Citigroup Inc. (C) agreed to pay $1.13 billion to settle claims from mortgage-bond investors as it seeks to curb liabilities tied to the financial crisis. It took a $100 million first-quarter charge.

The 68 securitization trusts covered by the settlement issued a combined $59.4 billion in mortgage-backed securities from 2005 to 2008, the New York-based bank said yesterday in a statement. The agreement covers 18 investors represented by Gibbs & Bruns LLP and trustees have until June 30 to accept the deal, the law firm said in a separate statement. The accord must be approved by the Federal Housing Finance Agency.

Citigroup, the third-biggest U.S. bank, is resolving a portion of liabilities tied to mortgages it packaged and sold to investors in the run-up to the 2008 crisis. JPMorgan Chase & Co. (JPM) and Bank of America Corp. (BAC), the two largest U.S. lenders, previously agreed to multibillion-dollar settlements with Gibbs & Bruns clients.
