“…See, e.g., Maxwell and Rao (2003) for spin-offs, Maxwell and Rao (2003) for share repurchases, Penas and Unal (2004) for bank mergers, and Ambrose et al (2012) for fallen angels. Several studies employ 2-or 3-month event windows for mergers and acquisitions (Billett et al (2004)), for leveraged buyouts (Baran and King (2010)), and for mergers (Bodnaruk and Rossi (2016)). Thus, in addition to the return on the filing month, we further calculate bond returns over two additional event windows: (−1, 0) and (−1, 1).…”
