The line you quoted is from a summary of accounting policies rather than a note to anything specific in the financial statements.
Consider the case where nwbo treats a patient via Specials, Compassionate Use, right-to-try, etc. It's going to show up on the Income Statement rather than Balance Sheet. There may or may not be Revenues, depending on the situation. There definitely would be Expenses in every case.
Recent 10-K filings have mentioned compassionate use, but with the text "as previously reported" rather than anything new.
Up to and including the April 2019 10-K, there was a note about Susan Goldman (Les' wife) being paid $120K per year related to compassionate use:
* Susan Goldman is the wife of Leslie J. Goldman. She is a former nurse with a Masters Degree in Medical Surgical Nursing who serves as Director of Patient Affairs, handling compassionate use cases. Mrs. Goldman was paid $120,000 for the years ended December 31, 2018 and December 31, 2017 for services performed during such periods.
Susan Goldman is not mentioned in 2020 or 2021 filings. Note that the salary table for 2020 and 2021 is in the proxy and the 10-K refers to the proxy.
