Income Taxes.

We are subject to federal, state, local and foreign income taxes. Along with our U.S. subsidiaries, we file a U.S. federal consolidated income tax return. We are no longer subject to U.S. federal, state, foreign and local income tax examinations by tax authorities for years before 2008. During 2013, the Internal Revenue Service (IRS) commenced a limited-scope audit of our consolidated U.S. income tax return for 2010. One issue is still outstanding with the IRS which occurred in years 2003 through 2007. This matter was appealed through the IRS Office of Appeals and subsequently was heard by the United States Tax Court at trial during November 2011, and a decision is expected during 2013. Currently, we are also under examination in various states. We do not anticipate that adjustments, if any, regarding the 2003 through 2007 disputed issue or state examinations will result in a material change to our consolidated statement of earnings, financial condition, statement of cash flows or earnings per share.
