[1] During the thirteen week period ended September 26, 2018 we completed sale leaseback transactions of 141 company-owned Chili’s restaurant properties. As part of this transaction, we sold the related restaurant fixed assets totaling $166.6 million, net of accumulated depreciation. Additionally, Chili’s recognized $20.1 million of gain on the sale, including a certain portion of the deferred gain, as well as transaction related costs incurred totaling $6.8 million in Other (gains) and charges on Consolidated Statements of Comprehensive Income. Please see Note 3 - Sale Leaseback Transactions for further details.

[2] Deferred income taxes, net adjustment relates to the net change in liabilities and equity as a result of the adoption of ASC 606 described in notes ⁽²⁾ and ⁽³⁾ below.

[3] Gift card liability is adjusted for the ASC 606 adoption impact of the change to recognize gift card breakage proportionate to the pattern of related gift card redemption. Under Legacy GAAP, gift card breakage was recognized when the likelihood of redemption was deemed remote. The cumulative effect of applying ASC 606 accounting to gift card balances outstanding at June 28, 2018 resulted in an $8.2 million decrease in Gift card liability due to the change in timing of recognition between ASC 606 and Legacy GAAP, and a corresponding $2.0 million decrease in Deferred income taxes, net, and a $6.2 million increase in Retained earnings.

[4] Other liabilities $16.6 million and Other accrued liabilities $1.5 million adjustments relate to the deferral of previously recognized franchise and development fees received from franchisees, with a corresponding $4.5 million increase in Deferred income taxes, and a $13.6 million decrease to Retained earnings at June 28, 2018.
