The net decrease in accrued salaries and bonuses of $16.0 million, from $147.6 million at December 31, 2011 to $131.6 million at September 30, 2012, is primarily due to the payment of performance-based incentive compensation, principally to the Company’s physicians, partially offset by performance-based incentive compensation accrued during the nine months ended September 30, 2012. A majority of the Company’s payments for performance-based incentive compensation is paid annually in the first quarter.
