## 15 COMMODITY DERIVATIVE PRODUCT ARCHITECTURE

NOTE: Some refactoring work for SettlementPeriods are being considered for the next draft.

### 15.1 Introduction

This section provides a detailed description of the product architecture for commodity derivatives. FpML transparency view currently provides support for cash-settled commodity swaps (fix/float), cash settled commodity options, bullion forwards, and physically settled natural gas, oil, electricity, and coal swaps.

### 15.2 Commodity Underlyer

The 'commodity' underlyer identifies the market price on which the OTC contract is written. The structure of the 'commodity' underyer follows the ISDA Commodity Reference Price Framework. FpML defines a number of global elements in the FpML schema for various types of assets The 'commodity' underlyer follows the same model.

The 'instrumentId' and the 'description' elements are derived from the IdentifiedAsset type, which is used by multiple underlyers. The 'instrumentId' contains the unique identifier for the asset, and is intended to hold a Commodity Reference Price in the format set out by ISDA in the 1993 or 2005 Commodity Definitions. However, a CUSIP, ISIN, or any other identifier could also be used. The 'description' contains the name of the asset.

The following sequence of elements is optional and they are specified only in the event that no ISDA Commodity Reference Price or other standard identifier for a commodity 'index' exists.

| commodityBase-A coding scheme value to identify the base type of the commodity being traded. Where possible, this should follow the naming convention used in the 2005 ISDA Commodity Definitions. For example, 'Oil'.

specifiedPrice-The 'specified Price' describes the nature of the underlying price that is observed. It must be be stated in the underlyer definition as it is not defined in the Commodity Reference Price. Example values of 'specifiedPrice' are 'Settlement' (for a futures contract) and 'WeightedAverage' (for some published prices and indices).

deliveryDates-The 'deliveryDates' element is applicable for a Commodity Reference Price that references a listed future contract (e.g. The Delivery Date is a NearbyMonth).

### 15.3 commoditySwap

CommoditySwap-The commodity swap product model is designed to support fixed-float swaps, float-float swaps, fixed vs. physical swaps, float vs. physical swaps as well as, weather specific swaps. Its design is fully compatible with other FpML products and the product reuses standard common types.

As with all products in FpML, commodity swaps are accessed through a global element, 'commoditySwap', which substitutes for the 'product' element used in trade structures. The following diagram outlines the product structure.

The 'commoditySwap' structure defines parameters for product-related information (e.g. dates, rates, underlying commodity, price source, etc.). Other trade-related information (e.g. trade date, identifiers, legal documentation, etc.) is held in the containing 'trade' structure.

The 'commoditySwapLeg' element is placeholder within commoditySwap structure for the actual commoditySwap swap legs (e.g. 'fixedLeg' and 'floatingLeg'). The 'weatherLeg' is modeled as a choice to 'commoditySwapLeg' because weather index transactions are strictly financially-settled transaction and always structured with two legs, each of which is a 'weatherLeg'.

The 'fixedLeg', 'floatingLeg', 'weatherLeg' elements contain the details of any scheduled cash payments or exchanges during the life of the instrument and are described later. A transparency view commodity swap contains two legs, one fixed and one floating, or two weather legs. More complex instruments are considered customized and are not fully covered in transparency view; for these, the "nonStandardTerms" indicator should be set to "true".

Physical settlement of swaps is represented using 'coalPhysicalLeg', 'electricityPhysicalLeg', 'gasPhysicalLeg', 'oilPhysicalLeg', 'environmentalPhysicalLeg' paired with 'fixedLeg' or 'floatingLeg' - see details in the Physical Leg section.

15.3.2 fixedLeg

FixedPriceLeg-Fixed Price Leg of a Commodity Swap. It defines schedule of fixed payments associated with a commodity swap.

| CommodityCalculationPeriods.model-The different options for specifying the Calculation Periods. CommodityFixedPrice.model-The different options for specifying the Fixed Price. CommodityNotionalQuantity.model-The different options for specifying the Notional Quantity. A flat notional for the term of the contract may be specified, or else the Notional Quantity per Calculation Period. In the latter case, there must be a notional quantity step specified for each Calculation Period, regardless of whether the Notional Quantity changes or remains the same between periods. CommodityFreightFlatRate.model-The Flat Rate, applicable to Wet Voyager Charter Freight Swaps.

- The 'fixedPrice' structure defines the price for a given unit of the underlying commodity where that price is fixed for the life of the trade.
- The 'totalPrice' structure specifies the total amount of all fixed payments due during the term of the trade.
- The total notional quantity and quanity units also must be supplied.

15.3.3 floatingLeg

FloatingPriceLeg-Floating Price Leg of a Commodity Swap. Each 'floatingLeg' defines a series of financial payments for a commodity the value of which is derived from a floating price such as an exchange or an index publication.

In the latter case, there must be a notional quantity step specified for each Calculation Period, regardless of whether the Notional Quantity changes or remains the same between periods. calculation-Defines details relevant to the calculation of the floating price.Defines details relevant to the calculation of the floating price.

Two structures distinguish the 'floatingLeg' from the 'fixedLeg': the existence of the 'commodity' underlyer (see description above at the Commodity Underlyer section) and the 'calculation' structure within the floating leg.

##### 15.3.3.2 calculation

The 'calculation' structure captures details relevant to the calculation of the floating price.

The structure is defined by the following elements:

In some trades, there may be a spread-The spread over or under the Commodity Reference Price for this leg of the trade. spreadPercentage-The spread percentage over or under the Commodity Reference Price for this leg of the trade.

##### 15.3.3.2.1 pricingDates

15.3.4 weatherLeg

WeatherLeg-A weather leg of a Commodity Swap defines Weather Index Swap transactions. Weather Index Swap transactions are OTC derivative transactions which settle financially based on an index calculated from observations of temperature, precipitation and other weather-related measurements at weather stations throughout the world. Sub-Annex C of the 2005 ISDA Commodity Definitions provides definitions and terms for a number of types of weather indices. These indices include: HDD (heating degree days), CDD (cooling degree days), CPD (critical precipitation days). Weather Index Swap transactions result in a cash flow to one of the two counterparties each Calculation Period depending on the relationship between the Settlement Level and the Weather Index Level. A Weather Index swap transaction always consists of a commodity swap element as a parent to two weatherLeg elements.
Weather Index transaction = weatherLeg/weatherLeg.
