(1) Unless specific in nature, the amount of provision or reversal of reserves related to prior periods for chargebacks is not determinable on a product or customer specific basis; however, based upon historical analysis and analysis of activity in subsequent periods, we have determined that our chargeback estimates remain reasonable.

(2) Includes amounts due to indirect customers for which no underlying accounts receivable exists and is principally comprised of Medicaid rebates and rebates due under other U.S. Government pricing programs, such as TriCare, and the Department of Veterans Affairs.

(3) The amount principally represents the resolution of a customer dispute in the first quarter of 2012 regarding invalid deductions taken in prior years of approximately $1,700 thousand.
