We believe that a quantitative reconciliation of such forward-looking information to the most directly comparable GAAP financial measure cannot be made available without unreasonable efforts, because a reconciliation of these non-GAAP financial measures would require an estimate of future non-operating items such as impairment charges or gain/loss on property dispositions. Neither the timing nor likelihood of these events, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, a reconciliation of such forward-looking information to the most directly comparable GAAP financial measure is not provided.
