Good morning, and welcome to the Q2 2022 earnings conference call for Bimini Capital Management. This call is being recorded today, August 12, 2022. At this time, the company would like to remind the listeners that statements made during today's conference call relating to matters that are not historical facts are forward-looking statements subject to safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Listeners are cautioned that such forward-looking statements are based on information currently available on the management's good faith belief with respect to future events and subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in such forward-looking statements.
Important factors that could cause such differences are described in the company's filings with the Securities and Exchange Commission, including the company's most recent annual report on Form 10-K.
The company assumes no obligation to update such forward-looking statements to reflect actual results, changes in assumptions, or changes in other factors affecting forward-looking statements. Now I'd like to turn the conference over to the company's chairman and chief executive officer, Mr. Robert E. Cauley. Please go ahead, sir.
Thank you, operator, and good morning. Good morning, and thank you for joining us to discuss Bimini's Q2 2022 results. I'm going to give you a brief overview of the economic backdrop we faced during the quarter and then discuss our results. During the latter part of the Q2 of 2022, inflation data drove a material change in Fed policy, interest rates, and the outlook for the economy. This was the catalyst for the Fed to pivot even more forcefully than they did during the late 2020, 2021, early 2022 period to address high inflation by raising the Fed funds rate 200 basis points collectively at the May, June, and July meetings. The market expects the Fed to continue raising the Fed funds rate by at least another 100 basis points by year-end.
Increases in the Fed funds rate are likely to affect economic activity, and the Fed has acknowledged their actions may lead to a recession. Sectors of the economy most sensitive to interest rates, such as housing, have already started to slow. The market appears to anticipate the Fed will be able to contain inflation and that the result will be a contraction in economic growth. The combined effect, more increases to the Fed funds rate and the presumption inflation will ultimately be contained by the Fed, albeit potentially at the expense of a recession, has caused the yield curve to invert, whereby short maturity US Treasuries yield more than long-term US Treasuries. This condition may persist for the balance of 2022 and into 2023.
Given these developments in the fixed income markets and the poor performance of agency RMBS in particular, Orchid Island Capital reported a Q2 2022 loss of $60.1 million, and its shareholders' equity declined from $592.4 million as of March 31, 2022, to $506.4 million as of June 30, 2022. The market conditions described above drove the loss as agency RMBS underperformed comparable duration Treasuries in Orchid's hedge position. The decline in shareholders' equity may lead to reduced management fees at Bimini Advisors in the near term since the management fees are a function of Orchid's equity.
Orchid also reduced its monthly dividend twice during the Q1, so monthly dividend revenues on the company's approximately 2.5 million shares declined from approximately $402.3 thousand to approximately $350.4 thousand during the Q2. However, as the Q3 unfolds, Orchid has appeared to weather the current market condition and is poised to capitalize on the attractive returns that have become available. On Orchid's Q2 earnings call last week, it was reported that Orchid's book value had recovered by 5% or more so far in the Q3. Our advisory service revenues during the Q2 of 2022 of $3.3 million were 52% higher than the Q2 of 2021.
Year-to-date revenues of $6.4 million are also 52% higher than the comparable period last year, reflecting a year-over-year increase in Orchid shareholders' equity despite the decline during the Q2 of 2022. The increase in advisory service revenue also reflects fees from Orchid related to repurchase agreement funding, settlement, and margin maintenance services that we now perform for Orchid effective April 1, 2022. With respect to the RMBS portfolio, as we discussed at the end of the Q1, we took steps to reduce the RMBS portfolio at Royal Palm Capital in response to adverse market conditions. In fact, the agency RMBS portfolio at Royal Palm Capital decreased during the Q2 of 2022 by $16.1 million.
The combined effect of net sales of $12.3 million, $2.1 million of pay downs and return on investment on the structured securities portfolio, and $1.7 million of net realized and unrealized mark-to-market losses. As the Q2 of 2022 unfolded, our intention was to grow our cash position until we saw clear evidence the market had stabilized before redeploying our cash to resume growing the portfolio. To date, the agency RMBS market has recovered somewhat during the Q3 of 2022, and we will likely begin to rebuild the portfolio over the balance of the quarter. Given the high cash balances that must be maintained for a hedged and levered RMBS portfolio, due mainly to margin call activity with both the portfolio and our hedges, we will be somewhat constrained in how aggressively we build the portfolio.
The combined portfolio and advisory services revenue segments we operate at our Royal Palm Capital subsidiary have generated approximately $1.6 million of taxable income year to date. As our strategy is focused on utilizing our significant tax net operating losses, we want to focus on remaining cash flow positive and maximizing our taxable income as we move forward. For this reason, we'll be conservative in growing the portfolio. As an alternative to RMBS assets, we occasionally consider adding to our Orchid shareholdings when the stock is trading at attractive levels, but do not have unlimited capacity to do so. We currently operate under an exemption from regulation as an investment company under the Investment Company Act of 1940 as our assets primarily consist of quote-unquote, "Qualifying assets," which are mortgage-backed securities.
Because Orchid shares are not considered qualifying assets, we are limited in the amount of Orchid stock we can own and maintain our current exempt status. As of June 30, 2022, Orchid shares represented approximately 7.9% of Bimini's total assets of approximately $93.3 million. The company pursued an exemption from regulation under the act from the Securities and Exchange Commission that would allow the company to materially increase its holdings of shares of Orchid Island Capital. However, the exemption was not granted. With respect to share repurchase activity at Bimini has purchased approximately 540.7 thousand shares through August 3, 2022 under the Rule 10b5-1 plan we adopted late in the Q3 of 2021.
The all-in cost of the company to repurchase these shares is approximately $996,000 or nearly 40% of the 2.5 million authorized under the plan. The prior plan was more restrictive in certain respects, and repurchases were relatively limited. The current plan provides our agent with greater flexibility, and that has accounted for the increased share repurchases to date. Given the discount the book is currently trading to relative to our book value, we view share repurchases as an attractive use of capital. That concludes my prepared remarks. Operator, and we can now turn the call over to questions.
Thank you. If you would like to ask a question, please press star followed by one on your telephone keypad. If for any reason you would like to remove that question, please press star followed by two. As a reminder to ask a question, it is star followed by one on your telephone keypad. There are no questions currently registered, so I'd like to pass the conference back over to Mr. Cauley. Please go ahead.
Thank you, operator, and thank you, everybody. To the extent somebody comes up with a question later or you listen to the replay of the call and have a question, please feel free to reach out to us. Our number here at the office is 772-231-1400. Otherwise, we look forward to speaking with you next quarter. Thank you and have a good weekend.
Thank you all for your participation. This concludes today's conference call. You may now disconnect your lines.
