Reinsurance

Atlantic States and Donegal Mutual have participated in a pooling agreement since 1986 under which each company places all of its direct written premiums into the pool the pooling agreement established, and Atlantic States and Donegal Mutual then share the underwriting results of the pool in accordance with the terms of the pooling agreement. Atlantic States has an 80% share of the results of the pool, and Donegal Mutual has a 20% share of the results of the pool.

Our insurance subsidiaries and Donegal Mutual purchase certain third-party reinsurance on a combined basis. Le Mars, MICO, Peninsula and Sheboygan also purchase separate third-party reinsurance that provides coverage that we believe is commensurate with their relative size and risk exposures. Our insurance subsidiaries use several different reinsurers, all of which, consistent with the requirements of our insurance subsidiaries and Donegal Mutual, have an A.M. Best rating of A- (Excellent) or better or, with respect to foreign reinsurers, have a financial condition that, in the opinion of our management, is equivalent to a company with at least an A- rating from A.M. Best. The following information describes the external reinsurance our insurance subsidiaries have in place for 2017:

•

excess of loss reinsurance, under which Donegal Mutual and our insurance subsidiaries recover, through a series of reinsurance agreements, losses over a set retention (generally $1.0 million), and

•

catastrophe reinsurance, under which Donegal Mutual and our insurance subsidiaries recover, through a series of reinsurance agreements, 100% of an accumulation of many losses resulting from a single event, including natural disasters, over a set retention (generally $5.0 million) and after exceeding an annual aggregate deductible (generally $1.0 million) up to aggregate losses of $170.0 million per occurrence.

Our insurance subsidiaries and Donegal Mutual also purchase facultative reinsurance to cover exposures in excess of the covered limits of their third-party reinsurance agreements.

In addition to the pooling agreement and third-party reinsurance, our insurance subsidiaries have various reinsurance agreements with Donegal Mutual.

We have made no significant changes to our third-party reinsurance or the reinsurance agreements between our insurance subsidiaries and Donegal Mutual during the three months ended March 31, 2017.
