| Performance Narrative [Text Block] | The following bar chart and table are intended to help you understand some indication of the risks of investing in the Fund. The bar chart illustrates the Member Shares' volatility by showing how performance has varied from year to year for each full calendar year over the past 10 years. The table compares the Fund's average annual total returns of the Fund's share classes over the same period to a broad-based securities market index with investment characteristics similar to those of the Fund and the Fund's benchmark index. We assume reinvestment of dividends and distributions.Performance data for the classes varies based on differences in their fee and expense structures and reflects any expense limitations in effect during the periods shown. Remember, historical performance (before and after taxes) does not necessarily indicate what will happen in the future. The Fund’s most current performance information is available on the Fund’s website at vcm.com or by calling (800) 235-8396. |

| Performance Table Narrative | After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain situations, the return after taxes on distributions and sale of fund shares may be higher than the other return amounts. A higher after-tax return may result when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. The actual after-tax returns depend on your tax situation and may differ from those shown. If you hold your shares through a tax-deferred arrangement, such as an individual retirement account (“IRA”) or 401(k) plan, the after-tax returns shown in the table are not relevant to you. Please note that after-tax returns are shown only for the Member Shares and may differ for each share class. |
