Credit Suisse Group AG may reach an agreement as soon as this week to settle a U.S. investigation into its handling of mortgage-linked securities before the 2008 financial crisis, Reuters reported. Switzerland’s second-largest bank is confident it can reach a resolution for less than the $5 billion to $7 billion that the Department of Justice has demanded, the publication quoted an unidentified person familiar with the talks as saying, without specifying when that request was made.
