One year ago, the Chinese e-commerce company Alibaba Group floated its shares in the biggest Initial Public Offering in US history. Alibaba Group priced its shares at $68 raising $21.8 bn and valuing the company at $167.6 bn. The IPO prospectus notes that Alibaba does not plan to pay dividend in the foreseeable future and reported annual earnings of $3.52 per share.

Currently, the Return on Equity is 25% but it is expected to decrease to 12.5% after year 3. Investors agree that the appropriate discount rate is 10% and that in 4 years the firm will start distributing a dividend and will keep the payout ratio constant forever.

After one year of trading, Alibabas share price closes at $50.73. This trading price is the consensus valuation among investors and analysts.

b. What is the implied PVGO (Present Value of Growth Opportunities)?
