Restaurant sales include the sale of food and beverage products to our customers. We recognize this revenue when the products are sold. All sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from revenue in the consolidated statements of income and comprehensive income.

Other sales include the amortization of gift card breakage and fees associated with third party gift card sales. We record deferred revenue for gift cards that have been sold but not yet redeemed. When the gift cards are redeemed, we recognize restaurant sales and reduce deferred revenue. For some of the gift cards that are sold, the likelihood of redemption is remote. When the likelihood of a gift card's redemption is determined to be remote, we record a breakage adjustment and reduce deferred revenue by the amount never expected to be redeemed. We use historic gift card redemption patterns to determine when the likelihood of a gift card's redemption becomes remote and have determined that approximately 4% of the value of the gift cards sold by our company and our third party retailers will never be redeemed. This breakage adjustment is recorded consistent with the historic redemption pattern of the associated gift card. In addition, we incur fees on all gift cards that are sold through third party retailers. These fees are also deferred and recorded consistent with the historic redemption pattern of the associated gift cards. For the 13 weeks ended March 27, 2018, we recognized gift card fees, net of gift card breakage income, of approximately $1.8 million. Total deferred revenue related to our gift cards is included in deferred revenue-gift cards in our unaudited condensed consolidated balance sheets and includes the full value of unredeemed gift cards less the amortized portion of the breakage rates and the unamortized portion of third party fees. As of March 27, 2018 and December 26, 2017, our deferred revenue balance related to gift cards was approximately $104.7 million and $156.6 million, respectively. This change was primarily due to the redemption of gift cards partially offset by the sale of additional gift cards. We recognized sales of approximately $64.6 million for the 13 weeks ended March 27, 2018 related to the amount in deferred revenue as of December 26, 2017.

Franchise royalties include continuing fees received from our franchising of Texas Roadhouse restaurants. We execute franchise agreements for each franchise restaurant which sets out the terms of our arrangement with the franchisee. These agreements require the franchisee to pay ongoing royalties of generally 4.0% of gross sales from our domestic franchisees, along with royalties paid to us by our international franchisees. Franchise royalties are recognized as revenue as the corresponding franchisee restaurant sales occur.

Franchise fees are all remaining fees from our franchisees including initial fees, upfront fees from international agreements, fees paid to our domestic marketing and advertising fund, and fees for supervisory and administrative services. Our franchise agreements typically require the franchisee to pay an initial, non-refundable fee. Subject to our approval and payment of a renewal fee, a franchisee may generally renew the franchise agreement upon its expiration. These initial fees and renewal fees are deferred and recognized over the term of the agreement. We also enter into area development agreements for the development of international Texas Roadhouse restaurants. Upfront fees from development agreements are deferred and recognized on a pro-rata basis over the term of the individual restaurant franchise agreement as restaurants under the development agreement are opened. Our domestic franchise agreement also requires our franchisees to remit 0.3% of sales to our system-wide marketing and advertising fund. These amounts are recognized as revenue as the corresponding franchisee restaurant sales occur. Finally, we perform supervisory and administrative services for certain franchise restaurants for which we receive management fees, which are recognized as the services are performed. Total deferred revenue related to our franchise agreements is included in other liabilities in our unaudited condensed consolidated balance sheets and was approximately $1.2 million as of March 27, 2018 and December 26, 2017. We recognized revenue of approximately $0.1 million for the 13 weeks ended March 27, 2018 related to the amount in deferred revenue as of December 26, 2017.
