1 The risk-free interest rate is based on the yield of a U.S. treasury bond with a similar maturity as the expected life of the awards. 2 The expected life in years for awards granted was based on the historical exercise patterns experienced by the Company when the award is made. 3 The determination of expected stock price volatility for awards granted in each of the three years ended December 31, 2017, 2016 and 2015 was based on historical Superior common stock prices over a period commensurate with the expected life. 4 The dividend yield assumption is based on the history and expectation of the Company’s dividend payouts. Restricted Stock The Company has granted restricted stock to directors and certain employees under the terms of the 2013 Plan which vest at a specified future date, generally after three years, or when certain conditions are met. The shares are subject to accelerated vesting under certain circumstances pursuant to the 2013 Plan. Expense for each of these grants is based on the fair value at the date of the grant and is being recognized on a straight-line basis over the respective service period. As of December 31, 2017, the Company had $0.7 million of unrecognized compensation cost related to nonvested grants expected to be recognized over the weighted average service period of 2.01 years.

Performance Shares In 2016, the Compensation Committee of the Board of Directors approved grants of performance shares under the terms of the 2013 Plan. Under the terms of the grants, certain employees received service-based or service-based and performance-based shares. The service-based awards vest after the service period is met, which is generally three to five years. Expense for these grants is based on the fair value on the date of the grant and is being recognized on a straight-line basis over the respective service period. The performance-based shares generally vest after five years if the performance and service targets are met. The Company evaluates the performance conditions associated with these grants each reporting period to determine the expected number of shares to be issued. Based upon this evaluation, expected expenses for these grants are being recognized based on the fair value on the date of the grant on a straight-line basis over the respective service period. The shares are subject to accelerated vesting under certain circumstances as outlined in the 2013 Plan. As of December 31, 2017, the Company had $1.6 million of unrecognized compensation cost related to nonvested grants expected to be recognized over the weighted average service period of 3.25 years.
