Bloomberg News is reporting that Virginia “Ginni” Rometty's salary almost doubled to $1.5 million after she was promoted to CEO of IBM, the world's largest computer-services provider, at the start of this year.

Rometty - who was formerly IBM's chief marketing executive making $800,000 a year - is the first female CEO in the company’s 100-year history.

Her cash-incentive target for the year is $3.5 million, compared with the $1.47 million she received for 2011.

New York-based IBM employs about 10,000 people at its campus in Research Triangle Park.

The top boss at Blue Cross and Blue Shield of North Carolina made $1.87 million last year, less half what his predecessor earned during the prior year.

The state's largest health insurer disclosed the pay package for Brad Wilson, who took over as CEO last February, in its annual report with the N.C. Department of Insurance.

Bob Greczyn made $4.08 million in 2009, his last full year as CEO.

Some of the difference is related to their tenure as CEO -- Greczyn had a higher base salary and bigger potential bonus after more than a decade running the company, said chief financial Gerald Petkau. And some of Wilson's total pay package is tied to longer-term incentives, which he will  be in line to receive in coming years.
