FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS [Abstract]

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

NOTE 12: FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

The Company makes certain disclosures as detailed below with regard to financial instruments, including derivatives. These disclosures include, among other matters, the nature and terms of derivative transactions, information about significant concentrations of credit risk and the fair value of financial assets and liabilities.

The Company formally designates qualifying derivatives as hedge relationships (“hedges”) and applies hedge accounting when considered appropriate. The Company does not use derivative financial instruments for trading or speculative purposes.

A. Exchange Rate Transactions

As the functional currency of Tower is the USD and a portion of Tower’s expenses are denominated in NIS, Tower enters into exchange rate agreements from time to time to partially hedge the volatility of future cash flows caused by changes in foreign exchange rates on NIS-denominated expenses. In 2023, the exchange rate transaction-related derivatives were accounted for as hedge accounting resulting in gain or loss initially reported as a component of OCI and subsequently upon maturity reclassified into the statement of operations at the same time that the hedged item’s exposure results are recorded in the statement of operations.

As of December 31, 2023, the fair value amounts of such exchange rate agreements were $1,894 in an asset position, presented in other current assets with a face value of $156,000. As of December 31, 2022, the fair value amounts of such exchange rate agreements were $3,805 in a liability position, presented in other current liabilities with a face value of $157,000.

As the functional currency of the Company is the USD and a portion of TPSCo revenues and expenses are denominated in JPY, the Company enters into exchange rate agreements from time to time to partially hedge the volatility of future cash flows caused by changes in foreign exchange rates on JPY-denominated amounts. The related derivatives were accounted for as cash flow hedges resulting in gain or loss initially reported as a component of OCI and subsequently reclassified into the statement of operations at the same time that the hedged item’s exposure results are recorded in the statement of operations.

As of December 31, 2023, and 2022, the fair value amounts of such exchange rate agreements were $500 and $3,142, respectively, in a liability position, presented in other current liabilities and with a face value of $204,000 and $217,000, respectively.

Losses reclassified from other comprehensive income into net loss recognized in the Company’s consolidated statement of operations for the year ended December 31, 2023 were $5,153.

Losses reclassified from other comprehensive income into net loss recognized in in the Company’s consolidated statements of operations for the year ended December 31, 2022 were $36,857.

B. Concentration of Credit Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, bank deposits, marketable securities, derivatives, trade receivables and government and other receivables. The Company’s cash, deposits, marketable securities and derivatives are maintained with large and reputable banks and investment banks. The composition and maturities of investments are regularly monitored by the Company. Generally, these securities may be redeemed upon demand and bear minimal risk.

The Company generally does not require collateral for insurance of receivables; however, in certain circumstances, the Company obtains credit insurance or may require advance payments. An allowance for current expected credit losses is maintained with respect to trade accounts receivables and marketable securities. The Company performs ongoing credit evaluations of its customers and marketable securities.

C. Fair Value of Financial Instruments

The estimated fair values of the Company’s financial instruments, excluding debentures, do not materially differ from their respective carrying amounts as of December 31, 2023 and 2022.

The fair value of debentures, based on quoted market prices as of December 31, 2022, was approximately $19,000, same as their carrying amounts as of that date. As of March 31, 2023, the Series G Debentures were fully redeemed.

D. Designated Cash Flow Hedge Transactions

The Company entered into designated cash flow hedging transactions using a cross-currency swap to mitigate the foreign exchange rate changes’ impact on principal and interest arising from the Series G Debentures’ denomination in NIS.

As of December 31, 2022, the fair value of the swap was $1,685 in an asset net position and was presented in other current assets. The effective portions of $16 loss were recorded in OCI and recorded in earnings during the first three months of 2023.

For the year ended December 31, 2022, the hedging effect of the swap on the Company’s results of operations was a loss of $5,966, and was recognized as a financing loss, to offset the effect of the rate difference related to the Series G Debentures.

E. Fair Value Measurements

Valuation Techniques

In general, and where applicable, the Company uses quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to the Company’s Level 1 assets and liabilities. If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company’s Level 2 and Level 3 assets and liabilities.

Level 1 Measurements

Securities classified as available-for-sale are reported at fair value on a recurring basis. These securities are classified as Level 1 of the valuation hierarchy where quoted market prices from reputable third-party brokers are available in an active market. Changes in fair value of securities available-for-sale are recorded in other comprehensive income.

Level 2 Measurements

If quoted market prices are not available, or the prices of securities are derived from various sources, and do not necessarily represent the prices at which these securities could have been bought or sold, the Company obtains fair value measurements of these securities or of similar assets and liabilities from an independent pricing service. These securities are reported using Level 2 inputs and the fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors.

