Business.

General

Harleysville Group Inc. (the Company) is an insurance holding company headquartered in Pennsylvania which, through its subsidiaries, engages in the property and casualty insurance business on a regional basis. As used herein, “Harleysville Group” refers to Harleysville Group Inc. and its subsidiaries.

The Company is a Delaware corporation formed by Harleysville Mutual Insurance Company (the Mutual Company) in 1979 as a wholly owned subsidiary. In May 1986, the Company completed an initial public offering of its common stock, reducing the percentage of outstanding shares owned by the Mutual Company to approximately 70%. In April 1992, the Mutual Company completed a secondary public offering of a portion of the Company’s common stock then owned by it, further reducing the percentage of outstanding shares owned by the Mutual Company. At December 31, 2007, the Mutual Company owned approximately 53% of the Company’s outstanding shares.

Harleysville Group and the Mutual Company operate together to pursue a strategy of underwriting a broad array of personal and commercial coverages. These insurance coverages are marketed primarily in the eastern and midwestern United States through approximately 1,500 insurance agencies. Regional offices are maintained in Georgia, Illinois, Indiana, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Carolina, Pennsylvania, Tennessee, and Virginia. The Company’s property and casualty insurance subsidiaries are: Harleysville-Atlantic Insurance Company (Atlantic), Harleysville Insurance Company (HIC), Harleysville Insurance Company of New Jersey (HNJ), Harleysville Insurance Company of New York (HIC New York), Harleysville Insurance Company of Ohio (HIC Ohio), Harleysville Lake States Insurance Company (Lake States), Harleysville Preferred Insurance Company (Preferred), and Harleysville Worcester Insuran ce Company (Worcester). Mid-America Insurance Company (Mid-America), a former subsidiary, was merged into Worcester in 2007.

The Company operates regionally. Management believes that the Company’s regional organization permits each regional operation to benefit from economies of scale provided by centralized support while encouraging local marketing autonomy and managerial entrepreneurship. Services which directly involve the insured or the agent (i.e., underwriting, claims and marketing) generally are performed regionally in accordance with Company-wide standards to promote high quality service, while actuarial, investment, legal, data processing and similar services are performed centrally. The Company’s network of regional insurance companies has expanded significantly in the last twenty-four years. In 1983, the Company acquired Worcester, a property and casualty insurer which has conducted business in New England since 1823. In 1984, HNJ was formed by the Company and began underwriting property and casualty insurance in New Jersey. In 19 87, the Company acquired Atlantic, a property and casualty insurer which has conducted business in the southeastern United States since 1905. In 1991, the Company acquired Mid-America, which conducted business in Connecticut, and HIC New York, which primarily conducts business in upstate New York. In 1993, the Company acquired Lake States, which primarily conducts business in Michigan. In 1994, the Company formed HIC Ohio which began underwriting property and casualty insurance in Ohio. In 1997, the Company acquired HIC, which primarily conducts business in Minnesota and neighboring states.

The Company’s property and casualty subsidiaries participate in an intercompany pooling arrangement whereby these subsidiaries cede to the Mutual Company all of their net premiums written and assume from the Mutual Company a portion of the pooled business, which includes substantially all of the Mutual Company’s property and casualty insurance business. See “Business - Pooling Arrangement.”

Business Segments

Harleysville Group has three segments which consist of the personal lines of insurance, the commercial lines of insurance and the investment function. Financial information about these segments is set forth in Note 12 of the Notes to Consolidated Financial Statements.

Narrative Description of Business

Property and Casualty Underwriting

Harleysville Group and the Mutual Company together underwrite a broad line of personal and commercial property and casualty coverages, including automobile, homeowners, commercial multi-peril and workers compensation. The Mutual Company and the Company’s insurance subsidiaries participate in an intercompany pooling arrangement under which such subsidiaries and the Mutual Company combine their property and casualty business.

Harleysville Group and the Mutual Company have a pooled rating of “A-” (excellent) which was affirmed by A.M. Best Company, Inc. (Best’s) in January 2008. Best’s ratings are based upon factors relevant to policyholders and are not directed toward the protection of investors. Management believes that the Best’s rating is an important factor in marketing Harleysville Group’s products to its agents and customers, and that the current rating is satisfactory in that regard.

The following table sets forth ratios for the Company’s property and casualty subsidiaries, prepared in accordance with U.S. generally accepted accounting principles (GAAP) and with statutory accounting practices (SAP) prescribed or permitted by state insurance authorities. The statutory combined ratio is a standard measure of underwriting profitability. This ratio is the sum of (i) the ratio of incurred losses and loss settlement expenses to net earned premium (loss ratio); (ii) the ratio of expenses incurred for commissions, premium taxes, administrative and other underwriting expenses to net written premium (expense ratio); and (iii) the ratio of dividends to policyholders to net earned premium (dividend ratio). The GAAP combined ratio is calculated in the same manner except that it is based on GAAP amounts and the denominator for each component is net earned premium. When the combined ratio is under 100%, underwriting r esults are generally considered profitable. Conversely, when the combined ratio is over 100%, underwriting results are generally considered unprofitable. The combined ratio does not reflect investment income, federal income taxes or other non-operating income or expense. Harleysville Group’s operating income is a function of both underwriting results and investment income.

Pooling Arrangement

The Company’s property and casualty subsidiaries participate in an intercompany pooling arrangement with the Mutual Company. The underwriting pool is intended to produce a more uniform and stable underwriting result from year to year for all companies in the pool than they would experience individually and to reduce the risk of loss of any of the pool participants by spreading the risk among all the participants. Each company participating in the pool has at its disposal the capacity of the entire pool, rather than being limited to policy exposures of a size commensurate with its own capital and surplus. The additional capacity exists because such policy exposures are spread among all the pool participants which each have their own capital and surplus. Regulation is applied to the individual companies rather than to the pool.

Pursuant to the terms of the pooling agreement with the Mutual Company, each of the Company’s subsidiary participants cedes premiums, losses and underwriting expenses on all of its business to the Mutual Company which, in turn, retrocedes to such subsidiaries a specified portion of premiums, losses and underwriting expenses of the Mutual Company and such subsidiaries. Under the terms of the intercompany pooling agreement which became effective January 1, 1986, Preferred and HNJ ceded to the Mutual Company all of their insurance business written on or after January 1, 1986. All of the Mutual Company’s property and casualty insurance business written or in force on or after January 1, 1986, was also included in the pooled business. The pooling agreement provides, however, that Harleysville Group is not liable for any losses incurred by the Mutual Company, Preferred and HNJ prior to January 1, 1986. Th e

pooling agreement does not legally discharge Harleysville Group from its primary liability for the full amount of the policies ceded. However, it makes the Mutual Company liable to Harleysville Group to the extent of the business ceded.

The following table sets forth a chronology of the changes that have occurred in the pooling agreement since it became effective on January 1, 1986.

Chronology of Changes in Pooling Agreement


Date	Harleysville Group Percentage	Mutual Company/Pennland Percentage	Event
January 1, 1986	30%	70%	Current pooling agreement began with Preferred and HNJ as participants with the Mutual Company.
July 1, 1987	35%	65%	Atlantic acquired and included in the pool.
January 1, 1989	50%	50%	Worcester included in the pool.
January 1, 1991	60%	40%	HIC New York and Mid-America acquired and included in the pool and the Mutual Company formed Pennland (not a pool participant) to write Pennsylvania personal automobile business.
January 1, 1996	65%	35%	Pennland included in the pool.
January 1, 1997	70%	30%	Lake States included in the pool.
January 1, 1998	72%	28%	HIC included in the pool.
January 1, 2008	80%	20%	Amendment to the pooling agreement.

When pool participation percentages increased as described above, cash and investments equal to the net increase in liabilities assumed less a ceding commission related to the net increase in the liability for unearned premiums, was transferred from the Mutual Company to Harleysville Group.

All premiums, losses, loss settlement expenses and other underwriting expenses are prorated among the parties to the pooling arrangement on the basis of their participation in the pool. The method of establishing reserves is set forth under “Business - Reserves.” The pooling agreement may be amended or terminated by agreement of the parties. Termination may occur only at the end of a calendar year. The Boards of Directors of the Company and the Mutual Company maintain a coordinating committee which reviews and evaluates, and when changes are warranted, approves the pooling arrangements between the Company and the Mutual Company. See “Business-Relationship with the Mutual Company.” In evaluating pool participation changes, the coordinating committee considers current and proposed acquisitions, the relative capital positions and revenue contributions of the pool participants, and growth prospects and ability to access capital markets to support that growth. Harleysville Group does not intend to terminate its participation in the pooling agreement.

The following table sets forth the net premiums written and combined ratios by line of insurance for the total pooled business after elimination of management fees, prepared in accordance with statutory accounting practices prescribed or permitted by state insurance authorities, for the periods indicated.

See the definition of combined ratio in “Business-Property and Casualty Underwriting.”

The combined ratio for the total pooled business differs from Harleysville Group’s combined ratio primarily because of the effect of the inclusion of incurred losses occurring prior to 1986 retained by the Mutual Company and, for 2005, the effect of the aggregate catastrophe reinsurance agreement with the Mutual Company. See Note 2(a) of the Notes to Consolidated Financial Statements and Business–Reinsurance.

Reserves.Loss reserves are estimates at a given point in time of what the insurer expects to pay to claimants for claims occurring on or before such point in time, including claims which have been incurred but not yet reported to the insurer. These are estimates, and it can be expected that the ultimate liability will exceed or be less than such estimates. During the loss settlement period, additional facts regarding individual claims may become known, and consequently it often becomes necessary to refine and adjust the estimates of liability.

Harleysville Group maintains reserves for estimates of the ultimate unpaid cost of all losses incurred, including losses for claims which have been incurred but have not yet been reported to Harleysville Group. Loss settlement expense reserves are intended to cover the ultimate costs of settling all claims, including investigation and litigation costs relating to such claims. The amount of loss reserves for reported claims is based primarily upon a case-by-case evaluation of the type of risk involved and knowledge of the circumstances surrounding each claim and the insurance policy provisions relating to the type of loss. The amounts of loss reserves for incurred but unreported claims and loss settlement expense reserves are determined utilizing historical information by line of insurance as adjusted to

current conditions. Inflation is implicitly provided for in the reserving function through analysis of costs, trends and reviews of historical reserving results. Estimates of the liabilities are reviewed and updated on a regular basis using the most recent information on reported claims and a variety of actuarial techniques. With the exception of reserves relating to some workers compensation long-term disability cases, loss reserves are not discounted.

The following table sets forth a reconciliation of beginning and ending net reserves for unpaid losses and loss settlement expenses for the years indicated for the total pooled business on a statutory basis.

Reserves for losses and loss settlement expenses, end of the year	$	1,967,094		$	1,893,753		$	1,761,198

The following table sets forth the development of net reserves for unpaid losses and loss settlement expenses from 1997 through 2007 for the pooled business of the Mutual Company and Harleysville Group on a statutory basis. “Reserve for losses and loss settlement expenses” sets forth the estimated liability for unpaid losses and loss settlement expenses recorded at the balance sheet date for each of the indicated years. This liability represents the estimated amount of losses and loss settlement expenses for claims arising in the current and all prior years that are unpaid at the balance sheet date, including losses incurred but not reported.

The “Reserves reestimated” portion of the table shows the reestimated amount of the previously recorded liability based on experience of each succeeding year. The estimate is increased or decreased as payments are made and more information becomes known about the severity of remaining unpaid claims. For example, the 1997 liability has developed a redundancy after ten years, in that reestimated losses and loss settlement expenses are expected to be lower than the initial estimated liability established in 1997 of $1,125 million by $18.5 million, or 1.6%.

The “Cumulative amount of reserves paid” portion of the table shows the cumulative losses and loss settlement expense payments made in succeeding years for losses incurred prior to the balance sheet date. For example, the 1997 column indicates that as of December 31, 2007, payments of $940.4 million of the currently reestimated ultimate liability for losses and loss settlement expenses had been made.

The “Redundancy (deficiency)” portion of the table shows the cumulative redundancy or deficiency at December 31, 2007 of the reserve estimate shown on the top line of the corresponding column. A redundancy in reserves means that reserves established in prior years exceeded actual losses and loss settlement expenses or were reevaluated at less than the original reserved amount. A deficiency in reserves means that the reserves established in prior years were less than actual losses and loss settlement expenses or were reevaluated at more than the originally reserved amounts.

The following table includes all 2007 pool participants as if they had participated in the pooling arrangement in all years indicated except for acquired pool participant companies, which are included from their date of acquisition. Under the terms of the pooling arrangement, Harleysville Group is not responsible for losses on the pooled business of the Mutual Company, Preferred and HNJ occurring prior to January 1, 1986.

Excludes business not included in pooling arrangement with Harleysville Group.

Harleysville Group’s reserves primarily are derived from those established for the total pooled business. The terms of the pooling agreement provide that Harleysville Group is not liable for any losses incurred by the Mutual Company, Preferred and HNJ prior to January 1, 1986. The GAAP loss reserve experience of Harleysville Group, as reflected in its financial statements, is shown in the following table which sets forth a reconciliation of beginning and ending net reserves for unpaid losses and loss settlement expenses for the years indicated for the business of Harleysville Group only.

See page 9 for reconciliation of net reserves to gross reserves.

Harleysville Group recognized net favorable development in the provision for insured events of prior years of $22.0 million in 2007, primarily due to lower-than-expected claims severity broadly experienced across all casualty lines in accident years 2003 through 2006, partially offset by adverse development in the 2002 and prior accident years. The favorable development consisted of $12.5 million in commercial lines and $9.5 million in personal lines.

Harleysville Group recognized net favorable development in the provision for insured events of prior years of $18.1 million in 2006, primarily due to lower-than-expected claims severity in accident years 2002 through 2005 for most commercial and personal lines of business, partially offset by greater-than-expected claims severity in the 2001 and prior accident years. The favorable development consisted of $8.1 million in commercial lines and $10.0 million in personal lines.

Harleysville Group recognized net favorable development in the provision for insured events of prior years of $17.5 million in 2005, primarily due to lower-than-expected claims severity in accident years 2004 and 2003, partially offset by greater-than-expected claims severity in commercial lines in 2002 and prior accident years. The favorable development consisted of $3.9 million in commercial lines and $13.6 million in personal lines.

The following table sets forth the development of net reserves for unpaid losses and loss settlement expenses for Harleysville Group. The effect of changes to the pooling agreement participation is reflected in this table. For example, the January 1, 1998 increase in Harleysville Group’s pooling participation from 70% to 72% is reflected in the first line of the 1998 column. Amounts of assets equal to increases in net liabilities were transferred to Harleysville Group from the Mutual Company in conjunction with each respective pooling change. The amount of the assets transferred has been netted against and has reduced the cumulative amounts paid for years prior to the pooling changes.

