Cost Basis Calculator

As a helpful service to our shareholders, ALLETE, Inc. has partnered with NetWorth Services to provide a hyperlink to NetBasis, NetWorth's Internet-based cost basis calculation system.

For a fee, you may use NetBasis to calculate the cost basis for your ALLETE common stock, adjusted for any corporate actions or dividend reinvestments. All you need to use NetBasis are your purchase/acquisition/sales dates and the number of shares acquired and/or sold on those dates.

If you have any questions about using NetBasis, you can call their 24/7 Customer Care Call Center at 1-888-80-BASIS (1-880-802-2747) or use the Live Web Chat service located on the Help button once you have logged on to the system.
