Exhibit 99.1 Harleysville Group Reports Fourth Quarter and Year-End 2003 Results HARLEYSVILLE, Pa., Feb. 17 /PRNewswire-FirstCall/ -- Harleysville Group Inc. (Nasdaq: HGIC) today reported a diluted net loss of $0.66 per share in the fourth quarter of 2003, reflecting the previously announced loss reserve increases in several business lines for prior accident years. The company had diluted net income of $0.57 per share in the fourth quarter of 2002. There were essentially no realized investment gains or losses in the fourth quarter of 2003, compared to $0.04 per share of realized gains in the fourth quarter of 2002. For the 12 months, the company reported a diluted net loss per share of $1.59, compared to diluted net income per share of $1.53 in 2002. For the full year, 2003 results included realized investment losses of $0.02 per share, compared to $0.39 per share of realized losses in 2002. The company reported a diluted operating loss of $0.66 per share for the fourth quarter ended December 31, 2003, compared to diluted operating income of $0.53 per share in the same period of 2002. For the 12 months ended December 31, 2003, the diluted operating loss was $1.57 per share, compared to diluted operating income of $1.92 per share in the same period of 2002. Operating income is a non-GAAP financial measure defined by the company as net income excluding after-tax realized gains and losses on investments. "Our 2003 results were totally unacceptable," commented Michael L. Browne, Harleysville Group's chief executive officer. "We will return Harleysville not only to profitability, but also to superior levels of profitability. To do this, we have strengthened our management in key areas, including claims, and conducted thorough claims and actuarial reviews, using internal and external resources, in order to address the issues that led to our additions to loss reserves in 2003. With these changes in place, we can now focus on growing our business and our profits." The company's fourth quarter and 12-month results were reduced by the previously announced addition of $42 million pretax, or $0.92 per share after tax, to the company's loss and loss adjustment reserves for prior accident years, primarily in its workers compensation ($11.8 million), commercial automobile ($9.5 million), commercial multi-peril ($19.3 million) and personal automobile ($3.8 million) lines of business. Harleysville Group's end-of-the- quarter reserve analysis showed higher-than-expected development in the casualty lines of business in accident years prior to 2003, which caused the company to make the reserve adjustment. Of the reserve development, about two-thirds relates to the 1999 to 2001 accident years. Harleysville Group's 12-month earnings were reduced by $119 million pretax, or $2.58 per share after tax, due to reserve development. In light of the higher-than-expected development in prior accident years, the company raised its loss estimates for the 2003 accident year, which also impacted the company's fourth quarter and 12-month results. The full-year results also reflect claims costs of $8.8 million pretax, or $0.19 per share after tax, from Hurricane Isabel in September. In 2003, Harleysville Group's property catastrophe losses were $19.7 million pretax, or $0.43 per share after tax. That compares to property catastrophe losses of $4.4 million pretax, or $0.10 per share after tax, for 2002. Harleysville Group's overall statutory combined ratio* was 134.6 percent in the fourth quarter of 2003, compared to 102.1 percent in the fourth quarter of 2002. For the 12 months, the statutory combined ratio was 123.2 percent in 2003, versus 101.9 percent in 2002. Reserve development added 20.0 points and 14.5 points to the 2003 fourth quarter and 12-month statutory combined ratios, respectively. In addition, property catastrophe losses added 2.4 points and 0.6 points to the 2003 and 2002 statutory combined ratios, respectively. A $13 million cash contribution to the pension plan added 6.5 points and 1.6 points to the 2003 fourth quarter and 12-month combined ratios, respectively, but did not affect GAAP pension expense. Fourth quarter net written premiums rose 3 percent to $197.6 million in 2003, while net written premiums through 12 months increased by 6 percent to $843.5 million in 2003. Pretax investment income increased 2 percent in the fourth quarter to $21.9 million, but was virtually unchanged for the year at $86.6 million. After-tax investment income rose 3 percent in the fourth quarter to $17.0 million and 2 percent for the year to $66.8 million. Operating cash flow for the 12 months was $134.6 million, or $21.4 million higher than the prior year's 12 months. Commercial lines Net written premiums climbed 10 percent in both the fourth quarter and the year to $155.0 million and $657.5 million, respectively. The increase in written premiums is primarily due to higher pricing. The commercial lines statutory combined ratio was 137.1 percent in the fourth quarter of 2003, versus 98.7 percent in the fourth quarter of 2002. For the 12 months, the statutory combined ratio was 123.6 percent in 2003, compared to 99.5 percent in 2002. In 2003, the fourth quarter reserve development added 23.3 points to the quarter's commercial lines statutory combined ratio, while reserve development added 17.2 points to the 12-month commercial lines statutory combined ratio. Personal