Lines of Business [Abstract]

Segment Reporting

     Our reportable segments are Animal Hospital, Laboratory and Medical Technology. These segments are strategic business units that have different services, products and/or functions. The segments are managed separately because each is a distinct and different business venture with unique challenges, risks and rewards. Our Animal Hospital segment provides veterinary services for companion animals and sells related retail and pharmaceutical products. Our Laboratory segment provides diagnostic laboratory testing services for veterinarians, both associated with our animal hospitals and those independent of us. Our Medical Technology segment sells digital radiography and ultrasound imaging equipment, related computer hardware, software and ancillary services to the veterinary market. We also operate a corporate office that provides general and administrative support services for our other segments.

     The accounting policies of our segments are essentially the same as those described in the summary of significant accounting policies included in our 2010 Annual Report on Form 10-K. We evaluate the performance of our segments based on gross profit and operating income. For purposes of reviewing the operating performance of our segments all intercompany sales and purchases are generally accounted for as if they were transactions with independent third parties at current market prices.

Fair Value Measurement

     In May 2011, the Financial Accounting Standards Board (FASB) amended the accounting guidance for Fair Value Measurement to achieve common fair value measurement and disclosure requirements in U.S. GAAP and IFRS (International Financial Reporting Standards). The amendments explain how to measure fair value, however they do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices outside of financial reporting. The amendments are to be applied prospectively and are effective during interim and annual periods beginning after December 15, 2011. Early application by public entities is not permitted. The adoption of this new guidance is not expected to have a significant impact our consolidated financial statements.

Presentation of Comprehensive Income

     In June 2011, the FASB finalized the accounting guidance for the Presentation of Comprehensive Income. The objective of the new guidance is to improve the comparability, consistency, and transparency of financial reporting, to increase the prominence of the items reported in other comprehensive income and to facilitate convergence of GAAP and IFRS. The guidance eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholder’s equity and requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The statement of other comprehensive income should immediately follow the statement of net income. Regardless of which option is chosen it is required that reclassification adjustments for items that are reclassified from other comprehensive income to net income be presented on the face of the financial statements.

     The new guidance does not change the following: the items that must be reported in other comprehensive income; when an item of other comprehensive income must be reclassified to net income; the option for an entity to present components of other comprehensive income either net of related tax effects or before related tax effects; and does not affect how earnings per share is calculated or presented.

     The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and should be applied retrospectively. Early adoption is permitted. The adoption of the new disclosure requirements will have no effect on our consolidated financial statements other than the changes to presentation outlined.
