Credit Facilities [Abstract]
Credit Facilities	4.Credit Facilities We had $200,000 in short-term notes payable outstanding at June 30, 2016 and no short-term notes payable at June 30, 2015. We had approximately $365,000 of long-term debt outstanding at June 30, 2016 and no long-term debt outstanding at June 30, 2015, all of which is included in “Other Long-Term Liabilities” on our Consolidated Balance Sheet. We acquired bank debt of approximately $2,100,000 as part of the purchase of Coord3. The Company paid approximately $1,700,000 of this debt in March 2015 and the remaining balance was paid in June 2015. On October 30, 2015, we entered into an Eighth Amendment to our Amended and Restated Credit Agreement with Comerica Bank (“Credit Agreement”). The Eighth Amendment changed the Credit Agreement to an on-demand line of credit from a committed line of credit that previously required the Company to pay a commitment fee of 0.15% per annum. This Credit Agreement is cancelable at any time by either Perceptron or Comerica and any amounts outstanding would be immediately due and payable. The maximum permitted borrowings increased from $6.0 million to $10.0 million. The borrowing base was amended to add an amount equal to the lesser of 50% of eligible inventory or $4.0 million to the previous formula of the lesser of $6.0 million or 80% of eligible receivables. At June 30, 2016, our maximum borrowing under this facility was approximately $4.0 million. Proceeds under the Credit Agreement may be used for working capital and capital expenditures. Security for the Credit Agreement is substantially all of our assets held in the United States. Borrowings are designated as a Libor-based Advance or as a Prime-based Advance if the Libor-based Advance is not available. Interest on Libor-based Advances is calculated at 2.35% above the Libor Rate offered at the time for the period chosen, and is payable on the last day of the applicable period. We are required to maintain a Tangible Net Worth of at least $29.0 million, down from the $31.0 million requirement in effect prior to October 30, 2015. We were not in compliance with the Tangible Net Worth financial covenant at June 30, 2016, however a waiver was obtained from Comerica Bank on August 29, 2016. We are not allowed to pay cash dividends under the Credit Agreement. We are also required to have no advances outstanding under the Credit Agreement for 30 days (which need not be consecutive) during each calendar year. At June 30, 2016, we did not have any borrowings outstanding under the Credit Agreement, however early in the first quarter of fiscal 2017, we borrowed $1.5 million under the Credit Agreement. At June 30, 2016, our German subsidiary (“GmbH”) had an unsecured credit facility totaling €350,000 (equivalent to approximately $388,000). The facility allows €100,000 to be used to finance working capital needs and equipment purchases or capital leases. The facility allows up to €250,000 to be used for providing bank guarantees. Any borrowings for working capital needs will bear interest at 4.25%. Amounts exceeding the limit of €100,000 will bear interest at 7.15%. Any outstanding bank guarantees will bear interest at 2.0%. The GmbH credit facility is cancelable at any time by either GmbH or the bank and any amounts then outstanding would become immediately due and payable. At June 30, 2016 and 2015, GmbH had no borrowings or bank guarantees outstanding. During the second quarter of fiscal 2016, Coord3 entered into a secured credit facility totaling €200,000 (equivalent to approximately $222,000), however the facility was canceled in the fourth quarter of fiscal 2016. During the third quarter of fiscal 2016, Coord3 exercised an option to purchase the current manufacturing facility. The total remaining principal payments of €510,000 (equivalent to approximately $565,000) payable over the following 36 months at a 7.0% annual interest rate are recorded in “Short-term notes payable” and “Other Long-Term Liabilities” on our Consolidated Balance Sheet at June 30, 2016.
