• The nation's foreclosure crisis prompted a surge in mortgage modifications. The government-sponsored Home Affordable Modification Program (HAMP) helped facilitate a majority of them. As the Making Home Affordable website explains, the government does not require lenders to participate in HAMP, however, the nation's largest lenders take part, according to Treasury Department data on the program.
  
  

Bank of America

• Through August 2010, the Treasury Department estimates that Bank of America led the way in terms of approving trial and permanent modifications, with 152,710. The total was split almost evenly between trial and permanent modifications. If a borrower qualifies for HAMP, the lender puts him on a trial modification. After making three consecutive, on-time payments, the modification becomes permanent. As of July 2010, Bank of America canceled 148,129 HAMP trials and did not approve 89,791 initial HAMP applications. Out of the rejected applications, 6,261 resulted in completed foreclosures, as of July 2010.
