SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended
--- | ---
Aug. 31, 2018
Accounting Policies [Abstract] |
Consolidation | Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned and majority owned subsidiaries and certain variable interest entities ("VIEs") for which the Company is the primary beneficiary. Intercompany account balances and transactions have been eliminated. Upon inception of an arrangement with a potential VIE, the Company performs an assessment of the contractual agreements that define the ownership structure, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties when determining whether it is the primary beneficiary of the entity. The Company concludes that it is the primary beneficiary and consolidates the VIE if it has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that potentially could be significant to the VIE. The Company's assessment of whether it is the primary beneficiary of the VIE is continuously performed.
Use of Estimates | Use of Estimates The preparation of the Company's consolidated financial statements in accordance with accounting principles generally accepted in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of net sales and expenses during the reporting period. Significant items subject to such estimates and assumptions include the valuation of assets received in acquisitions; the carrying value of inventory and long-lived assets, including goodwill; valuation allowances for receivables and deferred income taxes; percentage of completion accounting method for revenue recognition; share-based compensation; potential litigation claims and settlements; environmental liabilities; and the carrying value of assets held for sale. Actual results could differ significantly from these estimates and assumptions.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash on deposit and short-term, highly-liquid investments with original maturities of three months or less at the date of purchase.
Revenue Recognition | Revenue Recognition and Allowance for Doubtful Accounts The Company recognizes sales when title passes to the customer either when goods are shipped or when they are delivered based upon the terms of the sale, there is persuasive evidence of an arrangement, the price is fixed or determinable and collectability is reasonably assured. When the Company estimates that a firm purchase commitment from a customer will result in a loss, the Company accrues the entire loss as soon as it is probable and estimable. The Company accounts for certain fabrication projects based on the percentage of completion accounting method, based primarily on contract cost incurred to date compared to total estimated contract cost. Changes to total estimated contract cost, or loss, if any, are recognized in the period in which they are determined. Sales recognized in excess of amounts billed of $49.2 million and $23.1 million are classified as current assets and are reflected in accounts receivable on the Company's consolidated balance sheets as of August 31, 2018 and 2017, respectively. Accounts receivable included retainage of $41.8 million and $43.2 million as of August 31, 2018 and 2017, respectively. Shipping and other transportation costs billed to customers are included in net sales and the related costs incurred are reflected in cost of goods sold in the Company's consolidated statements of earnings.
Allowance for Doubtful Accounts | llowance for doubtful accounts to reflect its estimate of the uncollectability of accounts receivable. These reserves are based on historical trends, current market conditions and customers' financial condition. The Company reviews and sets credit limits for each customer. Some of the Company's divisions use credit insurance to ensure payment in accordance with the terms of sale. Generally, collateral is not required. Approximately 18% and 28% of total receivables at August 31, 2018 and 2017, respectively, were secured by credit insurance.
Inventories | Inventories At August 31, 2018, inventories were stated at the lower of cost or net realizable value and were determined by the weighted average cost method. Elements of cost in finished goods inventory in addition to the cost of material include depreciation, amortization, utilities, consumable production supplies, maintenance, production, wages and transportation costs. Additionally, the costs of departments that support production, including materials management and quality control, are allocated to inventory.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are recorded at cost. Maintenance is expensed as incurred. Leasehold improvements are amortized over the shorter of their estimated useful lives or the lease term. Depreciation and amortization is recorded on a straight-line basis over the following estimated useful lives:
Buildings | 7 | to | 40 | years
Land improvements | 3 | to | 25 | years
Leasehold improvements | 3 | to | 15 | years
Equipment | 3 | to | 25 | years
The Company evaluates impairment of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For each asset or group of assets held for use with indicators of impairment, the Company compares the sum of the expected future cash flows generated by the asset or group of assets with its associated net carrying value. If the net carrying value of the asset or group of assets exceeds expected undiscounted future cash flows, the excess of the net book value over estimated fair value is charged to impairment loss in the accompanying consolidated statements of earnings. Properties held for sale are reported at the lower of their carrying amount or their estimated sales price, less estimated costs to sell.
