Summary Of Significant Accounting Policies [Abstract] |
Summary Of Significant Accounting Policies | 1. Summary of Significant Accounting Policies ﻿ Nature of Business ﻿ CryoLife, Inc. (“CryoLife,” the “Company,” “we,” or “us”), incorporated in 1984 in Florida, is a leader in medical device manufacturing, processing, and distribution of medical devices and implantable human tissues used in cardiac surgical procedures. CryoLife’s medical devices include: BioGlue® Surgical Adhesive (“BioGlue”); BioFoam® Surgical Matrix (“BioFoam”); On-X valves and surgical products; the CardioGenesis cardiac laser therapy product line, which includes a laser console system and single-use, fiber-optic handpieces, that are used for the treatment of coronary artery disease in patients with severe angina; PerClot®, an absorbable powdered hemostat, which the Company distributes internationally for Starch Medical, Inc. (“SMI”); and PhotoFix TM, a bovine pericardial patch stabilized using a dye-mediated photo-fixation process that requires no glutaraldehyde. The cardiac and vascular human tissues distributed by CryoLife include the CryoValve® SG pulmonary heart valve (“CryoValve SGPV”) and the CryoPatch® SG pulmonary cardiac patch (“CryoPatch SG”), both of which are processed using CryoLife’s proprietary SynerGraft® technology. ﻿ Principles of Consolidation ﻿ The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. ﻿ Translation of Foreign Currencies ﻿ The Company’s revenues and expenses transacted in foreign currencies are translated as they occur at exchange rates in effect at the time of each transaction. Realized gains and losses on foreign currency transactions are recorded as a component of other (income) expense, net on the Company’s Consolidated Statements of Operations and Comprehensive Income. Assets and liabilities of the Company denominated in foreign currencies are translated at the exchange rate in effect as of the balance sheet date and are recorded as a separate component of accumulated other comprehensive income (loss) in the shareholders' equity section of the Company’s Consolidated Balance Sheets. ﻿ Use of Estimates ﻿ The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Estimates and assumptions are used when accounting for investments, allowance for doubtful accounts, inventory, deferred preservation costs, acquired assets or businesses, long‑lived tangible and intangible assets, deferred income taxes, commitments and contingencies (including product and tissue processing liability claims, claims incurred but not reported, and amounts recoverable from insurance companies), stock-based compensation, certain accrued liabilities (including accrued procurement fees, income taxes, and financial instruments), contingent consideration liability, and other items as appropriate. ﻿ Revenue Recognition ﻿ Revenues for products, including: BioGlue, BioFoam, On-X products, CardioGenesis cardiac laser therapy handpieces and accessories, PerClot, PhotoFix, and other medical devices, are typically recognized at the time the product is shipped, at which time title passes to the customer, and there are no further performance obligations. Revenues from consignment are recognized when the medical device is implanted. The Company recognizes revenues for preservation services when services are completed and tissue is shipped to the customer. Revenues from upfront licensing agreements are recognized ratably over the period the Company expects to fulfill its obligations. ﻿ Revenues from the sale of laser consoles are considered multiple element arrangements, and such revenues are allocated to the elements of the sale. The Company allocates revenues based primarily on the revenue these individual elements would generate if sold separately. Revenues from the sales of domestic laser consoles are typically recognized when the laser is installed at a customer site and all materials for the laser console’s use are delivered. Revenues from the sales of laser consoles to international distributors are evaluated individually based on the terms of the sale and collectability to determine when revenue has been earned and can be recognized. ﻿ Shipping and Handling Charges ﻿ Fees charged to customers for shipping and handling of products and tissues are included in product revenues and preservation services revenues, respectively. The costs for shipping and handling of products and tissues are included as a component of cost of products and cost of preservation services, respectively. ﻿ Advertising Costs ﻿ The costs to develop, produce, and communicate the Company’s advertising are expensed as incurred and are classified as general, administrative, and marketing expenses. The Company records the cost to print or copy certain sales materials as a prepaid expense and amortizes these costs as an advertising expense over the period they are expected to be used, typically six months to one year. The total amount of advertising expense included in the Company’s Consolidated Statements of Operations and Comprehensive Income was $384,000, $521,000, and $821,000 for the years ended December 31, 2016, 2015, and 2014, respectively. ﻿ Stock‑Based Compensation ﻿ The Company has stock option and stock incentive plans for employees and non-employee Directors that provide for grants of restricted stock awards (“RSA”s), performance stock awards (“PSA”s), restricted stock units (“RSU”s), performance stock units (“PSU”s), and options to purchase shares of CryoLife common stock at exercise prices generally equal to the fair values of such stock at the dates of grant. The Company also maintains a shareholder approved Employee Stock Purchase Plan (the “ESPP”) for the benefit of its employees. The ESPP allows eligible employees the right to purchase common stock on a regular basis at the lower of 85% of the market price at the beginning or end of each offering period. The RSAs, PSAs, RSUs, PSUs, and stock