IBMOAiShares iBonds Dec 2026 Term Muni Bond ETF

MUNBCNorthern Trust 2035 Tax-Exempt Distributing Ladder ETF

In short

IBMO No data

MUNB Not a one-and-done maturity fund: MUNB packs a ten-rung municipal ladder into one ticker, paying monthly federally tax-exempt income, returning principal each year as rungs mature, then liquidating in 2035.

Stated mandate

IBMO No data

MUNB The Fund seeks periodic distributions through 2035 consisting of federally tax-exempt income and/or principal. It uses a laddered municipal-bond strategy with maturities spread across annual rungs through the terminal year.

Why people hold it

IBMO No data

  • MUNB One ticker holds a ten-rung muni ladder running to 2035: monthly federally tax-exempt income, plus principal paid back each year as rungs mature. No rolling bonds yourself.flexshares.comnortherntrust.com
  • Bonds are generally held to maturity and the proceeds distributed rather than reinvested, so the cash-flow pattern is set by the ladder itself.flexshares.com
  • Actively run by Northern Trust's muni team across a few hundred bonds, with the annual rungs funded in roughly equal par amounts.flexshares.com

Worth knowing

IBMO No data

  • MUNB Runs 0.18% against a 0.10% median for target-maturity bond funds. Taxable rungs like IBTJ (0.07%) and BSCT (0.10%) cost less, but their income is not tax-exempt.
  • Share price is built to grind down as principal comes back, and distributions can include return of capital, which lowers your cost basis for later.flexshares.comflexshares.com 2
  • Launched in 2025, still small and thinly traded, so bid-ask spreads can be wider than in the big term-bond families.
