In terms of Securities law, financial contract is an arrangement that takes the form of an individually negotiated contract, agreement, or option to buy, sell, lend, swap, or repurchase, or other similar individually negotiated transaction commonly entered into by participants in the financial markets. A financial contract involves securities, commodities, currencies, interest or other rates, or any other financial or economic interest similar in function. (USLegal)

When a company issues shares of common stock for the public to buy and later decides to buy some of those shares back, that's considered a repurchase rather than a redemption. The major difference between the two is that the shares bought back in a redemption are considered a fixed-income security that is expected to be bought back by the issuer. A repurchase of shares, however, reduces the number of outstanding shares that a company has, and can increase the company's holdings so that it remains or regains majority shareholder status.
