In less active markets data is obtained from less frequent market transactions, broker quotes and through extrapolationand interpolation techniques. Where observable prices or inputs are not available, o<strong>the</strong>r relevant sources of information such ashistorical data, fundamental analysis of <strong>the</strong> economics of <strong>the</strong> transaction and proxy information from similar transactions are used.These models are continually reviewed and assessed to ensure that <strong>the</strong> best available data is being utilised in <strong>the</strong> determination offair value.• O<strong>the</strong>r liabilitiesShort positions or long positions in equities arise in trading activities where equity shares, not owned by <strong>the</strong> group, are sold in <strong>the</strong>market to third parties. The fair value of <strong>the</strong>se instruments is determined by reference to <strong>the</strong> gross short/long position valued at <strong>the</strong>offer rate.Where <strong>the</strong> group has assets and liabilities with offsetting market risks, it may use mid-market prices as a basis for establishing fairvalues for <strong>the</strong> offsetting risk positions and apply <strong>the</strong> bid or asking price to <strong>the</strong> net open position, as appropriate.
