The net increase in accrued salaries and bonuses of $15.4 million, from $132.2 million at December 31, 2010 to $147.6 million at December 31, 2011, is primarily due to performance-based incentive compensation accrued during the year ended December 31, 2011, partially offset by the payment of performance-based incentive compensation during the first quarter of 2011. A majority of the Company's payments for performance-based incentive compensation is paid annually in the first quarter. The accrual for uncertain tax positions, which represents the current portion of reserves for uncertain tax positions including interest and penalties, decreased by $7.7 million, from $10.9 million at December 31, 2010 to $3.2 million at December 31, 2011 primarily due to reclassification of certain temporary differences to deferred taxes payable. See Note 11 for more information regarding the Company's uncertain tax positions.
