In the realm of real estate investment trusts (REITs), Funds from Operations (FFO) serves as a more reliable metric than earnings. FFO takes into account the depreciation of real estate, which is added back in to determine a more accurate picture of a REIT's financial health. Additionally, any profits or losses from property sales are excluded from the calculation. In summary, FFO is a crucial tool in evaluating the performance of REITs and should not be overlooked.
