| Performance Narrative [Text Block] | Performance: The following bar chart and table provide some indication of the risks of investing in the Fund. The Fund is adopting the performance of the Predecessor Mutual Fund as the result of the Reorganization. Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the Predecessor Mutual Fund’s performance from year to year (represented by the performance of the Predecessor Mutual Fund’s Class I Shares). The table shows how the Predecessor Mutual Fund’s average annual returns (represented by the average annual returns of the Predecessor Mutual Fund’s Class I Shares) for 1 year and since inception compared with those of an appropriate broad-based securities market index and additional securities market indexes. Effective as of the Reorganization, the ICE BofA Low Duration U.S. ABS & CMBS Equal Par Index replaced the Bloomberg U.S. Mortgage-Backed Securities (MBS) Index as the Fund’s secondary benchmark index because the Adviser believes it more closely reflects the market segment in which the Fund invests. Had the Predecessor Mutual Fund been structured as an ETF, its performance may have differed. The Fund’s (and the Predecessor Mutual Fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
