Summary of Significant Accounting Policies | NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Company consolidates those entities in which it, through the existing owners, has control over significant operating, financial or investing decisions of the entity. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company follows ASC 810-10-15 guidance with respect to accounting for variable interest entities (“VIE”). These entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support from other parties or whose equity investors lack any of the characteristics of a controlling financial interest. A variable interest is an investment or other interest that will absorb portions of a VIE’s expected losses or receive portions of its expected returns and are contractual, ownership or pecuniary in nature and that change with changes in the fair value of the entity’s net assets. A reporting entity is the primary beneficiary of a VIE and must consolidate it when that party has a variable interest, or combination of variable interests, that provide it with a controlling financial interest. A party is deemed to have a controlling financial interest if it meets both of the power and loss/benefits criteria. The power criterion is the ability to direct the activities of the VIE that most significantly impact its economic performance. The losses/benefits criterion is the obligation to absorb losses from, or right to receive benefits from, the VIE that could potentially be significant to the VIE. The VIE model requires an ongoing reconsideration of whether a reporting entity is the primary beneficiary of a VIE due to changes in the facts and circumstances. Northern Fire Management Services, LLC (“NFMS, LLC”): The Company assisted in designing and organizing NFMS, LLC with a business purpose of employing Canadian aviation professionals to provide services to the Company. A master services agreement exists between NFMS, LLC and the Company, Bridger Air Tanker, LLC, a wholly owned subsidiary of the Company, to transfer all annual expenses incurred to the Company in exchange for the Canadian employees to support the Company’s water scooper aircraft. NFMS, LLC is 50% owned by a Canadian citizen, and 50% owned by Bridger Aerospace Group, LLC (“BAG, LLC”). NFMS, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s responsibility for all decisions related to NFMS, LLC’s expenditures. Accordingly, NFMS, LLC has been consolidated by the Company for the years ended December 31, 2023 and 2022 and all intercompany expenses associated with NFMS, LLC and its service agreement have been eliminated in consolidation. For the years ended December 31, 2023 and 2022, NFMS, LLC’s assets and liabilities were immaterial to the Company’s financial statements. Mountain Air, LLC (“MA, LLC”): As of November 7, 2022, MA, LLC is a wholly-owned subsidiary of Bridger. Prior to MA, LLC becoming a wholly-owned subsidiary of the Company, MA, LLC was owned 50% by Timothy Sheehy, the Chief Executive Officer and a director of Bridger, and 50% by an entity affiliated with Matthew Sheehy, a director of Bridger. MA, LLC is a Federal Aviation Administration (“FAA”) part 135 certificate holder and is designed to hold aerial firefighting contracts. Bridger Aviation Services, LLC (“Bridger Aviation”), a wholly-owned subsidiary of Bridger, was a party to a certain Management Services Agreement (the “Aviation Agreement”), dated April 13, 2018, with MA, LLC. Pursuant to the Aviation Agreement, Bridger Aviation leased certain aircraft to MA, LLC. MA, LLC operated the aircraft and paid Bridger Aviation a fee equal to 99% of all revenue it received from the use and deployment of Bridger Aviation’s aircraft. MA, LLC was obligated to operate and maintain the aircraft in accordance with applicable FAA standards. MA, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s substantial control. Accordingly, the Company consolidated MA, LLC for the periods prior to November 7, 2022 and all intercompany expenses associated with MA, LLC and its Aviation Agreement were eliminated in consolidation. On November 17, 2023, we entered into a series of agreements designed to facilitate the purchase and return to service of four Canadair CL-215T Amphibious Aircraft (the “Spanish Scoopers”) originally awarded to our wholly-owned subsidiary, Bridger Aerospace Europe, S.L.U. (“BAE”), in September 2023 via a public tender process from the Government of Spain for €40.3 million. Under the terms of the agreements, we agreed to sell the entire outstanding equity interest in BAE to MAB and purchase $4.0 million of non-voting Class B units of MAB. We also entered into a services agreement with MAB whereby we will manage the return to service upgrades of the Spanish Scoopers through our wholly-owned Spanish subsidiary, Albacete Aero, S.L., while they are owned and funded by MAB. The service agreement also provides that we have the right, but not the obligation, to acquire each Spanish Scooper as it is ready to be contracted and returned to service. The Company assessed both MAB and BAE for variable interest entity accounting under ASC 810-10-15 and determined that MAB is a voting interest entity and BAE is a variable interest entity. However, neither entity is consolidated in the consolidated financial statements as the Company does not have a controlling financial interest in MAB and the Company is not the primary beneficiary of BAE. Accordingly, neither of these entities have been consolidated in the consolidated financial statements of the Company for the year ended December 31, 2023. Refer to “Note 17 – Commitments and Contingencies” included in this Annual Report on Form 10-K for additional details. Seasonality The Company’s business is generally seasonal, with a significant portion of total revenue occurring during the second and third quarters of the fiscal year due to the North American fire season. However, the weather dependency and seasonal fluctuation in the need to fight wildfires based upon location and the varying intensity of the fire season may lead our operating results to fluctuate significantly from quarter to quarter and year to year. Use of Estimates The preparation of financial statements in conformity with GAAP, requires management to make assumptions and estimates that affect the reported amounts of assets and liabilities, disclosure of gain or loss contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from