IBM's Rometty: Watson financials don't need to be broken out

IBM has no plans to break out Watson financials for investors, said CEO Ginny Rometty.

The cognitive system that first became known to the public in 2011 when it won at "Jeopardy," is not an independent business but something that will be used across IBM's products, Rometty said on Wednesday at the Code Conference in Rancho Palos Verdes, California.

"If it's digital, it will be cognitive," Rometty said. She said there's no value in disclosing Watson financials while "I nurture and grow it."

IBM is using Watson to understand complex problems with mounds of unstructured data and aiming to present answers.

CNBC's parent NBCUniversal is an investor in Recode's parent Vox, and the companies have a content-sharing arrangement.
