Aldergate Capital Closes a $1.2 Billion Direct-Lending Fund as Scrutiny of Private Marks Grows
The mid-market credit manager’s largest fund yet lands as investors press the industry on a harder question: how the loans on these books are valued when almost none of them trade.

NEW YORK — Aldergate Capital, a mid-market private credit manager, said Friday it had closed its fourth direct-lending fund with $1.2 billion in committed capital, its largest to date. The fund will make senior secured loans to U.S. companies with roughly $10 million to $75 million in annual earnings — the middle-market borrowers that have increasingly turned to non-bank lenders as banks retrenched from leveraged lending.
The raise itself is unremarkable in a sector that has expanded to well over a trillion dollars in assets. What has changed is the set of questions being asked of managers like Aldergate at the moment they raise money, and most of them come down to a single issue: valuation.
Private credit loans, by design, do not trade on an open market. That is much of their appeal to borrowers, who get certainty and speed, and to investors, who are spared the mark-to-market volatility of syndicated debt. But it also means the value of a fund’s portfolio at any given quarter is not observed in a market — it is estimated by the manager, subject to the review of an auditor and, in most cases, a third-party valuation firm.
That estimation is where the current scrutiny is concentrated. When a borrower’s performance deteriorates, a manager has discretion over how quickly and how far to mark the loan down. Two funds holding economically similar loans can carry them at materially different values, and an investor comparing reported returns across managers is comparing numbers produced under different assumptions.
Aldergate marks its portfolio quarterly and uses an independent valuation provider, according to a person familiar with the fund’s terms, who described the arrangement as consistent with institutional norms. The firm declined to make an executive available for an interview and did not disclose the identity of the valuation provider or the inputs it uses.
That reticence is itself typical, and it is the crux of the disclosure debate. Regulators and large limited partners have pushed for more standardized reporting on how private-credit marks are derived, how many portfolio loans are on non-accrual, and how valuations move relative to the public credit indexes that track comparable risk. The Securities and Exchange Commission’s private-fund reforms sought to expand the quarterly information managers must provide, though the scope of those rules has been contested in court and remains narrower than some investors wanted.
For an investor in Aldergate’s new fund, the practical exposure is straightforward to state and hard to monitor. The headline return will be a function of marks the manager controls, on loans that will not be tested against a market price unless a borrower defaults or the fund sells. In a benign credit environment those marks are rarely challenged. It is when defaults rise — as broader household and corporate credit data have begun to suggest they may — that the gap between a carried value and a realizable one becomes visible.
Aldergate’s prior fund, raised in 2023, has not had a full cycle to be tested that way. Neither has most of the capital that has flooded into direct lending over the past three years. That, more than the size of any single close, is what the industry’s investors are now weighing.
