Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Consolidated financial statements | The consolidated balance sheet as of March 31, 2021, the consolidated statements of comprehensive income (loss) for the quarters ended March 31, 2021 and 2020, the consolidated statements of shareholders’ equity for the quarters ended March 31, 2021 and 2020 and the consolidated statements of cash flows for the quarters ended March 31, 2021 and 2020 are unaudited. The consolidated balance sheet as of December 31, 2020 was derived from audited consolidated financial statements, but does not include all disclosures required by U.S. generally accepted accounting principles (GAAP). In the opinion of management, all adjustments necessary for a fair statement of the consolidated financial statements are included. Adjustments consist only of normal recurring items, except for any discussed in the notes below. Interim results are not necessarily indicative of results for a full year. The consolidated financial statements and notes are presented in accordance with instructions for Form 10-Q and do not contain certain information included in our annual consolidated financial statements and notes. The consolidated financial statements and notes appearing in this report should be read in conjunction with the consolidated audited financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2020 (the 2020 Form 10-K). The preparation of our consolidated financial statements requires us to make certain estimates and assumptions affecting the amounts reported in the consolidated financial statements and related notes. We base our estimates on historical experience and on various other factors and assumptions that we believe are reasonable under the circumstances, including the estimated impact of extraordinary events, such as the novel coronavirus (COVID-19) pandemic, the results of which form the basis for making judgments about the carrying values of our assets, liabilities, revenues and expenses and the related disclosure of contingent assets and liabilities. Actual results may differ significantly from our estimates and assumptions, including our estimates of the severity and duration of the COVID-19 pandemic. Further information can be found in Note 15. Comparability – During the second quarter of 2020, we identified certain misstatements in our consolidated statement of cash flows for the quarter ended March 31, 2020. Within cash flows from financing activities, proceeds from issuing long-term debt and payments on long-term debt did not properly reflect the borrowing and payment activity that occurred during the quarter. Additionally, we identified a misstatement related to the presentation of unpaid capital expenditures, which impacted the amount reported for the change in accounts payable within cash provided by operating activities and the amount reported for purchases of capital assets within investing activities. We assessed the materiality of these misstatements on prior period financial statements in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 99, Materiality, codified in Accounting Standards Codification (ASC) 250, Presentation of Financial Statements. We concluded that the misstatements were not material to any prior interim period and therefore, amendments of previously filed reports were not required. In accordance with ASC 250, we have corrected the misstatements by revising the consolidated financial statements appearing herein. The revisions had no impact on total assets, total liabilities, shareholders' equity or net income. The impact of the revisions on the consolidated statement of cash flows for the quarter ended March 31, 2020 was as follows:
(in thousands) |  | Previously reported |  | Adjustment |  | Revised
Accounts payable |  | $ | (18,059) |  |  | $ | 7,914 |  |  | $ | (10,145) |
Net cash provided by operating activities |  | 18,554 |  |  | 7,914 |  |  | 26,468 |
Purchases of capital assets |  | (6,355) |  |  | (7,914) |  |  | (14,269) |
Net cash used by investing activities |  | (6,001) |  |  | (7,914) |  |  | (13,915) |
Proceeds from issuing long-term debt |  | 1,011,000 |  |  | (702,000) |  |  | 309,000 |
Payments on long-term debt |  | (754,500) |  |  | 702,000 |  |  | (52,500) |
Net cash provided by financing activities |  | 211,156 |  |  | — |  |  | 211,156 |
Net change in cash, cash equivalents, restricted cash and restricted cash equivalents |  | $ | 210,992 |  |  | $ | — |  |  | $ | 210,992 |
