Thanks, Mike, and thank you, everyone, for joining us on this call. 2017 was a transformative year for Cherry Hill. We began the year by completing the transition out of Excess MSR assets and the full MSRs. And then completed both the common equity follow-on offering and a preferred stock offering. We established 2 new subservicing relationships and entered into a flow agreement for MSRs to complement our bulk acquisition strategy. At the same time, we continued to preserve book value, maintain our dividend and execute on our strategy of opportunistically deploying capital into MSRs. By the end of 2017, we had materially enhanced our ability to take advantage of investment opportunities within these strategies.
Overall, for the fourth quarter, strong performance from our RMBS portfolio along with a growing MSR portfolio helped produce core earnings per share of $0.57. We closed the quarter with a book value of $20.44, an increase of 1.9% from the prior quarter. We continue to focus on preserving book value through actively managing a portfolio of assets that we believe accomplishes that goal across multiple interest rate environments.
During the quarter, our subsidiary, Aurora, purchased over $2 billion in MSRs under our flow purchase agreement with RoundPoint, increasing the size of our MSR portfolio to nearly $12 billion in unpaid principal balance as of December 31.
We've been very pleased with our relationship with RoundPoint and it's paying significant dividends for our company.
As a reminder, the monthly $250,000 yield maintenance payments we have been receiving from Freedom Mortgage ended in the fourth quarter.
As we noted previously, while there are many variables that will affect our core EPS going forward, particularly with the pace and amount of MSR purchases, all things being equal, we expect our revenues in 2018 will be lower than in recent prior quarters due to the expiration of the payments.
Overall, our performance in 2017 and the current economic environment has reinforced our conviction that our MSR strategy is the proper course of action for Cherry Hill. We are continuing to put our capital to use in a prudent manner, using our investment experience to make MSR acquisitions at appropriate valuations, and thus, positioning us well for the months and years ahead.
At the same time, we will continue to leverage the relationships we've established to augment our sourcing, servicing and subservicing capabilities. And as always, we continue to keep a close eye on ensuring our strategy is aligned with preserving book value.
As you will hear from Julian shortly, 2018 has been eventful, to say the least. Domestic and global data have been strong. Our Fed has become increasingly comfortable with the country's macroeconomic performance, and the Trump administration remains active in its policymaking. As a result, we have witnessed a significant increase in interest rates year-to-date. All those have commented on how this has affected their book values quarter-to-date. We are happy to report that as of the February month-end, our book value has remained fairly consistent with where it stood at year-end.
The composition of our portfolio has continued to protect our investors from rising rates. And as we add more servicing-related assets, we believe the company will be able to withstand further Fed tightening over the near term. It's our expectation that our MSR portfolio will exceed $15 billion at the end of the first quarter through both bulk and flow purchases. I have high expectations for 2018 and as we look to build new relationships and capitalize on existing ones. We are excited to continue building shareholder value and growing Cherry Hill.
With that, I'll turn the call over to Julian, who will cover some more detailed highlights of our investment portfolio and its performance over the quarter.
