Rosenberg, Senior Assistant Chief Accountant Re: Harleysville Group Inc. Form 10-K for the fiscal year ended December 31, 2004 File No. 0-14697 ---------------- Ladies and Gentlemen: We are pleased to provide this response letter on behalf of Harleysville Group Inc. ("Registrant"). This letter is a follow-up to the telephone conversation between Registrant's representatives and the Staff on February 2, 2006, and the response letters dated January 6, 2006 and January 20, 2006 ("1/20 Response Letter"), filed by Registrant in response to the Staff's comment letter dated December 21, 2005, regarding the above captioned Form 10-K for the fiscal year ended December 31, 2004, filed by Registrant. Consistent with the above-referenced conversation, Registrant hereby amends and supplements its response to comments 2 through 5 of the Staff's comment letter provided by Registrant in the 1/20 Response Letter and advises the Staff that it will include the following disclosures prospectively, beginning with Registrant's Annual Report on Form 10-K for the year ended December 31, 2005 (the "2005 Form 10-K"). For your convenience, the substance of the Staff's oral comments with respect to Registrant's response to comments 2 through 5 have been reproduced below and are followed by Registrant's supplemental responses. United States Securities and Exchange Commission February 10, 2006 Page 2 Form 10-K for the fiscal year ended December 31, 2004 - ----------------------------------------------------- Item 7. Management's Discussion and Analysis of Financial Condition and , - --------------------------------------------------------------------------- page 21 ------- Critical Accounting Policies, page 22 - ------------------------------------- 2. The Staff advises Registrant that in future filings Registrant should provide the same information provided by Registrant in the 1/20 Response Letter with respect to unrealized losses on airline enhanced equipment trust certificates (EETCs), including a statement that Registrant intends to hold these securities until maturity. Further, the Staff advises that Registrant should clarify its inference that the collateral securing the airline EETCs is in excess of the security value. Supplemental Response: - --------------------- Registrant supplementally confirms that on the 2005 Form 10-K and in future filings, Registrant will provide disclosure consistent with the disclosure set forth in its response to comment 2 in the 1/20 Response Letter, including, a statement that Registrant has the ability and intends to continue to maintain holdings in the EETC investments until maturity. Further, as a supplement to Registrant's statement that Registrant considers the loan to collateral value to provide protection in the event of an adverse economic environment, Registrant provides the following additional disclosure: According to the most recent (August 2005) report provided to Registrant by JP Morgan, the market value of aircraft collateral underlying Registrant's EETC holdings exceeds Registrant's outstanding A Tranche cost and therefore provides additional security for such EETCs. The report was prepared by JP Morgan based on its own research on collateral values as well as research from Aviation Specialists Group. A recent transaction involving one of Registrant's EETCs is indicative of the current strength in the collateral value of the collateral underlying Registrant's EETCs. In that transaction, which was completed on February 6, 2006, holders of Subordinate B Tranche in the UAL 2000-1 EETC exercised their right to invoke a mandatory purchase of all outstanding A Tranche bonds with respect to the UAL 2000-1 EETCs at par value plus interest due and accrued. Registrant thereby recovered its investment in the UAL 2000-1 EETCs plus interest due and accrued. Liabilities and Loss Settlement Expenses, page 22 - ------------------------------------------------- 3. The Staff advises that Registrant should (a) provide the table provided in response to comment 3 in the 1/20 Response Letter in future filings, (b) clarify the disclosure made by Registrant in response to comment 3 in the 1/20 Response Letter with respect to prior disclosure by Registrant of a 1% change in estimated loss reserves, and (c) tie the loss reserve information set forth in the table provided by Registrant in response to comment 3 in the 1/20 Response Letter back to the loss reserve number on Registrant's balance sheet. United States Securities and Exchange Commission February 10, 2006 Page 3 Supplemental Response: - ---------------------- (a) Registrant supplementally confirms that on the 2005 Form 10-K and in future filings, Registrant will provide additional information on unpaid losses and loss settlement expenses net of reinsurance by line of business in tabular format consistent with the tabular disclosure set forth in item (c) below. (b) Registrant supplementally advises that Registrant believes that the 90% confidence interval produced through its statistical analysis reflects a reasonably likely effect on operations and financial position resulting from evaluations of new information and data since the last reporting date. On the 2005 Form 10-K and in future filings, Registrant will no longer cite the impact of a 1% change in estimated loss reserves and instead Registrant will provide a disclosure consistent with the disclosure set forth herein and in Registrant's response to comment 3 in the 1/20 Response Letter. (c) Below is a revised table which ties the loss reserve information reflected therein back to the loss reserve number reflected on Registrant's balance sheet.
