We may not accurately predict the amount of bandwidth necessary to sustain our business.
Our online gaming businesses are dependent on the availability of sufficient Internet bandwidth. An increase in the price of bandwidth could have an adverse effect on operating margins since we may not be able to increase our prices or subscriber levels to compensate for such costs. Because of the importance of the MMORPG business, our ability to access adequate bandwidth to support our business is critical. To secure bandwidth access, we have entered into arrangements with several bandwidth providers and entered into long-term contracts with some of them to secure future bandwidth capacity. If the price of bandwidth were to decrease, our contractual commitment to pay higher prices could affect our ability to compete with other video game producers.
Conversely, since we purchase additional bandwidth based on anticipated growth, our bandwidth capacity is sometimes larger than necessary to sustain our existing needs. If our projected online business growth is delayed or does not occur, we will incur larger bandwidth expenses than necessary. If we underestimate the amount of bandwidth that our online business requires, and our purchased bandwidth capacity is insufficient to meet demand, our business and reputation may suffer.
