Subsequent Events [Abstract]
Subsequent Event	SUBSEQUENT EVENT On February 21, 2018, our Board of Directors authorized an additional $15.0 million share repurchase program. Under the new program, shares of our common stock may be repurchased from time to time through February 21, 2020. Repurchases may be made in open market transactions at prevailing prices, in privately negotiated transactions, or by other means in accordance with federal securities laws. Share repurchases will be funded from existing cash balances, and repurchased shares will be retired and returned to unissued authorized shares. To date, we have not repurchased any shares under the new $15.0 million program.