options granted by the Company typically vest over a one to three-year period. The stock options granted by the Company typically expire within seven years of the grant date. ﻿ The Company values its RSAs, PSAs, RSUs, and PSUs based on the stock price on the date of grant. The Company expenses the related compensation cost of RSAs, PSAs, and RSUs using the straight-line method over the vesting period. The Company expenses the related compensation cost of PSUs based on the number of shares expected to be issued if achievement of the performance component is probable using a straight-line method over each vesting tranche of the award. The amount of compensation costs expensed related to PSUs is adjusted as needed if the Company deems that achievement of the performance component is no longer probable, or if the Company’s expectation of the number of shares to be issued changes. The Company uses a Black-Scholes model to value its stock option grants and expenses the related compensation cost using the straight-line method over the vesting period. The fair value of the Company’s ESPP options is also determined using a Black-Scholes model and is expensed over the vesting period. ﻿ The fair value of stock options and ESPP options is determined on the grant date using assumptions for the expected term, volatility, dividend yield, and the risk-free interest rate. The expected term is primarily based on the contractual term of the option and Company data related to historic exercise and post-vesting forfeiture patterns, which is adjusted based on management’s expectations of future results. The Company’s anticipated volatility level is primarily based on the historic volatility of the Company’s common stock, adjusted to remove the effects of certain periods of unusual volatility not expected to recur, and adjusted based on management’s expectations of future volatility, for the life of the option or option group. The Company’s model included a zero dividend yield assumption when the Company’s quarterly dividends were discontinued after the fourth quarter of 2015. The risk-free interest rate is based on recent U.S. Treasury note auction results with a similar life to that of the option. The Company’s model does not include a discount for post-vesting restrictions, as the Company has not issued awards with such restrictions. ﻿ The period expense for the Company’s stock compensation is determined based on the valuations discussed above and, at that time, an estimated forfeiture rate is used to reduce the expense recorded. The Company’s estimate of pre-vesting forfeitures is primarily based on the recent historical experience of the Company and is later adjusted to reflect actual forfeitures. ﻿ Income Per Common Share ﻿ Income per common share is computed using the two class method, which requires the Company to include unvested RSAs and PSAs that contain non-forfeitable rights to dividends (whether paid or unpaid) as participating securities in the income per common share calculation. ﻿ Under the two class method, net income is allocated to the weighted-average number of common shares outstanding during the period and the weighted-average participating securities outstanding during the period. The portion of net income that is allocated to the participating securities is excluded from basic and dilutive net income per common share. Diluted net income per share is computed using the weighted-average number of common shares outstanding plus the dilutive effects of outstanding stock options and awards and other dilutive instruments as appropriate. ﻿ Dividends Cash dividends approved by the Company’s Board of Directors were paid every three months in the amount of $0.0275 per share in the first quarter of 2014 and $0.03 in the remainder of 2014 and in 2015. In December 2015 the Board of Directors undertook a review of the Company’s dividend policy and determined that it would be in the best interest of the shareholders to discontinue dividend payments for the foreseeable future. The Company did not pay quarterly dividends in 2016 and does not currently anticipate paying out further quarterly dividends. ﻿ Financial Instruments ﻿ The Company’s financial instruments include cash equivalents, marketable securities, restricted securities, accounts receivable, notes receivable, accounts payable, debt obligations, contingent consideration, and derivatives. The Company typically values financial assets and liabilities such as receivables, accounts payable, and debt obligations at their carrying values, which approximate fair value due to their generally short-term duration. Other financial instruments are recorded as discussed in the sections below. ﻿ Fair Value Measurements ﻿ The Company records certain financial instruments at fair value, including: cash equivalents, certain marketable securities, certain restricted securities, contingent consideration, and derivative instruments. The Company may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2016 the Company has not chosen to make any such elections. Fair value financial instruments are recorded in accordance with the fair value measurement framework. ﻿ The Company also measures certain non-financial assets at fair value on a non-recurring basis. These non-recurring valuations include evaluating assets such as cost method investments, long‑lived assets, and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group; applying accounting for business combinations; and allocating goodwill to divested components of a business. The Company uses the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down. ﻿ The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels. These levels from highest to lowest priority are as follows: ﻿
| · |  | Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;
| · |  | Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data; and
| · |  | Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.
