I got this announcement after logging onto IB sunday, it seems everything is done now. I checked to make sure i am not short any es futures contracts due to assignment, and i am not. So looks like everything is cash settled.

Thanks guys for your help on this. I am going to summarize the es mini sp500 options assignment process below for future reference or anyone who happens to see this thread later.
1) - For Mar, Jun, Sep, Dec expired options, it stops trading on the 3rd friday at 9:30AM EST
- For all other months, it stops trading on the 3rd friday at 4:15PM EST

2) The final price is determined by something called SOQ (special opening quotation). This number is published usually a few hours after the options stops trading. The symbol is SET, you can find it by going to below link and look for S&P 500 (SET)

You can read about the method used to determine the SOQ in this link(but honestly who cares):

3) If your options contract is ITM as per the SOQ and the option's strike, it will be cash settled, meaning you pay/gain the difference between the strike and SOQ.
4) You will be notified of the settlement from your broker. For example IB, notified me with the above announcement at midnight sunday.

Question, for a non quarterly options.
For example if i sold a feb itm call option, whose underlying is the march futures. Is assignment still cash settled, or will i actually get the march futures contracts in my account during the feb expiration.
