Summary of Significant Accounting Policies [Abstract] |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES |
1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
The Company operates in two business segments, Water Transmission and Tubular Products. We have Water Transmission manufacturing facilities in Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw, Texas and Monterrey, Mexico. During the second half of 2012, we permanently closed our facility located in Pleasant Grove, Utah, and have transferred its property and equipment to other manufacturing locations. Tubular Products manufacturing facilities are located in Atchison, Kansas; Houston, Texas; and Bossier City, Louisiana. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances at that time. On an on-going basis, the Company evaluates all of its estimates, including those related to revenue recognition, allowance for doubtful accounts, goodwill, long-lived assets, including depreciation and amortization, inventories, income taxes, and litigation and other contingencies. Actual results could differ from those estimates under different assumptions or conditions. Basis of Consolidation and Presentation The consolidated financial statements include the accounts of Northwest Pipe Company and its subsidiaries over which the Company exercises control as of the financial statement date. Intercompany accounts and transactions have been eliminated. Prior period deferred revenue, which was previously reflected within accrued liabilities, has been reclassified (separated) to its own line item within current assets and net cash provided by (used in) operating activities to conform to current period presentation in the consolidated balance sheets and consolidated statements of cash flows. This reclassification had no impact on cash flows from operations, income from operations, net income, or total liabilities. Lucid Energy LLC (“Lucid Energy”), over which the Company exercises significant influence but does not control, is accounted for under the equity method of accounting. Lucid Energy is a clean energy company based in Portland, Oregon. At December 31, 2012, we have convertible notes receivable from Lucid Energy, however the carrying value of our notes receivable and investment is zero. Northwest Pipe Asia Pte. Ltd. (“NWPA”) was previously accounted for under the equity method of accounting and was sold to the controlling owners of the business for $0.8 million on April 1, 2011. The Company previously exercised significant influence but did not control NWPA. During the year ended December 31, 2011, the Company recorded purchases of property and equipment of $0.2 million, net of eliminations. All proceeds from the sale have been received by the Company and no intercompany balances remained outstanding at December 31, 2011. On June 1, 2011, the Company sold all assets of the traffic systems product line of the Tubular Products facility in Houston, Texas. Assets sold as part of this sale included the (i) raw materials, work-in-process, finished goods and related fuel and supplies inventories, (ii) tangible personal property located at the Houston facilities or used by the Company in connection with the traffic business, including machinery, equipment, tooling, operating and maintenance manuals, parts and all other tangible assets used in or related to the traffic business, (iii) receivables, and (iv) other assets. Total consideration of $13.7 million was received, resulting in a gain of $2.9 million recognized in other expense (income), net during the second quarter of 2011. The calculation of the gain on sale included a write-off of $973,000 of goodwill. Out-of-Period Adjustment In the first quarter of 2012, net sales was increased by $0.8 million for revised estimates used in the computation of revenue recognized on the percentage of completion method that should have been recorded in the year ended December 31, 2011. In the third quarter of 2012, cost of sales was decreased by $0.4 million to correct an overstatement of expenses that had originally been recorded in the year ended December 31, 2011 ($0.1 million), first quarter of 2012 ($0.1 million) and the second quarter of 2012 ($0.2 million). When reviewing these errors in conjunction with other immaterial uncorrected adjustments impacting prior periods, the Company concluded that the adjustments did not, individually or in the aggregate, result in a material misstatement of the Company’s consolidated financial statements for any prior period, and are not material to the Company’s 2012 annual and quarterly financial statements. Cash and Cash Equivalents Cash and cash equivalents consist of cash and short term highly liquid investments with remaining maturities of three months or less when purchased. Escrow Account The escrow account, to be used for qualifying project costs under the financing arrangement for the Bossier City facility, is included in other assets. Funds are released from escrow upon the Company’s payment of qualifying project costs. Restricted cash held in the escrow account totaled $0.9 million and $0.9 million at December 31, 2012 and 2011, respectively. Receivables and Allowance for Doubtful Accounts Trade receivables are reported on the balance sheet net of any doubtful accounts. The Company maintains allowances for estimated losses resulting from the inability of its customers to make required payments or from contract disputes. The amounts of such allowances are based on Company history and management’s judgment. At least monthly, the Company reviews past due balances to identify the reasons for non-payment. The Company will write off a receivable account once the account is deemed uncollectible. The Company believes the reported allowances at December 31, 2012 and 2011 are adequate. If the customers’ financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes were to escalate, additional allowances may need to be recorded which would result in additional expenses being recorded for the period in which such determination was made. Customer Prepayments Contractual terms may require prepayment of a portion of a contract value in advance of completing the work. Advanced deposits are recorded in accrued liabilities and are offset by invoices as work is performed on the contract. Advanced deposits totaled $9.4 million and $2.0 