revenues increased by $31.3 million to $477.7 million from $446.4 million during the prior-year period.
Specialty Surgical Solutions revenues were $286.8 million, an increase of 8% from the prior-year period. The increase partially resulted from the impact of the MicroFrance product sales arising out of the acquisition, which added $12.1 million for the six months ended June 30, 2015. 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. Neuro critical care increased slightly during the period. These increased sales were partially offset by a decline in tissue ablation.
Orthopedics and Tissue Technologies revenues were $125.2 million, an increase of 11% from the prior-year period. The increase partially resulted from the impact of the Metasurg product sales arising out of the acquisition, which added $3.3 million for the six months ended June 30, 2015. The increase was driven by strong demand in our regenerative technologies franchise as a result of both additional headcount in our sales force and new products, including the Integra Wound Matrix-Thin, Integra Reinforcement Matrix and Integra Wound Matrix-Meshed. Sales growth in our upper extremity franchise benefited from increasing demand for new products in shoulder and wrist arthroplasty. These increased sales were partially offset by a decline in lower extremities.
Spine revenues were $65.8 million, a decrease of 5% from the prior-year period. The decrease was mostly driven by our spine hardware business which continued to face pricing pressures, delays in product launches, and the slower than anticipated addition of new distributors. Our orthobiologics business increased slightly during the six month period.
Gross margin increased to $304.5 million for the six-month period ended June 30, 2015 from $277.1 million for the same period last year. Gross margin as a percentage of total revenue increased to 63.7% for the first-half of 2015 from 62.1% 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, and improvements in our utilization of manufacturing facilities.
Operating Expenses

Total operating expenses | 57.3 | % |  | 57.3 | %

Total operating expenses, which consist of research and development expenses, selling, general and administrative expenses, and amortization expense, increased $17.8 million, or 7.0%, to $273.7 million in the first six months of 2015, compared to $255.9 million in the same period last year.
Research and development expenses in the first six months of 2015 remained flat compared to the same period last year.
Selling, general and administrative expenses in the first six months of 2015 increased by $17.1 million to $240.7 million compared to $223.6 million in the same period last year. Selling and marketing expenses increased by $7.2 million primarily resulting from higher commissions and distributor fees related to the MicroFrance and Metasurg sales, increased headcount and overall sales increases in general. General and administrative costs increased $9.9 million primarily because of incremental costs to support the spin-off of our Spine business as well as additional depreciation as we put our ERP system in service in certain locations during May of 2014.
Amortization expense in the first six months of 2015 increased by $0.6 million to $6.6 million, compared to $6.0 million in the same period last year. Amortization expense in the first half of 2015 reflects the Spine goodwill impairment charge of $0.4 million.

The Company's effective income tax rates for the six months ended June 30, 2015 and 2014 were 33.7% and 37.0%, respectively. The primary drivers of the overall tax rate for the six months ended June 30, 2014 were a tax expense of $1.1 million relating to foreign and state income tax audit settlements and a tax expense of $0.3 million relating to a change in state filing positions.
The Company expects its effective income tax rate for the full year to be approximately 32%, resulting largely from nondeductible spine spin-off costs and audit settlements offset by the release of uncertain tax positions, as well as the jurisdictional mix of pretax income in U.S.-based operations relative to foreign operations.
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 the various taxing authorities. We consider these factors and others, including our history of generating taxable earnings, in assessing our ability to realize deferred tax assets on a quarterly basis.

Changes in foreign exchange rates decreased our sales by $12.5 million in the six- month period compared to the same period last year.
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.
LIQUIDITY AND CAPITAL RESOURCES
Cash and Marketable Securities
We had cash and cash equivalents totaling approximately $131.3 million and $72.0 million at June 30, 2015 and December 31, 2014, respectively, which are valued based on Level 1 measurements in the fair value hierarchy. At June 30, 2015, our non-U.S. subsidiaries held approximately $70.0 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.

