CY2011	us-gaap	Error Corrections And Prior Period Adjustments Description ErrorCorrectionsAndPriorPeriodAdjustmentsDescription	During the fourth quarter of 2011, we identified an error in the consolidated financial statements related to prior years. The error relates to the misapplication of accounting guidance related to the modifications of certain leases.  We concluded this adjustment, with a net impact of $0.2 million on our statement of operations for the fourth quarter of 2011, was not material to our results for the prior year periods or to the period of adjustment.  Accordingly, this cumulative change was recorded in the consolidated financial statements in the fourth quarter of 2011 as an out-of-period adjustment as follows:  a reduction to Net investment in direct financing leases of $17.6 million and an increase in net Operating real estate of $17.9 million on the consolidated balance sheet; and an increase in Lease revenues of $0.9 million, a reduction of Impairment charges of $1.6 million, and an increase in Depreciation expense of $2.2 million on the consolidated statement of operations.

At December 31, 2011 and 2010, none of the balances of our finance receivables were past due and we had not established any allowances for credit losses. Additionally, there have been no modifications of finance receivables. We evaluate the credit quality of our tenant receivables utilizing an internal 5-point credit rating scale, with 1 representing the highest credit quality and 5 representing the lowest.