million at December 31, 2012 and 2011, respectively. Inventories Inventories are stated at the lower of cost or market. Raw material inventories of steel are stated at cost, either on a specific identification basis or on an average cost basis. All other raw material inventories, as well as supplies, are stated on an average cost basis. Finished goods are stated at cost using the first-in, first-out method of accounting. Property and Equipment Property and equipment is stated at cost. Maintenance and repairs are expensed as incurred, and costs of new equipment and buildings, as well as costs of expansions or refurbishment of existing equipment and buildings, including interest where applicable, are capitalized. Depreciation and amortization are determined by the units of production method for most equipment and by the straight-line method for the remaining assets based on the estimated useful lives of the related assets. Depreciation expense calculated under the units of production method may be less than, equal to, or greater than depreciation expense calculated under the straight-line method due to variances in production levels. Upon disposal, costs and related accumulated depreciation of the assets are removed from the accounts and resulting gains or losses are reflected in operating expenses. The Company leases certain equipment under long-term capital leases, which are being amortized on a straight-line basis over the shorter of its useful life or the lease term. The Company assesses impairment of property and equipment whenever changes in circumstances indicate that the carrying values of the assets may not be recoverable. The recoverable value of long-lived assets is determined by estimating future undiscounted cash flows using assumptions about the expected future operating performance of the Company. The estimates of undiscounted cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions, or changes to business operations. If the carrying value of the property and equipment is not estimated to be recoverable, an impairment loss is calculated and recorded. Estimated useful lives by major classes of property and equipment are as follows:
Land improvements |  |  | 15 – 30 years |  |  |
Buildings |  |  | 20 – 40 years |  |  |
Machinery and equipment |  |  | 3 – 30 years |  |  |
Goodwill Goodwill related to the Company’s Tubular Products Group, one of the Company’s operating segments and reporting units, of $20.5 million at December 31, 2012 and 2011, represents the excess of purchase price over the assigned value of the net assets in connection with the segment’s acquisitions. The change in the carrying amount of goodwill for the year ended December 31, 2011 was due to the sale of all assets of the traffic systems product line of the Tubular Products facility in Houston, Texas. No accumulated impairment charges are included within the Goodwill balance at December 31, 2012.

Goodwill is reviewed for impairment annually or whenever events occur or circumstances change that would more likely than not reduce the fair value of the Tubular Products Group below its carrying amount. The Company periodically performs a quantitative analysis, even when the qualitative analysis indicates that fair value of goodwill is above its carrying amount. The Company conducts its annual impairment testing as of December 31. In accordance with our critical accounting policy, fair value of the Tubular Products Group’s goodwill was evaluated under a qualitative approach which took into account industry and market conditions, cost factors, overall financial performance, and other relevant entity specific events and changes. A quantitative analysis was performed for 2012 given the financial performance of the Tubular Products Group, specifically the declining margins. Fair value was quantitatively determined with consideration of the income and market approaches as applicable. The income approach is based upon projected future after-tax cash flows (less capital expenditures) discounted to present value using factors that consider the timing and risk associated with the future after-tax cash flows. The key assumptions in the discounted cash flow analysis are the long-term growth rate, the discount rate, and the annual free cash flow. The market approach is based upon historical measures using EBITDA. The Company utilizes a weighted average of the income and market approaches, with a heavier weighting on the income approach because of the relatively limited number of comparable entities for which relevant multiples are available. The Company also utilizes a sensitivity analysis to determine the impact of changes in discount rates and cash flow forecasts on the valuation of the Tubular operating segment. The analysis performed concluded that Goodwill is not impaired at December 31, 2012. If the Company’s assumptions about goodwill change as a result of events or circumstances, and management believes the assets may have declined in value, then impairment charges will be recorded, resulting in lower profits. The operations of the Tubular Products Group are cyclical and its sales and profitability may fluctuate from year to year. In the evaluation of the Company’s operating segment, the Company looks at the long-term prospects for the reporting unit and recognizes that current performance may not be the best indicator of future prospects or value, which requires management judgment. Workers Compensation Insurance The Company is self-insured, or maintains high deductible policies, for losses and liabilities associated with workers compensation claims. