(a)	Revenues are attributed to individual countries based on the location of the facility generating the revenue.


(b)	Includes Mexico.


(c)	The Company has adopted the new revenue recognition standard utilizing the modified retrospective transition method, including use of practical expedients. Comparative information has not been restated and continues to be reported under U.S. GAAP in effect for those periods. See Note 2, Recently Adopted and Recently Issued Accounting Standards for additional information.

The Company may receive payments in advance of earning revenue, which are treated as Advances on contracts on the Consolidated Balance Sheets. The Company may recognize revenue in advance of being able to contractually invoice the customer, which is treated as Contract assets on the Consolidated Balance Sheets. Contract assets are transferred to Trade accounts receivable, net when right to payment becomes unconditional. Contract assets and Contract liabilities are reported as a net position, on a contract-by-contract basis, at the end of each reporting period. These instances are primarily related to the Harsco Rail Segment.

The Company had Contract assets totaling $31.2 million at December 31, 2019 and $12.1 million at December 31, 2018. The increase is due principally to additional contract assets recognized in excess of the transfer of contract assets to accounts receivable. The Company had Advances on contracts totaling $60.3 million at December 31, 2019 and $67.1 million at December 31, 2018. The decrease is due principally to the recognition of revenue on previously received advances on contracts in excess of receipts of new advances on contracts during the period, primarily in the Harsco Rail Segment. During the year ended December 31, 2019, the Company recognized approximately $67 million of revenue related to amounts previously included in Advances on Contracts. Additionally, during the year ended December 31, 2019, the Company recognized decreased revenue of approximately $1 million, in the Harsco Rail Segment, related to performance obligations partially satisfied in prior periods, resulting from the changes in estimated costs for certain projects where revenue is recognized on an over time basis.

At December 31, 2019, the Harsco Environmental Segment had remaining, fixed, unsatisfied performance obligations, where the expected contract duration exceeds one year totaling $152.5 million. Of this amount, $43.5 million is expected to be fulfilled by December 31, 2020, $35.0 million by December 31, 2021, $33.8 million by December 31, 2022, $20.4 million by December 31, 2023 and the remainder thereafter. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year. The increase from September 30, 2019 is primarily related to a three-year contract extension related for one of the impacted locations.

At December 31, 2019, the Harsco Rail Segment had remaining, fixed, unsatisfied performance obligations, where the expected contract duration exceeds one year totaling $296.2 million. Of this amount, $75.9 million is expected to be fulfilled by December 31, 2020, $83.0 million by December 31, 2021, $74.3 million by December 31, 2022, $52.5 million by December 31, 2023 and the remainder thereafter. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year.

The Company provides assurance type warranties primarily for product sales in the Harsco Rail Segments. These warranties are typically not priced or negotiated separately (there is no option to separately purchase the warranty) or the warranty does not provide customers with a service in addition to the assurance that the product complies with agreed-upon specifications. Accordingly, such warranties do not represent separate performance obligations. See Note 1, Summary of Significant Accounting Policies for additional information on warranties.
