Bloomberg L.P. (“Bloomberg”) accounted for $46,586,000 and $44,483,000, representing approximately 45% of our totalrevenues in each of thesix-month periods ended June 30, 2015and 2014, respectively. No other tenant accounted for more than 10% of our total revenues. If we were to lose Bloomberg as a tenant, or if Bloomberg were to be unable to fulfill its obligations under its lease, it would adversely affect our results of operations and financial condition. In order to assist us in our continuing assessment of Bloomberg's creditworthiness, we receive certain confidential financial information and metrics from Bloomberg. In addition, we access and evaluate financial information regarding Bloomberg from other private sources, as well as publicly available data.

In October 2014, Bloomberg exercised its option to extend leases that were scheduled to expire in December 2015 covering 188,608 square feet of office space at our 731 Lexington Avenue property for a term of 5 years. We are currently in negotiations with Bloomberg to determine the rental rate for the extension period.