their estimates and such differences could be material to the consolidated financial statements. Significant items subject to such estimates and assumptions include: (a) excess and aging aircraft support parts reserves, (b) allowance for doubtful accounts, (c) useful lives of property, plant and equipment, net, (d) allocation of the purchase price to the fair value of assets acquired and liabilities assumed, (e) impairment of long-lived assets, goodwill and other intangible assets, (f) disclosure of fair value of financial instruments, (g) variable interest entities, (h) accounting for Series A Preferred Stock and Legacy Bridger Series C Preferred Shares, (i) revenue recognition, (j) estimates and assumptions made in determining the carrying values of goodwill, other intangible assets, and contingent consideration and (k) Public Warrants and Private Placement Warrants. Cash and Cash Equivalents Cash and cash equivalents consist of cash and all highly liquid, readily convertible investments with a maturity of three months or less. Cash equivalents are placed primarily in time deposits and money market funds due in three months or less. The Company’s subsidiaries generally maintain cash account balances sufficient to meet their short-term working capital requirements and periodically remit funds to the parent company to pay intercompany lease, maintenance and other charges. Substantially all of the Company’s cash is concentrated in a few financial institutions. At times, deposits in these institutions exceed the federally insured limits. Restricted Cash Restricted cash includes cash and cash equivalents that are not readily available for use in the Company’s operating activities. The Company had $14.0 million and $12.3 million of restricted cash as of December 31, 2023 and 2022, respectively. These funds are held in a demand deposit account or highly rated money market fund. The Company had $14.0 million and $9.3 million in restricted cash related to the Series 2022 Bonds and zero and $3.0 million of restricted cash held in escrow as of December 31, 2023 and 2022, respectively. Investments in Marketable Securities Investments in debt securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income. Gains and losses are recognized when realized. Unrealized losses are evaluated for impairment to determine if the impairment is credit related. An other-than-temporary credit impairment would be recognized as an adjustment to income. Gains and losses are determined using the first-in first-out method. Investments in marketable securities are classified as current assets with short-term maturities of less than one year. Accounts and Note Receivable Accounts receivable consist of amounts due from our customers. The Company maintains an allowance for doubtful accounts equal to the estimated losses expected to be incurred based upon a review of the outstanding accounts receivable, historical collection information and existing economic conditions. For the years ended December 31, 2023 and 2022, the Company did not record any bad debt expense as accounts receivable have historically been collected in accordance with the policy and there is no history of write-offs. Notes receivable consists of a promissory note to pay a specific sum, with interest, within a defined period. Each reporting period, the Company evaluates the collectability of the outstanding note receivable balance. If the promissory note is deemed uncollectible, the Company will record the value of the note and the accrued interest as bad debt expense. For the years ended December 31, 2023 and 2022, the Company did not record any bad debt expense based on the assessment of the receivable. Aircraft Support Parts Aircraft support parts consist of repairables and expendables that are used for servicing aircraft and support parts for universal application amongst the aviation fleet. Aircraft support parts are tracked by serial number and capitalized at cost in the Consolidated Balance Sheets and expensed in the Consolidated Statements of Operations when used in operations. Property, Plant and Equipment, net Property, plant and equipment are recorded at cost when acquired. Except for aircraft, engines and rotable parts, depreciation is computed on the straight-line basis over the estimated useful life of property, plant and equipment and is recorded in Cost of revenues and Selling, general and administrative expense in the Consolidated Statements of Operations. Depreciation for aircraft, engines and rotable parts is recorded over the estimated useful life based on flight hours. The table below summarizes depreciable lives by asset category: Estimated Useful Life Aircraft, engines and rotable parts 1,500 – 6,000 flight hours Vehicles and equipment 3 – 5 years Buildings 40 years Aircraft undergo maintenance activities including routine repairs, inspections, part replacements and overhauls as required by regulatory authorities or manufacturer specifications. Costs of routine maintenance of aircraft are expensed as incurred as Cost of revenues in the Consolidated Statements of Operations. Costs that increase the value of the aircraft are capitalized as Property, plant and equipment, net in the Consolidated Balance Sheets and are depreciated over the asset’s useful life. Upon retirement or sale, the property, plant and equipment disposed of and the related accumulated depreciation are removed from the Consolidated Balance Sheets and any resulting gain or loss is recorded as Selling, general and administrative expense in the Consolidated Statements of Operations. Interest on long-term debt for the development or manufacturing of Company assets is capitalized to the asset until the asset enters production or use, and thereafter all interest is charged to expense as incurred. Business Combinations The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting in accordance with ASC 805, Business Combinations . Under the acquisition method of accounting, amounts paid for the acquisition are allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition inclusive of identifiable intangible assets. Acquisition consideration includes contingent consideration with payment terms based on the achievement of certain targets of the acquired business. The estimated fair value of identifiable assets and liabilities, including intangibles, are based on valuations that use information and assumptions available to