Letters of Credit and Bonds Certain customers require us to post bank letter of credit guarantees or performance bonds issued by a surety. These guarantees and performance bonds assure that we will perform under the terms of our contract.

To date, there have been no significant expenses related to either letters of credit or performance bonds for the periods reported.

We also had performance and maintenance bonds totaling $303.2 million that were outstanding, with additional bonding capacity of $446.8 million available, at June 30, 2015. We have a $15.7 million facility agreement (Facility Agreement) between Powell (UK) Limited and a large international bank. This Facility Agreement provides Powell (UK) the ability to enter into bank guarantees as well as forward exchange contracts and currency options. At June 30, 2015, we had outstanding guarantees totaling $6.4 million under this Facility Agreement. Amounts available under this Facility Agreement were $9.3 million as of June 30, 2015. The Facility Agreement provides for financial covenants and customary events of default, and carries cross-default provisions with our Amended Credit Facility. 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 in the Facility Agreement, obligations outstanding under the Facility Agreement may be accelerated and may become or be declared immediately due and payable. As of June 30, 2015, 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 in the ordinary course of business which, in general, are subject to uncertainties and in which the outcomes are not predictable. Although we can give no assurance about the outcome of pending or threatened litigation 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 subject us to liquidated damages. Each individual contract defines the conditions under which the customer may make a claim against us. We have had potential exposure for liquidated damages in the past, but in most instances they were not asserted by the customer. As of June 30, 2015, our exposure to possible liquidated damages is $6.7 million, of which approximately $2.0 million is probable. Based on our actual or projected failure to meet these various contractual commitments, $0.8 million has been recorded in our financial statements. We believe that we will be successful in obtaining change orders or contract extensions that should resolve the potential for any unaccrued liquidated damages; however, should we fail to achieve relief on some or all of these contractual obligations, we could be subject to additional liquidated damages which could impact our future operating results.

Long-Term Debt

See Note E herein for discussion of our long-term debt.

Letters of Credit and Bonds

Certain customers require us to post bank letter of credit guarantees or performance bonds issued by a surety. These guarantees and performance bonds 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 performance bond. To date, there have been no significant expenses related to either letters of credit or performance bonds for the periods reported. We were contingently liable for secured and unsecured letters of credit of $18.1 million as of June 30, 2015. We also had performance and maintenance bonds totaling $303.2 million that were outstanding, with additional bonding capacity of $446.8 million available, at June 30, 2015.

We have a $15.7 million facility agreement (Facility Agreement) between Powell (UK) Limited and a large international bank. This Facility Agreement provides Powell (UK) the ability to enter into bank guarantees as well as forward exchange contracts and currency options. At June 30, 2015, we had outstanding guarantees totaling $6.4 million under this Facility Agreement. Amounts available under this Facility Agreement were $9.3 million as of June 30, 2015.

The Facility Agreement provides for financial covenants and customary events of default, and carries cross-default provisions with our Amended Credit Facility. 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 in the Facility Agreement, obligations outstanding under the Facility Agreement may be accelerated and may become or be declared immediately due and payable. As of June 30, 2015, 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 in the ordinary course of business which, in general, are subject to uncertainties and in which the outcomes are not predictable. Although we can give no assurance about the outcome of pending or threatened litigation 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 subject us to liquidated damages. Each individual contract defines the conditions under which the customer may make a claim against us. We have had potential exposure for liquidated damages in the past, but in most instances they were not asserted by the customer. As of June 30, 2015, our exposure to possible liquidated damages is $6.7 million, of which approximately $2.0 million is probable. Based on our actual or projected failure to meet these various contractual commitments, $0.8 million has been recorded in our financial statements. We believe that we will be successful in obtaining change orders or contract extensions that should resolve the potential for any unaccrued liquidated damages; however, should we fail to achieve relief on some or all of these contractual obligations, we could be subject to additional liquidated damages which could impact our future operating results.