Government Assistance | Government Assistance Government assistance, including non-monetary grants, herein collectively referred to as grants, are not recognized until there is reasonable assurance that the Company will comply with the conditions of the grant and the Company will receive the grant. Generally, government grants fall into two categories: grants related to assets and grants related to income. Grants related to assets are government grants for the purchase, construction or other acquisition of long-lived assets. The Company accounts for grants related to assets as deferred income with the offset to an asset account, such as fixed assets, on the consolidated balance sheets. Non-monetary grants are recognized at fair value. The Company recognizes the deferred income in profit or loss on a systematic basis over the useful life of the asset; which, consistent with the Company's fixed assets policy, is straight-line. The period over which grants are recognized depends on the terms of the agreement. Grants related to specific expenses already incurred are recognized in profit or loss in the period in which the grant becomes receivable. A grant related to depreciable assets is recognized in profit or loss over the life of the depreciable asset. Grants related to non-depreciable assets may require the fulfillment of certain obligations. In such cases, these grants are recognized in profit or loss over the periods that bear the cost of meeting the obligations. Grants related to income are any grants that are not considered grants related to assets, such as grants to compensate for certain expenses. Grants related to income are recognized as a reduction in the related expense in the period that the recognition criteria are met. See Note 11, New Markets Tax Credit Transactions.
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill is tested for impairment at the reporting unit level annually and whenever events or circumstances indicate that the carrying value may not be recoverable. To evaluate goodwill for impairment, the Company utilizes a quantitative test that compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is indicated in the amount that the carrying value exceeds the fair value of the reporting unit, not to exceed the goodwill value for the reporting unit. The Company's reporting units represent an operating segment or one level below an operating segment. The fair value of each reporting unit is estimated using an income approach based on the present value of expected future cash flows and a market approach based on valuation metrics of comparable peer companies and a reconciliation of the Company's estimate of the aggregate fair value of the reporting units to the Company's market capitalization, including a control premium. The determination of fair value involves a number of significant assumptions and estimates, including discount rates, volumes, prices, capital expenditures and the impact of current market conditions. These estimates could be materially impacted by adverse changes in these assumptions. For fiscal 2018 and 2016, the Company's annual goodwill impairment analysis did not result in any impairment charges at any of the Company's reporting units. For fiscal 2017, the annual goodwill impairment analysis resulted in a goodwill impairment charge of $2.0 million related to a reporting unit in discontinued operations. See Note 7, Goodwill and Other Intangible Assets, for additional details of the impairment charges. As of August 31, 2018 and 2017, one of the Company's reporting units within its Americas Fabrication segment comprised $51.1 million and $51.6 million, respectively, of the Company's total goodwill. Goodwill at the Company's other reporting units was not material at August 31, 2018 and 2017. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment charges are recorded on finite-lived intangible assets when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amounts.
Contingencies | Contingencies The Company accrues for claims and litigation, including environmental investigation and remediation costs, when they are both probable and the amount can be reasonably estimated. Environmental costs are based upon estimates regarding the sites for which the Company will be responsible, the scope and cost of work to be performed at each site, the portion of costs that will be shared with other parties and the timing of remediation. Where timing and amounts cannot be reasonably determined, a range is estimated and the lower end of the range is typically recorded.
Stock-Based Compensation | Stock-Based Compensation The Company recognizes stock-based equity and liability awards at fair value. The fair value of each stock-based equity award is estimated at the grant date using the Black-Scholes or Monte Carlo pricing model. Total compensation cost of the stock-based equity award is amortized over the requisite service period using the accelerated method of amortization for grants with graded vesting or the straight-line method for grants with cliff vesting. Stock-based liability awards are measured at fair value at the end of each reporting period and will fluctuate based on the price of CMC common stock and performance relative to the targets.
Income Taxes | Income Taxes CMC and its U.S. subsidiaries file a consolidated federal income tax return. Deferred income taxes are provided for temporary differences between financial statement and income tax bases of assets and liabilities. The principal differences are described in Note 14, Income Tax. Benefits from income tax credits are reflected currently in earnings. The Company records income tax positions based on a more likely than not threshold that the tax positions will be sustained on examination by the taxing authorities having full knowledge of all relevant information.
Foreign Currencies | Foreign Currencies The functional currency of the Company's Polish operations is the local currency. Translation adjustments are reported as a component of accumulated other comprehensive loss. Transaction gains (losses) from transactions denominated in currencies other than the functional currency related to continuing operations were $1.8 million, $2.0 million and $(15.6) million for the years ended August 31, 2018, 2017 and 2016, respectively, and are primarily included in selling, general and administrative expenses in the Company's consolidated statements of earnings.
