Stockholders agreements   As authorized by our Company’s Board of Directors (the Board), on January 27, 2014, the Company entered into an Amended and Restated Rights Agreement (Amended Rights Agreement) with Computershare Inc., as Rights Agent (Rights Agent), amending, restating and replacing the Rights Agreement, dated as of August 22, 2013 (Original Rights Agreement), between the Company and the Rights Agent. Pursuant to the terms of the Original Rights Agreement, one preferred stock purchase right (a Right) was attached to each outstanding share of Common Stock of $0.50 par value of the Company (Common Stock) held by holders of record as of the close of business on September 3, 2013. The Company has issued one Right in respect of each new share of Common Stock issued since the record date. The Rights, registered on August 23, 2013, trade with and are inseparable from our Common Stock and will not be evidenced by separate certificates unless they become exercisable. The purpose of the Amended Rights Agreement is to diminish the risk that the Company's ability to use its net operating losses and other tax assets to reduce potential future federal income tax obligations would become subject to limitations by reason of the Company's experiencing an "ownership change" as defined under Section 382 of the Internal Revenue Code. Ownership changes under Section 382 generally relate to the cumulative change in ownership among stockholders with an ownership interest of 5% or more (as determined under Section 382's rules) over a rolling three year period. The Amended Rights Agreement is intended to reduce the likelihood of an ownership change under Section 382 by deterring any person or group from acquiring beneficial ownership of 4.9% or more of the outstanding Common Stock. The amendments to the Original Rights Agreement also extended the expiration date of the Rights from August 20, 2014 to January 26, 2017 and amended certain other provisions, including the definition of "beneficial ownership" to include terms appropriate for the purpose of preserving tax benefits. We are submitting the Amended Rights Agreement for stockholder approval at our 2014 annual meeting and the Rights will immediately expire if stockholder approval is not received. Each Right entitles its holder to purchase from the Company 1/1000th of a share of a newly authorized series of participating preferred stock at an exercise price of $55.00, subject to adjustment in accordance with the terms of the Amended Rights Agreement, once the Rights become exercisable. In general terms, under the Amended Rights Agreement, the Rights become exercisable if any person or group acquires 4.9% or more of the Common Stock or, in the case of any person or group that owned 4.9% or more of the Common Stock as of January 27, 2014, upon the acquisition of any additional shares by such person or group. In addition, the Company, its subsidiaries, employee benefit plans of the Company or any of its subsidiaries, and any entity holding Common Stock for or pursuant to the terms of any such plan, are excepted. Upon exercise of the Right in accordance with the Amended Rights Agreement, the holder would be able to purchase a number of shares of Common Stock from the Company having an aggregate market value (as defined in the Amended Rights Agreement) equal to twice the then-current exercise price for an amount in cash equal to the then-current exercise price. The Rights will not prevent an ownership change from occurring under Section 382 of the Code or a takeover of the Company, but may cause substantial dilution to a person that acquires 4.9% or more of our Common Stock.
