text: **Financial Strategy**
  
  A key component of our Ñnancial strategy is our ability to generate free cash Öow. Our deÑnition of free 
  cash Öow, which is not a measure determined in accordance with generally accepted accounting principles, is 
  cash provided by operating activities less purchases of property and equipment plus proceeds from the sale of 
  property and equipment as presented in our consolidated statement of cash Öows. We believe that free cash 
  Öow provides useful information regarding the recurring cash provided by our operating activities after 
  expenditures for property and equipment. It also demonstrates our ability to execute our Ñnancial strategy. 
  Consequently, we have developed incentive programs and we conduct monthly Ñeld operating reviews that 
  help focus our entire company on the importance of increasing free cash Öow. 
  
  Free cash Öow does not represent our cash Öow available for discretionary expenditures because it 
  excludes certain expenditures that are required or that we have committed to such as debt service 
  requirements and dividend payments. Our deÑnition of free cash Öow may not be comparable to similarly 
  titled measures presented by other companies. 
  
  We manage our free cash Öow primarily by ensuring that capital expenditures and operating asset levels 
  are appropriate in light of our existing business and growth opportunities and by closely managing our working 
  capital, which consists primarily of accounts receivable and accounts payable.
