Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements Disclosure [Text Block]	2 . Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers,” a new accounting standard that provides for a comprehensive model to use in the accounting for revenue arising from contracts with customers that will replace most existing revenue recognition guidance within generally accepted accounting principles in th e United States. Under this standard, revenue will be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or servi ces. At its July 2015 meeting, the FASB agreed to defer the mandatory effective date of ASU 2014-09 one year. Under the one year deferral, the standard will take effect in 2018 for calendar year-end public entities. The Company is assessing the new standar d and has not yet determined the impact to the consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying Measurement of Inventory . The update requires measurement of most inventory “at the lower of cost and net realizable value”, and applies to all entities that recognize inventory within the scope of ASC 330, except for inventory measured under the last-in, first-out (LIFO) method or the retail inventory method (RIM). ASU 2015-11 requires prospective application and repres ents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is evaluating the impact of ASU 2015- 11 on its consolidated financial statements and the possibility of early adoption by the Company. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments . The update eliminates the requirement to retr ospectively adjust financial statements for measurement-period adjustments that occur in periods after a business combination. Under the update, measurement-period adjustments are to be calculated as if they were known at the acquisition date, but are reco gnized in the reporting period in which they are determined. Additional disclosures are required about the impact on current-period earnings. ASU 2015-16 requires prospective application to adjustments of provisional amounts that occur after the effective date. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is evaluating the impact of ASU 2015-16 on its consolidated financial statements and the possibility of early adoption by the Company. In February 2016, the FASB issued ASU 2016-02, Leases , which is intended to improve financial reporting about leasing transactions. The update requires a lessee to record on the balance shee t the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The update is effective for fiscal years beginning after December 15, 2018. The Company is evaluating the impact of ASU 2016-02 on its consolidated f inancial statements. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies the accounting for share-based payment transactions, including the in come tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The update is effective for fiscal years be ginning after December 15, 2016 and early adoption is permitted. The Company is ev aluating the impact of ASU 2016-09 on its consolidated financial statements. Recently Adopted Accounting Pronouncements In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs . Under this guidance, debt issuance costs related to a recognized debt liability should be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The provisions of this guid ance are to be applied retrospectively and are effective for interim and annual periods beginning after December 15, 2015. The Company adopted this guidance during the three months ended March 31, 2016 . The consolidated balance sheet as of December 31, 2015 , included in these consolidated financial statements, reflects a restatement to reclassify unamortized deferred financing costs of approximately $0.2 million from other long-term assets to long-term debt. For deferred financing costs pa id to secure long-term debt, the Company made a policy election to present such costs as a direct deduction from the debt liability on the consolidated balance sheet. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes . The update requires all deferred income taxes to be presented on the balance sheet as noncurrent. The new guidance is intended to simplify financial reporting by eliminating the requirement to classify deferred taxes between current and noncurrent. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted at the beginning of an interim or annual period. During the three months ended March 31, 2016 , t he Company early adopted the new guidance on a prospective basis and has presented all deferred tax assets and deferred tax liabilities as noncurrent in the consolidated balance sheet at March 31, 2016 .

