Debt trading poll 2009: Methodology
Votes are sorted in descending order of stated total trading volumes and weighted as follows:
Factor of 4 applied to voters in first (top) quartile of trading volumes Factor of 3 applied to voters in second quartile Factor of 2 applied to voters in third quartile Factor of 1 (unity) applied to voters in fourth quartile
Overall ranking by market share: based on the total volume of business placed annually with each bank. We asked respondents to estimate the proportion of their total annual debt trading business placed with their five top counterparties. Total business placed with each service provider across all questionnaires received is then divided by total business on all questionnaires.
