We are subject to the rating of our content by the Entertainment Software Rating Board and similar agencies. Failure to obtain our target ratings for our products could negatively impact our sales.
The Entertainment Software Rating Board (the ESRB) requires game publishers to provide consumers with ratings information, including information relating to violence, nudity, or sexual content contained in software titles,
and imposes significant penalties for noncompliance. Certain countries have also established similar rating systems as prerequisites for product sales in those countries. In some instances, we may be required to modify our products to comply with the requirements of rating systems, which could delay or disrupt the release of our products, or we may be prevented from selling them altogether in certain territories. Our software titles receive a rating from the ESRB of Everyone (age 6 and older), Everyone 10+ (age 10 and older), Teen (age 13 and over), or Mature (age 17 and over). Many of our titles have received an Mature rating. None of our titles have received the Adults Only rating (18 and over). We believe that we comply with rating systems and properly display the ratings and content descriptions received for our titles. If we are unable to obtain the ratings we have targeted for our products as a result of changes in the ESRBs ratings standards or for other reasons, including the adoption of legislation in this area, our business and prospects could be negatively affected.