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. Pension Benefits The Company has two defined benefit pension plans that have been frozen since 2001. The Company funds these plans to cover current plan costs plus amortization of the unfunded plan liabilities. To record these obligations, management uses estimates relating to investment returns, mortality, and discount rates. Management reviews all of these assumptions on an annual basis. Derivative Instruments The Company conducts business in foreign countries, and, from time to time, settles transactions in foreign currencies. The Company has established a program that utilizes foreign currency forward contracts to offset the risk associated with the effects of certain foreign currency exposures, typically arising from sales contracts denominated in Canadian currency. Foreign currency forward contracts are consistent with the Company’s strategy for financial risk management. The Company utilizes cash flow hedge accounting treatment for qualifying foreign currency forward contracts. Instruments that do not qualify for cash flow hedge accounting treatment are remeasured at fair value at each balance sheet date and resulting gains and losses are recognized in net income (loss). Foreign Currency Transactions Assets and liabilities subject to foreign currency fluctuations are translated into United States dollars at the period-end exchange rate, and revenue and expenses are translated at exchange rates representing an average for the period. Translation adjustments from designated hedges are included in accumulated other comprehensive loss as a separate component of stockholders’ equity. Gains or losses on all other foreign currency transactions are recognized in the statement of operations. The functional currency of the Company’s Mexican operations is the United States dollar. Revenue Recognition Revenue from construction contracts in the Company’s Water Transmission Group is recognized on the percentage-of-completion method. For a majority of contracts, revenue is measured by the costs incurred to date as a percentage of the estimated total costs of each contract (cost-to-cost method). For a small number of contracts, revenue is measured using units of delivery as progress is best estimated by the number of units delivered under the contract. Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation. Selling, general and administrative costs are charged to expense as incurred. The cost of steel is recognized as a project cost when the steel is introduced into the manufacturing process. Estimated total costs of each contract are reviewed on a monthly basis by project management and operations personnel for all active projects. All cost revisions that result in the gross profit as a percent of sales increasing or decreasing by more than two percent are reviewed by senior management personnel. The Company begins recognizing revenue on a project when persuasive evidence of an arrangement exists, recoverability is reasonably assured, and project costs are incurred. Costs may be incurred before the Company has persuasive evidence of an arrangement. In those cases, if recoverability from that arrangement is probable, the project costs are deferred and revenue recognition is delayed. Provisions for losses on uncompleted contracts are made in the period such losses are known. Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions, foreign currency exchange rate movements, changes in raw materials costs, and final contract settlements may result in revisions to estimates of revenue, costs and income and are recognized in the period in which the revisions are determined. Revenue from the Company’s Tubular Products Group is recognized when all four of the following criteria have been satisfied: persuasive evidence of an arrangement exists, the price is fixed or determinable, delivery has occurred, and collectability is reasonably assured. Deferred revenue is recorded when the manufacturing process is complete and customers are invoiced prior to physical delivery of the product. Income Taxes Income taxes are recorded using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. The determination of the provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. The provision for income taxes primarily reflects a combination of income earned and taxed in the various United States federal and state and, to a lesser extent, foreign jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized tax benefits or valuation allowances, and the change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate. The Company records tax reserves for federal, state, local and international exposures relating to periods subject to audit. The development of reserves for these exposures requires judgments about tax issues, potential outcomes and timing, and is a subjective estimate. The Company assesses tax positions and records tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, the largest amount of tax benefit with a greater than 50% likelihood of being realized upon settlement with a tax authority that has full knowledge of all relevant information has been recorded. For those tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Accumulated Other Comprehensive Loss Accumulated other comprehensive loss includes unrealized gains and losses on derivative instruments related to the effective portion of cash flow hedges and changes in the funded status of the defined benefit pension plans, both net of the related income tax effect. Accumulated other comprehensive loss consists of the following:
|  | December 31, |
|  | 2012 |  |  | 2011 |
|  | (in thousands) |
Pension liability adjustment, net of tax benefit of $1,244 and $1,294 |  | $ | (2,188 | ) |  | $ | (2,326 | )
Deferred gain (loss) on cash flow derivatives, net of tax benefit of $50 and expense of $44 |  |  | (85 | ) |  |  | 14 |
Total |  | $ | (2,273 | ) |  | $ | (2,312 | )
Earnings (Loss) per Share Earnings (loss) per basic and diluted weighted average common shares outstanding was calculated as follows for the years ended December 31 (in thousands, except per share data):
|  | 2012 |  |  | 2011 |  |  | 2010 |
Net income (loss) |  | $ | 16,244 |  |  | $ | 12,660 |  |  | $ | (5,440 | )
Basic weighted-average common shares outstanding |  |  | 9,377 |  |  |  | 9,333 |  |  |  | 9,278 |
Effect of potentially dilutive common shares (1) |  |  | 68 |  |  |  | 51 |  |  |  | — |
Diluted weighted-average common shares outstanding |  |  | 9,445 |  |  |  | 9,384 |  |  |  | 9,278 |
Earnings (loss) per common share: |  |  |  |  |  |  |  |  |  |  |  |
Earnings (loss) per basic common share |  | $ | 1.73 |  |  | $ | 1.36 |  |  | $ | (0.59 | )
Earnings (loss) per diluted common share |  |  | 1.72 |  |  |  | 1.35 |  |  |  | (0.59 | )
Antidilutive shares excluded from net earnings per diluted common share calculation |  |  | 92 |  |  |  | 58 |  |  |  | 47 |
(1) | Represents the effect of the assumed exercise of stock options and the vesting of restricted stock units and performance stock awards, based on the treasury stock method.
