Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 to its audited consolidated financial statements for the year ended December 31, 2012, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC on March 4, 2013. Except as discussed below, these accounting policies have not significantly changed during the nine months ended September 30, 2013. Impairment Analysis of Goodwill The Company performs its test for goodwill impairment annually during the fourth quarter and in interim periods if certain events occur indicating that the carrying value of goodwill may be impaired. During the quarter ended September 30, 2013, the Company concluded that the announcement of the Scient’x restructuring plan (Note 12) was an indicator of a potential impairment in goodwill. As a result, the Company performed an interim impairment test on its single operating unit. The goodwill impairment test is a two-step process. The first step compares the Company’s fair value to its net book value. If the fair value is less than the net book value, the second step of the test compares the implied fair value of the Company’s goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, the Company would recognize an impairment loss equal to that excess amount. The Company estimated the fair value in step one based on the income approach which included discounted cash flows as well as a market approach that utilized the Company’s earnings and revenue multiples and recent sales transactions. The Company’s discounted cash flows required management judgment with respect to forecasted sales, launch of new products, gross margin, selling, general and administrative expenses, capital expenditures and the selection and use of an appropriate discount rate. The Company utilized its weighted average cost of capital as the discount rate for the projected future cash flows and its median revenue and earnings multiples under the market approach. The Company’s assessment resulted in a fair value that was greater than the Company’s carrying value at September 30, 2013. In accordance with the authoritative literature, the second step of the impairment test was not required to be performed and no impairment of goodwill was recorded as of September 30, 2013. Significant management judgment is required in the forecast of future operating results that are used in the Company’s impairment analysis. The estimates the Company used are consistent with the plans and estimates that it uses to manage its business going forward. Significant assumptions utilized in the Company’s income approach model included the revenue growth rate for existing products, the introduction of newly launched and anticipated products, the projected regional mix of higher margin U.S. based revenues and lower margin non-U.S. based revenues, and the projected improvement in its gross margin based on product, channel and regional mix combined with long-term manufacturing efficiency gains. The estimated fair value of the Company as calculated in the third quarter interim test could be materially affected, both negatively and positively, with significant changes to the discount rate and other key forward looking assumptions. The Company will re-assess goodwill impairment when it performs its annual test for impairment in December 31, 2013. Impairment of Long-Lived Assets The Company assesses potential impairment to its long-lived assets when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized when the carrying amount of the long-lived assets is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Any required impairment loss is measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value and is recorded as a reduction in the carrying value of the related asset and a charge to operating results. During the quarter ended September 30, 2013, the Company decided that it would not continue to market an adult stem cell product sold under the Company's private label name, Puregen. The company also decided that it would no longer actively market one of its minimally invasive surgery products. The Company expensed $1.1 million as impairment charges in cost of goods sold in the three and nine months ended September 30, 2013 for the write-off of intangible assets related to these products. Due to the Scient'x restructuring plan, the Company assessed potential impairment on certain intangible assets related to the Scient'x acquisition. Based on this assessment the projected undiscounted cash flows exceeded the carrying amount of the intangible assets and no impairment loss was recognized in the three and nine months ended September 30, 2013. Recent Accounting Pronouncements In March 2013, the Financial Accounting Standards Board (“FASB”) issued guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The amendments will be effective for the Company beginning January 1, 2014. We do not anticipate any impact on our financial statements upon adoption. In February 2013, the FASB issued guidance that requires a company to disaggregate the total change of each component of other comprehensive income either on the face of the income statement or as a separate disclosure in the notes thereto. The new guidance became effective for the Company’s interim period ended March 31, 2013. The Company adopted this guidance and the adoption did not have any impact on its financial position, results of operations or cash flows. In July 2013, the FASB issued guidance that requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, unless an exception applies. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2013. The Company will reflect the impact of these amendments beginning with the Company's Quarterly Report on Form 10-Q for the period ending March 31, 2014. The Company does not anticipate a material impact to the Company's financial position, results of operations or cash flows as a result of this change.
