First, I develop a comprehensive database of normal course issuer bids (NCIB) and report descriptive data on repurchasing activity between 1994 and 2005. I find that repurchase programs peak in 2000 and then decline. I also find evidence that repurchase programs are concentrated in certain industries. Next, using Compustat data, I investigate the characteristics of firms announcing repurchase programs. I find evidence that firms who announce repurchase programs are large in size and have high operating cash flows, low leverage, low share turnover and low dividend yields. I extend the repurchases literature by demonstrating that firms with low trading volume are more likely to initiate repurchase programs, consistent with an attempt to improve sell side liquidity. Finally, I investigate the market reaction to NCIB announcements. The results indicate that TSX firms experienced a significant market reaction to repurchase announcements between 1994 and 2005 as measured by both return and volume tests. I extend the repurchases literature by showing that announcement returns are higher for firms who followed through on their previous repurchase announcements. Little evidence exists of investor response to the disclosed reasons for repurchase programs.enrepurchasedisclosureDoctoral ThesisAccounting
