Text Block [Abstract]
Seasonality of Business	2. Seasonality of Business Historically, operating results for the second quarter of the fiscal year have not been representative of results for the entire fiscal year. Business seasonality results primarily from higher unit sales of the Company’s products in the second and third quarters versus the first and fourth quarters of the fiscal year. Fixed costs, such as depreciation expense, are not significantly impacted by business seasonality.
