Early Assignment of Covered Calls Position in Lowe's Companies Inc.

I have now returned from vacation and am now catching up on my emails.  Last Tuesday morning, I was notified by Schwab that my Covered Calls position in Lowe's Companies Inc. was assigned early (on the day prior to their ex-dividend date).  The owners of the Call options elected to purchase the 200 shares at the $170.00 strike price and thus also capture Lowe's $1.05 per share ex-dividend.  So, I captured all the original $1.48 per share [$11.92 Call options premium - ($180.44 stock purchase price - $170.00 strike price)] time value as profit.   

As detailed below, the early assignment of this Lowe's Covered Calls position resulted in a return-on-investment of: +0.9% absolute return-on-investment (equivalent to +45.6% annualized-return-on-investment) for the 7 days this position was held.  This result exceeded the maximum potential annualized roi of +30.4% if the stock would instead be assigned on its July 29th, 2022 options expiration date.  The reason early assignment is preferred is that the Covered Calls Advisor's Dividend Capture Strategy spreadsheet was designed to identify positions where the annualized return-on-investment (aroi) from early assignment is greater than what might be achieved if the stock was instead assigned later on its options expiration date.

The transactions and detailed results for this Lowe's Covered Calls position were as follows:
