(NYSE: BXP) today reported results for the second quarter ended June 30, 2001. Funds from Operations (FFO) for the quarter ended June 30, 2001 were $81.4 million, or $0.90 per share basic and $0.86 per share diluted before an accounting charge of approximately ($0.04) per share on a diluted basis related to the application of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" for the quarter ended June 30, 2001. FFO for the quarter includes a charge of $6.5 million or $0.05 per share resulting from the write-down of the Company's equity investments ("Technology Investments") in Allied Riser (NASDAQ:ARCC) and Cypress Communications (NASDAQ:CYCO). After this write-down, the Company's only remaining Technology Investment is a $4.3 million investment in Captivate Network Inc., a privately held company. FFO for the second quarter of 2001 compares to FFO of $59.3 million, or $0.87 per share basic and $0.83 per share diluted for the quarter ended June 30, 2000. Excluding the Technology Investment write-down, and the charges related to SFAS 133, this represents a 9.6% year to year increase in diluted FFO per share. The weighted average number of basic and diluted shares outstanding totaled 89,989,616 and 105,259,081, respectively, for the quarter ended June 30, 2001 and 67,991,227 and 82,582,547, respectively, for the same quarter last year.
