BUSINESS FINANCE Week 1 Introduction Finance is study of how individuals, business and institutions acquire, spend, and manage financial resources. The main goal of managers is to maximise the market value of the firm, which maximise the wealth of shareholders. Managers however, do not always maximise the firm value. Reasons: - Managers may intend to maximise the value of the firm in the long-term in expense of the lower value in the short-term. - Agency Issues, where there is a conflict between the managers and the shareholders. 3

Fn is the accumulated value at time n of amount of cash P0, with rate of return required by Investors r.
