11. CAPITALIZED INTEREST AND REAL ESTATE TAXES

Interest and real estate taxes incurred relating to the development of lots and parcels are capitalized to real estate inventories during the active development period, which generally commences when borrowings are used to acquire real estate assets and ends when the properties are substantially complete or the property becomes inactive. A project becomes inactive when development and construction activities have been suspended indefinitely. Interest is capitalized based on the interest rate applicable to specific borrowings or the weighted average of the rates applicable to other borrowings during the period. Interest and real estate taxes capitalized to real estate inventories are expensed as a component of cost of sales as related units are sold.

The following table is a summary of interest and real estate taxes incurred and capitalized and interest and real estate taxes expensed for units settled:
