Additions to the reserve charged to expense include $69 and $1,846 of bad debt charges recognized in the settlement of receivables owed by licensees acquired during the three and nine months ended August 27, 2011, respectively (see Note 10).  Also, $1,227 and $3,847 of the write-offs and other deductions during the three and nine months ended August 27, 2011, respectively,  related to the acquired licensees.

We believe that the carrying value of our net accounts receivable approximates fair value. The inputs into these fair value estimates reflect our market assumptions and are not observable.  Consequently, the inputs are considered to be Level 3 as specified in the fair value hierarchy in ASC Topic 820, Fair Value Measurements and Disclosures.  See Note 14.