For example, the 1997 column of the “Cumulative amount of reserves paid” portion of the table reflects the assets transferred in conjunction with the 1998 increase in the pooling percentage from 70% to 72% as a decrease netted in the “one year later” line. The cumulative amounts paid are reflected in this manner to maintain comparability. This is because when Harleysville Group pays claims subsequent to the date of a pool participation increase, the amounts paid are greater however, the prior year’s reserve amounts are reflective of a lower pool participation percentage. By reflecting pooling participation increases in this manner, loss development is not obscured. Loss development reflects Harleysville Group’s share of the total pooled business loss development since January 1, 1986 when Harleysville Group began participation, plus loss development of any subsidiary not participating in the pooling agr eement.

Loss development information for the total pooled business is presented on pages 6 to 8 to provide greater analysis of underlying claims development.

Note:

The amount of cash and investments received equal to the increase in liabilities for unpaid losses and loss settlement expenses was $28,318,000 and $12,392,000 for the changes in pool participation in 1997 and 1998, respectively.

Reinsurance.Harleysville Group follows the customary industry practice of reinsuring a portion of its exposures and paying to the reinsurers a portion of the premiums received. Insurance is ceded principally to reduce the net liability on individual risks and to protect against catastrophic losses. Reinsurance does not legally discharge an insurer from its primary liability for the full amount of the policies, although it does make the assuming reinsurer liable to the insurer to the extent of the reinsurance ceded. Therefore, a ceding company is subject to credit risk with respect to its reinsurers. Harleysville Group has not entered into any finite reinsurance agreements.

The reinsurance described below is maintained for the Company’s subsidiaries and the Mutual Company and its wholly owned subsidiaries. Reinsurance premiums and recoveries are allocated to participants in the pooling agreement according to pooling percentages.

Reinsurance for property and auto physical damage losses is currently maintained under a per risk excess of loss treaty affording recovery to $13.0 million above a retention of $2.0 million. Harleysville Group’s 2007 pooling share of such recovery would be $9.4 million above a retention of $1.4 million. In addition, the Company’s subsidiaries and the Mutual Company and its wholly owned subsidiaries are reinsured under a catastrophe reinsurance treaty effective for one year from July 1, 2007 which provides coverage ranging from 75% to 85% of up to $250.0 million in excess of a retention of $50.0 million for any given catastrophe. Harleysville Group’s 2007 pooling share of this coverage would range from 75% to 85% of up to $180.0 million in excess of a retention of $36.0 million for any given catastrophe. Accordingly, pursuant to the terms of the treaty, the maximum recov ery would be $195.0 million for any catastrophe involving an insured loss equal to or greater than $300.0 million. Harleysville Group’s pooling share of this maximum recovery would be $140.4 million for any catastrophe involving an insured loss of $216.0 million or greater. The treaty includes reinstatement provisions providing for coverage for a second catastrophe and requiring payment of an additional premium in the event of a first catastrophe occurring. Most terrorism losses would not be covered by the treaty. Harleysville Group has not purchased funded catastrophe covers.

Casualty reinsurance (including liability and workers compensation subject to per-life maximums) is currently maintained under an excess of loss treaty affording recovery to $37.0 million above a retention of $3.0 million for each loss occurrence. Harleysville Group’s 2007 pooling share of a recovery would be up to $26.6 million above a retention of $2.2 million. In addition, there is reinsurance to protect Harleysville Group from large workers compensation losses on a per-life basis above a retention of $2.0 million. Harleysville Group’s pooling share of this retention would be $1.4 million. For umbrella liability coverages, reinsurance protection up to 75% of the first $4.0 million over a retention of $1.0 million and 100% of the next $5.0 million in excess of $5.0 million is provided. Harleysville Group’s 2007 pooling share would provide for a maximum recovery o f $5.8 million over a retention of $0.7 million. The casualty reinsurance programs provide coverage for a terrorist event with no reinstatement provision.

The terms and charges for reinsurance coverage are typically negotiated annually. The reinsurance market is subject to conditions which are similar to those in the direct property and casualty insurance market, and there can be no assurance that reinsurance will remain available to Harleysville Group to the same extent and at the same cost currently maintained.

Harleysville Group considers numerous factors in choosing reinsurers, the most important of which are the financial stability and credit worthiness of the reinsurer. Harleysville Group has not experienced any material uncollectible reinsurance recoverables.

The Company’s subsidiaries and the Mutual Company are servicing carriers in the “Write-Your-Own” (WYO) program of the United States government’s National Flood Insurance Program (NFIP). The WYO program is a cooperative undertaking of the insurance industry and the Federal Emergency Management Agency. As servicing carriers, Harleysville Group and the Mutual Company bear no risk of loss on flood insurance policies. All of the premiums collected on flood insurance policies are ceded to the federal government and, in exchange a servicing fee is received from which agency commission, claim handling fees and other related expenses are paid.

As a writer of personal and commercial automobile policies in the state of Michigan, in compliance with applicable state regulations, Harleysville Group cedes premiums and claims for medical benefits and work loss, above a specified retention amount, to the Michigan Catastrophic Claims Association. For policies effective July 1, 2007 to June 30, 2008, the required retention is $420,000.

Competition.The property and casualty insurance industry is highly competitive on the basis of both price and service. There are numerous companies competing for the categories of business underwritten by Harleysville Group in the geographic areas where Harleysville Group operates, many of which are substantially larger and have considerably greater financial resources than Harleysville Group. In addition, because the insurance products of Harleysville Group and the Mutual Company are marketed exclusively through independent insurance agencies, most of which represent more than one company, Harleysville Group faces competition within each agency.

Marketing.Harleysville Group markets its insurance products through independent agencies and monitors the performance of these agencies relative to many factors including profitability, growth and retention. At December 31, 2007, there were approximately 1,500 agencies.

Investments

An important element of the financial results of Harleysville Group is the return on invested assets. An investment objective of Harleysville Group is to maintain a widely diversified fixed maturities portfolio structured to maximize after-tax investment income while minimizing credit risk through investments in high quality instruments. An objective also is to provide adequate funds to pay claims without forced sales of investments. At December 31, 2007, substantially all of Harleysville Group’s fixed maturity investment portfolio was rated investment grade and the investment portfolio did not contain any real estate or mortgage loans. Harleysville Group also invests in equity securities with the objective of capital appreciation.

Harleysville Group has adopted and follows an investment philosophy which precludes the purchase of non-investment grade fixed income securities. However, due to uncertainties in the economic environment, it is possible that the quality of investments held in Harleysville Group’s portfolio may change.

Harleysville Group invests in both taxable and tax-exempt fixed income securities as part of its strategy to maximize after-tax income. Such strategy considers, among other factors, the impact of the alternative minimum tax. Tax-exempt bonds made up approximately 28%, 27% and 36% of the total investment portfolio at December 31, 2007, 2006 and 2005, respectively.

Regulation

Insurance companies are subject to supervision and regulation in the states in which they transact business. Such supervision and regulation relate to numerous aspects of an insurance company’s business and financial condition. The purpose of such supervision and regulation is the protection of policyholders. The extent of such supervision and regulation varies, but generally derives from state statutes which delegate regulatory, supervisory and

administrative authority to state insurance departments. Accordingly, the authority of the state insurance departments typically includes the establishment of standards of solvency which must be met and maintained by insurers, the licensing to do business of insurers and agents, the nature of and limitations on investments, the approval process for premium rates for property and casualty insurance, the provisions which insurers must make for current losses and future liabilities, the deposit of securities for the benefit of policyholders and the approval of policy forms. Such insurance departments also conduct periodic examinations of the affairs of insurance companies and require the filing of annual and other reports relating to the financial condition of insurance companies.

All of the states in which Harleysville Group and the Mutual Company do business have guaranty fund laws under which insurers doing business in such states can be assessed up to 2% of annual premiums written by the insurer in that state in order to fund policyholder liabilities of insolvent insurance companies. Under these laws in general, an insurer is subject to assessment, depending upon its market share of a given line of business, to assist in the payment of policyholder and third party claims against insolvent insurers.

State laws also require Harleysville Group to participate in involuntary insurance programs for automobile insurance, as well as other property and casualty lines, in states in which Harleysville Group writes such lines. These programs include joint underwriting associations, assigned risk plans, fair access to insurance requirements (FAIR) plans, reinsurance facilities and wind storm plans. These state laws generally require all companies that write lines covered by these programs to provide coverage (either directly or through reinsurance) for insureds who cannot obtain insurance in the voluntary market. The legislation creating these programs usually allocates a pro rata portion of risks attributable to such insureds to each company on the basis of direct written premiums or the number of automobiles insured. Generally, state law requires participation in such programs as a condition to doing business. The loss ratio on insur ance written under involuntary programs generally has been greater than the loss ratio on insurance in the voluntary market.

State insurance holding company acts regulate insurance holding company systems. Each insurance company in the holding company system is required to register with the insurance supervisory agency of its state of domicile and furnish certain information concerning transactions between companies within the holding company system that may materially affect the operations, management or financial condition of the insurer within the system, including the payment of dividends from the insurance subsidiaries to the Company.

Insurance holding company acts require that all transactions involving any insurer within the holding company system, including those involving the Mutual Company and the Company’s insurance subsidiaries, must be fair and equitable to that insurer. Further, approval of the applicable insurance commissioner is required prior to the consummation of a transaction affecting the control of an insurer.

The Terrorism Risk Insurance Act of 2002 (the Act) established a program that provides a backstop for insurance-related losses resulting from any act of terrorism as defined. The Act, originally set to expire in 2005, was extended through December 31, 2007 in December 2005. The Act was extended again through December 31, 2014 in December 2007 and retitled as the Terrorism Risk Insurance Program Reauthorization Act (TRIPRA) of 2007. Under the program, the federal government will pay 85% of covered losses after an insurer’s losses exceed a deductible determined by a statutorily prescribed formula, up to a combined annual aggregate limit for the federal government and all insurers of $100 billion. If an act of terrorism or acts of terrorism result in covered losses exceeding the $100 billion annual limit, insurers with losses exceeding their deductibles will not be responsible for additional losse s. The triggering threshold for certifying an act of terrorism is $100 million in 2007 through 2014. TRIPRA adds coverage for domestic acts of terror, in addition to foreign acts of terror covered under the previous act.

The statutory formula for determining a company’s deductible for each year is based on the company’s direct commercial earned premiums for the prior calendar year multiplied by a specified percentage. These percentages are 20% for 2007 through 2014. The following lines of business are excluded from coverage and are not to be included in the deductible calculation: commercial auto, burglary and theft, surety, professional liability and farmowners’ multiperil insurance. Based on the Company’s insurance subsidiaries 2007 earned premiums for lines subject to the Act, our 2008 deductible would be $102 million.

The Act and TRIPRA require all property and casualty insurers to make terrorism insurance coverage available in all of their covered commercial property and casualty insurance policies (as defined in the Act).

In the event the Act is not renewed beyond 2014, or is renewed in a materially different form, the Company may have to attempt to obtain appropriate reinsurance for the related terrorism risk, seek exclusion from coverage related to terrorism exposure from the appropriate regulatory authorities, limit certain of its writings, or pursue a solution encompassing aspects of one or more of the foregoing.

The insurance industry has received adverse publicity about alleged anti-competitive activities by certain insurance brokers and insurers. Harleysville Group primarily distributes its products through its agents and writes approximately 2% of its premiums through brokers.

The property and casualty insurance industry has been subject to significant public scrutiny and comment primarily due to concerns regarding solvency issues, rising insurance costs, and the industry’s methods of operations. Accordingly, regulations and legislation may be adopted or enacted: to provide a greater role for the federal government in regulation of insurance companies; to strengthen state oversight, particularly in the field of solvency and investments; to further restrict an insurer’s flexibility in underwriting and pricing risks; and to impose new taxes and assessments. It is not possible to predict whether, in what form or in what jurisdictions, any of these measures might be adopted or the effect, if any, on Harleysville Group.

The Company’s insurance subsidiaries generally are restricted by the insurance laws of their respective states of domicile as to the amount of dividends they may pay to the Company without the prior approval of the respective state regulatory authorities. Generally, the maximum dividend that may be paid by an insurance subsidiary during any year without prior regulatory approval is limited to a stated percentage of that subsidiary’s statutory surplus as of a certain date, or adjusted net income of the subsidiary, for the preceding year. Applying the current regulatory restrictions as of December 31, 2007, $112.2 million would be available for distribution to Harleysville Group Inc. after June 5, 2008 without prior approval. The Company’s insurance subsidiaries paid dividends to the Company of $63.0 million in 2007 and $15.0 million in 2005. No dividends were paid in 2006. An additiona l $54.6 million of dividends were declared in 2007 and remain unpaid at December 31, 2007.

Various states have adopted the National Association of Insurance Commissioners (NAIC) risk-based capital (RBC) standards that require insurance companies to calculate and report statutory capital and surplus needs based on a formula measuring underwriting, investment and other business risks inherent in an individual company’s operations. These RBC standards have not affected the operations of Harleysville Group since each of the Company’s insurance subsidiaries has statutory capital and surplus in excess of RBC requirements.

Harleysville Group is required to file financial statements for its subsidiaries, prepared by using statutory accounting practices, with state regulatory authorities. The adjustments necessary to reconcile net income and shareholders’ equity determined by using SAP to net income and shareholders’ equity determined in accordance with GAAP are as follows:

Business - Relationship with the Mutual Company

Harleysville Group’s operations are interrelated with the operations of the Mutual Company due to the pooling arrangement and other factors. The Mutual Company owned approximately 53% of the issued and outstanding common stock of Harleysville Group Inc. at December 31, 2007. Harleysville Group employees provide a variety of services to the Mutual Company and its wholly owned subsidiaries. The cost of facilities and employees required to conduct the business of both companies is charged on a cost-allocated basis. Harleysville Group also manages the operations of the Mutual Company and its wholly owned subsidiaries pursuant to a management agreement which commenced January 1, 1993 under which Harleysville Group receives a management fee. Harleysville Group received
$6.3 million, $6.4 million, and $6.7 million for the years ended December 31, 2007, 2006 and 2005, respectively, for all such management services.

All of the Company’s officers are officers of the Mutual Company, and six of the Company’s nine directors are directors of the Mutual Company. A coordinating committee exists to review and evaluate the pooling agreement and other material transactions between Harleysville Group and the Mutual Company and is responsible for matters involving actual or potential conflicts of interest between the two companies. The coordinating committee currently consists of seven non-employee directors, three from Harleysville Group Inc. and three from the Mutual Company all of whom are not members of both Boards and one, a non-voting Chairman, who is a member of both Boards. The decisions of the coordinating committee are binding on the two companies. No intercompany transaction can be authorized by the coordinating committee unless the Company’s committee members conclude that such transaction is fair and equitable to Harleysvill e Group.

The Mutual Company leases the home office from a company subsidiary and it shares most of the facility with Harleysville Group. Rental income under the lease was $4.1 million for 2007 and 2006, and $4.0 million for 2005. Harleysville Group believes that the lease terms are no less favorable to it than if the property were leased to a non-affiliate.

In connection with the acquisition of Mid-America and HIC New York, the Company borrowed approximately $18.5 million from the Mutual Company. See Note 7 of the Notes to Consolidated Financial Statements. For additional information with respect to transactions with the Mutual Company, see Note 2 of the Notes to Consolidated Financial Statements.