For cross-currency swap and derivatives measured under Level 2, the Company uses the market approach using quotations from banks and other public information.

Level 3 Measurements

Investments in equity securities of privately-held companies without readily determinable fair values are measured using the Measurement Alternatives (see Note 2J). The Company reviews these investments for impairment and observable price changes on a quarterly basis and adjusts the carrying value accordingly. For the year ended December 31, 2023, the Company did not record significant changes to the carrying value of such investments, and for the year ended December 31, 2022, the Company recorded a decrease of $6,978 in the carrying value of such investments, presented in other income (expense), net in the statements of operations.

B. Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with US GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Principals of Consolidation

C. Principals of Consolidation

The Company’s consolidated financial statements include the financial statements of Tower and its subsidiaries. The Company’s consolidated financial statements are presented after elimination of inter-company transactions and balances.

Reclassifications

D. Reclassifications

Certain prior year amounts have been reclassified to conform to the current financial statement presentation.

Cash and Cash Equivalents

E. Cash and Cash Equivalents

Cash and cash equivalents consist of cash, highly liquid bank deposits and money market funds readily convertible to known amounts of cash with original maturities of three months or less as of the date of its purchase.

Short Term Interest-Bearing Deposits

F. Short Term Interest-Bearing Deposits

Short-term deposits include bank deposits with original maturities greater than three months and with remaining maturities of less than one year. Such deposits are presented at cost, including accrued interest, which approximates their fair value.

Marketable Securities

G. Marketable Securities

The Company accounts for its investments in grade debt securities in accordance with ASC 320 "Investments - Debt Securities". Management determines the appropriate classification of its investments in debt securities at the time of purchase and re-evaluates such determinations at each balance sheet date.

The Company classifies its marketable securities as "available-for-sale", as the Company intends to hold them for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity, mix of the Company’s assets and liabilities, liquidity needs and other similar factors. Securities classified as available for sale are measured at fair value, based on quoted market prices or independent pricing services valuation. Gains and losses are recognized on a specific identification basis, in the Company's consolidated statements of operations.

Unrealized gains and losses are recorded in (i) the statement of other comprehensive income in periods the Company has no specific need and/or plan to use cash by selling such securities, or (ii) in the statement of operations as financing expense (income) in periods the Company has a specific need and/or intends to sell such securities.

The Company assessed the available-for-sales debt securities with an amortized cost basis in excess of estimated fair value to determine what amount of that difference, if any, is caused by expected credit losses in accordance with ASC 326, "Financial Instruments - Credit Losses".

Allowance for credit losses is recognized as a charge in financing income (expense), net, on the consolidated statements of operation, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive income in shareholders' equity.

The Company concluded that the current expected credit losses on its available-for-sale investment portfolio were immaterial.

Trade Accounts Receivable - Allowance for Expected Credit Loss

H. Trade Accounts Receivable - Allowance for Expected Credit Loss

The Company maintains an allowance based on specific analysis of each customer account receivable’s aging, assessment of its related risk and ability of the customer to make the required payment. In addition, in accordance with ASC 326, "Financial Instruments - Credit Losses", an allowance is maintained for such estimated expected losses. The amount of the allowance is determined principally on the basis of past collection experience and known financial factors regarding specific customers. Trade accounts receivables are written off using this allowance when it is probable that collection will not occur. Credit is extended to customers satisfying pre-defined credit criteria.

The total allowance for expected credit losses was $4,790 and $3,460 as of December 31, 2023 and 2022, respectively.

Inventories

I. Inventories

Inventories are stated at the lower of aggregate cost or net realizable value. If inventory costs exceed expected net realizable value, the Company writes-down the difference between the cost and the expected net realizable value. Cost of raw materials is determined mainly on the basis of the weighted average moving price per unit. Work in progress is measured at cost including acquisition costs, processing costs and other costs incurred in bringing the inventories to their present stage.

Investments in Privately Held Companies

J. Investments in Privately Held Companies

Long-term investments include equity investments in privately-held companies without readily determinable fair values. In accordance with ASC 321 - “Investments - Equity Securities”, the Company may elect to measure those investments at fair value or at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer (“Measurement Alternative”). The Company elected to use the Measurement Alternative for each of its investments. Any adjustments resulting from impairments and/or observable price changes are recorded under “other income (expense), net” in the consolidated statements of operations. See also Note 2M below.

