Amendment Description	EXPLANATORY NOTE National Presto Industries, Inc. (the "Company") is filing this Amendment No. 1 to its Form 10-K for the year ended December 31, 2018 to revise its conclusions on the effectiveness of the Company's disclosure controls and procedures and internal controls over financial reporting following an inspection by the Public Company Accounting Oversight Board ("PCAOB") of BDO USA LLP's ("BDO") audit of the Company's financial statements for the year ended December 31, 2018, as further explained in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on October 23, 2019. The revised conclusions did not result in any material adjustments to the Company's consolidated financial statements for the year ended December 31, 2018, and accordingly, all other information presented in the Company's Form 10-K for the year ended December 31, 2018 originally filed with the SEC on March 15, 2019 (the "Original Form 10-K"), with the exception of some language in Note A(12) to the Company's Consolidated Financial Statements, remains unchanged. Note A(12) has been revised solely to indicate that the Company's adoption of ASC Topic 606, Revenue from Contracts with Customers, did not result in any material change to the Company's pattern of revenue recognition, and that for the Defense segment, revenue is primarily recognized when the customer has legal title and formally documents that it has accepted the products.. The Company does not intend to file amendments to any of its previously filed quarterly reports on Form 10-Q for the interim periods of 2018. Except as described above and the inclusion of new certifications by management and a new consent of BDO, this Amendment does not amend, update or change the financial statements or any other disclosures in the Original Form 10-K and does not reflect events occurring after the filing of the Original Form 10-K. Accordingly, this Amendment No. 1 should be read in conjunction with the Original 10-K and Company's filings with the SEC subsequent to the date of the Original Form 10-K.

Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:  (1) USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS: In preparation of the Company's Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and related revenues and expenses. Actual results could differ from the estimates used by management.  (2) BASIS OF PRESENTATION: The Consolidated Financial Statements include the accounts of National Presto Industries, Inc. and its subsidiaries, all of which are wholly-owned. All material intercompany accounts and transactions are eliminated. For a further discussion of the Company's business and the segments in which it operates, please refer to Note L .  On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. (“Drylock”) in exchange for $68,448,000 . The proceeds amount differs from the amount originally disclosed because of the customary post-closing adjustments that were finalized during the second quarter of 2017, totaling $1,448,000 . The asset purchase agreement also provided for additional proceeds of $4,000,000 upon the sale of certain delayed assets, consisting of machinery and equipment that were the subject of an involuntary conversion. The sale of the delayed assets was consummated during the second quarter of 2018 and resulted in no gain or loss. As a result of the aforementioned transactions, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation and classified the assets and liabilities of its Absorbent Products business as held for sale. See Note P for further discussion.  (3) RECLASSIFICATIONS: Certain reclassifications have been made to the prior periods' fi nancial statements to conform to the current period’s financial statement presentation. These reclassifications did not affect net earnings or stockholders’ equity as previously reported . (4) FAIR VALUE OF FINANCIAL INSTRUMENTS: The Company utilizes the methods of determining fair value as described in Financial Accounting Standard Board (“FASB”) Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures to value its financial assets and liabilities. ASC 820 utilizes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  The carrying amount for cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximates fair value due to the immediate or short-term maturity of these financial instruments. The fair value of marketable securities are discussed in Note A(5).  (5) CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES:  Cash and Cash Equivalents: The Company considers all highly liquid marketable securities with an original maturity of three months or less to be cash equivalents. Cash equivalents include money market funds. The Company deposits its cash in high quality financial institutions. The balances, at times, may exceed federally insured limits. Money market funds are reported at fair value determined using quoted prices in active markets for identical securities (Level 1, as defined by FASB ASC 820).  The Company's cash management policy provides for its bank disbursement accounts to be reimbursed on a daily basis. Checks issued but not presented to the bank for payment of $ 3,057,000 and $ 3,157,000 at December 31, 2018 and 2017, respectively, are included as reductions of cash and cash equivalents or b oo k overdrafts in accounts payable, as appropriate.  Marketable Securities: The Company has classified all marketable securities as available-for-sale which requires the securities to be reported at fair value, with unrealized gains and losses, net of tax, reported as a separate component of stockholders' equity. Highly liquid, tax-exempt variable rate demand notes with put options exercisable in three months or less are classified as marketable securities.  At December 31, 2018 and 2017, cost for marketable securities was determined using the specific identification method. A summary of the amortized costs and fair values of the Company's marketable securities at December 31 is shown in the following table. All of the Company’s marketable securities are classified as Level 2, as defined by FASB ASC 820, with fair values determined using significant other observable inputs, which include quoted prices in markets that are not active, quoted prices of similar securities, recently executed transactions, broker quotations, and other inputs that are observable.      (In thousands)  MARKETABLE SECURITIES   Amortized Cost Fair Value Gross Unrealized Gains Gross Unrealized Losses  December 31, 2018  Tax-exempt Municipal Bonds $ 40,156 $ 40,182 $ 44 $ 18  Variable Rate Demand Notes 94,416 94,416 - -  Total Marketable Securities $ 134,572 $ 134,598 $ 44 $ 18   December 31, 2017  Tax-exempt Municipal Bonds $ 30,103 $ 29,994 $ - $ 109  Variable Rate Demand Notes 114,258 114,258 - -  Total Marketable Securities $ 144,361 $ 144,252 $ - $ 109  Proceeds from sales and maturities of marketable securities totaled $ 173,060,000 in 2018, $ 132,752,000 in 2017, and $ 33,863,000 in 2016. There were no realized gross gains or losses related to sales of marketable securities during the years ended December 31, 2018, 2017 and 2016. Net unrealized gains (losses) included in other comprehensive income were $ 135,000 , $ (37,000) and $ (57,000) before taxes for the years ended December 31, 2018, 2017, and 2016, respectively. No unrealized gains or losses were reclassified out of accumulated other comprehensive income during the same periods.  The contractual maturities of the marketable securities held at December 31, 2018 are as follows: $ 21,787,000 within one year; $ 35,857,000 beyond one year to five years; $ 17,538,000 beyond five years to ten years, and $ 59,416,000 beyond ten years. All of the instruments in the beyond five year ranges are variable rate demand notes which, as noted above, can be tendered for cash at par plus interest within seven days . Despite the stated contractual maturity date, to the extent a tender is not honored, the notes become immediately due and payable.  (6) ACCOUNTS RECEIVABLE: The Company's accounts receivable is related to sales of products. Credit is extended based on prior experience with the customer and evaluation of customers' financial condition. Accounts receivable are primarily due within 25 to 60 days. The Company does not accrue interest on past due accounts receivable. Receivables are written off only after all collection attempts have failed and are based on individual credit evaluation and the specific circumstances of the customer. The allowance for doubtful accounts represents an estimate of amounts considered uncollectible and is determined based on the Company's historical collection experience, adverse situations that may affect the customer's ability to pay, and prevailing economic conditions.  (7) INVENTORIES: Housewares/Small Appliance segment inventories are stated at the lower of cost or net realizable value with cost being determined principally on the last-in, first-out (LIFO) method. Defense segment inventories are stated at the lower of cost and net realizable value determined principally on the first-in, first-out (FIFO) method. Inventoried costs relating to contracts in progress are stated at actual production costs, including factory overhead, initial tooling, and other related costs incurred to date, reduced by amounts associated with recognized sales, utilizing a standard costing type method. The Company evaluates inventories to determine if there are any excess or obsolete inventories on hand.  (8) PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment are stated at cost. Straight-line depreciation is provided in amounts sufficient to charge the costs of depreciable assets to operations over their service lives which are estimated at 15 to 40 years for buildings, 3 to 10 years for machinery and equipment, and 15 to 20 years for land improvements. The Company reviews long-lived assets consisting principally of property, plant, and equipment, for impairment when material events and changes in circumstances indicate the carrying value may not be recoverable. As a result of the divestiture of one of its operating facilities in the Defense segment during 2018, the Company recorded an impairment of $2,975,000 during the third quarter of 2018. See Note Q for further explanation. Approximately $264,000 of construction in progress in the Company’s Housewares/Small Appliance segment is presented on the Consolidated Balance Sheet as Machinery and Equipment at December 31, 2018, and approximately $1,437,000 of construction in progress in the Company’s Defense segment is presented on the Consolidated Balance Sheet as Buildings at December 31, 2018. The construction in progress is expected to be completed by the third quarter of 2019. Approximately $374,000 and $764,000 of construction in progress in the Company’s Defense segment is presented on the Consolidated Balance Sheet as Buildings and Machinery and Equipment, respectively, at December 31, 2017.  (9) GOODWILL: The Company recognizes the excess cost of acquired entities over the net amount assigned to the fair value of assets acquired and liabilities assumed as goodwill. Goodwill is tested for impairment on an annual basis at the start of the fourth quarter and between annual tests whenever an impairment is indicated, such as the occurrence of an event that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Impairment losses are recognized whenever the implied fair value of goodwill is less than its carrying value. No goodwill impairments were recognized during 2018, 2017, or 2016.  The Company's goodwill as of December 31, 2018 and 201 7 was $ 11,485,000 , rel ating entirely to its Defense segment, which had no cumulative impairment charges at December 31, 2018.  (10) INTANGIBLE ASSETS: Intangible assets primarily consist of the value of an acquired government sales contract and the value of trademarks and trade secrets. The intangible assets are all attributable to the Defense segment. The government sales contract intangible asset is amortized based on units fulfilled under the applicable contract, while the other intangible assets are amortized on a straight-line basis that approximates economic use, over periods ranging from 2 to 10 years. As of December 31, 2018, the Company determined that the trade secrets, which were acquired during 2017, had an indefinite life.  Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. As a result of the divestiture of one of its operating facilities in the Defense segment during 2018, the Company recorded an impairment of $46,000 during the third quarter of 2018. See Note Q for further explanation. Th ere were no impairments of intangible assets recognized during 2017 or 2016.  There were no intangible assets subject to amortization at December 31, 2018. The gross carrying amounts of the government sales contract and other intangible assets subject to amortization were $21,690,000 and $211,000 , respectively, totaling $21,901,000 at December 31, 2017. Accumulated amortization was $ 0 and $ 19,570,000 at December 31, 2018 and 2017, respectively. Amortization expense was $ 2,167,000 , $ 2,630,000 , and $ 721,000 during the years ended December 31, 2018, 2017, and 2016, respectively.  (11) OTHER ASSETS: Other assets includes prepayments that are made from time to time by the Company for certain materials used in the manufacturing process in the Housewares/Small Appliance segment. The Company expects to utilize the prepayments and related materials over an estimated period of up to two years. As of December 31, 2018 and 2017, $6,864,000 and $11,567,000 of such prepayments, respectively, remained unused and outstanding. At December 31, 2018 and 2017, $5,190,000 and $5,930,000 of these amounts, respectively, are included in Other Current Assets, representing the Company’s best estimate of the expected utilization of the prepayments and related materials during the twelve-month periods following those dates .  (12) REVENUES: The Company’s revenues are derived from short-term contracts and programs that are typically completed within 3 to 24 months and are recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers . The standard was adopted on January 1, 2018 and did not result in any material change to the Company’s pattern of revenue recognition. The Company’s contracts each contain one or more performance obligations: the physical delivery of distinct ordered product or products. The Company provides an assurance type product warranty on its products to the original owner. In addition, for the Housewares/Small Appliances segment, the Company estimates returns of seasonal products and returns of newly introduced products sold with a return privilege. Stand-alone selling prices are set forth in each contract and are used to allocate revenue to the corresponding performance obligations. For the Housewares/Small Appliances segment, contracts include variable consideration, as the prices are subject to customer allowances, which principally consist of allowances for cooperative advertising, defective product, and trade discounts. Customer allowances are generally allocated to the performance obligations based on budgeted rates agreed upon with customers, as well as historical experience, and yield the Company’s best estimate of the expected value for the variable consideration.  The Company's contracts in the Defense segment are primarily with the U.S. Department of Defense (DOD) and DOD prime contractors. As a consequence, this segment's business essentially depends on the product needs and governmental funding of the DOD. Substantially all of the work performed by the Defense segment directly or indirectly for the DOD is performed on a fixed-price basis. Under fixed-price contracts, the price paid to the contractor is awarded based on competition at the outset of the contract and therefore, with the exception of limited escalation provisions on specific materials, is generally not subject to any adjustments reflecting the actual costs incurred by the contractor.  For the Housewares/Small Appliance segment, revenue is generally recognized as the completed, ordered product is shipped to the customer from the Company’s warehouses. For the relatively few situations in which revenue should be recognized when product is received by the customer, the Company adjusts revenue accordingly. For the Defense segment, revenue is primarily recognized when the customer has legal title and formally documents that it has accepted the products. In some situations, the customer may obtain legal title and accept the products at the Company’s facilities, arranging for transportation at a later date, typically in one to four weeks. The Company does not consider the short-term storage of the customer owned products to be a material performance obligation, and no part of the transaction price is allocated to it.  