Table of Contents
In 2015, we anticipate that our principal uses of cash will include between $40.0 million and $45.0 million on capital expenditures primarily for the completion of our regenerative technology manufacturing capacity expansion, support and maintenance in our existing plants, our enterprise resource planning system implementation, and additions to our instrument kits used in sales of orthopedic products. In addition, we provided $47.0 million of cash to the spine business in conjunction with the spin-off and we expect total costs to be approximately $20.0 million for professional fees and other expenses to separate the business and build the corporate infrastructure.
Cash Flows Provided by Operating Activities
We generated operating cash flows of $49.7 million and $27.6 million for the six months ended June 30, 2015 and 2014, respectively.
Operating cash flows for the six months ended June 30, 2015 benefited from an increase in net income of $6.4 million compared to the same period in 2014. Changes in working capital decreased cash flows for the six months ended June 30, 2015 by approximately $2.9 million. Among the changes in working capital, accounts receivable used $4.5 million of cash, inventory used $9.9 million of cash, prepaid expenses and other current assets used $7.3 million of cash, and accounts payable, accrued expenses and other current liabilities provided $19.6 million of cash.
Operating cash flow for the six months ended June 30, 2014 benefited from an increase in net income of $11.5 million compared to the same period in 2013. Changes in working capital decreased cash flows by approximately $15.1 million. Among the changes in working capital, accounts receivable provided $0.1 million of cash, inventory used $17.4 million of cash, prepaid expenses and other current assets used $2.8 million of cash, and accounts payable, accrued expenses and other current liabilities used $4.8 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 facility and $1.8 million related to a working capital adjustment from the MicroFrance acquisition. We also paid $22.0 million for capital expenditures, most of which was directed to the expansion of our regenerative medicine production capacity and global enterprise system implementation.
During the six months ended June 30, 2014, we paid $235.0 million for the acquisition of Confluent Surgical, and $20.7 million for capital expenditures, most of which was directed to the expansion of our regenerative medicine production capacity and global enterprise system implementation.
Cash Flows Provided by Financing Activities
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 from stock option exercises of $7.3 million and borrowed $35.0 million under our Senior Credit Facility to fund SeaSpine in conjunction with the spin-off.
Our principal sources of cash for financing activities in the six months ended June 30, 2014 were $235.0 million of borrowings under our senior credit facility to fund the Confluent Surgical acquisition and stock option exercises of $8.3 million.
Working Capital
At June 30, 2015 and December 31, 2014, working capital was $452.5 million and $403.3 million, respectively.
Amended and Restated Senior Credit Agreement, Convertible Debt and Related Hedging Activities
See Note 5 - 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.
The Company is currently in discussions with its lenders to increase the size of the term loan under the Senior Credit Facility by an aggregate principal amount of $200.0 million. The intended use of proceeds of the increase in the term loan is repayment of outstanding amounts under the revolving credit facility. It is possible that the amount of the increase will change, and there can be no assurance that the Company and the lenders will reach final agreement on any such increase.
Share Repurchase Plan
On October 28, 2014, our Board of Directors terminated the previous share repurchase plan dated October 23, 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. As of June 30, 2015, there remained $75.0 million available for repurchases under this authorization.

Table of Contents
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.
Contractual Obligations and Commitments
As of June 30, 2015, we were obligated to pay the following amounts under various agreements:

|  |  | Payments Due by Calendar Year

(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 5 - Debt of our condensed consolidated financial statements for additional information.
(2 | ) | The Company may borrow and make payments against the revolver 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 $22.2 million at June 30, 2015. 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 $1.2 million at June 30, 2015. 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, 2015 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 is 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, Swiss francs, British pounds, Canadian dollars, Australian dollars and Japanese yen. 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, 2015 would increase interest income by approximately $1.3 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 2 basis points. 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 by utilizing a forward-starting interest rate swap that began to offset a portion of our interest payments in the first quarter of 2011. This interest rate derivative
34

