A reconciliation of the changes in deferred revenue from the sale of warranty contracts and other deferred items for the years ended December 31, 2005 and 2006 is as follows:
The Company earns and accrues franchise revenues based on sales by franchisees which are accrued as earned. Initial franchise fees are recorded as revenue when all material services or conditions relating to the sale of the franchise have been substantially performed or satisfied by the Company and when the related store begins operations. Accruals are established for amounts due under these relationships when they are determined to be uncollectible.
The Wholesale and Retail Divisions may offer certain promotions during the year. Free frames given to customers as part of a promotional offer are recorded in cost of sales at the time they are delivered to the customer. Discounts and coupons tendered by customers are recorded as a reduction of revenue at the date of sale.
