If the affiliate incurs intercompany debt from a parent corporation in a high tax jurisdiction such as Germany, disagreements with respect to the arm's-length interest rate could lead to double taxation. This problem dates back over a generation in particular with intercompany financing from U.S. parents to Canadian affiliates.
The issues for evaluating what is an arm's-length interest rate may be daunting in light of recent litigations as well as the new 46-page guidance from the OECD. The key to understanding these issues is to begin with a clear understanding of the relevant intercompany loan contracts. The new guidance emphasizes the accurate delineation of the intercompany transaction and has an extensive discussion on the controversy with respect to evaluating the appropriate credit rating.
A clear understanding of one's intercompany financing contracts address this accurate delineation issue, which allows any analysis to contrast the intercompany interest rate to the intercompany rate on the corresponding government bond with the difference being the credit spread implied by the intercompany contract.
Justifying this implied credit spread is the more difficult and controversial issue. The GE Capital Canada and Chevron Australia litigations highlighted the controversy with respect to estimating credit ratings. But even if consensus can be reached on the appropriate credit rating for the borrowing affiliate, volatile periods such as the current one as well as other periods of heightened credit spreads highlight the need for reliable and timely market information on corporate bond spreads.
Credit ratings are letter grades, which require translating into a numerical credit spread. The fallout from the COVID-19 crisis includes volatile credit spreads almost reaching what we witnessed after the collapse of Lehman Brothers in the fall of 2008.
A standard model for evaluating whether an intercompany interest rate is arm's-length can be seen to have two components — the intercompany contract and the credit rating of the related party borrower. Properly articulated intercompany contracts stipulate:
- The date of the loan;
- The currency of denomination;
- The term of the loan; and
- The interest rate.
As an example, let's assume that a Germany-based multinational extended a 20-year fixed interest rate intercompany loan of $1 billion to its U.S. affiliate on March 18, and tentatively decided that the interest rate should be 5%.
On that date, the interest rate on 20-year U.S. government bonds was 1.6%. If the appropriate credit spread was 3.4%, then the tentative decision to set the intercompany interest rate at 5% was consistent with the arm's-length standard.
The precise date of the intercompany loan matters as interest rates were volatile during this period. Interest rates on government bonds on March 18 were also lower than they were at the beginning of the year.
The term of the intercompany loan also matters as 10-year government bond rates were 1.2% and five-year government bond rates were 0.8% on March 18. As such, a clear intercompany contract should be drafted to address this accurate delineation of the transaction issue raised by the OECD guidance.
This contract should also be clear on the currency of denomination, which in our example is the U.S dollar and not the euro. This matters as the interest rate on German government bonds has been negative for much of the recent period.
Could the IRS argue that this 5% rate is too high? Could the German tax authorities argue that it is too low? Any reliance on the U.S. Department of the Treasury regulations Section 1.482-2(a) applicable federal rate safe-haven is misplaced for reasons similar to those I noted in early 2009:
For March 2020, the applicable federal rate safe-haven range was from 1.9% to 2.5%. As we shall note, the market interest rate was likely well above 2.5%. Given that the German tax authority is not obligated to honor a U.S. safe-haven range, the multinational in the example must evaluate what represents a market rate and then defend it to both tax authorities.
While the Internal Revenue Service might be tempted to argue for a lower interest rate, the German tax authority would be tempted to argue for a higher interest rate. Even if a consensus is reached on the difficult issue with respect to the credit rating, being able to translate this letter grade credit rating into a numerical credit spread requires reliable and timely data on credit spreads.
I have described the intercompany contract noting that the arm's-length rate equals the sum of 1.6% and the appropriate credit spread. The OECD guidance provides an extensive discussion of the issues involving the determination of an appropriate credit rating.
Standard & Poor's and Moody's Investors Service provide what are essentially letter grades for their estimate of the credit rating, which is based on the probability that the company will default on its loan as well as the expected cost to the lender in the event of default. Let's assume that the example multinational has a compelling case that this credit rating is Standard & Poor's BBB, which is equivalent to Moody's Baa2 rating.
