Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Litigation Certain lawsuits have been filed against the Company. These lawsuits generally involve matters related to the claims aspect of the Company’s business. The Company contests liability and/or the amount of damages as appropriate in each pending matter. In accordance with applicable accounting guidance, the Company establishes an accrued liability for legal matters when those matters present loss contingencies that are both probable and estimable. Legal proceedings are subject to many uncertain factors that generally cannot be predicted with assurance, and the Company may be exposed to losses in excess of any amounts accrued. The Company currently estimates that the reasonably possible losses for legal proceedings, whether in excess of a related accrued liability or where there is no accrued liability, and for which the Company is able to estimate a possible loss, are immaterial. This represents management’s estimate of possible loss with respect to these matters and is based on currently available information. This estimate of possible loss does not represent our maximum loss exposure. The legal proceedings underlying the estimate will change from time to time and actual results may vary significantly from current estimates.
