Reinsurance | ## 12. Reinsurance The Company utilizes reinsurance agreements to reduce its exposure to large claims and catastrophic loss occurrences and to increase its capacity to write profitable business. These agreements provide for recovery from reinsurers of a portion of losses and LAE under certain circumstances without relieving the insurer of its obligation to the policyholder. Losses and LAE incurred and premiums earned are reflected after deduction for reinsurance. In the event reinsurers are unable to meet their obligations under reinsurance agreements, the Company would not be able to realize the full value of the reinsurance recoverable balances. The Company periodically evaluates the financial condition of its reinsurers in order to minimize its exposure to significant losses from reinsurer insolvencies. Reinsurance does not discharge or diminish the primary liability of the Company; however, it does permit recovery of losses on such risks from the reinsurers. The Company has coverage for its workers’ compensation line of business under excess of loss reinsurance agreements. As the scale of the Company’s workers’ compensation business has increased, the Company has also increased the amount of risk retained. The agreements cover, per occurrence, losses in excess of $500 through December 31, 2004, $600 effective January 1, 2005, $1,000 effective July 1, 2006 through July 1, 2009, $1,000 plus 55% of $9,000 in excess of $1,000 effective July 1, 2009 through January 1, 2010, and $10,000 effective January 1, 2010 up to a maximum $130,000 ($50,000 prior to December 1, 2003) in losses. For losses occurring on or after January 1, 2010, the Company has purchased a “third and fourth event cover” that covers losses between $5,000 and $10,000 per occurrence, after a deductible equal to the first $10,000 per annum on such losses. For losses occurring on or after January 1, 2011, we replaced this “third and fourth event cover” with a “second and third event cover” that applies after an aggregate deductible equal to the first $5,000 per annum on such losses. Effective August 19, 2011, we purchased a new layer of coverage providing $100,000 in excess of $130,000 per occurrence, providing us with total protection of $220,000 for losses in excess of $10,000. The Company’s reinsurance for worker’s compensation losses caused by acts of terrorism is more limited than its reinsurance for other types of workers’ compensation losses and, through December 31, 2011, provided coverage, per contract year, of $220,000 in the aggregate in excess of an aggregate retention of $10,000, but excludes acts of nuclear, biological or chemical terrorism (which are covered by the Terrorism Risk Insurance Act, as amended). The Company has coverage for its U.S. casualty lines of business under an excess of loss reinsurance agreement. The agreement covers losses in excess of $2,000 per occurrence (in certain cases the retention can rise to $2,500) up to a maximum $30,000. The Company purchases quota share reinsurance for its non-program umbrella business, whereby we cede 70% of the first $5,000 of loss per policy and 100% of the next $5,000 loss per policy. In addition, we also purchase various pro-rata and excess reinsurance relating to specific insurance programs and/or specialty lines of business, including casualty, public entity, and professional errors and omissions insurance. The Company has coverage for its U.S. property lines of business under an excess of loss reinsurance agreement. The agreement covers losses in excess of $2,000 per location up to a maximum $20,000, subject to per occurrence and annual limits that vary by layer. In addition the Company has a property catastrophe excess of loss agreement, which covers losses in excess of $5,000 per occurrence up to a maximum $65,000, subject to annual limits that vary by layer. The Company has coverage for its U.K. property lines of business under an excess of loss reinsurance agreement. The agreement covers losses in excess of £500 per risk up to a maximum £2,000 per risk. In addition, the Company has a property catastrophe excess of loss agreement, which covers losses in excess of £5,000 per occurrence up to a maximum £45,000. The Company also has excess of loss reinsurance coverage for international general liability and non-medical professional business underwritten by our English and Irish insurers. The agreements cover losses in excess of £1,000 per occurrence up to a maximum of £10,000 per occurrence, subject to annual aggregate limits that vary by layer. Through December 31, 2010, we had excess of loss reinsurance under the same terms for our European medical liability business. In 2010, we purchased an 80% quota share reinsurance agreement from National Indemnity Company for our European medical liability business. This contract was effective for claims made through March 31, 2011. Effective April 1, 2011, we replaced this quota share reinsurance agreement with a 40% cession to Maiden Insurance, as more fully described below in Note 13 “Related Party Transactions.” In addition, we purchase various pro-rata and excess reinsurance relating to specific foreign insurance programs and/or specialty lines of business. TIC acts as servicing carrier on behalf of Workers’ Compensation Assigned Risk Plans in eight states. TIC issues and services certain workers compensation policies issued to assigned risk insureds. Those policies issued are subject to a 100% quota-share reinsurance agreement offered by the National Workers Compensation Reinsurance Pool or a state-based equivalent, which is administered by the National Council on Compensation Insurance, Inc. TIC, wrote approximately $46,000, $37,000 and $35,400 of premium in 2011, 2010 and 2009, respectively, as a servicing carrier. As part of the agreement to purchase WIC from Household Insurance Group Holding Company (“Household”), the Company agreed to write certain business on behalf of Household for a three-year period through June 2009. The premium written under this arrangement is 100% reinsured by HSBC Insurance Company of Delaware, a subsidiary of Household. The reinsurance recoverable associated with this business is guaranteed by Household. This business is now in run-off. WIC wrote approximately $7,300, $8,800 and $17,100 of premium in 2011, 2010 and 2009, respectively, subject to this reinsurance treaty. As part of its acquisition of AIIC, the Company acquired reinsurance recoverable as of the date of closing. The most significant reinsurance recoverable is from American Home Assurance Company (“American Home”). AIIC’s reinsurance relationship with American Home incepted January 1, 1998 on a loss occurring basis. From January 1, 1998 through March 31, 1999 the American Home reinsurance covered losses in excess of $250 per occurrence up to statutory coverage limits. Effective April 1, 1999, American Home provided coverage in the amount of $150 in excess of $100. This additional coverage terminated on December 31, 2001 on a run-off basis. Therefore, for losses occurring in 2002 that attached to a 2001 policy, the retention was $100 per occurrence. Effective January 1, 2002 American Home increased its attachment was $250 per occurrence. The XOL treaty that had an attachment of $250 was terminated on a run-off basis on December 31, 2002. Therefore, losses occurring in 2003 that attached to a 2002 policy were ceded to American Home at an attachment point of $250 per occurrence. As of December 31, 2011, the Company had $66,370 of reinsurance recoverables with American Home. During the third quarter of 2007, the Company entered into a master agreement with Maiden, as amended, by which its Bermuda subsidiary, AII, and Maiden Insurance entered into a quota share reinsurance agreement (the “Maiden Quota Share”). For a description of this agreement see Note 13. “Related Party Transactions.” The effect of reinsurance with unrelated companies on premiums and losses for 2011, 2010 and 2009 are as follows:

The Company continuously updates the reserves on these lines of business based on information available from the ceding insurers. During 2011, the Company had no commutations related to workers’ compensation that were included in ceded reinsurance treaties. During 2010, the Company commuted certain loss reserves of $1,350 related to workers’ compensation that were included in ceded reinsurance treaties. This commutation had no material effect on net earnings in either year.
