Each month, your previous month's signature spend is totaled and invested. You can learn more about what a signature spend is here. The investment is done on the 2nd Wednesday following the previous month's spend. If that Wednesday is not a business day, the investment will be done on the following business day. That month's investment program term will end in one calendar year and one day, then will automatically be deposited into your debit account.
Example: You spend $400 using signature transactions from January 1, 2021 to January 31, 2021. The second Wednesday following January 31 is February 10th. It takes 3 business days for the purchase to settle in your investment account. On February 16th, you should see your match processed and invested in your match account.
