text: Interest Rate Risk 
  
  We repaid the debt that was outstanding at June 30, 2010 during 
  
  fiscal 2011, thus, at June 30, 2012, we were not exposed to 
  
  interest rate fluctuations on outstanding debt. We monitor 
  
  depository institutions that hold our cash and cash equivalents, 
  
  primarily for safety of principal and secondarily for maximizing yield 
  
  on those funds. We diversify our cash and cash equivalents among 
  
  counterparties to minimize exposure to any of these entities.