Property and Equipment

K. Property and Equipment

The Company accounts for property and equipment in accordance with Accounting Standards Codification ASC 360 “Accounting for the Property, Plant and Equipment”. Property and equipment are presented at cost, including capitalizable costs. Capitalizable costs include only costs that are identifiable with, and related to, the property and equipment, and are incurred prior to their initial operation. Identifiable incremental direct costs include costs associated with constructing, establishing, and installing facilities and equipment, as well as technology transfer.

Maintenance and repairs are charged to expenses as incurred.

Property and equipment are presented net of investment grants received and less accumulated depreciation.

Depreciation is calculated based on the straight-line method over the Company’s estimated useful lives of the assets, as follows:

•

Buildings and building improvements, including facility infrastructure: 10-25 years

•

Machinery and equipment, software and hardware: 3-15 years.

Impairment charges, if needed, are determined based on the policy outlined in Note 2M below.

Property and equipment also include assets under capital leases, which are depreciated according to their applicable useful life.

Intangible Assets and Goodwill

L. Intangible Assets and Goodwill

The Company accounts for intangible assets and goodwill in accordance with ASC 350 “Intangibles-Goodwill and Other”. Intangible assets include the values assigned to the intangible assets as part of the purchase price allocation made at the time of acquisition. Intangible assets are amortized over the expected estimated economic life commonly used in the industry. Goodwill is not amortized and subject to impairment testing. Impairment charges on intangibles or goodwill, if needed, are determined based on the policy outlined in Note 2M below.

Impairment of Assets

M. Impairment of Assets

Impairment of Property, Equipment and Intangible Assets

The Company reviews long-lived assets and intangible assets on a periodic basis, as well as when such review is required based upon relevant circumstances, to determine whether events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, considering the undiscounted cash flows expected from them. If applicable, the Company recognizes an impairment loss based upon the difference between the carrying amount and the fair value of such assets, in accordance with ASC 360-10 “Property, Plant and Equipment”. As of December 31, 2023, the Company concluded there was no impairment to its long-lived assets and intangible assets.

Impairment of Goodwill

The Company performs a qualitative analysis when testing goodwill for impairment. A qualitative goodwill impairment test is performed when the fair value of a reporting unit historically has significantly exceeded the carrying value of its net assets and based on current operations is expected to continue to exceed it. Otherwise, the Company is required to conduct a quantitative impairment test and estimate the fair value of the reporting unit using a combination of an income approach based on discounted cash flow analysis and a market approach based on market multiples. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment charge is recorded for the difference. As of December 31, 2023, the Company performed a qualitative impairment test for its reporting unit and concluded there was no impairment of goodwill.

Impairment of Investment in Privately Held Companies

Investments in privately held companies accounted for using the Measurement Alternative are subject to periodic impairment reviews. Based on ASC 321-10-35-3, the Company’s impairment analysis considers qualitative factors to evaluate whether the investment is impaired. As of December 31, 2023, no impairments were recorded.

Leases

N. Leases

The Company recognize a right-of-use asset (“ROU”) and lease liability for all operating and capital leases with a term greater than twelve months upon lease arrangement inception.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the terms of lease contracts. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Since most of the Company’s leases do not provide an implicit rate, the Company's incremental borrowing rate is used based on the information available at the commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense. For additional information, see Notes 11D and 11E.

Revenue Recognition

O. Revenue Recognition

The Company recognizes revenue in accordance with ASC 606 “Revenue from Contracts with Customers“ when it transfers the control of promised goods or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The Company’s revenues are generated principally from sales of semiconductor wafers. The Company, to a much lesser extent, also derives revenues from design support and other technical and support services incidental to the sale of semiconductor wafers. Most of the Company’s sales are achieved through the effort of its direct sales and business development force.

Wafer sales typically contain a single performance obligation that is fulfilled on the date of delivery and recognized at a point in time, which is upon shipment of the Company’s products to unaffiliated customers, depending on shipping terms stipulated in the contract. Accordingly, control of the products transfers to the customer in accordance with the transaction's shipping terms. Taxes imposed by governmental authorities, such as sales taxes or value-added taxes, are excluded from net sales.

The Company provides for sales returns allowance relating to specified yield or quality commitments as a reduction of revenues, based on past experience and specific identification of relevant events, which has been in immaterial amounts.

The Company provides its customers with other services that are less significant in scope and amount and for which recognition occurs over time when customers receive the services.

