On November 19, 2015, Treasury released Notice 2015-79 (the “Notice”). The Notice represents Treasury’s most recent response to the second wave of inversions, i.e., transactions in which US corporations become subsidiaries of foreign corporations without a meaningful change in their underlying business or in the location of their corporate headquarters. It follows on the heels of the announcement that Pfizer Inc. is considering a merger with Allergan PLC, an inverted Irish company, and supplements Notice 2014-52 from September 2014. Unfortunately, just like Notice 2014-52, the Notice is unlikely to stem the tide, and is even unlikely to stop Pfizer/Allergan. For that, stronger executive and legislative action is needed. To understand the issues, it is important to know about the history of inversions and the three reasons that drive them.
