IBMV provides a self-liquidating portfolio of municipal bonds that mature by December 2033, offering tax-exempt income with a defined end date. Think of it as a muni bond ladder compressed into a single ticker that will return principal at maturity.

How It Works

The fund holds investment-grade municipal bonds from various states and sectors that mature before December 31, 2033, then distributes the proceeds and closes. As bonds mature or are called, the portfolio naturally shortens in duration and concentrates in remaining holdings. The 0.27% yield reflects the tax-equivalent benefit — roughly equivalent to a 0.40-0.45% taxable yield for high earners.

Key Features

  • Zero expense ratio makes this cheaper than building your own muni ladder through individual bonds
  • Defined maturity date eliminates reinvestment risk — you know exactly when you get your money back
  • Federal tax-exempt income with potential state tax benefits depending on your residence and holdings

Risks

  • Interest rate risk diminishes over time but could cause 5-7% drawdowns if rates spike 100bps in early years
  • Credit concentration risk increases as bonds mature — by 2032 you might own just 10-20 positions
  • AMT exposure could eliminate tax benefits for some high-income investors subject to alternative minimum tax

Who Should Own This

Perfect for high-income earners in 32%+ tax brackets who need municipal exposure for a specific future liability — think funding a 2033 college tuition payment or matching a retirement spending bucket. The defined maturity makes it superior to perpetual muni funds for liability matching, while the zero fee beats separately managed accounts.