The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, and customer advances and deposits (contract liabilities) on the Company’s Condensed Consolidated Balance Sheets. For the Defense segment, the Company occasionally receives advances or deposits from certain customers before revenue is recognized, resulting in contract liabilities. These advances or deposits do not represent a significant financing component. As of December 31, 2018 and 2017, $9,579,000 and $8,364,000 , respectively, of contract liabilities were included in Accounts Payable on the Company’s Condensed Consolidated Balance Sheets. The Company recognized revenue of $676,000 during 2018 that was included in the Defense segment contract liability at the beginning of the year. The Company monitors its estimates of variable consideration, which includes customer allowances for cooperative advertising, defective product, and trade discounts, and returns of seasonal and newly introduced product, all of which pertain to the Housewares/Small Appliances segment, and periodically makes cumulative adjustments to the carrying amounts of these contract liabilities as appropriate. During 2018 and 2017, there were no material adjustments to the aforementioned estimates. There were no material amounts of revenue recognized during the same periods related to performance obligations satisfied in a previous period. The portion of contract transaction prices allocated to unsatisfied performance obligations, also known as the contract backlog, in the Company’s Defense segment were $333,592,000 and $308,173,000 as of December 31, 2018 and 2017, respectively. The Company anticipates that the unsatisfied performance obligations will be fulfilled in an 18 to 24 -month period. The performance obligations in the Housewares/Small Appliances segment have original expected durations of less than one year.  The Company’s principal sources of revenue are derived from two segments: Housewares/Small Appliance and Defense, as shown in Note L . Management utilizes the performance measures by segment to evaluate the financial performance of and make operating decisions for the Company.  (13) ADVERTISING: The Company's policy is to expense advertising as incurred and include it in selling and general expenses. Advertising expense was $ 181,000 , $ 174,000 , and $ 369,000 in 2018, 2017, and 2016, respectively.  (14) PRODUCT WARRANTY: The Company’s Housewares/Small Appliance segment’s products are generally warranted to the original owner to be free from defects in material and workmanship for a period of 1 to 12 years from date of purchase. The Company allows a 60 -day over-the-counter initial return privilege through cooperating dealers. The Company services its products through a corporate service repair operation. The Company estimates its product warranty liability based on historical percentages which have remained relatively consistent over the years.  The product warranty liability is included in accounts payable on the balance sheet. The following table shows the changes in product warranty liability for the period:      (In thousands)  Year Ended December 31  2018 2017  Beginning balance January 1 $ 383 $ 543  Accruals during the period 315 268  Charges / payments made under the warranties (477) (428)  Balance December 31 $ 221 $ 383  (15) STOCK-BASED COMPENSATION: The Company accounts for stock-based compensation in accordance with ASC 718, Compensation — Stock Compensation . Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense ratably over the requisite service period, net of estimated forfeitures. As more fully described in Note F , the Company awards non-vested restricted stock to employees and executive officers.  (16) INCOME TAXES: Deferred income tax assets and liabilities are recognized for the differences between the financial and income tax reporting bases of assets and liabilities based on enacted tax rates and laws. The deferred income tax provision or benefit generally reflects the net change in deferred income tax assets and liabilities during the year. The current income tax provision reflects the tax consequences of revenues and expenses currently taxable or deductible on various income tax returns for the year reported. Income tax contingencies are accounted for in accordance with FASB ASC 740, Income Taxes . See Note H for summaries of the provision, the effective tax rates, and the tax effects of the cumulative temporary differences resulting in deferred tax assets and liabilities. In December 2017, the United States enacted changes to its tax laws, which included a reduction of the corporate income tax rate from 35% to 21% , beginning in 2018. The reduction in the tax rate resulted in a revaluation of the Company’s deferred tax assets and liabilities held at December 31, 2017.  (17) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS: In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.  In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 provides guidance for estimating credit losses on certain types of financial instruments, including trade receivables, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance requires a modified retrospective transition method and early adoption is permitted. The Company does not expect the adoption of ASU 2016-13 to have a material impact on its consolidated financial statements.  In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company intends to adopt the new standard utilizing a modified retrospective method with no restatement of comparative periods, and also intends to elect the package of practical expedients, as well as the hindsight and short term lease practical expedients. The Company continues to evaluate the impact of the adoption of ASU 2016-02 on its consolidated financial statements. The evaluation includes identifying, cataloging, and categorizing its current leasing arrangements and evaluating new disclosure requirements. The Company estimates the adoption of the new standard will result in the recognition of ROU assets of approximately $4,000,000 , with corresponding lease liabilities of the same amount.  Other pronouncements issued but not effective until after December 31, 2018, are not expected to have a material impact on the Company's consolidated financial statements.

Inventories	B. INVENTORIES: The amount of inventories valued on the LIFO basis was $ 27,788,000 and $ 26,019,000 as of December 31, 2018 and 2017, respectively, and consists of housewares/small appliance finished goods. Under LIFO, inventories are valued at approximately $ 4,024,000 and $ 3,835,000 below current cost determined on a first-in, first-out (FIFO) basis at December 31, 2018 and 2017, respectively. During the years ended December 31, 2018, 2017, and 2016, $ 26,000 , $ 64,000 , and $ 2,451,000 , respectively, of a LIFO layer was liquidated. The Company uses the LIFO method of inventory accounting to improve the matching of costs and revenues for the Housewares/Small Appliance segment.  The following table describes that which would have occurred if LIFO inventories had been valued at current cost determined on a FIFO basis:     Increase (Decrease) – (In thousands, except per share data)  Year Cost of Sales Net Earnings Earnings Per Share  2018 $ (189) $ 143 $ 0.02  2017 $ (1,250) $ 830 $ 0.12  2016 $ 443 $ (292) $ (0.04)  This information is provided for comparison with companies using the FIFO basis.  Inventory for Defense and raw materials of the Housewares/Small Appliance segments are valued under the FIFO method and total $ 66,200,000 and $ 78,420,000 at December 31, 2018 and 2017, respectively. At December 31, 2018, the FIFO total was comprised of $ 1,003,000 of finished goods, $ 59,580,000 of work in process, and $ 5,617,000 of raw material. At December 31, 2017, the FIFO total was comprised of $ 1,223,000 of finished goods, $ 72,219,000 of work in process, and $ 4,978,000 of raw material.

