Factors Affecting Performance [Text Block]
Management’s Discussion of Trust Performance
Over the one-year period ended March 31, 2025, the Hawaiian Tax-Free Trust’s Class A shares returned 1.08% (without sales charge). This performance lagged the 1.22% return of the Trust’s primary benchmark, the Bloomberg Municipal Bond Index. Additionally, the Bloomberg Hawaii Municipal Bond Index, the Trust’s secondary benchmark, returned 1.41% during the same period. The market has remained volatile within a trading range of approximately 100 bps. Several key events have triggered the rates outlook for the market. First, there was a 100 bps cut in the Fed Funds rate in the third and fourth quarter of 2024. Second, the Presidential election ushered in a new Trump administration which got to work quickly altering legacy policies. Both are a source of uncertainty for the market to digest, leading to market volatility.
During the one-year period ended March 31, 2025:
  • Municipal securities with lower credit qualities generally outperformed securities with higher credit qualities. The Trust’s performance relative to its primary benchmark was primarily attributable to the higher quality bias of the Hawaii based municipal securities held by the Trust relative to securities making up the Trust’s primary benchmark index.
  • The Trust’s longer maturity relative to the primary benchmark provided a positive tailwind for the Trust’s relative performance.
  • Security selection was a positive contributor to the Trust’s relative performance for the annual period.

Credit quality ratings are primarily sourced from Moody’s but in the event that Moody’s has not assigned a rating, the Trust will use S&P or Fitch. If these ratings are in conflict, S&P will be used before Fitch. If none of the major rating agencies have assigned a rating, the Trust will assign a rating of NR (non-rated security). The ratings represent their (Moody’s, S&P, and Fitch) opinions as to the quality of the underlying securities in the Trust, and not the Trust itself. The ratings range from AAA (extremely strong capacity to meet financial commitment) to D (in default). Ratings are relative and subjective and are not absolute standards of quality. A pre-refunded bond is secured by an escrow fund of U.S. government obligations (i.e. Treasury securities) and assumes the superior credit rating of the government obligation. The ratings do not predict performance and are subject to change.

The ratings represent their (Moody’s, S&P, and Fitch) opinions as to the quality of the underlying securities in the Trust, and not the Trust itself. The ratings range from AAA (extremely strong capacity to meet financial commitment) to D (in default). Ratings are relative and subjective and are not absolute standards of quality. A pre-refunded bond is secured by an escrow fund of U.S. government obligations (i.e. Treasury securities) and assumes the superior credit rating of the government obligation. The ratings do not predict performance and are subject to change.
Credit Ratings Selection [Text Block] Credit quality ratings are primarily sourced from Moody’s but in the event that Moody’s has not assigned a rating, the Trust will use S&P or Fitch. If these ratings are in conflict, S&P will be used before Fitch.
