(1) | Net loss for the three and six months ended July 31, 2017 has been adjusted. See Note 2 for a summary of adjustments.
As the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in thousands):
| As of July 31,
| 2018 |  | 2017
| (unaudited)
Unvested restricted common stock issued and outstanding | 400 |  |  | 800 |
Stock options issued and outstanding | 20,898 |  |  | 33,360 |
Unvested RSUs issued and outstanding | 4,891 |  |  | 2,210 |
Unvested restricted stock awards issued and outstanding | 388 |  |  | 599 |
Shares related to convertible senior notes | 7,134 |  |  | — |
Shares committed under the ESPP | 360 |  |  | 1,082 |
Unvested shares subject to repurchase | 96 |  |  | 324 |
| 34,167 |  |  | 38,375 |
The Company expects to settle the principal amount of the 2023 Notes in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion option on diluted net income per share, if applicable. The conversion option will have a dilutive impact on net income per share of common stock when the average market price per share of the Company’s Class A common stock for a given period exceeds the conversion price of the 2023 Notes of $48.36 per share. During the three months ended July 31, 2018, the weighted average price per share of the Company’s Class A common stock exceeded the conversion price of the 2023 Notes; however, since the Company is in a net loss position there was no dilutive effect during any period presented.
