Donegal Group Inc. Announces First Quarter 2013 Results

MARIETTA, Pa., April 17, 2013 (GLOBE NEWSWIRE) -- Donegal Group Inc. (Nasdaq:DGICA) (Nasdaq:DGICB) today reported its financial results for the first quarter of 2013. Highlights include:

• Net income of $6.5 million for the first quarter of 2013, compared to $8.0 million for first quarter of 2012, with the decrease primarily attributable to increased large fire losses and lower realized investment gains
• 9.2% increase in net premiums written to $132.5 million, reflecting strong organic growth in commercial lines and the continued impact of premium rate increases
• 98.0% statutory combined ratio¹ for the first quarter of 2013, compared to 96.9% for the first quarter of 2012
• Operating income¹ of $5.6 million for the first quarter of 2013, compared to operating income of $6.5 million for the first quarter of 2012
• Book value per share of $15.72 at March 31, 2013, compared to $15.63 at year-end 2012

¹The "Definitions of Non-GAAP and Operating Measures" section of this release defines and reconciles data that the Company has not prepared in accordance with U.S. generally accepted accounting principles ("GAAP").

Donald H. Nikolaus, President and Chief Executive Officer of Donegal Group Inc., noted, "Donegal Group remains focused on the implementation of business strategies that will allow us to attain our long-term objectives of outperforming the property and casualty insurance industry in terms of service, profitability and growth in book value. During the first quarter of 2013, we continued to see benefits from many of the same initiatives that drove our improved performance in 2012."

Mr. Nikolaus continued, "The contribution of our initiatives to top-line growth was noteworthy, especially our continuing progress in increasing the percentage of commercial writings within our mix of business. The 18.6% growth in commercial lines net written premiums reflected premium increases averaging approximately 8.0% for renewal business, with the remainder of the increase attributable to growth in new business. Our personal lines growth of 2.7% was related almost entirely to the rate increases we have implemented over the past year, offset in part by our continuing de-emphasis of personal lines in certain jurisdictions."

"We are encouraged by the premium growth we achieved during the quarter and are optimistic about the impact the higher premiums will have on our long-term profitability.  Our combined ratio for the first quarter of 2013 was below 100% on both a GAAP and statutory basis but exceeded our targeted levels due to the occurrence of large fire losses that exceeded our quarterly average for 2012. Approximately half of the first quarter fire losses came from commercial accounts, several of which were unusual in nature. We believe the increase in commercial fire losses is an aberration, but we will monitor this development closely," Mr. Nikolaus noted.

Mr. Nikolaus continued, "Recent interactions with our independent agents and policyholders reinforce our view that substantial opportunity exists for a well-capitalized regional insurance group with a solid business strategy to grow profitably and compete effectively with national property and casualty insurance companies. We believe Donegal Group is positioned to take advantage of this opportunity. We also plan to continue to pursue appropriate acquisition opportunities that will provide additional scale to our insurance operations and complement our organic initiatives. Our primary corporate goals remain to generate increased profits, build our financial strength and enhance the value of our stockholders' investment," Mr. Nikolaus concluded.

At March 31, 2013, Donegal Group had a book value per share of $15.72, compared to $15.63 at December 31, 2012.  The Company attributes the increase in its book value per share to its positive operating results.

Insurance Operations

The Company's net premiums written increased 9.2% for the first quarter of 2013 compared to the first quarter of 2012. This increase represented the combination of 18.6% growth in commercial lines writings and 2.7% growth in personal lines writings. The $11.1 million growth in net premiums written for the first quarter of 2013 compared to the first quarter of 2012 included:

• $2.8 million, or 2.3% of total net premiums written, related to a change in the Michigan Insurance Company ("MICO") quota-share reinsurance agreement that has reduced the amount of business MICO cedes to external reinsurers. The Company acquired MICO in December 2010.
• $7.5 million in commercial lines premiums, excluding the MICO quota-share reinsurance change, that the Company attributes primarily to premium rate increases and new commercial accounts the Company's insurance subsidiaries wrote throughout their operating regions.
• $850,000 in personal lines premiums, excluding the MICO quota-share reinsurance change. The modest increase reflected the premium rate increases the Company implemented over the past four quarters, offset by our planned de-emphasis on personal lines growth in selected geographies.

Mr. Nikolaus commented, "Our ability to generate an underwriting profit in the first quarter in spite of increased large fire losses and greater severity in our workers' compensation line of business is largely attributable to the benefit of higher net premiums earned. Our workers' compensation results were impacted by the application of annual aggregate reinsurance deductibles that our insurance subsidiaries must meet before recovering reinsurance on large losses.  Results for our commercial auto line of business also reflected an increase in claim severity during the first quarter of 2013.  Based on our historical experience, we expect our commercial lines results to reflect a level of higher profitability for the remainder of 2013." 

