Basic EPS vs. diluted EPS
Diluted EPS numbers, unlike the "basic" EPS metric described above, account for all potential shares outstanding. Financial instruments like convertible debt and employee stock options, which are often used to raise capital and motivate employees, must be added to the outstanding share count to calculate a company's diluted EPS.
Let's calculate the diluted EPS for Netflix. The company has granted 6,592,000 stock options to employees, which raises the total outstanding share count to 451,290,000. Dividing the same $4,491,924,000 of net income into 451,290,000 equals an EPS value of $9.95.
