text: Despite Lenovo acquiring the "Think" brand from IBM, IBM still plays a key indirect, background role in the design and production of the Think line of products. Today, IBM is responsible for overseeing servicing and repair centers, and is considered an authorized distributor and refurbisher of the Think line of products produced by Lenovo.
  IBM also acquired an 18.9% share of Lenovo in 2005 as part of Lenovo's purchase of IBM's personal computing division. In the years following the deal, IBM sold their stake in Lenovo, with a final sale in 2011 completing their divestment.
  Mary Ma, Lenovo's chief financial officer from 1990 to 2007, was in charge of investor relations. Under her leadership, Lenovo successfully integrated Western-style accountability into its corporate culture. Lenovo's emphasis on transparency earned it a reputation for the best corporate governance among mainland Chinese firms. While Hong Kong-listed firms were only required to issue financial reports twice per year, Lenovo followed the international norm of issuing quarterly reports. Lenovo created an audit committee and a compensation committee with non-management directors. The company started roadshows twice per year to meet institutional investors. Ma organized the first-ever investor relations conference held in mainland China. The conference was held in Beijing in 2002 and televised on China Central Television (CCTV). Liu and Ma co-hosted the conference and both gave speeches on corporate governance.
