Final answer:
Convertible bonds, stock options, and stock warrants, if dilutive, would cause the weighted average number of shares to increase when calculating diluted EPS.
Step-by-step explanation:
When calculating diluted EPS (Earnings Per Share), all of the following - convertible bonds, stock options, and stock warrants - if dilutive, would cause the weighted average number of shares to increase.
Convertible bonds are debt instruments that can be converted into a company's common stock at a predetermined price.
Stock options give employees or certain stakeholders the right to purchase company stock at a predetermined price. Stock warrants are similar to stock options and allow the holder to purchase shares at a specific price during a certain period.
