Section 4.5 — Disclosure Documents & Conduit Theory
Summary List — Mutual Fund Disclosure Documents
How Conduit Theory Works
Four Mutual Fund Disclosure Documents
1. Full (Statutory) Prospectus:
The main disclosure document for investors.
Provides material information needed to make an informed investment decision.
Must be in English, clear, concise, and can be delivered electronically.
Must include:
Fund’s objective
Investment policies and strategies
Sales charges
Management expenses & expense ratio
Services offered
1-, 5-, and 10-year performance histories (or life of fund if shorter)
Required for all new investors before purchase.
2. Summary Prospectus:
A standardized summary version of the full prospectus.
Can be used for solicitation and delivered electronically.
Investors may request a full prospectus at any time.
Must include:
Fund’s name and share class(es)
Ticker symbol
A legend stating this is a summary
Risk and performance information
Fee tables
Investment objectives and strategies
Portfolio holdings and management details
Shareholder information
Financial highlights
3. Statement of Additional Information (SAI):
Provides extra data not found in the prospectus.
Delivered within 3 business days upon request.
Not required for solicitation, but supports transparency.
Typically contains:
Balance sheet
Statement of operations
Income statement
Current portfolio holdings
4. Omitting Prospectus (Tombstone Ad):
An advertisement for a mutual fund, not a full disclosure.
Provides limited, basic information (fund name, investment objective, contact info).
Does not contain sufficient detail to make an investment decision.
Used primarily for marketing and awareness.

Investment Company Structure:
Legal Form: Corporation or trust.
Governed under the Investment Company Act of 1940.
Conduit (Pipeline) Theory:
Purpose: Avoid triple taxation on the same dollar of earnings.
Taxation levels without conduit rule:
Corporation pays taxes on profits.
Mutual fund pays taxes on dividends it received from corporations.
Shareholders pay taxes again on fund dividends.
How Conduit Theory Works
Allows the investment company to pass income directly to shareholders without paying corporate tax, if it qualifies.
Governed by Subchapter M of the Internal Revenue Code (IRC).
Qualification Requirements
Must distribute at least 90% of Net Investment Income (NII) to shareholders.
NII Formula:
Dividends+Interest−Expenses=NII
The fund is taxed only on the undistributed portion of NII.
Example
Fund receives $500,000 in dividends + $600,000 in interest = $1,100,000 gross income.
Expenses = $100,000, so NII = $1,000,000.
Must distribute 90% of $1,000,000 = $900,000 to avoid taxes on that amount.
If it distributes less than $900,000, the entire $1,000,000 is taxed at the fund level.
Shareholders are always taxed on dividends they receive.
