ADDITIONAL MEASURES OF PERFORMANCE
Funds From Operations (“FFO”) and Adjusted Funds From Operations (“AFFO”)
We believe that FFO and AFFO, in addition to net income (loss) and cash flows from operating activities as defined by GAAP, are useful supplemental performance measures that our management uses to evaluate our consolidated operating performance. However, these supplemental, non-GAAP measures should not be considered as alternatives to net income (loss) or to cash flows from operating activities as indications of our performance and are not intended to be used as liquidity measures indicative of cash flow available to fund our cash needs, including our ability to make distributions to our stockholders. No single measure can provide users of financial information with sufficient information and only our disclosures read as a whole can be relied upon to adequately portray our financial position, liquidity, and results of operations. In addition, other REITs may define FFO, AFFO, and similar measures differently and choose to treat certain accounting line items in a manner different from us due to specific differences in investment and operating strategy or for other reasons.
FFO. As defined by the National Association of Real Estate Investment Trusts (“NAREIT”), FFO is a non-GAAP measure that excludes certain items such as real estate-related depreciation and amortization. We believe FFO is a meaningful supplemental measure of our operating performance that is useful to investors because depreciation and amortization in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. By excluding gains or losses on the sale of assets, we believe FFO provides a helpful additional measure of our consolidated operating performance on a comparative basis. We use FFO as an indication of our consolidated operating performance and as a guide to making decisions about future investments.
AFFO. AFFO further adjusts FFO to reflect the performance of our portfolio by adjusting for items we believe are not directly attributable to our operations. Our adjustments to FFO to arrive at AFFO include removing the impact of (i) our performance participation allocation, (ii) unrealized (gain) loss from changes in fair value of financial instruments, and (iii) financing obligation liability appreciation (depreciation).
Although some REITs may present certain performance measures differently, we believe FFO and AFFO generally facilitate a comparison to other REITs that have similar operating characteristics to us. We believe investors are best served if the information that is made available to them allows them to align their analyses and evaluation with the same performance metrics used by management in planning and executing our business strategy. Neither the SEC, NAREIT, nor any regulatory body has passed judgment on the acceptability of the adjustments used to calculate FFO or AFFO. In the future, the SEC, NAREIT, or a regulatory body may decide to standardize the allowable adjustments across the non-traded REIT industry at which point we may adjust our calculations and characterizations of FFO and AFFO.
