The expected term for options was based on the results of a Monte Carlo simulation model, using the model’s estimated fair value as an input to the Black-Scholes-Merton model, and then solving for the expected term. The risk-free interest rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of the grant. The expected volatility was derived using a term structure based on historical volatility and the volatility implied by exchange-traded options on our stock. The dividend yield was calculated based on our annual dividend as of the option grant date.

In establishing the discount rate, we reviewed published market indices of high-quality debt securities, adjusted as appropriate for duration, and high-quality bond yield curves applicable to the expected benefit payments of the Delaware Plan. To develop the expected long-term rate of return on assets assumption, we considered the historical returns and future expectations of returns for each asset class, as well as the target asset allocation of the Delaware Plan portfolio. Prior to the termination and settlement of the Delaware Plan the fundamental goal underlying the investment policy was to ensure that its assets were invested in a prudent manner to meet its obligations as such obligations became due. The primary investment objectives included providing a total return that would promote the goal of benefit security by attaining an appropriate ratio of plan assets to plan obligations, diversifying investments across and within asset classes, minimizing the impact of losses in single investments and adhering to investment practices that complied with applicable laws and regulations. The investment strategy for equities emphasized U.S. large cap equities with the portfolio’s performance measured against the S&P 500 1 The Delaware Plan had a long-term target asset mix of 60% 40% October 3, 2015 Percentage of Plan Assets at Measurement Date Large-cap equities 37.6 % Mid-cap equities 7.7 % Small-cap equities 8.2 % International equities 8.8 % Fixed income securities 37.3 % Cash and cash equivalents 0.4 % Supplemental employee retirement plan.
