Key Points:
• Different corporate tax rates among countries can distort the global M&A market.
• Frequent regulatory changes to close “loop holes” that should be done legislatively impede investment by
creating uncertainty in corporate boardrooms.

While M&As rarely are undertaken solely for potential tax benefits, tax laws can sometimes distort the underlying
economic motives for doing deals. Tax laws (and regulations) distort corporate decision making. Current U.S.
corporate tax rates, the highest in the world, encourage U.S. corporations to relocate to countries offering
substantially more favorable tax rates. Corporations viewing taxes as any other operating expense have a fiduciary
responsibility to shareholders to pare costs to remain competitive.
According to the US Congressional Budget Office “The current (U.S.) tax system provides incentives for U.S.
firms to locate their production facilities in countries with low taxes…. (and) reduce economic efficiency …because
the firms are not allocating resources to their most productive use. Those responses also reduce the income of
shareholders and employees in the United States, and they lead to a loss of federal tax revenue…in the long run,
total compensation for U.S. workers is lower, and employment may be concentrated in different industries and
regions (even though total employment is not significantly affected.”1
On April 5, 2016, the Treasury announced new regulations, more far reaching than previous regulatory changes
in 2014 and 2015, aimed at “serial inverters” (i.e., companies that have grown through a succession of acquisitions
resulting in inversions). The new regulations consisted of two parts. First, the government would disregard U.S.
assets acquired by a foreign firm over the previous three years in determining the size of the firm. Second, the
government would have more leeway in determining whether moving cash within a consolidated company would be
viewed as intercompany lending or simply a transfer of equity. The government’s new rules would apply to all deals
that close after April 6, 2016 and all intercompany loans after that date. Companies that have already closed
inversion deals will be unaffected by the three-year rule, though transferring earnings from their U.S. subsidiaries to
their foreign parents could become less attractive.
The first part of the new rules deals with the determination of whether or not a firm engaging in a corporate
inversion can indeed be taxed at the lower foreign rate under current U.S. law. As of 2015, the U.S. Treasury
regulations applying to U.S. acquirers of foreign targets implementing corporate inversions focused on the
continuing percentage ownership stake of the acquirer’s shareholders following closing. If the continuing stake is
80% or more, earnings from U.S. operations are taxed at U.S. rates; between 60% and 80%, some portion of the
earnings are taxed at U.S. rates; below 60%, earnings are taxed at the foreign parent’s rate.
The second part is designed to reduce the attractiveness of what is often called “earnings stripping.” Foreign
parents can lend money to their U.S. subsidiary in a transaction that has no effect on the consolidated company’s
financial statements. However, interest paid by the subsidiary to the parent is tax deductible by the subsidiary,
reducing the subsidiary’s taxable income. This has the effect of transferring monies earned by the subsidiary to the
foreign parent to be counted as income to the parent and taxed at the parent’s lower tax rate. The new rules would
give the government more authority to treat those interest payments as dividend payments, which are not tax
deductible under U.S. law. The anti-earnings stripping rules aren’t just limited to inverted companies, but could hit
all companies based outside the U.S. that have operations inside the country.
What seems to have prompted the new regulations is one of the biggest takeovers in U.S. history. U.S.
based pharmaceutical giant Pfizer announced a planned merger with Dublin, Ireland based Allergan, the
maker of Botox, in late 2015. This megamerger would have been the biggest example an American
company shedding its U.S. corporate residence to lower its tax burden. From a business perspective, Pfizer
was the acquirer since it was clearly in control of the combined firms. Why? It was the larger of the two
firms with a market value exceeding $200 billion compared to Allergan’s $125 billion, its CEO retained that
position in the combined firms, the new board would be dominated by former Pfizer directors, and Allergan
shareholders received a premium for their shares. However, with Allergan designated as the acquirer for tax
