Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The interim consolidated financial statements reflect all adjustments which in the opinion of management are necessary for a fair statement of results of operations, comprehensive income, financial condition, cash flows and stockholders' equity for the periods presented. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. The interim consolidated financial statements have been compiled without audit. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s 2012 Annual Report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements as of December 31, 2012, but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”). The Company completed the sale of its OralDNA salivary-diagnostics business ("OralDNA") during the fourth quarter of 2012. In April 2013, the Company completed the sale of its HemoCue diagnostics products business ("HemoCue"). During the third quarter of 2006, the Company completed its wind-down of NID, a test kit manufacturing subsidiary, and classified the operations of NID as discontinued operations. The accompanying consolidated statements of operations and related disclosures have been recast to report the results of OralDNA and HemoCue as discontinued operations for the three and six months ended June 30, 2013 and 2012. See Note 12 for a further discussion of discontinued operations. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Earnings Per Share The Company's unvested restricted common stock and unvested restricted stock units that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in the earnings allocation in computing earnings per share using the two-class method. Basic earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding. Diluted earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding after giving effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the dilutive effect of outstanding stock options and performance share units granted under the Company's Amended and Restated Employee Long-Term Incentive Plan and its Amended and Restated Non-Employee Director Long-Term Incentive Plan. Earnings allocable to participating securities include the portion of dividends declared as well as the portion of undistributed earnings during the period allocable to participating securities. Adoption of New Accounting Standards On January 1, 2013, the Company adopted a new accounting standard issued by the Financial Accounting Standards Board ("FASB") related to the testing of indefinite-lived intangible assets, other than goodwill, for impairment. Similar to the guidance related to the testing of goodwill for impairment, an entity testing an indefinite-lived intangible asset for impairment has the option to perform a qualitative assessment before calculating the fair value of the asset. If, after assessing the totality of events and circumstances an entity determines that it is not more-likely-than-not that the indefinite-lived intangible asset is impaired, the entity would not be required to perform the quantitative impairment test. However, if the qualitative assessment indicates that it is more-likely-than-not that the fair value of the asset is less than its carrying amount, then the quantitative assessment must be performed. An entity is permitted to perform the qualitative assessment on none, some or all of its indefinite-lived intangible assets and may also bypass the qualitative assessment and begin with the quantitative assessment of indefinite-lived intangible assets for impairment. The adoption of this new standard did not have a material impact on the Company’s consolidated financial statements. On January 1, 2013, the Company adopted a new accounting standard issued by the FASB that adds new disclosure requirements for amounts reclassified out of accumulated other comprehensive income ("AOCI"). The total changes in AOCI must be disaggregated between reclassification adjustments and current period other comprehensive income. This new standard also requires an entity to present reclassification adjustments out of AOCI either on the face of the income statement or in the notes to the financial statements based on their source and the income statement line items affected by the reclassification. This standard is effective prospectively for the Company for interim and annual periods beginning on January 1, 2013. The adoption of this new standard did not have a material impact on the Company’s consolidated financial statements. New Accounting Pronouncements In March 2013, the FASB issued a new accounting standard on foreign currency matters that clarifies the guidance of a parent company's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this new standard, a parent company that ceases to have a controlling financial interest in a foreign subsidiary or group of assets within a foreign entity shall release any related cumulative translation adjustment into net income only if a sale or transfer results in complete or substantially complete liquidation of the foreign entity. This standard shall be applied prospectively and will become effective for the Company on January 1, 2014. The Company expects that the adoption of this standard will not have a material effect on its consolidated financial statements. In July 2013, the FASB issued a new accounting standard to permit the use of the Fed Funds Effective Swap Rate to be used as an alternative benchmark interest rate for hedge accounting purposes in interest rate derivatives. The new standard is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The new standard is not expected to have a material effect on the Company's consolidated financial statements. In July 2013, the FASB issued a new accounting standard on the financial statement presentation of unrecognized tax benefits. The new standard provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new standard becomes effective for the Company on January 1, 2014 and it should be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The Company is currently assessing the impacts of this new standard.
