Quarterly Report on Form 10-Q

Our quarterly report on Form 10-Q for the quarter ending September 30, 2015 has been filed with the SEC. The full 10-Q is available on our website under the Investors tab, SEC Filings. We are pleased to report that our 2015 third quarter funds from operations (“FFO”) was $182,000 (approximately 1 cent per share), as compared to $(170,000) in the third quarter of 2014; and our 2015 FFO for the nine months ending September 30 was $1,536,000 (approximately 7 cents per share), as compared to $(79,000) for the same period in 2014. FFO is a non-GAAP (Generally Accepted Accounting Principles) supplemental measure that is widely recognized as a measure of REIT operating performance. It is defined as net income or loss, computed in accordance with GAAP, excluding extraordinary items as defined by GAAP, and gains (or losses) from sales of property, plus depreciation and amortization on real estate assets, and after adjustments for unconsolidated partnerships, joint ventures, noncontrolling interests and subsidiaries. See our quarterly report on Form 10-Q for more details on this calculation and its reconciliation with GAAP.
