A more thorough explanation:

An abbreviated term sheet is a document that provides investors with important information about an offering that is not included in the prospectus or confirmation. It is also known as a letter of intent.

The term sheet includes a description of the securities being offered and any material changes to the issuer's affairs that are required to be disclosed on SEC Form S-3 or F-3. This information is necessary for investors to make informed decisions about whether to invest in the offering.

An example of an abbreviated term sheet would be a document provided to potential investors in a startup company's initial public offering (IPO). The term sheet would include information about the company's financials, the number of shares being offered, and any risks associated with investing in the company.

Another example would be a term sheet provided to investors in a real estate investment trust (REIT). The term sheet would include information about the properties owned by the REIT, the expected return on investment, and any fees associated with investing in the REIT.

These examples illustrate how an abbreviated term sheet provides investors with important information about an offering that is not included in the prospectus or confirmation. This information is necessary for investors to make informed decisions about whether to invest in the offering.
