California Limited Term Municipal Fund


Thornburg California Limited Term Municipal Fund is a laddered portfolio of investment-grade municipal bonds from the Golden State, with maturities of one to 10 years, and with an average duration around 3.5 years. Actively laddering portfolios helps mitigate the risks of bond investing and can generate attractive returns over time.


Thornburg Municipal Bond Team“Unlike many other California single-state funds, this fund has a relatively short duration, which protects against the risk of rising interest rates. The fund is a 10-year, actively managed ladder and seeks to generate attractive income without excessive shifts in principal valuations.”

We build a portfolio of staggered maturities so that a portion will mature each year. Money from maturing bonds provides an organic source of cash flow, and is typically reinvested in longer-maturity bonds at the top range of the ladder.

Laddering tends to perform well against other strategies because it captures price appreciation as bonds age and their remaining life shortens, and it reinvests principal from shorter, lower-yielding bonds into longer, higher-yielding bonds.

The fund’s laddered portfolio structure is one of many important contributors (credit research also among them) to the total return an investor receives over an appropriate holding period.


In bond investing, nothing is more important than determining whether the party to whom you propose to lend money has the ability and willingness to pay you back in full and on schedule.

We conduct thorough, bottom-up credit research on every bond we purchase to understand the ability of the issuer to repay obligations, and to ensure that investors are adequately compensated for the risk assumed.


The portfolio is composed of roughly 400 separate positions, in part to ensure that a potential default or price decline of any one issuer has a minimal impact upon the net asset value of the portfolio.

In adjusting position sizes within the portfolio, we take into account the credit quality of the issuer (with higher-quality credits typically being afforded larger position sizes), the extent to which each issue contributes to the duration of the portfolio, and of course, prospectus limitations.

Keep in mind that California Limited Term Municipal Fund is not as diversified as our national funds, and macroeconomic trends within the state may impact all securities within the fund.

It’s important for investors to match their investment horizon to the duration of the strategy in which they’re invested, and to diversify tax-exempt assets across the yield curve.

This is why Thornburg offers a range of strategies—from the Low Duration Municipal Fund on the short end to the Strategic Municipal Income Fund on the long end—to provide a home to match every time horizon.
