Business Report (From January 1, 2011 to December 31, 2011)

1. Current Status of the Corporate Group (1) Business summary for the current fiscal year  Outline and results of business operations The global economic activities for the current consolidated fiscal year remained at a relatively low level primarily due to the European debt crisis, and economic recovery also remained at a slow pace. Asian region, such as and India, which have been leading the global economy are still expanding mainly due to strong domestic demands, but there appears to be the need to monitor the trends of real estate and commodity prices and the exporting business to the European and American regions. In the United States of America, the economy has started to show a sign of recovery including a decrease in unemployment rates towards the end of the year, but it continues to experience tension caused by the turmoil in the financial and capital markets in the European region. European economy was exposed to the risk of a sharp drop because of the confusion in the capital market, negative impact of fiscal tightening, and concerns over debt problems of certain countries. In Japan, due to the Great East Japan Earthquake and the nuclear power plant disaster, the economic activities, mostly in eastern Japan, have been partially paralyzed. Coupled with the rapid appreciation of yen and concerns about the slowing global economy, the outlook of domestic economy and individual consumption is uncertain.

Under such economic environment described above, the Group is engaged in primarily online game business, as well as mobile game business and other businesses, and has been focusing on providing high quality services to wide range of customers and on acquiring excellent contents to accommodate diversifying needs of users through updating existing game titles and publishing new game titles.

As a result of our efforts, we recorded Net sales of ¥87,612 million (an increase of 25.6% year-on-year); Operating income of ¥38, 249 million (an increase of 26.7% year-on-year); Ordinary income of ¥36,905 million (an increase of 29.6% year-on-year); and, Net income of ¥25, 755 million yen (an increase of 19.0% year-on-year) for the consolidated fiscal year ended December 31, 2011.

Performance results by reportable segments presented as Net sales to third party customers are as follows:

- 3 - i) Japan In Japan, major updates of leading existing game titles, such as “Maple Story,” “Dungeon and Fighter,” and “Tales Weaver,” contributed to steady performance. In addition, our expansion into the new sector of devices and platforms such as smart phones and tablets, and publishing new game titles such as “Mabinogi: Heroes” contributed to Net sales of ¥13,012 million and Segment income of ¥2,202 million despite IPO-related expenses. ii) Korea In Korea, continuing increases in Royalty revenue from publishing “Dungeon and Fighter” in China and successful updates of existing game titles such as “Maple Story” and “Dungeon and Fighter” Contributed to Net sales of ¥63,173 million and Segment income of ¥33,741 million despite the capital expenditure such as setting up a new customer center. The impact of the substantial appreciation of Japanese yen against Korean won was mostly offset by high rate of growth and did not have a significant negative impact on earnings. iii) China In China, Net sales and Segment income were ¥3,146 million and ¥2,028 million, respectively, due to the increase in Consulting revenue resulting from an increase in number of online game users against the backdrop of the internet adoption. iv) North America North America segment recorded Net sales of ¥6,210 million as a result of steady performance of the existing game titles as well as contributions from our new game title “Dragon Nest” and our first Facebook-platform game title “Maple Story Adventure.” However, aggressive marketing activities such as participation in E3 (Note) and advance investments including recruitment activities for the purpose of strengthening service functions resulted in Segment loss of ¥274 million. v) Other In other segments, primarily due to the favorable performance of the existing game titles in European countries, Net sales and Segment income amounted to ¥2,071 million and ¥478 million, respectively.

- 4 - (Note) E3 refers to the Electronic Entertainment Exposition which is a computer game-related exhibition held in the United States.
