More information about these and other discounts is available from your financial professional and under the heading “How to Purchase Shares” on page 42 of this Prospectus.

(1)

There is a 1.00% contingent deferred sales charge (“CDSC”) for investments of $250,000 or more (see “How to Purchase Shares” below) on Class A shares sold within the first 18 months of purchase, unless you are otherwise eligible to purchase Class A shares without an initial sales charge or are eligible for a waiver of the CDSC (see “Waiver of Contingent Deferred Sales Charges” below).

(2)

If you redeem Class C shares within 12 months after purchase, you will be charged a CDSC of up to 1.00%. The charge will apply to the lesser of the original cost of the Class C shares being redeemed or the proceeds of your redemption and will be calculated without regard to any redemption fee. When you redeem Class C shares, the redemption order is processed so that the lowest CDSC is charged. Class C shares that are not subject to a CDSC are redeemed first. In addition, you will not be charged a CDSC when you redeem shares that you acquired through reinvestment of the Fund’s dividends or capital gains. Any CDSC paid on the redemptions of Class C shares expressed as a percentage of the applicable redemption amount may be higher or lower than the charge described due to rounding.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 114% of the average value of its portfolio.

Wellesley Asset Management, Inc. (“Wellesley” or the “Advisor”), the Fund’s advisor, has contractually agreed to waive its advisory fee and/or reimburse expenses of the Fund until February 28, 2027, to the extent necessary to limit the Total Annual Fund Operating Expenses After Advisory Fee Waiver and/or Expense Reimbursement (subject to the following exclusions) to the annualized rate of 1.30% of the average daily net assets attributable to Class I (the “Expense Limitation”). The Expense Limitation will exclude (not limit) interest charges on borrowings, taxes, brokerage commissions, dealer spreads and other transaction costs, capitalized expenditures, acquired fund fees and expenses, short sale dividends, and extraordinary expenses not incurred in the ordinary course of the Fund’s business (e.g., litigation, indemnification). The expense limitation agreement provides that Wellesley may recoup any amount reimbursed if the Total Annual Fund Operating Expenses After Advisory Fee Waiver and/or Expense Reimbursement fall below the Expense Limitation during the 36 month period following such waiver or reimbursement, provided the Fund is able to effect recoupment while remaining in compliance with the Expense Limitation. This agreement may be terminated upon a writing duly executed by the Advisor and the trust.
