The word "ironic" may be used too much, but how else do you describe Medtronic moving its headquarters to Ireland so that it will have more capital to invest in the U.S.?
Buying Covidien PLC for $42.9 billion turned out to be Medtronic's solution to one of its most vexing problems: How does the global medical device maker use its "trapped cash," the more than $20 billion in earnings from its non-U.S. subsidiaries, without paying a higher U.S. tax rate?
It's actually trapped by choice, of course, as leaving capital offshore is one of the ways that big companies manage to pay far less in income taxes than the statutory federal rate. Companies would argue that the U.S. tax bite leaves them no real choice.
Medtronic has this trapped-cash problem because it has been quite skilled at keeping down its tax bill. Only a handful of companies in its industry have a lower effective tax rate than Medtronic's, about 17.3 percent of pretax income.
The average tax expense for a group of about two dozen big medical-device companies is about 25 percent, according to a May study by the investment firm Morgan Stanley.
One of the ways big U.S. medical device companies pay taxes well below the 35 percent statutory rate is to find ways to incur more of their costs (and thus lower profit) in their home country, where the tax rate is higher. Medtronic is fairly typical in that it gets about 45 percent of its sales from abroad but about 55 percent of pretax profits.
U.S. companies are generally taxed in the U.S. on the money they make anywhere, but if the money made abroad isn't brought home in the form of dividends or distributions from offshore subsidiaries, it's not taxed.
More importantly, those earnings don't necessarily create a tax liability assuming taxes will get paid someday, even though it seems obvious that those profits eventually have to be brought home to pay as dividends to the shareholders who own the company.
