Date listed is the first day this option was exercisable and the option expiration is 9/26/2017 ( 2 )The accounts track common shares on a one-for-one basis ( 3 )Prior to 10-1-14 the account balance related to the theoretical common share investment option could be immediately transferred to other investment options under the terms of the deferred compensation plan. ( 4 )The Company amended its Amended and Restated 2005 Deferred Compensation Pan for Outside Directors (the "Plan") effective October 1, 2014. The amendment includes a provision that effective October 1, 2014 and thereafter, any amount credited in a participant's account to the phantom stock fund (i.e. theoretical Company common shares deemed investment option) may not be transferred to an alternative deemed investment option under the Plan until distribution from the Plan. Distributions are made only in common shares of the Company and generally commence upon leaving the Company. ( 5 )The amount shown reflects an additional 68 theoretical common shares (i.e. phantom stock) pursuant to the dividend reinvestment feature of Worthington Industries, Inc.'s Deferred Compensation Plan for Directors.