Research and Development

P. Research and Development

Research and development costs are charged to operations as incurred. Amounts received or receivable from the government of Israel and others, such as participation in research and development programs, are offset from research and development costs. The accrual for grants receivable is determined based on the terms of the programs, provided that the criteria for entitlement have been met. As of December 31, 2023, the grants receivable amount was immaterial.

Income Taxes

Q. Income Taxes

The Company accounts for income taxes using an asset and liability approach as prescribed in ASC 740-10 “Income Taxes”. This topic prescribes the use of the liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities. Deferred taxes are measured using the enacted tax rates under applicable law effective for the year in which the differences are expected to reverse as of the balance sheet date. Deferred tax assets and liabilities, as well as any related valuation allowance, are classified as noncurrent items on the balance sheets.

The Company evaluates the potential realization of its deferred tax assets for each jurisdiction in which the Company operates at each reporting date and establishes valuation allowances when it is more likely than not that all or a part of its deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income of the same character and in the same jurisdiction. The Company considers all available positive and negative evidence in making this assessment, including, but not limited to, the scheduled reversal of deferred tax liabilities and deferred tax assets and projected future taxable income.

A valuation allowance is established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized based on all available evidence.

ASC 740-10 prescribes a two-step approach for recognizing and measuring uncertain tax positions. The first step is to evaluate tax positions taken or expected to be taken in a tax return by assessing whether they are more-likely-than-not sustainable, based solely on their technical merits including resolution of any related appeals or litigation process. The second step is to measure the associated tax benefit of each position as the largest amount that the Company believes is more-likely-than-not realizable. Differences between the amount of tax benefits taken or expected to be taken in its income tax returns and the amount of tax benefits recognized in its financial statements, represent the Company's unrecognized income tax benefits. The Company's policy is to include interest and penalties related to unrecognized income tax benefits as a component of income tax expense.

In December 2021, the OECD released Pillar Two model rules imposing on large multinational corporations, with revenue above €750 million, a minimum effective corporate income tax rate of 15% in every jurisdiction in which they operate. As of January 1, 2024, the rules have been enacted or partially enacted in certain jurisdictions in which the Company operates. The Company is studying the rules and its potential impact on its future consolidated financial statements and tax payments, including the rules’ transitional safe harbors, which may enable to postpone the application of the rules to the Company until after January 1, 2026.

Earnings per Ordinary Share

R. Earnings per Ordinary Share

Basic earnings per share are calculated in accordance with ASC 260, “Earnings Per Share” by dividing net profit or loss attributable to ordinary equity holders of Tower (the numerator) by the weighted average number of ordinary shares outstanding during the reported period (the denominator). Diluted earnings per share are calculated, if applicable, by adjusting net profit attributable to ordinary equity holders of Tower, and the weighted average number of ordinary shares, taking into effect all potential dilutive ordinary shares.

Comprehensive Income

S. Comprehensive Income

In accordance with ASC 220 “Comprehensive Income”, comprehensive income represents the change in shareholders’ equity during a reporting period from transactions and other events and circumstances from non-owner sources. It includes all changes in equity during a reporting period except those resulting from investments by owners and distributions to owners. Other comprehensive income (“OCI”) represents gains and losses that are included in comprehensive income but excluded from net profit.

Functional Currency and Exchange Rate Results

T. Functional Currency and Exchange Rate Results

The currency of the primary economic environment in which Tower, TSSA, TSNB and TSIT conduct their operations is the U.S. Dollar (“dollar”). Thus, the dollar is their functional and reporting currency. Accordingly, monetary accounts maintained in currencies other than the dollar are re-measured into dollars in accordance with ASC 830-10 “Foreign Currency Matters”. All transaction gains and losses from the re-measurement of monetary balance sheet items are reflected in the statements of operations as financial income or expenses, as appropriate. The financial statements of TPSCo, whose functional currency is the Japanese Yen (“JPY”), have been translated into dollars. The assets and liabilities have been translated using the exchange rate in effect as of the balance sheet date. The statements of operations of TPSCo have been translated using the average exchange rate for the reported period. The resulting translation adjustments are charged or credited to OCI.

Stock-Based Compensation

U. Stock-based Compensation

The Company applies the provisions of ASC Topic 718 “Compensation - Stock Compensation”, under which employees’ share-based equity awards (mostly restricted stock units and performance unit shares) are recognized based on the grant-date fair values.

The compensation costs are recognized using the graded vesting attribution method based on the vesting terms of each unit included in the award resulting in an accelerated recognition of compensation costs.

