iShares iBonds Dec 2021 Term Muni Bond ETF (IBMJ) seeks to track the investment results of an index composed of investment-grade, AMT-free U.S. municipal bonds maturing between January 1, 2021, and December 2, 2021; the fund holds a market-value-weighted portfolio of such bonds issued by state and local governments or agencies, providing tax-exempt income to investors. Managed by BlackRock, Inc. and launched on September 1, 2015, the ETF is headquartered in New York, New York, and primarily targets U.S. investors seeking defined-term exposure to the municipal bond market without federal alternative minimum tax implications. The ETF operates within the fixed income segment, focusing on short-duration, high-quality muni bonds from diverse issuers across U.S. states.
In line with the design of the iBonds series, IBMJ underwent liquidation proceedings as its underlying bonds matured, with the final net asset value calculated around December 6, 2021, at approximately $25.58 per share and the fund delisted shortly thereafter; shareholders received cash proceeds from the liquidation, transitioning the portfolio to short-term instruments and cash in the final months. BlackRock, the issuer, has continued to expand its iBonds muni bond ETF lineup with later target maturities, such as the iShares iBonds Dec 2025 Term Muni Bond ETF (IBMN), which announced its own termination schedule for December 2025, and recently launched innovative fixed income products like the iShares Total USD Fixed Income Market ETF (BTOT) in December 2025 to broaden U.S. bond market access.
