    The ratios presented in this table have been adjusted to reflect our sub-prime home
equity lending operations, international homebuilding operations (sold in September 2005),
Centex Construction Products, Inc. (spun off in January 2004), and our manufactured housing
operations (spun off in June 2003) as discontinued operations.(2)
    
    Earnings from Continuing Operations are Before Income Taxes and Cumulative Effect of a
Change in Accounting Principle adopted in fiscal 2004.(3)
    
    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.