The determination of fair value and the assessment of a measurement’s placement within the hierarchy requires judgment. Level 3 valuations often involve a higher degree of judgment and complexity. Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions. Management’s assumptions could vary depending on the asset or liability valued and the valuation method used. Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods. The Company may also engage external advisors to assist in determining fair value, as appropriate. ﻿ Although the Company believes that the recorded fair value of its financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values. ﻿ Cash and Cash Equivalents ﻿ Cash equivalents consist primarily of highly liquid investments with maturity dates of three months or less at the time of acquisition. The carrying value of cash equivalents approximates fair value. ﻿ Cash Flow Supplemental Disclosures ﻿ Supplemental disclosures of cash flow information for the years ended December 31 (in thousands):

﻿ Marketable Securities and Other Investments ﻿ The Company typically invests its excess cash for short-term periods in large, well‑capitalized financial institutions, and the Company's policy excludes investment in any securities rated less than "investment‑grade" by national rating services, unless specifically approved by the Board of Directors. The Company sometimes makes longer term strategic investments in medical device companies, and these investments must be approved by the Board of Directors. ﻿ The Company determines the classification of its investments as trading, available-for-sale, or held-to-maturity at the time of purchase and reevaluates such designations quarterly. Trading securities are securities that are acquired principally for the purpose of generating a profit from short-term fluctuations in price. Debt securities are classified as held‑to‑maturity when the Company has the intent and ability to hold the securities to maturity. Any securities not designated as trading or held‑to‑maturity are considered available-for-sale. The Company typically states its investments at their fair values; however, for held‑to‑maturity securities or when current fair value information is not readily available, investments are recorded using the cost method. The cost of securities sold is based on the specific identification method. ﻿ Under the fair value method, the Company adjusts each investment to its market price and records the unrealized gains or losses in other (income) expense, net for trading securities, or accumulated other comprehensive income (loss), for available-for-sale securities. Interest, dividends, realized gains and losses, and declines in value judged to be other than temporary are included in other (income) expense, net. Under the cost method, investments are recorded at cost, with subsequent dividends received recognized as income. Cost method investments are reviewed for impairment if factors indicate that a decrease in the value of the investment has occurred. ﻿ The Company reviews its contracts to determine if they require any restrictions to cash or investments. If there is a contractual agreement restricting the availability of the Company’s cash or investments, the Company will classify these amounts as current or long-term restricted cash or investments. ﻿ Accounts and Notes Receivable and Allowance for Doubtful Accounts ﻿ The Company’s accounts receivable are primarily from hospitals and distributors that either use or distribute the Company’s products and tissues. The Company assesses the likelihood of collection based on a number of factors, including past transaction history and the credit worthiness of the customer, as well as the increased risks related to international customers and large distributors. The Company determines the allowance for doubtful accounts based upon specific reserves for known collection issues, as well as a non-specific reserve based upon aging buckets. The Company charges off uncollectable amounts against the reserve in the period in which it determines they are uncollectible. The Company’s accounts receivable balances were reported net of allowance for doubtful accounts of $503,000 and $232,000 as of December 31, 2016 and 2015, respectively. ﻿ The Company may lend money from time-to-time through a note receivable, which may be made in conjunction with a longer term strategic investment in a medical device company, as approved by the Board of Directors. The Company assesses the likelihood of collection of its notes receivable based on a number of factors, including past