Immaterial Error Correction	During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company does not believe this adjustment is material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.
