June 3 (Reuters) - Shares in Partners Group AG fell as much as 13% on Wednesday after a Bloomberg report said the Swiss private markets firm had capped withdrawals in one of its evergreen private equity funds following a surge in redemption requests.

The report said the company is limiting redemptions in its $8.6 billion Global Value SICAV fund to 5% of net asset value per quarter after requests climbed to about 9.8% in the second quarter, according to a letter to investors.

Partners Group confirms to Reuters that it is capping withdrawals on the fund.
