Rating agency Standard & Poor's (S&P) is to launch an assessment service for Lloyd's syndicates in September.
Lloyd's Syndicate Assessments (LSA) will evaluate how dependent a syndicate's financial strength is on the Lloyd's Central Fund, brand, international licensing agreements and infrastructure.
LSA will replace the current S&P Lloyd's Syndicate Performance Measures (LSPM) that rank syndicates around a statistical mean of their past operating performance.
S&P will use qualitative and quantitative analysis drawn from publicly available information to determine the new ratings.
LSA is intended to bring clarity to the market, indicating which syndicates contribute more positively to the rating on Lloyd's and which syndicates contribute more negatively.
S&P noted, however, that its A (strong) rating on the Lloyd's Market will remain the principal measure of financial strength applied to all the syndicates.
S&P director Rob Jones said: "As a result of the structural changes that have taken place at Lloyd's over the past few years and a greater demand for syndicate level information, Standard & Poor's has developed LSA to complement its existing rating on the market.
"LSA will provide a clearer picture of the characteristics of syndicates operating in the Lloyd's market for those investors, intermediaries, and insureds involved."