Capital Stock Disclosure [Abstract]
Capital Stock Disclosure [Text Block]	13 . Capital Stock Common Stock On February 5, 2008, the Company’s Board of Directors adopted a Shareholder Rights Plan and declared a dividend distribution of one preferred stock purchase right for each outstanding share of the Company’s common stock to shareholders of record as of the close of business on February 6, 2 008. Initially, these rights will not be exercisable and will trade with the shares of the Company’s common stock. Under the Shareholder Rights Plan, the rights generally will become exercisable if a person becomes an “acquiring person” by acquiring 20% or more of the common stock of the Company or if a person commences a tender offer that could result in that person owning 20% or more of the common stock of the Company. If a person becomes an acquiring person, each holder of a right (other than the acquiri ng person) would be entitled to purchase, at the then-current exercise price, such number of shares of preferred stock which are equivalent to shares of the Company’s common stock having a value of twice the exercise price of the right. If the Company is a cquired in a merger or other business combination transaction after any such event, each holder of a right would then be entitled to purchase, at the then-current exercise price, shares of the acquiring company’s common stock having a value of twice the ex ercise price of the right. Preferred Stock The Company’s Board of Directors has the authority to issue up to 5.0 million shares of preferred stock and to determine the price privileges and other terms of the shares. The Board of Directors may exercise th is authority without any further approval of stockholders. As of March 31, 2016 , the Company had no preferred stock issued or outstanding . Employee Stock Purchase Plan (as amended, the “ESPP”) In 2000, the Company approved the ESPP . Under thi s ESPP , participating employees can authorize the Company to withhold a portion of their base pay during consecutive six-month payment periods for the purchase of shares of the Company’s common stock. At the conclusion of the period, participating employee s can purchase shares of the Company’s common stock at 85% of the lower of the fair market value of the Company’s common stock at the beginning or end of the period. Shares are iss ued under the ESPP for the six-month periods ending June 30 and December 31. Under this plan, 750,000 shares of common stock are authorized for issuance of which 644,011 shares were issue d as of March 31, 2016 . During the three months ended March 31, 2016 and 2015 , no shares of the Compa ny’s common stock were issued under the ESPP. Stock Option Plans Third Amended and Restated 2000 Stock Option and Incentive Plan (as amended, the “Third A&R Plan”) The Second Amendment to the Third A& R Plan (the “Amendment”) was adopted by the Board of Directors on April 3, 2015. Such Amendment was approved by the stockholders at the Company’s 2015 Annual Meeting of Stockholders . Pursuant to the Amendment, the aggregate number of shares authorized for issuance under the Third A&R Plan was increased by 2,500,000 shares to 17,508,929. Restricted Stock Units with a Market Condition (the “Market Condition RSU’s”) On August 3, 2015, the Compensation Committee of the Board of Directors of the Company appro ved and granted deferred stock awards of Market Condition RSU’s to members of the Company’s management team under the Third A&R Plan. The vesting of these Market Condition RSU’s is cliff-based and linked to the achievement of a relative total shareholder return of the Company’s common stock from August 3, 2015 to the earlier of ( i ) August 3, 2018 or (ii) upon a change of control (measured relative to the Russell 3000 index and based on the 20-day trading average price before each such date). As of March 31, 2016 , t he target number of these restricted stock units that may be earned is 196,785 shares; the maximum amount is 150% of the target number. Stock-Based Payment Awards The Company accounts for stock-based payment awards in accordance with the provisions of FASB ASC 718, which requires it to recognize compensation expense for all stock-based payment awards made to employees and directors including stock options, restricted stock units, Market Condition RSU’s and employee stock purchases rel ated to the ESPP. Stock option and restricted stock unit activity under the Company’s Third A&R Plan for the three months ended March 31, 2016 was as follows: Stock Options Restricted Stock Units Market Condition RSU's Weighted Stock Average Restricted Market Options Exercise Stock Units Grant Date Condition RSU's Grant Date Outstanding Price Outstanding Fair Value Outstanding Fair Value Balance at December 31, 2015 5,022,186 $ 3.85 313,559 $ 5.29 185,538 $ 4.81 Granted 16,000 2.87 110,400 3.23 - - Vested (RSUs) - - (122,920) 4.30 - - Cancelled / forfeited (63,746) 4.24 - - - - Balance at March 31, 2016 4,974,440 $ 3.84 301,039 $ 4.94 185,538 $ 4.81 The weighted average fair value of the options granted under the Third A&R Plan during the three months ended March 31, 2016 and 2015 was $ 1.11 and $ 2.30 , respectively. The following assumptions were used to estimate the fair value , using the Black -Scholes option pricing model, of stock options granted during the three months ended March 31, 2016 and 2015 : Three Months Ended March 31, 2016 2015 Volatility 40.26 % 42.34 % Risk-free interest rate 1.48 % 1.74 % Expected holding period (in years) 5.36 years 5.70 years Dividend yield - % - % The Company used historical volatility to calculate the expected volatility for each grant as of the grant date . Historical volatility was determined by calculating the mean reversion of the daily adjusted closing stock price. The risk-free interest rate assumption is based upon observed U.S. Treasury bill interest rates (risk-free) appropriate for the term of the Company’s stock options and Market Condition RSU’s. The expected holding period of stock options represents the period of time options are expec ted to be outstanding and is based on historical experience. The vesting period ranges from one to four years and the contractual life is ten years. The correlation coefficient, used to value the Market Condition RSU’s, represents the way in which entities move in relation to the Russell 3000 index as a whole. Stock- based c ompensation expense related to stock options, restricted stock units , Market Condition RSU’s and the ESPP for the three months ended March 31, 2016 and 2015 was alloca ted as follows: Three Months Ended March 31, 2016 2015 (in thousands) Cost of revenues $ 11 $ 21 Sales and marketing 101 87 General and administrative 622 449 Research and development 20 23 Total stock-based compensation $ 754 $ 580 The Company did not capitalize any stock-based compensation. Earnings per share Basic earnings per share is based upon net income divided by the number of weighted average common shares outstanding during the period. The calculation of diluted earnings per share assumes conversion of stock options, restricted stock units and Market Condition RSU’s into common stock using the treasury method. The weighted av erage number of shares used to compute basic and diluted earnings per share consists of the following: Three Months Ended March 31, 2016 2015 Basic 34,013,352 32,908,101 Effect of assumed conversion of employee and director stock options, restricted stock units and Market Condition RSU's - - Diluted 34,013,352 32,908,101 Excluded from the shares used in calculating the diluted earnings per common share in the above table are options, restricted stock units and Market Condition RSU’s of approximately 5,461,017 and 5,331,821 shares of common stock for the three months ended March 31, 2016 and 2015 , respectively, as the impact of these shares would be anti-dilutive.

