a. Calculate the company's earnings per share and interpret.
b. Calculate the company's dividend payout ratio and interpret. 目
c. Calculate the company's dividend yield and interpret.

Answers

The company's earnings per share is 20, dividend payout ratio is 0.1  and dividend yield is 1.25.

What is Dividend payout?

The dividend payout is the ratio between dividend per equity share and earning per equity share.

Earning per share =  Earning net interest and tax/ Number of shares                 outstanding

                             = $6,000,000/3,00,000

                             = 20

Dividend per share = Total Dividend/ No of shares

                                 = $600,000/300,000

                                 = $2

Dividend payout ratio = Dividend per share/Earning Per Share

                                    = $2/20

                                    = 0.1

Market value per share = P/E Ratio × Earning per share

                                        = 8 × 20

                                         = $160

Dividend Yield =  Dividend per share/ Market Value Per Share

                         = $2/$160×100 = 1.25

Therefore the earning per share indicates the earnings of the company is attributable to the equity shareholders. The company's dividend payout ratio and dividend yield ratio indicate the percentage of earnings paid to shareholders via dividends.
