    The ratios presented in this table have been adjusted to reflect our home services
operations (sold in April 2008), Construction Services (sold in March 2007), Home Equity
(sold in July 2006), International Homebuilding (sold in September 2005), Construction
Products (spun off in January 2004), and Manufactured Homes (spun off in June 2003) as
discontinued operations.(2)
    
    Earnings (Loss) from Continuing Operations are Before Income Taxes and Cumulative Effect of
a Change in Accounting Principle adopted in fiscal 2004.(3)
    
    Excludes interest related to our unrecognized tax benefits as such interest is included as a
component of the income tax provision.(4)
    
    Represents a supplemental presentation that reflects the Financial Services segment as if
accounted for under the equity method. We believe that separate disclosure of the
consolidating information is useful because the Financial Services subsidiaries operate in a
distinctly different financial environment that generally requires significantly less equity
to support their higher debt levels compared to the operations of our other subsidiaries; the
Financial Services subsidiaries have structured their financing programs substantially on a
stand alone basis; and we have limited obligations with respect to the indebtedness of our
Financial Services subsidiaries. Management uses this information in its financial and
strategic planning. We also use this presentation to allow investors to compare us to
homebuilders that do not have financial services operations.(5)
    
    Earnings were inadequate to cover fixed charges for the six months ended September 30, 2008
and 2007 and for the fiscal year ended March 31, 2008.
