Akerson's replacement, Mary Barra, received compensation worth just over $5.2 million last year in her role as global product development chief, up 12 percent from 2012. GM already has disclosed that she'll get a package this year that the company values at $14.4 million, including a long-term incentive target of $10 million.
The company disclosed the pay packages Friday in its annual proxy filed with the U.S. Securities and Exchange Commission.

GM's net income last year was $3.8 billion, down 22 percent from $4.9 billion in 2012. The company said in its filing that under Akerson, 65, GM passed many milestones last year. It reported its fourth straight year of profitability and revenue growth, and was freed from U.S. government ownership.
GM also grew further in China, cut losses in Europe, raised quality and launched 36 new vehicles worldwide.
