text: We regularly evaluate the likelihood of realizing the benefit for income tax positions we have taken in various federal, state and foreign filings 
  by considering all relevant facts, circumstances and information available. If we believe it is more likely than not that our position will be 
  sustained, we recognize a benefit at the largest amount that we believe is cumulatively greater than 50% likely to be realized. 
  
  Interest and penalties related to income tax matters are classified as a component of income tax expense. 
  
  **Comprehensive Net Earnings**
  Comprehensive net earnings consist of net earnings and other gains and losses affecting equity that are excluded from net earnings. These 
  consist of postretirement plan adjustments, net of related income tax effects and foreign currency translation adjustments. 
  
  **Cash Equivalents**
  Cash equivalents are short-term investments with a maturity of three months or less from the date of purchase and are carried at amortized 
  cost, which approximates fair value. Our cash management system provides for the reimbursement of all major bank disbursement accounts 
  on a daily basis. Accounts payable at the end of 2014 and 2013 included $129 and $133 of checks not yet presented for payment drawn in 
  excess of our bank deposit balances.
