Stock Option Fair Value
The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2021 grants:
Volatility26.30 %
Risk-free interest rate0.86 %
Dividend yield1.10 %
Expected term (in years)5.7
Weighted-average fair value / share$23.20 
Expected volatility is calculated based on an analysis of historic volatility measures for Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.
Restricted Stock Unit Grants
The following is a summary of restricted stock unit activity for the six months ended June 30, 2021. The fair value of the restricted share unit awards is determined using the closing price of our common stock on date of grant:

Outstanding at June 30, 2021177 $102.86 
(a) Represents an increase in the number of original TSR performance share units awarded based on the final market condition achievement at the end of the performance period of such awards.
The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2021 grants:
Volatility33.5 %
Risk-free interest rate0.24 %
