How BlackRock reports this
BlackRock combines its open-end mutual fund information into a single annual booklet, separate from the iShares ETF documents.
The BlackRock booklet separates single-state funds, which show a primary state with territories and other states, from multi-state funds, which show a full state table with an AMT row.
BlackRock's booklet reports federal obligations as a percentage of ordinary income for each fund, with a footnote identifying funds above a stated asset level.
