Context

• A "disposition to the issuer" under Rule 16b-3(e) is an exempt transaction for purposes of short-swing profit rules when certain conditions are met. Such dispositions often reflect routine actions (for example, share surrender or issuer repurchase arrangements) and do not by themselves indicate the insider’s view on company prospects.
