The 26 corporations cited in this year’s study is an increase of one from last year, and the institute says that seven corporations — Boeing, Chesapeake Energy, Ford, International Paper, Marsh & McLennan, Motorola Mobility Holdings, and Motorola Solutions — made the list both years.
Boeing, for instance, is a heavy user of the research credit, while AT&T has relied on the write-off provision known as accelerated depreciation. Chesapeake Energy, meanwhile, has leaned on credits for drilling.
Companies cited in the study have questioned the methodology the group used, and also said that their use of certain tax provisions has allowed them to create jobs and investment in the U.S. economy.
The institute used, among other things, salary, bonuses, non-equity compensation and stock values to calculate a chief executive’s earnings.
It used Securities and Exchange Commission filings for how much a company paid in taxes, which don’t include what is paid to state, local or foreign governments and also, some analysts say, is not the best method of tracking exactly what a company pays to the federal government.
