Flows (revenues, income, cash, distributions, repurchases) are shown for the period the issuer reported them in, which may be a quarter, a year-to-date span or a full year; “a year earlier” compares only periods of the same length. A vehicle that does not tag a figure in XBRL will not show it here even if the PDF discloses it.

If you have real money in this, do not decide it alone.

We can tell you what the filings say. What we cannot tell you is what it means for your particular position, your tax situation and the rest of your portfolio, and anyone who does that from a web page without knowing your circumstances is guessing. With money in a non-traded BDC whose repurchases are capped each quarter, that is the part that actually matters.

Get matched with a fiduciary adviser

Answer a few questions

A short questionnaire about your assets and goals, then introductions to advisers who are held to a fiduciary standard, meaning they are required to put your interests first. Free to you. No money moves and nothing is bought.

What we don't like: you are handing over your contact details and advisers will get in touch, so expect calls. We have not vetted any individual adviser and we are not endorsing one. Treat the introduction as a starting point, not a recommendation.

We are paid a referral fee if you complete the questionnaire, at no cost to you. We are not paid by, and take nothing from, any platform reviewed on this site.

No forensic read of this vehicle yet. When a filing changes something for holders — a tender offer, a repurchase cap, a NAV reset, a distribution cut — the read goes here.
