Thank you, Albert and good morning, everyone. This quarter, we generated an annualized 16.9% return on average common equity and operating ROE of 15.2%. In addition, quarterly diluted book value per common share increased by more than $3 per share in the quarter. Our results benefited from a quiet catastrophe environment and a low-level of large losses as well as continued favorable prior year developments.
Valuation improvements on our available for sale investment portfolio and share repurchases executed at a discounted book value also contributed to these excellent actual results. Our strong underwriting results absorbed the impact of U.S. crop losses and hurricane Isaac during the quarter, a testament, in our opinion, to the value of diversification by geography and product in our underwriting portfolio.
We view this, coupled with the superior risk selection capabilities of our underwriters as critical to driving superior returns for our shareholders. This is especially the case, given the persistency of the low interest rate environment and the lack of sufficient compensation for taking additional risk in the investment portfolio.
Moving into the details on the income statement. Our third quarter gross premiums written were up 2.2% to $848 million. Growth emanated from our insurance segment where premiums were up $36 million attributable to a number of lines. The real growth story in the insurance segment is impacted by targeted reductions in MGA produced, cat-exposed business as we have made a tactical decisions to supply the market with cat-capacity on a more fungible basis.
The reallocation of this capacity unfortunately does not occur perfectly in tandem. Partially offsetting growth in insurance was $24 million decline in reinsurance segment premiums. Group net premiums written were down 3% in the quarter. Changes in our reinsurance purchasing effective last quarter, as well as the business mix changes contributed to a higher ceded ratio in insurance.
Our consolidated net premiums earned were up 3% this quarter. This growth was driven by insurance, including our accident and health line which has continued to increase production since we launched the product offering in 2010. This growth was partially offset by a reduction in reinsurance driven by repositioning of our catastrophe portfolio throughout this year.
Our consolidated current accident year loss ratio improved by 11.4 points during the quarter primarily due to a quieter catastrophe environment. Also, lower launch losses this quarter including reduced exposure and loss experience related to aggregate property reinsurance of regional companies in the U.S. benefited the current year. Partially offsetting these improvements were losses of $40 million related to the impact of severe drought conditions on U.S. crops which I will expand upon shortly.
In the quarter, we continued to benefit from net favorable prior year reserve development of $60 million reported in the quarter primarily from short tail lines. Our acquisition cost ratio increased a point quarter-over-quarter as business mix changes across both segments continued to earn out.
Let me address the third quarter increase in general and administrative expenses at this point. A large portion of the overall increase relates to performance related compensation costs as our annual incentive compensation accruals move in tandem with visibility on our operating results as the year unfolds. Excluding the performance related accruals, our G&A ratio was up 0.5 point. Taken together, these items produced excellent underwriting income of $155 million and a solid combined ratio of 85.3% for the quarter.
For the 9-month period, our gross premiums written were down a modest $42 million or 1%. This reduction was primarily driven by the repositioning of the catastrophe portfolio throughout the year in our reinsurance segment. Insurance gross premiums written for the year-to-date increased. Growth was associated with a more favorable rate environment and new initiatives gaining traction. Net premiums written were down slightly at 4% driven by the higher ceded ratio of insurance that I mentioned earlier. Net premiums earned were up 4% for the 9 month period driven by growth in insurance in recent quarters.
Our consolidated combined ratio of 90.8% includes 5.3 point net of reinstatements related to the first and second quarter U.S. weather events, the impact of the drought on U.S. crops and Hurricane Isaac and 7.1 points of net favorable reserve development. Excluding these items our 9-months current year accident year loss ratio improved by 2.6 points with improvements in both insurance and reinsurance.
Taking a closer look at our insurance segment. Gross premiums written were up 7% for the quarter. This growth came from our new accident and health line as well as liability and professional lines. Liability growth came from our U.S. excess and surplus lines umbrella business, professional lines growth came from newer initiatives notably our U.K. and Irish professional indemnity and our design professional and environmental initiatives.
A&H premiums were up in excess of 30% with A&H insurance in the U.S. contributing strongly to the growth. Partially offsetting these increases was a 14% reduction in property premiums. While property insurance was down for the quarter due to the property MGA reduction, it was up modestly for the year as new initiatives, such as renewable energy and the improving rate environment offset the reduction. We expect that future MGA related reductions will be similarly offset as we take advantage of the improving rate environment in our other property class.
