A trickle has turned into a torrent. Burger King’s announcement last week that it would buy Canadian donut darling, Tim Horton’s, and then move the merged corporation to Canada represents the 13th such deal announced this year. Most companies pursuing these “corporate inversions” have abandoned America for the express purpose of lowering their U.S. tax bills.

This year’s baker’s dozen of tax dodgers join 76 firms that have shed their U.S. identities and re-registered abroad since 1983, with 47 adopting inversions in the last decade alone, according to a May 2014 report by the Congressional Research Service.

Firms that refuse to pay taxes to support the public services and people that have helped their businesses thrive defend their actions by saying they are simply responding to their financial obligations to shareholders to lower company costs and boost corporate profits. Does that passion for cutting costs carry over to the pay of company CEOs?

We looked at the pay of the 32 companies that have undergone foreign corporate inversions and continue to report their executive compensation in their annual proxy statements filed with the U.S. Securities and Exchange Commission (SEC). We counted salary, bonus, non-equity compensation, perks (including personal use of corporate jets, country club fees, and personal financial service planning), as well as the value of stock grants vested and stock options cashed in. We did not include the theoretical value of new stock grants or stock options.

The CEOs of these firms collectively took home $439 million in 2013, an average of $13.7 million per CEO. Eight of the CEOs pocketed more than $20 million each, and Stephen Luczo, CEO of Seagate Technology, took home nearly $46 million last year. Seagate is a cloud-based data storage firm that operates out of California but is incorporated in Ireland.

These CEOs grew their companies with the protection of U.S. laws and with public investment in education, infrastructure, and basic research. But now that they’re successful, they no longer want to support the system that allowed and supported their growth.

Sen. Carl Levin (D-MI) and Rep. Sander Levin (D-MI) have introduced The Stop Corporate Inversions Act of 2014. The legislation would impose a two-year moratorium on inversions and change the rules governing them. Under the new rules, companies would have to be managed from outside the United States and give up ownership control to foreign partners in order to be considered a foreign company for U.S. tax purposes. U.S. managers could not use the legal change to reduce their corporation’s tax bill while maintaining their American lifestyle and control over their company. The Joint Committee on Taxation estimates this legislation would save the U.S. Treasury $19.5 billion over the next decade.