Accrued Liabilities	C. ACCRUED LIABILITIES: At December 31, 2018, accrued liabilities consisted of payroll $ 5,130,000 , product liability $ 4,949,000 , environmental $ 1,120,000 , and other $ 812,000 . At December 31, 2017, accrued liabilities consisted of payroll $5,827,000 , product liability $ 4,965,000 , environmental $ 1,150,000 , and other $ 1,150,000 .  The Company is self-insured for health care costs, although it does carry stop loss and other insurance to cover health care claims once they reach a specified threshold. The Company is also subject to product liability claims in the normal course of business. It is partly self-insured for product liability claims, and therefore records an accrual for known claims and estimated incurred but unreported claims in the Company’s Consolidated Financial Statements. The Company utilizes historical trends and other analysis to assist in determining the appropriate accrual. An increase in the number or magnitude of claims could have a material impact on the Company’s financial condition and results of operations. The Company's policy is to accrue for legal fees expected to be incurred in connection with loss contingencies. See Note K for a discussion of environmental remediation liabilities.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	F. STOCK-BASED COMPENSATION: The Company, from time to time, enters into separate non-vested share-based payment arrangements with employees and executive officers under the Incentive Compensation Plan approved by stockholders on May 18, 2010 and the 2017 Incentive Compensation Plan approved by shareholders on May 16, 2017, which authorized 50,000 and 150,000 shares, respectively, to be available for grants. The Compensation Committee of the Company’s Board of Directors approves all stock-based compensation awards for employees and executive officers of the Company. The Company grants restricted stock that is subject to continued employment and vesting conditions, but has dividend and voting rights, and uses the fair-market value of the Company’s common stock on the grant date to measure the fair value of the awards. The fair value of restricted stock is recognized as expense ratably over the requisite serviced period, net of estimated forfeitures.  During 2018, 2017, and 2016, the Company granted 3,886 shares , 7,837 shares, and 3,162 shares of restricted stock, respectively, to 23 employees and executive officers of the Company. Unless otherwise vested early in accordance with the Incentive Compensation Plans, the restricted stock vests on specified dates in 2021 through 2024 , subject to the recipients’ continued employment or service through each applicable vesting date.  The Company recognized pre-tax compensation expense in the Consolidated Statements of Comprehensive Income related to stock-based compensation of $ 469,000 , $ 545,000 , and $ 391,000 in 2018, 2017, and 2016, respectively. As of December 31, 2018, there was approximately $ 1,406,000 of unrecognized compensation cost related to the restricted stock awards that is expected to be recognized over a weighted-average period of 3. 8 years. There were 1,359 , 6,492 , and 1,284 shares of restricted stock that vested during 2018, 2017, and 2016, respectively.

401(k) Plan	G. 401(K) PLAN: The Company sponsors a 401(k) retirement plan that covers substantially all non-union employees. Historically, the Company matched up to 50 % of the first 4 % of salary contributed by employees to the plan. This matching contribution was made with common stock. Starting in 2004, the Company began to match, in cash, an additional 50 % of the first 4 % of salary contributed by employees plus 3 % of total compensation for certain employees. Contributions made from treasury stock, including the Company's related cash dividends, totaled $ 1,218,000 in 2018, $ 1,194,000 in 2017, and $ 1,225,000 in 2016.

The tax effects of the cumulative temporary differences resulting in deferred tax assets and liabilities are as follows at December 31:     (In thousands)  2018 2017  Deferred tax assets  Insurance (primarily product liability) $ 900 $ 1,023  Vacation 527 596  Inventory 339 654  Deferred compensation 303 253  Environmental 237 275  Doubtful accounts 158 447  Other 37 72  Total deferred tax assets 2,501 3,320   Deferred tax liabilities  Goodwill and other intangibles 1,200 1,112  Depreciation 213 338  Deferred revenue - 875  Total deferred tax liabilities 1,413 2,325   Net deferred tax assets $ 1,088 $ 995  In December 2017, the United States enacted changes to its tax laws, which included a reduction of the corporate income tax rate from 35% to 21% , beginning in 2018. The reduction in the tax rate resulted in a revaluation of the Company’s deferred tax assets and liabilities held at December 31, 2017, causing an increase in its 2017 income tax provision of $534,000 . The Company believes its accounting assessment for the impact of the enacted changes to the United States tax laws is complete.  The Company establishes tax reserves in accordance with FASB ASC 740, Income Taxes . As of December 31, 2018, the carrying amount of the Company’s gross unrecognized tax benefits was $ 320,000 which, if recognized, would affect the Company’s effective income tax rate.  The following is a reconciliation of the Company’s unrecognized tax benefits for the years ended December 31, 2018 and 2017:     (In thousands)  2018 2017  Balance at January 1 $ 459 $ 288  Increases for tax positions taken related to the current year 73 128  Increases for tax positions taken related to prior years - 66  Decreases for tax positions taken related to prior years (54) -  Lapse of statute of limitations (56) (23)  Settlements (102) -  Balance at December 31 $ 320 $ 459  It is the Company’s practice to include tax related interest expense, interest income, and penalties in tax expense. During the years ended December 31, 2018, 2017 and 2016, the Company accrued approximately $14,000 , $ 17,000 and $ 15,000 in interest expense, respectively.  The Company is subject to U.S. federal income tax as well as income taxes of multiple states. During 2018, the state of Wisconsin completed its audits of the tax years 2013 through 2016. During June of 2016, the Internal Revenue Service completed its audits of the tax years 2012 and 2013. As a result of the audits, the tax amortization period of certain intangible assets was shortened. For all states in which it does business, the Company is subject to state audit statutes.