Net premiums written were comparable quarter-over-quarter with an increase in gross premiums written largely muted by a 4 point increase in the segments ceded ratio. A large portion of this increase was driven by the higher session rate on professional lines business, after the renewal of our quota share reinsurance program last quarter. Mix changes also contributed. Most notably, in relation to growth in our liability business, where we cede a significant portion to our reinsurers in order to manage our exposure to long tail lines.
Net premiums earned in our insurance segment were up $28 million or 8% from the prior year quarter with our accident and health line contributing the majority of this growth. The current accident year loss ratio in our insurance segment improved 10.2 points in the quarter, primarily attributable to lower cat activity. The third quarter 2011 ratio included 10.1 points for Hurricane Irene and Tropical Storm Lee, while this quarter's ratio includes only 1.2 points of cat related losses related to $10 million for Hurricane Isaac and $5 million reduction in our estimate for second quarter of 2012 U.S. weather related events.
Net favorable prior year development in insurance was $32 million or 7.9 points this quarter compared to $33 million or 8.8 points in the third quarter of 2011. Changes in business mix including the growth of our accident and health business contributed to the 0.8 point increase in the acquisition cost ratio for the quarter. Our accident and health business is heavily weighted towards quota share reinsurance at this stage and therefore carries a higher commission rate than the rest of our insurance operations.
For the 9-month period, our insurance segment reported 8% and 5% growth in gross and net premiums written respectively. Excluding the impact of the catastrophe losses, the 9-month accident year loss ratio improved by 2.8 points, due mostly to a lower level of large loss activity, business mix changes and rate increases.
Turning to our reinsurance segment. Gross and net premiums written were both down 7% in the quarter. July 1 renewals dominate the third quarter and includes significant property renewals in the U.S., Australia and New Zealand. Pricing was flat to up 5% during the first renewal after a full round of increases last year. Our cat premiums were down $18 million for the quarter with approximately half of this amount due to the renewal timing of Japanese business which was extended in the third quarter of 2011 following the earthquake and tsunami, but renewed this year in the second quarter.
Premiums from our property line which includes proportional and per risk business declined during the third quarter as more cedants increased retention of business and competition increased driving less favorable economics.
Our reinsurance segment had a net reduction in premiums in the credit and bond line where growth was more than offset by reductions in premium estimates from certain cedants and competitive pressures. Our liability reinsurance premiums increased due to a variety of factors. Premium adjustments on prior year treaties accounted for $6 million or almost half of this increase in this line of business. The remainder of increase was attributable to line size increases on certain treaties and increases in expected writings by certain of our clients.
Reinsurance premiums earned were down 1% in the quarter driven by year-to-date catastrophe repositioning that I highlighted earlier. The reinsurance current accident year loss ratio for the quarter was 11.9 points lower than for the third quarter of 2011. The third quarter of 2011 ratio included 10.8 points of catastrophe losses related to Danish flooding, Hurricane Irene and the aggregate increase in first half events.
Comparatively, our results this quarter included $40 million related to the impact of severe drought conditions on U.S. crops, $10 million for Hurricane Isaac and $22 million combined reduction in loss investments, net of reinstatements for the first and second quarter U.S. weather related events. In the aggregate these amounts contributed 6.1 points the ratio.
Let me provide some additional information to put our crop losses in context. Historically we have not been a big player in crop business. We write a small volume of crop reinsurance business internationally and the 2012 portfolio includes some U.S. exposure. Our business is primarily written on an excess of loss basis. When we write on an excess of loss basis, we are being paid to take on severity risk from our clients and therefore expect lumpy results from time to time. Our $40 million provision reflects our full exposure for the U.S. drought. There will be no further impact on our financial results for this year from the U.S. drought condition.
For the accident year-to-date, our underwriting loss for this line including the impact of U.S. drought is $34 million. Since inception and through the end of this third quarter, earned premiums from our property insurance business totaled $143 million and had a technical ratio of 67%. In the last few quarters, we indicated we have a new global agriculture reinsurance initiative underway. We expect a continuous a track record of success for this line generated across a much broader global book of business. The timing certainly feels right now to bring our global reinsurance platform and expanded underwriting capability in this area to meet the demands created by prominence of agriculture in developing economies and the recent developments in the U.S. crop market.
Excluding the cat losses and the crop loss, the reinsurance segment third quarter current accident year loss ratio decreased by 7.2 points, largely due to the reduced exposure and loss experience related to the aggregate property reinsurance contracts for regional companies in the U.S. that I mentioned earlier.
