Columbia Acorn NY 529 Portfolio: Class A

* Expense ratios are as of the plan’s most recent Program Brochure & Tuition Savings Agreement. Performance may reflect waivers or reimbursements of fund expenses by the advisor or its affiliates. Absent these waivers, or reimbursement arrangements, performance results may be lower. View a list of portfolios for which the investment advisor or its affiliates has agreed to reimburse or waive a portion of the fund expenses. Unless a specific end date is provided, the waiver or reimbursement may be revised or discontinued at any time.

Performance data quoted represents past performance, and current performance may be lower or higher. Past performance is no guarantee of future results. The investment return and principal value will fluctuate so that, when redeemed, units may be worth more or less than the original cost. Total returns assume the reinvestment of all underlying fund distributions at NAV and may reflect any voluntary waiver or reimbursement of fund expenses by the advisor or its affiliates. Absent these waivers or reimbursement arrangements, performance results may have been lower. Please visit www.columbiamanagement.com for daily and most recent month-end performance updates.  Portfolio unit value (PUV) returns do not include sales charges or contingent deferred sales charges (CDSC). If they were included, returns would have been lower.
