Subsequent Events [Abstract]
Subsequent Event	On September 24, 2015, the Company's Board of Directors authorized a stock repurchase program (the “2015 stock repurchase program”) under which the Company may, from time to time, repurchase shares of its common stock for an aggregate purchase price not to exceed the lesser of $3,500 or 250 shares. On November 1, 2017, the Company’s Board of Directors amended the Company’s 2015 stock repurchase program (the “2017 amendment”), by increasing the authorization to the lesser of $5,185 or 625 shares, exclusive of the shares previously authorized under the 2015 stock repurchase program. Under the amended authorization, share repurchases may be executed through various means, including without limitation in the open market or in privately negotiated transactions, in accordance with all applicable securities laws and regulations, including without limitation Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The extent to which the Company repurchases its shares and the timing of such repurchases will depend upon a variety of factors, including market conditions, regulatory requirements and other corporate considerations. The repurchase program does not obligate the Company to purchase any shares, and the program may be terminated, suspended, increased, or decreased by the Company’s Board of Directors in its discretion at any time.
