In April 2014, the Seoul Central District Prosecutor's Office charged Mr. Suk-chae Lee, a former chief executive officer of KT Corporation, with embezzlement and breach of fiduciary duty. Mr. Il Yung Kim, a former president of KT Corporation, was charged as a co-conspirator in the breach of fiduciary duty by Mr. Lee, and Mr. Yu-yeol Seo, a former president of KT Corporation, was charged as a co-conspirator in Mr. Lee's embezzlement. On May 30, 2017, the Supreme Court of Korea confirmed the acquittal of Mr. Lee and Mr. Kim on the charge of breach of fiduciary duty, and reversed the appellate court judgment against Mr. Lee and Mr. Seo (which had sentenced both to a suspended prison term of 18 months, on probation for two years, for allegedly creating and embezzling off-the-book funds of ?1.1 billion for personal use between 2009 and 2013) and remanded the case back to the Seoul High Court. On April 26, 2018, the Seoul High Court acquitted Mr. Lee and Mr. Seo of such charge. No indictment or charges of wrongdoing were brought against us or any of our current executives or employees in connection with such indictment of Mr. Lee, Mr. Seo, and Mr. Kim.
In March 2017, the Constitutional Court of Korea found that many Korean corporations, including us, made donations to two non-profit foundations, Mir Foundation and K-Sports Foundation, at former President Park's request. Our contributions comprised ?1.1 billion of the total ?48.6 billion given to Mir Foundation and ?700 million of the total ?28.8 billion given to K-Sports Foundation. The Constitutional Court also found that an aide of former President Park, at the direction of the former President, on several occasions asked our previous chief executive officer to hire (and later to change the employment positions of) two individuals, Mr. Dong-Soo Lee and Ms. Hye-Sung Shin. Mr. Lee was hired and later appointed as the head of a business unit in charge of our marketing and advertisement campaigns and Ms. Shin was hired to another position in the same business unit. Subsequently, the same presidential aide also requested that Mr. Lee and our other officers award advertising contracts to Playground Communications Co., Ltd. ("Playground"), an advertising agency in which Ms. Soon-sil Choi, a confidante of former President Park, effectively owns a 70% equity interest, according to the Constitutional Court. The Constitutional Court further held that the companies receiving the purported "requests" from former President Park's aide appeared to have felt immense pressure to comply with the requests and could not easily have rejected them. Playground was awarded seven advertising contracts for a total of approximately ?6.8 billion in 2016, amounting to approximately 3.7% of our annual advertising spending in 2016. In 2016, Playground recognized approximately ?517 million of income from such activities. We have not awarded additional advertising contracts to Playground since September 2016, and Mr. Lee and Ms. Shin resigned in November 2016 and May 2016, respectively.
In November 2016, the Korean Prosecutor's Office commenced investigations on former President Park and in April 2017 indicted the former President on charges of bribery, coercion and abuse of power, among others. In August 2018, the Seoul High Court sentenced the former President to a prison term of 25 years and a monetary fine of ?20 billion, having found the former President guilty on many of the charges, including the coercion charges relating to the same events underlying the Constitutional Court decisions described above: (i) the employment and changes to the employment positions of Mr. Lee and Ms. Shin at KT Corporation, (ii) the entry into advertising contracts with Playground and (iii) the donations to Mir Foundation and K-Sports Foundation by us and other Korean corporations. The prosecution appealed the appellate court's decision to the Supreme Court of Korea, which in August 2019 vacated the appellate court judgment against the former President on the bribery-related charges due to errors made in its sentencing process and remanded the case back to the Seoul High Court for retrial. In July 2020, the Seoul High Court sentenced former President Park upon retrial to a prison term of 15 years and a monetary fine of ?18 billion for the bribery-related charges and a prison term of 5 years for the other charges including abuse of power. The prosecution appealed the appellate court's decision to the Supreme Court of Korea, which in January 2021 rejected the appeal and affirmed the appellate court's judgment, which became final and conclusive. No indictment or charges of wrongdoing were brought against us or any of our executives or employees in connection with such indictment of the former President.
In January 2018, the Korean Prosecutor's Office indicted Mr. Byung-Hun Jun, a former member of the National Assembly, for charges of bribery, corruption and coercion, among others. One of the allegations was that Mr. Jun, during his term as a member of the former Science, ICT, Future Planning, Broadcasting and Communications Committee (currently the Science, ICT, Broadcasting and Communications Committee) of the National Assembly, solicited donations or financial sponsorships from various corporations, including us, to an organization where he used to serve as the president. In February 2019, the Seoul Central District Court found Mr. Jun guilty of the bribery charges and sentenced him to a prison term of five years and an aggregate monetary fine of ?375 million, guilty of abuse of authority and sentenced him to a suspended prison term of one year on probation for two years, and not guilty of the charge in connection with soliciting financial sponsorship of ?100 million from us. Both Mr. Jun and the Korean prosecution appealed the court's decision to the Seoul High Court, which in July 2020 found Mr. Jun guilty of the bribery charges, among others, and sentenced him to a suspended prison term of one year on probation for two years and an aggregate monetary fine of ?200 million and not guilty of the charge in connection with soliciting financial sponsorship of ?100 million from us. In March 2021, the Supreme Court of Korea affirmed the appellate court's judgment against Mr. Jun, which became final and conclusive. No indictment or charges of wrongdoing were brought against us or any of our executives or employees in connection with Mr. Jun's indictment.
In January 2018, the Korean police commenced an investigation in connection with the allegations that our current and former executives and employees violated the Political Funds Act of Korea, by making certain donations or providing gift cards to various lawmakers using corporate funds. This matter is currently being investigated by the Prosecutors' Office.
In March 2019, the KT New Labor Union filed criminal complaints with the Seoul Central District Prosecutor's Office against our previous chief executive officer, Mr. Chang-Gyu Hwang, alleging charges that include a criminal breach of fiduciary duty, in connection with management consulting (research and survey) contracts entered into between us and others, including certain former public officials, since November 2014. The investigation by the Prosecutor's Office is ongoing.
In April 2019, the Seoul Southern District Prosecutor's Office indicted four former executive officers, including Mr. Suk-chae Lee and Mr. Yu-yeol Seo, for charges of obstruction of business arising from allegedly engaging in a number of improper hiring during the public recruiting process of college graduates in the second half of 2012. In October 2019, the Seoul Southern District Court found the former executive officers guilty of the charges and sentenced Mr. Lee to a prison term of one year and Mr. Seo to a suspended prison term of eight months on probation for two years. Both the Prosecutor's Office and the former executive officers appealed the court's decision to the Seoul High Court, which in November 2020 sentenced Mr. Lee to a suspended prison term of one year and 6 months on probation for two years and Mr. Seo to a suspended prison term of eight months on probation for two years. In addition, the Seoul High Court found Mr. Lee guilty of bribery charges in relation to the improper hiring incident. Mr. Lee appealed the court's decisions to the Supreme Court of Korea, where the case is currently pending. No indictment or charges of wrongdoing were brought against us or any of our current executives or employees in connection with such indictment of our former executive officers.
