Cynthia Y. Valko, Chief Executive Officer, commented: “Over the nine month period ending September 30, our operating margins continued to improve, enhancing profitability and our return on capital. From a top line perspective, excluding commercial auto (where we determined to reduce exposure) our premium revenue continued to grow, increasing more than 5% compared to the comparable 2013 period. We are experiencing healthy growth in small business, programs and casualty reinsurance. However, our large property insurance and catastrophe reinsurance premiums are flat with last year as a result of increased competition, particularly from new entrants to the insurance marketplace, including pension plans, hedge funds, and other non-insurance companies seeking insurance underwriting income to replace yields no longer available in the bond market. The absence of credible bond market yields on high quality, short and mid-term duration fixed income assets, which constitute roughly 85% or more of Global’s investment holdings, significantly constrains Global’s investment and net income. In regard to the balance sheet, in late June, Global trimmed its equity portfolio by selling $150 million of its $275 million equity portfolio (approximately, 55%), realizing a net capital gain of $43 million. Global utilized part of the $150 million of sale proceeds to pay down a portion of the outstanding balance of its credit facility with J.P. Morgan (NYSE: JPM). As a result of reducing its equity portfolio and applying the proceeds to debt reduction, Global’s cash and invested assets contracted by $50 million (approximately) while its funded debt declined by about $40 million between December 31 and September 30, 2014.

Cynthia Valko continued: “Finally, I am also delighted to report that on October 16, Global agreed to acquire American Reliable Insurance Company (“American Reliable”), a specialty provider of personal lines and agricultural (equine, farm, & ranch) insurance, from Assurant, Inc. (NYSE: AIZ). In this roughly $400 million enterprise value transaction, Global will pay Assurant approximately $114 million in cash at closing (which could be increased to approximately $120 million to account for net earnings between June 30, 2014 and the closing) and will assume approximately $280 million of insurance related obligations. Global will utilize its internal resources and capital base to finance the transaction. The American Reliable acquisition, which is anticipated to close by year end, is expected to both double Global’s insurance premium revenue and be accretive to earnings in 2015.”

Global Indemnity plc’s Combined Ratio for the Three and Nine Months Ended September 30, 2014 and 2013

The combined ratio is a key measure of insurance profitability. The components comprising the combined ratio are as follows:

For the three months ended September 30th, the calendar year loss ratio decreased by 1.2 points to 53.9 in 2014 from 55.1 in 2013.

For the three months ended September 30, 2014, the current accident year loss ratio improved to 53.7 compared to 57.6 for the same period in 2013. Excluding catastrophes, the current accident year loss ratio improved by 2.8 points, from 48.1 in 2013 to 45.3 in 2014.

Calendar year results for the three months ended September 30, 2014 include a 0.2 point increase in the loss ratio related to prior accident years, which was primarily driven by an increase in marine severity within the Reinsurance Operations, partially offset by less than anticipated catastrophe losses.

For the three months ended September 30^th, the expense ratio decreased from 43.5 in 2013 to 40.4 in 2014.

The decrease is primarily due to the recognition of a $1.7 million premium deficiency charge in 2013.

For the nine months ended September 30^th, the calendar year loss ratio improved by 0.7 points to 56.3 in 2014 from 57.0 in 2013.

For the nine months ended September 30, 2014, the current accident year loss ratio improved by .5 points to 59.3 compared to 59.8 for the same period in 2013. Excluding catastrophes, the current accident year loss ratio improved by 2.4 points, from 49.1 in 2013 to 46.7 in 2014.

Calendar year results for the nine months ended September 30, 2014 include a 3.0 point reduction in the loss ratio related to prior accident years, which was primarily driven by lower than excepted severity in the U.S. Insurance Operations professional lines.

For the nine months ended September 30^th, the expense ratio decreased from 43.0 in 2013 to 40.2 in 2014.

The improvement in the expense ratio is primarily due to the growth in earned premium volume in 2014 as well as the impact of the premium deficiency charge of $1.7 million recognized in 2013.
