Our read on MUNB

ETF.net Research

CNot 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

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

  1. 01One 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.comntam.northerntrust.com
  2. 02Bonds 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
  3. 03Actively 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

  1. 01Runs 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.
  2. 02Share 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
  3. 03Launched in 2025, still small and thinly traded, so bid-ask spreads can be wider than in the big term-bond families.
