Subsequent Events [Text Block]	SUBSEQUENT EVENTS On April 6, 2015, the Company, National Western Life Group, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Newco”), and NWLIC MergerCo, Inc., a Colorado corporation and wholly-owned subsidiary of Newco (“MergerCo”), entered into an Agreement and Plan of Merger (the “Reorganization Agreement”), that provides for the merger (the “Merger”) of the Company with MergerCo, with the Company surviving the Merger as a wholly-owned subsidiary of Newco. The Merger provides for the conversion of each share of Class A common stock, par value $1.00per share, of the Company and each share of Class B common stock, par value $1.00 per share, of the Company issued and outstanding immediately prior to the effective time of the Merger, into one duly issued, fully paid and non-assessable share of Class A common stock, par value $0.01 per share, of Newco ("Newco Class A Stock") or Class B common stock, par value $0.01 per share, of Newco, respectively (collectively with the other transactions contemplated by the Reorganization Agreement, the “Reorganization”). In addition, each outstanding option to acquire, or SARs relating to, shares of the Company's Class A Stock would automatically convert into an option to acquire, or SARs relating to, on the same terms and conditions, an identical number of shares of Newco Class A Stock. Upon completion of the Reorganization, Newco, a Delaware corporation, would, in effect, replace the Company, a Colorado corporation, as the publicly held corporation traded on the NASDAQ Global Select Market under the symbol “NWLI”, and the holders of the Company's Class A Stock and Class B Stock would hold the same number of shares and same ownership percentage of Newco after the Reorganization as they held of the Company immediately prior to the Reorganization. The directors of Newco immediately following the Reorganization would be the same individuals who were directors of the Company immediately prior to the Reorganization. The Reorganization Agreement is subject to specified conditions, including approval by the Company's shareholders at its Annual Meeting of Shareholders (the “Annual Meeting”), which is currently scheduled for Friday, June 19, 2015. If approved by the Company’s shareholders at the Annual Meeting and the other conditions set forth in the Reorganization Agreement are satisfied, it is currently expected that the Reorganization would be completed in the latter part of 2015.
