ONE 1 INTRODUCTION The term dividend refers to that part of profits of a company which is distributed by the company among its shareholders. It is the reward of the shareholders for investments made by them in the shares of the company. The investors are interested in earning the maximum return on their investments and to maximize their wealth. A company‚ on the other hand‚ needs to provide funds to finance its long-term growth. If a company pays out as dividend most of what it earns‚ then for

Uniform linear acceleration Introduction This topic is about particles which move in a straight line and accelerate uniformly. Problems can vary enormously‚ so you have to have your wits about you. Problems can be broken down into three main categories: Constant uniform acceleration Time-speed graphs Problems involving two particles Constant uniform acceleration Remember what the following variables represent: t = the time ; a = the acceleration ; u = the initial speed ; v = the final

INTRODUCTION Dividend policy is the decision for the firm to pay out earnings verses retaining and reinvesting them. Dividend decision has remained one of the tough challenges for financial economists. We are yet to understand completely the factors that influence dividend decision and the manner in which these factors interact. From the practitioner’s viewpoint dividend policy of a firm has an implication for investors‚ managers‚ lenders and other stakeholders. For investors‚ dividends whether