"It is significant to note that our personal lines of business produced an underwriting profit for the first quarter of 2013. Although our personal automobile combined ratio continued to exceed our targeted range, the rate increases we implemented over the past year are helping to improve our results in our largest line of business. We are pleased that our homeowners combined ratio improved to 89.1%, reflecting the benefit of the rate increases we have implemented and the relatively favorable weather conditions we enjoyed during the quarter," Mr. Nikolaus noted.

For the first quarter of 2013, the Company's statutory loss ratio increased to 68.9%, compared to 66.4% for the first quarter of 2012. Large fire losses of $8.1 million in the first quarter of 2013, or 6.5 percentage points of the Company's loss ratio, were significantly higher than the $3.3 million, or 2.9 percentage points of the Company's loss ratio, that the Company sustained during the first quarter of 2012. For the full year 2012, large fire losses contributed 4.9 percentage points to the Company's loss ratio.

Weather-related losses of $5.6 million for the first quarter of 2013 were comparable to $5.1 million in weather-related losses for the first quarter of 2012, representing 4.5 percentage points of the Company's loss ratios in both periods. Development of reserves for losses incurred in prior accident years added 1.5 percentage points to the Company's loss ratios for the first quarter of 2013, compared to 0.4 percentage points for the first quarter of 2012. The Company considered the modest impact of reserve development in both periods to be within a reasonable range.

The Company's statutory expense ratio¹ decreased from 30.3% for the first quarter of 2012 to 28.7% for the first quarter of 2013. The decline in the expense ratio primarily reflected the impact of increased net premium writings compared to the prior-year period.

Investment Operations

Donegal Group's investment strategy is to generate an appropriate amount of after-tax income on its invested assets while minimizing credit risk through investment in high-quality securities. As a result, the Company had invested 92.6% of its consolidated investment portfolio in diversified, highly rated and marketable fixed-maturity securities at March 31, 2013.

Average fixed-maturity duration (years)	5.0		4.8

A 5.4% decrease in net investment income for the first quarter of 2013 primarily reflected the impact of the lower average investment yield within the Company's fixed-maturity securities compared to the first quarter of 2012. Net realized investment gains were $1.3 million for the first quarter of 2013, compared to $2.3 million for the first quarter of 2012. The Company had no impairments in its investment portfolio that it considered to be other than temporary during the first quarter of 2013 or 2012.

Jeffrey D. Miller, Senior Vice President and Chief Financial Officer of Donegal Group Inc., in commenting on the Company's investment operations, noted, "Throughout the insurance industry, companies are facing a challenging fixed-maturity investment environment characterized by historically low yields. We are managing both our insurance operations and investment portfolio under the assumption that prevailing interest rates will remain low for the next several years. We are continuing to stay the course in terms of targeted asset classes and investment strategy."

The Company owns 48.2% of the outstanding stock of Donegal Financial Services Corporation ("DFSC"), which owns Union Community Bank FSB. The Company accounts for its investment in DFSC using the equity method of accounting. The Company's equity in the earnings of DFSC was $1.1 million for the first quarter of 2013, compared to $1.2 million for the first quarter of 2012. Donegal Mutual Insurance Company owns the remaining 51.8% of the outstanding stock of DFSC.

Definitions of Non-GAAP and Operating Measures

The Company prepares its consolidated financial statements on the basis of GAAP. The Company's insurance subsidiaries also prepare financial statements based on statutory accounting principles state insurance regulators prescribe or permit ("SAP"). In addition to using GAAP-based performance measurements, the Company also utilizes certain non-GAAP financial measures that it believes are valuable in managing its business and for comparison to the financial results of its peers. These non-GAAP measures are operating income (loss) and statutory combined ratio.

Operating income (loss) is a non-GAAP financial measure investors in insurance companies commonly use. The Company defines operating income (loss) as net income (loss) excluding after-tax net realized investment gains or losses. Because the Company's calculation of operating income (loss) may differ from similar measures other companies use, investors should exercise caution when comparing the Company's measure of operating income (loss) to that of other companies.

The following table provides a reconciliation of net income (loss) to operating income (loss):

Realized gains (after tax)	(0.03)	(0.05)	-40.0
Operating income – Class B	$ 0.20	$ 0.24	-16.7

Statutory combined ratio is a non-GAAP standard measurement of underwriting profitability that is based upon amounts determined under SAP. The statutory combined ratio is the sum of:

• the statutory loss ratio, which is the ratio of calendar-year incurred losses and loss expenses to premiums earned;
• the statutory expense ratio, which is the ratio of expenses incurred for net commissions, premium taxes and underwriting expenses to premiums written; and
• the statutory dividend ratio, which is the ratio of dividends to holders of workers' compensation policies to premiums earned.

The statutory combined ratio does not reflect investment income, federal income taxes or other non-operating income or expense. A statutory combined ratio of less than 100% generally indicates underwriting profitability.
