Recommendation

The filing reports a stock sale by an executive under a Rule 10b5-1 plan. While this is a standard practice to avoid insider trading concerns, the sale of a substantial number of shares warrants a 'hold' recommendation pending further company performance indicators. The transaction itself does not provide enough information to suggest a strong buy or sell.