The Company’s insurance subsidiaries participate in an underwriting pooling arrangement with the Mutual Company. Harleysville Group’s participation was 72% for all years presented. See “Management’s Discussion and Analysis of Results of Operations and Financial Condition” and Note 2(a) of the Notes to Consolidated Financial Statements.

Item 7.

Management’s Discussion and Analysis of Financial Condition and Results of Operations.

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, legislative and regulatory developments. These forward-looking statements are subject to change and uncertainty which 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. There can be no assurance that future developments will be in accordance with management’s expectations or that the effect of future developments on Harleysville Group will be those anticipated by management. Actual financial results, including premium levels and underwriting res ults, 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; competition in insurance product pricing; government regulation and changes therein which may impede the ability to charge adequate rates; performance of the financial markets; fluctuations in interest rates; availability and price of reinsurance; the A. M. Best rating of Harleysville Group; and the status of labor markets in which the Company operates. In addition, see “Management’s Discussion and Analysis - Risk Factors.”

Overview

The Company’s net income is primarily determined by three elements:

net premium income

investment income

amounts paid or reserved to settle insured claims

Variations in premium income are subject to a number of factors, including

limitations on premium rates arising from the competitive market place or regulation

limitations on available business arising from a need to maintain the quality of underwritten risks

the Company’s ability to maintain its A- (“excellent”) rating by A.M. Best

the ability of the Company to maintain a reputation for efficiency and fairness in claims administration

Variations on investment income are subject to a number of factors, including

general interest rate levels

specific adverse events affecting the issuers of debt obligations held by the Company

changes in the prices of equity securities generally and those held by the Company specifically

Loss and loss settlement expenses are affected by a number of factors, including

the quality of the risks underwritten by the Company

the nature and severity of catastrophic losses

the availability, cost and terms of reinsurance

underlying settlement costs, including medical and legal costs

The Company seeks to manage each of the foregoing to the extent within its control. Many of the foregoing factors are partially, or entirely, outside of the control of the Company.

Critical Accounting Policies and Estimates

The consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles, which require Harleysville Group to make estimates and assumptions (see Note 1 of the Notes to Consolidated Financial Statements). Harleysville Group believes that of its significant accounting policies, the following may involve a higher degree of judgment and estimation. The judgments, or the methodology on which the judgments are made, are reviewed quarterly with the Audit Committee.

Liabilities for Losses and Loss Settlement Expenses. The liability for losses and loss settlement expenses represents estimates of the ultimate unpaid cost of all losses incurred, including losses for claims which have not yet been reported to Harleysville Group. The amount of loss reserves for reported claims is based primarily upon a case-by-case evaluation of the type of risk involved, knowledge of the circumstances surrounding each claim and the insurance policy provisions relating to the type of loss. The amounts of loss reserves for unreported claims and loss settlement expense reserves are determined utilizing historical information by line of insurance as adjusted to current conditions. Inflation is implicitly provided for in the reserving function through analysis of costs, trends and reviews of historical reserving results. Estimates of the liabilities are reviewed and updated on a regular basis using the most r ecent information on reported claims and a variety of actuarial techniques. It is expected that such estimates will be more or less than the amounts ultimately paid when the claims are settled. Changes in these estimates are reflected in current operations.

Investments. Generally, unrealized investment gains or losses on investments carried at fair value, net of applicable income taxes, are reflected directly in shareholders’ equity as a component of comprehensive income and, accordingly, have no effect on net income. However, if the fair value of an investment declines below its cost and that decline is deemed other than temporary, the amount of the decline below cost is charged to earnings. Harleysville Group monitors its investment portfolio and at least quarterly reviews investments that have experienced a decline in fair value below cost to evaluate whether the decline is other than temporary. Such evaluations consider, among other things, the magnitude and reasons for a decline, the prospects for the fair value to recover in the near term and Harleysville Group’s ability and intent to retain the investment for a period of time sufficient to allow for a recove ry in value. Future adverse investment market conditions, or poor operating results of underlying investments, could result in an impairment charge in the future.

Harleysville Group has written down to fair value, without exception, any equity security that has declined below cost by more than 20% and maintained such decline for six months, or by 50% or more, in the quarter in which either such decline occurred. In some cases, securities that have declined by a lesser amount or for a shorter period of time are written down if the evaluation indicates the decline is other than temporary. Fair value of equity securities is based on the closing market value. The fair value of mutual fund holdings is based on the closing net asset value reported by the fund. The fair value of fixed maturities is based upon data supplied by an independent pricing service. It can be difficult to determine the fair value of non-traded securities but Harleysville Group does not own a material amount of non-traded securities.

Policy Acquisition Costs. Policy acquisition costs, such as commissions, premium taxes and certain other underwriting and agency expenses that vary with and are primarily related to the production of business, are deferred and amortized over the effective period of the related insurance policies and in proportion to the premiums earned. The method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. The estimation of net realizable value takes into account the premium to be earned, related investment income over the claim paying period, expected losses and loss settlement expenses, and certain other costs expected to be incurred as the premium is earned. Future changes in estimates, the most significant of which is expected losses and loss settlement expenses, may require adjustments to deferred policy acquisition costs. If the estimation of net realizable value indicates that the acquisition costs are unrecoverable, further analyses are completed to determine if a reserve is required to provide for losses that may exceed the related unearned premiums.

Contingencies. Besides claims related to its insurance products, Harleysville Group is subject to proceedings, lawsuits and claims in the normal course of business. Harleysville Group assesses the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. There can be no assurance that actual outcomes will be consistent with those assessments.

The application of certain of these critical accounting policies to the years ended December 31, 2007 and 2006 is discussed in greater detail below.

Results of Operations

Harleysville Group underwrites property and casualty insurance in both the personal and commercial lines of insurance. The personal lines of insurance include both auto and homeowners, and the commercial lines include auto, commercial multi-peril and workers compensation. The business is marketed primarily in the eastern and midwestern United States through independent agents.

Historically, Harleysville Group’s results of operations have been influenced by factors affecting the property and casualty insurance industry in general. The operating results of the United States property and casualty insurance industry have been subject to significant variations due to competition, weather, catastrophic events, regulation, the availability and cost of satisfactory reinsurance, general economic conditions, judicial trends, fluctuations in interest rates and other changes in the investment environment.

Harleysville Group’s premium growth and underwriting results have been, and continue to be, influenced by market conditions. Insurance industry price competition has often made it difficult both to obtain and to retain properly priced personal and commercial lines business. It is management’s policy to continue to maintain its underwriting standards.

The key elements of Harleysville Group’s business model are the sales of properly priced and underwritten personal and commercial property and casualty insurance through independent agents and the investment of the premiums in a manner designed to assure that claims and expenses can be paid while providing a return on the capital employed. Loss trends and investment performance are critical factors in influencing the success of the business model. These factors are affected by the factors impacting the insurance industry in general as described above and factors unique to Harleysville Group as described in the following discussion.

Transactions with Affiliates

The Company’s property and casualty subsidiaries participate in a pooling agreement with the Mutual Company. The pooling agreement provides for the allocation of premiums, losses, loss settlement expenses and underwriting expenses between Harleysville Group and the Mutual Company. Harleysville Group is not liable for any losses incurred by the Mutual Company, Preferred and HNJ prior to January 1, 1986, the date the pooling agreement became effective. Harleysville Group’s participation in the pool has been 72% since January 1, 1998.

Effective January 1, 2008, the Company’s property and casualty subsidiaries and the Mutual Company and its property and casualty subsidiary, Harleysville Pennland Insurance Company (Pennland) amended their intercompany pooling agreement to increase Harleysville Group’s share of the pool from 72% to 80%. Harleysville Group received cash and investments of $192.1 million on January 3, 2008 associated with the transfer of assets and liabilities from the Mutual Company and Pennland to Harleysville Group in connection with the pool change.

When the Company’s subsidiaries’ pooling participation increases, there is a larger retrocession of this pooled business from the Mutual Company. Through this retrocession, Harleysville Group is assuming a larger share of premiums, losses and underwriting expenses for current and future periods originating both from its subsidiaries and the Mutual Company. An increase in Harleysville Group’s pooling participation results in a larger share of the pooled liabilities being assumed by Harleysville Group. Cash and investments are received by Harleysville Group equal to this greater share of loss reserves, unearned premiums and other insurance liabilities (primarily commissions and premium taxes) less a ceding commission based on acquisition costs related to unearned premiums. An increase in pool participation also increases Harleysville Group’s leverage and exposure to prior period development.

Because the pooling agreement does not relieve Harleysville Group of primary liability as the originating insurer, there is a concentration of credit risk arising from business ceded to the Mutual Company. However, the pooling agreement provides for the right of offset and the amount of credit risk with the Mutual Company was not material at December 31, 2007 and 2006, and is not expected to be materially different after the pool change effective January 1, 2008. The Mutual Company has an A. M. Best rating of “A-” (Excellent).

Harleysville Group has attempted to reduce the potential impact of future catastrophes by achieving greater geographic distribution of risks, reducing exposure in catastrophe-prone areas and through reinsurance, including an agreement with the Mutual Company. Effective January 1, 1997, Harleysville Group entered into a reinsurance agreement with Mutual Company whereby the Mutual Company, in return for a reinsurance premium, reinsured accumulated catastrophe losses up to $14.4 million in a quarter for 2005. This reinsurance coverage was in excess of a retention of $3.6 million in a quarter for 2005. The agreement excluded catastrophe losses resulting from earthquakes,

terrorism or hurricanes, and supplemented the existing external catastrophe reinsurance program. The premiums for this reinsurance were established in consultation with an independent actuarial firm. The agreement was terminated December 31, 2005 and coverage was not placed as it is no longer deemed necessary based on the current catastrophe risk profile. Under this agreement, Harleysville Group ceded premiums earned of $8.8 million and losses incurred of $(0.2) million to the Mutual Company in 2005.

Harleysville Ltd. is a subsidiary of the Company and leases the home office to the Mutual Company, which shares the facility with Harleysville Group. Rental income under the lease was $4.1 million, $4.1 million and $4.0 million for 2007, 2006 and 2005, respectively, and is included in other income after elimination of intercompany amounts of $2.5 million in 2007, $2.5 million in 2006 and $2.4 million in 2005. The lease has a five-year term expiring December 31, 2009 and includes a formula for additional rent for any additions, improvements or renovations. The Mutual Company is responsible for the building operating expenses including maintenance and repairs. The pricing of the lease was based upon an appraisal obtained from an independent real estate appraiser.

Harleysville Group provides certain management services to the Mutual Company and other affiliates. Harleysville Group received a fee of $6.3 million, $6.4 million and $6.7 million in 2007, 2006 and 2005, respectively, for its services under these management agreements. Under related agreements, Harleysville Group serves as the paymaster for Harleysville companies, with each company being charged for its proportionate share of salary and employee benefits expense based upon time allocation. The level of fees has been approved by each state insurance department having jurisdiction.

The Company’s insurance subsidiaries and the Mutual Company are party to an Equipment and Supplies Allocation Agreement whereby equipment and supplies are shared between parties. Ultimate expense for such items is allocated to Harleysville Group based on its pooling participation. The Mutual Company has purchased and developed certain equipment and software which is expensed by Harleysville Group based on its pooling participation as the items are depreciated or amortized.

Harleysville Group borrowed $18.5 million from the Mutual Company in connection with the acquisition of Mid-America and HIC New York in 1991. It was a demand loan with a stated maturity in March 1998 which had been extended to March 2005. In February 2005, the maturity was extended again to March 2012 and the interest rate became LIBOR plus 0.45%, which was a commercially reasonable market rate in 2005. Interest expense on this loan was $1.1 million, $1.0 million and $0.7 million in 2007, 2006 and 2005, respectively.

Harleysville Group has no material relationships with current or former members of management other than compensatory plans and arrangements disclosed or described in the Company’s public filings.

Off Balance Sheet Arrangements

Harleysville Group has off-balance-sheet credit risk related to approximately $78.0 million and $77.0 million of premium balances due to the Mutual Company from agents and insureds at December 31, 2007 and 2006, respectively.

Premiums earned decreased $5.8 million for the year ended December 31, 2007. The decrease was primarily composed of a decrease in premiums earned for commercial lines of $3.7 million and a decrease of $2.1 million in personal lines premiums earned. The decrease in premiums earned for commercial lines was primarily due to a decrease in commercial auto premiums earned due to fewer policy counts and a decrease in earned premiums assumed from involuntary pools. The decline in premiums earned for personal lines was primarily due to fewer policy counts. The reduction in personal lines volume was driven primarily by a reduction of personal automobile business from the continued implementation of more stringent underwriting processes, partially offset by an increase in homeowners business due to higher average premiums.

Investment income increased $8.2 million for the year ended December 31, 2007, resulting from an increase in invested assets and a greater percentage of invested assets in fixed maturity securities.

Net realized investment gains decreased $39.7 million for the year ended December 31, 2007, primarily due to gains on the sale of equity securities in the second quarter of 2006.

There were impairment charges of $1.4 million in 2007 and no impairment charges in 2006.

In April 2007, bonds with an amortized cost of $1,882,000 were transferred from the held to maturity category to the available for sale category due to a significant deterioration in the credit worthiness of the issuer. An impairment loss of $118,000 was recognized on this security. The security was sold in the third quarter of 2007 at a gain of $76,000.

Harleysville Group holds securities with unrealized losses at December 31, 2007 as follows:


	Fair Value		Unrealized Loss		Length of Unrealized Loss
	Fair Value		Unrealized Loss		Less Than 12 Months		Over 12 Months
	(in thousands)
Fixed maturities:
U.S. Treasury securities and obligations of U.S. government corporations and agencies	$	19,022	$	79	$	24	$	55
Obligations of states and political subdivisions		104,500		914		66		848
Corporate securities		278,961		4,323		1,898		2,425
Mortgage-backed securities		123,788		1,674		570		1,104
Total fixed maturities	$	526,271	$	6,990	$	2,558	$	4,432
Equity securities	$	7,861	$	241	$	241

Of the total fixed maturity securities with an unrealized loss at December 31, 2007, securities with a fair value of $424.0 million and an unrealized loss of $5.9 million are classified as available for sale and are carried at fair value on the balance sheet while securities with a fair value of $102.3 million and an unrealized loss of $1.1 million are classified as held to maturity on the balance sheet and are carried at amortized cost.

The fixed maturity investments with continuous unrealized losses for less than twelve months were primarily due to a widening of credit spreads rather than a decline in credit quality. There are $323.1 million in fixed maturity securities, at fair value, that at December 31, 2007, had been below amortized cost for over twelve months. The $4.4 million of unrealized losses on such securities primarily relates to securities which carry investment grade ratings and have declined in fair value roughly in line with market interest rate changes. Harleysville Group currently has the ability and intent to hold these securities at least until recovery.

There are four positions that comprise the unrealized loss in equity investments at December 31, 2007. They have not been below cost for significant continuous amounts of time. Harleysville Group has been monitoring these securities and it is possible that some may be written down in the income statement in the future.

Income before income taxes and cumulative effect of accounting change decreased $13.4 million for the year ended December 31, 2007 compared to the prior year. The decrease was primarily due to a decrease in realized investment gains, partially offset by the increase in investment income and improved underwriting results.

