_____________

(a) In October 2012, the Company purchased defaulted debt securities, which were secured by residential real estate, for $18.6 million in cash. In fiscal 2015, the Company purchased the residential real estate parcel and all additional defaulted debt securities associated with the parcel for $19.9 million in cash, of which $5.1 million was allocated to the land and $14.8 million was allocated to the debt securities. The Company sold all of the debt securities to a third party for $35.8 million in January 2016. The resulting gain of $4.5 million on the sale is included in homebuilding other income in the consolidated statement of operations for fiscal 2016.

(b) Mortgage loans held for sale are reflected at fair value. Interest income earned on mortgage loans held for sale is based on contractual interest rates and included in financial services interest and other income. Mortgage loans held for sale at September 30, 2016 and 2015 include $6.8 million and $13.9 million, respectively, of loans for which the Company elected the fair value option upon origination and which the Company did not sell into the secondary market. Mortgage loans held for sale totaling $17.6 million and $4.7 million were transferred to Level 3 during fiscal 2016 and 2015, respectively, due to significant unobservable inputs used in determining the fair value of the loans. The fair value of these mortgage loans held for sale is generally calculated considering the secondary market and adjusted for the value of the underlying collateral, including interest rate risk, liquidity risk and prepayment risk. The Company plans to sell these loans as market conditions permit.

(c) Fair value measurements of these derivatives represent changes in fair value, as calculated by reference to quoted prices for similar assets, and are reflected in the balance sheet. Changes in these fair values during the periods presented are included in financial services revenues in the consolidated statements of operations.

Fair value measurements of assets on a non-recurring basis

The following table summarizes the Company’s assets measured at fair value on a nonrecurring basis at September 30, 2016 and 2015:

		Fair Value at September 30, 2016				Fair Value at September 30, 2015
	Balance Sheet Location	Level 2		Level 3		Level 3
		(In millions)
Homebuilding:

Inventory available for sale (a) (c)	Inventories	—		0.8		2.8
Financial Services and Other:

Other mortgage loans (a) (e)	Other assets	—		3.8		15.2
Real estate owned (a) (e)	Other assets	—		0.1		0.5

_____________

(a) The fair values included in the table above represent only those assets whose carrying values were adjusted to fair value in the respective period and were held at the end of the period.

(b) In performing its impairment analysis of communities, discount rates ranging from 10% to 14% were used in the periods presented.

(c) The fair value of inventory available for sale was determined based on recent offers received from outside third parties, comparable sales or actual contracts.

(d) These mortgage loans have some degree of impairment affecting their marketability. When available, quoted prices in the secondary market are used to determine fair value (Level 2); otherwise, a cash flow valuation model is used to determine fair value (Level 3).

(e) The fair values of other mortgage loans and real estate owned are determined based on the value of the underlying collateral.

(a) The fair value approximates carrying value due to its short-term nature, short maturity or floating interest rate terms, as applicable.

(b) The fair value is determined based on quoted market prices of recent transactions of the notes, which is classified as Level 2 within the fair value hierarchy.

(c) As described in Note A, the assets and liabilities of certain subsidiaries were reclassified from the Company’s homebuilding section of its balance sheet to the financial services and other section of its balance sheet during fiscal 2016. The prior year amounts have been reclassified to conform to the current year presentation.
