Cash and cash equivalents excluded $23.9 million and $29.5 million of restricted cash at June 30, 2020 and September 30, 2019, respectively, which for purposes of our consolidated statements of cash flows, is included in cash, cash equivalents and restricted cash.

Inventories

Inventories consist of the following (in thousands):

	June 30,		September 30,
	2020		2019

Net inventories	$	151,613	$	106,794

At June 30, 2020, work in process and inventoried costs under long-term contracts included approximately $7.7 million in costs incurred outside the scope of work or in advance of a contract award compared to $5.8 million at September 30, 2019. We believe it is probable that we will recover the costs inventoried at June 30, 2020, plus a profit margin, under contract change orders or awards within the next year.

Costs we incur for certain U.S. federal government contracts include general and administrative costs as allowed by government cost accounting standards. The amounts remaining in inventory totaled $0.4 million and $0.5 million at June 30, 2020 and September 30, 2019, respectively.

Deferred Compensation Plan

We have a non-qualified deferred compensation plan offered to a select group of highly compensated employees. The plan provides participants with the opportunity to defer a portion of their compensation in a given plan year. The liabilities associated with the non-qualified deferred compensation plan are included in other noncurrent liabilities in our Condensed Consolidated Balance Sheets and totaled $10.9 million at June 30, 2020 and $11.0 million at September 30, 2019.

In the past we have made contributions to a rabbi trust to provide a source of funds for satisfying a portion of these deferred compensation liabilities. The total carrying value of the assets set aside to fund deferred compensation liabilities totaled $6.4 million at each of June 30, 2020 and September 30, 2019, and were comprised entirely of life insurance contracts. The carrying value of the life insurance contracts is based on the cash surrender value of the policies. Changes in the carrying value of the deferred compensation liability and changes in the carrying value of the assets held in the rabbi trust are reflected in our Condensed Consolidated Statements of Operations.