As we entered 2020, market evidence suggested that corporate bonds with credit ratings of BBB would have credit spreads near 1.7%. The example intercompany contract has an implied credit spread that is twice what we saw earlier in the year. Miguel Faria-e-Castro, Julian Kozlowski and Mahdi Ebsim note the recent spike in credit spreads:
Their figures include credit spreads over this period for corporate bonds rated from BBB+ to BB- noting how spreads spiked during March 2020. While the IRS might view an implied credit spread equal to 3.4% as being above market rates, the German tax authorities could view it as too low in light of market conditions at the time of the intercompany loan.
We have witnessed spikes in credit spreads during other periods. My 2009 paper noted that while the credit spread for BBB rate bonds averaged 1.5% during the 1994 to 2008 period, this spread reached 5% by the end of 2008. Credit spreads were this high during the early years of the Great Depression and were somewhat elevated from 2000 to 2002.
Simon Gilchrist and Egon Zakrajšek published an informative paper on credit spreads and business cycles that provided their summary measure of credit spreads — the GZ credit spread, which was the average credit spread on senior unsecured bonds issued by nonfinancial firms.
The authors focus on the very high credit spreads during the 2007-2009 credit crisis but their evidence also shows a more modest spike in credit spreads for the 2000 to 2002 period. The following figure simply takes the difference between long-term corporate bonds rated BBB and the 20-year government bond rate to capture the credit spread for this particular credit rating.
This figure notes both the dramatic rise in this credit spread after the bankruptcy of Lehman Brothers as well as the more modest rise in credit spreads for the 2000 to 2002 period, which witnessed not only the 2001 recession but also the bankruptcies of companies such as Enron Corp. and Worldcom.
Two continuing litigations between the Canadian Revenue Agency and ConocoPhillips Canada Resources Corp. involve whether a 0.5% intercompany guarantee fee was appropriate.
Burlington Resources Finance Co. and Conoco both acquired Canadian oil fields with significant third-party debt with explicit guarantees extended to the lenders by the U.S. parent. Burlington's total borrowing from February 2001 to February 2002 was $3 billion, while Conoco's total borrowing in October 2001 was $3.5 billion.
In a paper on another Canadian intercompany financing litigation, I present the details for both of these issues. A 0.5% guarantee fee leads to the all-in cost of borrowing exceeding the interest rate on the corresponding government bond by more than 2% for the debt incurred in late 2001. While the CRA appears to be willing to accept an estimated credit rating of BBB, it is asserting that the 0.5% guarantee fee is above the arm's length standard. Credit spreads, however, vary over time and were elevated during this period.
This discussion has assumed that there is general agreement with respect to the appropriate credit rating being BBB. Much of the controversy with respect to arm's-length interest rates, however, centers on potential disagreements with respect to the appropriate credit rating.
The new OECD guidelines discuss the various aspects of this issue in paragraphs 10.62 to 10.87, which included matters such as whether an affiliate should be seen as being granted implicit support for its financial obligations by the parent and whether intercompany debt should be seen as subordinated debt in the absence of formal covenants.
The GE Capital Canada and Chevron Australia litigations witnessed several expert opinions on the appropriate credit rating for the borrowing affiliate where these considerations were hotly debated. In our scenario, the IRS might argue for a higher estimated credit rating while the German tax authorities might assert a lower credit rating. Even if the two tax authorities eventually agreed on the appropriate credit rating, this letter grade needs to be translated into a numerical credit spread.
Credit spreads depend on the estimated credit rating but also the macroeconomic environment at the time of the intercompany loan. This illustration of the issues involved assumed that the credit rating for the related party borrower was BBB. During tranquil periods such as the 1990s or the period from 2003 to 2007, credit spreads for BBB-rated corporate debt tended to be near 1.5%.
The period from 2001 to 2002, however, witnessed a rise in credit spreads which could be likened to a tidal wave. The period surrounding the Great Recession witnessed a spike in credit spreads that could be likened to a tsunami. As the coronavirus pandemic became more apparent, financial markets witnessed another spike in credit spreads.
Whether this will be only a tidal wave or another tsunami is not yet known. Given the heightened regulatory scrutiny of intercompany financing, multinationals with significant intercompany debt should carefully review whether their intercompany loan agreements are arm's length.
