The short version

Klingenstein Fields is a sponsor group of 6 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, similar issuer names; automatic match from the filings), filing 18 Form D filings between Mar 2010 and Aug 2023.

What this means One team, 6 deal companies, about 13 years of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $100.4M to 197 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (5), Investing (1). Issuers are based in NY (6).

What this means $100.4M raised across the group, about $510K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: James W. Fields (6 issuers, executive officer), Kenneth D. Pollinger (3 issuers, executive officer), Jonathan Roberts (2 issuers, executive officer), W. Klingenstein, Fields & Co., L.L.C. (2 issuers, executive officer, entity), Fields James (1 issuer, executive officer) and 8 more.

What this means The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 0 new offerings in the last 12 months; latest filing Aug 21, 2023.

What this means No new raise filed in the past year.

Adviser registration (Form ADV) on record: KLINGENSTEIN FIELDS ADVISORS.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY), property records (NYC, FL, IL and TX counties) — none found.

What this means Nothing turned up where we looked (4 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 18 public filings for Klingenstein Fields and found 21 differences, 7 worth asking the sponsor about: Investor count went down between filings; Klingenstein Fields includes 4 deals that stopped filing before reaching their target; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

Worth asking · Dec 15, 2010 – Jun 22, 2012

Investor count went down between filings — Klingenstein Fields Asia Fund, LP

The Dec 15, 2010 filing reports 45 investors; the Jun 22, 2012 Form D/A reports 9 investors.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Klingenstein Fields includes 4 deals that stopped filing before reaching their target

(last filing Oct 30, 2018; $17,287,500 sold of $50,000,000); Klingenstein Fields Global Fund LP (last filing Nov 13, 2015; $4,240,000 sold of $50,000,000); Klingenstein Fields Alpine Partners, LLC (last filing Jun 25, 2012; $22,000,000 sold of $50,000,000).

Form D filed 1,007 days after the first sale — Klingenstein Fields Global Fund LP

The filing says the first sale was Jun 1, 2007. The Form D was filed Mar 4, 2010 — 1,007 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 992 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

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.
