Segment Reporting [Abstract]

Lines of Business

Lines of Business

Our reportable segments are Animal Hospital and Laboratory. 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 other operating segments, included in “All Other” in the following tables, are our Medical Technology business, which sells digital radiography and ultrasound imaging equipment, related computer hardware, software and ancillary services to the veterinary market and our Vetstreet business. Vetstreet provides online communications, professional education, marketing solutions to the veterinary community and an ecommerce platform for independent animal hospitals. These operating segments do not meet the quantitative requirements for reportable segments. Our operating 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. We also operate a corporate office that provides general and administrative support services for our segments.

The accounting policies of our segments are essentially the same as those described in the summary of significant accounting policies included in our 2012 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.

The following is a summary of certain financial data for each of our segments (in thousands):
