WMB Cost Basis Information

A:

Calculating cost basis information during tax preparation time can be a difficult and time-consuming process. If you are a Williams shareholder and you need a cost-basis calculation, we encourage you to contact your broker if you hold your Williams shares in streetname or Computershare (800.884.4225) if you hold your shares incertificate or book-entry form.

Williams also provides a link to the NetBasis system via a hyperlink below. For a fee, NetBasis will automatically calculate the cost basis for your Williams stock, adjusted 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.

If you have any questions about using NetBasis, you can call their 24/7 customer care call center (1.888.802.2747) or use the Live Web Chat service located on the Help button once you have logged on to the system.

By selecting the NetBasis link below, you will leave the Williams website and will be redirected to the NetBasis system.