lines Harleysville Group's personal lines statutory combined ratio was 125.9 percent in the fourth quarter of 2003, versus 112.2 percent during the fourth quarter of 2002. For the 12 months, the statutory combined ratio was 121.8 percent in 2003, compared to 108.1 percent in 2002. In 2003, reserve development added 8.2 points to the fourth quarter personal lines statutory combined ratio and 5.5 points to the 12-month personal lines statutory combined ratio. The higher catastrophe losses also contributed to the higher statutory combined ratio. Net written premiums declined 15 percent to $42.6 million in the fourth quarter of 2003 and were down 8 percent to $186.0 million during the year. Outlook "We are committed to improved profitability in commercial lines and personal lines," Browne explained. "In commercial lines, we will continue with our strategy aimed at the core business controlled by our independent agency partners. In personal lines, the business plan we've put in place in the last two quarters is realistic and achievable, and it has been welcomed enthusiastically by our agents. "Our financial condition is solid. We have a strong balance sheet, characterized by significantly strengthened reserves, a modest 17 percent debt-to-capital ratio, a high-quality investment portfolio and a premium-to- surplus ratio of 1.8 to 1. Additionally, operating cash flow is at a historical high," Browne continued. "Our relationships with our agents are strong. As we move past the issues of 2003, we know we will improve our results in 2004 and beyond. We are going to focus intensely on four cornerstones -- underwriting, claims handling, service to agents and policyholders, and productivity. Bottom line, our future success will be driven by consistent execution of the fundamentals." Webcast The company will host a live Webcast today, Tuesday, February 17, 2004, at 9:00 a.m. (ET) to discuss its fourth quarter results. The Webcast will be available from the Investors section of the company's Web site (www.harleysvillegroup.com) and will be archived on the Web site until February 17, 2005. GAAP and non-GAAP financial measures The company uses a non-GAAP financial measure called "operating income" that management believes is useful to investors because it illustrates the performance of normal, ongoing operations, which is important in understanding and evaluating the company's financial condition and results of operations. While this measure is utilized by investors to evaluate performance, it is not a substitute for the U.S. GAAP financial measure of net income. Therefore, a reconciliation of this non-GAAP financial measure to the U.S. GAAP financial measure of net income is provided following the Consolidated Statements of Income contained in this release. Management also uses operating income for goal setting, determining employee and senior management compensation, and evaluating performance. Corporate profile Recognized as "Good people to know" in the markets it serves, Harleysville Insurance is a premier provider of insurance products and services for small businesses and individuals, and ranks among the top 60 U.S. property/casualty insurance groups based on net written premiums. Harleysville Group Inc. (Nasdaq: HGIC) is a publicly traded holding company for nine regional property/casualty insurance companies. Harleysville Insurance, which distributes its products exclusively through independent insurance agencies, currently operates in 32 Eastern and Midwestern states. Further information can be found on the company's Web site (www.harleysvillegroup.com). * "Statutory combined ratio" is a non-GAAP measure of underwriting profitability and is based on numbers determined under statutory accounting practices as filed with state insurance regulators. It is the sum of the ratio of losses to premiums earned plus the ratio of underwriting expenses to premiums written. A ratio of less than 100 percent indicates underwriting profitability. Certain of the statements contained herein (other than statements of historical facts) are forward-looking statements. Such forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and include estimates and assumptions related to economic, competitive and legislative developments. These forward- looking statements are subject to change and uncertainty that are, in many instances, beyond the company's control and have been made based upon management's expectations and beliefs concerning future developments and their potential effect on Harleysville Group Inc. There can be no assurance that future developments will be in accordance with management's expectations so that the effect of future developments on Harleysville Group will be those anticipated by management. Actual financial results including premium growth and underwriting results could differ materially from those anticipated by Harleysville Group depending on the outcome of certain factors, which may include changes in property and casualty loss trends and reserves; catastrophe losses; the insurance product pricing environment; changes in applicable law; government regulation and changes therein that may impede the ability to charge adequate rates; changes in accounting principles; performance of the financial markets; fluctuations in interest rates; availability and price of reinsurance; and the status of the labor markets in which the company operates.
