The following disclosure is added at the end of the section entitled “Description of Real Estate Investments — Recent Property Acquisitions — 570 Seventh Avenue,” as included in Supplement No.14.

“123 William Street

On March 27, 2015, we acquired the fee simple interest in an institutional-quality office building located at 123 William Street in downtown Manhattan.

The seller of the property was EEGO 123 William Owner, LLC. The seller is a wholly owned subsidiary of EEGO-ARC 123 William JV, LLC, a joint venture in which New York REIT, Inc. (“NYRT”) held a $35.1 million preferred equity interest. The sponsor of NYRT is also the sponsor of the Company.

Capitalization

The contract purchase price of the property was $253.0 million, exclusive of closing costs. We funded the purchase price with proceeds from our ongoing initial public offering and a loan from Capital One, National Association as Administrative Agent for the other lenders thereto. In connection with the acquisition of the property, we paid our advisor $5.9 million in acquisition fees.

S-3

Other

We believe the property is suitable and adequate for its uses.

We anticipate making approximately $5.2 million in additional investments in the property to modernize the elevator system. We intend to fund the additional investment with proceeds from our ongoing initial public offering.

We believe the property is adequately insured.

The Federal tax basis and the rate of depreciation will be determined based upon the completion of cost allocation studies in connection with finalizing our 2015 Federal tax return.

The annual real estate taxes payable on the property for the current tax year are expected to be $4.0 million, at a rate of 10.684%.

We believe that the property is well located, has acceptable roadway access and is well maintained. The property is subject to competition from similar properties within its respective market area and the economic performance of the tenants of the property and their operations could be affected by changes in local economic conditions. We did not consider any other factors material or relevant to the decision to acquire the property, nor, after reasonable inquiry, are we aware of any material factors other than those discussed above that would cause the reported financial information not to be necessarily indicative of future operating results.

Financial Obligations

Capital One Loan

On March 27, 2015, the Company, through a wholly owned subsidiary of the OP, entered into a loan agreement (the “Loan”) with Capital One, National Association, as Administrative Agent for the lender thereto, for a maximum amount of $110.0 million in connection with the Company’s acquisition of the Property. The Loan bears interest at a rate of one month LIBOR plus 2.25% and requires monthly interest payments, with the principal balance due on the maturity date in March 2017 with a one-time option to extend for one year. The Loan is nonrecourse, may be accelerated only in the event of a default and may be prepaid, in whole or in part, without penalty.”
