Total annual fund operating expenses after fee waiver and/or expense reimbursements2					0.86				0.61

¹  "Other expenses" include "Acquired fund fees and expenses," which were less than 0.01% of the average net assets of the fund. Since the "Acquired fund fees and expenses" are not directly borne by the fund, they are not reflected in the fund's financial statements, and therefore

the amounts listed in "Total annual fund operating expenses" and "Total annual fund operating expenses after fee waiver and/or expense reimbursements" may differ from those presented in the financial highlights.

²  The fund and UBS Asset Management (Americas) Inc. ("UBS AM") have entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS AM is contractually obligated to waive its management fees and/or reimburse expenses so that the fund's ordinary total operating expenses of each class through November 30, 2023 (excluding, as applicable, (i) dividend expense, borrowing costs, and interest expense relating to short sales, and (ii) expenses attributable to investment in other investment companies, interest, taxes, brokerage commissions, expenses related to shareholders' meetings, and extraordinary expenses) would not exceed, prior to August 1, 2022, 0.91% for Class A and 0.66% for Class Y. Effective August 1, 2022, the expense caps are 0.86% for Class A and 0.61% for Class Y. The fund has agreed to repay UBS AM for any waived fees/reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the class expenses in any of those three years to exceed these expense caps and that UBS AM has not waived the right to do so. The fee waiver/expense reimbursement agreement may be terminated by the fund's board at any time and also will terminate automatically upon the expiration or termination of the fund's advisory contract with UBS AM. Upon termination of the agreement, however, UBS AM's three year recoupment rights will survive.

The section captioned "PACE Alternative Strategies Investments Fund Summary" and sub-captioned "Annual fund operating expenses" on page 68 of the Multi-Class Prospectus is revised by replacing the table and footnotes in their entirety with the following:

Management fee waiver/expense reimbursements3									0.17								0.16
Total annual fund operating expenses after fee waiver and/or expense reimbursements3									2.84								2.60

¹  "Dividend expense, borrowing costs and related interest expense attributable to securities sold short" are based on estimated amounts for the current fiscal year.

²  These "Acquired fund fees and expenses" are based on estimated amounts for the current fiscal year. Since the "Acquired fund fees and expenses" are not directly borne by the fund, they are not reflected in the fund's financial statements, and therefore the amounts listed in "Total annual fund operating expenses" and "Total annual fund operating expenses after fee waiver and/or expense reimbursements" may differ from those presented in the financial highlights.

³  The fund and UBS Asset Management (Americas) Inc. ("UBS AM") have entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS AM is contractually obligated: (1) to waive its management fees through November 30, 2022 to the extent necessary to offset the cost savings to UBS AM for allocating a portion of the fund's assets to other unaffiliated pooled investment vehicles and index

futures; and (2) waive its management fees and/or reimburse expenses so that the fund's ordinary total operating expenses of each class through November 30, 2023 (excluding, as applicable, (i) dividend expense, borrowing costs, and interest expense relating to short sales, and (ii) expenses attributable to investment in other investment companies, interest, taxes, brokerage commissions, expenses related to shareholders' meetings, and extraordinary expenses) would not exceed, prior to August 1, 2022, 1.88% for Class A and 1.63% for Class Y. Effective August 1, 2022, the expense caps are 1.83% for Class A and 1.58% for Class Y. The fund has agreed to repay UBS AM for any waived fees/reimbursed expenses (pursuant to item (2)) to the extent that it can do so over the following three fiscal years without causing the class expenses in any of those three years to exceed these expense caps and that UBS AM has not waived the right to do so. The fee waiver/expense reimbursement agreement may be terminated by the fund's board at any time and also will terminate automatically upon the expiration or termination of the fund's advisory contract with UBS AM. Upon termination of the agreement, however, UBS AM's three year recoupment rights will survive.

The section captioned "Investment management, administration and principal underwriting arrangements" and sub-captioned "Investment management and administration arrangements" beginning on page 93 of the SAI is revised by replacing the eighth paragraph of that sub-section in its entirety with the following:

UBS AM is contractually obligated to waive all or a portion of its investment management and administration fees and/or to reimburse the funds for certain operating expenses of Class A, Class Y and Class P in order to maintain the total annual operating expenses of each such class (excluding expenses attributable to (1) dividend expense, borrowing costs and interest expense relating to short sales, and (2) investment in other investment companies, interest, taxes, brokerage commissions, expenses related to shareholders' meetings and extraordinary expenses) through November 30, 2022 for certain funds (and through November 30, 2023 for PACE Intermediate Fixed Income Investments and PACE Alternative Strategies Investments) at a level not to exceed certain specified amounts as shown in the chart below. Each fund will repay UBS AM for any such waived fees/reimbursed expenses during the three-year period following the period during which UBS AM waived fees or reimbursed expenses, to the extent that repayment can be made without causing the operating expenses of the fund or class during a year in which repayment is made to exceed these expense caps.

Effective August 1, 2022, the expense caps are 1.83% for Class A and 1.58% for Class Y. The fund has agreed to repay UBS AM for any waived fees/reimbursed expenses (pursuant to item (2)) to the extent that it can do so over the following three fiscal years without causing the class expenses in any of those three years to exceed these expense caps and that UBS AM has not waived the right to do so. The fee waiver/expense reimbursement agreement may be terminated by the fund's board at any time and also will terminate automatically upon the expiration or termination of the fund's advisory contract with UBS AM. Upon termination of the agreement, however, UBS AM's three year recoupment rights will survive. false 2022-08-01 2022-08-01 2022-08-01 497 0000930007 N-1A PACE SELECT ADVISORS TRUST PFXAX PFXYX PIFAX
