The acquisition means Computershare is the global leader in employee plans administration, providing a full range of employee share plan administration solutions in more than 130 countries for over 500 clients, covering around 1.4 million employee shareholders.

Stuart Crosby, Computershare's President and CEO said: "We're pleased that the acquisition has closed as planned and that we can get on with integrating the two businesses. We have a proven track record of successful integrations and I am confident that clients on both sides will see benefits in the near future. Computershare Plan Managers should be the first point of call for any business looking to review or launch an employee share plan."

The integration of HBOS EES with Computershare's business is being managed by Martyn Drake, Managing Director of the UK Employee Share Plan business, using a dedicated integration team that includes existing senior staff from Computershare UK and HBOS EES, augmented by specialist Computershare staff drawn from around the globe.