Fair value Measurements of Financial Instruments

V. Fair Value Measurements of Financial Instruments

ASC 820, "Fair Value Measurements and Disclosures" (“ASC 820”), requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

ASC 820 prioritizes the inputs into three levels that may be used to measure fair value:

Level 1

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

The carrying value of the Company’s bank deposits, account receivables, payables and accrued liabilities, approximate their current fair values in accordance with their nature and respective maturity dates or durations. The Company had no financial assets or liabilities carried and measured on a non-recurring basis during the reporting periods. Financial assets and liabilities measured on a recurring basis are those that are adjusted to fair value each time a financial statement is prepared such as marketable securities and investments in privately-held companies.

Derivatives and Hedging

W. Derivatives and Hedging

In accordance with ASC Topic 815, Derivative and Hedging ("ASC 815"), the Company recognizes all its derivative instruments as either assets or liabilities and carries them at fair value.

For derivative instruments that are designated and qualify as cash flow hedges, the derivative's gain or loss is initially reported as a component of OCI and is subsequently reclassified into earnings when the hedged exposure affects earnings, in the same line item as the underlying hedged item on the consolidated statements of earnings.

Cash flow hedges related to anticipated transactions are designated and documented at the inception of each hedge. Cash flows from hedging transactions are classified in the same categories as the cash flows from the respective hedged items.

Recently Adopted Accounting Pronouncements

X. Recently Adopted Accounting Pronouncements

The Company did not adopt any new standards or updates issued by the Financial Accounting Standards Board (“FASB”) during the fiscal year of 2023 that had a material impact on the Company’s financial position, results of operations, cash flows or financial statement disclosures.

Recently Issued Accounting Pronouncements Not Yet Adopted

Y. Recently Issued Accounting Pronouncements Not Yet Adopted

On December 23, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09— Income taxes (topic 740): improvements to income tax disclosures.

Rate reconciliation:

The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). Specifically, public business entities are required to disclose a tabular reconciliation, using both percentages and reporting currency amounts.

Income Taxes Paid:

The amendments in this Update require that all entities disclose on an annual basis the following information about income taxes paid: (1) The amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes and (2) The amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received).

Other Disclosures:

The amendments in this Update require that all entities disclose the following information: (1) income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and (2) income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The amendments in this Update eliminate the requirement for all entities to (A) disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or (B) make a statement that an estimate of the range cannot be made. The amendments in this Update remove the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. The amendments in this Update replace the term public entity as currently used in Topic 740 with the term public business entity as defined in the Master Glossary of the Codification.

The amendments should be effective for annual periods beginning after December 15, 2024. The Company does not expect the new standard to have a material impact on its consolidated financial statements.

C. Long-term JPY Loans

In December 2021, TPSCo refinanced its then existing loan with an 11 billion JPY (approximately $78,000 as of December 31, 2023) asset-based loan with a consortium of financial institutions consisting of (i) JA Mitsui Leasing, Ltd., (ii) Mitsubishi HC Capital Inc., (iii) Taishin International Bank Co., Ltd. Tokyo Branch, and (iv) BOT lease Co. Ltd. (“2021 JPY Loan”). The 2021 JPY Loan carries a fixed interest rate of 1.95% per annum with principal payable in seven semiannual payments from December 2024 until December 2027. The 2021 JPY Loan is secured mainly by a lien over the machinery and equipment of TPSCo located in the Uozu and Tonami facilities.

In September 2023, TPSCo entered into a term loan agreement with JA Mitsui Leasing Ltd. for an additional 3.5 billion JPY (approximately $25,000 as of December 31, 2023) term loan (“2023 JPY Loan”). The 2023 JPY Loan carries a fixed interest rate of 1.95% per annum with principal payable in seven semiannual payments from September 2024 until September 2027. The 2023 JPY Loan is secured by a second lien over the machinery and equipment of TPSCo located in the Uozu and Tonami facilities.

The 2021 JPY Loan and 2023 JPY Loan contain certain financial ratios and covenants, as well as customary definitions of events of default and acceleration of the repayment schedule. TPSCo’s obligations pursuant to the JPY Loans are not guaranteed by Tower, NTCJ, or any of their affiliates.

As of December 31, 2023, TPSCo maintained compliance with all of the financial covenants under the 2021 JPY Loan and 2023 JPY Loan.

D. Capital Lease Agreements and Other Long-term Liabilities

Certain of the Company’s subsidiaries enter into capital lease agreements from time to time for certain machinery and equipment, usually for a period of four years, with an option to buy the machinery and equipment after a period of between three to four years from the start of the lease period. The lease agreements are denominated in JPY and contain annual interest rates of approximately 2%, and the assets under the lease agreements are pledged to the lender until the time at which the respective subsidiary acquires the assets. The obligations under the capital lease agreements are guaranteed by Tower, except for TPSCo’s obligations under its capital lease agreements (see also Note 14B).

