Expense Example Narrative [Text Block]

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. The Examples assume that you invest $10,000 for the time periods indicated, that your investment has a 5% return each year and that the Fund’s annual operating expenses remain as stated in the previous table for the time periods shown except for the fee waiver, which is only reflected for the contractual period. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

These Examples do not reflect fees and expenses of any variable annuity contract or variable life insurance policy. If these were included, the expenses (in dollars) shown would be higher. Keep in mind that this is only an estimate; actual expenses and performance may vary.

During the fiscal year ended December 31, 2024, the portfolio turnover rate was 81% of the average value of the Fund. An underlying fund typically does pay transaction costs when it turns over its portfolio so a higher portfolio turnover rate, which reflects a larger number of securities being bought or sold, may indicate higher transaction costs.

The investment adviser has agreed to reimburse the Fund to the extent the total operating expenses (excluding extraordinary expenses) of the Fund and its proportionate share of fees and expenses of its Pacific Dynamix Underlying Funds exceed 0.59% for Class I shares and 0.39% for Class P shares through April 30, 2026. Prior to that time, the investment adviser may not terminate this agreement without the approval of the Board of Trustees. The investment adviser may recoup from the Fund amounts reimbursed in future periods, not to exceed three years from the date on which the reimbursement took place, provided that the recoupment combined with certain “Other Expenses” would be limited to the lesser of: (i) the expense cap at the time of the reimbursement or (ii) the Fund’s then-current expense cap.​

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. The Examples assume that you invest $10,000 for the time periods indicated, that your investment has a 5% return each year and that the Fund’s annual operating expenses remain as stated in the previous table for the time periods shown except for the expense reimbursement (expense limitation), which is only reflected for the contractual period. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

These Examples do not reflect fees and expenses of any variable annuity contract or variable life insurance policy. If these were included, the expenses (in dollars) shown would be higher. Keep in mind that this is only an estimate; actual expenses and performance may vary.

The Fund, which operates as a “fund of funds” that seeks to achieve its investment goal by investing in other funds, does not pay transaction costs, such as commissions, when it buys and sells shares of those underlying funds (or “turns over” its holdings). During the fiscal year ended December 31, 2024, the portfolio turnover rate was 19% of the average value of the Fund. An underlying fund typically does pay transaction costs when it turns over its portfolio so a higher portfolio turnover rate, which reflects a larger number of securities being bought or sold, may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s and underlying funds’ performance.

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. The Examples assume that you invest $10,000 for the time periods indicated, that your investment has a 5% return each year and that the Fund’s annual operating expenses remain as stated in the previous table for the time periods shown. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

These Examples do not reflect fees and expenses of any variable annuity contract or variable life insurance policy. If these were included, the expenses (in dollars) shown would be higher. Keep in mind that this is only an estimate; actual expenses and performance may vary.

Portfolio Turnover [Text Block]

The Fund, which operates as a “fund of funds” that seeks to achieve its investment goal by investing in other funds, does not pay transaction costs, such as commissions, when it buys and sells shares of those underlying funds (or “turns over” its holdings). During the fiscal year ended December 31, 2024, the portfolio

turnover rate was 50% of the average value of the Fund. An underlying fund typically does pay transaction costs when it turns over its portfolio so a higher portfolio turnover rate, which reflects a larger number of securities being bought or sold, may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s and underlying funds’ performance.

Expense Example Narrative [Text Block]

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. The Example assumes that you invest $10,000 for the time periods indicated, that your investment has a 5% return each year and that the Fund’s annual operating expenses remain as stated in the previous table for the time periods shown except for the fee waiver, which is only reflected for the contractual period. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions.

This Example does not reflect fees and expenses of any variable annuity contract or variable life insurance policy. If these fees and expenses were included, your expenses (in dollars) shown below would be higher. Keep in mind that this is only an estimate; actual expenses and performance may vary.

was 40% of the average value of the Fund. A higher portfolio turnover rate reflects a greater number of securities being bought or sold, which may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