Table of Contents
instrument fixed the interest rate on a portion of our expected LIBOR-indexed floating-rate borrowings beginning on December 31, 2010. The interest rate swap had a notional amount of $90.0 million outstanding as of June 30, 2015. We recognized $0.4 million of additional interest expense related to this derivative during the three months ended June 30, 2015. The fair value of our interest rate derivative instrument was a net liability of $0.2 million at June 30, 2015.
Based on our outstanding borrowings at June 30, 2015, a one-percentage point change in interest rates would have affected interest expense on the unhedged portion of the debt by $3.5 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.
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, 2015. 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, 2015 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 (“ERP”) 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, 2015 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, a recent acquisition 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 several hundred lawsuits under a broad range of products liability theories, many of which have not been served on TEI. Currently, there are approximately forty-five 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, 2014 have not materially changed except as noted below.
We may not achieve some or all of the anticipated benefits of the separation of our Spine business.
On July 1, 2015, we completed the separation (the “Separation”) of our orthobiologics and spinal fusion hardware business, now known as SeaSpine Holdings Corporation (“SeaSpine”), from the Company. Even though the Separation has been completed, we may not realize any or all of the anticipated strategic, financial, operational, marketing or other benefits from the Separation, including our ability to benefit from the increased focus through our new two divisional structure or to achieve anticipated growth rates, margins and scale and to execute on our strategy generally. Following the Separation, we are a smaller, less diversified company. This narrower business focus may leave us more vulnerable to changing market conditions, which could materially and adversely affect our business, financial condition and results of operations. The diminished diversification of revenue, costs, and cash flows could also cause our results of operations, cash flows, working capital and financing requirements to be subject to increased volatility. In addition, we may be unable to achieve some or all of the strategic and financial benefits that we expected would result from the Separation, or such benefits may be delayed, which could materially and adversely affect our business, financial condition and results of operations. Further, there can be no assurance that the combined value of the common stock of the two publicly-traded companies will be equal to or greater than what the value of our common stock would have been had the Separation not occurred.
Following the Separation, SeaSpine will continue to be dependent on us for certain support services and we may have indemnification obligations to each other with respect to such arrangements.
We entered into various agreements with SeaSpine in connection with the Separation, including a transition services agreement, a separation and distribution agreement, a tax matters agreement, an employee matters agreement and several supply agreements. These agreements will govern our relationship with SeaSpine following the Separation. If we are required to indemnify SeaSpine for certain liabilities and related losses arising in connection with any of these agreements or if SeaSpine is required to indemnify us for certain liabilities and related losses arising in connection with any of these agreements and does not fulfill its obligations to us, we may be subject to substantial liabilities, which could have a material adverse effect on our financial position.
36