TPSCo leases its facility buildings in Japan from NTCJ under a long-term capital lease with a term through at least March 2032.

As of December 31, 2023 and 2022, the Company’s total outstanding capital lease liabilities for fixed assets were $118,272 and $158,114, respectively, of which $40,330 and $39,610, respectively, were included under current maturities of long-term debt.

Stockholders' Equity Note [Abstract]

SHAREHOLDERS' EQUITY

NOTE 15: SHAREHOLDERS’ EQUITY

A. Description of Ordinary Shares

As of December 31, 2023, Tower had 150 million authorized ordinary shares, par value NIS 15.00 each, of which approximately 111 million were outstanding. Holders of ordinary shares are entitled to participate equally in the payment of cash dividends and bonus share (stock dividend) distributions and, in the event of the liquidation of Tower, in the distribution of assets after satisfaction of liabilities to creditors. Each ordinary share is entitled to one vote on all matters to be voted on by shareholders.

B. Equity Incentive Plans

(1) Tower’s 2013 Share Incentive Plan (the “2013 Plan”)

In 2013, the Company adopted a share incentive plan for directors, officers and employees of the Company (“2013 Plan”).

Under the 2013 Plan, the Company granted, in 2023 and 2022, a total of 0.80 million restricted stock units (“RSUs”) and 0.61 million RSUs, respectively, to its employees and directors (including the below-described grants to the CEO and directors), with vesting periods of up to three years. Such RSUs amounts noted include performance based RSUs (“PSUs”). The Company determines compensation expenses of the RSUs based on the closing market price of the ordinary shares immediately prior to the date of grant and amortizes it over the applicable vesting period, taking into consideration achievement, if any, of performance criteria.

During 2023, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan:

(i) 75.8 thousand time-vested RSUs and 125.0 thousand PSUs, subject also to time-vesting, to the CEO, with 33% of such RSUs and PSUs to vest at the end of each year for 3 years following the grant date. The total compensation value of these RSUs was approximately $7,537. As was approved by shareholders in 2019, the grant also included a provision requiring the CEO to own, commencing May 2024, ordinary shares of the Company at a minimum value that equals at least three times his annual base salary as of May 2024 (the “Minimum Holding”). The CEO has until May 2024 to accumulate the Minimum Holding (whether by conversion of RSUs to ordinary shares or by purchase of ordinary shares), and during such period, until he accumulates the Minimum Holding, he must retain at least 20% of the vested time-based RSUs granted to him on or after May 2019;

(ii) 8.0 thousand time-vested RSUs to the chairman of the Board of Directors (“the Chairman”) for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and

(iii) 3.3 thousand time-vested RSUs to each of the seven members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $875, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant.

As was approved by shareholders in 2020, commencing July 2025, the members of the Board will have to own ordinary shares of the Company at a minimum value that equals at least 50% of their annual base fee and the Chairman will have to own ordinary shares of the Company at a minimum value that equals at least 50% of his annual cash compensation (the “BOD Minimum Holding”). The Chairman and the members of the Board have until July 2025 to accumulate the BOD Minimum Holding (whether by conversion of RSUs to ordinary shares or by purchase of ordinary shares), and during such period, until they accumulate the BOD Minimum Holding, they must retain at least 20% of the vested time-based RSUs granted to him/her on or after July 2020.

During 2022, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan:

(i) 59 thousand time-vested RSUs and 97 thousand PSUs, subject also to time-vesting, to the CEO, with 33% of such RSUs and PSUs to vest at the end of each year for 3 years following the grant date. Total compensation value of these RSUs was approximately $7,200. As was approved by shareholders in 2019, the grant also includes the Minimum Holding requirement defined above;

(ii) 6.5 thousand time-vested RSUs to the Chairman for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and

(iii) 2.7 thousand time-vested RSUs to each of the seven members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $875, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant.

As was approved by shareholders in 2020, the grants to the Chairman and the members of the Board includes the BOD Minimum Holding requirement defined above.

During 2021, the Company's CEO and members of the Board of Directors were awarded the following RSUs under the 2013 Plan:

(i) 80 thousand time-vested RSUs and 132 thousand PSUs, subject also to time-vesting, to the CEO, with 33% of such RSUs and PSUs to vest at the end of each year for 3 years following the grant date. Total compensation value of these RSUs was approximately $6,000. In addition, the Company's CEO was awarded 31 thousand PSUs that would vest upon attainment of certain performance conditions and not before one year from the date of grant, with a compensation value of approximately $1,000. As was approved by shareholders in 2019, the grant also includes the Minimum Holding requirement defined above;

(ii) 10.3 thousand time-vested RSUs to the Chairman for a total compensation value of $300, to vest 33% at the end of each year for 3 years following the grant date; and

(iii) 4.3 thousand time-vested RSUs to each of the seven members of the Board of Directors then serving (other than to the Chairman and the CEO), for an aggregate compensation value of $875, vesting over a two-year period, with 50% vesting on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant.

EMPLOYEE RELATED LIABILITIES

12 Months Ended

Dec. 31, 2023

Postemployment Benefits [Abstract]

EMPLOYEE RELATED LIABILITIES

NOTE 13: EMPLOYEE RELATED LIABILITIES

A. Employee Termination Benefits

Israeli law, labor agreements and corporate policy determine the obligations of Tower to make severance payments to dismissed Israeli employees and to Israeli employees leaving employment under certain circumstances. Generally, the liability for severance pay benefits, as determined by Israeli law, is based upon length of service and the employee’s monthly salary. This liability is primarily covered by regular deposits made each month by Tower into recognized severance and pension funds and by insurance policies maintained by Tower, based on the employee’s salary for the relevant month.

Commencing January 1, 2005, Tower implemented a labor agreement with regard to most of its Israeli employees, according to which monthly deposits into recognized severance and pension funds or insurance policies will release it from any additional severance obligation in excess of the balance in such accounts to such Israeli employees and, therefore, Tower incurs no liability or asset with respect to such severance obligations and deposits, since that date. Any net severance amount as of such date will be released on the employee’s termination date. Payments relating to Israeli employee termination benefits were $5,752, $6,269 and $5,941 for 2023, 2022 and 2021, respectively.

TPSCo established a Defined Contribution Retirement Plan (the “DC Plan”) for its employees who elected to join the plan through which TPSCo contributed approximately 8.2% in 2023, 8.5% in 2022 and 7.7% in 2021, with employee average match of 0.7% of employee base salary to the DC Plan. Other employees may elect to get the contribution in cash. The contribution releases the employer from further obligation to any payments upon termination of employment. The contribution is remitted to third party benefit funds based on employee preference. Total payments for retirement in 2023, 2022 and 2021 amounted to $4,266, $4,838 and $5,331 respectively.

B. TSNB Employee Benefit Plans

The following information provides the changes in 2023, 2022 and 2021 periodic expenses and benefit obligations due to the bargaining agreement signed between TSNB and its collective bargaining unit employees.

The plan’s assets measured at fair value on a recurring basis consisted of the following as of December 31, 2022:

Details	Level 1		Level 2		Level 3
Investments in commingled funds	$	-	$	19,511	$	-
Total plan assets at fair value	$	-	$	19,511	$	-

TSNB’s pension plan weighted average asset allocations on December 31, 2023, by asset category are as follows:

Asset Category	December 31, 2023			Target allocation 2024
Equity securities		10	%		10	%
Debt securities		90	%		90	%
Total		100	%		100	%

TSNB’s primary policy goals regarding the plan’s assets are to (1) provide liquidity to meet the Plan benefit payments and expenses payable from the Plan, (2) offer reasonable probability of achieving growth of assets that will assist in closing the Plan’s funding gap, and (3) manage the Plan’s assets in a liability framework. Plan assets are currently invested in commingled funds with various debt and equity investment objectives. The target asset allocation for the plan assets is 90% debt, or fixed income securities, and 10% equity securities. Individual funds are evaluated periodically based on comparisons to benchmark indices and peer group funds, and investment decisions are made by TSNB in accordance with the policy goals. Actual allocation to each asset category fluctuates and may not be within the target allocation specified above due to changes in market conditions.

The estimated expected return on assets of the plan is based on assumptions derived from, among other things, the historical return on assets of the plan, the current and expected investment allocation of assets held by the plan and the current and expected future rates of return in the debt and equity markets for investments held by the plan. The obligations under the plan could differ from the obligation currently recorded, if management's estimates are not consistent with actual investment performance.

NOTE 14: COMMITMENTS AND CONTINGENCIES

A. Liens

Loans, and Capital Leases

For liens under TPSCo’s JPY Loans, see Note 11C. For liens under the capital lease agreements, see Note 11D.

