Non-Regressive Tiered Plan (Per Execution)

The formula below will assess 0.0015 / share the first 500,000 shares traded in a month, 0.001 / share for shares 500,001 - 1,000,000 and 0.0006 / share for share 1,000,001 and up.

Regressive Tiered Plan (Per Execution)

The formula below will assess 0.0015 / share for the first 500,000 shares traded in a month. If the next tier is reached, the trader will receive a 0.0005 * 500,000 ($250) rebate and subsequent shares are assessed a rate of 0.001 / share. The rebate is credited on the execution that crosses the tier.