transaction history, credit worthiness, and the liquidity position of the recipient as well as the expected value of any collateral. The Company’s notes receivable balance was zero as of December 31, 2016 and 2015, respectively. See Note 8 for further discussion of the Company’s note receivable from ValveXchange, Inc. (“ValveXchange”). ﻿ Inventories ﻿ Inventories are comprised of BioGlue; BioFoam; On-X; PerClot; CardioGenesis cardiac laser therapy laser consoles, handpieces, and accessories; PhotoFix; other medical devices; supplies; and raw materials. In 2015, inventories also included HeRO Grafts and ProCol. Inventories are valued at the lower of cost or market on a first‑in, first‑out basis. Typcially, upon shipment, or upon implant of a medical device on consignment, revenue is recognized and the related inventory costs are expensed as cost of products. Cost of products also includes, as applicable, lower of cost or market write-downs and impairments for products not deemed to be recoverable and, as incurred, idle facility expense, excessive spoilage, extra freight, and rehandling costs. ﻿ Inventory costs for manufactured products consist primarily of direct labor and materials (including salary and fringe benefits, raw materials, and supplies) and indirect costs (including allocations of costs from departments that support manufacturing activities and facility allocations). The allocation of fixed production overhead costs is based on actual production levels, to the extent that they are within the range of the facility’s normal capacity. Inventory costs for products purchased for resale or manufactured under contract consist primarily of the purchase cost, freight-in charges, and indirect costs as appropriate. ﻿ The Company regularly evaluates its inventory to determine if the costs are appropriately recorded at the lower of cost or market value. The Company also evaluates its inventory for costs not deemed to be recoverable, including inventory not expected to ship prior to its expiration. Lower of cost or market value write-downs are recorded if the book value exceeds the estimated market value of the inventory, based on recent sales prices at the time of the evaluation. Impairment write-downs are recorded based on the book value of inventory deemed to be impaired. Actual results may differ from these estimates. Write-downs of inventory are expensed as cost of products, and these write-downs are permanent impairments that create a new cost basis, which cannot be restored to its previous levels if the Company’s estimates change. ﻿ The Company recorded write-downs to its inventory totaling $467,000, $858,000, and $140,000 for the years ended December 31, 2016, 2015, and 2014, respectively. The 2015 write-down is primarily related to the write-down of PerClot Topical inventory following the Company’s cessation of marketing, sales, and distribution of PerClot Topical in the U.S. See Note 9 for further discussion of PerClot Topical. ﻿ Deferred Preservation Costs ﻿ Deferred preservation costs includes costs of cardiac and vascular tissues available for shipment, tissues currently in active processing, and tissues held in quarantine pending release to implantable status. By federal law, human tissues cannot be bought or sold; therefore, the tissues the Company preserves are not held as inventory. The costs the Company incurs to procure and process cardiac and vascular tissues are instead accumulated and deferred. Deferred preservation costs are stated at the lower of cost or market value on a first‑in, first‑out basis and are deferred until revenue is recognized. Upon shipment of tissue to an implanting facility, revenue is recognized and the related deferred preservation costs are expensed as cost of preservation services. Cost of preservation services also includes, as applicable, lower of cost or market write-downs and impairments for tissues not deemed to be recoverable, and includes, as incurred, idle facility expense, excessive spoilage, extra freight, and rehandling costs. ﻿ The calculation of deferred preservation costs involves judgment and complexity and uses the same principles as inventory costing. Donated human tissue is procured from deceased human donors by organ and tissue procurement organizations (“OTPOs”), which consign the tissue to the Company for processing, preservation, and distribution. Deferred preservation costs consist primarily of the procurement fees charged by the OTPOs, direct labor and materials (including salary and fringe benefits, laboratory supplies and expenses, and freight‑in charges), and indirect