- Receive premium income now as payment against the possibility they will be required at some later date to deliver the asset in return for an exercise price less than the market value of the asset
- If call expires, profit = premium
- If call is exercised, profit = premium - (value of stock to deliver - exercise price paid for those shares)
- If that difference is larger than the initial premium, the writer incurs a loss
