Thank you, Noah. Good morning, and thank you for joining us for the Maiden Holdings First Quarter 2012 Earnings Call. Overall, we're very pleased with our performance and our results. Importantly, we continue to enjoy profitable underwriting results, strong year-on-year growth in each of our major business segments, a solid increase in invested assets, continued strong operating cash flow and significant growth in shareholders' equity and book value.
Book value per share increased 5.5% from year-end 2011, reflecting both the impact of earnings and unrealized gains in our invested asset portfolio, while our annualized return on equity and annualized return on operating equity were 10.4% and 9.9% respectively. We were also successful in completing a $100 million senior note issuance, which provides us with enhanced capital flexibility. In the context of a first quarter with significant U.S. tornado activity, continued weak fixed income yields and a competitive operating environment, we're encouraged by these results and the continued efforts of the Maiden team.
With Maiden's focus as a specialist reinsurer serving the unique noncatastrophe reinsurance needs of our regional and specialty insurer clients, we continue to enjoy relatively stable underwriting and operating performance in contrast to more catastrophe-oriented reinsurers. In the quarter, we continued to see the positive effects of the 2011 business development activity as premium writings continue to reflect the impact of both new account development and expansion of existing client relationships last year with strong written premium. We're up 31.4% versus the first quarter of 2011 with increases in all 3 of our business segments.
And when viewing the quarter, it's important to note that first quarter typically includes some level of seasonality in several of our business segments. Typically, premium levels moderate in subsequent quarters. The most significant growth was realized in the AmTrust Quota Share segment as the largest client continued its profitable expansion. It's important to note that the bulk of the 78% AmTrust growth versus first quarter 2011 was significantly the result of the addition of the European Hospital Liability business, which incepted in the second quarter of 2011 as well as their acquisition activity throughout last year.
In the Diversified Reinsurance segment, net premiums increased by 11.4%. The majority of diversified segment premium growth was in our U.S. subsidiary Maiden Re, where net premiums written grew by 20%. This increase reflects the impact of the expansion of accounts in 2011, as written premiums on both quota share and working layer accounts are recognized throughout the year. Despite a slight reduction in our 1/1/2012 renewal volume, which we mentioned in the year-end call, overall written premium reflects a productive 2011 underwriting year.
Today, we continue to actively evaluate a number of new opportunities across the diversified business platform. We believe that weather-related loss activity, capital pressures and a weak investment environment will drive increased demand for reinsurance in our core regional and specialty insurer target market. Year-on-year written premium for the balance of the diversified segment was essentially flat, reflecting a stable environment for our international business. For 2012, the International Insurance Services team is working on a number of new initiatives to increase future fee income opportunities as well as underwriting income. And lastly, the ACAC, our personal auto quota share segment, grew 19.6% from the first quarter of 2011. And notwithstanding the year-on-year written premium growth throughout Maiden, the profitability of business remains our top priority.
Underwriting results remained profitable for the quarter, but we did experience some loss ratio variability across segments. Maiden's combined ratio of 97.9% reflected strong results from our 2 largest clients. Our AmTrust Quota Share segment reflects a combined ratio of 95.5%. Compared with a year ago, that's an improvement of 1.9 percentage points.
Now looking at the components of the combined ratio, the first quarter 2012 loss ratio was 67.2% compared to 64.2% in 2011, while the expense ratio in 2012 is 28.3% versus 33.2% in 2011. These differences in both loss and expense ratio reflect a change in business mix, in particular, the impact of the Hospital Liability segment, which incepted in the second quarter of 2011.
The ACAC Quota Share produced a 96.4% combined ratio. And as we discussed last quarter, the ACAC contract has a variable commission feature. And while our fourth quarter performance exceeded the upper end of that variable commission swing rate, in the first quarter, the combined ratio moderated downward a bit, reflecting more typical first quarter seasonality and loss costs.
In the Diversified Reinsurance segment, the comparison between the first quarter of 2011 and the first quarter of 2012 is a bit complicated by the fact that in the first quarter of 2011, we reflected favorable impacts primarily associated with the GMAC International Insurance Services acquisition. In 2012, that impact is much smaller and we expect combined ratios for this segment to normalize to targeted levels.
In the quarter, the diversified segment combined ratio was also impacted by the implementation of a change in accounting rules for deferred acquisition costs, which John Marshaleck will discuss in a moment, as well as some quarterly variability in reported results to our Bermuda underwriting portfolio and our U.S. excess property business. But importantly, we don't view these results as normal levels of performance. But as we've stated in the past, we do see some variability in quarter -- or quarter combined ratios by segment.
Overall, we continue to focus on improving our overall combined ratios across Maiden and it remains a high priority. As we've commented in the past, at our current level of capital efficiency, a 1 point decrease in combined ratio can improve return on equity by more than 1.5 percentage points. We're confident that both the impact of efforts by insurers to strengthen rate levels in the U.S. and the Maiden underwriting team's continued focus on strengthening operating performance should benefit future results.
The first quarter of 2012 saw a very high incidence of tornado activity in the U.S. Despite an elevated frequency, we were very pleased to see that our risk management has been effective as our catastrophe losses remained within our normalized provision for expected losses in the quarter.
Towards the end of the first quarter, Maiden's capital position was enhanced by the issuance of $100 million 30-year 8% coupon senior note. Unlike our June 2011 debt issue and subsequent repurchase of a portion of the company's 14% coupon trust deferred securities, the economics of repurchasing more of the trust deferred securities are not currently viable. The most recent debt issuance was a great opportunity, given the market conditions and deal flow at the time. And we're very pleased to have locked in a lower cost of capital and attractive rate, given the potential uncertainty of the financial markets in the feature. The proceeds for the offering enhance our flexibility to take advantage of continued rate improvements in the insurance market or for use to eventually pay back a significant portion of the remaining balance of our trust deferred securities.
Now in that regard, I'd like to mention one housekeeping item. While we have no immediate plans to raise additional capital with 2 debt issues having been completed in the last 12 months totaling in excess of $200 million, we will shortly be replenishing our shelf registration to provide us with continued flexibility should circumstances arise in the future. Overall, we're very encouraged by the continuing development of the business. Our client retention levels remain strong and each of our business segments are well positioned to benefit from increased demand and strengthening rate levels.
I'll now turn over the call to John Marshaleck, our Chief Financial Officer, to review the first quarter financial results in a bit more detail. John?
