Geographic earnings disclosure and trading volume

Beginning with Statement of Financial Accounting Standards No. 131 (SFAS 131), Disclosures about Segments of an Enterprise and Related Information, most US multinational firms no longer disclose geographic earnings in their annual reports. Given the recent growth in foreign operations of US firms and the varying operating environments around the world, information (or lack thereof) related to geographical performance can affect investors' information set. Using empirical tests that closely follow the [Kim, O., Verrecchia, R., 1997. Pre-announcement and event-period private information. journal of Accounting and Economics 24, 395-419] model, we find results consistent with their predictions. Specifically, using a sample of firms with Substantial foreign operations. we find evidence of a decrease in event period private information following adoption of SFAS 131 for firms that no longer disclose geographic earnings, These results suggest that decreased public information (i.e.. non-disclosure of geographic earnings) reduces the ability of investors to utilize or generate private information in conjunction with the public announcement of quarterly earnings, which dampens trading. We also find evidence of a decrease in pre-announcement private information following adoption of SFAS 131. This is consistent with an overall improvement in public disclosures that has the effect of reducing differences in the precision of private information across investors in the period prior to the earnings announcement. However, such an effect is observed for both firms which no longer disclose geographic earnings and for firms that continue to disclose geographic earnings. (C) 2009 Elsevier Inc. All rights reserved.
