Investors cheering the planned $130-billion merger of Dow Chemical and DuPont should raise a glass to the lawyers. Last week's deal might never have come together without rarely exploited fine print in the US tax code that should avoid any tax on capital gains.
Dow and DuPont are planning a merger of equals followed by a break-up into three separate listed companies. Generally, the Internal Revenue Service (IRS) discourages such multi-step deals. When half or more of a unit's shares change hands in association with a spin-off, the parent company or shareholders can end up with a big bill from Uncle Sam. Dow shareholders taking a 50 per cent stake in former DuPont assets as a result of the merger and split plan could trigger a tax liability for DuPont or its owners, and vice versa.
The relevant section of the US tax code also gave the world the reverse Morris Trust, a convoluted structure companies use to avoid taxes when planning a spin-off followed by a prearranged merger. Dow and DuPont, though, have carved out an even less common way to sidestep the IRS.

US companies engage in all manner of tax-saving contortions. Pfizer is expected to save billions of dollars by moving its tax domicile overseas as part of its $160-billion merger with Botox maker Allergan, for example. Known as inversions, such deals have drawn ire from politicians and the public.
For Dow and DuPont, though, the strategic rationale of the whole plan is sound. And two US industrial blue-chips with essentially the same market value are bound to have common shareholders. The tax liability is also deferred until shares are sold, not removed altogether. Rather than being cagey, fitting the deal into byzantine tax rules looks like clever opportunism.
