text: At the end of 2014, 2013 and 2012, $13, $7 and $7 of the ending gross unrecognized tax benefit related to items which, if recognized, would 
  affect the effective tax rate. 
  
  Our income tax expense included a decrease to expense of $1 in both 2014 and 2012, and an increase to expense of $1 in 2013, for tax- 
  related interest and penalties. At the end of 2014, 2013 and 2012, our liability for interest and penalties was $2, $7 and $7. 
  
  We file income tax returns in the U.S. and a limited number of foreign jurisdictions. With few exceptions, we are no longer subject to federal, 
  state and local, or non-U.S. income tax examinations for years before 2010. Unrecognized tax benefits related to federal, state and local tax 
  positions may decrease by $4 by January 30, 2016, due to the completion of examinations and the expiration of various statutes of 
  limitations. 
  
  **NOTE 15: EARNINGS PER SHARE**
  Earnings per basic share is computed using the weighted-average number of common shares outstanding during the year. Earnings per 
  diluted share uses the weighted-average number of common shares outstanding during the year plus dilutive common stock equivalents, 
  primarily stock options. Dilutive common stock reflects the issuance of stock for all outstanding options that could be exercised, and would 
  also reduce the amount of earnings that each share is entitled to. Anti-dilutive shares (including stock options and other shares) are excluded 
  from the calculation of diluted shares and earnings per diluted share because their impact could increase earnings per diluted share.