costs (including allocations of costs from support departments and facility allocations). Fixed production overhead costs are allocated based on actual tissue processing levels, to the extent that they are within the range of the facility’s normal capacity. ﻿ These costs are then allocated among the tissues processed during the period based on cost drivers, such as the number of donors or number of tissues processed. The Company applies a yield estimate to all tissues in process and in quarantine to estimate the portion of tissues that will ultimately become implantable. Management estimates quarantine yields based on its experience and reevaluates these estimates periodically. Actual yields could differ significantly from the Company’s estimates, which could result in a change in tissues available for shipment, and could increase or decrease the balance of deferred preservation costs. These changes could result in additional cost of preservation services expense or could increase per tissue preservation costs, which would impact gross margins on tissue preservation services in future periods. ﻿ The Company regularly evaluates its deferred preservation costs to determine if the costs are appropriately recorded at the lower of cost or market value. The Company also evaluates its deferred preservation costs for costs not deemed to be recoverable, including tissues not expected to ship prior to the expiration date of their packaging. Lower of cost or market value write-downs are recorded if the tissue processing costs incurred exceed the estimated market value of the tissue services, based on recent average service fees at the time of the evaluation. Impairment write-downs are recorded based on the book value of tissues deemed to be impaired. Actual results may differ from these estimates. Write-downs of deferred preservation costs are expensed as cost of preservation services, and these write-downs are permanent impairments that create a new cost basis, which cannot be restored to its previous levels if the Company’s estimates change. ﻿ The Company recorded write-downs to its deferred preservation costs totaling $897,000, $483,000, and $540,000 for the years ended December 31, 2016, 2015, and 2014, respectively, due primarily to tissues not expected to ship prior to the expiration date of the packaging. ﻿ Property and Equipment ﻿ Property and equipment is stated at cost. Depreciation is provided over the estimated useful lives of the assets, generally three to ten years, on a straight‑line basis. Leasehold improvements are amortized on a straight‑line basis over the remaining lease term at the time the assets are capitalized or the estimated useful lives of the assets, whichever is shorter. ﻿ Depreciation expense for the years ended December 31 is as follows (in thousands):
﻿ |  |  |  |  |  |  |  |
﻿ |  |  |  |  |  |  |  |
﻿ | 2016 |  | 2015 |  | 2014
﻿Depreciation expense | $ | 3,958 |  | $ | 3,728 |  | $ | 4,001
﻿ Goodwill and Other Intangible Assets ﻿ The Company’s intangible assets consist of goodwill, patents, trademarks, and other intangible assets, as discussed in Note 11. The Company’s goodwill is attributable to a segment or segments of the Company’s business, as appropriate, as the related acquired business that generated the goodwill is integrated into the Company’s operations. Upon divestiture of a component of the Company’s business, the goodwill related to the operating segment is allocated to the divested business using the relative fair value allocation method. ﻿ The Company amortizes its definite lived intangible assets over their expected useful lives using the straight-line method, which the Company believes approximates the period of economic benefits of the related assets. The Company’s indefinite lived intangible assets do not amortize, but are instead subject to periodic impairment testing as discussed in “Impairments of Long-Lived Assets and Non-Amortizing Intangible Assets” below. ﻿ Impairments of Long‑Lived Assets and Non-Amortizing Intangible Assets ﻿ The Company assesses the potential impairment of its long-lived assets to be held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that could trigger an impairment review include, but are not limited to, the following: ﻿
| · |  | Significant underperformance relative to expected historical or projected future operating results;
| · |  | Significant negative industry or economic trends;
| · |  | Significant decline in the Company’s stock price for a sustained period; or
| · |  | Significant decline in the Company’s market capitalization relative to net book value.