Table of Contents
If there is a determination that the spin-off is taxable for U.S. federal income tax purposes, then we and our stockholders that are subject to U.S. federal income tax could incur significant U.S. federal income tax liabilities and, in certain circumstances, we could be required to indemnify SeaSpine for material taxes pursuant to indemnification obligations under the tax matters agreement.
We received an opinion of Latham & Watkins LLP, tax counsel to us (the “Tax Opinion”), substantially to the effect that (i) the contribution of the stock of SeaSpine Orthopedics Corporation to SeaSpine, together with the internal distribution of the stock of SeaSpine to Integra (collectively, the “internal distribution”), will constitute a reorganization under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) the contribution of cash from us to SeaSpine (the “cash contribution”), together with the distribution of the stock of SeaSpine to our shareholders (the “distribution”), will constitute a reorganization under Sections 355 and 368(a)(1)(D) of the Code. Based on this tax treatment, the distribution will be tax-free to Integra and its stockholders for U.S. federal income tax purposes (except for any cash received in lieu of fractional shares). The Tax Opinion relied on certain facts, assumptions, representations and undertakings from us and SeaSpine regarding the past and future conduct of the companies’ respective businesses and other matters. The Tax Opinion is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Notwithstanding the opinion, the IRS could determine on audit that the internal distribution, the cash contribution and the distribution should be treated as taxable transactions if it determines that any of the facts, assumptions, representations or undertakings we or SeaSpine have made is not correct or has been violated, or that the internal distribution, the cash contribution and the distribution should be taxable for other reasons, including as a result of a significant change in stock or asset ownership after the distribution. If the distribution ultimately is determined to be taxable, the distribution could be treated as a taxable dividend or capital gain to you for U.S. federal income tax purposes, and you could incur significant U.S. federal income tax liabilities. In addition, we would recognize gain in an amount equal to the excess of the fair market value of shares of SeaSpine common stock distributed to our stockholders on the distribution date over our tax basis in such shares of SeaSpine common stock. Moreover, we could incur significant U.S. federal income tax liabilities if it is ultimately determined that the internal distribution does not qualify as a transaction that is tax-free for U.S. federal income tax purposes.
We might not be able to engage in desirable strategic transactions and equity issuances following the spin-off because of certain restrictions relating to requirements for tax-free distributions.
Our ability to engage in significant equity transactions could be limited or restricted after the spin-off in order to preserve, for U.S. federal income tax purposes, the tax-free nature of the internal distribution and the distribution. Even if the internal distribution and the distribution otherwise qualify for tax-free treatment under Section 355 of the Code, they may result in corporate-level taxable gain to us under Section 355(e) of the Code if there is a 50% or greater change in ownership, by vote or value, of shares of our stock or SeaSpine’s stock occurring as part of a plan or series of related transactions that includes the internal distribution or the distribution. Any acquisitions or issuances of our stock or SeaSpine’s stock within two years after the distribution are generally presumed to be part of such a plan, although we or SeaSpine may be able to rebut that presumption.
We will be subject to continuing contingent liabilities of SeaSpine following the spin-off.
After the Separation, there will be several significant areas where the liabilities of SeaSpine may become our obligations. For example, under the Code and the related rules and regulations, each corporation that was a member of our consolidated U.S. federal income tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the spin-off is jointly and severally liable for the U.S. federal income tax liability of the entire consolidated tax reporting group for that taxable period. If SeaSpine is unable to pay any prior period taxes for which it is responsible, we could be required to pay the entire amount of such taxes.
We are subject to stringent domestic and foreign medical device regulation and any adverse regulatory action may materially adversely affect our financial condition and business operations.
Our products, development activities and manufacturing processes are subject to extensive and rigorous regulation by numerous government agencies, including the FDA and comparable foreign agencies. To varying degrees, each of these agencies monitors and enforces our compliance with laws and regulations governing the development, testing, manufacturing, labeling, marketing and distribution of our medical devices. The process of obtaining marketing approval or clearance from the FDA and comparable foreign regulatory agencies for new products, or for enhancements or modifications to existing products, could

• | take a significant amount of time;

• | require the expenditure of substantial financial and other resources;

• | involve rigorous and expensive pre-clinical and clinical testing, as well as increased post-market surveillance;

• | involve modifications, repairs or replacements of our products; and

37

Table of Contents

• | result in limitations on the indicated uses of our products.

