Definition: In finance, a "devolvement" is a financial transaction that involves the exchange of one asset for another. This can be in the form of an asset's purchase or sale, such as a stock purchase or a bond issuance. For example, let's say you have two assets: a share of a popular technology company and a mortgage on your home. If you sell the share for $100 per share and then buy back the same amount at a discount price of $50