﻿ If CryoLife determines that an impairment review is necessary, the Company will evaluate its assets or asset groups by comparing their carrying values to the sum of the undiscounted future cash flows expected to result from their use and eventual disposition. If the carrying values exceed the future cash flows, then the asset or asset group is considered impaired, and the Company will write down the value of the asset or asset group. For the years ended December 31, 2016, 2015, and 2014 the Company did not experience any factors that indicated that an impairment review of its long-lived assets was warranted. ﻿ CryoLife evaluates its goodwill and other non-amortizing intangible assets for impairment on an annual basis as of October 31 and, if necessary, during interim periods if factors indicate that an impairment review is warranted. As of October 31, 2016 the Company’s non-amortizing intangible assets consisted of goodwill, acquired procurement contracts and agreements, trademarks, and other acquired technology. The Company performed an analysis of its non-amortizing intangible assets as of October 31, 2016 and 2015, and determined that the fair value of the assets and the fair value of the reporting unit exceeded their associated carrying values and were, therefore, not impaired. Management will continue to evaluate the recoverability of these non-amortizing intangible assets. ﻿ Accrued Procurement Fees ﻿ Donated tissue is procured from deceased human donors by OTPOs, which consign the tissue to the Company for processing, preservation, and distribution. The Company reimburses the OTPOs for their costs to recover the tissue and includes these costs as part of deferred preservation costs, as discussed above. The Company accrues estimated procurement fees due to the OTPOs at the time tissues are received based on contractual agreements between the Company and the OTPOs. ﻿ Leases ﻿ The Company has operating lease obligations resulting from the lease of land and buildings that comprise the Company's corporate headquarters and manufacturing facilities; leases related to additional manufacturing, office, and warehouse space; leases on Company vehicles; and leases on a variety of office equipment, as discussed in Note 14. Certain of the Company’s leases contain escalation clauses, rent concessions, and renewal options for additional periods. Rent expense is computed on the straight‑line method over the lease term and the related liability is recorded as deferred rent obligations on the Company’s Consolidated Balance Sheets. ﻿ Debt Issuance Costs ﻿ Debt issuance costs related to the Company’s term loan and line of credit are capitalized and reported net of the current and long-term debt or as a prepaid asset when there are no outstanding borrowings. The Company amortizes debt issuance costs to interest expense on its term loan using the effective interest method over the life of the debt agreement. The Company amortizes debt issuance costs to interest expense on its line of credit on a straight line basis over the life of the debt agreement. ﻿ Liability Claims ﻿ In the normal course of business, the Company is made aware of adverse events involving its products and tissues. Future adverse events could ultimately give rise to a lawsuit against the Company, and liability claims may be asserted against the Company in the future based on past events it is not aware of at the present time. The Company maintains claims‑made insurance policies to mitigate its financial exposure to product and tissue processing liability claims. Claims‑made insurance policies generally cover only those asserted claims and incidents that are reported to the insurance carrier while the policy is in effect. Thus, a claims‑made policy does not generally represent a transfer of risk for claims and incidents that have been incurred but not reported to the insurance carrier during the policy period. Any punitive damage components of claims are uninsured. ﻿ The Company engages external advisors to assist it in estimating its liability and any related recoverable under the Company's insurance policies as of each balance sheet date. The Company uses a frequency‑severity approach to estimate its unreported product and tissue processing liability claims, whereby projected losses are calculated by multiplying the estimated number of claims by the estimated average cost per claim. The estimated claims are determined based on the reported claim development method and the Bornhuetter‑Ferguson method using a blend of the Company's historical claim experience and industry data. The estimated cost per claim is calculated using a lognormal claims model blending the Company's historical average cost per claim with industry claims data. The Company uses a number of assumptions in order to estimate the unreported loss liability including: the future claim reporting time lag, the frequency of reported claims, the average cost per claim, and the maximum liability per claim. The Company believes that the assumptions it uses provide a reasonable basis for its calculation. However, the accuracy of the estimates is limited by various factors, including, but not limited to, Company specific conditions, uncertainties surrounding the assumptions used, and the scarcity of industry data directly relevant to the Company's business activities. Due to these factors, actual results may differ significantly from the Company’s assumptions and from the amounts accrued. ﻿ The Company accrues its estimate of unreported product and tissue processing liability claims as a component of other long‑term liabilities and records the related recoverable insurance amounts as a component of other long‑term assets. The amounts recorded