Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. As permitted by these instructions, they do not include all of the information and notes required by generally accepted accounting principles (GAAP) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. All intercompany balances and transactions have been eliminated in consolidation. The results of operations for the three and six months ended March 31, 2020, are not necessarily indicative of the results that may be expected for the full fiscal year. The balance sheet at September 30, 2019, has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements.
Estimates | Estimates The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities and the reported amounts of revenue and expenses. At each reporting period end, we make estimates including those related to revenue recognition and cost estimation on certain contracts, the realizability of goodwill and amounts related to income taxes, certain accrued liabilities and contingencies and litigation. We base our estimates on historical experience and expectations of the future that we believe to be reasonable.
Leases | Leases Effective October 1, 2019, we adopted ASU No. 2016-02, Leases (Topic 842). The new standard requires that assets and liabilities arising under leases be recognized on the balance sheet, except for those with an initial term of less than 12 months. We adopted this standard using a modified retrospective approach. Accordingly, we did not recast prior period financial information. Certain elections were made in adopting the standard. •We elected to use the package of practical expedients which, among other things, allows us to not reassess historical lease classification. •We do not separate lease and non-lease components for all classes of leases, which allows us to account for a lease as a single component. •We used the optional transition method, which did not require us to recast our comparative periods. •We did not use the hindsight practical expedients, which would have allowed us to use hindsight in determining the reasonably certain lease term. •We did not adjust our accounting for leases with an initial term of twelve months or less.
Changes in financial reporting | Changes in financial reporting Leases Effective October 1, 2019, we adopted ASU No. 2016-02, Leases (Topic 842). The new standard requires that assets and liabilities arising under leases be recognized on the balance sheet, except for those with an initial term of less than 12 months. We adopted this standard using a modified retrospective approach. Accordingly, we did not recast prior period financial information. Certain elections were made in adopting the standard. •We elected to use the package of practical expedients which, among other things, allows us to not reassess historical lease classification. •We do not separate lease and non-lease components for all classes of leases, which allows us to account for a lease as a single component. •We used the optional transition method, which did not require us to recast our comparative periods. •We did not use the hindsight practical expedients, which would have allowed us to use hindsight in determining the reasonably certain lease term. •We did not adjust our accounting for leases with an initial term of twelve months or less. Upon adopting Topic 842, we recognized a lease liability of $214.5 million, reflecting the present value of the future remaining minimum lease payments. Changes to our opening balance sheet are summarized below. There was no cumulative impact to our retained earnings and the changes did not cause any material changes in our statements of operations or our statements of cash flows. The adoption of Topic 842 does not affect our compliance with our existing contracts, including our credit facility.

At the adoption of Topic 842, the Company recognized deferred tax assets and liabilities corresponding to the operating lease liabilities and operating right-of-use assets, respectively. These balances offset each other and no net effect resulted from this change. Additional information and disclosures relating to this change are included within "Note 3. Leases." Forthcoming changes In August 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This accounting guidance requires customers in cloud-computing arrangements to identify and defer certain implementation costs in a manner broadly consistent with that of existing guidance on the costs to develop or obtain internal-use software. We will adopt this guidance on October 1, 2020. We may adopt this guidance using either a prospective or retrospective methodology. We are currently assessing the future impact of this update on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This update introduces a new model for recognizing credit losses on financial instruments, including losses on accounts receivable. We will adopt this guidance on October 1, 2020 and any changes will be recorded as a cumulative adjustment to retained earnings. We are currently assessing the future impact of this update on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. This standard will not change the manner in which we would identify a goodwill impairment but would change any subsequent calculation of an impairment charge. We will adopt this guidance on October 1, 2020. The effect of this new standard will depend upon the outcome of future goodwill impairment tests. Other recent accounting pronouncements are not expected to have a material effect on our financial statements
