Can we get both refund and sales data from Summary Sales Report?

I'm wondering how the data in Summary Sales report is aggregated. Does Apple aggregate refunds and sales together?

Say, if a specific product have 2 sales and 1 refunds, and the price is $5. Will the corresponding report have 1 row saying 1 sale for $5 or have 2 rows saying 2 sales for $5 each and 1 refund for -$5?

According to my insight into the Summary Sales Report, Apple indeed separate the refunds from sales. So in the example., the corresponding report will have 2 rows saying 2 sales for $5 each and 1 refund for -$5.
