Adoption of ASC Topic 606, “Revenue from Contracts with Customers”

On December 29, 2017, we adopted Topic 606 using the modified retrospective method applied to those contracts that were not completed as of December 29, 2017. Results for reporting periods beginning after December 29, 2017 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605, Revenue Recognition (Topic 605).

We recorded a net increase to opening retained earnings of $7.8 million, net of tax, as of December 29, 2017 due to the cumulative impact of adopting Topic 606, with the impact primarily related to transactions for which we allow customers to store their merchandise at our retail stores for final delivery at a later date. The cumulative adjustment primarily resulted in a reduction of deferred revenue and related inventories and an increase to retained earnings. The impact to revenues as a result of applying Topic 606 was immaterial for the thirteen and thirty-nine weeks ended September 27, 2018.

Deferred Revenue

Under Topic 605 we recognized revenue for certain transactions for which we allow customers to store their merchandise at our retail stores for final delivery at a later date when both collection or reasonable assurance of collection of payment and final delivery of the product had occurred. Under Topic 605, the amount of revenue for which final delivery of the product had not occurred for these transactions was reflected in the Deferred revenue caption on the Consolidated Balance Sheet as of December 28, 2017. Under Topic 606, we evaluated the bill-and-hold criteria, and now recognize revenue at the point-of-sale, when the customer obtains control of the inventory. Amounts in Deferred revenue at period-end reflect orders for which the inventory is not currently ready for physical transfer to the customer.

Gift Card Breakage

Under Topic 605, gift card breakage income was recognized based upon historical redemption patterns. Under Topic 606, gift card breakage income is recognized in proportion to the pattern of rights exercised by the customer when we expect to be entitled to breakage. The timing and amounts of revenue related to gift card breakage income in the cumulative transition adjustment, and for the thirty-nine weeks ended September 27, 2018 were immaterial to the Consolidated Financial Statements.
