Norsk Hydro: Primary insiders purchase shares under Long-Term Incentive program and shares to employees

Members of Hydro's Executive Leadership Team have received shares in Hydro via the Long-Term Incentive plan and purchased shares via the employee share purchase program. Long-Term Incentive plan Norsk Hydro ASA has a share-based Long-Term Incentive (LTI) program in the form of a maximum remuneration of 30 percent of the annual base salary, dependent on two equally weighted performance metrics for the President and CEO, and the other members of the Executive Leadership Team. The two performance measures are 1.) Hydro's three year average adjusted RoaCE relative to Hydro's adjusted RoaCE target, with adjusted RoaCE based on market value of equity, and 2.) Hydro's three year Total Shareholder Return (TSR) relative to a group of peers. The LTI payment is conditional on Hydro having a positive adjusted EBIT in the previous year. The participants will be required to invest the net amount after tax in Hydro shares and they must hold the shares for at least three years.
