[1] Prior year data has been reclassified to conform to the current year's presentation. Effective January 1, 2014, the Company merged its Allied Health Group, LLC subsidiary with its Medical Doctor Associates, LLC subsidiary. The decision to merge these companies was based on a number of factors including the consolidation of back office processes and other operational efficiencies. Along with this merger, the Company evaluated the Allied Health Group trade name and determined that it would be more valuable to use it for the Company’s nurse and allied staffing business, and as a result, transferred the trade name effective January 1, 2014. The allied health staffing business of MDA has primarily consisted of higher-level allied professionals, such as physician assistants and nurse practitioners, whose job functions are becoming increasingly more similar to those of physicians than to other allied health professionals. The 2014 change in legal structure and processes, along with the current market dynamics has changed the Company’s approach/conclusion to aggregate this business with its nurse and allied staffing business segment for 2014. The Company has revised its segments for 2014 reporting to include this business with its physician staffing business segment.

[2] In 2014, the Company refined its methodology for allocating certain corporate overhead expenses to its nurse and allied staffing segment to more accurately reflect this segment’s profitability. Prior year information has been reclassified to conform to current year presentation.
