Stock Based Compensation [Line Items]
Number of sharea authorized	100,000
Expiration period	20 years
Expiration period description	The Compensation Committee of the Board of Directors recommended to the Board amendments to the 2010 Incentive Plan which would amend Section 1.3 to extend the term from ten years to sixteen years, and Section 6.4 to change "tenth (10th) anniversary date" to "twentieth (20th) anniversary date". This would increase the term of the 2010 Incentive Plan to twenty years (expiring in February 2030 instead of February 2020) and also permit the existence of options with a term longer than ten years. The purpose of the amendment to the term is to extend its existence as our only incentive plan.
