Subject: parking for prior periods - i am not sure if you need to handle this using the instructions below - or if for prior months only - if you would be allowed to create a cashout ticket to clear out any prior period imbalances . your controller and volume management ( kathy kelly ) should make this call . kim and david can brain check me on this - but i think this is how parking should be done ; however , please verify with west or east desk economics to ensure accuracy / consistency . parking procedures create a storage deal in sitara - service type : parking use this service deal to path to a storage account in unify - this way you have accounted for the gas in unify inject into storage account withdrawal from storage account ( when you do the opposite of parking - withdrawal first - it is called a " loan " ) create two economic deals in sitara - exchange deal create an internal buy and sell of physical gas for economics and position purposes - ( no invoices - fake 3 rd party ) exchange deal - sell to cpr pipeline exchange ( parking gas ) buy from cpr pipeline exchange ( getting gas back ) within the month parking - no money exchanges hands - except any service fees which can be recorded on the storage deal . sell to cpr pipeline exchange ( parking gas ) - price = $ 0 buy from cpr pipeline exchange ( getting gas back ) price = $ 0 when the deal crosses a month - if you keep the risk within the desk - in the short term you record a big loss - sell at $ 0 - and the next month you record a big gain - buy at $ 0 . to manage this - usually the cash desk swaps out the time risk to a storage financial book - who will pick up the time spread loss and offsetting gain - as this book captures forward value . when you are adjusting your physical injections ( parking ) within the month - you will need to adjust your swaps too - which will adjust the p & l for the time spread accordingly - otherwise you will have liquidation problems . period 1 - sell to cpr pipeline exchange ( parking gas ) - price = $ 0 swap to firm book for index + mid period 2 - buy from cpr pipeline exchange ( getting gas back ) price = $ 0 swap to firm book for index + mid
