The CFPB is suing Navient over its servicing of student loans. If the lawsuit is successful, we believe restitution, disgorgement, or penalties could be substantial. We are lowering our long-term issuer credit rating on Navient to 'BB-' from 'BB' and our senior unsecured debt rating to 'B+' from 'BB-'. The negative outlook reflects the risks we see stemming from recent litigation against the company and its concentration of large unsecured debt maturities in 2018-2020. On Jan.25, 2017, S&P Global Ratings lowered its long-term issuer credit rating on Navient Corp. to 'BB-' from 'BB'. At the same time we lowered our senior unsecured debt rating to 'B+' from 'BB-' and affirmed our 'B' short-term issuer credit rating. The outlook is negative.
