The board has further implemented a long-term incentive plan exclusively in Turquoise Hill share-based compensation to align executives' compensation with the interests of all shareholders, adopted formal shareholding guidelines requiring named executive officers and the independent directors to accumulate a meaningful equity interest in Turquoise Hill over a five-year period and three-year period, respectively, as well as implementing a formal shareholder engagement policy. "Like SailingStone, the board wants to see Oyu Tolgoi's underground mine built safely and quickly. And like SailingStone, the board is frustrated with the performance of Turquoise Hill's shares," the company, chaired by independent director Peter Gillin, said. The other three independent directors are Russ Robertson, James Gill and Maryse Saint - Laurent. The underground mine at Oyu Tolgoi has faced several delays.
