| Summary of significant accounting policies | Summary of significant accounting policies Organization -AZZ Inc. (the “Company” “AZZ” or “We”) operates primarily in the United States of America and Canada and has recently begun operating in China, Brazil, Poland and the Netherlands. Information about the Company's operations by segment is included in Note 13 to the consolidated financial statements. Basis of consolidation —The consolidated financial statements were prepared in accordance with the accounting principles generally accepted in the United States of America and include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Use of estimates —The preparation of the financial statements in conformity with generally accepted accounting principles in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Concentrations of credit risk —Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. The Company maintains cash and cash equivalents with various financial institutions. These financial institutions are located throughout the United States and Canada, as well as Europe, China and Brazil. The Company's policy is designed to limit exposure to any one institution. The Company performs periodic evaluations of the relative credit standing of those financial institutions that are considered in the Company's banking relationships and has not experienced any losses in such accounts. We believe we are not exposed to any significant credit risk related to cash and cash equivalents. Concentrations of credit risk with respect to trade accounts receivable are limited due to the Company’s diversity by virtue of two operating segments, the number of customers, and the absence of a concentration of trade accounts receivable in a small number of customers. The Company performs continuous evaluations of the collectability of trade accounts receivable and allowance for doubtful accounts based upon historical losses, economic conditions and customer specific events. After all collection efforts are exhausted and an account is deemed uncollectible, it is written off against the allowance for doubtful accounts. Accounts receivable written off, net of recoveries, in fiscal 2016 , 2015 and 2014 were approximately $0.2 million , $0.7 million and $0.3 million , respectively. Collateral is usually not required from customers as a condition of sale. Revenue recognition —The Company recognizes revenue for the Energy Segment upon transfer of title and risk to customer or based upon the percentage of completion method of accounting for electrical products built to customer specifications and services under long-term contracts. We typically recognize revenue for the Galvanizing Segment at completion of the service unless we specifically agree with the customer to hold its material for a predetermined period of time after the completion of the galvanizing process and, in that circumstance, we invoice and recognize revenue upon shipment. Customer advanced payments presented in the balance sheets arise from advanced payments received from our customers prior to shipment of the product and are not related to revenue recognized under the percentage of completion method. The extent of progress for revenue recognized using the percentage of completion method is measured by the ratio of contract costs incurred to date to total estimated contract costs at completion. Contract costs include direct labor and material and certain indirect costs. Selling, general and administrative costs are charged to expense as incurred. Provisions for estimated losses, if any, on uncompleted contracts are made in the period in which such losses are able to be determined. The assumptions made in determining the estimated cost could differ from actual performance resulting in a different outcome for profits or losses than anticipated. Cash and cash equivalents —The Company considers cash and cash equivalents to include cash on hand, deposits with banks and all highly liquid investments with an original maturity of three months or less. Inventories —Cost is determined principally using a weighted-average method for the Energy Segment and the first-in-first-out (FIFO) method for the Galvanizing Segment. Property, plant and equipment —For financial reporting purposes, depreciation is computed using the straight-line method over the estimated useful lives of the related assets as follows: Buildings and structures 10-25 years Machinery and equipment 3-15 years Furniture and fixtures 3-15 years Automotive equipment 3 years Computers and software 3 years Maintenance and repairs are charged to expense as incurred; renewals and betterments that significantly extend the useful life of the asset are capitalized. Long-lived assets, intangible assets and goodwill —Purchased intangible assets included on the balance sheets are comprised of customer lists, backlogs, engineering drawings and non-compete agreements. Such intangible assets are being amortized using the straight-line method over the estimated useful lives of the assets ranging from two to nineteen years. The Company records impairment losses on long-lived assets, including identifiable intangible assets, when events and circumstances indicate that the assets might be impaired and the undiscounted projected cash flows associated with those assets are less than their carrying amount. In those situations, impairment loss on a long-lived asset is measured based on the excess of the carrying amount of the asset over the asset’s fair value. For goodwill, the Company performs an annual impairment test on December 31st each year or as indicators are present. The test is calculated using the anticipated future cash flows after tax from our operating segments, which includes the impact of our corporate related expenses. Based on the present value of the future cash flows, we determine whether impairment may exist. A significant change in projected cash flows or cost of capital for future years could result in an impairment of goodwill in future years. Variables impacting future cash flows include, but are not limited to, the level of customer demand for and response to products and services we offer to the power generation market, the electrical transmission and distribution markets, the general industrial market and the hot dip galvanizing market; changes in economic conditions of these various markets; raw material and natural gas costs and availability of experienced labor and management to implement our growth strategies. As of February 29, 2016, no impairment of long-lived assets, intangible assets or goodwill was determined. Debt issue costs —Debt issue costs, included in other assets, are amortized using the effective interest rate method over the term of the debt. Income taxes —We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. As applicable, we record uncertain tax positions in accordance with GAAP on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. We currently do not have any unrecognized tax benefits to record related to U.S. federal, state or, foreign tax exposure. We continue to review our tax exposure for any significant need to record unrecognized tax benefits in the future. The Company is subject to taxation in the U.S. and various state, provincial and local and foreign jurisdictions. With few exceptions, as of fiscal 2016, the Company is no longer subject to U.S. federal or state examinations by tax authorities for years before fiscal 2013. Share-based compensation —The Company has granted restricted stock units awards, performance share units and stock appreciation rights for a fixed number of shares to employees and directors. A discussion of share-based compensation can be found in Note 11 to the Consolidated Financial Statements. Financial instruments —Fair value is an exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Hierarchy Levels 1, 2, or 3 are terms for the priority of inputs to valuation techniques used to measure fair value. Hierarchy Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Hierarchy Level 2 inputs are inputs other than quoted prices included with Level 1 that are directly or indirectly observable for the asset or liability. Hierarchy Level 3 inputs are inputs that are not observable in the market. