“Considering the weak economic conditions, I am relatively pleased with our top line growth,” O’Dell said. “I am particularly disappointed with the second half results during which margins were challenged due to the weak economic environment, higher accident and health plan expenses at a time we were investing in servicing new lanes associated with our geographic expansions. While the near-term economic environment remains challenging, I am cautiously optimistic about 2008. We believe our focused strategy of building density in our recently expanded network and numerous engineered cost initiatives will improve margins and shareholder value.”
