Bar Chart and Performance Table [Heading] PERFORMANCE SUMMARY
Performance Narrative [Text Block]

The Fund acquired all of the assets and liabilities of the WSTCM Credit Select Risk-Managed Fund, a series of the WST Investment Trust (the “Predecessor Fund”), in tax-free reorganization on September 27, 2024. The Fund adopted the financial statements of the Predecessor Fund, the accounting survivor of the Reorganization. Performance results shown in the bar chart and the performance table below reflect the performance of the Predecessor Fund prior to September 27, 2024. Note that the Fund is managed by a new investment adviser using substantially the same investment strategy as employed for the Predecessor Fund with the addition of a put option strategy designed to generate additional income. In addition, the Fund is an exchange-traded fund, while the Predecessor Fund was a mutual fund prior to the Reorganization. The Predecessor Fund’s investment objective was modified to additionally seek tax efficient monthly income.

 

The bar chart and table that follow provide some indication of the risks of investing in the Fund by showing changes in the Predecessor Fund’s performance from year to year and by showing how the Fund’s and Predecessor Fund’s average annual total returns for one year, five years, and since inception compare with those of a broad-based securities market index and a supplemental index. The bar chart and table show the performance of the Predecessor Fund’s Institutional Shares. How the Predecessor Fund and the Fund have performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is also available on the Fund’s website at www.neosfunds.com.

The Fund acquired the assets and liabilities of the Nationwide Nasdaq-100® Risk-Managed Income ETF, a series of the ETF Series Solutions (the “Predecessor Fund”) on November 8, 2024. The Fund adopted the financial statements of the Predecessor Fund, the accounting successor of the Reorganization. Performance results shown in the bar chart and the performance table below reflect the performance of the Predecessor Fund for periods prior to November 8, 2024. Note that while the investment strategy of the Fund and the Predecessor Fund both include an options strategy designed to reduce volatility and provide a measure of downside protection, the options strategy employed for the Fund has been modified.

 

 

The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for the calendar years ended December 31. The table illustrates how the Fund’s average annual returns over various periods compared with those of a broad measure of market performance as well as an additional index that represents the asset classes in which the Fund invests. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is also available on the Fund’s website at www.neosfunds.com.