represent management's estimate of the probable losses and anticipated recoveries for unreported claims related to products sold and services performed prior to the balance sheet date. ﻿ Legal Contingencies ﻿ The Company accrues losses from a legal contingency when the loss is both probable and reasonably estimable. The accuracy of the Company’s estimates of losses for legal contingencies is limited by uncertainties surrounding litigation. Therefore, actual results may differ significantly from the amounts accrued, if any. The Company accrues for legal contingencies as a component of accrued expenses and/or other long‑term liabilities. Gains from legal contingencies are recorded when the contingency is resolved. ﻿ Legal Fees ﻿ The Company expenses the costs of legal services, including legal services related to product and tissue processing liability claims and legal contingencies, as they are incurred. Reimbursement of legal fees by an insurance company or other third party is recorded as a reduction to legal expense. ﻿ Uncertain Tax Positions ﻿ The Company periodically assesses its uncertain tax positions and recognizes tax benefits if they are “more-likely-than-not” to be upheld upon review by the appropriate taxing authority. The Company measures the tax benefit by determining the maximum amount that has a “greater than 50 percent likelihood” of ultimately being realized. The Company reverses previously accrued liabilities for uncertain tax positions when audits are concluded, statutes expire, administrative practices dictate that a liability is no longer warranted, or in other circumstances as deemed necessary. These assessments can be complex and the Company often obtains assistance from external advisors to make these assessments. The Company recognizes interest and penalties related to uncertain tax positions in other (income) expense, net on its Consolidated Statements of Operations and Comprehensive Income. See Note 12 for further discussion of the Company’s liabilities for uncertain tax positions. ﻿ Deferred Income Taxes ﻿ Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax return purposes. The Company periodically assesses the recoverability of its deferred tax assets, as necessary, when the Company experiences changes that could materially affect its determination of the recoverability of its deferred tax assets. Management provides a valuation allowance against its deferred tax assets when, as a result of this analysis, management believes it is more likely than not that some portion or all of its deferred tax assets will not be realized. ﻿ Assessing the recoverability of deferred tax assets involves judgment and complexity. Estimates and judgments used in the determination of the need for a valuation allowance and in calculating the amount of a needed valuation allowance include, but are not limited to, the following: ﻿
| · |  | Projected future operating results;
| · |  | Anticipated future state tax apportionment;
| · |  | Timing and amounts of anticipated future taxable income;
| · |  | Timing of the anticipated reversal of book/tax temporary differences;
| · |  | Evaluation of statutory limits regarding usage of certain tax assets; and
| · |  | Evaluation of the statutory periods over which certain tax assets can be utilized.
﻿ Significant changes in the factors above, or other factors, could affect the Company’s ability to use its deferred tax assets. Such changes could have a material, adverse impact on the Company’s profitability, financial position, and cash flows. The Company will continue to assess the recoverability of its deferred tax assets, as necessary, when the Company experiences changes that could materially affect its prior determination of the recoverability of its deferred tax assets. ﻿ The Company believes that the realizability of its acquired net operating loss carryforwards will be limited in future periods due to a change in control of its former subsidiaries Hemosphere, Inc. (“Hemosphere”) and Cardiogenesis Corporation (“Cardiogenesis”), as mandated by Section 382 of the Internal Revenue Code of 1986, as amended. The Company believes that its acquisitions of these companies each constituted a change in control, and that prior to the Company’s acquisition, Hemosphere had experienced other equity ownership changes that should be considered a change in control. The Company also acquired net operating loss carryforwards in the acquisition of On-X Life Technologies that are limited under Section 382. However, the Company believes that such net operating loss carryforwards from On-X will be fully realizable prior to expiration. The deferred tax assets recorded on the Company’s Consolidated Balance Sheets exclude amounts that it expects will not be realizable due to these changes in control. A portion of the acquired net operating loss carryforwards is related to state income taxes for which management believes it is more likely than not that these deferred tax assets will not be realized. Therefore, the Company recorded a valuation allowance against these state net operating loss carryforwards. ﻿ Valuation of Acquired Assets or Businesses ﻿ As part of its corporate strategy, the Company is seeking to identify and capitalize upon acquisition opportunities of complementary product lines and companies. The Company evaluates and accounts for acquired patents, licenses, distribution rights, and other tangible or intangible assets as the purchase of an asset or asset group or as a business combination, as appropriate. The determination of whether the purchase of a group of assets should be accounted for as an asset group or as a business combination requires significant judgment based on the weight of available evidence. ﻿ For