BlackRock’s municipal closed-end funds have completed a set of reorganizations and adopted discount programs for 2026. Seven acquired municipal funds have been combined into three survivor funds, with share exchanges based on each fund’s net asset value at the close of business on February 6, 2026.
Common shareholders of each acquired fund received survivor fund shares equal in aggregate net asset value to their prior holdings, with cash paid instead of fractional shares. Preferred shareholders received survivor fund preferred shares on a one-for-one basis, matching their prior liquidation preference. The transactions are expected to be non-taxable events.
Each survivor fund will also participate in a 2026 Discount Management Program. If a fund’s common shares trade at an average daily discount to NAV of more than 10.00% during the January 1–September 30, 2026 measurement period, it intends to conduct a tender offer to repurchase at least 5% of its outstanding common shares at 98% of NAV, calculated the day after the tender expires.
