A more thorough explanation:

Rule 504 is a regulation created by the Securities and Exchange Commission (SEC) that allows companies to sell up to $5,000,000 in securities to an unlimited number of buyers in a private placement. This means that companies can sell shares of their company to investors without having to register with the SEC.

Normally, companies that want to sell securities must file a registration statement with the SEC. However, Rule 504 allows companies to avoid this requirement if they comply with certain rules.

One of the main advantages of Rule 504 is that it allows companies to sell securities to a large number of investors without having to go through the time-consuming and expensive process of registering with the SEC. However, because of the $5,000,000 cap, Rule 504 is not commonly used by larger companies.

Compared to other SEC regulations, Rule 504 has fewer restrictions. For example, companies can generally advertise their securities to potential investors, and there are no restrictions on reselling the securities. However, state securities laws may still require companies to disclose certain information to investors and may restrict the resale of securities.

Imagine that a small startup company wants to raise money to fund its operations. The company decides to sell shares of its company to investors in a private placement under Rule 504. Because the company is only looking to raise $1,000,000, it is able to do so without having to register with the SEC.

The company is able to advertise its securities to potential investors and is not required to disclose any information to them. However, the company must comply with state securities laws, which may require it to provide certain disclosures to investors.

Overall, Rule 504 allows small companies to raise money from a large number of investors without having to go through the time-consuming and expensive process of registering with the SEC.
