The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, reasonable valuation levels and expanding profit margins. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, weak operating cash flow and a generally disappointing performance in the stock itself.
