DETROIT - Mary Barra, General Motors Co's?new chief executive officer and the auto industry's first female CEO, will be paid up to $4.4 million in cash and stock compensation this year, GM disclosed in a federal filing on Friday.

The package for Barra, who assumed her new role on Wednesday, does not include what she and other executives will receive under the long-term compensation plan, which is subject to shareholder approval in June. GM will disclose those details in April.

The No 1 US automaker revealed in documents filed with the US Securities and Exchange Commission that Barra, 52, will receive an annual cash base salary of $1.6 million. She also will be eligible for $2.8 million under the company's short-term incentive plan.

GM has not yet disclosed what former CEO Dan Akerson was paid in 2013, but the previous year he was paid $11.1 million, including $1.7 million in cash and $7.3 million in stock and other incentives. The 2012 figure also reflected $2 million in restricted stock units that he received in 2011.

GM also said on Friday that new President Dan Ammann, the former chief financial officer, will be paid just over $2 million. The cash base salary is $900,000 and he is eligible for $1.125 million under the short-term plan, according to the SEC documents.

Ammann's successor as CFO, Chuck Stevens, will receive an annual cash base salary of $700,000 and will be eligible for $875,000 under the short-term plan, according to the SEC documents.

All three executives also will participate in the benefits plan currently available to company executives.

GM also disclosed that Akerson and former Vice-Chairman Steve Girsky will remain as senior advisers to the company on an interim basis. Girsky remains on GM's board.

Akerson will receive an annual cash base salary of $1.7 million and be eligible to receive $2.975 million under the short-term plan, while Girsky will be paid a base salary of $600,000 and be eligible to receive $750,000 under the short-term plan, according to the SEC documents.

GM expects both men will be employed less than a year and their salary will be paid on a prorated basis as will any payment to Akerson under the short-term plan, according to the SEC documents.
