DEBT, NET

The Company enters into acquisition, development and construction debt agreements to purchase and develop real estate and for the construction of homes, which are generally secured primarily by the underlying real estate. Certain of the loans are funded in full at the initial loan closing and others are revolving facilities under which the Company may borrow, repay and redraw up to a specified amount during the term of the loan. Acquisition debt is due at various dates but is generally repaid when lots are released from the loans based upon a specific release price, as defined in each respective loan agreement, or the loans are refinanced at current prevailing rates. Construction and development debt is required to be repaid with proceeds from the sale of homes based upon a specific release price, as defined in each respective loan agreement.
