IPO Share Redemption Program
On March 30, 2018, our board of directors amended our IPO share redemption program. The key change to the IPO share redemption program is that after one year from the purchase date, a stockholder will be able to redeem at 100% of the NAV of the applicable share class. The amendment will take effect on May 2, 2018.
