ITM options not assigned at expiration
I was short three ROKU Feb 28 $115 put contracts coming into last week. ROKU closed on Friday at $113.67. I fully expected to be put 300 shares of ROKU at the end of AH trading last Friday. I was only assigned 100 shares and the other two contracts expired.
Has anyone ever seen an option that far in the money go unassigned? This trade was made through Interactive Brokers. I keep checking my IB account this weekend thinking I'm going to find the entire 300 shares of ROKU in my account but it hasn't happened...yet.
Any thoughts?
Final Resolution: the two ITM contracts went unassigned. Strange!

Could have got lucky and whoever owned the options didn't have cash to cover the position, or if it's someone who owns the stock and bought it as insurance, they might not want to sell their shares for barely $150 in profit if they bought in way higher or expect the stock to rise along with netflix with all the people staying home.
Why would the put owners need cash to cover the position? By owning the put, they had the right to put the stock to me at $115, while it was trading substantially lower throughout all of Friday. That doesn't require any cash on their part. ROKU actually traded in the $107s on Friday. It's just very odd to see anyone leave money on the able.
If they bought the put but didn't own the stock, they have 3 options at expiry. Buy the shares at market price and then sell them to you for profit, sell the put for profit, or let it expire. They might not have had enough money to do the first option, is what I was saying.
They also might just be someone that didn't manage their positions. Some brokers would auto exercise or try to sell the option, maybe he relied on the broker to do it for him but the broker couldn't find a buyer so it expired.
I had my auto excercise turned off by my broker after it happening once. I have fallen asleep through expiry a few times also.