B. TPSCo

1. Renewed Contracts

In August 2022, Tower, TPSCo and NTCJ extended certain agreements with respect to TPSCo through March 2027 under certain amended terms, including changes to the commercial pricing for the services provided by TPSCo and enhanced financial support from Tower and NTCJ to TPSCo.

2. Japanese Operations Restructuring

In accordance with agreements signed in 2019, as amended thereafter, between Tower, NTCJ and TPSCo, it was decided to re-organize and re-structure TPSCo’s operations in Japan and maintain operations at the Uozu and Tonami facilities unchanged, while the Arai facility, which provided products solely to NTCJ and did not serve the Company’s customers, would cease operations. The cessation of operations of the Arai facility occurred in June 2022, and during 2022, TPSCo initiated the process of transferring a portion of the machinery and equipment from the Arai facility to the Tonami facility.

The remaining machinery and equipment were sold to third parties. The restructuring process, including the transfer and installation of machinery and equipment in the Tonami facility and the sale of certain equipment, was completed during the first half of 2023 and resulted in total restructuring gain, net from the sale of machinery and equipment of $72,411 as well as total restructuring expenses of $30,346.

For the year ended December 31, 2023, the Company recorded restructuring gain from the sale of machinery and equipment, net, of $52,168 as well as restructuring expense of $19,662.

For the year ended December 31, 2022, the Company recorded restructuring gain from the sale of machinery and equipment, net, of $20,243 as well as restructuring expense of $10,684.

Changes in accruals related to the Arai facility cessation for the year ended December 31, 2023 were as follows:

Details	Asset disposal accrual			Other Restructuring costs accrual
Accrued balance as of January 1, 2022	$	2,250		$	-

C. License Agreements

The Company enters into intellectual property and licensing agreements with third parties from time to time. The effect of each of them on the Company’s total assets and results of operations is immaterial. Certain of these agreements call for royalties to be paid by the Company to these third parties.

D. TSNB Lease Agreement

TSNB leases its facilities under an operational lease contract that is due to expire in the first quarter of 2027. In amendments to its lease, (i) TSNB secured various contractual safeguards designed to limit and mitigate any adverse impact of construction activities on its operations; and (ii) certain obligations of TSNB and the landlord are specified, including certain noise abatement actions at the facility. The landlord has made claims that TSNB’s noise abatement efforts are not adequate under the terms of the amended lease, and has requested a judicial declaration that TSNB has committed material non-curable breach of the lease that under the lease, may entitle the landlord to terminate the lease. TSNB does not agree and is disputing these claims.

E. Definitive Agreement with ST Microelectronics

In 2021, TSIT, Tower’s wholly-owned Italian subsidiary, entered into a definitive agreement with ST Microelectronics (“ST”) to share under collaborative arrangement a 300mm facility with ST in Agrate, Italy. The parties will share the cleanroom space and the facility infrastructure, with the Company installing its own equipment in one-third of the total space. TSIT and ST will invest in their respective process equipment, and work to accelerate the process flows’ transfer to the facility, product development, qualification and subsequent ramp-up. Operations will continue to be managed by ST. TSIT is currently installing certain tools in the Agrate facility and developing certain processes and technologies that it expects to qualify and ramp-up at said facility.

F. Foundry Agreement with Intel

In September 2023, Tower and Intel signed an agreement under which Tower will have a capacity corridor in Intel’s 300mm facility in New Mexico, USA. Under this agreement, Tower will invest up to $300,000 for equipment and other fixed assets to be owned by Tower and installed and qualified for Tower processes in this Intel’s facility.

G. Other Agreements

From time to time, in the ordinary course of business, the Company enters into long-term agreements with various entities for the joint development of product IPs and processes. The developed IPs may be owned separately by either the other entity or the Company, or owned jointly by both parties, as applicable.

Notes Payable [Abstract]
LONG-TERM DEBT - SERIES G DEBENTURES	NOTE 10: LONG-TERM DEBT - SERIES G DEBENTURES In June 2016, Tower raised approximately $115,000 through the issuance of long-term unsecured non-convertible debentures (“Series G Debentures”). The Series G Debentures were payable in seven semi-annual consecutive equal installments from March 2020 to March 2023 and carried an annual interest rate of 2.79%. The principal and interest amounts were denominated in NIS and were not linked to any index or to any other currency. The Company entered into cash flow hedging transactions to mitigate the foreign exchange rate changes’ impact on the principal and interest using a cross-currency swap. As of March 31, 2023, the Series G Debentures were fully redeemed.
