[1] 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.

[2] In December 2010, we reached a settlement related to the routine post award contract review of our contract with the Department of Veterans Affairs for the periods 2004 to 2007 with the Office of Inspector General of the Department of Veterans Affairs. We had previously accrued approximately $10,500 thousand ($6,400 thousand net of related partnership consideration) in accrued government liabilities and payables due to distribution agreement partners on our consolidated balance sheet related to this matter. We reduced this accrual to $7,300 thousand ($3,800 thousand net of related partnership consideration), based on the settlement. Accordingly, we recognized approximately $2,600 thousand of income in the fourth quarter of 2010 as a change in estimate. The 2009 change in accrued liabilities recorded for prior period sales is principally comprised of a $1,400 thousand credit from the Medicaid drug rebate program related to a positive settlement based upon the finalization of a negotiation in the third quarter of 2009 pertaining to prior years. With the exception of the foregoing factor, there were no other factors that were deemed to be material individually or in the aggregate.

[3] 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.

[4] During the first quarter of 2010, the Company settled a dispute with a major customer and as a result recorded an additional reserve of $1,300 thousand.

[5] During the third quarter of 2010, the Company settled a customer dispute related to the January 2009 metoprolol price increase. As a result, the Company recorded an additional reserve of $1,100 thousand.