Net favorable prior year reserve development in reinsurance was $29 million or 6.3 points this quarter compared to $46 million or 9.7 points in the third quarter of 2011. The reinsurance acquisition cost ratio was up a point in the quarter largely attributable to business mix changes resulting in earned premium reflecting a greater portion of quota share business. The reduction in our catastrophe business this year was the primary driver of this change. Also contributing was our decision to reduce participation in motor excess of loss business in the U.K., shifting the balance of the motor reinsurance portfolio to proportional business.
For the 9-month period, our reinsurance segment reported 9% decrease in both gross and net written premium. Earned premiums were down 2% reflecting the reposition of our catastrophe portfolio. The 83.7 combined ratio includes 5.5 points related to first and second quarter U.S. weather related events, crop losses and Hurricane Isaac and 7.2 points of net favorable reserve development. Excluding the impact of catastrophe and weather related losses I mentioned, the reinsurance segment accident year loss ratio improved by 2.3 points largely attributable to reduction of losses from regional aggregate property reinsurance contracts.
Net investment income was $104 million for the quarter, up from the second quarter's $74 million and the prior year quarter's $49 million. Net investment income improvement in the quarter was driven by the strong return from other investments of $34 million compared to net losses of $2 million and $30 million in the second quarter of this year and the third quarter of 2011, respectively.
Hedge fund performance was the major driver of the increase in net investment income from other investments during the quarter. Year-to-date net investment income contribution from our other investment portfolio was $72 million for a total return of 9.3%. Income from our fixed maturities, cash and short-term investments was $73 million this quarter down $5 million from the second quarter of this year and $10 million from the third quarter of 2011 due to lower reinvestment yields.
In aggregate, the total return on our cash and investment portfolio for the quarter was 2.1%, inclusive of foreign exchange impact. During the quarter, net unrealized gains on our fixed maturities and equity holdings increased by $149 million to $395 million. Additionally net gains realized in the quarter totaled $51 million due principally to changes executed in the fixed maturity portfolio. Yield spreads continue to contract for investment-grade and particularly high yield fixed maturity issued during the quarter while the U.S. Treasury intermediate maturity section of the yield curve was relatively unchanged.
In general, the longer the maturity, the more significant the price improvement for these spread sectors. While the decline in yield and spreads positively impacted the unrealized gain position in our fixed maturity portfolio during the quarter, the result will likely be lower net investment income going forward as the fixed maturity book yield of 2.7% converges with the market yield of 1.4%, as most global central banks maintain policies aimed at keeping rates low for a protracted period of time.
The net of all these items and the G&A variants I discussed earlier was a strong quarterly operating income of $201 million or $1.63 per diluted share and net income available to common shareholders of $223 million or $1.82 per diluted share. This equates to an annualized operating ROE of 15.2% and a net income ROE of 16.9%.
Moving to the balance sheet. The total assets increased 1% in the quarter driven by growth in our investment portfolio arising from investment of operating cash flows and valuation improvements. Cash and invested assets totaled $14.2 billion at quarter end versus $13.9 billion at the end of the second quarter. Our fixed maturity portfolio whose average credit quality remains at AA minus continues to be our largest asset class comprising 83% of cash and invested assets.
The strategy for our fixed maturity portfolio is to continue emphasizing spread sectors, the largest being corporates and U.S. agency mortgage backed securities. With a non-U.S., governments, we continue to increase our allocations to emerging market local currency debt while reducing European sovereign debt.
We reduced Eurozone sovereign and corporate debt exposure in the quarter after a strong rally in these sectors. Our Eurozone sovereign exposures are now primarily limited to Germany, the Netherlands and Australia. Further information on our current Eurozone holdings can be found in our investor's supplement.
In summary, the investment portfolio performed in line with expectations during the quarter and year-to-date but remains challenged to maintain current levels of net investment income and in this historic low yield environment. Our total capital at September 30, 2012 was $6.9 billion up 6% from $6.4 billion at year-end 2011. Common shareholders equity stood at $5.4 billion at quarter end, up from year-end 2011 due to net income and valuation improvement on our available-for-sale investment portfolio exceeding our share repurchase activity and dividends.
We repurchased 5.2 million shares at a discounted book value in the third quarter for an aggregate cost of $179 million. Our diluted book value reached the third consecutive record high this quarter, reaching $43.57 per diluted share. With our strong capital base, a high quality and liquid investment portfolio, sound loss reserves and a global diversified franchise in both insurance and reinsurance, it is our belief that we will continue to benefit from available market opportunities and accrete value to our shareholders.
With that I will turn the call back over to Albert.
