It is clear that our funds-of-funds offerings will become increasingly large shareholders of Vanguard Total Bond Market Index Fund, noted Vanguard Chief Investment Officer George U. Sauter. To mitigate the impact of future rebalancing on that fund, we believe it is necessary and prudent to introduce a second bond market index fund. Holdings in the Vanguard Total Bond Market Index Fund that the firms 11 LifeStrategy and Target Retirement funds now hold will be transferred to the new fund.
Certainly, assets in the target retirement funds offered by Vanguard have more than doubled over the past three years, to $33.5 billion.
