| Performance Narrative [Text Block] | The bar chart and performance table below show the variability of the Funds returns, which is some indication of the risks of investing in the Fund. The bar chart shows performance of the Funds Class I shares during the past ten calendar years. The performance table compares the performance of the Funds Class I shares over time to the performance of a broad-based market index: the Bloomberg U.S. Aggregate Bond Index and a supplemental index: the ICE BofA All Convertibles Exclude Mandatory All Qualities Index. The Fund offers multiple share classes, which are subject to different fees and expenses that will affect their performance. You should be aware that the Funds past performance (before and after taxes) may not be an indication of how the Fund will perform in the future. Although Class A and Class C shares have similar returns to Class I shares because the classes are invested in the same portfolio of securities, the returns for Class A and Class C shares are different from Class I shares because Class A and Class C shares have different expenses than Class I shares. Updated performance information is available at no cost by visiting www.MillerFamilyOfFunds.com or by calling 1-781-416-4000.