The improved underwriting results in 2007 were primarily due to lower loss severity, lower catastrophe losses and lower underwriting expenses.

An insurance company’s statutory combined ratio is a standard measure of underwriting profitability. This ratio is the sum of (1) the ratio of incurred losses and loss settlement expenses to net earned premium, (2) the ratio of expenses incurred for commissions, premium taxes, administrative and other underwriting expenses to net written premium, and (3) the ratio of dividends to policyholders to net earned premium. The combined ratio does not reflect investment income, federal income taxes or other non-operating income or expense. A ratio of less than 100 percent generally indicates underwriting profitability. Harleysville Group’s statutory combined ratio decreased to 96.7% for the

year ended December 31, 2007 from 98.6% for the year ended December 31, 2006. Such decrease was due to improved underwriting results in commercial lines, partially offset by a lower underwriting gain in personal lines.

The statutory combined ratios by line of business for the year ended December 31, 2007 as compared to the year ended December 31, 2006 were as follows:


	For the Year Ended December 31,
	2007		2006
Commercial:
Automobile		94.7%		99.3%
Workers compensation		112.2%		117.2%
Commercial multi-peril		97.8%		98.9%
Other commercial		83.8%		86.6%
Total commercial		97.5%		100.3%
Personal:
Automobile		99.7%		99.3%
Homeowners		86.8%		82.6%
Other personal		79.8%		69.8%
Total personal		92.7%		90.6%
Total personal and commercial		96.7%		98.6%

The commercial lines statutory combined ratio decreased to 97.5% for the year ended December 31, 2007 from 100.3% for the year ended December 31, 2006. The decrease is primarily due to declines in the combined ratio for all lines of business. Favorable prior accident year development as well as improved underwriting results in the current accident year contributed to the decreases in the commercial auto and commercial multi-peril lines of business. The decrease in the commercial auto combined ratio was primarily due to the recognition of favorable development of $10.2 million in 2007, while favorable development of $5.1 million was recognized in 2006. The decrease in the commercial multi-peril combined ratio was due to improved underwriting results in the current accident year. The decrease in the workers compensation combined ratio was primarily due to improved underwriting results in the current acciden t year.

The personal lines statutory combined ratio increased to 92.7% for the year ended December 31, 2007 from 90.6% for the year ended December 31, 2006 primarily due to less favorable underwriting results in the current accident year.

Reserves for unpaid losses and loss settlement expenses are estimated for case reserves and losses incurred but not reported (IBNR) separately. The sum of case reserves and IBNR represents the Company’s estimate of total unpaid loss and loss settlement expense. Case reserves are determined for each reported claim by the Company’s claims organization reflecting the known circumstances of the individual claim. The Company’s actuaries calculate IBNR by reducing their estimate of ultimate loss and loss settlement expense by cumulative paid loss and loss settlement expense and case reserves. Ultimate losses are re-estimated for each line of business on a quarterly basis using the most current loss and claim data as of the quarter end.

In addition to analyzing reserves on a line of business basis, reserving categories are identified and reviewed. For example, the following categories for the Commercial Auto Liability line of business are analyzed quarterly: Commercial Auto Liability Bodily Injury; Commercial Auto Liability Property Damage; and Commercial Auto Liability Excess. In the discussion that follows, these categories are referred to by the label “line of business.”

In the course of our quarterly reserve estimation process, several standard loss reserving methods and procedures are utilized to derive estimates of ultimate loss for each line of business, including:

Paid Loss Development Method

Incurred Loss Development Method

Incurred Counts and Averages Method (Based on Exponential Fit of Severity)

Bornhuetter-Ferguson Method

Any individual method used to estimate loss reserves has its advantages and disadvantages based on trends, changes within the external business environment, changes in internal company processes and procedures and any bias that may be inherent in the methodology. The actuaries give consideration to the relative strengths and weaknesses of each of the methods to derive a selected point estimate within the range. Following is a general description of each of the methods used:

Paid Loss Development Method:The Paid Loss Development Method uses historical payment patterns to project future payments as of a given evaluation date to ultimate loss. Estimates using this method are not affected by changes in case reserving practices that might have occurred during the review period, but may be understated as this method does not take into account large unpaid claims. This method is also susceptible to any changes in the rate of claim settlements or shifts in the size of claims settled.

A number of indications of ultimate loss may be produced from the Paid Loss Development Method since a number of loss development factors (LDFs) may be selected. The actuaries produce and review several indications of ultimate loss using this method based on various LDF selections as judged appropriate, such as

3-Year Average (straight average and loss-weighted average)

5-Year Average (straight average and loss-weighted average)

5-Year Excluding Highest and Lowest LDFs

All-Year loss-weighted average

Selected LDF Pattern (LDFs are selected for each evaluation based on the actuaries’ review of the historical development)

Incurred Loss Development Method:The Incurred Loss Development Method is similar to the paid method, but instead uses historical incurred (case reserves plus payments) patterns to project future incurred losses as of a given evaluation date to ultimate loss. In many cases, the incurred development method is preferred over the paid method as it includes the additional information provided by the aggregation of individual case reserves. The resulting LDFs tend to be lower and more stable than those of the paid development method. However, the incurred development method may be affected by changes in case reserving practices and any unusually large individual claims.

As with the Paid Loss Development Method, various indications of ultimate loss may be produced from the Incurred Loss Development Method. The actuaries produce and review several indications of ultimate loss using this method based on various LDF selections.

Incurred Counts and Averages Method:This method is used to estimate ultimate loss by separately estimating ultimate counts and severity (average loss per claim) components of ultimate loss. Both the ultimate claim counts and ultimate severity are estimated using a loss development factor approach similar to the Incurred Loss Development Method. For this reason, the same considerations discussed in the Incurred Loss Development Method apply to this method as well.

An ultimate severity is selected by fitting an exponential curve to the historical ultimate severities indicated using the ratio of the ultimate loss and ultimate claim counts. This method yields ultimate severities that are based on the underlying historical trends in the data. Ultimate claim counts and ultimate severities are multiplied together to produce an estimate of ultimate losses.

This method is useful in more recent accident years where the data is not mature and is especially useful when loss development patterns are volatile or not well established.

Bornhuetter-Ferguson Method: The Bornhuetter-Ferguson Method is a blended method that explicitly takes into account both actual loss development to date and expected future loss emergence. Two versions of this method exist: one based on paid loss and one based on incurred loss. This method uses the selected loss development patterns from the Development Methods to calculate the expected percentage of loss unpaid (or unreported). The expected component of the method is calculated by multiplying earned premium for the given exposure period by a selecteda priori loss ratio. The resulting dollars are then

multiplied by the expected percentage of unpaid (or unreported) loss described above. This provides an estimate of future loss payments (or reporting) that is then added to actual paid (or incurred) loss data to produce estimated ultimate loss.

Each of the methodologies described above (and their derivatives) are reviewed for each line of business. This approach allows the actuaries to identify and respond to the unique characteristics of each line of business. Further, since long-term historical data is reviewed, changes in development patterns within a line of business may likewise be identified and considered in the actuaries’ process of selecting ultimate loss.

An actuarial best estimate of ultimate loss is selected for each line of business based on a review of the indications produced by the above methodologies. More consideration is given to those methods that the actuaries deem to be more appropriate in a particular situation. In addition, other metrics such as claim closing ratios, average case reserve levels, paid loss to incurred loss ratios, individual large loss information, and recent insurance pricing changes are reviewed to help the actuaries select the most appropriate estimates of ultimate loss.

The selection of the ultimate loss is based on information unique to each line of business and accident year and the judgment and expertise of the actuaries.

Short-Tail versus Long-Tail Lines of Business:The reserving methods described above are generally applied to each line of business, regardless of their classification as short-tail or long-tail. “Tail” refers to the time period between the occurrence of a loss and the final settlement of the claim. The merits of an individual reserving method relative to the line of business and age of accident period are considered in the actuaries’ process of selecting ultimate loss.

Short-tail lines of business, by definition, develop to their ultimate value faster than long-tail lines of business. Property coverages including inland marine along with automobile physical damage coverages are considered short-tail lines of business. Automobile Liability, General Liability, Commercial Multi-Peril Liability and Workers’ Compensation are considered long-tail lines of business. For many liability claims, significant periods of time may elapse between the occurrence of the loss, the reporting of the loss, and the final settlement of the claim. Workers’ Compensation claims can result in providing medical benefits and wage replacement over the course of an injured worker’s lifetime.

In general, more consideration may be given to the results of the development methodologies for short-tail lines than to long-tail lines for accident periods of the same maturity. For example, the indicated ultimate loss using the Incurred Loss Development Method for the most recent accident year is generally considered more reliable for a short-tail line, such as Homeowners Property than a long-tail line, such as Workers’ Compensation.

As mentioned previously, the selection of ultimate loss is based on information unique to each line of business and accident year subject to exceptions, such as the emergence of one or more unusually large claims in a particular accident period for a short-tail line. In this case, the indications produced by the development methods may be overstated (due to development of ultimate losses in excess of policy limits) and such information would be considered in the actuaries’ process of selecting ultimate loss.

Immature Accident Periods:The Paid Loss Development Method is generally given less consideration than the Incurred Loss Development Method for less mature accident periods since the relatively low magnitude of losses paid at early evaluations tends to result in less reliable indications from the Paid Loss Development Method.For long-tail lines of business, neither the Incurred nor the Paid Loss Development methods may receive much consideration for the most recent accident period. This is due to the fact that the relatively low magnitude of losses either incurred or paid at early evaluations tends to result in less reliable indications from these methods.

In faster developing, short-tailed lines such as Auto Physical Damage, Special Property, Homeowners, Commercial Multi-Peril Property and Property Damage, the Paid Loss Development Method, the Incurred Loss Development Method and the Bornhuetter-Ferguson methods are primarily used as they typically produce tightly clustered projections for all accident years.

The estimation of loss reserves for long-tail lines such as Commercial Auto Liability, Commercial Multi-Peril Liability, and Workers’ Compensation is more complex and is subject to a higher degree of variability than for short-tail lines of business.

In 2007, Harleysville Group recognized net favorable development of $22.0 million in the provision for insured events of prior years, primarily due to lower-than-expected claims severity broadly experienced across all casualty lines in accident years 2003 through 2006, partially offset by adverse development in prior accident years.

A reduction in commercial automobile severity was broadly observed during 2007 and led to the recognition of $10.2 million of favorable development in this line in 2007.

A reduction in workers compensation severity in the aggregate in accident years 2004 through 2006 was observed during 2007 and led to the recognition of favorable development for those accident years in 2007. An increase in workers compensation medical severity in accident years 2003 and prior was observed during 2007 and led to the recognition of adverse development for those accident years in 2007. In total, $0.1 million in adverse development was recognized in the workers compensation line during 2007.

A reduction in commercial multi-peril severity in accident years 2005 and 2006 was observed during 2007 and contributed to the recognition of favorable development for those accident years in 2007. An increase in commercial multi-peril severity in the liability portion of the line in accident years prior to 2005 was observed during 2007 and contributed to the recognition of adverse development for those accident years in 2007. In total, $2.1 million in favorable development was recognized in the commercial multi-peril line during 2007.

A reduction in personal automobile severity was broadly observed during 2007 and led to the recognition of $5.7 million of favorable development in this line in 2007.

A reduction in homeowners severity was broadly observed during 2007 and led to the recognition of favorable development of $4.1 million in this line in 2007.

The tables below break out the change in the estimate of ultimate losses between December 31, 2006 and December 31, 2007 for the 2006, 2005, 2004 and 2003 accident years into severity and frequency components for the major commercial and personal lines of business. Table 1 summarizes the Company’s percentage change in the estimate of ultimate loss and loss settlement expense by line of business between December 31, 2006 and December 31, 2007. Tables 2 and 3 summarize the Company’s percentage change in the estimate of ultimate severity and ultimate claim counts, respectively. The relationship between the three tables is as follows: (1+ the % change in estimated ultimate loss) = (1+ the % change in estimated ultimate severity) x (1+ the % change in estimated ultimate claim counts). The estimated ultimate severity is calculated as the ratio of estimated ultimate loss to estimated ultimate claim counts. The amounts underlying these tables are based on direct loss and claim experience minus ceded loss experience and exclude a small portion of losses associated with business assumed from involuntary pools.

These tables illustrate that the changes to the Company’s estimates of ultimate loss for prior accident years between December 31, 2006 and December 31, 2007 are primarily driven by the severity component of loss. One exception to this is accident years 2003 and 2004 for total commercial lines. In this year, favorable prior year development was primarily due to favorable claim count development and partially offset by adverse development in claim severity. In this context, the term “severity” does not refer to an actuarial assumption, rather, it refers to “severity” as a descriptive statistic derived from the ratio of estimated ultimate loss to estimated ultimate claim counts. Broadly speaking, as estimates of the ultimate number of claims were relatively stable for the prior accident periods, the changes in estimates of ultimate loss are characterized as resulting from a reduction in sever ity.

The following table presents workers compensation claim count information for the total pooled business in which Harleysville Group participates and payment amounts which are Harleysville Group’s pooling share of the total pooled amounts:


	For the year ended December 31, 2007			For the year ended December 31, 2006
	(dollars in thousands)
Number of claims pending, beginning of period		5,481			6,020
Number of claims reported		8,531			8,601
Number of claims settled or dismissed		(8,684	)		(9,140	)
Number of claims pending, end of period		5,328			5,481
Losses paid	$	59,322		$	55,818
Loss settlement expenses paid	$	13,091		$	12,610

Workers compensation losses primarily consist of indemnity and medical costs for injured workers.

Harleysville Group records the actuarial best estimate of the ultimate unpaid losses and loss settlement expenses incurred. The estimate represents the actuarially determined expected amount of future payments on all loss and loss settlement expenses incurred on or before December 31, 2007. Actuarial loss reserving techniques and assumptions, which rely on historical information as adjusted to reflect current conditions, have been consistently applied, after including consideration of recent case reserve activity, during the periods presented. Changes in the estimate of the liability for unpaid losses and loss settlement expenses reflect actual payments and evaluations of new information and data since the last reporting date. These changes correlate with actuarial trends.

The following table presents the liability for unpaid losses and loss settlement expenses by case and incurred but not reported (IBNR) reserves by line of business and a statistically determined range of estimates of the ultimate unpaid losses and loss settlement expenses incurred for each line of business as of December 31, 2007. The range of estimates around the actuarial best estimates is statistically determined in order to provide information regarding the variability of the actuarial best estimates. The statistical analysis is completed only on a basis that is net of reinsurance recoverables, as this appropriately reflects Harleysville Group’s risk profile based on the type and quality of its reinsurance. The range is determined using the Monte Carlo Simulation method. This method uses the Company’s actual historical loss data to estimate the mean and standard deviation of a statistical distribution for future loss development. There have been no adjustments made to the historical data. The Company’s application of the Monte Carlo Simulation assumes that loss development factors are normally distributed with a mean and standard deviation derived from the historical data.

