What is the impact of a stock split on the value of a corporation?

Hello, I will need three discussion responses typed to any of the three following questions that I will be posting below. Outside sources to the

responses would be great as well as further elaboration on them. Questions to choose from: Explain how the use of leverage can increase

shareholder’s wealth. Leverage can also impact you in your personal life. Explain how you can use it to your advantage. In theory, what happens to the shareholder’s worth before and after he/she receives a dividend from the company. What are the advantages of stock repurchases versus

paying dividends? What is the impact of a stock split on the value of a corporation? Why do companies do stock splits? What is the difference

between a stock dividend and a stock split? If a company is highly leveraged from an operating standpoint is it more likely or less likely to use financial leverage? Why or why not?
