Acquired fund fees and expenses

The SEC directs mutual fund companies to report the expense ratios of investment companies that are part of a fund's portfolio as "acquired fund fees and expenses (AFFE)." These underlying investment companies can include other open end mutual funds (both in house funds and external funds) as well as variations of the exchange traded closed end fund: closed-end funds, exchange traded funds (ETFs), and Business Development Companys (BDCs).

The SEC is now requiring fund firms to include the underlying expense ratios of business development companies. Vanguard explains this reporting requirement as follows:

"“Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, such as business development companies. These expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. Acquired Fund Fees and Expenses are not included in the Fund’s financial statements, which provide a clearer picture of a fund’s actual operating costs.'"

Table 1. below subtracts the acquired fund fee and expenses from the reported expense ratio. The Extended Market, Small Cap, and Total Market index funds are available in multiple share classes that include admiral and ETF shares. Table 2. provides the expense breakdowns for these share classes. The ratios are the same for both admiral and ETF shares. The "Net ER" column in the tables show the ratio that reflects the expenses Vanguard directly charges for managing the fund. Business Development Companies are mostly small cap companies, so they are more prevalent in small cap indexes and funds that hold investments in small cap stocks. Expense data is derived from April 2011 fund prospectuses.

Vanguard manages a number of equity and balanced mutual funds that are considered fund of funds. SEC regulations require the funds to report the acquired fund fees and expenses of the underlying portfolios. In the following table, we will subtract the acquired fund fee and expense from the reported fee. This results in the ratio that reflects the expenses Vanguard directly charges for managing the fund.

One should note the variable annuity portfolios also incur added insurance company mortality expense risk and administrative expense charges.