We cannot be certain that we will receive required approval or clearance from the FDA and foreign regulatory agencies for new products or modifications to existing products on a timely basis. The failure to receive approval or clearance for significant new products or modifications to existing products on a timely basis could have a material adverse effect on our financial condition and results of operations.
Both before and after a product is commercially released, we have ongoing responsibilities under FDA regulations. For example, we are required to comply with the FDA's Quality System Regulation, which mandates that manufacturers of medical devices adhere to certain quality assurance requirements pertaining to, among other things, validation of manufacturing processes, controls for purchasing product components, and documentation practices. As another example, the Federal Medical Device Reporting regulation requires us to provide information to the FDA whenever there is evidence that reasonably suggests that a device may have caused or contributed to a death or serious injury or, that a malfunction occurred which would be likely to cause or contribute to a death or serious injury upon recurrence. Compliance with applicable regulatory requirements is subject to continual review and is monitored rigorously through periodic inspections by the FDA, which may result in observations on Form 483, and in some cases warning letters, that require corrective action. If the FDA were to conclude that we are not in compliance with applicable laws or regulations, or that any of our medical devices are ineffective or pose an unreasonable health risk, the FDA could ban such medical devices, detain or seize such medical devices, order a recall, repair, replacement, or refund of such devices, or require us to notify health professionals and others that the devices present unreasonable risks of substantial harm to the public health.
The FDA has been increasing its scrutiny of the medical device industry and the government is expected to continue to scrutinize the industry closely with inspections, and possibly enforcement actions, by the FDA or other agencies. Additionally, the FDA may restrict manufacturing and impose other operating restrictions, enjoin and restrain certain violations of applicable law pertaining to medical devices, and assess civil or criminal penalties against our officers, employees, or us. The FDA may also recommend prosecution to the Department of Justice. Any adverse regulatory action, depending on its magnitude, may restrict us from effectively manufacturing, marketing and selling our products. In addition, negative publicity and product liability claims resulting from any adverse regulatory action could have a material adverse effect on our financial condition and results of operations.
We have an outstanding FDA warning letter related to TEI Biosciences Inc. ("TEI"), a recent acquisition 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. 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 regarding TEI's or our products and require additional corrective actions.
While we have taken measures to enhance our Quality System, we cannot assure you that future inspections by the FDA and the standards they apply will not result in warning letters for any facility in the future.
The FDA Safety and Innovation Act ("FDASIA"), which includes the Medical Device User Fee Amendments of 2012 ("MDUFA III"), as well as other medical device provisions, went into effect October 1, 2012. This includes performance goals and user fees paid to the FDA by medical device companies when they register and list with the FDA and when they submit an application to market a device in the U.S. This will affect the fees paid to the FDA over the five-year period that FDASIA is in effect. As part of FDASIA, there are additional requirements regarding the FDA Establishment Registration and Listing of Medical Devices. All U.S. and foreign manufacturers must register and list medical devices for sale in the U.S. All of our facilities comply with these requirements. That said, we also source products from foreign contract manufacturers. From this business practice, it is possible that some of our foreign contract manufacturers will not comply with these requirements and choose not to register with the FDA. In such an event, we will need to determine if there are alternative foreign contract manufacturers who comply with the FDA Establishment Registration requirements. If such a foreign contract manufacturer is a sole supplier of one of our products, there is a risk that we may not be able to source another supplier.
The FDA issued a final rule on September 24, 2013 to establish a system to adequately identify devices through distribution and use. This rule requires the label of medical devices to include a unique device identifier (“UDI”), except where the rule provides for an exception or alternative placement. The labeler must submit product information concerning devices to FDA's Global Unique Device Identification Database ("GUDID"), unless subject to an exception or alternative. The system established by this rule requires the label and device package of each medical device to include a UDI and requires that each UDI be provided in a plain-text version and in a form that uses automatic identification and data capture technology. If the device is intended to be used more than once and intended to be reprocessed before each use, then there is a requirement for the UDI to be directly marked on the
38

