How the SRP is Calculated - SLS

Principal Balance as of MPF Sale Date x SRP = SRP Paid to the PFI    

The Servicing Released Premium (SRP) is paid based on the fee schedule in effect at the time the Delivery Commitment is issued (date locked in). MPF Xtra servicing released to SLS is a full net funding product. MPF buys the loan, nets out any fees including the escrows and pays the SRP simultaneously.
