The effect of the 2018 Notes and the 2020 Notes was excluded from the diluted net income/loss per share since they may be settled in cash or shares at the Company’s option, and the Company’s current intention is to settle up to the principal amount of the converted notes in cash and any excess conversion value (conversion spread) in shares of the Company’s common stock. As a result, the 2018 Notes and the 2020 Notes have no effect on diluted net income/loss per share until the Company’s stock price at period end exceeds the conversion price of $94.15 per share for the Notes.