Table of Contents
device itself. This regulation will require significant resources and expense to comply with the regulation. We have complied with the initial requirements of this regulation for our Class III products by meeting the September 2014 deadline for labeling and entering the data in FDA's GUDID Database.
Finally, the FDA issued regulations regarding “Current Good Manufacturing Practice Requirements for Combination Products” on January 22, 2013. These regulations apply to some of our product lines that have been designated by the FDA as Combination Products. There have been and will be additional costs associated with compliance with the FDA Good Manufacturing Practice Requirements regulations for Combination Products.
We manufacture medical devices that are subject to various electrical safety standards. Many countries have adopted the recommendations of the International Electrotechnical Commission (“IEC”) for the safety and effectiveness of medical electrical equipment. The IEC is a non-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies. Their updated standards were implemented in some markets starting in July 2012 and have continued to be adopted over the following years worldwide. If we cannot comply with these standards, we may not be able to sell some of our products in the affected markets. Most of our affected products have already been modified to meet these standards and are substantially in compliance with these standards. Except in limited circumstances, we do not anticipate any delays in selling our products in the markets that have adopted the IEC updated standards.
In addition, the FDCA permits device manufacturers to promote products solely for the uses and indications set forth in the approved product labeling. A number of enforcement actions have been taken against manufacturers that promote products for “off-label” uses, including actions alleging that federal health care program reimbursement of products promoted for "off-label" uses are false and fraudulent claims to the government. The failure to comply with “off-label” promotion restrictions can result in significant financial penalties and a required corporate integrity agreement with the federal government imposing significant administrative obligations and costs, and potential evaluation from federal health care programs.
Foreign governmental regulations have become increasingly stringent and more common, and we may become subject to even more rigorous regulation by foreign governmental authorities in the future. Penalties for a company's noncompliance with foreign governmental regulation could be severe, including revocation or suspension of a company's business license and criminal sanctions. Any domestic or foreign governmental medical device law or regulation imposed in the future may have a material adverse effect on our financial condition and business operations.
Certain of our products contain materials derived from animal sources and may become subject to additional regulation.
Certain of our products, including our dermal regeneration products, duraplasty products, biomaterial products for the spine, nerve and tendon repair products, wound care products and certain other products, contain material derived from bovine tissue. In 2014 approximately 23% of our revenues were attributable to products containing material derived from bovine tissue. Products that contain materials derived from animal sources, including food, pharmaceuticals and medical devices, are subject to scrutiny in the media and by regulatory authorities. Regulatory authorities are concerned about the potential for the transmission of disease from animals to humans via those materials. This public scrutiny has been particularly acute in Japan and Western Europe with respect to products derived from animal sources, because of concern that materials infected with the agent that causes bovine spongiform encephalopathy, otherwise known as BSE or mad cow disease, may, if ingested or implanted, cause a variant of the human Creutzfeldt-Jakob Disease, an ultimately fatal disease with no known cure. In 2013, the World Organization for Animal Health ("OIE") recommended that the United States risk classification for BSE be upgraded from controlled risk to negligible risk.
We take care to provide that our products are safe and free of agents that can cause disease. In particular, we have qualified a source of collagen from a country outside the United States that is considered BSE-free. The World Health Organization classifies different types of cattle tissue for relative risk of BSE transmission. Deep flexor tendon and bovine fetal skin, which are used in our products, are in the lowest-risk categories for BSE transmission (the same category as milk, for example), and are therefore considered to have a negligible risk of containing the agent that causes BSE (an improperly folded protein known as a prion). Nevertheless, products that contain materials derived from animals, including our products, could become subject to additional regulation, or even be banned in certain countries, because of concern over the potential for the transmission of prions. Significant new regulation, or a ban of our products, could have a material adverse effect on our current business or our ability to expand our business.
Certain countries, such as Japan, China, Taiwan and Argentina, have issued regulations that require our collagen products be sourced from countries where no cases of BSE have occurred, and the EU has requested that our dural replacement products and other products that are used in neurological tissue be sourced from a country where no cases of BSE have occurred. Currently, we source bovine fetal hides from the United States and purchase tendon from the United States and New Zealand. New Zealand has

