|Members of the Parent's executive management team and certain other employees (together defined as key management personnel) are eligible to receive payment under a cash settled share based payment scheme. The scheme is defined as follows:
An incentive scheme for key management personnel of the Parent was implemented on 15 May 2009. This is a cash-settled share-based payment scheme covering a three-year period. Subsequently, each year on the 15th of May, a new tranche of the scheme has been issued and covers a period of three years from the issue date.
Key management personnel are eligible to receive a bonus payment at the end of the three year period of the scheme, the sum of which is determined by the total return on a notional number of allocated shares. The return is calculated as the sum of dividends paid by the Parent plus the increase in share price over the period. Payment is only made if a minimum return, set by the Board, is met. Additionally the scheme has a set maximum return above which no increase in the bonus is received by the participants. The total return is calculated for a three year period commencing on the 15th of May with reference to the average share price over the ten days prior to the scheme closing.
The fair value of the liability at 31 March 2013 has been determined by reference to the Parent's current share price and expected dividends and share price movements with comparison to the share price at the start of the relevant period and adjusted to reflect the present value of these future expected cash flows.
For the year ended 31 March 2013 the total expense recognised in the income statement was $89,000 (2012: $(43,000)) and the liability recognised in the statement of financial position as at 31 March 2013 is $99,000 (2012: $10,000).
