Citigroup said it is providing a $500 million credit line to its Falcon Strategies funds, which tumbled 30% last year. The bank disclosed in a regulatory filing with the SEC that it entered into a $500 million credit agreement with the leveraged fund managed by the financial services giant's alternative investment unit. The move makes Citigroup the primary beneficiary of Falcon Plus Strategies and increases Citigroup's assets and liabilities by about $10 billion.. Citigroup said it will move the fund's assets and liabilities onto its balance sheet starting Wednesday. Citigroup is trying to recover from a $9.83 billion fourth-quarter loss.
