[1] Does not include interest incurred by our mortgage and finance subsidiaries.
[2] Other interest expensed is comprised of interest that does not qualify for capitalization because our assets that qualify for interest capitalization (inventory under development) do not exceed our debt. Interest on completed homes and land in planning which does not qualify for capitalization is expensed.
[3] Cash paid for interest, net of capitalized interest, is the sum of other interest expensed, as defined above, and interest paid by our mortgage and finance subsidiaries adjusted for the change in accrued interest.
[4] Capitalized interest amounts are shown gross before allocating any portion of impairments to capitalized interest.
