RECENT DEVELOPMENTS

Reallocation of Shares

In May 2013, we commenced our primary offering of up to $1.4 billion in shares of our common stock, including $400.0 million in shares of common stock through our distribution reinvestment plan (“DRIP”).    In May 2014, we announced the termination of sales of our Class A common stock on June 30, 2014 and the potential reallocation of up to $250.0 million of shares registered under our DRIP to our primary offering.  In June 2014, we determined to reallocate the full $250.0 million in shares from the DRIP.

We plan to continue to offer shares of our Class C common stock and offer shares under our DRIP beyond the termination of sales of the Class A shares on June 30, 2014.  As of June 10, 2014, we have issued 84,847,578 Class A Shares ($847,026,328) and 6,787,107 Class C Shares ($63,459,454) in connection with our offering raising aggregate gross proceeds of $910,485,782. In addition, we have issued 406,104 Class A Shares ($3,898,598) and 68,007 Class C Shares ($610,705) through our DRIP.

Prior Programs

The paragraph in the “Prior Programs — Liquidity Events” section on page 97 of our Prospectus is superseded in its entirety by the following:

In January 2014, CPA®:16 — Global merged with W. P. Carey as a liquidity event for its stockholders, which was within the time frame for a liquidity event disclosed in CPA®:16 — Global’s offering materials. The average annual return for CPA®:16 — Global was 7.64%. A stockholder that acquired 1,000 shares of CPA®:16 — Global in its initial public offering and held those shares through its January 2014 merger with W. P. Carey received a total value of $17,469, which is comprised of the value of the shares of W. P. Carey received in the merger of $11,373 (based on the $62.15 average closing price of W. P. Carey stock for the 30 days after the closing of the merger) and total cash distributions paid of $6,276. The offering materials for each of CPA®:17 — Global and CWI disclose anticipated timeframes for their boards to seek liquidity alternatives; however, such timeframe has not yet occurred. In no case did the offering materials establish an absolute deadline for completing a liquidity event.
