FFO does not represent cash generated from operating activities in accordance with GAAP and is not indicative of cash available to fund cash needs . FFO should not be considered as an alternative to net income as an indicator of our operating performance or as an alternative to cash flow as a measure of liquidity.Lexington includes in its calculation of FFO , which Lexington refers to as the " Company 's funds from operations " or " Company FFO , " Lexington 's operating partnership units and Lexington 's Series C Cumulative Convertible Preferred Shares because these securities are convertible , at the holder 's option , into Lexington 's common shares . Management believes this is appropriate and relevant to securities analysts , investors and other interested parties because Lexington presents Company FFO on a company-wide basis as if all securities that are convertible , at the holder 's option , into Lexington 's common shares , are converted . Since others do not calculate FFO in a similar fashion , Company FFO may not be comparable to similarly titled measures as reported by others .