Concentrations [Abstract]
Concentrations	J. CONCENTRATIONS: In the Housewares/Small Appliance segment, one customer accounted for 10 %, 10% , and 11% of consolidated net sales for the years ended December 31, 2018, 2017, and 2016, respectively.  The Company sources most of its housewares/small appliances from vendors in the Orient and, as a result, risks deliveries from the Orient being disrupted by labor or supply problems at the vendors, or transportation delays. Should such problems or delays materialize, products might not be available in sufficient quantities during the prime selling period. The Company has made and will continue to make every reasonable effort to prevent these problems; however, there is no assurance that its efforts will be totally effective. As the majority of the Housewares/Small Appliance segment’s suppliers are located in China, periodic changes in the U.S. dollar and Chinese Renminbi (RMB) exchange rates do have an impact on the segment’s product costs. To date, any material impact from fluctuations in the exchange rate has been to the cost of products secured via purchase orders issued subsequent to the currency value change. Foreign transaction gains/losses are immaterial to the financial statements for all years presented.  The Company's Defense segment manufactures products primarily for the U.S. Department of Defense (DOD) and DOD prime contractors. As a consequence, this segment's future business essentially depends on the product needs and governmental funding of the DOD. During 2018, 2017, and 2016, substantially all of the work performed by this segment directly or indirectly for the DOD was performed on a fixed-price basis. Under fixed-price contracts, the price paid to the contractor is awarded based on competition at the outset of the contract and therefore, with the exception of limited escalation provisions on specific materials, is generally not subject to any adjustments reflecting the actual costs incurred by the contractor. In addition, in the case of the 40mm systems contract, key components and services are provided by third party subcontractors, several of which the segment is required to work with by government edict. Under the contract, the segment is responsible for the performance of those subcontractors, many of which it does not control. The Defense segment's contracts and subcontracts contain the customary provision permitting termination at any time for the convenience of the government, with payment for any work completed, associated profit, and inventory/work in process at the time of termination. Materials used in the Defense segment are available from multiple sources. As of December 31, 2018, 170 employees of Amron, or 1 8 % of the Company’s and its subsidiaries’ total workforce, are members of the United Steel Workers union. The most recent contract between Amron and the union is effective through February 29, 2020.

Environmental [Abstract]
Environmental	K. ENVIRONMENTAL In May 1986, the Company’s Eau Claire, Wisconsin site was placed on the United States Environmental Protection Agency’s National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 because of hazardous waste deposited on the property. As of December 31, 1998, all remediation projects required at the Company's Eau Claire, Wisconsin site had been installed, were fully operational, and restoration activities had been completed. In addition, the Company is a member of a group of companies that may have disposed of waste into an Eau Claire area landfill in the 1960s and 1970s. After the landfill was closed, elevated volatile organic compounds were discovered in the groundwater. Remediation plans were established, and the costs associated with remediation and monitoring at the landfill are split evenly between the group and the City of Eau Claire. As of December 31, 2018, there does not appear to be exposure related to this site that would have a material impact on the operations or financial condition of the Company.  Based on factors known as of December 31, 2018, it is believed that the Company's existing environmental accrued liability reserve will be adequate to satisfy on-going remediation operations and monitoring activities both on- and off-site; however, should environmental agencies require additional studies, extended monitoring, or remediation projects, it is possible that the existing accrual could be inadequate. Management believes that in the absence of any unforeseen future developments, known environmental matters will not have any material effect on the results of operations or financial condition of the Company. The Company’s environmental accrued liability on an undiscounted basis was $ 1,120,000 and $ 1,150,000 as of December 31, 2018 and 2017, respectively, and is included in accrued liabilities on its balance sheet.  Expected future payments for environmental matters are as follows:     (In thousands)  Years Ending December 31:  2019 $ 230  2020 165  2021 150  2022 135  2023 120  Thereafter 320  $ 1,120

The Company identifies its segments based on the Company's organization structure, which is primarily by principal products. The principal product groups are Housewares/Small Appliance and Defense. Sales for both segments are primarily to customers in North America. On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. As a result of this transaction, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation and classified the assets and liabilities of its Absorbent Products business as held for sale. The operations of PAPI previously comprised the Company’s Absorbent Products segment. See Note P for further discussion.  The Housewares/Small Appliance segment designs, markets, and distributes housewares and small appliances. The housewares/small appliance products are sold primarily in the United States and Canada directly to retail outlets and also through independent distributors. As more fully described in Note J , the Company primarily sources its Housewares/Small Appliance products from non-affiliated suppliers located in the Orient. Sales are seasonal, with the normal peak sales period occurring in the fourth quarter of the year prior to the holiday season.  The Defense segment was started in 2001 with the acquisition of AMTEC Corporation, which manufactures precision mechanical and electromechanical assemblies for the U.S. Government and prime contractors. During 2005, and again during 2010, AMTEC Corporation was one of two prime contractors selected by the Army to supply all requirements for the 40mm family of practice and tactical ammunition cartridges for a period of five years. In 2016, AMTEC was awarded a one -year contract, and in 2017, it was awarded a third five -year contract as the sole prime contractor. AMTEC's manufacturing plant is located in Janesville, Wisconsin. Since the inception of the Defense segment in 2001, the Company has expanded the segment by making several strategic business acquisitions, and has additional facilities located in East Camden, Arkansas; Antigo, Wisconsin; Perry, Florida; and Clear Lake, South Dakota. During 2003, the segment was expanded with the acquisition of Spectra Technologies, LLC of East Camden, Arkansas. This facility performs Load, Assemble, and Pack (LAP) operations on ordnance-related products for the U.S. Government and prime contractors. During 2006, the segment was expanded with the acquisition of certain assets of Amron, LLC of Antigo, Wisconsin, which primarily manufactures cartridge cases used in medium caliber (20-40mm) ammunition. In 2011 the segment was further augmented with the purchase of certain assets of ALS Technologies, Inc. of Bull Shoals, Arkansas, which manufactures less lethal ammunitions. The Company subsequently relocated this operation to Perry, Florida, and in October of 2018, divested itself of the less lethal business. See Note Q for further explanation. During 2014, the Company continued the expansion of the Defense segment with the purchase of substantially all of the assets of Chemring Energetic Devices, Inc. located in Clear Lake, South Dakota, and all of the real property owned by Technical Ordnance Realty, LLC. The Clear Lake facility manufactures detonators, booster pellets, release cartridges, lead azide, and other military energetic devices and materials. The Defense segment’s collection of facilities enables the Company to deliver in virtually all aspects of the manufacture of medium caliber training and tactical rounds. They include the fuze, the metal parts including the cartridge case, the load, assemble and pack of the final round, and the detonator.  In the following summary, operating profit represents earnings before other income, income taxes, and discontinued operations. The Company's segments operate discretely from each other with no shared manufacturing facilities. Costs associated with corporate activities (such as cash and marketable securities management) and the assets associated with such activities are included within the Housewares/Small Appliance segment for all periods presented.

