COMMITMENTS AND CONTINGENCIES

U.S. Government Cost Claims

From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed costs, plus, at times, penalties and interest. When such findings are presented, the company and U.S. government representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s estimated exposure for such potential disallowed costs. Such provisions are reviewed periodically using the most recent information available. The company believes it has adequately reserved for disputed amounts that are probable and reasonably estimable, and that the outcome of any such matters would not have a material adverse effect on its unaudited condensed consolidated financial position as of June 30, 2018, or its annual results of operations and/or cash flows.

Environmental Matters

The table below summarizes management’s estimate of the range of reasonably possible future costs for environmental remediation, the amount accrued within that range, and the deferred costs expected to be recoverable through overhead charges on U.S. government contracts as of June 30, 2018 and December 31, 2017:



$ in millions	Range of Reasonably Possible Future Costs⁽¹⁾	Accrued Costs⁽²⁾		Deferred Costs⁽³⁾
June 30, 2018	$453 - $836	$	463	$	236
December 31, 2017	405 - 792	410		207


⁽¹⁾	Estimated remediation costs are not discounted to present value. The range of reasonably possible future costs does not take into consideration amounts expected to be recoverable through overhead charges on U.S. government contracts.

⁽²⁾As of June 30, 2018, $155 million is recorded in other current liabilities and $308 million is recorded in other non-current liabilities.

⁽³⁾As of June 30, 2018, $79 million is deferred in prepaid expenses and other current assets and $157 million is deferred in other non-current assets. These amounts are evaluated for recoverability on a routine basis.

As a result of the Merger, we assumed certain environmental remediation liabilities that are included in the accrued costs above, along with the related deferred costs expected to be recoverable on U.S. government contracts.

Although management cannot predict whether new information gained as our environmental remediation projects progress, or as changes in facts and circumstances occur, will materially affect the estimated liability accrued, except with respect to Bethpage, we do not anticipate that future remediation expenditures associated with our currently identified projects will have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2018, or its annual results of operations and/or cash flows. With respect to Bethpage, as described in Note 7, we cannot at this time estimate the range of reasonably possible additional future costs that could result from potential changes to remediation standards or requirements to which we are subject.

Financial Arrangements

In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial banks and surety bonds issued principally by insurance companies to guarantee the performance on certain obligations. At June 30, 2018, there were $395 million of stand-by letters of credit and guarantees and $211 million of surety bonds outstanding.

Indemnifications

The company has provided indemnification for certain environmental, income tax and other potential liabilities in connection with certain of its divestitures. The settlement of these liabilities is not expected to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2018, or its annual results of operations and/or cash flows.

Operating Leases

Rental expense for operating leases for the three and six months ended June 30, 2018 was $81 million and $173 million, respectively, and was $65 million and $154 million for the three and six months ended June 30, 2017, respectively. These amounts are net of immaterial amounts of sublease rental income.

Credit Facilities

In December 2016, a subsidiary of the company entered into a two-year credit facility, with two additional one-year option periods, in an aggregate principal amount of £120 million (the equivalent of approximately $159 million as of June 30, 2018) (the “2016 Credit Agreement”). The company exercised the first option to extend the maturity to December 2019. The 2016 Credit Agreement is guaranteed by the company. At June 30, 2018, there was £90 million (the equivalent of approximately $119 million) outstanding under this facility, which bears interest at a rate of LIBOR plus 1.10 percent. All of the borrowings outstanding under this facility mature less than one year from the date of issuance, but may be renewed under the terms of the facility. Based on our intent and ability to refinance the obligations on a long-term basis, substantially all of the borrowings are classified as non-current.

The company also maintains a five-year unsecured credit facility in an aggregate principal amount of $1.6 billion that matures in July 2020. At June 30, 2018, there was no balance outstanding under this facility.

At June 30, 2018, the company was in compliance with all covenants under its credit agreements.

Commercial Paper

In May 2018, the company commenced a commercial paper program that serves as a source of short-term financing. Under this program, the company may issue up to $750 million of unsecured commercial paper notes. The commercial paper notes outstanding have original maturities of 90 days or less from the date of issuance. At June 30, 2018, there were $249 million of outstanding short-term commercial paper borrowings at a weighted-average interest rate of 2.46 percent.
