Boeing's sacked chief executive officer Dennis Muilenburg is leaving the company with $62m in compensation and pension benefits.

But the company said he will receive no severance pay in the wake of the 737 MAX crisis. 

Dennis Muilenburg was fired from the job in December as Boeing failed to contain the fallout from a pair of fatal crashes that halted output of the company's bestselling 737 MAX jetliner and tarnished its reputation with airlines and regulators. 

The compensation figures were disclosed in a regulatory filing on Friday night during a difficult week for Boeing when it also released hundreds of internal messages.

These two major issues hang over the company before new CEO David Calhoun starts today. 

The messages contained harshly critical comments about the development of the 737 MAX, including one that said the plane was "designed by clowns who in turn are supervised by monkeys." 

The 737 MAX has been grounded since March following the second of two crashes that together killed 346 people within a span of five months. 

The MAX has been grounded since the second crash in March. 

Speculation that Muilenburg would be fired had been circulating in the industry for months, intensifying in October when the board stripped him of his chairman's title - although he had also twice won expressions of confidence from Calhoun, Boeing's board chairman. 

A turnaround veteran and former General Electric executive who has led several companies in crisis, Calhoun will receive a base salary at an annual rate of $1.4m and is eligible for $26.5m in long-term incentive compensation, Boeing said in a filing. 

Boeing said in November Muilenburg had volunteered to give up his 2019 bonus and stock awards. For 2018, his bonus and equity awards amounted to some $20m, according to filings. 

In addition to the $62m in compensation and pension benefits, Muilenburg holds stock options that vested in 2013, Boeing said. 

They would be worth $18.5m at the closing price on Friday. 

"Upon his departure, Dennis received the benefits to which he was contractually entitled and he did not receive any severance pay or a 2019 annual bonus," Boeing said in a statement.
