Why 40 Act Funds Dominate Retirement Plans
These funds became the default choice for 401(k)s and 403(b)s because:
- Built-in investor protections from the 1940 Act
- Daily liquidity meets retirement plan needs

40 Act funds disclose fees through:
- Expense Ratio (annual % of assets):

- Administrative costs
- 12b-1 marketing fees
- Share Classes (same portfolio, different fees):
- Class A: Front-end load
- Class C: Back-end load
- Class I: Institutional (lowest fees)
- Class R: Retirement plans
Example: A fund might offer:

- Admiral shares at 0.10%
- Institutional shares at 0.02%
Regulatory Safeguards
The 1940 Act requires:
- Independent directors (at least 40% of board)

How to Evaluate 40 Act Funds
