Lost Stock Certificate

If a stock certificate is lost, stolen or destroyed, notify the transfer agent in writing so that a "stop transfer" can be placed on the missing certificate. The transfer agent will send you the necessary forms and instructions for obtaining a replacement certificate. You may be required to obtain and pay for the cost of an indemnity bond. If you find the missing certificate, notify the transfer agent in writing immediately so that the stop transfer can be removed. To avoid loss, theft or destruction, we recommend that you keep your certificates in a safe place, such as a safe deposit box at your bank.

Taxpayer Identification Number

Federal Law requires that each stockholder provide a certified Taxpayer Identification Number (TIN) for his/her stockholder account. For individual stockholders, your TIN is your Social Security Number. If you do not provide a certified TIN, the transfer agent may be required to withhold 28 percent from your dividends for federal income taxes.

Address Change

It is important to notify the transfer agent immediately, by phone, in writing or by FAX, when you change your address. If your account address is not updated, your dividend check and other important mail may get delivered to the wrong persons. Additionally, if the Post Office returns your mail as undeliverable, your assets will eventually be considered abandoned and claimed by the state of your last known residence. Seasonal addresses can also be entered for your account.

Cost Basis Calculator

During tax time, shareholders are burdened with trying to determine their cost basis in order to report their capital gains to the IRS. This can be a very difficult and time-consuming process even for professional tax preparers. So in order to provide a resource to our shareholders, Ƶ is pleased to announce the availability of the NetBasis Cost Basis system.

NetBasis will automatically calculate the cost basis for your Ƶ stock, by adjusting for any corporate actions or dividend reinvestments. All you need to use NetBasis are your purchase/acquisition and sale dates, number of shares or dollar amount acquired and that's it! NetBasis will do the rest.

If you have any questions about using NetBasis, you can call their 24/7 Customer Care Call Center, 1-888-80-BASIS (1-888-802-2747) or use the Live Web Chat service located on the Help button once you have logged on to the system.
