Each retailer reports their sales activities at different intervals (monthly vs quarterly, etc). Therefore, in any given month you could see sales reported that actually occurred months prior. As we receive this information, we use all commercially reasonable efforts to provide it to you as soon as possible.
Most payments are received once per month and provide information from the month that ended roughly 60-90 days prior. For example, if you receive sales in the month of January, they will be reported in the month of April.
