What it means
The prospectus is the main sales and disclosure document for a fund. It is meant to be readable and focuses on the key points, such as the fund's goals, main risks, costs and past performance.
A lot of detail would make it hard to read, so the finer points go in a second document, the SAI. The SAI covers subjects such as the fund's history and structure, the investment techniques it may use, and limits on its borrowing and holdings.
It also lists the trustees and officers, explains how the fund manager is paid, and describes how the fund buys and sells securities. Portfolio manager details, such as how they are paid and the shares they own in the fund, can also be found there.
Because it is legally part of the fund's registration, the SAI must be accurate and kept up to date. It is normally updated at the same time as the prospectus each year.
Funds must send it to investors on request, and many post it on their website. For finance professionals and business owners, the SAI is useful for deeper due diligence.
If your company's retirement plan offers a mutual fund, the SAI can show how the fund is managed, what conflicts of interest exist and how trades are executed. Those details are rarely in marketing materials.
A practical tip is to read the SAI selectively. It is long and technical, so look for sections on investment restrictions, fees paid to advisers, portfolio turnover and brokerage practices.
These sections reveal how the fund actually operates. Investors in funds outside the United States will meet similar documents under different names.
Many countries require an equivalent set of detailed fund documents that sit behind a short key information document. The concept is the same: a brief summary on top and the full operating details underneath.
In practice
Real-world examples.
Example
A company treasurer is choosing a money market fund for $5,000,000 of surplus cash. She reads the SAI to see what types of securities the fund may hold and whether it can borrow. A fund that can borrow heavily may be riskier than its name suggests.
Example
A retirement plan trustee reviews the funds offered to employees. The trustee checks the SAI for how the portfolio manager is paid and whether the manager owns shares in the fund. A manager who invests personally in the fund shares the investors' risk.
Example
A financial adviser preparing a report for a client asks the fund company for the SAI. She wants to confirm the fund's investment restrictions before recommending it. She also notes how often the fund trades, which affects its costs.
Case study
Seen in the real world.
Westbrook Industries is an entirely fictional manufacturer with a company retirement plan. In this illustrative story, its plan committee is reviewing a fund that has attracted many employees.
The committee asks for the fund's SAI and finds that the fund's adviser also earns fees from related services, and that the fund can invest in certain derivatives. These details were not obvious from the prospectus.
The committee decides to keep the fund but adds the points to its annual review and informs employees. The illustrative lesson is that the SAI reveals operating details that help trustees make better decisions. The committee records its review in the minutes, so that a future committee can see what was checked and when. It also asks the fund company to confirm that the SAI it reviewed is the latest version. Employees who attended the briefing said the plain-English summary of the SAI findings was the first time they understood who was paid what for running their fund.
Watch out
Common mistakes.
- Relying only on the prospectus, when the SAI holds important details about management, fees paid to advisers and day-to-day operations of the fund.
- Assuming the SAI is a marketing document, when it is a legal disclosure that must be accurate and kept up to date by the fund.
- Reading it from start to finish without a purpose, instead of going to the sections that matter for the decision you are making.
Questions
People also ask.
Is the SAI part of the prospectus?
It is separate but legally linked, and it supplements the prospectus, so the two should be read together when you need the full picture.
How do I get one?
Ask the fund company, which must provide it free on request, or find it on the SEC's EDGAR website, where all current filings for the fund are listed.
How often is it updated?
Usually once a year, at the same time as the prospectus, and whenever there is a material change.
