As of September 30, 2020, estimated revenue expected to be recognized in the future totaled $72.8 million, including certain held-for-sale orders of $5.2 million, primarily related to customer order backlog, which includes firm orders for future shipment to our Retail customers, as well as unfulfilled consumer orders within the Direct channel. Direct orders of $23.0 million and Retail orders of $49.8 million, including certain held-for-sale orders of $5.2 million comprised our backlog as of September 30, 2020, compared to Direct orders of $20.6 million and Retail orders of $13.6 million as of June 30, 2020. The estimated future revenues are net of contractual rebates and consideration payable for applicable Retail customers, and net of current promotional programs and sales discounts for our Direct customers.