Reserve ranges are determined using both paid and incurred loss development data with a 10,000 trial simulation run against each set of data for each line of business presented in the table below. Each simulation generates a unique set of loss development factors randomly generated from the normal distribution with mean and standard deviation as defined above. Each unique set of loss development factors, when applied to the data, produces a unique reserve estimate. At the completion of the simulation, there are 20,000 unique reserve estimates which can be ordered from lowest to highest creating a range of reserve estimates. The resulting range produced by the simulation is used to create a reasonable representation of a 90% confidence interval using the 5% point as the low end of the range and the 95% point as the high end of the range. The 90% confidence interval represents the range of reserve estimates for which there is approximately a 90% probability that the actual reserve amount (which will not be known for many years) is contained within the defined range. The total commercial lines range and total personal lines range were developed as separate simulations using the means and standard deviations of the individual lines as inputs. Therefore, the 90% confidence interval for all lines of business is smaller than the straight sum of the individual lines of business 90% intervals.

The use of this technique to analyze reserve ranges assumes historical data has validity in predicting future outcomes. This assumption is consistent with a key assumption underlying much of insurance pricing and reserving theory.

Gross liability	$	577,416	$	682,351	$	286,923	$	969,274	$	1,546,690

Reinsurance receivables were $167.7 and $167.2 million at December 31, 2007 and 2006, respectively. Of these amounts, $92.1 million and $93.9 million, respectively or 55% and 56%, respectively, of the receivables were due from governmental bodies, regulatory agencies or quasi governmental pools and reinsurance facilities where, Harleysville Group believes, there is virtually no credit risk. The remainder of the reinsurance recoverables are principally due from reinsurers rated A- or higher by the A.M. Best Company.

Because of the nature of insurance claims, there are uncertainties inherent in the estimates of ultimate losses. Harleysville Group’s reorganization of its claims operation in recent years has resulted in new people and processes involved in settling claims. As a result, more recent statistical data reflects different patterns than in the past and gives rise to uncertainty as to the pattern of future loss settlements. There are uncertainties regarding future loss cost trends particularly related to medical treatments and automobile repair. Court decisions, regulatory changes and economic conditions can affect the ultimate cost of claims that occurred in the past. Accordingly, the ultimate liability for unpaid losses and loss settlement expenses will likely differ from the amount recorded at December 31, 2007.

The property and casualty industry has had substantial aggregate loss experience from claims related to asbestos-related illnesses, environmental remediation, product liability, mold, and other uncertain exposures. Harleysville Group has not experienced significant losses from such claims.

Net catastrophe losses decreased $4.7 million for the year ended December 31, 2007, primarily due to less severe catastrophes impacting Harleysville Group in 2007.

Effective for one year from July 1, 2007, the Company’s subsidiaries and the Mutual Company and its wholly owned subsidiaries renewed its catastrophe reinsurance which provides coverage ranging from 75% to 85% of up to $250.0 million in excess of a retention of $50.0 million for any given catastrophe excluding terrorism for commercial lines. Harleysville Group’s 2007 pooling share of this coverage would range from 75% to 85% of up to $180.0 million in excess of a retention of $36.0 million for any given catastrophe. Pursuant to the terms of the treaty, the maximum recovery would be $195.0 million for any catastrophe involving an insured loss equal to or greater than $300.0 million. Harleysville Group’s 2007 pooling share of this maximum recovery would be $140.4 million for any catastrophe

involving an insured loss of $216.0 million or greater. The treaty includes reinstatement provisions providing for coverage for a second catastrophe and requiring payment of an additional premium in the event of a first catastrophe occurring.

The income tax expense for the year ended December 31, 2007 includes the tax benefit of $7.2 million associated with tax-exempt income compared to $8.6 million in the prior year.

Underwriting expenses, including amortization of deferred policy acquisition costs, decreased $7.2 million for the year ended December 31, 2007 compared to the prior year. The decrease in underwriting expenses was primarily due to a decrease in head count resulting from on-going expense reduction initiatives, and lower incentive compensation, pension expense and severance charges.

Harleysville Group froze its defined benefit pension plan at the then current benefit levels as of March 31, 2006. Harleysville Group’s portion of pension expense for the plan was $0.5 million and $1.9 million for 2007 and 2006, respectively. Harleysville Group enhanced its 401(k) retirement savings plan to provide for a company contribution equal to 5% of salary for all eligible employees, effective April 1, 2006, and recognized expense of $3.7 million and $2.9 million in 2007 and 2006, respectively due to this enhancement.

Other income increased $0.2 million for the year ended December 31, 2007 primarily due to a $2.7 million gain realized on the sale of the Company’s office building in Traverse City, Michigan in the second quarter of 2007, partially offset by a decrease of $2.2 million in claim handling fees received in connection with the National Flood Insurance Program, related primarily to flood claims from Hurricane Katrina.

2006 Compared to 2005

Premiums earned decreased $2.7 million for the year ended December 31, 2006. The decrease was primarily due to a decrease in premiums earned for personal lines of $8.8 million, partially offset by an increase of $6.1 million in commercial lines premiums earned. The increase in premiums earned for commercial lines was primarily due to higher average premiums, partially offset by fewer policy counts in the commercial automobile line of business. The decline in premiums earned for personal lines was primarily due to fewer policy counts. The reduction in personal lines volume was driven primarily by a reduction of personal automobile business from the continued implementation of more stringent underwriting processes.

Investment income increased $12.1 million for the year ended December 31, 2006, resulting from an increase in invested assets, a greater percentage of invested assets in fixed maturity securities and higher interest rates on short-term investments.

Realized investment gains increased $40.4 million for the year ended December 31, 2006, primarily resulting from gains on the sale of equity securities in the second quarter of 2006.

Income before income taxes and cumulative effect of accounting change increased $77.4 million for the year ended December 31, 2006 compared to the prior year. The increase was primarily due to the increase in investment income, increased realized investment gains and improved underwriting results.

The improved underwriting results were primarily due to improved underwriting results in both commercial and personal lines.

Harleysville Group’s statutory combined ratio decreased to 98.6% for the year ended December 31, 2006 from 102.2% for the year ended December 31, 2005. Such decrease was due to improved underwriting results in both commercial lines and personal lines, primarily resulting from improved loss experience, partially offset by greater catastrophe losses and higher underwriting expenses in 2006.

The statutory combined ratios by line of business for the year ended December 31, 2006 as compared to the year ended December 31, 2005 were as follows:


	For the Year Ended December 31,
	2006		2005
Commercial:
Automobile		99.3%		101.1%
Workers compensation		117.2%		124.0%
Commercial multi-peril		98.9%		101.5%
Other commercial		86.6%		98.7%
Total commercial		100.3%		104.3%
Personal:
Automobile		99.3%		99.2%
Homeowners		82.6%		87.6%
Other personal		69.8%		72.3%
Total personal		90.6%		93.1%
Total personal and commercial		98.6%		102.2%

The commercial lines statutory combined ratio decreased to 100.3% for the year ended December 31, 2006 from 104.3% for the year ended December 31, 2005. The decrease is primarily due to declines in the combined ratio for all lines of business due to improved loss severity. The personal lines statutory combined ratio decreased to 90.6% for the year ended December 31, 2006 from 93.1% for the year ended December 31, 2005. The decrease is primarily due to improved property results in the homeowners line, partially offset by higher catastrophe losses.

In 2006, Harleysville Group recognized net favorable development of $18.1 million in the provision for insured events of prior years, primarily due to lower-than-expected claims severity in casualty lines in accident years 2002 through 2005, partially offset by adverse development in prior accident years.

automobile severity in accident year 2005 and in accident years prior to 2002 was observed during 2006 and led to the recognition of adverse development for those accident years in 2006. In total, $5.1 million in favorable development was recognized in the commercial automobile line during 2006.

A reduction in workers compensation severity in accident years 2002 through 2005 was observed during 2006 and led to the recognition of favorable development for those accident years in 2006. An increase in workers compensation medical severity in accident years 1997 through 2001 was observed during 2006 and led to the recognition of adverse development for those accident years in 2006. In total, $0.3 million in adverse development was recognized in the workers compensation line during 2006.

A reduction in commercial multi-peril severity in accident years 2002 through 2005 was observed during 2006 and led to the recognition of favorable development for those accident years in 2006. An increase in commercial multi-peril severity in the liability portion of the line in accident years prior to 2002 was observed during 2006 and led to the recognition of adverse development for those accident years in 2006. In total, $3.1 million in favorable development was recognized in the commercial multi-peril line during 2006.

A reduction in personal automobile severity for accident years 2002 through 2005 was observed during 2006 and led to the recognition of favorable development for those accident years in 2006. An increase in personal automobile severity for 1997 and prior accident years was observed during 2006 and led to the recognition of adverse development for those accident years in 2006. In total, $5.0 million of favorable development was recognized in the personal automobile line during 2006.

A reduction in homeowners severity was broadly observed during 2006 and led to the recognition of favorable development of $5.5 million in this line in 2006.

Net catastrophe losses increased $7.4 million for the year ended December 31, 2006, primarily due to more severe catastrophes impacting Harleysville Group in 2006.

Underwriting expenses, including amortization of deferred policy acquisition costs, increased $1.0 million for the year ended December 31, 2006 compared to the prior year. The increase in underwriting expenses was primarily due to higher incentive costs for agents and employees, and higher compensation expenses recognized under SFAS No. 123(R), which was adopted as of January 1, 2006, partially offset by lower pension costs and lower severance charges. Severance charges of $1.2 million and $3.5 million were incurred in 2006 and 2005, respectively, related to ongoing expense-reduction initiatives.

Harleysville Group froze its defined benefit pension plan at the then current benefit levels as of March 31, 2006. Harleysville Group’s portion of pension expense for the plan was $1.9 million and $9.7 million for 2006 and 2005, respectively. Harleysville Group enhanced its 401(k) retirement savings plan to provide for a company contribution equal to 5% of salary for all eligible employees, effective April 1, 2006, and recognized expense of $2.9 million in 2006 due to this enhancement.

Other income increased $1.2 million for the year ended December 31, 2006 primarily due to an increase of $1.7 million in claim handling fees received in connection with the National Flood Insurance Program, related primarily to flood claims from Hurricane Katrina.

New Accounting Standards

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” This statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. This statement applies under other accounting pronouncements that require or permit fair value measurements. The statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. The impact of adopting this statement on Harleysville Group’s results of operations and financial condition is not expected to be material.

entities with available for sale and trading securities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. The impact of adopting this statement on Harleysville Group’s results of operations and financial condition is not expected to be material.

Liquidity and Capital Resources

Liquidity is a measure of the ability to generate sufficient cash to meet cash obligations as they come due. Harleysville Group’s primary sources of cash are premium income, investment income and maturing investments. Cash outflows can be variable because of uncertainties regarding settlement dates for liabilities for unpaid losses and because of the potential for large losses, either individually or in the aggregate. Accordingly, Harleysville Group maintains investment and reinsurance programs generally intended to provide adequate funds to pay claims without forced sales of investments. Harleysville Group models its exposure to catastrophes and has the ability to pay claims without selling held to maturity securities even for events having a low (less than 1%) probability. Even in years of greater catastrophe frequency, Harleysville Group has been able to pay claims without liquidating any investments. Harleysville Group has also considered scenarios of declines in revenue and increases in loss payments, and has the ability to meet cash requirements under such scenarios without selling held to maturity securities. Harleysville Group’s policy with respect to fixed maturity investments is to purchase only those that are of investment grade quality.

Net cash provided by operating activities was $171.5 million and $166.1 million for 2007 and 2006, respectively. The increase in net cash provided by operating activities during 2007 is primarily from greater investment income and lower federal income tax payments, partially offset by a decrease in net cash provided by underwriting activities.

Net cash used by investing activities was $92.7 million and $168.8 million for 2007 and 2006, respectively. The change is primarily due to lower net purchases of investments due to the increase in cash used by financing activities.

Financing activities used net cash of $78.7 million and provided net cash of $2.5 million for 2007 and 2006, respectively. The change is primarily due to the purchase of treasury stock in 2007, a decrease in the issuance of common stock and an increase in dividends paid.

Harleysville Group’s investment strategy is designed to complement and support the insurance operations. Harleysville Group considers projected cash flow (premiums, investment income, reinsurance programs, liability payout patterns, general expenses, large seasonal obligations, intercompany transfers, etc.) to assure that sufficient liquidity exists within Harleysville Group and the Mutual Company. Maintaining a regular maturity schedule in readily marketable securities is an essential part of addressing liquidity. This regular maturity schedule is maintained in all interest rate environments. After-tax yield will be maximized consistent with safety and liquidity considerations by investment in taxable or tax-exempt securities, depending on Harleysville Group’s tax position.

Harleysville Group participates in a securities lending program whereby certain fixed maturity securities from the investment portfolio are loaned to other institutions for a short period of time in return for a fee. At December 31, 2007, Harleysville Group had received, and had the obligation to return, cash collateral of $123.5 million. The cash collateral received was invested, as described below, in investments with a fair value at December 31, 2007 of $122.1 million, related to securities on loan with a fair value of $120.6 million. Harleysville Group’s policy is to require initial collateral of 102% of the fair value of loaned securities plus accrued interest, which is required to be maintained daily by the borrower at no less than 100% of such fair value plus accrued interest over the life of the loan. Cash collateral received can be further invested in money market instruments, government se curities, “A” rated corporate obligations, “AAA” rated asset-backed securities or GICs and Funding Agreements from issuers rated “A” or better. The cash collateral Harleysville Group received was invested as follows at December 31, 2007: 52% of the collateral was held in cash and cash equivalents (maturities of three months or less) and 48% of the collateral was held in securities which may fluctuate in value and have variable interest rates and maturities of up to three years. These securities are classified as available for sale. The securities on loan to others have been segregated from the other invested assets on the balance sheet. In addition, the assets and liabilities have been grossed up to reflect the investment of the collateral received under the securities lending program and the obligation to return this collateral upon the return of the loaned securities.

At December 31, 2007, Harleysville Group held the following fixed maturity investments in its securities lending collateral portfolio:

The fixed maturity investments in the SIVs consist predominantly of asset-backed and mortgaged-backed securities. Each of the SIVs listed above represents a senior claim on the assets of the issuer. The Cheyne and Stanfield Victoria holdings are in technical default and are currently under the supervision of receivers appointed to protect the interests of senior creditors. In the fourth quarter of 2007, an impairment loss of $0.8 million was recognized on the Cheyne holding due to a significant deterioration in the credit worthiness of the issuer.

Due to illiquid market conditions and deteriorating fundamentals in the housing industry, the value of some of the underlying assets that secure our position as a senior creditor in the SIVs is uncertain at this time. Depending upon developments involving the performance of the assets held by the SIVs, it is possible that the SIV holdings listed above may be written down in the income statement in the future.

Subsequent to December 31, 2007, the Atlas Capital Funding Corp. Medium Term Note was converted into a Wachovia Bank Certificate of Deposit with the same maturity date. In February 2008, we divested both of our Liquid Funding LTD Medium Term Notes maturing on November 4, 2008 and September 29, 2008 for losses of $15,000 and $10,000, respectively.

One of the holdings within the security lending portfolio, with an unrealized loss of $18,000 at December 31, 2007, has had an unrealized loss for over twelve months.

