This paper provides an update on BEA’s research into ultimate host economy statistics for U.S. direct investment abroad (USDIA). A previous BEA working paper (Brew et al. 2023) explored producing statistics on equity position by ultimate host economy using six different methods for reallocating equity position by immediate host economy. The present paper introduces three sets of methodological updates to the previous research: (1) modifications to three of the original six reallocation methods, (2) the addition of three new methods to the collection of methods under consideration by BEA, and (3) the incorporation of U.S. affiliates into the ownership chains used to reallocate USDIA equity position. Of the nine methods under consideration, six are selected for comparison across a variety of dimensions using USDIA data collected for 2019 and 2020. Based on this comparison, three methods are identified as meriting further exploration, and country and sector-level results for 2019 and 2020 are presented for the selected methods.
