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 3.
