The short version

Derek Leck is listed as an executive officer on 1 SEC Form D filing by 1 issuer in Dec 2011: American Industrial Partners Capital Fund V, L.P. (New York, NY — pooled investment fund — 2011; $700M reported sold to 49 investors).

What this means One deal on file with the SEC, filed Dec 2011. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside AIPCF V, LLC (1 shared filing, management entity), Ben DeRosa (1 shared filing), Daniel Davis (1 shared filing), Dino Cusumano (1 shared filing), Eric Baroyan (1 shared filing) and 9 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Derek. Each name links to their own page.

The issuer belongs to the sponsor group American Industrial (7 issuers, $2.5B reported sold, 2011–2026).

What this means A sponsor group is one team that sets up a new company for each deal. American Industrial has 7 companies on file and $2.5B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 7 court cases matching the name, 13 bankruptcy cases matching the name listed in Key records below.

What this means 20 records came back, including 5 court cases still open — open cases can take years and cost money. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

No differences found between the public filings we have for Derek Leck (compared 1 filing on Oct 24, 2026).

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

5. Money to insiders

1 of 1 offering reports sales commissions totalling $4,025,000; 0 report finder's fees; 0 report proceeds to related persons.

Offering (latest filing)	Sales commissions	Finder's fees	To insiders	Paid to sell it	Source
Dec 29, 2011 D American Industrial Partners Capital Fund V, L.P. File 021-170942	$4,025,000	$0	$0	MVision Private Equity Advisers USA LLC BrokerCheck CRD 122242 ↗ via MVision Private Equity Advisers USA LLC (CRD 122242 ↗)	EDGAR ↗

How this is counted

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

Counted across every filing this person is listed on (latest filing per offering, per issuer).
