Text Block [Abstract]
401 (K) Plan	Eligible employee participants are automatically enrolled at 3% of compensation unless a participant elects an alternative deferral percentage limited to dollar amount of $18,500 in 2018 or elects not to defer under the Plan.

General description of deferred compensation arrangements. Deferred compensation represents currently earned compensation that, under the terms of a profit-sharing, rabbi trust, pension, employee contract, or equity-based (including stock or unit option) plan, is not actually paid until a later date and is therefore not taxable until that date. May also include some split-dollar life insurance arrangements. This type of arrangement is usually made to help employees postpone paying taxes on the income and also to retain employees longer.
