RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

(in thousands, except per share data)

Earnings before interest, taxes, depreciation and amortization, or EBITDA, and EBITDA excluding certain items are not financial measures determined according to U.S. generally accepted accounting principles, or GAAP. We consider EBITDA and EBITDA excluding certain items to be a meaningful disclosure because we believe that the inclusion of these non-GAAP financial measures may help investors to gain a better understanding of changes in our operating results, and can also help investors who wish to make comparisons between us and other companies on both a GAAP and a non-GAAP basis. EBITDA and EBITDA excluding certain items as presented may not, however, always be comparable to amounts calculated by other companies. These non-GAAP financial measures are used by management to evaluate financial performance and resource allocation for our communities and for us as a whole and for comparing such performance to that of prior periods and to the performance of our competitors. This information should not be considered as an alternative to net income or any other financial operating or performance measure established by GAAP. The reconciliation of income from continuing operations to EBITDA and EBITDA excluding certain items is as follows:
