Note 3: Insurance Activity

The Company, through WMMRC, reinsures mortgage guaranty risks of mortgage loans originated by affiliates of the Company during the period from 1997 through 2008. WMMRC is (or was) a party to reinsurance agreements with UGRIC, GMIC, MGIC, PMI, Radian, RMIC and Triad. The agreements with UGRIC and Triad were placed into runoff effective May 31, 2008. The agreements with all other primary mortgage insurers were placed into runoff effective September 26, 2008. The reinsurance agreements with Triad, PMI, UGRIC and Radian were commuted on August 31, 2009, October 2, 2012, April 3, 2014, and October 23, 2017, respectively. The RMIC agreement was terminated on February 2, 2018 and the GMIC aggregate excess of loss minimum agreement was terminated on February 13, 2018.

All agreements between WMMRC and the primary mortgage insurers are on an excess of loss basis, except for a reinsurance treaty with GMIC during 2008, which is reinsured on a 50% quota share basis. Pursuant to the excess of loss reinsurance treaties, WMMRC reinsures a second loss layer which ranges from 5% to 10% of the risk in force in excess of the primary mortgage insurer’s first loss percentage which range from 4% to 5%. Each calendar year, or book year, is treated separately from other years when calculating losses. In return for accepting a portion of the risk, WMMRC receives, net of ceding commission, a percentage of the premium that ranges from 25% to 40%.

As security for the ceding insurers, WMMRC has entered into separate trust agreements with each of the primary mortgage insurance companies whereby a portion of the funds from premiums assumed are held in trust accounts for the benefit of each separate insurer. Pursuant to the terms of the reinsurance agreements, WMMRC is required to keep such assets in trust for a minimum of five years and is subject to claims for up to ten years from termination of obligations arising from the last year in which insurance business was written prior to runoff. Release of funds from the trust by WMMRC requires approval from the primary mortgage insurance companies.

The loss contract reserve balance is analyzed and adjusted quarterly. The balance in the reserve was zero as of both June 30, 2018 and December 31, 2017. The value of this reserve was decreased to zero during the year ended December 31, 2017 and is anticipated to remain at zero. The reserve remained unchanged during the six months ended June 30, 2018 and decreased by $5.4 million during the six months ended June 30, 2017. In periods during which a reduction in the loss contract reserve occurs, a corresponding decrease in expense is reflected in the condensed consolidated statement of operations for the respective period.
