The wealth effects of accelerated stock repurchases

Abstract

Purpose

The wealth effect of accelerated stock repurchase (ASR) documented by previous studies is not as large as the authors would have expected. The authors believe that there are potentially important sampling problems in the previous studies, which make the results less reliable. Identifying a number of factors that can possibly affect the announcement-period returns, the purpose of this paper is to reexamine the wealth effect of ASRs.

Design/methodology/approach

The paper identifies a number of factors that can possibly affect the announcement-period returns to ASRs which include: whether an ASR announcement in the press is the initiation date or the completion date of the ASR; the size of the ASR program; whether an ASR is part of an open market repurchase (OMR) program; the frequency of ASR announcements by a firm; whether other corporate news is announced simultaneously with an ASR. The paper partitions the ASR sample into three groups, and then examines the wealth effect of these groups.

Findings

The empirical results show that the market reacts differently to the announcement of ASR in these three groups. The three-day announcement-period CAR (t=−1, +1) is 3.59 percent for the high-wealth-effect group, 2.01 percent for the medium-wealth-effect group, and 1.48 percent for the low-wealth-effect group. The paper also identifies the size of the ASR program, whether the ASR is announced simultaneously with an OMR or not, and the frequency of ASR announcements are the most important determinants of the announcement-period abnormal returns.

Originality/value

These findings suggest that the weaker wealth effects of ASRs that have been documented in previous studies are due to sampling related issues.
