Intangible Assets Are Not Hard-to-Value

Posted by Ednaldo Silva

We can determine the value of any asset, including intangible assets, from knowledge about its initial investment, comparable rate of return, and estimated life of the identifiable asset. For this purpose, CAPM (capital asset pricing model) is inapplicable to determine a comparable rate of return for intangible assets because CAPM is designed to estimate rates of return of traded equity shares, which reflect a stream of prospective dividends plus share price variation (capital gains or loss), and not a stream of operating profits. For a selected enterprise, the streams of income (operating profits versus dividends and capital gains) and measures of risks are not the same for the return of intangible assets compared to that of equity shares.

Transfer Pricing Memoir

Posted by Ednaldo Silva

When we started (1988) in transfer pricing from academia, the IRS dominant paradigm was forcing single point estimates of gross profits indicators in audit, including gross profit margin for controlled inbound distributors, and gross profit markup for controlled outbound manufacturers and service providers. The Berry ratio (gross profits/XSGA), which was introduced by Charles Berry in Du Pont, was an unspecified “fourth” method. See United States Court of Claims. E. I. Du Pont de Nemours and Company v. The United States, Nos. 256-66 & 371-66, April 18, 1978. (Cite as: 1978 WL 3449 (Ct. Cl. Trial Div.)). When we started, IRS transfer pricing economics was not bachelor's degree level, and we suspect that it has not advanced.

Location Savings Adjustment to Net Profits

Posted by Ednaldo Silva

The OECD, UN, and United States transfer pricing rules recognize that tax administrations and controlled MNE (multinational enterprise) groups must consider location savings adjustments when uncontrolled comparable enterprises operate in different geographical markets from the tested party. Location savings adjustments are needed when we can measure (in different geographic markets; e.g., UK versus Nigeria or South Africa or US versus Brazil or Mexico) significant differences in wage shares and adopted technology measured by incremental capital/output ratios.

Profit Margin by Indirect Least Squares

Posted by Ednaldo Silva

A practice in transfer pricing is to select a “net profit indicator” (such as operating profit margin or return on assets) and calculate quartiles among i = 1, 2, …, N selected enterprise-level comparables. This practice produces unreliable profit indicators that can’t survive audit scrutiny. A major fallacy of this practice is to estimate structural equations when reduced-forms should be estimated. In this blog, we discuss and solve this fallacy.

Selection of the appropriate “net” profit indicator (NPI)

We discuss three contending transfer pricing models. Let P = “Net” profits, S = Sales, and A = Assets: For simplicity, we don’t consider profit markup on total costs, and exclude random errors:

Coefficient of Variation of Return on Assets

Posted by Ednaldo Silva

In DuPont’s profit identity, “return on assets” (profit rate) is equal to profit margin multiplied by asset turnover. Using DuPont’s profit formula, combined with an assumption that profit margin and asset turnover (measures of economic performance and adopted technology) are independent, we showed on a prior blog that the coefficient of variation of return on assets is greater than of the profit margin. It follows that profit margin is more reliable (has a lower coefficient of variation) than return on assets. In science, coefficient of variation is an accepted method of determining the reliability of a selected variable.

Most Reliable Profit Indicator Based on Coefficient of Variation

Posted by Ednaldo Silva

Transfer pricing tax compliance is devoid of external CUP (comparable uncontrolled prices). Therefore, we must select (under the TNMM and under the Profit Split Method) the most appropriate “net” profit indicator (NPI) from comparable uncontrolled enterprises. Most appropriate is the most reliable among competing profit indicators. In economics and statistics, reliability is measured by the coefficient of variation (standard deviation / mean) of the selected variable.

Using a distributed lag model to determine arm’s length profits in transfer pricing

Posted by Ednaldo Silva

Most empirical research in transfer pricing lack valid economic principles, relying instead on ad hoc specification. This faulty practice is somewhat permitted by misconceived transfer pricing regulations based on the OECD model.

US and OECD method for computing arm’s length profit margin is flawed

Posted by Ednaldo Silva

We analyzed the statistical relation between operating profits and net sales for a large group of US listed companies using RoyaltyStat®’s online database of company financials. The results of this study have led us to conclude that the OECD and US transfer pricing guidance on the comparable profits method (TNMM) does not produce the most reliable measure of an arm’s length operating profit margin and that other more informed measures should be considered. Instead of simple regulatory prescription, we apply economics and statistics to reach these conclusions.

OECD Inventory Adjustment to Profits is Spurious

Posted by Ednaldo Silva

In transfer pricing, a frequent “comparability adjustment” to (gross or operating) profits involving inventories is spurious. The OECD is wrong disseminating misconceived guidance about “working capital” adjustment that includes inventories. The inventory adjustment to profits is bogus because inventory is included in cost of goods sold (COGS); thus, the same inventory variable appears on both sides of the adjustment equation, making the proposed adjustment false. Follow at your peril: OECD, Comparability Adjustments (July 2010), ¶¶ 16-17:
