What this filing shows
·Every sentence is a value as filed on SEC Form D
Stonepeak Infrastructure Fund IV - U (Side Car) LP is a Delaware limited partnership that filed a Form D with the SEC on October 23, 2020, describing itself as a private equity fund. The offering claims Rule 506(b), Section 3(c), Section 3(c)(7) and covers pooled investment fund interests. Stonepeak Infrastructure Fund IV - U (Side Car) LP reported that the first sale had not yet occurred as of the Form D filed October 23, 2020, so no amount sold or investor count is on file. The total offering amount is listed as indefinite. The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. Because the fund also relies on Section 3(c)(7), each investor must be a qualified purchaser, generally an individual with at least $5 million in investments. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated. The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly. The issuer's address of record is 55 Hudson Yards, 550 West 34th Street, 48th Floor, New York, NY 10001.

Grouped from Form D issuer names (generation, sleeve, jurisdiction and legal-form tokens removed); a name-only match, so abbreviated or renamed vehicles can be missed. Sold and investor figures are each vehicle's latest Form D; sleeves that report the same figure share one family-wide total and are counted once. Performance lines are what a public pension plan reports for its own interest in that fund, net, on the plan's cash flows and valuation date; they are not the general partner's figures.
