Mine looked similar.
Round 1 - USA Group then transferred to Sallie Mae
Round 2 - Sallie Mae/pre-consolidation
Round 3 - Post-consolidation
Round 1 - eventually fell off, but showed as transferred to another lender.
Round 2 - show as closed/transferred
Round 3 - only group showing a balance
Do you have balances on all of them or do some show as paid/closed/transferred?
