Cross-market information transfers of ADR firms: An investigation of emerging market economies

Level II and III ADRs permit issuers to be listed on the major U.S. exchanges with the stipulation that they comply with extensive SEC disclosure requirements. Foreign private issuers are compelled to file a set of audited financial statements prepared in accordance with U.S. GAAP, or alternatively, IFRS or Home Country Accounting Principles with attendant reconciliation to U.S. GAAP prior to 2008. Although the Form 20-F reconciliation is discontinued in 2008 for IFRS filers, non-U.S. issuers are required to satisfy other Form 20-F stipulations such as expanded Item 17 and Item 18 disclosures. We conjecture that non-U.S. firms choosing to be listed on the major U.S. exchanges will incur the added costs associated with the supplemental disclosure requirements in order to attract sufficient investor attention as to have the disclosures impounded in the home country equity share price in the manner described by Fishman et al. (1989). Because a prominent attribute of ADR firms is that they benefit from multiple-market trading, we investigate whether the Form 20-F disclosure cross-market information transfers are associated with emerging market economy status. We employ models of the cross-market ADR and equity security share returns and trading volume controlling for the emerging economy status and incremental firm-specific SEC Form 20-F accounting principles disclosures. Preliminary results indicate that (1) U.S. listed ADR firms from emerging economies experience greater cross-market information transfers associated with the SEC Form 20-F filing, and (2) that the increased cross-market information transfers associated with the SEC Form 20-F filing are proportional to the difference in quality of accounting principles employed for home country reporting purposes vis-à-vis the accounting principles employed for SEC Form 20-F reporting purposes. Results are consistent with a feedback process through which the new information disclosed by the SEC Form 20-F reporting requirements in the ADR market attenuates the price discovery process in the home country equity market when the difference in information environment quality is large.
