(1) The issuer's outside administrator for the issuer's Savings Excess Plan holds issuer stock in a pooled fund as a participant investment option. Participant contributions designated for investment in issuer common stock are accounted for as units of interest in the issuer stock fund. Each unit was valued at $61.6452 as of February 28, 2018. The unit value can fluctuate with fluctuations in the value of the issuer common stock and the daily cash position of the issuer stock fund. The number of shares of issuer stock attributable to the reporting person can be determined at any time by first multiplying the number of units in the reporting person's account by the then current unit price and dividing the total by the price of the issuer common stock. As of February 28, 2018, the reporting person held an equivalent of 94.3360 shares in the issuer Savings Excess Plan. The Savings Excess plan is a "Non-Qualified Plan" as defined in 16b-3(b)(2).

The unit value can fluctuate with fluctuations in the value of the issuer common stock and the daily cash position of the issuer stock fund. The number of shares of issuer stock attributable to the reporting person can be determined at any time by first multiplying the number of units in the reporting person's account by the then current unit price and dividing the total by the price of the issuer common stock.
