Equity [Abstract]
Shareholders' Equity	10. SHAREHOLDERS’ EQUITY: In August 2017, our Board of Directors approved a new share repurchase plan allowing our company to repurchase up to 2,000,000 shares of our common stock through September 30, 2019. Under the plan, we may buy back common stock from time to time in the open market or in privately negotiated blocks, dependent upon various factors, including price and availability of the shares, and general market conditions. Through September 30, 2018 we had purchased an aggregate of 4,470,731 shares of common stock under the current and historical share repurchase plans for an aggregate purchase price of approximately $75.3 million. As of September 30, 2018, approximately 342,885 shares remained available for future purchases under the share repurchase program.

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.
