Thank you, Noah. Good morning, and welcome to the Maiden Holdings Fourth Quarter Earnings Call. Without question, 2011 has been one of the more challenging years on record for the reinsurance sector, in contrast for Maiden with our highly differentiated business model, which is focused on serving the non-catastrophe needs of regional and specialty insurers. I'm very pleased to report that fourth quarter and full year results continue to reflect profitable underwriting and improved cost of capital following our June debt refinancing, growth in both invested and investable assets, a year-over-year increase in book value and strong written premium growth. Importantly, we believe that Maiden is well positioned to benefit from improvements in the pricing environment in 2012 and beyond. For the most part, I'll focus my comments on the full year, while John Marshaleck, our Chief Financial Officer, will discuss the fourth quarter.
While many reinsurers have ended 2011 with a net loss in many ways, 2011 was a validation of the logic of our lower volatility non-catastrophe oriented business strategy. For 2011, we delivered an operating return on equity of 9.2% and a profitable combined ratio of 98.1%. While we aspire to a medium-term return on equity -- return on operating earnings target of 15% and a combined ratio of 96% or better, given the headwinds that were created by weakening investment yields, a challenging economic environment and record levels of catastrophes, overall, we're pleased with the results. Growth in 2011 came from all of our business segments with Diversified Reinsurance, our fastest-growing segment, increasing 44% to $798 million. As you may remember, the Diversified segment includes our U.S.-based reinsurance subsidiary, Maiden Re, and our international insurance services subsidiary. The majority of the diversified increase in revenue was in our U.S. book, and it resulted from the expansion of programs with existing clients. With the objective of maintaining significant relationships with our clients, the expansion of existing customer relationships is a very key part of our growth. In addition, we were also successful in attracting a number of new clients. A portion of the increase in the Diversified Reinsurance segment came as a result of demand for non-catastrophe capital support from new clients who were impacted by the unusually high frequency of weather losses in the U.S. during the second quarter of 2011.
And as we've previously reported, 2011 was IIS' first full year as part of Maiden. In 2011, net premiums written reflect a full year of writings and an additional $76.2 million over the 2010 written premium book by Maiden. I'm pleased to say that the IIS reinsurance business development team, which was acquired from GMAC in 2010, successfully renewed all key relationships and programs. We're well-positioned to continue our cautious international expansion through this platform, and expect our regional and specialty-based reinsurance model to further benefit European-based insurers in the future. With our specialty focus, we believe that by providing for non-catastrophe reinsurance capital needs, we can fill a valuable niche by developing customized solutions for small to midsized companies in Europe.
We continue to benefit from our relationship with AmTrust, our largest client, with net premium written of $669.3 million, up 43% in 2011. During the year, we negotiated a favorable 1% reduction in the ceding commission for 2011. Maiden also gained from AmTrust entrance into the European Hospital Liability sector, where we have a 40% quota share of what has been a well-timed opportunistic and profitable venture for AmTrust.
In addition, the growth in AmTrust written premiums also reflects their continued successful acquisition activity. Maiden's 25% reinsurance quota share with ACAC, that's the GMAC Insurance Personal Lines business, which is today a successful niche-oriented personal auto insurer, generated net premium written of $256.2 million. That's an increase of 24.5% in 2011, reflecting the full year impact of this contract, which actually incepted in March of 2010. We continue to benefit from the relative underwriting stability of this portfolio.
Again, as I mentioned, despite significant global catastrophes in 2011, we were able to achieve underwriting profitability in each quarter of 2011. The business model was tested during the second quarter when an unprecedented frequency of tornadoes and thunderstorms hit the Midwestern U.S., which caused losses for a number of our clients. Both storms impacted our second quarter result by $9.5 million. Maiden's 2011 full year combined ratio of 98.1% reflects losses from these events, as well as some variations from the target loss ratios in each of our reporting segments. We've commented in the past regarding the changing business mix in the AmTrust segment, which was addressed with the change in the ceding commission. Additionally, consistent with their own experience, we did see an increase in their overall loss ratio, which is reflected in their full year results and in the fourth quarter, but still within our performance expectations. We also believe that AmTrust's performance should benefit significantly from the strengthening pricing environment in the latter half of 2011 and on into 2012.
In the fourth quarter, our diversified combined ratio of 97.7% reflects the impact of late third quarter 2011 weather-related losses recorded in the fourth quarter from our auto reinsurance portfolio at the Maiden International Insurance Services Group, and specifically, we observe an elevated loss ratio on one of our programs. That elevated loss level reflected the impact of weather, specifically hail, over the third quarter. While certainly not a major event, it did result in roughly $2 million of increased losses, but importantly, we subsequently negotiated revisions to our contract, which will reduce future concentration exposure to weather-related activity in 2012 and beyond.
And then finally, on a full year basis, ACAC's combined ratio is performing slightly above expectation, driven by a higher-than-anticipated fourth quarter loss ratio. The increased loss ratio reflects the level of unexpected loss activity generated in specific jurisdictions. We're confident that action plans in place at ACAC will moderate future performance, and for 2012, we remain focused as a group on achieving our 96% target combined ratio across the entire Maiden underwriting portfolio. For the year, net investment income increased $3.2 million or 4.5% to $74.9 million as growth in invested assets from increased writings offset lower yields. Our conservative high-quality fixed income portfolio remains focused on government-sponsored entity bonds and high-quality investment-grade corporate bonds. Our investment portfolio continues to reflect our view that in the current investment environment, a move towards longer duration securities does not make sense.
Investable assets increased $170.4 million in 2011 to $2.5 billion. In the quarter, investment earnings were down from the prior quarter by roughly $1.6 million, which reflects the continued elevated amounts of cash and cash equivalents and reduced portfolio duration as well. As we previously reported in June of 2011, Maiden issued $107.5 million of 30-year 8.25% senior notes. The proceeds from that issuance were used to retire a like amount of 14% to a 30-year trust preferred securities that were issued in early 2009. You may remember that was a very important element of the funding of the GMAC RE acquisition. The $35 million nonrecurring cost of the debt issuance related charges lowered net income to $28.5 million, which was 59.2% below 2010, but certainly strengthened the earnings power of Maiden going forward.
Operating income was $69.6 million or $0.96 per diluted share compared to $72.7 million or $1.02 per diluted share in the previous year. Given the challenges of 2011, we believe that our operating performance demonstrates the effectiveness of Maiden's disciplined underwriting approach and stringent risk management. Our shareholders' equity increased 2.5% in 2011 to $768.6 million despite the fact that nonrecurring charges from the June debt issuance also had an impact on shareholders' equity. In light of our low volatility underwriting and conservative investment portfolio, we remain comfortable with our risk-based capital position, and believe that a more normalized level of growth in 2011 will be well-supported by our balance sheet.
I'd like to turn the call over to John Marshaleck now to review the fourth quarter result in a bit more detail.
