Portfolio Commentary In our March 26th Monthly Company Update we updated our Q1 2015 Core earnings outlook to be approximately $0.16 to $0.17 cents per common share outstanding and that for Q1 2015 we believe the Company will return $0.19 to $0.20 of capital per common share to shareholders (a non-taxable return of capital). We estimate that in April 2015 the Company will have a Core earnings rate of approximately $0.09 per share. The expected monthly cash dividend rate for Q2 2015 is $0.09 per share. Future month’s earnings will likely be in that context for the remainder of the quarter unless influenced by changes in amortization expense and funding rates, especially in the case of a change in the Fed Funds rate. Since the March 26th update, we have made the following portfolio and hedging changes: • Sale of $74.2 million of fifteen year 3% pass-throughs for regular April settle. • Sale of $75.9 million of DUS (Agency multi-family pools) for late April settle. • Termination of $120 million of swaps with a weighted average 98 months to maturity to parallel these bond sales. Last month we noted our purchase of $20 million of a non-performing loan securitization. This is an asset class which we will continue to study and potentially add to the portfolio over time. Following the settlements of the forward sales noted above, the Company estimates that 76.7% of the Company’s Agency and non-Agency REPO balance will be covered by swaps and 91.4% of the Company’s Agency securities will be covered by swaps. We believe that the majority of our non-Agency assets have limited hedging requirements because they either have low effective durations or high coupons. Of the $691.3 million swap book, $225 million or 32.5% are forward starting swaps that begin after Q2 2015, with all swaps commencing on or prior to March 2016. 3

Portfolio Commentary These changes have resulted in a current balance sheet duration of -0.37, a rates DV01 (dollar value of a basis point move in the entire curve assuming constant OAS, or option adjusted spread) of -$35,600 and a mortgage spread (OAS) DV01 of $487,000. The rates DV01 does not remain constant as rates go up. We estimate that an immediate 50 basis point move across the curve would make the DV01 change to -$1,100. Changes in DV01 for larger moves across the curve would likely not be linear. Since our March 26th report (which used asset prices and rate levels as of March 24th close of business), OAS on fifteen year pass- throughs that the Company owns have tightened by 9 basis points and the twenty year pass-throughs the Company owns have widened by 1 basis point of OAS. Spreads on the thirty year pass-throughs the Company owns widened by 2 basis points of OAS and the spreads on the DUS bonds the Company owns have remained relatively stable. Treasuries have rallied since March 26th with the ten-year down 10.4 basis points in yield. The “JMI” April 15th closing price of $7.87 is approximately 30% below our current book value estimates of $11.24 to $11.28 a share. If the Company produces Core earnings of $0.09 a month that would represent a 9.6% ROE on estimated current book value and a 13.7% return on the current stock price. The Company has not repurchased shares of common stock in the open market thus far in 2015. We do have Board authority to make repurchases. Insiders, which include the Company Board members and senior management, own a combined 339,883 of JMI shares. As a group, that would make the Insiders the Company’s third largest stockholder. 4
