The impact of mandatory IFRS adoption on foreign mutual fund ownership: The role of comparability

► Foreign mutual fund ownership increases in the EU after mandatory adoption of IFRS. ► The increase in mutual fund ownership is larger when IFRS adoption improves comparability. ► Both implementation credibility and increased uniformity are important factors leading to improved comparability. ► The effects of improved comparability do not increase domestic mutual fund ownership. ► The effects of improved comparability on foreign fund ownership are primarily driven by foreign global funds, as opposed to foreign regional, country, and other funds.
