Risk Factors

The following disclosure hereby replaces the risk factor entitled “Recent disclosures made by American Realty Capital Properties, Inc., or ARCP, an entity previously sponsored by the parent of our sponsor, regarding certain accounting errors have led to the temporary suspension of selling agreements by certain soliciting dealers,” as added by Supplement No. 12 to the Prospectus.

“Disclosures made by American Realty Capital Properties, Inc., or ARCP, an entity previously sponsored by the parent of our sponsor may adversely affect our ability to raise substantial funds.

Beginning in October 2014, and including disclosures made on March 2, 2015, ARCP, an entity previously sponsored by the parent of our sponsor has disclosed various items that have had a material adverse effect on its business, results of operations and financial condition. These items include the need to restate previously issued financial statements that were intentionally not corrected, a lack of effective internal control over financial reporting and disclosure controls and procedures as well as the presence of various regulatory investigations. See “Prior Performance Summary — Adverse Business Developments and Conditions.”

Since the initial announcement in October, a number of participating broker-dealers temporarily suspended their participation in the distribution of our offering. Although certain of these broker-dealers have reinstated their participation, we cannot predict the length of time the remaining temporary suspensions will continue or whether all participating broker-dealers will reinstate their participation in the distribution of our offering.

Description of Portfolio Investments

The following disclosure is hereby added as the first full paragraph under the subheading “Portfolio Investments” on page 142 of the Prospectus.

“Stony Point Shopping Center Mortgage Loan

On January 30, 2015, we, through our operating partnership, originated a mortgage loan in the total original principal amount of $12.75 million (including a future funding component of $1.3 million) secured by a first priority mortgage on the fee interest in the Stony Point Shopping Center located in Richmond, Virginia. Stony Point Shopping Center, built in 1984 and renovated between 2010 and 2014, is an 85% occupied, 112,779 square foot neighborhood retail center located at the corner of Huguenot and Stony Point Road and is anchored by Martin’s Food Market. The anchor tenant, or its predecessor Ukrop’s Grocery Store, has been located at the property since its construction and the store currently features strong sales. The property has an “as-is” appraised value of $15.3 million as of December 18, 2014. Based upon such appraisal and the initial funding of $11.45 million, the mortgage loan represents a 75% loan-to-value ratio. At closing, the underwritten cash flow available for debt service (net operating income less reserves) exceeds forward debt

S-4

service payments related to the property by 1.92x (calculated by dividing cash flow available for debt service by the projected annual debt service to be paid in connection with the mortgage loan for the next year).

The mortgage loan has an initial term of four years, subject to a one-year extension option, the exercise of which is conditioned upon the borrower’s satisfaction of certain financial tests and other requirements. The mortgage loan (requiring monthly payments of interest only) bears interest at a floating rate equal to 1-month LIBOR plus 4.50% per annum, subject to interest rate increases in the case of a default.”

The following disclosure hereby replaces in its entirety the last paragraph in the section entitled “Adverse Business Developments and Conditions” under “Programs of Our Sponsor” on page 171 of the Prospectus.

“On October 29, 2014, ARCP announced that its audit committee had concluded that the previously issued financial statements and other financial information contained in certain public filings should no longer be relied

S-5

upon. This conclusion was based on the preliminary findings of an investigation conducted by ARCP’s audit committee which concluded that certain accounting errors were made by ARCP personnel that were not corrected after being discovered, resulting in an overstatement of AFFO and an understatement of ARCP’s net loss for the three and six months ended June 30, 2014. ARCP also announced the resignation of its chief accounting officer and its chief financial officer. ARCP’s former chief financial officer also is one of the non-controlling owners of the parent of our sponsor, but does not have a role in managing our business or our sponsor’s business. In December 2014, ARCP announced the resignation of its executive chairman, who was also the chief executuive officer and chairman of our board of directors until his resignation on November 17, 2014. This individual also is currently one of the controlling members of the parent of our sponsor.

On March 2, 2015, ARCP announced the completion of its audit committee’s investigation and filed amendments to its Form 10-K for the year ended December 31, 2013 and its Form 10-Q for the quarters ended March 31, 2014 and June 30, 2014, which are available at the internet site maintained by the SEC,www.sec.gov. According to these filings, these amendments corrected errors in ARCP’s financial statements and in its calculation of AFFO that resulted in overstatements of AFFO for the years ended December 31, 2011, 2012 and 2013 and the quarters ended March 31, 2013 and 2014 and June 30, 2014 and described certain results of its investigations, including matters relating to payments to, and transactions with, affiliates of the parent of our sponsor and certain equity awards to certain officers and directors. In addition, ARCP disclosed that the audit committee investigation had found material weaknesses in ARCP’s internal control over financial reporting and its disclosure controls and procedures. ARCP also disclosed that the SEC has commenced a formal investigation, that the United States Attorney’s Office for the Southern District of New York contacted counsel for both ARCP’s audit committee and ARCP with respect to the matter and that the Secretary of the Commonwealth of Massachusetts has issued a subpoena for various documents.

Other than as disclosed above, there have been no major adverse business developments or conditions experienced by any program or non-program property that would be material to investors, including as a result of recent general economic conditions.”
