Xavier Rolet has invested £158,000 in London Stock Exchange shares. The London Stock Exchange's chief executive has bought the shares for his US pension fund. He acquired 23,000 shares at 689p a share. These are the first shares he has bought since becoming chief executive. Rolet is participating in the London Stock Exchange Long Term Incentive Plan so when he buys shares he receives a matching award of shares via the LTIP. Rolet has to remain employed by the exchange for three years and remain a holder of the original shares. Certain corporate performance targets need to be satisfied for the shares to be issued. The London Stock Exchange's decision to cut its dealing tariffs helped it increase market share in the core cash equities business, but meant a mixed performance overall in the last three months. Revenues rose by 1% to £158.2m in the three months to June and by 3% quarter-on-quarter. Total income in the three months to June rose by 2% to £166m and by 5% quarter-on-quarter.Top Director BuysAgua Terra Limited (ATE) Director name: Mr Peter George EconomidesAmount purchased: 1,428,244 @ € 1.45 Value: € 2,070,954Ashmore Group (ASHM) Director name: Mr Graeme DellAmount purchased: 283,697 @ 317.24p Value: £900,000London Stock Exchange Group (LSE) Director name: Mr Xavier RoletAmount purchased: 23,000 @ 689.00p Value: £158,470Arbuthnot Banking Group (ARBB) Director name: Mr Paul Anthony LynamAmount purchased: 10,000 @ 405.00p Value: £40,500UTV Media (UTV) Director name: Mr Norman McKeownAmount purchased: 22,400 @ 128.55p Value: £28,795Top Director SellsAgua Terra Limited (ATE) Director name: Mr Markos Andreas KashiourisAmount sold: 1,428,244 @ € 1.45 Value: € 2,070,954
