Apple has stopped disclosing how much it spends on advertising, as revealed in its annual report (10-K) filed with the United States Securities and Exchange (SEC) commission in October.
Apple's motives behind this move are unclear and the SEC filing makes no mention of its advertising expenses for the whole 2016. In 2015, Apple's ad spend rose fifty percent to a record $1.8 billion.
The decision to stop reporting how much it spends on advertising may have something to do with the fact that the iPhone maker ended 2016 with its lowest operating margin since 2009, partially due to spending more ad dollars to drive total revenue.
