Cigna CEO David Cordani made $43.9 million in 2017, according to a federal securities filing. That amount reflects the stock awards and options that Cordani actually cashed out.

The big picture: Cordani was in the spotlight a lot last year. He broke off the health insurer's merger with Anthem after feuds plagued both sides. Cigna is suing Anthem for almost $15 billion "as a result of the failed merger process," and a trial for the case is scheduled for 2019.

Buried in the weeds: The Securities and Exchange Commission now requires publicly traded companies to report CEO pay ratios, which show how much the average company employee makes compared with the CEO.

• The median annual compensation of a Cigna employee was $63,010 in 2017.
• Cigna calculated the CEO pay ratio at 279:1 (for every $1 the average worker makes, Cordani gets $279).

Yes, but: That's not entirely accurate. Based on SEC rules, the reported ratio is based on the estimated fair value of Cordani's stock instead of the actual realized value.

• Using Cordani's $43.9 million compensation total, Cigna's CEO pay ratio was 697:1.
