Dear all,
Anjam and myself had a highly productive and informative set of meetings= =20 with Andreas Barkchis of MG Metals NY on Thursday 20th July in the NY=20 office. Firstly we should say "thanks" to Andreas for being so helpful in= =20 addressing out numerous requests for information - we look forward to=20 establishing a solid working relationship with him going forward. Find below a summary of Version_1a for initial rough calculation of MG=20 Metal's VAR. Also Anjam, Kirstee (from London side) and Cantekin, Grant, Vince and mysel= f=20 (Houston side) have been working for last 2 days on the spreadsheet VAR=20 model.=20 The current status of this effort and a plan for future progress is=20 summarized in the enclosed document: =20 =20 ___________________________________________________________________________= ___ _______________________________________________________ V@R methodology for MG Metals positions Version_1a Introduction This document describes the initial rough model for calculations=20 Value-At-Risk for MG Metals. This model will be implemented in a spreadshee= t,=20 which will serve as a prototype for the RiskTrac implementation.=20 Risk factors The following positions represent most of MG Metal=01,s risk and will be co= vered=20 by Version_1a: - Base metals=01, positions including: - aluminium; - copper; - gold; - lead; - nickel; - silver; - tin; - zinc; Risk related to these positions will be quantified by simulating forward=20 prices for each metal. - Copper concentrate; Risk related to these positions will be quantified by simulating TC charges= . - Cocoa beans; Risk related to these positions will be quantified by simulating forward=20 prices for cocoa beans. Therefore these 10 curves will drive the risk: price curves for aluminium,= =20 copper, gold, lead, nickel, silver, tin, zinc and cocoa beans plus tc curve= =20 for copper concentrate. Assumptions and simplifications: - For each metal we are going to use a single price curve or all types of= =20 products (physical, financial, LME traded, Comex traded, scrap, alloy, stoc= k,=20 etc.); - Delta, gamma approach for risk on options=01, positions; =20 Components required to implement V@R model:=20 - current forward prices available from Mercur; - current implied volatilities available through Reuters; - current positions from Mercur; - history of prices required to calculate factor loadings and correlations= =20 across commodities; =20 Methodology Version_1a will be based on Risk Matrix approach. We will calculate princip= al=20 components for each metal and cocoa beans to take in account the correlatio= ns=20 along the term structure. We will also calculate the correlations across=20 commodities based on prompt month prices history for last 3 months.=20 =20 Portfolio hierarchy Each position will be assigned to one of the following portfolios under the= =20 whole portfolio AGG-METALS: - MG Metal & Commodity Corp. - MG Ltd.; - MG Metal & Commodity Company Ltd.; - MG Metall Recycling GmbH, Ffm; Under each of these sub-portfolio there will be the following sub-portfolio= s: - Comex; - Frame contract; - LME; - LME Alloy; - LME Metal Index; - Option Call; - Option Put; - Physical; - Physical Alloy; - Physical Real; - Physical Scrap; - Price Part.; - Prov. Billing; - Stock; - Stock Alloy; - Stock Comex; - Stock Physical; - Stock Scrap;
