About the IGas SIP

In 2013, the Company adopted an Inland Revenue approved Share Investment Plan for all employees of the Group. The scheme is a tax efficient incentive plan pursuant to which all Company employees are eligible to subscribe for up to GBP150 (or 10% of salary, if less) worth of IGas ordinary shares per month. On a three-monthly basis, the Company matches employees' monthly subscriptions on a 1-to-1 basis and, subject to the Company having met pre-defined quarterly production targets, will increase the matching element for that quarter to 2-to-1. To receive their allocation of matching shares, employees must ordinarily remain employed by the Company for a period of 3 years.
