Debt Disclosure [Abstract]
Line of Credit and Letter of Credit Facilities	NOTE 4 – LINE OF CREDIT AND LETTER OF CREDIT FACILITIES *Line of Credit Facility* On March 31, 2017, the Company terminated its credit facility with Regions Bank. There were no loans outstanding under that facility on that date. See “Note 6 - Credit Facilities” to our financial statements included in our 2016 Annual Report on Form 10-K for a description of the material terms of the Regions Bank credit facility. The facility was terminated because the Company believes that its cash on hand, internally generated funds and other working capital are sufficient to fund its current operations and near term growth. In addition, the elimination of the facility, which was scheduled to expire in September 2017, will significantly reduce costs to the Company.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
