Stated investment criteria
What ClearSky says it buys
Read from ClearSky’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.
A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. The team figure counts the people the firm shows on one team page, so it is a floor rather than a headcount: firms that split their team across tabs or load it in pages will read low. Nothing here is a commitment by ClearSky to consider any particular business, and nothing on this page is represented as being for sale.
Regulatory record
How ClearSky is registered
From this firm's Form ADV, the annual filing every registered and exempt investment adviser makes to the SEC.
| Adviser status | Exempt reporting adviser |
| Regulatory assets under management | Not reported by an ERA |
| Private funds advised | 5 · $716m gross |
| SEC adviser number | CRD 326951 |
An exempt reporting adviser is not required to report regulatory assets under management, so the blank above means the question was not asked rather than that the answer is unknown. Where a figure exists it is the gross asset value of the private funds the firm advises, which is a different and usually larger measure.
