Accounting standards and earnings quality-evidence from registered ADRs

This paper examines the changes in earnings quality of registered American Depositary Receipts (ADRs) as a result of switching accounting standards. We aim to shed light on the potential impact of International Financial Reporting Standard (IFRS) adoption on US firms. A suboptimal approach to achieve this goal is through examination of US firms' surrogates such as ADRs. Unlike previous studies, we made a distinction between registered and unregistered ADRs and affirmed that registered ADRs are the closest surrogates with which to conduct our analysis because they are exclusively required to adhere to the Securities and Exchange Commission (SEC)'s stringent disclosure requirements. When cross-listing their equity on the US exchanges, foreign issuers can file their financial reports with the SEC using IFRS, US GAAP (generally accepted accounting principles), or their domestic GAAP with reconciliation to US GAAP. An improvement in earnings quality is documented when ADRs adopt US GAAP or IFRS versus domestic GAAP. However, when the comparison is made between US GAAP and IFRS, no difference in earnings quality is documented. These results indicate that switching to high-quality accounting standards is likely to improve earnings quality. This improvement is maximized when the difference between reporting standards is high and minimized if otherwise. Our conclusion is that the adoption of IFRS in the US is unlikely to change earnings quality of local issuers. Moreover, we drew a distinction between reconciliation with and adoption of high-quality accountings standards and find that while the former can enhance earnings quality, the latter can further improve it.
