AltStreet Analysis
·Generated from EDGAR primary sources
Lime Rock Partners X, L.P. is a Delaware-organized pooled investment fund filed by Lime Rock Partners GP X, L.P. as general partner, claiming Rule 506(b) and Section 3(c)(1) exemptions. The filing is pre-open with total amount sold, investor count, and first sale date not yet disclosed, and no minimum investment is stated on the form. No parent platform or sibling entities are currently matched in the database, though the entity name suggests it is part of a larger numbered Lime Rock Partners fund series.
This is a traditional closed-end private equity/energy fund structure using the common dual exemption pattern (506(b) for securities registration relief plus 3(c)(1) to limit investor count under the Investment Company Act), typical of institutional alternative investment vehicles. No minimum investment is disclosed on the filing itself, which is standard for this category since such terms are typically set in the limited partnership agreement rather than the public Form D.

Questions About Lime Rock Partners X, L.P.
