Below is a copy of an email I received from Scottrade from EP. Something is up, and I am not sure what.
Re. stock symbol / cusip - EP / 28336L109:
The above-listed stock is part of a non-mandatory reorganization or tender offer, which currently expires on 05/23/2012.
Where to find more information: For offers initiated by the company, information can often be found on the company's Web site. If the offer was initiated by a third party, additional information can be obtained by contacting your local branch office. For mini-tender offers, the US Securities and Exchange Commission has urged caution. To review an SEC educational piece entitled "Mini-Tender Offers: Tips for Investors," please go to http://www.sec.gov/investor/pubs/minitend.htm If you decide to participate in this offer, you will need to inform your local Scottrade branch office no later than 10 a.m. ET on the expiration date listed above, and a $25 fee will be charged to your account. These shares must then remain in your account until the reorg/tender takes place. Please note that the expiration date for such actions is often extended and terms of the offer are subject to change.
