Average net assets

The total value of all the securities in its portfolio, less any liabilities, averaged over a period of time. This is similar to Net Asset Value, but not divided by the number of shares.

This parameter is useful, as it is the basis to derive several key metrics such as:
 * Capital gain "yield", expressed as capital gains / average net assets
 * Foreign tax credit estimate, expressed as foreign taxes paid / average net assets
 * Commission expense ratios, expressed as commissions / average net assets
 * Redemption to Average Net Asset (R/ANA)
 * Redemption to Sales (R/S) ratios

Average net assets is not available in the fund's annual report and must be derived by data mining various SEC filings. Average net assets are not available for ETF share classes of Vanguard index funds, and must be approximated by averaging the beginning net asset figure, mid year figure, and year end figure published in annual and semiannual reports.

EDGAR database
Average net assets are found in the Semi-Annual Report, which is available from the EDGAR database.
