Our Corporate & Other segment includes the results of APS Healthcare since its acquisition on March 2, 2012, start-up expenses related to the development of our ACOs, and the operations of our parent holding company, including debt service. The loss for the year ended December 31, 2012 decreased year-over-year due primarily to restructuring and other charges incurred in 2011 as well as reductions in 2012 operating expenses. These reductions were partially offset by our $21.7 million investment in the development of ACOs, $3.7 million of 2012 transaction costs related to our acquisition of APS Healthcare, and higher debt service costs. In the year ended December 31, 2011, we incurred $8.6 million of stock-based compensation expense for the accelerated vesting of equity awards in connection with the Part D sale in 2011, and $40.9 million in charges incurred in connection with cost reduction initiatives in our Medicare Advantage, Traditional and Corporate segments, the realignment of our distribution channels and other special items.
