Multiple year data will also be useful in providing information about the relevant business and product life cycles of the comparables. Differences in business or product life cycles may have a material effect on transfer pricing conditions that needs to be assessed in determining comparability. The data from earlier years may show whether the independent enterprise engaged in a comparable transaction was affected by comparable economic conditions in a comparable manner, or whether different conditions in an earlier year materially affected its price or profit so that it should not be used as a comparable ...

In order to obtain a complete understanding of the facts and circumstances surrounding the controlled transaction, it generally might be useful to examine data from both the year under examination and prior years. The analysis of such information might disclose facts that may have influenced (or should have influenced) the determination of the transfer price. For example, the use of data from past years will show whether a taxpayer’s reported loss on a transaction is part of a history of losses on similar transactions, the result of particular economic conditions in a prior year that increased costs in the subsequent year, or a reflection of the fact that a product is at the end of its life cycle. Such an analysis may be particularly useful where a transactional profit method is applied. See paragraph 1.151 on the usefulness of multiple year data in examining loss situations. Multiple year data can also improve the understanding of long term arrangements ...

Data from years following the year of the transaction may also be relevant to the analysis of transfer prices, but care must be taken to avoid the use of hindsight. For example, data from later years may be useful in comparing product life cycles of controlled and uncontrolled transactions for the purpose of determining whether the uncontrolled transaction is an appropriate comparable to use in applying a particular method. The conduct of the parties in years following the transaction will also be relevant in accurately delineating the actual transaction ...
