The underlying index utilizes a market capitalization weighting scheme and is rebalanced on the final business day of each month.

SPAB's YTM is published on the fund's factsheet on the issuer's website — it differs from the trailing-12-month yield because YTM reflects current bond prices rather than historical income paid.
