Top executives at Riverstone Holdings LLC, one of the world's largest energy investment firms, have ceded more than $300 million of profits they made from investments before the oil bust erased those gains, according to securities filings and people familiar with the matter.

The money is related to an incentive formula employed at private-equity firms in which executives earn a cut of profits above a certain threshold for each fund.

In Riverstone's case, profits in some of its funds shriveled after U.S. oil prices plunged to below $27 a barrel earlier this year from more than $100 in mid-2014. That decline reduced the value of some companies owned by Riverstone, eliminating paper gains and requiring some executives to return profits in a so-called clawback.

David Leuschen and Pierre Lapeyre Jr., who founded Riverstone and remain its majority owners, are the primary recipients of its portion of deal profits, known as carried interest. Through a spokesman, Messrs. Leuschen and Lapeyre declined to comment.

While most private-equity funds usually keep details of their fund performance and structure private, industry executives say clawbacks are rare. Most firms want to avoid having to recall payments made to executives, some of whom may have left the firm or already spent the cash.

What's more, diversified private-equity firms make investments across a number of sectors that balance a fund's results; losses on one deal can be offset by profits on another.

But funds that focus on oil and gas, which exploded in popularity since the start of the shale boom, have become particularly vulnerable to big swings in performance because their profits are highly susceptible to changes in energy prices.

David Fann, chief executive of TorreyCove Capital Partners LLC, which vets private funds for investors, said clawbacks in energy funds are becoming more common as low oil prices continue to pummel investments made when prices were much higher. "It's the new normal for investors in oil funds," he said. "They're realizing the challenges of oil volatility."

A clawback is a feature of private-equity funds intended to assure investors they will earn a minimum return, often 8%, before the fund managers take their share of the profits—and that fund investors won't be left holding the bag if investments lose value after fund managers cash out of early successful deals.

The mechanics vary from firm to firm, but many pay out deal profits as they are earned and don't repay them until the end of a fund's life, which is often 10 years or more.

It's unclear how much, if any, cash Riverstone executives personally have had to surrender back to the fund. They could hold off until the fund is liquidated, hoping that oil prices bounce back and their debts are erased. The firm typically holds a portion of its deal profits in escrow to avoid having to ask executives to repay large sums should investments lose value, according to a person familiar with the matter.

Riverstone isn't alone in having profits slip away in the oil bust. Private investment funds focused on oil and gas lost roughly 22% of their value in 2015, a crushing year that has negated several prior years of gains, according to investment adviser Cambridge Associates LLC. For the five years ended Dec. 31, such funds have an annualized loss of 0.06%, after fees, Cambridge says.

Riverstone was founded in 2000 by the two former Goldman Sachs Group Inc. energy bankers as the shale boom was taking off. One of the New York investment firm's early funds, launched in 2002, produced annualized profits of about 55% after fees, according to public pension records.

Money poured into subsequent funds from pensions and other institutional investors eager to get in on the shale boom and renewable energy, one of Riverstone's other specialties. Riverstone became a landing spot for former Goldman bankers as well as former oil company CEOs from firms like Anadarko Petroleum Corp. and BP PLC. Even as crashing oil prices rippled through its holdings, Riverstone has continued to raise billions of dollars for new funds. Riverstone has raised $34.2 billion, since its inception, including some $7 billion since oil prices crashed.

The firm initially partnered with Carlyle Group LP, which helped the upstart raise money and handle back-office functions in exchange for a stake in Riverstone's funds. That partnership lasted for several funds before Riverstone struck out on its own for a $7.7-billion fund it raised in 2013.

Carlyle said in a securities filing that as of June 30 it had set aside $76 million in gains it owes back to three funds it manages alongside Riverstone based on the investment pools' present value.

Each of the three Riverstone funds that Carlyle says are subject to the clawback remained profitable for investors as of June 30 but have fallen below the minimum level of profitability that entitles the firms to a cut of the gains. They are the only of Carlyle's 34 funds in clawback, company filings show.

When Carlyle reported second-quarter results last week, analysts asked executives why another of its funds, which had gained enough for the firm and its shareholders to start taking their cut, hadn't started paying out. Carlyle's executives said they wanted to ensure the profits were permanent lest they wind up having to return money.

"Investors aren't happy with clawback," said Carlyle co-CEO David Rubenstein, "but the professionals in our firm are even less happy when we have to claw back."