Derivative Financial Instruments | Derivative Financial Instruments The Company recognizes derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. Derivatives that are not designated as hedges are adjusted to fair value through net earnings. Changes in the fair value of derivatives that are designated as hedges are recognized depending on the nature of the hedge. In the case of fair value hedges, changes are recognized as an offset against the change in fair value of the hedged balance sheet item. When the derivative is designated as a cash flow hedge and is highly effective, changes are recognized as other comprehensive income. The ineffective portion of a change in fair value for derivatives designated as hedges is recognized in net earnings. When a derivative instrument is sold, terminated, exercised, or expires, the gain or loss is recorded in the consolidated statement of earnings for fair value hedges, and the cumulative unrealized gain or loss, which had been recognized in the statement of comprehensive income, is reclassified to the consolidated statement of earnings for cash flow hedges. Additionally, when hedged items are sold or extinguished, or the anticipated transaction being hedged is no longer expected to occur, the Company recognizes the gain or loss on the designated hedged financial instrument.
Fair Value | Fair Value The Company has established a fair value hierarchy which prioritizes the inputs to the valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement. Level 1 represents unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 represents quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) which are observable, either directly or indirectly. Level 3 represents valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements In the fourth quarter of fiscal year 2018, the Company early adopted Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows (Topic 230), issued by the Financial Accounting Standards Board (“FASB”) requiring that the statement of cash flows explain the change in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The adoption of ASU 2016-18 did not materially impact our consolidated financial statements. In the fourth quarter of fiscal year 2018, the Company early adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), issued by the FASB. The amendments in this guidance allow for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The Company evaluated the impact of the tax revisions to accumulated other comprehensive income and determined that the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require a customer in a hosting arrangement that is a service contract to follow the internal-use software guidance in ASC 250-40 to determine which implementation costs to capitalize or to expense as incurred. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. This ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is evaluating the impact of this ASU on its consolidated financial statements and disclosures. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815). The ASU better aligns accounting rules with a company's risk management activities; better reflects economic results of hedging in financial statements; and simplifies hedge accounting treatment. For public companies, this standard is effective for annual periods beginning after December 15, 2018, including interim periods within those periods. The standard must be applied to hedging relationships existing on the date of adoption and accounted for using a prospective basis. The Company is currently evaluating the impact of this guidance on its consolidated financial statements as well as determining the Company's planned adoption date. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). ASU 2016-15 is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented in the statement of cash flows. The provisions of this guidance require retrospective application to all periods presented. The new standard provides guidance on eight specific cash flow issues, including the statement of cash flows treatment of beneficial interests in securitized financial transactions, which encompasses activities under the Company's sale of accounts receivables programs in the U.S. and Poland. Upon adoption of the standard during the first quarter of fiscal 2019, the Company anticipates the adoption to result in a reduction in the reported amount of cash flows from operating activities with an offsetting increase in cash flows from investing activities in the consolidated statements of cash flows. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), and has modified the standard thereafter. The standard requires a lessee to recognize a right-of-use asset and a lease liability on its balance sheet for all leases with terms of twelve months or longer. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which provides an additional transition method that allows entities to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restating prior periods. This guidance is effective for fiscal years, and interim reporting periods therein, beginning after December 15, 2018 and will be effective for the Company beginning September 1, 2019, at which point the Company plans to adopt the standard. Upon adoption, the Company expects an increase in both right of use assets and right of use liabilities in the consolidated balance sheet. The Company continues to review the effects of ASU 2016-02 and any modifications thereafter, including evaluation of the impact of this guidance on internal processes and systems, internal controls, and its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and has modified the standard thereafter. Under the standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the standard effective September 1, 2018 using the modified retrospective method for transition, applying the guidance to incomplete contracts as of that date. The Company has designed and implemented new accounting policies and additional internal controls to support compliance with the standard, both in the transition period and prospectively. Upon adoption of the standard, for certain contracts within the Americas Fabrication segment in which revenue is currently recognized on a percentage of completion basis using a cost-to-cost measure of progress, the measure of progress will change to an output measure to align with the pattern of transfer of control. While the Company is in the process of final evaluation it expects to recognize an approximately $2.7 million total cumulative effect as a reduction to the opening balance of retained earnings as of September 1, 2018. In addition, the standard includes expanded disclosure requirements, which the Company will disclose in the first quarter of fiscal year 2019.
