Wells Fargo & Co. said on Friday that it has recorded a $39 million loss tied to some complex debt that has lost value and which is held by its money market mutual funds, Reuters reported.

In its annual report filed with the U.S. Securities and Exchange Commission, Wells Fargo said the loss relates to a capital support agreement for up to $130 million related to one structured investment vehicle held by some money funds that invest in non-government securities.

The San Francisco-based bank said it entered the agreement about a month ago to preserve the “triple-A” investment ratings for some of the funds. Wells Fargo said the $39 million liability reflects the guarantee it provided. The bank said it has about $106 billion of assets in money market mutual funds.

A Wells Fargo spokeswoman had no immediate comment.

Wells Fargo joins several other companies with mutual fund operations to bail out or support money funds stuck with debt that became illiquid or quickly lost value, including Bank of America Corp., Janus Capital Group Inc., Legg Mason Inc. and Wachovia Corp.
