For optional share purchases, shareholders will also be charged a $2.50 fee for automatic debits from a checking/savings account, a $5.00 one-time fee for online bank debit and/or $5.00 for check. Shareholders will be subject to $0.12 per share fee and either a $10.00 fee (for batch orders) or $25.00 fee (for market orders) for sales of shares held in a dividend reinvestment account.

(4)  Based upon average net assets attributable to our Common Shares during the six months ended April 30, 2025, after giving effect to the anticipated net proceeds of this offering. Assumes the Fund sells 2,168,257 Common Shares at an offering price of $11.53 (the last reported sale price per Common Share on the NYSE as of November 17, 2025). The price per Common Share may be greater or less than the price assumed herein, depending on the market price of the Common Shares at the time of any sale. There is no guarantee that there will be any sales of Common Shares pursuant to this Prospectus Supplement and the accompanying Prospectus. The number of Common Shares actually sold pursuant to this Prospectus Supplement and the accompanying Prospectus may be less than as assumed herein.

(5)  The Adviser receives an annual investment advisory fee of 1.00% based on the Fund’s average daily net assets, computed daily and payable monthly.

(6)  The percentage in the table is based on average total borrowings of $4,899,941 (the average balance outstanding under the Fund’s secured, uncommitted line of credit with BNP Paribas Prime Brokerage International Ltd. during the six month period ended April 30, 2025, representing approximately 1.8% of the Fund’s total average assets, which includes the assets purchased through leverage) and an average interest rate during the six-month period ended April 30, 2025, of 5.39%. There can be no assurances that the Fund will be able to obtain such level of borrowing (or to maintain its current level of borrowing), that the terms under which the Fund borrows will not change, or that the Fund’s use of leverage will be profitable. The Fund currently intends during the next twelve months to maintain a similar proportionate amount of borrowings but may increase such amount to 33 1/3% of the average daily value of the Fund’s total assets.

Purpose of Fee Table , Note [Text Block]

The purpose of the following table and the example below is to help you understand the fees and expenses that Common Shareholders would bear directly or indirectly. The expenses shown in the table under “Other expenses” are estimated for the current fiscal year ending October 31, 2025. The expenses shown in the table under “Interest expenses on bank borrowings” and “Total annual expenses” are estimated based on the Fund’s capital structure for the current fiscal year after giving effect to the anticipated net proceeds of this offering. The tables also reflect the estimated use of leverage by the Fund through bank borrowings representing 1.8% of the Fund’s total average assets, which includes the assets purchased through leverage (consistent with the average percentage of leverage in place during the six month period ended April 30, 2025), and show Fund expenses as a percentage of net assets attributable to Common Shares. The table reflects the anticipated net proceeds of the Common Shares offered pursuant to this Prospectus Supplement and the accompanying Prospectus and assuming the Fund incurs the estimated offering expenses. If the Fund issues fewer than all of the Common Shares available for sale pursuant to the Distribution Agreement and the net proceeds to the Fund are less, all other things being equal, the total annual expenses shown would increase.

General Description of Registrant [Abstract]

Investment Objectives and Practices [Text Block]

Investment Objectives. The Fund’s primary investment objective is to seek high current dividend income, more than 50% of which qualifies for the reduced federal income tax rate, as created by the Jobs and Growth Tax Relief Reconciliation Act of 2003. The Fund also focuses on long-term growth of capital as a secondary investment objective. The Fund’s investment objectives and some of its investment policies are considered fundamental policies and may not be changed without shareholder approval.

Investment Strategies. Under normal circumstances, the Fund invests at least 80% of its net assets in the equity securities of domestic and foreign corporations that pay dividends. The Board of Trustees may change this 80% policy on not less than 60 days’ notice to shareholders. Under normal circumstances, the Fund expects to invest in securities of issuers located in the United States and in approximately 10 to 30 foreign countries.

The Fund may borrow for investment purposes. abrdn Investments Limited (the “Adviser”) currently intends to limit leverage through borrowing to 10% of the Fund’s total assets (calculated at the time of borrowing) and to borrow for investment purposes only when the Adviser believes that the potential return on additional investments acquired with the proceeds of leverage is likely to exceed the costs incurred in connection with the borrowings.
