I don't know why I didn't notice this before-looks like Citigroup will have a controlling interest-50% soon but not difficult to pick up a few shares from shareholders here and there to get to 51%
It's an ongoing process.
Jan. 29 (Bloomberg) -- Banco de Chile rose the most in more than a week, extending gains after Citigroup Inc. agreed to buy an additional stake in its holding company.
Banco de Chile, controlled by Chile’s Luksic family, climbed 2.6 percent to 48.70 pesos. The Luksic’s investment vehicle Quinenco SA surged the most in more than two years.
Citigroup exercised an option to buy 8.5 percent of LQ Inversiones Financieras SA, or LQIF, the company through which Quinenco controls Banco de Chile, according to a Quinenco statement posted today on the Chilean regulator’s Web site.
"In 2007, the New York-based bank acquired 32.96 percent of LQIF and an option to increase that to 50 percent under an agreement with Quinenco to combine their Chilean operations"
Sort of interesting that some of these large family owned are giving up control-I really don't see why. I guess it's simply the money, you just can't be rich enough.

The Ibanez family gave up control of D & S(to walmart) not long ago as well. It was just 50% but walmart picked up shares to make it 58% I think,
