Homes under construction include homes that are in various stages of construction. As of December 31, 2012 and 2011, we had 649 homes (with a carrying value of $89.8 million) and 573 homes (with a carrying value of $85.5 million), respectively, included in homes under construction that were not subject to a sales contract. Model homes and furnishings include homes that are under construction or have been completed and are being used as sales models. The amount also includes the net book value of furnishings included in our model homes. Depreciation on model home furnishings is recorded using an accelerated method over the estimated useful life of the assets, typically three years. The Company assesses inventory for recoverability on a quarterly basis. Refer to Notes 1 and 3 of our Consolidated Financial Statements for additional details relating to our procedures for evaluating our inventories for impairment. Land purchase deposits include both refundable and non-refundable amounts paid to third party sellers relating to the purchase of land. On an ongoing basis, the Company evaluates the land option agreements relating to the land purchase deposits. In the period during which the Company makes the decision not to proceed with the purchase of land under an agreement, the Company writes off any deposits and accumulated pre-acquisition costs relating to such agreement.