Long Term Debt Disclosure [Abstract]
Long Term Debt Disclosure [Text Block]	14 . Long Term Debt On August 7, 2009, the Company entered into an Amended and Restated Revolving Credit Loan Agreement related to a $20.0 million revolving credit facility with Bank of America, as agent, and Bank of America and Brown Brothers Harriman & Co as lenders (as amended, the “2009 Credit Agreement”) . On September 30, 2011, the Company entered into the First Amendment to the Amended and Restated Revolving Credit Loan Agreement (the “First Amendment”) with Bank of America as agent, and Bank of Ame rica and Brown Brothers Harriman & Co as lenders. The First Amendment extended the maturity date of the credit facility to August 7, 2013 and reduced the interest rate to the London Interbank Offered Rate plus 3.0%. On October 4, 2012, the Company entered into the Second Amendment to the Amended and Restated Revolving Credit Loan Agreement (the “Second Amendment”) with Bank of America as agent, and Bank of America and Brown Brothers Harriman & Co as lende rs. The Second Amendment extended the maturity date o f the credit facility to August 7, 2014 . On March 29, 2013, the Company entered into a Second Amended and Restated Revolving Credit Agreement ( as amended, the “Credit Agreement”) with Bank of America, as agent, and Bank of America and Brown Brothers Harri man & Co as lenders , that amended and restated the 2009 Credit Agreement . The Credit Agreement converted the Company’s existing outstanding revolving advances into a term loan in the principal amount of $15.0 million (the “Term Loan”), provides a revolving credit facility in the maximum principal amount of $25.0 million (“Revolving Line”) and provides a delayed draw term loan of up to $15.0 million (the “DDTL”) to fund capital contributions to the Company’s former subsidiary, Biostage . The maximum amount a vailable under the Credit Agreement is $50.0 million as borrowings against the DDTL in excess of $10.0 million results in a dollar for dollar reduction in the Revolving Line capacity. The Revolving Line, Term Loan and DDTL each have a maturity date of Marc h 29, 2018 (the maturity date of the Revolving Line was extended from March 29, 2016 in connection with the Third Amendment discussed below). On October 31, 2013, the Company amended the Credit Agreement to reduce the DDTL from up to $15.0 million to up to $10.0 million and allow for an additional $5.0 million to be available for drawing as advances under the Revolving Line. On April 24, 2015, the Company entered into the Third Amendment to the Second Amended and Restated Credit Agreement (the “Thi rd Amendment”). The Third Amendment extended the maturity date of the Revolving Line to March 29, 2018 and reduced the interest rates on the Revolving Line, Term Loan and DDTL. B orrowings under the Term Loan and the DDTL accrued interest at a rate based o n either the effective London Interbank Offered Rate (LIBOR) for certain interest periods selected by the Company, or a daily floating rate based on the British Bankers’ Association (BBA) LIBOR as published by Reuters (or other commercially available sourc e providing quotations of BBA LIBOR), plus in either case, a margin of 2.75 %. Additionally, t he Revolving Line accrued interest at a rate based on either the effective LIBOR for certain interest periods selected by the Company, or a daily floating rate bas ed on the BBA LIBOR, plus in either case, a margin of 2. 25 %. The Company was required to fix the rate of interest on at least 50% of the Term Loan and the DDTL through the purchase of interest rate swaps. The Term Loan and DDTL each have interest payments due at the end of the applicable LIBOR period, or monthly with respect to BBA LIBOR borrowings, and principal payments due quarterly. The Revolving Line has interest payments due at the end of the applicable LIBOR period, or monthly with respect to BBA LI BOR borrowings. On June 30, 2015, the Company entered into the Fourth Amendment to the Second Amended and Restated Credit Agreement, which amended the Company’s quarterly minimum fixed charge coverage financial covenant. On November 5, 2015, the Company entered into the Fifth Amendment to the Second Amended and Restated Credit Agreement, which eliminated the Company’s 2015 fourth quarter minimum fixed charge coverage financial covenant requirement. As part of the agreement, the maximum principal amount o n the Revolving Line was reduced to $10.0 million until June 30, 2016, at which time, the maximum principal amount will be restored to $25.0 million, as long as the Company remains in compliance with all covenants. On March 9, 2016 , the Company entered in to the Sixth Amendment to the Second Amended and Restated