 Cost Basis Calculator

Calculating the cost basis of your stock can be a very difficult and time-consuming process.  In order to provide a resource to our shareholders, Anadarko would like to make you aware of the NetBasis Cost Basis system, a fee-based service, provided by a third party, which you may find useful for calculating the cost basis of your stock.

For a fee, you can use NetBasis, NetWorth Services’ internet-based cost basis calculation system, to calculate the cost basis for your Anadarko stock.  To use the system, you will need your purchase/acquisition and sale dates, and the number of shares or dollar amount acquired on those dates.  NetBasis will do the rest, automatically adjusting for any corporate actions or dividend reinvestments.  For your convenience, a hyperlink to the Netbasis Cost Basis System is provided below.

If you have any questions or problems 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.

If you select the NetBasis icon above, you will leave Anadarko’s website and will be redirected to the NetBasis website.  NetBasis is not affiliated with Anadarko, or its subsidiaries, and the content on the NetBasis website is not under Anadarko’s control.  Anadarko is providing a link to NetBasis as a convenience, for your information only.  Anadarko shall have no liability for any information received from the NetBasis Web site.
