Recent Developments ▪ On June 30, 2017, we modified our credit line with Bankwell Bank, our lender, to, among other things: • Increase the amount of the facility from $15 million to $20 million to increase our ability to fund mortgage loans. • Modify the method of calculating the interest rate on the outstanding balance. As a result of this modification, as of July 1, 2017, the interest rate on the Bankwell Credit Line is 5.8% compared to 7.25% per annum immediately before this modification . ▪ We have declared dividends for our first two quarters as a public company: • We paid a dividend of $0.05 per share on April 27, 2017, for the half - quarter period from our IPO through March 31, 2017 . • We declared a dividend of $0.105 per share for the quarter ended June 30, 2017, payable on July 27, 2017 to shareholders of record on July 17, 2017.
