Standard & Poor's revised its outlook on Teekay Shipping Corp. to positive from stable. The outlook revision reflects Teekay's consistent, solid performance, which has resulted in a gradually improving financial profile, and expectations for more predictable cash flow generation due to the purchase of contract-based shuttle tanker operator Ugland Nordic Shipping ASA. Teekay's rating reflects a favorable business position as the leading midsize ("Aframax") crude oil tanker operator in the Indo-Pacific Basin, expanded presences in the AtlanticAframax tanker market and the North Sea Shuttle tanker market, and fairly conservative financial policies. These factors are offset by significant, but carefully managed exposure to the volatile tanker spot markets.