Credit Agreement, which amended the principal payment amortization of the Term Loan and DDTL to five years, as well as amended the Company’s quarterly minimum fixed charge coverage financial covenan t. The loans evidenced by the Credit Agreement, or the Loans, are guaranteed by all of the Company’s direct and indirect domestic subsidiaries, and secured by substantially all of the assets of the Company and the guarantors. The Loans are subject to rest rictive covenants under the Credit Agreement, and financial covenants that require the Company and its subsidiaries to maintain certain financial ratios on a consolidated basis, including a maximum leverage, minimum fixed charge coverage and minimum workin g capital. Prepayment of the Loans is allowed by the Credit Agreement at any time during the terms of the Loans. The Loans also contain limitations on the Company’s ability to incur additional indebtedness and requires lender approval for acquisitions fund ed with cash, promissory notes and/or other consideration in excess of $6.0 million and for acquisitions funded solely with equity in excess of $10.0 million. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest - Imputation o f Interest - Simplifying the Presentation of Debt Issuance Costs . Under this guidance, debt issuance costs related to a recognized debt liability should be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability . The provisions of this guidance are to be applied retrospectively and are effective for interim and annual periods beginning after December 15, 2015. The Company adopted this guidance during the three months ended March 31, 2016 . The consolidated balance sheet as of December 31, 2015 , included in these consolidated financial statements, reflects a restatement to reclassify unamortized deferred financing costs of approximately $0.2 million from other long-term assets to long-term debt. Fo r deferred financing costs paid to secure long-term debt, the Company made a policy election to present such costs as a direct deduction from the debt liability on the consolidated balance sheet. As of March 31, 2016 and December 31, 2015 , the C ompany had net borrowings of $ 17.1 million and $ 18.7 million, respectively, outstanding under its Credit Agreement. As of March 31, 2016 , the Company was in compliance with all financial covenants contained in the Cred it A greement, was subject to covenant and w orking capital borrowing restriction s and had available borrowing capacity under its Credit Agreement of $ 4.4 million . As of March 31, 2016 , the weighted effective interest rates , net of the impact of the Company’s interest rate swaps, on its Term Loan, DDTL and Revolving Line borrowings were 3.96% , 3.56% and 2.68% , respectively. As of March 31, 2016 and December 31, 2015 , the Company’s borrowings were comprised of: March 31, December 31, 2016 2015 (in thousands) Long-term debt: Term loan $ 6,412 $ 6,750 DDTL 5,225 5,500 Revolving line 5,650 6,650 Total unamortized deferred financing costs (139) (167) Total debt 17,148 18,733 Less: current installments (2,450) (2,450) Current unamortized deferred financing costs 74 86 Long-term debt $ 14,772 $ 16,369

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	15 . Derivatives The Company uses interest -rate -related derivative instruments to manage its exposure related to changes in interest rates on its variable -rate debt instruments. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. The Company does not speculate using derivative instruments. By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the f ailure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative co ntract is negative, the Company owes the counterparty and, therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transaction s with carefully selected major financial institutions based upon their credit profile. Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The market risk associated with interest -rat e contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. The Company assesses interest rate risk by continually identifying and monitoring changes in interest rate exposures th at may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company maintains risk management control systems to monitor interest rate risk attributable to both the Company’s outstanding or forecasted debt obligations as well as the Company’s offsetting hedge positions. The risk management control systems involve the use of analytical techniques, including cash flow sensitivity analysis, to estimate the expected impact of changes in interest rates on the Company’s future cash flows. The Company uses variable -rate London Interbank Offered Rate (LIBOR) debt to finance its