[1] In October 2012, the Company purchased defaulted debt securities which are secured by residential real estate. These securities, which are included in other assets in the consolidated balance sheets, are classified as available for sale and are reflected at fair value. The fair value of these securities was determined by estimating the future cash flows of the securities and the residential real estate utilizing discount rates of 6% and 18%, respectively. Unrealized gains or losses on these securities, net of tax, are recorded in accumulated other comprehensive income (loss) in the consolidated balance sheets. The Company has entered into an agreement to purchase this residential real estate parcel and all additional defaulted debt securities associated with the parcel, in order to develop the property and build and sell homes. In April 2015, the Company completed this purchase transaction for $19.6 million in cash. The purchase price will be allocated to the land and the debt securities acquired in the third quarter of fiscal 2015.
