(Reuters) - Boeing Co's board on Friday unveiled new performance metrics for executives tied to product safety and quality, following fatal 737 MAX crashes related to design defects and as it wrestles with repairs to flawed 787 Dreamliner jets. The planemaker said its Chief Executive Officer David Calhoun had a take-home pay of $269,231 in 2020 after he agreed to forgo his pay and incentive bonus in March last year as the COVID-19 pandemic set in, according to a proxy filing.
