- Broad issuer mix including general‑obligation and revenue bonds
- Weighting designed to reflect market‑segment representation

Performance also reflects differences in tax status, call features, and liquidity premiums that affect total return.

Risks, Considerations, and Limitations
Investing in or benchmarking against Muni Long 2009 entails specific risks that investors should weigh carefully. Longer duration exposes portfolios to greater interest‑rate volatility, especially when yield curves shift non‑parallelly.

These factors mean the index should be evaluated within a broader, well‑diversified muni framework rather than in isolation.