Discontinued Operations [Abstract]
Discontinued Operations	P. DISCONTINUED OPERATIONS On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. (“Drylock”) in exchange for $68,448,000 . The proceeds amount differs from the amount originally disclosed because of the customary post-closing adjustments that were finalized during the second quarter of 2017, totaling $1,448,000 .

As a result of the aforementioned transactions, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation, and classified the assets and liabilities of its Absorbent Products business as held for sale. The Company’s pre-tax gain on the sale of $11,413,000 , net of one-time transaction costs, was recorded in 2017 within earnings from discontinued operations. This amount differs from the gain originally reported as a result of the post-closing adjustments mentioned above that were finalized in the second quarter of 2017.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended

Summary Of Significant Accounting Policies [Abstract]
Use Of Estimates In The Preparation Of Financial Statements	(1) USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS: In preparation of the Company's Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and related revenues and expenses. Actual results could differ from the estimates used by management.
Basis Of Presentation	(2) BASIS OF PRESENTATION: The Consolidated Financial Statements include the accounts of National Presto Industries, Inc. and its subsidiaries, all of which are wholly-owned. All material intercompany accounts and transactions are eliminated. For a further discussion of the Company's business and the segments in which it operates, please refer to Note L .  On January 3, 2017, the Company and its wholly-owned subsidiary, Presto Absorbent Products, Inc. (“PAPI”), entered into an asset purchase agreement wherein substantially all PAPI assets were sold and certain liabilities were assigned to Drylock Technologies, LTD. (“Drylock”) in exchange for $68,448,000 . The proceeds amount differs from the amount originally disclosed because of the customary post-closing adjustments that were finalized during the second quarter of 2017, totaling $1,448,000 . The asset purchase agreement also provided for additional proceeds of $4,000,000 upon the sale of certain delayed assets, consisting of machinery and equipment that were the subject of an involuntary conversion. The sale of the delayed assets was consummated during the second quarter of 2018 and resulted in no gain or loss. As a result of the aforementioned transactions, the Company classified its results of operations for all periods presented to reflect its Absorbent Products business as a discontinued operation and classified the assets and liabilities of its Absorbent Products business as held for sale. See Note P for further discussion.
Reclassifications	(3) RECLASSIFICATIONS: Certain reclassifications have been made to the prior periods' financial statements to conform to the current period’s financial statement presentation. These reclassifications did not affect net earnings or stockholders’ equity as previously reported .
Fair Value Of Financial Instruments	(4) FAIR VALUE OF FINANCIAL INSTRUMENTS: The Company utilizes the methods of determining fair value as described in Financial Accounting Standard Board (“FASB”) Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures to value its financial assets and liabilities. ASC 820 utilizes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  The carrying amount for cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximates fair value due to the immediate or short-term maturity of these financial instruments. The fair value of marketable securities are discussed in Note A(5).
Cash Cash Equivalents And Marketable Securities	(5) CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES:  Cash and Cash Equivalents: The Company considers all highly liquid marketable securities with an original maturity of three months or less to be cash equivalents. Cash equivalents include money market funds. The Company deposits its cash in high quality financial institutions. The balances, at times, may exceed federally insured limits. Money market funds are reported at fair value determined using quoted prices in active markets for identical securities (Level 1, as defined by FASB ASC 820).  The Company's cash management policy provides for its bank disbursement accounts to be reimbursed on a daily basis. Checks issued but not presented to the bank for payment of $ 3,057,000 and $ 3,157,000 at December 31, 2018 and 2017, respectively, are included as reductions of cash and cash equivalents or b oo k overdrafts in accounts payable, as appropriate.  Marketable Securities: The Company has classified all marketable securities as available-for-sale which requires the securities to be reported at fair value, with unrealized gains and losses, net of tax, reported as a separate component of stockholders' equity. Highly liquid, tax-exempt variable rate demand notes with put options exercisable in three months or less are classified as marketable securities.  At December 31, 2018 and 2017, cost for marketable securities was determined using the specific identification method. A summary of the amortized costs and fair values of the Company's marketable securities at December 31 is shown in the following table. All of the Company’s marketable securities are classified as Level 2, as defined by FASB ASC 820, with fair values determined using significant other observable inputs, which include quoted prices in markets that are not active, quoted prices of similar securities, recently executed transactions, broker quotations, and other inputs that are observable.      (In thousands)  MARKETABLE SECURITIES   Amortized Cost Fair Value Gross Unrealized Gains Gross Unrealized Losses  December 31, 2018  Tax-exempt Municipal Bonds $ 40,156 $ 40,182 $ 44 $ 18  Variable Rate Demand Notes 94,416 94,416 - -  Total Marketable Securities $ 134,572 $ 134,598 $ 44 $ 18   December 31, 2017  Tax-exempt Municipal Bonds $ 30,103 $ 29,994 $ - $ 109  Variable Rate Demand Notes 114,258 114,258 - -  Total Marketable Securities $ 144,361 $ 144,252 $ - $ 109  Proceeds from sales and maturities of marketable securities totaled $ 173,060,000 in 2018, $ 132,752,000 in 2017, and $ 33,863,000 in 2016. There were no realized gross gains or losses related to sales of marketable securities during the years ended December 31, 2018, 2017 and 2016. Net unrealized gains (losses) included in other comprehensive income were $ 135,000 , $ (37,000) and $ (57,000) before taxes for the years ended December 31, 2018, 2017, and 2016, respectively. No unrealized gains or losses were reclassified out of accumulated other comprehensive income during the same periods.  The contractual maturities of the marketable securities held at December 31, 2018 are as follows: $ 21,787,000 within one year; $ 35,857,000 beyond one year to five years; $ 17,538,000 beyond five years to ten years, and $ 59,416,000 beyond ten years. All of the instruments in the beyond five year ranges are variable rate demand notes which, as noted above, can be tendered for cash at par plus interest within seven days . Despite the stated contractual maturity date, to the extent a tender is not honored, the notes become immediately due and payable.