operations. The debt obligations expose the Company to variability in interest payments due to changes in interest rates. Management believes that it is p rudent to limit the variability of a portion of its interest payments. To meet this objective, management enters into LIBOR based interest rate swap agreements to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LI BOR. These swaps change the variable -rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps, the Company receives LIBOR based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt for the notional amount of its debt hedged. In accordance with its Credit Agreement, the Company was required to fix the rate of interest on at least 50% of its Term Loan and the DDTL through the purchase of interest rate swaps. On June 5, 2013, the Company entered into an interest rate swap contract with an original notional amount of $15.0 million and a maturity date of March 29, 2018 in order to hedge the risk of changes in the effective benchmark inter est rate (LIBOR) associated with the Company’s Term Loan. On November 29, 2013, the Company entered into a second interest rate swap contract with an original notional amount of $5.0 million and a maturity date of March 29, 2018 in order to hedge the risk of changes in the effective benchmark interest rate (LIBOR) associated with the DDTL. The notional amount of the Company’s derivative instruments as of March 31, 2016 was $8 .5 million . The Term Loan swap contract effectively converted specific variable-rate debt into fixed-rate debt and fixed the LIBOR rate associated with the Term Loan at 0.96% plus a ba nk margin of 3.0% . The DDTL swap contract effectively converted specific variable-rate debt into fixed-rate debt and fixed the LIBOR rate associated with the Term Loan at 0.93% plus a bank margin of 3.0% .The interest rate swap s were designated as cash flow hedge s in accordance with ASC 815, Derivatives and Hedging . The following table pr esents the notional amount and fair value of the Company ’ s derivative instrument s as of March 31, 2016 and December 31, 2015 . March 31, 2016 March 31, 2016 Notional Amount Fair Value (a) Derivatives designated as hedging instruments under ASC 815 Balance sheet classification (in thousands) Interest rate swaps Other liabilities-non current $ 8,500 $ (33) December 31, 2015 December 31, 2015 Notional Amount Fair Value (a) Derivatives designated as hedging instruments under ASC 815 Balance sheet classification (in thousands) Interest rate swaps Other liabilities-non current $ 9,500 $ (10) (a) See Note 16 for the fair value measurements related to these financial instruments. All of the Company’s derivative instruments are designated as hedging instruments. The Company has structured its interest rate swap agreements to be 100% effective and as a result, there was no impact to earnings resulting from hedge ineffectiveness. Changes in the fair value of interest rate swaps designated as hedging instruments that effectively offset the variability of cash flows associate d with variable -rate, long -term debt obligations are reported in accumulated other comprehensive income (“AOCI”). These amounts subsequently are reclassified into interest expense as a yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings. The Company’s interest rate swap agreement was deemed to be fully effective in accordance with ASC 815, and, as such, unrealized gains and losses related to these derivatives were recorded as AOCI. The followi ng table summarizes the effect of derivatives designated as cash flow hedging instruments and their classification within comprehensive loss for the three months ended March 31, 2016 and 2015 : Derivatives in Hedging Relationships Amount of gain or (loss) recognized in OCI on derivative (effective portion) Three Months Ended March 31, 2016 2015 (in thousands) Interest rate swaps $ (36) $ (59) The following table summarizes the reclassifications out of accumulated other comprehensive loss for the three months ended March 31, 2016 and 2015 : Details about AOCI Components Amount reclassified from AOCI into income (effective portion) Location of amount Three Months Ended March 31, reclassified from AOCI 2016 2015 into income (effective portion) (in thousands) Interest rate swaps $ 13 $ 26 Interest expense As of March 31, 2016 , $ 28,000 of deferred losses on derivative instruments accumulated in AOCI are expected to be reclassified to earnings during the next twelve months. Transactions and events expected to occur over the next twelve months that will necessitate reclassifying these derivatives’ losses to earnings include the repricing of variable -rate debt. There were no cash flow hedges discontinued during 2016 or 2015 .

