[1] The balance at August 31, 2019 reflects a change in the classification of certain community sales office and other marketing- and model home-related costs and related accumulated amortization from inventories to property and equipment, net due to our adoption of ASC 606 effective December 1, 2018, as described in Note 1 – Basis of Presentation and Significant Accounting Policies.

[2] In January 2019, we completed the sale and leaseback of our office building in San Antonio, Texas. The sale generated net cash proceeds of $5.8 million and a gain of $2.2 million, which will be recognized on a straight-line basis over a 10-year lease term until our adoption of ASC 842, when the remaining gain will be recognized as a transition adjustment to retained earnings.