Accounts Receivable	(6) ACCOUNTS RECEIVABLE: The Company's accounts receivable is related to sales of products. Credit is extended based on prior experience with the customer and evaluation of customers' financial condition. Accounts receivable are primarily due within 25 to 60 days. The Company does not accrue interest on past due accounts receivable. Receivables are written off only after all collection attempts have failed and are based on individual credit evaluation and the specific circumstances of the customer. The allowance for doubtful accounts represents an estimate of amounts considered uncollectible and is determined based on the Company's historical collection experience, adverse situations that may affect the customer's ability to pay, and prevailing economic conditions.
Inventories	(7) INVENTORIES: Housewares/Small Appliance segment inventories are stated at the lower of cost or net realizable value with cost being determined principally on the last-in, first-out (LIFO) method. Defense segment inventories are stated at the lower of cost and net realizable value determined principally on the first-in, first-out (FIFO) method. Inventoried costs relating to contracts in progress are stated at actual production costs, including factory overhead, initial tooling, and other related costs incurred to date, reduced by amounts associated with recognized sales, utilizing a standard costing type method. The Company evaluates inventories to determine if there are any excess or obsolete inventories on hand.
Property, Plant And Equipment	(8) PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment are stated at cost. Straight-line depreciation is provided in amounts sufficient to charge the costs of depreciable assets to operations over their service lives which are estimated at 15 to 40 years for buildings, 3 to 10 years for machinery and equipment, and 15 to 20 years for land improvements. The Company reviews long-lived assets consisting principally of property, plant, and equipment, for impairment when material events and changes in circumstances indicate the carrying value may not be recoverable. As a result of the divestiture of one of its operating facilities in the Defense segment during 2018, the Company recorded an impairment of $2,975,000 during the third quarter of 2018. See Note Q for further explanation. Approximately $264,000 of construction in progress in the Company’s Housewares/Small Appliance segment is presented on the Consolidated Balance Sheet as Machinery and Equipment at December 31, 2018, and approximately $1,437,000 of construction in progress in the Company’s Defense segment is presented on the Consolidated Balance Sheet as Buildings at December 31, 2018. The construction in progress is expected to be completed by the third quarter of 2019. Approximately $374,000 and $764,000 of construction in progress in the Company’s Defense segment is presented on the Consolidated Balance Sheet as Buildings and Machinery and Equipment, respectively, at December 31, 2017.
Goodwill	(9) GOODWILL: The Company recognizes the excess cost of acquired entities over the net amount assigned to the fair value of assets acquired and liabilities assumed as goodwill. Goodwill is tested for impairment on an annual basis at the start of the fourth quarter and between annual tests whenever an impairment is indicated, such as the occurrence of an event that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Impairment losses are recognized whenever the implied fair value of goodwill is less than its carrying value. No goodwill impairments were recognized during 2018, 2017, or 2016.  The Company's goodwill as of December 31, 2018 and 201 7 was $ 11,485,000 , rel ating entirely to its Defense segment, which had no cumulative impairment charges at December 31, 2018.
Intangible Assets	(10) INTANGIBLE ASSETS: Intangible assets primarily consist of the value of an acquired government sales contract and the value of trademarks and trade secrets. The intangible assets are all attributable to the Defense segment. The government sales contract intangible asset is amortized based on units fulfilled under the applicable contract, while the other intangible assets are amortized on a straight-line basis that approximates economic use, over periods ranging from 2 to 10 years. As of December 31, 2018, the Company determined that the trade secrets, which were acquired during 2017, had an indefinite life.  Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. As a result of the divestiture of one of its operating facilities in the Defense segment during 2018, the Company recorded an impairment of $46,000 during the third quarter of 2018. See Note Q for further explanation. Th ere were no impairments of intangible assets recognized during 2017 or 2016.  There were no intangible assets subject to amortization at December 31, 2018. The gross carrying amounts of the government sales contract and other intangible assets subject to amortization were $21,690,000 and $211,000 , respectively, totaling $21,901,000 at December 31, 2017. Accumulated amortization was $ 0 and $ 19,570,000 at December 31, 2018 and 2017, respectively. Amortization expense was $ 2,167,000 , $ 2,630,000 , and $ 721,000 during the years ended December 31, 2018, 2017, and 2016, respectively.
