[1] | Cash and cash equivalents at December 31, 2014 include $2.9 million from the Physician Segment (see "Note 4. Discontinued Operations").
[2] | The December 31, 2014 balances have been adjusted to reflect unamortized deferred loan costs attributable to term loans as a reduction of the related debt balances whereas they were previously included in other current assets and other non-current assets. This change in presentation was the result of early adopting ASU 2015-03. The December 31, 2014 balances for the current portion of long-term debt and long-term debt are now reflected net of $0.8 million and $2.5 million of unamortized deferred loan costs, respectively.