Concentrations of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of trade receivables, derivative contracts, the escrow account and deferred compensation plan assets. Trade receivables generally represent a large number of customers, including municipalities, manufacturers, distributors and contractors, dispersed across a wide geographic base. At December 31, 2012, no customer had a balance in excess of 10% of total accounts receivable. At December 31, 2011, one customer had a balance which equaled 13% of total accounts receivable. Derivative contracts are with a financial institution rated A-1 by S&P. The escrow account, which is included in other assets, is held in a money market mutual fund. The Company’s deferred compensation plan assets, also included in other assets, are invested in a diversified portfolio of stock and bond mutual funds. Share-based Compensation The Company recognizes the compensation cost of employee and director services received in exchange for awards of equity instruments based on the grant date estimated fair value of the awards. Share-based compensation cost is recognized over the period during which the employee or director is required to provide service in exchange for the award, and as forfeitures occur, the associated compensation cost recognized to date is reversed. Share-based compensation cost related to awards with a performance-based condition is recognized based on the probable outcome of the performance conditions, which requires judgment. The Company estimates the fair value of stock options using the Black-Scholes-Merton option pricing model. The Black-Scholes-Merton option pricing model requires the Company to estimate key assumptions such as expected term, volatility, risk-free interest rates and dividend yield to determine the fair value of stock options, based on both historical information and management judgment regarding market factors and trends. The Company estimates the fair value of Restricted Stock Units (“RSUs”) and Performance Stock Awards (“PSAs”) using the value of the Company’s stock on the date of grant, with the exception of market-based PSAs, for which a Monte Carlo simulation model is used. The Monte Carlo simulation model calculates many potential outcomes for an award and estimates fair value based on the most likely outcome, See Note 11, “Share-based Compensation Plans” for further discussion of the Company’s share-based compensation. Recent Accounting and Reporting Developments Accounting Changes In May 2011, the FASB issued ASU 2011-04, which amends the wording used to describe the requirements for measuring fair value and expands fair value disclosure requirements. This guidance is effective for interim and annual periods beginning after December 15, 2011. The Company adopted this guidance on January 1, 2012 as required. As this guidance only amends disclosure requirements, the adoption did not impact the Company’s consolidated financial position, results of operations or cash flows. In June 2011, the FASB issued ASU 2011-05, which eliminates the option to present components of other comprehensive income as part of the Statement of Stockholders’ Equity. All changes in components of comprehensive income must be presented in (1) a single continuous statement of comprehensive income, which presents the total of comprehensive income, the components of net income, and the components of comprehensive income, or (2) two separate but consecutive statements. Under either presentation method, reclassification adjustments between other comprehensive income and net income are required to be presented on the face of the financial statements. In October 2011, the FASB decided to delay the effective date of the requirement to present reclassifications of other comprehensive income on the face of the income statement. All other guidance in ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. The Company adopted the effective portions of this guidance on January 1, 2012 as required. The adoption of this guidance did not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income and thus had an impact on the presentation of comprehensive income in the consolidated financial statements only. Recent Accounting Standards In December, 2011, the FASB issued ASU 2011-11 which requires companies to disclose information regarding offsetting and other arrangements for derivatives and other financial instruments. In January 2013, the FASB issued ASU 2013-01, which limited the scope of the balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. This guidance is effective for interim and annual periods beginning on or after January 1, 2013. The adoption of this guidance is not expected to have a significant impact on the Company’s consolidated financial position as the new requirements are primarily disclosure related. In February 2013, the FASB issued ASU 2013-02, which clarified the reclassification requirements of ASU 2011-05 which were previously delayed by the FASB in October 2011. Reclassification adjustments which are not reclassified from other comprehensive income to net income in their entirety may instead be parenthetically cross referenced to the related footnote on the face of the financial statements for additional information. This guidance is effective for interim and annual reporting periods beginning after December 15, 2012 and will have an impact on the presentation of comprehensive income in the consolidated financial statements only.
