It looks like billionaire Abigail Johnson is moving closer to the Fidelity throne.
This month the daughter of Edward "Ned" Johnson III, lord of the world's largest mutual fund company, took charge of the board governing the company's fixed-income and asset-allocation funds. She now oversees 161 funds with more than $650 billion in assets.

A spokesman for Fidelity would not comment on the company's succession plans. He said the move was the logical next step in its strategy to split its board of trustees in half, and Ned Johnson has no plans of retiring.
Like the majority of the female billionaires in the world, Johnson inherited her fortune--yet still holds tremendous sway over her company. Today she's worth an estimated $8.5 billion, ranking her eighth on the new Forbes list of the world's richest women.
Topping the list is Christy Walton, who is worth $20 billion. Walton is the widow of Wal-Mart ( WMT - news - people ) scion John Walton, who died in a plane crash in 2005. Right behind her is Alice Walton, worth $19.5 billion.
