Rometty's base salary is set at $1.5 million, but that's only 10% of her compensation.
She received an annual incentive of $3.9 million for her performance in 2012, partly due to the fact that her leadership allowed IBM (IBM) to return "significant value" to shareholders. Big Blue boosted its dividend by 13% in 2012 and bought back $12 billion in stock, according to a regulatory filing.
