In short

IBMO —No data

MYMK A single rung of a muni ladder: MYMK holds tax-exempt bonds maturing in 2031, then returns remaining principal and closes on or about December 15, 2031. Unlike the big index ladders, a State Street team picks the bonds.

Stated mandate

IBMO —No data

MYMK The fund is an actively managed target-maturity municipal bond strategy focused primarily on bonds maturing in 2031. It seeks current federal-tax-exempt income while also seeking capital preservation.

Why people hold it

IBMO —No data

• MYMK Actively managed rather than index-tracked: the team works top-down across sectors and issuers, with the ICE 2031 Maturity US Broad Municipal Index as the yardstick.businesswire.comssga.com
• The defined end date does the work of a maturity: the fund distributes any remaining principal and liquidates on or about December 15, 2031.ssga.com
• Income is exempt from regular federal income tax and paid monthly, with preservation of capital named as the second goal.
• Roughly 80 bonds spread issuer risk that you would carry concentrated if you bought a couple of individual munis yourself.

Worth knowing

IBMO —No data

• MYMK The 0.20% fee sits above index-run ladder rungs like iShares iBonds (IBTJ) and Invesco BulletShares (BSCT). That is the price of a manager picking bonds.
• Small and thinly traded next to the established ladder families, so the bid-ask spread is a real part of your cost.
• In the target year, proceeds from bonds maturing before the liquidation date may sit in cash and cash equivalents, which can trim income in the final stretch.ssga.com
