Insurance [Abstract] |
Insurance Activity | 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 and UGRIC were commuted on August 31, 2009, October 2, 2012 and April 3, 2014, respectively. All agreements between WMMRC and the primary mortgage insurers are on an excess of loss basis, except for certain reinsurance treaties with GMIC and Radian during 2007 and 2008, which are reinsured on a 50% quota share basis. Pursuant to the excess of loss reinsurance agreements, 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 percentages 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 guaranty companies. Premiums assumed and earned are as follows for the periods ended December 31, 2016, 2015 and 2014, respectively:
| Year ended December 31, 2016 |  | Year ended December 31, 2015 |  | Year ended December 31, 2014 |

Premiums earned | $ | 3,147 |  | $ | 5,121 |  | $ | 7,169 |
The components of the liability for losses and loss adjustment reserves are as follows as of December 31, 2016 and 2015, respectively:

Losses and loss adjustment reserve activity are as follows for the years ended December 31, 2016 and 2015, respectively:
| Year ended December 31, 2016 |  |  | Year ended December 31, 2015 |
Balance at beginning of period | $ | 5,063 |  |  | $ | 18,947 |

Paid or terminated - prior periods |  | (3,583 | ) |  |  | (12,769 | )
Total losses and loss adjustment reserves | $ | 811 |  |  | $ | 5,063 |
The loss contract reserve balance is analyzed and adjusted quarterly. The balances in the reserve were $5.6 million and $9.6 million at December 31, 2016 and December 31, 2015, respectively. The loss contract reserve was established on March 19, 2012 at $63.1 million. The reserve was decreased by $4.0 million, $2.9 million and $33.8 million during the periods ended December 31, 2016, 2015 and 2014, respectively, resulting from the planned runoff of the underlying policies and the commutation of the UGRIC reinsurance agreement in 2014, resulting in corresponding decreases in expense of the respective amount for each period.
