Direct Financing Lease Conversion
During the first quarter of 2019, the Company converted a DFL portfolio of 14 senior housing triple-net properties, previously on “Watch List” status, to a RIDEA structure, requiring the Company to recognize net assets equal to the lower of the net assets’ fair value or the carrying value of the net investment in the DFL. As a result, the Company derecognized the $351 million carrying value of the net investment in DFL related to the 14 properties and recognized a combination of net real estate ($331 million) and net intangibles assets ($20 million) for the same aggregate amount, with no gain or loss recognized. As a result of the transaction, the 14 properties were transitioned from the senior housing triple-net segment to the SHOP segment during the first quarter of 2019.
Direct Financing Lease Sale
During the second quarter of 2019, the Company entered into agreements to sell 13 senior housing facilities under DFLs (the “DFL Sale Portfolio”) for $274 million. Upon entering into the agreements, the Company recognized an allowance for DFL losses and related impairment charge of $10 million to write-down the carrying value of the DFL Sale Portfolio to its fair value. The fair value of the DFL Sale Portfolio was based upon the agreed on sale price, less estimated costs to sell, which is considered to be a Level 2 measurement within the fair value hierarchy. In conjunction with the entering into agreements to sell the DFL Sale Portfolio, the Company placed the portfolio on nonaccrual status and began recognizing income equal to the amount of cash received.
The Company completed the sale of the DFL Sale Portfolio in September 2019.
