Fifth Third Bancorp (FITB) said in a regulatory filing that it expects third-quarter losses tied to defaulting loans to rise 24% from the second quarter, to approximately $775 million.

In a filing with the Securities and Exchange Commission ahead of the presentation by the bank's Chairman and Chief Executive officer Kevin Kabat at the Barclays Financial Services Conference Wednesday morning, Fifth Third said it "currently expects net charge-offs to include approximately $110 million in net charge-offs related to (Shared National Credits) compared with $17 million in the second quarter."

However, the Cincinnati bank said it expects losses from shared national credits, or syndicated loans, to improve "significantly" in the fourth quarter.

Fifth Third said it expects commercial loan losses to be approximately $500 million to $525 million and consumer loan losses to be approximately $250 million to 260 million. The bank expects nonperforming loans, those for which repayment is doubtful, "to increase approximately 20% from $2.8 billion at the end of the second quarter to approximately $3.4 billion at the end of the third quarter, with approximately $150 million of the growth related to SNC credits," the filing said.

"Operating trends for the third quarter are expected to be broadly in line with trends previously expected and communicated at the time of our second quarter 2009 earnings announcement on July 23, 2009," Fifth Third's filing said.
