Per SI 02220.005, the following overpayment determinations (made by the FO or an ALJ) require the
                  concurrence of the Assistant Regional Commissioner for Management and Operations Support
                  (ARC MOS) when the overpayment is $20,000 or more:
               
                  - 
                     
                  
 
                  - 
                     
                        •
                        
                           Unwilling to repay (DB TAC)
                           
                         
                      
                   
                  - 
                     
                  
 
                  - 
                     
                        •
                        
                           Unable to locate/out of the country (DM TAC)
                           
                         
                      
                   
                  - 
                     
                  
 
                  - 
                     
                  
 
                  - 
                     
                  
 
                  - 
                     
                        •
                        
                           Compromise settlement (NY TAC) (See note below for other compromise offers that need
                              RO concurrence.)
                           
                           
                         
                      
                   
               
               
                  
                     NOTE: Compromise settlement offers of an overpayment greater than $5,000.00 but less than
                        $20,000.00, where the offer is less than 80% of the overpayment, must also be submitted
                        for ARC MOS concurrence.
                     
                     
                   
                
               For those overpayment inputs that require a 2-PIN process, the input to approve the
                  decision must be made the same day as the decision input (MSOM BUSSR 004.020). Do not make any inputs
                     until contacted by RO staff. If RO staff concurs with the proposed decision, the RO will contact the field office
                  to coordinate the inputs.
               
               NOTE:  RO concurrence policy applies regardless of whether the system will allow the input
                  without a second PIN.
