According to Regulation M, what must FINRA receive from offering participants?

Regulation M is specifically designed to prevent manipulation in the market for offered securities during the distribution period. One critical requirement under Regulation M is the notification that offering participants must provide to FINRA regarding whether a restricted period applies to the offering. This restricted period refers to a time frame where certain trading restrictions are in place to promote fair and orderly markets. By notifying FINRA of the applicable restricted period, offering participants contribute to transparency, allowing regulators to monitor trading activities related to the offering and ensure compliance with the rules designed to protect investors.

The other options, while they involve important aspects of securities transactions or offerings, do not specifically align with the direct requirements set forth by Regulation M. Confirmation of sale prices, lists of accredited investors, or details about the use of proceeds, while relevant to broader practices in securities offerings, are not the central elements that Regulation M emphasizes in relation to its anti-manipulation protections.
