Commitments and Contingencies	Commitments and Contingencies Legal From time to time, the Company is party to various lawsuits, claims and other legal proceedings arising out of, or incident to, our ordinary course of business. Management believes, based in part upon consultation with legal counsel, that the ultimate resolution of all such claims will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. As of June 30, 2015, the risk of material loss from such legal actions impacting the Company’s financial condition or results from operations has been assessed as remote. Concentrations As of June 30, 2015, the majority of the Company’s properties were located in California, which exposes the Company to greater economic risks than if it owned a more geographically dispersed portfolio. Further, for the six months ended June 30, 2015 and 2014, approximately 8% and 16%, respectively, of the Company’s revenues were derived from tenants in the media and entertainment industry, which makes the Company susceptible to demand for rental space in such industry. Consequently, the Company is subject to the risks associated with an investment in real estate with a concentration of tenants in that industry.
