Separately, TheStreet Ratings Team has a "Hold" rating with a score of C+ on the stock.

The primary factors that have impacted the rating are mixed. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures and attractive valuation levels.

But the team also finds weaknesses including feeble growth in the company's earnings per share, weak operating cash flow and a generally disappointing performance in the stock itself.
