Eliminating the 20-F reconciliation from IFRS to U.S. GAAP: Short-term and long-term liquidity effects

This paper examines the effects of the SEC’s 2008 decision to no longer require foreign private issuers using IFRS and trading on U.S. exchanges to reconcile their financial statements to U.S. GAAP. Extant research has found conflicting results using short event windows, while studies using longer event windows have found limited capital market impact from eliminating the reconciliation. Motivated by the SEC’s interest in understanding how disclosure rules impact market liquidity, we examine changes in effective bid-ask spreads, the price impact of trades, and quoted depth around 20-F filing dates for a sample of foreign private issuers. We find that effective spreads increase more around 20-F filing dates for filers using IFRS than for filers using U.S. GAAP, suggesting the 20-F report is more informative for filers using IFRS. We then find, in a subsample of filers using IFRS, that the increase in effective spreads for IFRS firms around 20-F filing dates is directly related to the magnitude of differences in book values between IFRS and U.S. GAAP. In sum, our results suggest a loss of useful information after the SEC’s rule change.