never had a case of BSE. We received approval in the United States, the EU, Japan, Taiwan, China, Argentina as well as other countries for the use of New Zealand-sourced tendon in the manufacturing of our products. If we cannot continue to use or qualify a source of tendon from New Zealand or another country that has never had a case of BSE, we will not be permitted to sell our collagen products in certain countries.
Certain of our products are derived from human tissue and are subject to additional regulations and requirements.
We distribute medical devices derived from human tissue. The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. Examples include bone, ligament, skin and cornea.
Some HCT/Ps also meet the definition of a biological product, medical device or drug regulated under the FD&C Act. Section 361 of the PHSA authorizes the FDA to issue regulations to prevent the introduction, transmission or spread of communicable disease. HCT/Ps regulated as “361” HCT/Ps are subject to requirements relating to registering facilities and listing products with FDA, screening and testing for tissue donor eligibility, Good Tissue Practice, or GTP, when processing, storing, labeling, and distribution HCT/Ps, including required labeling information, stringent record keeping; and adverse event reporting. These biologic, device or drug HCT/Ps must comply both with the requirements exclusively applicable to 361 HCT/Ps and, in addition, with requirements applicable to biologics, devices or drugs, including premarket clearance or approval.
It could be difficult to replace some of our suppliers.
Outside vendors, some of whom are sole-source suppliers, provide key components and raw materials used in the manufacture of our products. Although we believe that alternative sources for many of these components and raw materials are available, any interruption in supply of a limited or sole-source component or raw material could harm our ability to manufacture our products until a new or alternative source of supply is identified and qualified. In addition, an uncorrected defect or supplier’s variation in a component or raw material, either unknown to us or incompatible with our manufacturing process, could harm our ability to manufacture products. We may not be able to find a sufficient alternative supplier in a reasonable time period, or on commercially reasonable terms, if at all, and our ability to produce and supply our products could be impaired. We believe that these factors are most likely to affect the following products that we manufacture:

• | our collagen-based products, such as the Integra® Dermal Regeneration Template and wound matrix products, the DuraGen® family of products, and our Absorbable Collagen Sponges;

• | our products made from silicone, such as our neurosurgical shunts and drainage systems and hemodynamic shunts;

• | products which use many different specialty parts from numerous suppliers, such as our intracranial monitors, catheters and headlights; and

• | products that use pyrolytic carbon (i.e., PyroCarbon) technology, such as certain of our reconstructive extremity orthopedic implants.

In connection with our Confluent Surgical acquisition in January 2014, we entered into a multi-year supply agreement with an affiliate of the seller to continue to manufacture the acquired surgical sealant and adhesion barrier product lines and recently entered into a contract with a third-party to assume the manufacture of these product lines after the relationship with the affiliate of the seller concludes in several years.
If we were suddenly unable to purchase products from one or more of these companies, we would need a significant period of time to qualify a replacement, and the production of any affected products could be disrupted.
While it is our policy to maintain sufficient inventory of components so that our production will not be significantly disrupted even if a particular component or material is not available for a period of time, we remain at risk that we will not be able to qualify new components or materials quickly enough to prevent a disruption if one or more of our suppliers ceases production of important components or materials.
We may experience difficulties, delays, performance impact or unexpected costs from consolidation of facilities.
We consolidated several facilities in 2014 and 2015, and could further consolidate our operations in the future in order to improve our cost structure, achieve increased operating efficiencies, and improve our competitive standing or results of operations and/or to address unfavorable economic conditions. We may further reduce staff, make changes to certain capital projects, close certain production operations and abandon leases for certain facilities that will not be used in our operations. As part of these initiatives, we may also lose favorable tax incentives or not be able to renew leases on acceptable terms. In conjunction with any actions, we will continue to make significant investments and build the framework for our future growth. However, we may not realize, in

full or in part, the anticipated benefits and savings from these efforts because of unforeseen difficulties, delays, implementation issues or unexpected costs. If we are unable to achieve or maintain all of the resulting savings or benefits to our business or other unforeseen events occur, our business and results of operations may be adversely affected.
