Expense Ratio - Changes in Expense Ratio (fixed & Variable Expenses)

Changes in Expense Ratio (fixed & Variable Expenses)

Generally, unlike past performance, expenses are very predictive. Funds with high expenses ratios tend to continue to have high expenses ratios. An investor can examine a fund's "Financial Highlights" which is contained in both the periodic financial reports and the fund's prospectus, and determine a fund's expense ratio over the last five years (if the fund has five years of history). It is very hard for a fund to significantly lower its expense ratio once it has had a few years of operational history.

This is because funds have both fixed and variable expenses, but most expenses are variable. Variable costs are fixed on a percentage basis. For example, assuming there are no breakpoints, a .75% management fee will always consume .75% of fund assets, regardless of any increase in assets under management. The total management fee will vary based on the assets under management, but it will always be .75% of assets.

Fixed costs (such as rent or an audit fee) vary on a percentage basis because the lump sum rent/audit amount as a percentage will vary depending on the amount of assets a fund has acquired. Thus, most of a fund's expenses behave as a variable expense and thus, are a constant fixed percentage of fund assets. It is therefore, very hard for a fund to significantly reduce its expense ratio after it has some history. Thus, if an investor buys a fund with a high expense ratio that has some history, he/she should not expect any significant reduction.