Other Assets	(11) OTHER ASSETS: Other assets includes prepayments that are made from time to time by the Company for certain materials used in the manufacturing process in the Housewares/Small Appliance segment. The Company expects to utilize the prepayments and related materials over an estimated period of up to two years. As of December 31, 2018 and 2017, $6,864,000 and $11,567,000 of such prepayments, respectively, remained unused and outstanding. At December 31, 2018 and 2017, $5,190,000 and $5,930,000 of these amounts, respectively, are included in Other Current Assets, representing the Company’s best estimate of the expected utilization of the prepayments and related materials during the twelve-month periods following those dates
Revenues	(12) REVENUES: The Company’s revenues are derived from short-term contracts and programs that are typically completed within 3 to 24 months and are recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers . The standard was adopted on January 1, 2018 and did not result in any material change to the Company’s pattern of revenue recognition. The Company’s contracts each contain one or more performance obligations: the physical delivery of distinct ordered product or products. The Company provides an assurance type product warranty on its products to the original owner. In addition, for the Housewares/Small Appliances segment, the Company estimates returns of seasonal products and returns of newly introduced products sold with a return privilege. Stand-alone selling prices are set forth in each contract and are used to allocate revenue to the corresponding performance obligations. For the Housewares/Small Appliances segment, contracts include variable consideration, as the prices are subject to customer allowances, which principally consist of allowances for cooperative advertising, defective product, and trade discounts. Customer allowances are generally allocated to the performance obligations based on budgeted rates agreed upon with customers, as well as historical experience, and yield the Company’s best estimate of the expected value for the variable consideration.  The Company's contracts in the Defense segment are primarily with the U.S. Department of Defense (DOD) and DOD prime contractors. As a consequence, this segment's business essentially depends on the product needs and governmental funding of the DOD. Substantially all of the work performed by the Defense segment directly or indirectly for the DOD is performed on a fixed-price basis. Under fixed-price contracts, the price paid to the contractor is awarded based on competition at the outset of the contract and therefore, with the exception of limited escalation provisions on specific materials, is generally not subject to any adjustments reflecting the actual costs incurred by the contractor.  For the Housewares/Small Appliance segment, revenue is generally recognized as the completed, ordered product is shipped to the customer from the Company’s warehouses. For the relatively few situations in which revenue should be recognized when product is received by the customer, the Company adjusts revenue accordingly. For the Defense segment, revenue is primarily recognized when the customer has legal title and formally documents that it has accepted the products. In some situations, the customer may obtain legal title and accept the products at the Company’s facilities, arranging for transportation at a later date, typically in one to four weeks. The Company does not consider the short-term storage of the customer owned products to be a material performance obligation, and no part of the transaction price is allocated to it.  The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, and customer advances and deposits (contract liabilities) on the Company’s Condensed Consolidated Balance Sheets. For the Defense segment, the Company occasionally receives advances or deposits from certain customers before revenue is recognized, resulting in contract liabilities. These advances or deposits do not represent a significant financing component. As of December 31, 2018 and 2017, $9,579,000 and $8,364,000 , respectively, of contract liabilities were included in Accounts Payable on the Company’s Condensed Consolidated Balance Sheets. The Company recognized revenue of $676,000 during 2018 that was included in the Defense segment contract liability at the beginning of the year. The Company monitors its estimates of variable consideration, which includes customer allowances for cooperative advertising, defective product, and trade discounts, and returns of seasonal and newly introduced product, all of which pertain to the Housewares/Small Appliances segment, and periodically makes cumulative adjustments to the carrying amounts of these contract liabilities as appropriate. During 2018 and 2017, there were no material adjustments to the aforementioned estimates. There were no material amounts of revenue recognized during the same periods related to performance obligations satisfied in a previous period. The portion of contract transaction prices allocated to unsatisfied performance obligations, also known as the contract backlog, in the Company’s Defense segment were $333,592,000 and $308,173,000 as of December 31, 2018 and 2017, respectively. The Company anticipates that the unsatisfied performance obligations will be fulfilled in an 18 to 24 -month period. The performance obligations in the Housewares/Small Appliances segment have original expected durations of less than one year.  The Company’s principal sources of revenue are derived from two segments: Housewares/Small Appliance and Defense, as shown in Note L . Management utilizes the performance measures by segment to evaluate the financial performance of and make operating decisions for the Company.
Advertising	(13) ADVERTISING: The Company's policy is to expense advertising as incurred and include it in selling and general expenses. Advertising expense was $ 181,000 , $ 174,000 , and $ 369,000 in 2018, 2017, and 2016, respectively.
Product Warranty	(14) PRODUCT WARRANTY: The Company’s Housewares/Small Appliance segment’s products are generally warranted to the original owner to be free from defects in material and workmanship for a period of 1 to 12 years from date of purchase. The Company allows a 60 -day over-the-counter initial return privilege through cooperating dealers. The Company services its products through a corporate service repair operation. The Company estimates its product warranty liability based on historical percentages which have remained relatively consistent over the years.  The product warranty liability is included in accounts payable on the balance sheet. The following table shows the changes in product warranty liability for the period:      (In thousands)  Year Ended December 31  2018 2017  Beginning balance January 1 $ 383 $ 543  Accruals during the period 315 268  Charges / payments made under the warranties (477) (428)  Balance December 31 $ 221 $ 383 
Stock-Based Compensation	(15) STOCK-BASED COMPENSATION: The Company accounts for stock-based compensation in accordance with ASC 718, Compensation — Stock Compensation . Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense ratably over the requisite service period, net of estimated forfeitures. As more fully described in Note F , the Company awards non-vested restricted stock to employees and executive officers.
Income Taxes	(16) INCOME TAXES: Deferred income tax assets and liabilities are recognized for the differences between the financial and income tax reporting bases of assets and liabilities based on enacted tax rates and laws. The deferred income tax provision or benefit generally reflects the net change in deferred income tax assets and liabilities during the year. The current income tax provision reflects the tax consequences of revenues and expenses currently taxable or deductible on various income tax returns for the year reported. Income tax contingencies are accounted for in accordance with FASB ASC 740, Income Taxes . See Note H for summaries of the provision, the effective tax rates, and the tax effects of the cumulative temporary differences resulting in deferred tax assets and liabilities. In December 2017, the United States enacted changes to its tax laws, which included a reduction of the corporate income tax rate from 35% to 21% , beginning in 2018. The reduction in the tax rate resulted in a revaluation of the Company’s deferred tax assets and liabilities held at December 31, 2017.
Recently Issued Accounting Pronouncements	(17) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS: In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements.  In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 provides guidance for estimating credit losses on certain types of financial instruments, including trade receivables, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance requires a modified retrospective transition method and early adoption is permitted. The Company does not expect the adoption of ASU 2016-13 to have a material impact on its consolidated financial statements.  In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company intends to adopt the new standard utilizing a modified retrospective method with no restatement of comparative periods, and also intends to elect the package of practical expedients, as well as the hindsight and short term lease practical expedients. The Company continues to evaluate the impact of the adoption of ASU 2016-02 on its consolidated financial statements. The evaluation includes identifying, cataloging, and categorizing its current leasing arrangements and evaluating new disclosure requirements. The Company estimates the adoption of the new standard will result in the recognition of ROU assets of approximately $4,000,000 , with corresponding lease liabilities of the same amount.  Other pronouncements issued but not effective until after December 31, 2018, are not expected to have a material impact on the Company's consolidated financial statements.
