and record revenues as variable consideration based on the amounts the Company expects to ultimately be entitled. In order to determine estimated returns, the Company utilizes historical return rates, sales patterns, types of products and expectations and recognizes a corresponding reduction to Revenues and Cost of goods sold. Management also considers patterns of sales and returns in the months preceding the fiscal year, as well as actual returns received subsequent to the fiscal year, available customer and market specific data and other return rate information that management believes is relevant. In addition, a refund liability is recorded within Other accrued expenses for the consideration to which the Company believes it will not ultimately be entitled and a return asset is recorded within Prepaid expenses and other current assets for the expected inventory to be returned. Actual returns could differ from the Company's estimate.</span></div>
