During the year, the Company operated the Unapproved Share Option Scheme, the Approved Share Option Scheme, the Long Term Incentive Plan and the Save As You Earn (SAYE) Share Option Scheme as described below:

Unapproved and Approved Share Option Schemes

Under these Schemes, options are granted to certain Executives and employees of the Group (excluding Executive Directors) to purchase shares in the Company at a price fixed at the average market value over the three days prior to the date of grant. For the options to vest, there must be an increase in earnings per share of at least 12% above the growth in the UK Retail Prices Index (RPI) over a three year period. Once vested, options must be exercised within ten years of the date of grant.

Long Term Incentive Plan

Vesting is dependent on two performance conditions which must be satisfied over a three year performance period commencing from the start of the financial year within which the award is granted. 50% of the award will vest dependent on the Company's TSR performance against an appropriate comparator group. 50% of the award will vest subject to a performance condition based on annual earnings per share targets. Each of the TSR and EPS elements is subject to an additional ROCE underpin. Unless the Company's ROCE is 10% or more in the final year of the performance period, the award will lapse in full.

SAYE Option Scheme

This scheme is open to all UK employees. Participants save a fixed amount of up to £500 per month for either three or five years and are then able to use these savings to buy shares in the Company at a price fixed at a 20% discount to the market value at the start of the savings period. Prior to 16 October 2012, participants were able to save for a seven year period. The SAYE options must ordinarily be exercised within six months of the completion of the relevant savings period. The exercise of these options is not subject to any performance criteria.

† Total share options exercisable at 30 June 2016 were 76,013.

The weighted average exercise price of options eligible to be exercised at 30 June 2017 was 470.86p (2016: 453.67p). For options exercised during the year, the weighted average market price at the date of exercise was 1,415p (2016: 1,206p). The weighted average remaining contractual lives of options outstanding at the Consolidated Statement of Financial Position date was four years (2016: four years).

Outstanding options on all Long Term Incentive Plan, Approved and Unapproved plans prior to 30 June 2014 were exercisable at 30 June 2017. No options issued under SAYE plans were exercisable at 30 June 2017 (2016: nil).

The fair values for shares granted under the Unapproved, Approved and SAYE Option Schemes have been calculated using the Black–Scholes option pricing model. The fair values of shares awarded under the Long Term Incentive Plan have been calculated using a Monte Carlo simulation model which takes into account the market-based performance conditions attaching to those shares. The assumptions used in calculating fair value are as follows:

Expected volatility was determined by calculating the historical volatility of the Group's share price over its entire trading history.

National Insurance contributions are payable by the Company in respect of some of the share-based payments. These contributions are payable on the date of exercise based on the intrinsic value of the share-based payments and are therefore treated as cash settled awards. The Group had an accrual at 30 June 2017 of £968,000 (2016: £842,000), of which £78,000 (2016: £65,000) related to vested options. The total charge to the Consolidated Income Statement in respect of share-based payments was:

Equity settled share-based transactions2,2682,058
Cash settled share-based transactions557328

The above charge to the Consolidated Income Statement is included within administrative expenses.
