The contract types treated in this way include futures, options,swaps and certain forward sales and forward purchases contracts, and relate to both currency and commodity trading activities. Gains or losses ariseon contracts entered into for risk management purposes, optimization activity and entrepreneurial trading. They also arise on certain contracts that arefor normal procurement or sales activity for the group but that are required to be fair valued under accounting standards. Also included within sales andother operating revenues are gains and losses on inventory held for trading purposes. The total amount relating to all of these items was a net loss of$934 million (2010 $1,738 million net gain and 2009 $4,046 million net gain).Powerprice$ millionTotalEmbedded derivativesThe group has embedded derivatives relating to certain natural gas contracts. Prior to the development of an active gas trading market, UK gas contractswere priced using a basket of available price indices, primarily relating to oil products, power and inflation. After the development of an active UK gasmarket, certain contracts were entered into or renegotiated using pricing formulae not directly related to gas prices, for example, oil product and powerprices. In these circumstances, pricing formulae have been determined to be derivatives, embedded within the overall contractual arrangements that arenot clearly and closely related to the underlying commodity. The resulting fair value relating to these contracts is recognized on the balance sheet withgains or losses recognized in the income statement.All the commodity price embedded derivatives relate to natural gas contracts, are categorized in level 3 of the fair value hierarchy and are valuedusing inputs that include price curves for each of the different products that are built up from active market pricing data. Where necessary, these areextrapolated to the expiry of the contracts (the last of which is in 2018) using all available external pricing information. Additionally, where limited dataexists for certain products, prices are interpolated using historic and long-term pricing relationships.In addition, at 31 December 2010, BP was party to a collar-backed financing arrangement involving an available-for-sale investment held by thegroup. This arrangement contained an embedded derivative whose fair value was related to the equity price of the investment and was categorized inlevel 2 of the fair value hierarchy. The arrangement was terminated in 2011.Financial statementsBP Annual Report and Form 20-F 2011 227
