BTC Yield is a KPI that represents the percentage change period-to-period of the ratio between Semler Scientific's bitcoin holdings and its Assumed Diluted Shares Outstanding. Assumed Diluted Shares Outstanding refers to the aggregate of Semler Scientific's actual shares of common stock outstanding as of the end of each period plus all additional shares that would result from the assumed exercise of all outstanding stock option awards. Assumed Diluted Shares Outstanding is not calculated using the treasury method and does not take into account any vesting conditions or the exercise price of any stock option awards.