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and debt. Our financial instruments are presented at fair value in our consolidated balance sheets, with the exception of our outstanding Senior Notes. For fiscal 2016 and 2015 the fair value of our senior outstanding notes, as described in Note 12 to the Consolidated Financial Statements, was approximately $154.7 million and $164.4 million , respectively. These fair values were determined using the discounted cash flow at the market rate as well as the applicable market interest rates classified as Level 2 inputs. During fiscal 2016 a principal payment was made in the amount of $14.3 million related to the $100.0 million unsecured Senior Notes due March 31, 2018, which accounts for a portion of the decrease in fair value for the compared periods in conjunction with lower market interest rates. Derivative financial instruments —From time to time, the Company uses derivatives to manage interest rate risk. The Company’s policy is to use derivatives for risk management purposes only, which includes maintaining the ratio between the Company’s fixed and floating rate debt obligations that management deems appropriate, and prohibits entering into such contracts for trading purposes. The Company enters into derivatives only with counterparties (primarily financial institutions) which have substantial financial wherewithal to minimize credit risk. As the result of the recent global financial crisis, a number of financial institutions have failed or required government assistance, and counterparties considered substantial may develop credit risk. The amount of gains or losses from the use of derivative financial instruments has not been and is not expected to be material to the Company’s consolidated financial statements. As of February 29, 2016 , the Company had no derivative financial instruments. Warranty reserves —Within other accrued liabilities, a reserve has been established to provide for the estimated future cost of warranties on a portion of the Company’s delivered products. Management periodically reviews the reserves, and adjustments are made accordingly. A provision for warranty on products is made on the basis of the Company’s historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The following is a roll-forward of amounts accrued for warranties (in thousands): Balance at February 28, 2013 $ 2,073 Warranty costs incurred (2,246 ) Additions charged to income 1,511 Balance at February 28, 2014 $ 1,338 Warranty costs incurred (1,294 ) Additions charged to income 2,243 Balance at February 28, 2015 $ 2,287 Warranty costs incurred (2,570 ) Additions charged to income 3,198 Balance at February 29, 2016 $ 2,915 Accumulated Other Comprehensive Income (Loss) —On January 21, 2011, we entered into a Note Purchase Agreement, (the “2011 Agreement”) and incurred fixed rate, long-term indebtedness of $125.0 million in relation to the 2011 Agreement. See Note 12 to the Consolidated Financial Statements. In anticipation of the issuance of Senior Notes thereunder, we entered into a treasury lock hedging transaction with Bank of America Merrill Lynch (BAML) in order to eliminate the variability of cash flows on the forecasted fixed rate coupon of the debt during the pre-issuance period. The hedging transaction settled during the Company’s third fiscal quarter of fiscal 2011, and the Company received a payment from BAML in the amount of $0.8 million resulting therefrom. The notional value of the hedge was $75.0 million and qualified for hedge accounting as a cash flow hedge. The gain on the settlement was recorded as a component of Accumulated Other Comprehensive Income (Loss) and is being amortized to interest expense in the form of a credit over the life of the 10 year loan. Amortization of this gain to interest expense was recorded in a credit of $0.1 million for fiscal 2016, 2015, and 2014. Accumulated Other Comprehensive Income (Loss) also includes foreign currency translation adjustments from our foreign subsidiaries consisting of Aquilex SRO, AZZ Trading (Shanghai), Blenkhorn and Sawle, Galvan, Galvcast and G3. Foreign Currency Translation —The local currency is the functional currency for the Company’s foreign operations. Related assets and liabilities are translated into United States dollars at exchange rates existing at the balance sheet date, and revenues and expenses are translated at weighted-average exchange rates. The foreign currency translation adjustment is recorded as a separate component of shareholders’ equity and is included in accumulated other comprehensive income (loss). Accruals for Contingent Liabilities — The amounts we record for estimated claims, such as self-insurance programs, warranty, environmental and other contingent liabilities, requires us to make judgments regarding the amount of expenses that will ultimately be incurred. We use past history and experience and other specific circumstances surrounding these claims in evaluating the amount of liability that should be recorded. Actual results may be different than what we estimate. In connection with our acquisition of NLI on June 1, 2012, we may be obligated to make an additional payment of up to $20.0 million which will be based on the future financial performance of the NLI business. Based on the cumulative performance to date and current forecast, we do not believe this additional payment will be probable and based on that determination, the accrual recorded at the end of fiscal 2014 of $9.1 million was reversed during fiscal 2015. New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases." The standard requires a lessee to recognize a liability to make lease payments and a right-of-use asset representing a right to use the underlying asset for the lease term on the balance sheet. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact that this standard will have on our consolidated financial statements. In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently, debt issuance costs are recognized as deferred charges and recorded as other assets. The guidance is effective for annual and interim periods beginning after December 15, 2015 with early adoption permitted and is to be implemented retrospectively. Adoption of the new guidance will only affect the presentation of the Company's consolidated balance sheets and will have no impact to our operating results. The Company will implement the guidance beginning in fiscal 2017. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers", issued as a new Topic, Accounting Standards Codification (ASC) Topic 606 ("ASU 2014-09"). The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The premise of the guidance is that a Company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption. On April 1, 2015, the FASB decided to defer the effective date of the new revenue standard by one year. As a result, public entities would apply the new revenue standard to annual reporting periods beginning after December 15, 2017. This standard will be effective for the Company beginning in fiscal 2019. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its financial statements or decided upon the method of adoption. |
