> We anticipate that our Daily Active Users growth rate will decline over time if the size of our active user base increases or we achieve higher market penetration rates. If our Daily Active Users growth rate slows, our financial performance will increasingly depend on our ability to elevate user engagement or increase our monetization of users.
> In addition, because our products typically require high bandwidth data capabilities, the majority of our users live in countries with high-end mobile device penetration and high bandwidth capacity cellular networks with large coverage areas. We therefore do not expect to experience rapid user growth or engagement in countries with low smartphone penetration even if such countries have well-established and high bandwidth capacity cellular networks. We may also not experience rapid user growth or engagement in countries where, even though smartphone penetration is high, due to the lack of sufficient cellular based data networks, consumers rely heavily on Wi-Fi and may not access our products regularly.
> Snapchat is free and easy to join, the barrier to entry for new entrants is low, and the switching costs to another platform are also low. Moreover, the majority of our users are 18-34 years old.
> This demographic may be less brand loyal and more likely to follow trends than other demographics.
> For example, users 25 and older visited Snapchat approximately 12 times and spent approximately 20 minutes on Snapchat every day on average in the quarter ended December 31, 2016, while users younger than 25 visited Snapchat over 20 times and spent over 30 minutes on Snapchat every day on average during the same period.
> Our Daily Active Users may not continue to grow. For example, although Daily Active Users grew by 7% from 143 million Daily Active Users for the quarter ended June 30, 2016 to 153 million Daily Active Users for the quarter ended September 30, 2016, the growth in Daily Active Users was relatively flat in the latter part of the quarter ended September 30, 2016.
