|Revenue Recognition and Deferred Revenue [Abstract]|
Note 11 - Revenue Recognition
We recognize revenue when our customers obtain control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services, in accordance with implemented Topic 606 - an update to Topic 605. Revenue amounts presented in our condensed consolidated financial statements are recognized net of sales tax, value-added taxes, and other taxes.
In the normal course of business, we recognize revenue based on the customers' attendance of the course, mentoring training, coaching session or delivery of the software, data or course materials on-line. After a customer contract expires, we record breakage revenue less a reserve for cases where we allow a customer to attend after expiration. As of September 30, 2020, we have deferred revenue of $21.5 million related to contractual commitments with customers where the performance obligation will be satisfied over time, which ranges from six to eighteen months. The revenue associated with these performance obligations is recognized as the obligation is satisfied. As of September 30, 2020, we maintain a reserve for breakage of $2.2 million for the fulfillment of our obligation to students whose contracts expired during our COVID-19 60-day operational hiatus during Q2 (see Note 1 "General").