The Company had $4.0 million of cash and marketable securities at December 31, 2007, which are available for general corporate purposes including dividends, debt service, capital contributions to subsidiaries, acquisitions and the repurchase of stock. In June 2007, the Company’s Board of Directors authorized a stock repurchase plan under which up to 1.6 million shares of its outstanding common stock could be repurchased through an open market purchase program. The Company was authorized to repurchase shares from the Mutual Company, which owns 53% of the Company’s stock, at fair market value terms on the date of purchase and from the public float to amounts that are proportional to the respective ownership percentages of the Mutual Company and the public float as of the authorization date. This program was completed on July 18, 2007. On August 1, 2007, the Boa rd of Directors authorized the Company to repurchase an additional 1.6 million shares of its outstanding common stock for a two year period under terms similar to the first repurchase authorization. As of December 31, 2007, the Company had repurchased 335,439 shares under the second authorization, leaving 1,264,561 shares authorized to be repurchased. An additional 346,807 shares were repurchased through March 5, 2008. Harleysville Group has no other material commitments for capital expenditures as of December 31, 2007.

As a holding company, the Company’s principal source of cash for the payment of dividends is dividends from its insurance subsidiaries. The Company’s insurance subsidiaries are subject to state laws that restrict their ability to pay dividends. The Company’s insurance subsidiaries declared dividends payable to the Company of $117.6 million in June 2007. As of December 31, 2007 dividends of $63.0 million had been paid to the Company.

Applying the current regulatory restrictions as of December 31, 2007, $112.2 million would be available for distribution to the Company by its subsidiaries after June 5, 2008 without prior regulatory approval. See the Business-Regulation section of this Form 10-K, which includes a reconciliation of net income and shareholders’ equity as determined under statutory accounting practices to net income and shareholders’ equity as determined in accordance with accounting principles generally accepted in the United States of America. Also, see Note 8 of the Notes to Consolidated Financial Statements.

On August 18, 2006, Harleysville Group Inc. entered into a credit agreement with HSBC Bank USA, National Association, as Administrative Agent, and participating lenders relating to a five year $100 million revolving credit facility. At Harleysville Group Inc.’s election, interest will be calculated at the LIBOR Rate plus a Margin (currently 0.750% based on the credit rating of the Company’s debt) or the Alternate Base Rate (the greater of the Prime Rate or the Federal Funds Effective Rate plus 1/2 of 1%). In addition, there is a fee of 0.150% per annum on the loan commitment amount, regardless of usage. The agreement requires compliance with certain covenants, which include minimum net worth and leverage and fixed charge coverage ratios. The credit facility was available for general corporate purposes. There have been no borrowings under the credit facility. The Company was in compliance with all applica ble covenants. Effective January 8, 2008, the Company terminated this credit agreement because the Company felt it was no longer needed.

The National Association of Insurance Commissioners (NAIC) adopted risk-based capital (RBC) standards that require insurance companies to calculate and report statutory capital and surplus needs based on a formula measuring underwriting, investment and other business risks inherent in an individual company’s operations. These RBC standards have not affected the operations of Harleysville Group since each of the Company’s insurance subsidiaries has statutory capital and surplus in excess of RBC requirements.

These RBC standards require the calculation of a ratio of total adjusted capital to Authorized Control Level. Insurers with a ratio below 200% are subject to different levels of regulatory intervention and action. Based upon their 2007 statutory financial statements, the ratio of total adjusted capital to the Authorized Control Level for the Company’s eight insurance subsidiaries at December 31, 2007 ranged from 543% to 677%.

The following summarizes Harleysville Group’s contractual obligations at December 31, 2007.


	Total		Less Than 1 Year		1-3 Years		4-5 Years		After 5 Years
	(in thousands)
Contractual obligations:
Debt	$	118,500					$	18,500	$	100,000
Interest on debt	$	36,763	$	6,800	$	13,600	$	12,769	$	3,594
Gross liability for unpaid losses and loss settlement expenses	$	1,546,690	$	371,300	$	433,043	$	201,052	$	541,295
Total	$	1,701,953	$	378,100	$	446,643	$	232,321	$	644,889

The table above does not include capital lease obligations, operating lease obligations or purchase obligations as they are either not applicable or not material. The timing of the amounts for the gross liability for unpaid losses and loss settlement expenses is an estimate based on historical experience and expectations of future payment patterns. However, the timing of these payments may vary significantly from the amounts stated above.

Property and casualty insurance premiums are established before the amount of losses and loss settlement expenses, or the extent to which inflation may affect such expenses, are known. Consequently, Harleysville Group attempts, in establishing rates, to anticipate the potential impact of inflation. In the past, inflation has contributed to increased losses and loss settlement expenses.

Risk Factors

You should consider carefully the following risks, as well as the other information contained in this 2007 Report on Form 10-K. If any of the following events described in the risk factors below actually occur, our business, financial condition and results of operations could be adversely affected. You should refer to the other information set forth in this 2007 Report on Form 10-K including our consolidated financial statements and the related notes.

Risks Related to the Property and Casualty Insurance Industry Generally

If our estimated liability for losses and loss settlement expenses is incorrect, our reserves may not be adequate to cover our ultimate liability for losses and loss settlement expenses and may have to be increased.

We are required to maintain loss reserves for our estimated liability for losses and loss settlement expenses associated with reported and unreported claims for each accounting period. We regularly review our reserving techniques and our overall amount of reserves and, based on our estimated liability, raise or lower the levels of our reserves accordingly. If our estimates are incorrect and our reserves are inadequate, we are obligated to increase our reserves. An increase in reserves results in an increase in losses and a reduction in our net income for the period in which the deficiency in reserves is identified. Accordingly, an increase in reserves could have a material adverse effect on our results of operations, liquidity and financial condition. Our reserve amounts are estimated based on what we expect our ultimate liability for losses and loss settlement expenses to be. These estimates are based on facts and circumstances of which we are aware, predictions of future events, trends in claims severity and frequency and other subjective factors. Although we use a number of actuarial methods to project our ultimate liability, there is no method that can always exactly predict our ultimate liability for losses and loss settlement expenses.

In addition to reviewing our reserving techniques, as part of our reserving process we also consider:

information regarding each claim for losses;

our loss history and the industry’s loss history;

legislative enactments, judicial decisions and legal developments regarding damages;

changes in political attitudes; and

trends in general economic conditions, including inflation.

If certain catastrophic events occur, they could have a significant impact on our operational results and financial condition.

Results of property insurers are subject to weather and other events prevailing in any given year. While one year may be relatively free of major weather or other disasters, another year may have numerous such events causing results for that year to be materially worse than for other years.

Our insurance subsidiaries have experienced, and are expected in the future to experience, catastrophe losses. It is possible that a catastrophic event or a series of multiple catastrophic events could have a material adverse effect on the operating results and financial condition of our insurance subsidiaries, thereby limiting the ability of our insurance subsidiaries to pay dividends to us. In the last 9 years, the largest non-flood catastrophe to affect our results of operations was Hurricane Floyd in the third quarter of 1999, which resulted in $15.1 million of losses.

Various events can cause catastrophes, including severe winter weather, hurricanes, windstorms, earthquakes, hail, war, terrorism, explosions and fires. The frequency and severity of these catastrophes are inherently unpredictable. The extent of losses from a catastrophe is a function of both the total amount of insured exposures in the area affected by the event and the severity of the event.

Our insurance subsidiaries seek to reduce the impact on our business of a catastrophe through geographic diversification and through the purchase of reinsurance covering various categories of catastrophes, which generally excludes terrorism. Nevertheless, reinsurance may prove inadequate if

a major catastrophic loss exceeds the reinsurance limit or

an insurance subsidiary pays a number of smaller catastrophic loss claims that, individually, fall below the subsidiary’s retention level.

We are heavily regulated in the states in which we operate and if we violate those regulations or if the regulations unreasonably restrict our ability to do business, or if they change significantly, it could have an adverse effect on our business.

We are subject to extensive supervision and regulation in the states in which we transact business. The purpose of supervision and regulation is to protect individual policyholders and not shareholders or other investors. Our business can be adversely affected by private passenger automobile insurance regulations and any other regulations affecting property and casualty insurance companies. For example, laws and regulations can reduce or set rates at levels that we do not believe are adequate for the risks we insure. Other laws and regulations can limit our ability to cancel or refuse to renew policies and require us to offer coverage to all consumers. Changes in laws and regulations, or their interpretations, pertaining to insurance, including workers compensation, may also have an adverse effect on our business. Although the federal government does not directly regulate the insurance industry, federal initiatives, such as fede ral terrorism backstop legislation, from time to time, also can impact the insurance industry.

In addition, proposals intended to control the cost and availability of health care services have been debated in the U.S. Congress and state legislatures. Although we do not write health insurance, rules affecting health care services can affect other insurance that we write, including workers compensation and commercial and personal automobile and liability insurance. We cannot determine whether or in what form health care reform legislation may be adopted by the U.S. Congress or any state legislature. We also cannot determine the nature and effect, if any, that the adoption of health care legislation or regulations, or changing interpretations, at the federal or state level would have on us.

If demand for property and casualty insurance decreases, it could have an adverse impact on our business.

Historically, the results of the property and casualty insurance industry have been subject to significant fluctuations over time due to competition and due to unpredictable developments, including:

natural and man-made disasters;

fluctuations in interest rates and other changes in the investment environment that affect returns on our investments;

inflationary pressures that affect the size of losses; and

legislative and regulatory changes and judicial decisions that affect insurers’ liabilities.

The demand for property and casualty insurance, particularly commercial lines, also can vary with the overall level of economic activity.

If we are unable to reduce our exposure to risks through reliable reinsurance or if the cost of reinsurance increases, our risk of loss, or the cost of controlling our risk of loss, will increase.

We transfer a portion of our exposure to selected risks to other insurance and reinsurance companies through reinsurance arrangements. Under our reinsurance arrangements, another insurer assumes a specified portion of our losses and loss adjustment expenses in exchange for a specified portion of policy premiums. The availability, amount and cost of reinsurance depend on market conditions and may vary significantly. Any decrease in the amount of our reinsurance will increase our risk of loss. Furthermore, we face a credit risk when we obtain reinsurance because we are still liable for the transferred risks if the reinsurer cannot meet the transferred obligations. Therefore, the inability of any of our reinsurers to meet its financial obligations could materially and adversely affect our operations.

The threat of terrorism and military and other actions may result in decreases in our net income, revenue and assets under management and may adversely affect our investment portfolio.

The threat of terrorism, both within the United States and abroad, and military and other actions and heightened security measures in response to these types of threats, may cause significant volatility and declines in the equity markets in the United States, Europe and elsewhere, as well as loss of life, property damage, additional disruptions to commerce and reduced economic activity. Actual terrorist attacks could cause losses from insurance claims related to the property and casualty insurance operations of Harleysville Group, as well as a decrease in our stockholders’ equity, net income and/or revenue. The effects of changes related to Harleysville Group may result in a decrease in our stock price. The Terrorism Risk Insurance Act of 2002, which was originally extended in 2005 and extended again in 2007, requires that some coverage for terrorist loss be offered by primary property insurers and provides Federal assistan ce for recovery of claims through 2014. In addition, some of the assets in our investment portfolio may be adversely affected by declines in the equity markets and economic activity caused by the continued threat of terrorism, ongoing military and other actions and heightened security measures.

We cannot predict at this time whether and the extent to which industry sectors in which we maintain investments may suffer losses as a result of potential decreased commercial and economic activity, or how any such decrease might impact the ability of companies within the affected industry sectors to pay interest or principal on their securities, or how the value of any underlying collateral might be affected.

We can offer no assurances that the threats of future terrorist-like events in the United States and abroad or military actions by the United States will not have a material adverse effect on our business, financial condition or results of operations.

Certain changes in the accounting standards issued by the Financial Accounting Standards Board or other standard-setting bodies could have a material adverse impact on our reported net income.

We are subject to the application of U.S. GAAP and other accounting standards, which are periodically revised and/or expanded. As such, we are required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the Financial Accounting Standards Board. It is possible that future changes required to be adopted could change the current accounting treatment that we apply and such changes could result in material adverse impacts on our results of operations and financial condition.

If our investments, including our securities lending collateral, lose value, our revenues, earnings and financial position will be adversely affected.

Like many other property and casualty insurance companies, we depend on income from our investment portfolio for a significant portion of our revenues and earnings. Any significant decline in our investment income as a result of falling interest rates, decreased dividend payment rates or general market conditions would have an adverse effect on our results. Any significant decline in the market value of our investments, including the investments in our securities lending collateral portfolio, would reduce our shareholders’ equity and our policyholders’ surplus, which could impact our ability to write additional business.

If our financial strength ratings are reduced, we may be adversely impacted.

Insurance companies are subject to financial strength ratings produced by external rating agencies. Higher ratings generally indicate greater financial stability and a stronger ability to pay claims. Ratings are assigned by rating agencies to insurers based upon factors that they believe are relevant to policyholders. Ratings are not recommendations to buy, hold or sell our securities.

Although other agencies cover the property and casualty industry, we believe our ability to write business is most influenced by our rating from A. M. Best. According to A. M. Best, its ratings are designed to assess an insurer’s financial strength and ability to meet ongoing policyholder obligations. Currently, our rating from A. M. Best is “A-”, the 4th of A. M. Best’s 16 ratings. A rating below “A-” from A. M. Best could materially adversely affect the business we write. We believe that our financial strength rating from Moody’s (which is A3, the 7th of Moody’s 21 ratings), although important, has less of an impact on our business. An unfavorable change in our Moody’s financial strength rating, however, could make it more expensive for us to access capital markets. We cannot be sure that we will maintain our current A. M. Best or Moody’s ratings. Although Standard & Poor&# 146;s rates our debt securities at BBB-/Stable (the 10th of Standard & Poor’s 23 ratings), Standard & Poor’s does not currently rate our financial strength and ability to meet ongoing obligations.

Risks Related to Our Company in Particular

We face significant competition from other regional and national insurance companies, agents and from self-insurance, which may result in lower revenues.

We compete with local, regional and national insurance companies, including direct writers of insurance coverage. Many of these competitors are larger than we are and many have greater financial, technical and operating resources. In addition, we face competition within each insurance agency that sells our insurance because we sell through independent agencies that represent more than one insurance company.

The property and casualty insurance industry is highly competitive on the basis of product, price and service. If our competitors offer products with more coverage, or price their products more aggressively, our ability to grow or renew our business may be adversely impacted. There are more than 250 groups writing property and casualty insurance in the United States, and we are approximately 60th in size. Our most significant competitors vary significantly in our different lines of business and in the geographic markets in which we compete. The internet also could emerge as a significant source of new competition, both from existing competitors using their brand name and resources to write business through this distribution channel and from new competitors.

We also face competition because of entities that self-insure, primarily in the commercial insurance market. From time to time, certain of our customers and potential customers may examine the benefits and risks of self-insurance and other alternatives to traditional insurance.

