General Electric Co. is discussing the sale of parts of its finance business, including the $74 billion U.S. commercial-lending unit, with potential buyers including Blackstone Group LP, Mitsubishi UFJ Financial Group Inc. and Wells Fargo & Co., said people with knowledge of the matter.

Also interested is Apollo Global Management, said the sources, asking not to be identified discussing private information.

Talks are at an early stage and no sale is imminent, the sources cautioned. GE thinks it can sell the majority of the financial assets by the end of 2015, one person said, ahead of its stated goal of the end of next year.