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	16 . Fair Value Measurements Fair value measurement is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy is established, which prioritizes the inputs used in measuring fair value into three broad levels as follows: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly. Level 3—Unobservable inputs based on the Company’s own assumptions. The following table s present the fair value hierarchy for those liabili ties measured at fair value on a recurring basis: Fair Value as of March 31, 2016 (In thousands) Level 1 Level 2 Level 3 Total Liabilities: Interest rate swap agreements $ - $ 33 $ - $ 33 Fair Value as of December 31, 2015 (In thousands) Level 1 Level 2 Level 3 Total Liabilities: Interest rate swap agreements $ - $ 10 $ - $ 10 The Company uses the market approach technique to value its financial liabilities. The Company’s financial liabilities carried at fair value include derivative instruments used to hedge the Company’s interest rate risks. The fair value of the Company’s interest rate swap agreement s was based on LIBOR yield curves at the reporting date.

Income Tax [Abstract]
Income Taxes Disclosure [Text Block]	17 . Income Tax Income tax was an approximately $ 0.2 million expense and $ 0.4 million benefit for the three months ended March 31, 2016 and 2015 , respectively. The effective income tax rate was 15.0% for the three months ended March 31, 2016 , compared with a benefit of 20.6% for the same period in 2015 . The tax rate for the three months ended March 31, 2016 was based on actual results for the three-month period rather than an ef fective tax rate estimated for the entire year. The Company determined that using a year-to-date approach resulted in a better estimate of income tax expense based on its 2016 forecast of pre-tax income, the mix of income across several jurisdicti ons with different statutory tax rates, and the impact of the full valuation allowance against U.S. deferred tax assets. The difference between the Company’s effective tax rate quarter over quarter was primarily attributa ble to higher pre-tax income in 2016 versus 2015, as well as the mix of earnings between its domestic and foreign businesses. In November 2015, the FASB issued ASU 2015- 17, Balance Sheet Classification of Deferred Taxes . The update requires all deferred income taxes to be presented on the balance sheet as noncurrent. The new guidance is intended to simplify financial reporting by eliminating the requirement to classify de ferred taxes between current and noncurrent. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted at the beginning of an interim or annual period. During the three months ended March 31, 2016 , the Company early adopted the new guidance on a prospective basis and has presented all deferred tax assets and deferred tax liabilities as noncurrent in the consolidated balance sheet at March 31, 2016 . Prior periods presented in the consolidated financial statements were not retrospectively adjusted.

Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements Disclosure [Text Block]	2 . Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers,” a new accounting standard that provides for a comprehensive model to use in the accounting for revenue arising from contracts with customers that will replace most existing revenue recognition guidance within generally accepted accounting principles in th e United States. Under this standard, revenue will be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or servi ces. At its July 2015 meeting, the FASB agreed to defer the mandatory effective date of ASU 2014-09 one year. Under the one year deferral, the standard will take effect in 2018 for calendar year-end public entities. The Company is assessing the new standar d and has not yet determined the impact to the consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying Measurement of Inventory . The update requires measurement of most inventory “at the lower of cost and net realizable value”, and applies to all entities that recognize inventory within the scope of ASC 330, except for inventory measured under the last-in, first-out (LIFO) method or the retail inventory method (RIM). ASU 2015-11 requires prospective application and repres ents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is evaluating the impact of ASU 2015- 11 on its consolidated financial statements and the possibility of early adoption by the Company. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments . The update eliminates the requirement to retr ospectively adjust financial statements for measurement-period adjustments that occur in periods after a business combination. Under the update, measurement-period adjustments are to be calculated as if they were known at the acquisition date, but are reco gnized in the reporting period in which they are determined. Additional disclosures are required about the impact on current-period earnings. ASU 2015-16 requires prospective application to adjustments of provisional amounts that occur after the effective date. The update is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is evaluating the impact of ASU 2015-16 on its consolidated financial statements and the possibility of early adoption by the Company. In February 2016, the FASB issued ASU 2016-02, Leases , which is intended to improve financial reporting about leasing transactions. The update requires a lessee to record on the balance shee t the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The update is effective for fiscal years beginning after December 15, 2018. The Company is evaluating the impact of ASU 2016-02 on its consolidated f inancial statements. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies the accounting for share-based payment transactions, including the in come tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The update is effective for fiscal years be ginning after December 15, 2016 and early adoption is permitted. The Company is ev aluating the impact of ASU 2016-09 on its consolidated financial statements.