A number of new, proposed or potential legislative or industry developments could further increase competition in the property and casualty insurance industry. These developments include:

the enactment of the Gramm-Leach-Bliley Act of 1999, which could result in increased competition from new entrants to the insurance market, including banks and other financial service companies;

programs in which state-sponsored entities provide property insurance in catastrophe-prone areas or other alternative market types of coverage; and

changing practices caused by the internet, which have led to greater competition in the insurance business and, in some cases, greater expectations for customer service.

New competition from these developments could cause the supply or demand for insurance to change, which could adversely affect our results of operations and financial condition.

If adverse conditions in the eastern and midwestern United States exist, our business would be disproportionately impacted.

We write property and casualty insurance business in the eastern and midwestern United States. Consequently, unusually severe storms or other natural or man-made disasters that destroy property in these states could adversely affect our operations. Our revenues and profitability also are subject to prevailing economic and regulatory conditions in the states in which we write insurance. We may be exposed to risks of adverse developments that are greater than if we conducted business nationwide.

We depend on independent insurance agents, which exposes us to risks not applicable to companies with dedicated agents.

We market and sell our insurance products through independent, non-exclusive insurance agencies. These agencies are not obligated to sell our insurance products, and generally they also sell our competitors’ insurance products. As a result, our business depends in part on the marketing and sales efforts of these agencies. If we diversify and expand our business geographically, then we may need to expand our network of agencies to successfully market our products. If these agencies fail to market our products successfully, our business may be adversely impacted. Also, independent agents may decide to sell their businesses to banks, other insurance agencies or other businesses. Changes in ownership of agencies, or expansion of agencies through acquisition, could adversely affect an agency’s ability to control growth and profitability, thereby adversely affecting our business.

If our insurance subsidiaries are not able to pay adequate dividends to us, our ability to meet our obligations and pay dividends would be affected.

Our principal assets are the shares of capital stock of our insurance company subsidiaries. We principally rely on dividends from our insurance company subsidiaries to meet our obligations for paying principal and interest on outstanding debt obligations and for paying corporate expenses and dividends to shareholders. As described below, the payment of dividends by our insurance company subsidiaries is subject to regulatory restrictions and will depend on the surplus and future earnings of these subsidiaries, as well as other regulatory restrictions. As a result, we may not be able to receive dividends from these subsidiaries at times and in amounts necessary to meet our obligations or to allow us to pay dividends.

Generally, the maximum dividend that may be paid by an insurance subsidiary during any year without prior regulatory approval is limited to a stated percentage of that subsidiary’s statutory surplus as of a certain date, or adjusted net income of the subsidiary for the preceding year. Our insurance subsidiaries paid dividends to us of $63.0 million in 2007 and $15.0 million in 2005. No dividends were paid in 2006. Applying the current regulatory restrictions as of December 31, 2007, $112.2 million would be available for distribution to us without prior approval after June 5, 2008. We anticipate no objections to the payment of the dividends described in the preceding sentence.

Notwithstanding the foregoing, if insurance regulators otherwise determine that payment of a dividend to an affiliate would be detrimental to an insurance subsidiary’s policyholders or creditors, because of the financial condition of the insurance subsidiary or otherwise, the regulators may block dividends to affiliates that would otherwise be permitted without prior approval.

Our subsidiaries are permitted under the terms of our indebtedness to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by our subsidiaries to us. We cannot assure you that the agreements governing the current and future indebtedness of our subsidiaries will permit our subsidiaries to provide us with sufficient dividends, distributions or loans to fund payments on these notes when due.

Although we have paid cash dividends in the past, we may not be able to pay cash dividends in the future.

We have a history of paying dividends to our shareholders when sufficient cash is available. However, future cash dividends will depend upon our results of operations, financial condition, cash requirements and other factors, including the ability of our subsidiaries to make distributions to us, which ability is restricted in the manner previously discussed in this section. Also, there can be no assurance that we will continue to pay dividends even if the necessary financial conditions are met and if sufficient cash is available for distribution.

If our technology initiatives are not successful, or the benefits are not realized, our business could be adversely affected.

Our businesses are increasingly dependent on technology. Our inability to anticipate or manage problems with technology, or fully realize the expected benefits from investments in technology, could adversely affect our ability to write business, and could adversely impact our financial results.

If we lose our key personnel our business could be adversely affected.

The success of our business is dependent, to a large extent, on our ability to attract and retain key employees, in particular our senior officers, and key management, sales, information systems, underwriting, claims and corporate personnel. Competition to attract and retain key personnel is intense. Although we have change of control agreements with a number of key managers, in general, we do not have employment contracts or non-compete arrangements with, or key person insurance covering, our employees, including our key employees.

Applicable insurance laws and certain provisions in our certificate of incorporation make it difficult to effect a change of control of our Company, and the Mutual Company has significant influence over potential change of control transactions, which could affect our share value.

Under applicable insurance laws and regulations of the states in which our subsidiaries are domiciled, no person may acquire control of us unless that person has filed a statement containing specified information with the insurance commissioner of each state and obtains advance approval for such acquisition. Under applicable laws and regulations, any person acquiring, directly or indirectly (by revocable proxy or otherwise), 10% or more of the voting stock of any other person is presumed to have acquired control of such person, and a person who beneficially acquires 10% or more of our common stock without obtaining advance approval of the insurance commissioner of each state would be in violation of applicable insurance laws and would be subject to injunctive action requiring disposition or seizure of the shares and prohibiting the voting of such shares, as well as other action determined by the insurance commissioner of each su ch state.

In addition, many state insurance laws require prior notification to the state insurance department of a change of control of a non-domiciliary insurance company licensed to transact an insurance business in that state. Although these pre-notification statutes do not authorize the state insurance departments to disapprove the change of control, they authorize regulatory action – including a possible revocation of our authority to do business – in the affected state if particular conditions exist such as undue market concentration. Any future transactions that would constitute a change of control of us may require prior notification in the states that have pre-acquisition notification laws.

As of December 31, 2007, the Mutual Company owned approximately 53% of our outstanding common stock. The Mutual Company’s stock ownership and ability, by reason of such ownership, to elect our board of directors, provides it with significant influence over potential change of control transactions. Section 203 of the Delaware General Corporation Law provides, however, that if a person acquires 15% or more of our voting stock, the person is an “interested stockholder” and may not engage in “business combinations” with us for a period of three years from the time the person acquired 15% or more of our voting stock, subject to certain exceptions.

Finally, our certificate of incorporation permits our board of directors to issue up to one million shares of preferred stock having such terms, including voting rights, as the board of directors shall fix and determine.

Equity Price Risk

Harleysville Group’s portfolio of equity securities, which is carried on the balance sheet at fair value, has exposure to price risk. Price risk is defined as the potential loss in fair value resulting from an adverse change in prices. Portfolio characteristics are analyzed regularly and price risk is actively managed through a variety of techniques.

The combined total of realized and unrealized equity investment gains was $3.5 million, $8.6 million and $1.2 million in 2007, 2006 and 2005, respectively. During these three years, the largest total equity investment gain and (loss) in a quarter was $7.0 million (1st quarter 2006) and $(5.8) million (2nd quarter 2006), respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1 - Description of Business and Summary of Significant Accounting Policies

Description of Business

Harleysville Group consists of Harleysville Group Inc. and its subsidiaries (all wholly owned). Those subsidiaries are:

Harleysville-Atlantic Insurance Company (Atlantic)

Harleysville Insurance Company (HIC)

Harleysville Insurance Company of New Jersey (HNJ)

Harleysville Insurance Company of New York (HIC New York)

Harleysville Insurance Company of Ohio (HIC Ohio)

Harleysville Preferred Insurance Company (Preferred)

Harleysville Worcester Insurance Company (Worcester)

Mid-America Insurance Company (Mid-America) - merged into Worcester in 2007

Harleysville Ltd., a real estate partnership that owns the home office

Harleysville Group is approximately 53% owned by Harleysville Mutual Insurance Company (Mutual).

Principles of Consolidation and Basis of Presentation

The accompanying financial statements include the accounts of Harleysville Group prepared in conformity with U.S. generally accepted accounting principles, which differ in some respects from those followed in reports to insurance regulatory authorities. All significant intercompany balances and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including loss and loss settlement expenses, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses, including the determination of other-than-temporary declines in investments, during the reporting period. Actual results could differ from these estimates.

Investments

Accounting for fixed maturities depends on their classification as held to maturity, available for sale or trading. Fixed maturities classified as held to maturity are carried at amortized cost. Fixed maturities classified as available for sale are carried at fair value. There were no investments classified as trading. Equity securities are carried at fair value. Short-term investments are recorded at cost, which approximates fair value. The fair value of fixed maturities is based upon data supplied by an independent pricing service. The fair value of equity securities is based on the closing market value. The fair value of mutual fund holdings is based on the closing net asset value reported by the fund.

Premiums and discounts on fixed income securities are amortized or accreted using the interest method. Mortgage-backed securities are amortized over a period based on estimated future principal payments, including prepayments. Prepayment assumptions are reviewed periodically and adjusted as necessary to reflect actual prepayments and changes in expectations. Adjustments related to changes in prepayment assumptions are recognized on a retrospective basis.

Realized gains and losses on sales of investments are recognized in net income on the specific identification basis. A decline in the fair value of an investment below its cost that is deemed other than temporary is charged to earnings. Unrealized investment gains or losses on investments carried at fair value, net of applicable income taxes, are reflected directly in shareholders’ equity as a component of comprehensive income and, accordingly, have no effect on net income. However, if the fair value of an investment declines below its cost and that decline is deemed other than temporary, the amount of the decline below cost is charged to earnings. Harleysville Group monitors its investment portfolio and at least quarterly reviews investments that have experienced a decline in fair value below cost to evaluate whether the decline is other than temporary. Such evaluations consider, among other things, the magnitude and reason s for a decline, the prospects for the fair value to recover in the near term and Harleysville Group’s ability and intent to retain the investment for a period of time sufficient to allow for a recovery in value.

Premiums

Premiums are recognized as revenue ratably over the terms of the respective policies. Unearned premiums are calculated on a pro rata basis.

Policy Acquisition Costs

Policy acquisition costs, such as commissions, premium taxes and certain other underwriting and agency expenses that vary with, and are primarily related to, the production of business, are deferred and amortized over the effective period of the related insurance policies in proportion to the premiums earned. The method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. The estimation of net realizable value takes into account the premium to be earned, related investment income over the claims paying period, expected losses and loss settlement expenses, and certain other costs expected to be incurred as the premium is earned. Future changes in estimates, the most significant of which is expected losses and loss settlement expenses, may require adjustments to deferred policy acquisition costs. If the estimation of net realizable value indicates tha t the acquisition costs are unrecoverable, further analyses are completed to determine if a reserve is required to provide for losses that may exceed the related unearned premiums.

Losses and Loss Settlement Expenses

The liability for losses and loss settlement expenses represents estimates of the ultimate unpaid cost of all losses incurred, which includes the gross liabilities to Harleysville Group’s policyholders plus the net liability to Mutual under the pooling agreement. See Note 2(a). Such estimates may be more or less than the amounts ultimately paid when the claims are settled. These estimates are periodically reviewed and adjusted as necessary; such adjustments are reflected in current operations.

Share-Based Payments

Harleysville Group has several share-based compensation plans. Harleysville Group had accounted for the plans under the provisions of Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. Accordingly, no compensation expense was recognized prior to 2006 for fixed stock option grants and an employee stock purchase plan. Effective January 1, 2006, Harleysville Group adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), “Share-Based Payment” (SFAS No. 123(R)), which replaced SFAS No. 123 and supercedes APB Opinion No. 25, using the modified prospective application provisions. SFAS No. 123(R) requires that the cost resulting from all share-based payment transactions be recognized in the financial statements.

Implementing SFAS No. 123(R) did not have a material effect on income before cumulative effect of accounting change and basic or diluted earnings per share before cumulative effect of accounting change in the year ended December 31, 2006. A cumulative effect of change in accounting benefit of $942,000, net of tax of $507,000, was recorded in the first quarter of 2006 related to the accounting for the Long Term Incentive Plan (LTIP). The LTIP has a cash component and a stock component which awards shares based on the total shareholder return of the Company’s stock relative to the total shareholder return of a group of insurance company stocks. Under APB Opinion No. 25, this plan had been accounted for using the intrinsic method. Under SFAS No. 123(R), the cash component is accounted for under the liability method and the stock component is accounted for as an equity instrument.

The following table illustrates the effect on net income and earnings per share as if the provisions of SFAS No. 123 (as amended by SFAS No. 148), “Accounting for Stock-Based Compensation,” had been applied to in 2005.


	2005
		(in thousands, except per share data)
Net income, as reported	$	61,431
Plus: Stock-based employee compensation expense included in reported net income, net of related tax effects		799
Less: Total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects		(2,934	)
Pro forma net income	$	59,296
Basic earnings per share:
As reported	$	2.02
Pro forma	$	1.95
Diluted earnings per share:
As reported	$	2.01
Pro forma	$	1.94

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is calculated primarily on the straight-line basis over the estimated useful lives of the assets (up to 40 years for buildings and three to 15 years for equipment).

Income Taxes

Deferred income tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

Earnings Per Share

Basic earnings per share is computed by dividing earnings by the weighted-average number of common shares outstanding during the year. Diluted earnings per share includes the dilutive effect of the stock incentive plans described in Note 10.

New Accounting Standards

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities--Including an amendment of FASB Statement No. 115.” SFAS No. 159 permits companies to choose to measure many financial instruments and certain other items at fair value at specified election dates. Upon adoption, an entity shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. Most of the provisions apply only to entities that elect the fair value option. However, the amendment to SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” applies to all entities with available for sale and trading securities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. The impact of adopt ing this statement on Harleysville Group’s results of operations and financial condition is not expected to be material.

2 - Transactions with Affiliates

(a) Underwriting

The insurance subsidiaries participate in a reinsurance pooling agreement with Mutual whereby such subsidiaries cede to Mutual all of their insurance business and assume from Mutual an amount equal to their participation in the pooling agreement. All losses and loss settlement expenses and other underwriting expenses are prorated among the parties on the basis of participation in the pooling agreement. The agreement pertains to all insurance business written or earned on or after January 1, 1986. Harleysville Group’s participation was 72% for 2007, 2006, and 2005.

Effective January 1, 2008, the Company’s property and casualty subsidiaries and Mutual and its property and casualty subsidiary, Harleysville Pennland Insurance Company (Pennland) amended their intercompany pooling agreement to increase Harleysville Group’s share of the pool from 72% to 80%. Harleysville Group received cash and investments of $192.1 million on January 3, 2008 associated with the transfer of assets and liabilities from the Mutual Company and Pennland to Harleysville Group in connection with the pool change.

Because this pooling agreement does not relieve Harleysville Group of primary liability as the originating insurer, there is a concentration of credit risk arising from business ceded to Mutual. However, the reinsurance pooling agreement provides for the right of offset, and the amount of credit risk with Mutual was not material at December 31, 2007 and 2006. Mutual has an A. M. Best rating of “A-” (Excellent).

