FACTBOX - Citigroup's action plan

NEW YORK (Reuters) - Citigroup (C.N) announced a series of measures aimed at shedding $400 billion (205 billion pounds) worth of assets over the next three years and increasing revenue by 10 percent per year. Citi's change in strategy comes after the bank had over $45 billion in write-downs and saw its stock price halved over the past year.

Planned actions by the largest U.S. bank include:

*Shed $400 billion of assets, or nearly 20 percent of its assets. The bank will mainly be selling assets and businesses, but will also let some mature.

*Slim down its fixed-income assets and expand operations in prime brokerage, derivatives, and electronic trading.

*Citi's securities and derivatives trading businesses will focus on trading for clients rather than trading the bank's capital.

*Focus more resources in emerging markets, where growth is stronger.

*Keep about 75 percent of revenue in stable earnings generators, and 25 percent in riskier areas.

*Reintroduce the marketing tag line "Citi never sleeps."

*Shrink the mortgage portfolio. It will still make mortgage loans, but will hold less of the loans they make.