the purchase of an asset group, the Company allocates the cost of the asset group, including transaction costs, to the individual assets purchased based on their relative estimated fair values. In-process research and development acquired as part of an asset group is expensed upon acquisition. The Company accounts for business combinations using the acquisition method. Under this method, the allocation of the purchase price is based on the fair value of the tangible and identifiable intangible assets acquired and the liabilities assumed as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the tangible net assets and identifiable intangible assets is recorded as goodwill. Transaction costs related to business combinations are expensed as incurred. In-process research and development acquired as part of a business combination is accounted for as an indefinite-lived intangible asset until the related research and development project gains regulatory approval or is discontinued. ﻿ The Company typically engages external advisors to assist it in determining the fair value of acquired asset groups or business combinations, using valuation methodologies such as: the excess earnings, the discounted cash flow, or the relief from royalty methods. The determination of fair value in accordance with the fair value measurement framework requires significant judgments and estimates, including, but not limited to: timing of product life cycles, estimates of future revenues, estimates of profitability for new or acquired products, cost estimates for new or changed manufacturing processes, estimates of the cost or timing of obtaining regulatory approvals, estimates of the success of competitive products, and discount rates. Management, in consultation with its advisor(s), makes these estimates based on its prior experiences and industry knowledge. Management believes that its estimates are reasonable, but actual results could differ significantly from the Company’s estimates. A significant change in management’s estimates used to value acquired asset groups or business combinations could result in future write-downs of tangible or intangible assets acquired by the Company and, therefore, could materially impact the Company’s financial position and profitability. If the value of the liabilities assumed by the Company, including contingent liabilities, is determined to be significantly different from the amounts previously recorded in purchase accounting, the Company may need to record additional expenses or write-downs in future periods, which could materially impact the Company’s financial position and profitability. ﻿ Derivative Instruments ﻿ The Company determines the fair value of its stand-alone and embedded derivative instruments at issuance and records any resulting asset or liability on the Company’s Consolidated Balance Sheets. Changes in the fair value of the derivative instruments are recognized in other (income) expense on the Company’s Consolidated Statements of Operations and Comprehensive Income. ﻿ New Accounting Pronouncements ﻿ In February 2016, the Financial Accounting Standards Board (“FASB”) amended its Accounting Standards Codification and created a new Topic 842, Leases. The final guidance requires lessees to recognize a right-of-use asset and a lease liability for all leases (with the exception of short-term leases) at the commencement date and recognize expenses on their income statements similar to the current Topic 840, Leases. It is effective for fiscal years and interim periods beginning after December 15, 2018, and early adoption is permitted. The Company is evaluating the impact the adoption of this standard will have on its financial position, results of operations, and cash flows. ﻿ In March 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting as part of its simplification initiative, which involves several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company expects that the allowed change in accounting for forfeitures as they occur will not have a material impact on the Company’s results of operations over time, as the Company believes that its estimated forfeiture rate approximates its actual forfeiture rate. However, the Company believes that this could have a favorable or unfavorable impact in any given quarter due to the timing of actual forfeitures. The Company believes that the change in accounting for excess tax benefits and the discontinuance of the APIC pool could have a material impact on its results of operations, which could be favorable or unfavorable, depending on movements in the Company’s stock price. The Company does not believe the adoption of this standard will have a material impact on its financial position and cash flows. ﻿ In May 2014 the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. Since ASU 2014-09 was issued, several additional ASUs have been issued to clarify various elements of the guidance. These standards provide guidance on recognizing revenue, including a five-step model to determine when revenue recognition is appropriate. The standard requires that an entity recognize revenue to depict the transfer of control 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. Adoption of the new standard is effective for reporting periods beginning after December 15, 2017, and early adoption is permitted. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company is performing its initial evaluation of its standard arrangements with customers and its arrangements specific to certain of the Company’s product lines or product offerings. The Company is continuing to evaluate the effect that ASU 2014-09 will have on its financial position, results of operations, cash flows, and related disclosures. ﻿
