“LME official prices and closing prices may from time to time be affected by disruption events. Where a disruption event occurs, the LME will continue to publish the values that it determines between 12.30-13.25 London time, referred to as official prices, and from 17:50 London time, referred to as closing prices.
“The LME and LME Clear will use these prices to [respectively] settle physically delivery LME contracts and margin all LME contracts, as applicable.
“However, market data users are advised that prices affected by a disruption event do not constitute formal official prices and closing prices for the purposes of any over-the-counter (OTC) contracts. Users should have regard to the fallback arrangements in their OTC contracts to determine the impact of this.”
For further clarification, subscribers should contact the LME.
