        (a) 
         Rate increases for each class of market dominant products in any 12-month period are limited.
     
    
        
        (b) 
         Rates of general applicability are subject to an inflation-based limitation computed using CPI-U values as detailed in  § 3010.12.
     
    
        
        (c) 
         An exception to the inflation-based limitation allows a limited annual recapture of unused rate authority. The amount of unused rate authority is measured separately for each class of mail.
     
    
        
        (d) 
         In any 12-month period the inflation-based limitation combined with the allowable recapture of unused rate  authority equals the price cap applicable to each class of mail.