The following amounts represent reinsurance transactions between Harleysville Group and Mutual under the pooling arrangement:


	2007		2006		2005
	(in thousands)
Ceded:
Premiums written	$	764,070	$	750,516	$	743,170
Premiums earned	$	753,806	$	742,752	$	740,273
Losses incurred	$	490,058	$	482,599	$	490,517
Assumed:
Premiums written	$	837,993	$	838,817	$	847,856
Premiums earned	$	833,024	$	838,821	$	850,379
Losses incurred	$	522,735	$	539,213	$	566,770
Net assumed from Mutual:
Unearned premiums	$	28,555	$	33,850	$	41,618
Unpaid losses and loss settlement expenses	$	149,826	$	178,327	$	187,293

Harleysville Group had a reinsurance agreement with Mutual whereby Mutual reinsured accumulated catastrophe losses in a quarter up to $14,400,000 in excess of $3,600,000 in return for a reinsurance premium. The agreement was terminated on December 31, 2005. The agreement excluded catastrophe losses resulting from earthquakes, terrorism or hurricanes, and supplemented the existing external catastrophe reinsurance program. Under this agreement, Harleysville Group ceded to Mutual no premiums earned for 2007 and 2006, and premiums earned of $8,812,000 for 2005. Losses incurred ceded to Mutual under the agreement were not material for any of the periods presented.

(b) Property

Harleysville Ltd. leases the home office to Mutual, which shares the facility with Harleysville Group. Rental income under the lease was $4,086,000, $4,051,000 and $3,961,000 for 2007, 2006, and 2005, respectively, and is included in other income after elimination of intercompany amounts of $2,501,000, $2,479,000 and $2,424,000 in 2007, 2006 and 2005, respectively.

(c) Management Agreements

Harleysville Group Inc. received $6,303,000, $6,420,000 and $6,697,000 of management fee income in 2007, 2006 and 2005, respectively, under agreements whereby Harleysville Group Inc. provides management services to Mutual and other affiliates. Such amounts are included in other income.

(d) Intercompany Balances

Intercompany balances are created primarily from the pooling arrangement (settled quarterly), allocation of common expenses, collection of premium balances and payment of claims (settled monthly). No interest is charged or received on intercompany balances due to the timely settlement terms and nature of the items. Interest expense on the loan from Mutual described in Note 7 was $1,057,000, $1,016,000 and $699,000 in 2007, 2006 and 2005, respectively.

Harleysville Group has off-balance-sheet credit risk related to approximately $78,000,000 and $77,000,000 of premium balances due to Mutual from agents and insureds at December 31, 2007 and 2006, respectively.

The fixed maturity investments with continuous unrealized losses for less than twelve months were primarily due to a widening of credit spreads rather than a decline in credit quality. There are $323.1 million in fixed maturity securities, at fair value, that at December 31, 2007, had been below amortized cost for over 12 months. The $4.4 million of unrealized losses on such securities primarily relates to securities which carry an investment grade debt rating and have declined in fair value roughly in line with market interest rate changes. Harleysville Group currently has the ability and intent to hold these securities until recovery.

Harleysville Group records the actuarial best estimate of the ultimate unpaid losses and loss settlement expenses incurred. Actuarial loss reserving techniques and assumptions, which rely on historical information as adjusted to reflect current conditions, have been consistently applied during the periods presented. Changes in the estimate of the liability for unpaid losses and loss settlement expenses reflect actual payments and evaluations of new information and data since the last reporting date. These changes correlate with actuarial trends.

In establishing the liability for unpaid losses and loss settlement expenses, management considers facts currently known and the current state of the law and coverage litigation. Liabilities are recognized for known losses (including the cost of related litigation) when sufficient information has been developed to indicate the involvement of a specific insurance policy, and management can reasonably estimate its liability. In addition, liabilities have been established to cover additional exposures on both known and unasserted losses. Estimates of the liabilities are reviewed and updated on a regular basis.

The property and casualty insurance industry has received significant publicity about environmental-related losses from exposures insured many years ago. Since the intercompany pooling agreement pertains to insurance business written or earned on or after January 1, 1986, Harleysville Group has not incurred significant environmental-related losses.

Total deferred tax assets		98,262		110,929
Net deferred tax asset	$	38,544	$	60,643

A valuation allowance is required to be established for any portion of the deferred tax asset that management believes will not be realized. In the opinion of management, it is more likely than not that the benefit of the deferred tax asset will be realized through the generation of future income. Therefore, no such valuation allowance has been established.

Effective January 1, 2007, Harleysville Group adopted FASB Interpretation (FIN) No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109.” As of January 1, 2007 and December 31, 2007, Harleysville Group had no material unrecognized tax benefits or accrued interest and penalties. The Company’s policy is to account for interest as a component of interest expense and penalties as a component of other expense. Federal tax years 2004 through 2007 were open for examination as of December 31, 2007.

In accordance with APB Opinion No. 25, the compensation expense that was charged against income before tax was $1,229,000 for 2005 with a corresponding income tax benefit of $430,000.

Fixed Stock Option Plans

Harleysville Group has an Equity Incentive Plan (EIP) for key employees. Awards may be made in the form of stock options, stock appreciation rights (SARs), restricted stock, restricted stock units or any combination of the above. The EIP was amended in 1997, 2006 and 2007 and limited future awards to an aggregate of 1,000,000 shares, plus the remaining shares under the 1997 plan, of Harleysville Group Inc.’s common stock. Such shares may be authorized and unissued shares or treasury shares. The plan provides that stock options may become exercisable from six months to 10 years from the date of grant with an exercise price not less than fair market value on the date of grant. Options granted prior to 2006 normally vest 50% at the end of one year and 50% at the end of two years from the date of grant. Options granted in 2006 and 2007 normally vest 33 1/3% at the end of one year, 33 1/3% at the end of two years and 33 1/3% at the end of three years from the date of grant. SARs have not been material. Restricted stock awards have vesting periods of three to five years and vest 100% at the end of the period. Restricted stock units have a vesting period of five years and vest 100% at the end of the period.

In determining the expense to be recorded for stock options, the fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. The significant assumptions utilized in applying the Black-Scholes option pricing model are the risk-free interest rate, expected term, dividend yield, and expected volatility. The risk-free interest rate is the implied yield currently available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term used as the assumption in the model. The expected term of an option award is based on historical experience of similar awards. The dividend yield is determined by dividing the per share- dividend by the grant date stock price. The expected volatility is based on the volatility of the Company’s stock price over a historical period comparable to the expected term. The weighted average assumptions used in applying the Black-Scho les valuation model are shown below:

As of December 31, 2007 the Company’s total unrecognized compensation cost related to nonvested share-based compensation arrangements (including share options, restricted stock and restricted stock unit awards) granted under the plan was $6,018,000. The cost is expected to be recognized over a weighted average period of 2.6 years.

Other Stock Purchase and Incentive Plans

Harleysville Group Inc. is authorized to issue up to 1,650,000 shares of common stock under the terms of the 1995 Employee Stock Purchase Plan as amended in 2003. Such shares may be authorized and unissued shares or treasury shares. Virtually all employees are eligible to participate in the plan, under which a participant may elect to have up to 15% of base pay withheld to purchase shares. The purchase price of the stock is 85% of the lower of the beginning-of-the-subscription-period or end-of-the-subscription-period fair market value. Subscription periods run from January 15 through July 14, or July 15 through January 14 in each year.

In determining the expense to be recorded for the employee stock purchase plan, the fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:


	Employee Stock Purchase Plan
	For the year ended December 31,
		2007	2006	2005
Risk-free interest rate		5.06%	4.84%	3.03%
Expected term		6 months	6 months	6 months
Dividend yield		2.23%	2.39%	3.05%
Expected volatility		18.34%	23.33%	30.59%

The weighted-average fair value of options granted under the employee stock purchase plan was $6.74, $6.11 and $4.90 for 2007, 2006 and 2005, respectively. The total intrinsic value of options exercised under the plan was $297,000, $581,000 and $471,000 for 2007, 2006 and 2005, respectively. Compensation expense of $281,000 and $336,000 related to grants under the plan was recognized in 2007 and 2006 respectively. As of December 31, 2007, there was $12,000 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the plan. The cost is expected to be recognized over a period of one month.

The 1996 Directors’ Stock Purchase Plan provided for the issuance of up to 200,000 shares of Harleysville Group Inc. common stock to outside directors of Harleysville Group Inc. and Mutual. The purchase price of the stock was 85% of the lower of the beginning-of-the-subscription-period or end-of-the-subscription-period fair market value. In 2005, there were 3,887 shares issued under the plan for which $23,000 of expense was recognized. This plan was discontinued and the last subscription period ended January 14, 2005.

The 2005 Non-Employee Directors’ Deferred Stock Unit Plan provided for the grant of up to 110,000 fully vested deferred stock units to outside directors of Harleysville Group Inc. and Mutual. Each stock unit represents the right to receive, without payment to the Company, one share of common stock of Harleysville Group Inc. The plan was amended and restated in 2007 to provide for the grant of awards in the form of stock options, deferred stock units and restricted stock and was renamed the Amended and Restated Directors’ Equity Compensation Plan. The aggregate number of shares which may be issued under the plan is 500,000, which may be either authorized and unissued shares or treasury shares. At each April Board of Directors meeting, each non-employee director shall receive a number of deferred stock units equal to the result of dividing $50,000 by the fair market value of a share of HGI common stock.

The expense to be recorded for the deferred stock units is determined utilizing the number of awards granted and the grant date fair market value. The expense is recognized at the date of grant as the awards are fully vested. In 2007, 2006 and 2005, respectively, there were 16,574, 10,050 and 13,500 units issued under the plan for which $454,000, $254,000 and $232,000 of expense was recognized. The weighted average grant date fair value of units granted during 2007, 2006 and 2005 was $32.08, $29.85 and $20.00 per unit, respectively.

The Long Term Incentive Plan (LTIP) provides for the issuance of up to 600,000 shares of Harleysville Group Inc. common stock, which may be authorized and unissued shares or treasury shares. Shares are awarded to key employees based on the total shareholder return of the Company’s stock relative to the total shareholder return of a group of insurance company stocks for a three year period. Current plans are in effect for the three year period January 1, 2005 through December 31, 2007. The fair value of the stock component of the plan was estimated on the date of grant using a 10,000 trial simulation with the following assumptions:


		Plan Years 2005-2007
Risk-free interest rate		3.63%
Expected volatility		37.2%
Target number of shares to be issued		68,592

The weighted-average grant date fair value of the 2005-2007 plan stock award was $19.64 per share. Compensation expense of $434,000, $823,000, and $832,000 was recognized related to the stock component of the LTIP for 2007, 2006 and 2005, respectively. As of December 31, 2007, there was no unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the LTIP. No shares were issued under the plan in 2006 and 2005. During 2007, 95,704 shares were issued in connection with plan years 2004-2006.

The LTIP also has a cash component. This component had been accounted for under the intrinsic method of APB Opinion No. 25 prior to January 1, 2006. It is now being accounted for under the liability method of SFAS No. 123(R). Compensation expense of $407,000, $616,000 and $250,000 was recognized related to the cash component of the LTIP for 2007, 2006 and 2005, respectively. As of December 31, 2007, there was no unrecognized compensation cost related to the cash component.

Cash received from option exercises under all share-based payment arrangements for 2007, 2006 and 2005 was $9,034,000, $20,050,000 and $5,101,000, respectively. The actual tax benefit realized for the tax deductions from option exercises of the share-based payment arrangements was $1,439,000, $3,281,000 and $557,828, respectively, for 2007, 2006 and 2005.

Harleysville Group has incentive bonus plans. The plans were amended in 2006 to include virtually all employees. Cash bonuses are earned on a formula basis depending upon the performance of Harleysville Group and Mutual in relation to certain targets. Harleysville Group’s expense for such plans was $5,920,000, $6,901,000 and $3,836,000 for 2007, 2006 and 2005, respectively.

11 - Pension and Other Benefit Plans

Harleysville Group Inc. has a frozen pension plan that covers employees hired before January 1, 2006. Retirement benefits are a function of both the years of service and level of compensation. Harleysville Group Inc.’s funding policy is to contribute annually an amount equal to at least the minimum required contribution in accordance with minimum funding standards established by ERISA. Contributions are intended to provide for benefits attributed to service through March 31, 2006. Harleysville Group Inc. uses a December 31, measurement date for the pension plan. The plan was frozen at the then current benefit levels as of March 31, 2006, at which time the accrual of future benefits for eligible employees ceased. The curtailment loss for the qualified plan has been reflected in the net periodic pension cost for 2005. The curtailment benefit for the supplemental executive retirement plan of $146,000 was re cognized in the first quarter of 2006.

The following table sets forth the year-end status of the plan including Mutual:

Weighted-average assumptions used to determine benefit obligations at December 31:
Discount rate		6.55	%		5.95	%		5.70	%
Rate of compensation increase - supplemental executive retirement plan		N/A			N/A			4.50	%
Weighted-average assumptions used to determine net cost for years ended December 31:
Discount rate		5.95	%		5.70	%		5.75	%
Expected return on plan assets		8.25	%		8.25	%		8.25	%
Rate of compensation increase - supplemental executive retirement plan through March 31, 2006		N/A			4.50	%		4.50	%

Amounts in accumulated other comprehensive income expected to be recognized as components of net periodic pension cost in 2008 are as follows: net actuarial loss $177,000.

The discount rate assumption used to determine the benefit obligation was based on high quality bond yields that relate to the estimated timing of benefit payouts of the plan.

Harleysville Group’s pension plan asset allocations at December 31, 2007 and 2006 are as follows:


	2007	2006
Asset Category:
Cash and cash equivalents	8%	4%
Equity securities	73%	74%
Debt securities	19%	22%
Total	100%	100%

The pension plan assets are managed to maximize total return over the long-term while providing sufficient liquidity and current return in order to satisfy the cash flow requirements of the plan. In order to meet these objectives, the target allocation for equity securities is a range of 65% to 75% of the market value of the fund’s portfolio and the target allocation for debt securities is a range of 25% to 35% of the market value of the fund’s portfolio.

To develop the expected long-term rate of return on assets assumption, the company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension plan portfolio. This resulted in the selection of the 8.25% long-term rate of return on assets assumption.

Cash Flows

The expected 2008 contribution to the pension plan is $3,409,000 of which $2,222,000 is Harleysville Group’s expected portion.

The following benefit payments, which reflect service through March 31, 2006, are expected to be paid:


	December 31,
	Total Plan		Harleysville Group’s Portion
2008	$	7,520,000	$	4,902,000
2009		7,839,000		5,110,000

2012		8,888,000		5,794,000
2013-2017		53,223,000		34,696,000

Harleysville Group has profit-sharing plans covering qualified employees. Harleysville Group’s expense under the plans was $4,264,000, $3,956,000 and $2,565,000 for 2007, 2006 and 2005, respectively. The plan was amended, effective April 1, 2006, to require a Company core contribution, equal to 5% of salary, to be automatically contributed to all eligible employees’ accounts on a biweekly basis regardless of the employees’ salary deferral amounts into the plan. Harleysville Group’s expense for the Company core contribution was $3,738,000 and $2,866,000 in 2007 and 2006, respectively.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of u nauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Harleysville Group Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established inInternal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Harleysville Group Inc. and Subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2007, and our report dated March 7, 2008 expressed an unqualified opinion on those consolidated financial statements.
