Performance Graph The following graph compares the yearly change in the cumulative total stockholder return for our last five full fiscal years, based upon the market price of our common stock, with the cumulative total return on a NASDAQ Composite Index (U. S.  Companies) and a peer group, the NASDAQ Medical Equipment-SIC Code 3840-3849 Index, which is comprised of medical equipment companies, for that period.
The performance graph assumes the investment of $100 on March 31, 2010 in our Common Stock, the NASDAQ Composite Index (U. S.  Companies) and the peer group index, and the reinvestment of any and all dividends.

Transfer Agent American Stock Transfer & Trust Company, 59 Maiden Lane, New York, NY 10038, is our stock Transfer Agent.
We employ sales associates who are paid salaries, commissions or both to complete on-site sales of homes.
We also sell homes through independent brokers.
We advertise our communities in newspapers, radio advertisements and other local and regional publications, on billboards and on the Internet, including our website, www.
lennar.
com.
In addition, we advertise our active adult communities in areas where prospective active adult homebuyers live.
We have historically participated in charitable down-payment assistance programs.
Through these programs, we made donations to non-profit organizations that provided financial assistance to a homebuyer who would not otherwise have sufficient funds for a down payment.
During 2008, 35% of our homebuyers utilized the charitable down-payment assistance programs.
The FHA Modernization Act of 2008 eliminated these programs after September 30, 2008 and their elimination has had an adverse impact on home sales since that point.
Quality Service We strive to continually improve homeowner customer satisfaction throughout the pre-sale, sale, construction, closing and post-closing periods.
Through the participation of sales associates, on-site construction supervisors and customer care associates, all working in a team effort, we strive to create a quality homebuying experience for our customers, which we believe leads to enhanced customer retention and referrals.
The quality of our homes is substantially affected by the efforts of on-site management and others engaged in the construction process, by the materials we use in particular homes or by other similar factors.
To the extent bonuses have been paid, management incentives programs have consistently been contingent upon achieving certain customer satisfaction standards.
We warrant our new homes against defective materials and workmanship for a minimum period of one year after the date of closing.
Although we subcontract virtually all segments of construction to others and our contracts call for the subcontractors to repair or replace any deficient items related to their trades, we are primarily responsible to the homebuyers for the correction of any deficiencies.
Deliveries The table below indicates the number of deliveries for each of our homebuilding segments and Homebuilding Other during our last three fiscal years:
## Table 1 ##
Of the total home deliveries listed above, 391, 1,701 and 2,536, respectively, represent deliveries from unconsolidated entities for the years ended November 30, 2008, 2007 and 2006.
Backlog Backlog represents the number of homes under sales contracts.
Homes are sold using sales contracts, which are generally accompanied by sales deposits.
In some instances, purchasers are permitted to cancel sales contracts if they fail to qualify for financing or under certain other circumstances.
We experienced a cancellation rate of 26% in 2008, compared to 30% and 29%, respectively, in 2007 and 2006.
Substantially all homes currently in backlog will be delivered within fiscal year 2009.
We do not recognize revenue on homes under sales contracts until the sales are closed and title passes to the new homeowners, except for our multi-level residential buildings under construction for which revenue was recognized under percentage-of-completion accounting during 2006 and 2007.
In 2008, we stopped recognizing revenues and expenses under percentage-of-completion accounting for our multi-level residential buildings under construction as a result of Emerging Issues Task Force 06-8, Applicability of the Assessment of a Buyer’s Continuing Investment under FASB Statement No.66 for Sales of Condominiums (“EITF 06-8”) (see Note 1 in Item 8 of this Report).
LENNAR CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) surrendered.
The surrender is reflected as a reduction in stockholders’ equity equal to the fair value of the restricted stock when it was issued, with an offsetting increase in stockholders’ equity to reflect a deferral of the compensation expense related to the surrendered restricted stock.
Changes in the fair value of the shares that will be issued in the future are not reflected in the consolidated financial statements.
As of November 30, 2007, approximately 36,000 Class A common shares and 3,600 Class B common shares of restricted stock had been surrendered in exchange for rights under the Deferred Compensation Plan, resulting in a reduction in stockholders’ equity of $0.3 million fully offset by an increase in stockholders’ equity to reflect the deferral of compensation in that amount.
Shares that the Company is obligated to issue in the future under the Deferred Compensation Plan are treated as outstanding shares in both the Company’s basic and diluted earnings (loss) per share calculations for the years ended November 30, 2007 and 2006.
In 2008, the Compensation Committee of the Company’s Board of Directors approved the termination of the Deferred Compensation Plan and $1.8 million in total in cash and shares of common stock was distributed to its participants.15.
Financial Instruments The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at November 30, 2008 and 2007, using available market information and what the Company believes to be appropriate valuation methodologies.
Considerable judgment is required in interpreting market data to develop the estimates of fair value.
Accordingly, the estimates presented are not necessarily indicative of the amounts that the Company could realize in a current market exchange.
The use of different market assumptions and/or estimation methodologies might have a material effect on the estimated fair value amounts.
The table excludes cash, restricted cash, receivables and accounts payable, which had fair values approximating their carrying amounts due to the short maturities of these instruments.
## Table 2 ##
The following methods and assumptions are used by the Company in estimating fair values: Homebuilding—For senior notes and other debts payable, the fair value of fixed-rate borrowings is based on quoted market prices.
The Company’s variable-rate borrowings are tied to market indices and approximate fair value due to the short maturities associated with the majority of the instruments.
Financial services—The fair values above are based on quoted market prices, if available.
The fair values for instruments that do not have quoted market prices are estimated by the Company on the basis of discounted cash flows or other financial information.
