TE for New Canada-U.S. Protocol Should Eliminate an Old Uncertainty

By Philip D. Morrison, Esq. Deloitte Tax LLP, Washington, DC

Treasury's Technical Explanations (TEs) to the tax treaties and protocols it negotiates and sends to the Senate for ratification, while designated “official guidance,” are never amended or updated. As pointed out in a prior commentary,1 they are more in the nature of legislative history, locked in stone once written and released, and not susceptible of amendment.

Every so often, however, Treasury has the opportunity for a “do-over.” When a new protocol amends an old treaty article but preserves language from (or uses very similar language to) the old article, the TE for the new protocol provides a chance for Treasury to clear up any ambiguities or uncertainties that have arisen with respect to the old language. One such opportunity that Treasury should grasp when it prepares its TE for the fifth Protocol to the Canada-U.S. Treaty2 (the “new Protocol”) is to clarify the meaning of “substantial and regular trading” and “primarily and regularly traded” as those terms are used in Article XXIXA (Limitation on Benefits) (LOB).

The third Protocol to the Canada-U.S. Treaty3 added a unilateral LOB, aimed at preventing non-qualifying persons from enjoying U.S. benefits. Like all U.S. treaty LOBs at that time and since, that LOB provided that a publicly-traded Canadian corporation could be a qualified person. Also like LOBs of the same era, to be publicly-traded a corporation had to have “substantial and regular trading” of its shares on a recognized stock exchange. Unlike virtually every other treaty of that era, however, no guidance was provided with respect to the meaning of “substantial and regular trading.” Neither the third Protocol itself nor any of the accompanying documents, including the TE, defined what “substantial and regular trading” of a public company's shares means.

Like most other treaties, the Canada-U.S. Treaty provides a catch-all provision for undefined terms. Under Article III(2), unless the context otherwise requires (or the Competent Authorities otherwise agree), an undefined term is generally defined by reference to the tax law of the source country. Thus, for purposes of defining “substantial and regular trading” for purposes of the LOB added by the third Protocol (applicable to U.S.-source income), one must look to U.S. tax law.

The most sensible place to look for such a definition is in Regs. §1.884-5. That section provides the anti-treaty shopping rules implementing and interpreting the anti-treaty shopping rule of §884(e), the branch tax's self-contained LOB. That provision is designed to do precisely the same thing that the treaty LOB is intended to do -- prevent treaty shopping.

While “substantial and regular trading” with respect to a public corporation's stock is not defined in Regs. §1.884-5, “regularly traded” is. Under Regs. §1.884-5(d)(4), stock is generally considered to be regularly traded if: (A) stock representing 80% or more of the vote and value is listed on an established securities market; and (B)(1) there are trades on more than 60 days in a year; and (B)(2) there is 10% turnover during the year. Classes of stock that are listed on a U.S. exchange are deemed to meet the 10% annual turnover requirement if the stock is regularly quoted by brokers or dealers making a market in the stock. These rules are similar, but for the market maker presumption to satisfy the turnover requirement, to rules spelled out in other treaties or their accompanying documents or TEs enacted both before and after the third Protocol.4

Unlike treaties, however, Regs. §1.884-5(d)(4)(iii) provides that closely held classes of stock cannot ever be treated as meeting the trading requirements of (B)(1) and (B)(2), above, whether, as a factual matter, they do or not. “Closely held” generally means that non-qualifying shareholders, each of whom owns 5% or more of the value of a class of stock (after applying a related person rule), own 50% or more of the class for more than 30 days during a taxable year.

It is not entirely clear whether this closely-held rule of the branch tax regulation should apply as part of the domestic law one should apply under Article III(2) to define the third Protocol's term “substantial and regular trading.” On the one hand, while most other U.S. treaties' LOB provisions use some variation of the branch tax's method for computing “regular trading,” no other U.S. treaty LOB provision defines “substantial and regular trading” to include the branch tax's closely-held rule. In addition, the 1996 and 2006 U.S. Model Treaty TEs both provide that “regularly traded” as used in the LOB provision for public companies shall, pursuant to Article 3(2), have the meaning ascribed by the branch tax regulations, with the exception of the closely-held rule. If, consistently from 1996 to at least 2006, Treasury interprets the words “regularly traded” to include the branch tax rules generally but without reference to the closely-held rule, it might be strained for the government to maintain that the very same words in 1995 (the third Protocol to the Canada-U.S. Treaty) meant something different (i.e., the branch tax rules including the closely-held rule).

On the other hand, it is evident from treaties both before and after the third Protocol to the Canada-U.S. Treaty, and from the Model TEs, that Treasury and its treaty partners knew how to define “regularly traded” to not include the branch tax rules, or at least the branch tax closely-held rule, when they wanted to. Normal precepts of statutory interpretation would indicate that, if they neglected to say something in one case that in multiple other cases they clearly said, perhaps it is because they intended the omission in that one case. Further, as a policy matter, it is easy to construct an argument as to why Treasury might have wished the closely-held rule to apply. If a Saudi prince (the archetype of a treaty shopper) owns 80% of a public Canadian company that meets the trading test by lots of turnover in the remaining 20% of its shares, is that a sympathetic, non-treaty-shopping case?

However one resolves this debate, it is difficult to say there is an inarguably correct answer. Unfortunately, the new Protocol, if adopted, will insert into the Canada-U.S. Treaty a new LOB article that, so far, has the same lack of clarity. Indeed, because the terms used in the new Protocol are “primarily and regularly traded,” the identical words in the branch tax, it could be argued that there is even a slightly greater need than before for clarity. It is imperative, therefore, that the TE being written for the new Protocol make clear, as the Model TEs do, that the branch tax closely-held rule does not apply. While an explanation in the TE for the new Protocol would not entirely eliminate any question regarding the meaning of “regular trading” for years controlled by the third Protocol, if Treasury took the opportunity in the TE to note that having no closely-held rule has been a consistent policy since at least the 1992 signing of the Netherlands-U.S. treaty, it would be very helpful in resolving such a question regarding the application of the third Protocol.
