(Bloomberg) -- Investors in the Credit Suisse Group AG funds that invested in assets sourced by Greensill Capital may face a further $190 million loss on their holdings.

A discount of roughly 7% will be applied to notes on a book of around $2.8 billion loans held in the funds, adding to potential losses stemming from troubled borrowers such as SoftBank Group Corp.-backed Katerra, U.S. coal miner Bluestone Resources Inc. and Sanjeev Gupta’s GFG Alliance, according to a statement from the Swiss lender.

The bank didn’t identify the creditors that may not fully repay the loans. It hired an advisory firm to assess the creditworthiness of the underlying borrowers, according to the statement.

Greensill filed for insolvency in March as it couldn’t roll over insurance coverage for some of the products it sourced and packaged. Credit Suisse, citing valuation concerns, eventually moved to wind down a $10 billion group of supply chain finance funds that purchased those loans.

The bank has since returned a total of $4.8 billion to investors. Valuation on the $2.3 billion notes linked to Katerra, Bluestone and GFG remain uncertain, Credit Suisse said in the statement.
