(d) Timangan Mining Berhad must choose its optimal capital structure. Currently, the firm has a 40 percent debt ratio and the firm expects to generate a dividend next year of RM4.89 per share and dividends are expected to grow at a constant rate of 5 percent for the foreseeable future. Stockholders currently require a 10.89 percent return on their investment. Timangan Mining Berhad is considering changing its capital structure if it would benefit shareholders. The firm estimates that if it increases the debt ratio to 50 percent, it will increase its expected dividend to RM5.24 per share. Because of the additional leverage, dividend growth is expected to increase to 6 percent and this growth will be sustained indefinitely. However, because of the added risk, the required return demanded by stockholders will increase to 11.34 percent. Required: Should Timangan Mining Berhad make the capital structure change? Advice the company by showing the value per share under the current capital structure and under the proposed capital structure. Explain the reason
