LONDON/NEW YORK (Reuters) - Financial information firm S&P Global ( SPGI ) is weighing options for its mobility business, including a full sale, three people with knowledge of the matter told Reuters.

The New York-listed group, known for its rating agency business and stock market indices, has spoken with advisers over plans for the business, which provides vehicle, market and consumer data for original equipment manufacturers, the people said.

Private equity firms in recent months have expressed interest in the unit, which is not viewed as a core part of S&P's strategy, the people said. The unit could be valued at more than $12 billion, two of the people said.

The sources, speaking on condition of anonymity because the talks are private, said that no decision had been made and a sale may not proceed.

A spokesperson for S&P Global ( SPGI ) said: "We do not comment on market speculation."

S&P in February said it is reviewing its portfolio of assets to focus on core areas of growth.
