the consolidated balance sheet and the statement of cash flows must be disclosed when the consolidated balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. The guidance also requires that changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents should not be presented as cash flow activities in the statement of cash flows. An entity with a material balance of amounts generally described as restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. We adopted ASU 2016-18 at the beginning of the first quarter of 2018. Restricted cash amounts have been combined with the cash and cash equivalent balances in the Condensed Consolidated Statement of Cash Flows for each period presented. Adoption of ASU 2016-18 did not have a material impact on our consolidated financial statements.
In August 2017, FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). The new standard simplifies and expands the eligible hedging strategies for financial and nonfinancial risks. It also enhances the transparency of how hedging results are presented and disclosed. Further, the new standard provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings. Adoption of ASU 2017-12 is required for fiscal reporting periods beginning after December 15, 2018, including interim reporting periods within those fiscal years with early adoption being permitted. We do not expect the adoption of ASU 2017-12 to have a material impact on our consolidated financial statements.
In February 2018, FASB issued Accounting Standards Update No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02). The new standard amends ASC 220 to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the “Tax Cuts and Jobs Act” and requires entities to provide certain disclosures regarding stranded tax effects. Adoption of ASU 2018-02 is required for fiscal reporting periods beginning after December 15, 2018, including interim reporting periods within those fiscal years with early adoption being permitted. We do not expect the adoption of ASU 2018-02 to have a material impact on our consolidated financial statements.
In August 2018, FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). The new standard makes various modifications to the disclosure requirements on fair value measurement in Topic 820. Adoption of ASU 2018-13 is required for fiscal reporting periods beginning after December 15, 2019, including interim reporting periods within those fiscal years with early adoption being permitted. We do not expect the adoption of ASU 2018-13 to have a material impact on our consolidated financial statements.
Liquidity and Capital Resources
We generate cash from operations predominantly from the sale of supercomputing systems and related services. We typically have a small number of significant contracts that make up the majority of total revenue. We have also entered into a sales-type lease agreement with a customer, under which we will receive quarterly payments over the term of the lease, which expires in September 2020. Material changes in certain of our balance sheet accounts were due to the level and timing of: product deliveries and customer acceptances, contractually determined billings, cash collections of receivables, inventory purchased for future deliveries, and incentive compensation. Working capital requirements, including inventory purchases and normal capital expenditures, are generally funded with cash from operations.
Cash, cash equivalents and restricted cash increased by $43.9 million, from $140.3 million at December 31, 2017 to $184.2 million at September 30, 2018. As of September 30, 2018, we had working capital of $294.2 million compared to $354.3 million as of December 31, 2017.
Cash flow information included the following (in thousands):
Operating Activities. Net cash provided by operating activities was $40.4 million for the first nine months of 2018 compared to net cash used in operating activities of $38.7 million for the first nine months of 2017. Net cash provided by operating activities in the first nine months of 2018 was primarily driven by collections from customers that resulted in a decrease of $84.6 million in accounts and other receivables and a decrease of $38.1 million in inventory due to customer acceptances of systems that were delivered during the first nine months of 2018. These amounts were largely offset by the net loss, adjusted for non-cash expenses,
