Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Letters of Credit, Surety Bonds and Bank Guarantees Certain customers require us to post letters of credit or surety bonds which assure that we will perform under the terms of our contract. In the event of default, the counterparty may demand payment from the bank under a letter of credit or performance by the surety under a bond. To date, there have been no significant expenses related to either letters of credit or surety bonds for the periods reported. We were contingently liable for letters of credit of $22.3 million as of June 30, 2018. We also had surety bonds totaling $168.3 million that were outstanding, with additional bonding capacity of $581.7 million available, at June 30, 2018. Additionally, we have a $6.6 million facility agreement (Facility Agreement) between Powell (UK) Limited and a large international bank. This Facility Agreement provides Powell (UK) Limited the ability to enter into bank guarantees as well as forward exchange contracts and currency options. At June 30, 2018, we had outstanding guarantees totaling $3.2 million under this Facility Agreement and amounts available under this Facility Agreement were $3.4 million. The Facility Agreement provides for financial covenants and customary events of default, and carries cross-default provisions with our U.S. Revolver. If an event of default (as defined in the Facility Agreement) occurs and is continuing, per the terms and subject to the conditions set forth therein, obligations outstanding under the Facility Agreement may be accelerated and declared immediately due and payable. As of June 30, 2018, we were in compliance with all of the financial covenants of the Facility Agreement. Litigation We are involved in various legal proceedings, claims and other disputes arising from our commercial operations, projects, employees and other matters which, in general, are subject to uncertainties and in which the outcomes are not predictable. Although we can give no assurances about the resolution of pending claims, litigation or other disputes and the effect such outcomes may have on us, management believes that any ultimate liability resulting from the outcome of such proceedings, to the extent not otherwise provided or covered by insurance, will not have a material adverse effect on our consolidated financial position or results of operations or liquidity. Liquidated Damages Certain of our customer contracts have schedule and performance obligation clauses that, if we fail to meet them, could require us to pay liquidated damages. Each individual contract defines the conditions under which the customer may make a claim against us. As of June 30, 2018, our exposure to possible liquidated damages was $2.6 million, of which approximately $1.6 million is probable. Based on our actual or projected failure to meet these various contractual commitments, $1.5 million has been recorded as a reduction to revenue. Of the $1.5 million recorded as a reduction to revenue, approximately $1.0 million was recognized in prior periods. We will attempt to obtain change orders, contract extensions or accelerate project completion which may resolve the potential for any unaccrued liquidated damage. Should we fail to achieve relief on some or all of these contractual obligations, we could be required to pay additional liquidated damages, which could negatively impact our future operating results.
