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 good cash flow from operations.

But the team also finds weaknesses including deteriorating net income, disappointing return on equity and poor profit margins.