management. The Company allocates any excess purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. Significant management judgments and assumptions are required in determining the fair value of assets acquired and liabilities assumed, particularly acquired intangible assets, including estimated useful lives. The valuation of purchased intangible assets is based upon estimates of the future performance and discounted cash flows of the acquired business. Each asset acquired or liability assumed is measured at estimated fair value from the perspective of a market participant. Contingent consideration represents an obligation of the acquirer to transfer additional assets or equity interests to the seller if future events occur or conditions are met, is recognized when probable and reasonably estimable. Contingent consideration recognized is included in the initial cost of the assets acquired and recorded in Accrued expenses and other current liabilities and Long-term accrued expenses and other noncurrent liabilities in the Consolidated Balance Sheets. Subsequent changes in the estimated fair value of contingent consideration are recognized as Selling, general and administrative expenses in the Consolidated Statements of Operations. Intangible Assets Intangible assets consist of finite-lived intangible assets acquired through the Company’s historical business combinations and software developed for internal-use. In accordance with ASC Topic 350-40, Software - Internal-Use Software , the Company capitalizes certain direct costs of developing internal-use software that are incurred in the application development stage, when developing or obtaining software for internal use. Once the internal use software is ready for its intended use, it is amortized on a straight-line basis over its useful life. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Acquired intangible assets are initially recorded at fair value and subsequently amortized over their useful lives using the straight-line method, which reflects the pattern of benefit, and assumes no residual value. Intangible assets with definite lives are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. The remaining estimated useful lives of definite-lived intangible assets are routinely reviewed and, if the estimate is revised, the remaining unamortized balance is amortized over the revised estimated useful life. Goodwill Goodwill represents the excess of purchase price over fair value of the net assets acquired in an acquisition. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Beginning in 2023, the Company assesses goodwill for impairment as of October 1 annually or more frequently upon an indicator of impairment. Prior to 2023, the Company assessed goodwill for impairment as of December 31 annually or more frequently upon an indicator of impairment. The change to an October 1 annual goodwill impairment assessment date was made to ensure the completion of the Company’s assessment prior to the end of its annual reporting period, thereby aligning impairment testing procedures with its year-end financial reporting. Goodwill is tested for impairment at the reporting unit level using a fair value approach. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, based on a review of qualitative factors, it is more likely than not that the fair value of a reporting unit is less than its carrying value the Company compares the fair value of a reporting unit with its carrying amount. The Company determines the fair value of a reporting unit by estimating the present value of expected future cash flows, discounted by the applicable discount rate. If the carrying value exceeds the fair value, the Company measures the amount of impairment loss, if any, by comparing the implied fair value of the reporting unit goodwill with its carrying amount. No impairment charges have been required. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds its estimated undiscounted net cash flow, excluding interest, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds its fair value. Investments accounted for under the equity method are recorded based upon the amount of the Company’s investment and are adjusted each period for the Company’s share of the investee’s income or loss. Investments are reviewed periodically for changes in circumstances or the occurrence of events that suggest an other-than-temporary event where the investment may not be recoverable. Cost Method Investments The Company holds equity securities without a readily determinable fair value, which are only adjusted for observable price changes in orderly transactions for the same or similar equity securities or any impairment. As of December 31, 2023 and 2022, the Company had $5.0 million and $1.0 million of cost method investments included in Other noncurrent assets in the Consolidated Balance Sheets, respectively. Deferred Offering Costs Deferred offering costs primarily consist of capitalized legal, accounting and other third-party costs incurred that are directly related to the Reverse Recapitalization, which has been accounted for as a reverse recapitalization. These costs were recorded to Stockholders’ deficit as a reduction of Additional paid-in capital generated upon the completion of the Reverse Recapitalization. As of December 31, 2023, the Company recorded $18.0 million to Stockholders’ deficit in the Consolidated Balance Sheets. For the year ended December 31, 2023, the Company recorded $0.5 million to Selling, general and administrative expense in the Consolidated Statements of Operations. As of December 31, 2022, the Company recorded $5.8 million of deferred offering costs in the Consolidated Balance Sheets. Debt Issuance Costs Debt issuance costs consist of expenditures associated with obtaining debt financing, principally legal and bank commitment fees. Such costs are deferred and amortized over the term of the related credit arrangements using a method that approximates the effective interest method. Debt issuance costs are included in the Consolidated Balance Sheets as a direct deduction from the carrying amount of long-term debt and are included in Interest expense in the Consolidated Statements of Operations. The payment of debt issuance costs is recorded under financing activities in the Consolidated Statements of Cash Flows. Fair Value of Financial Instruments The Company follows guidance in ASC 820, Fair Value Measurement (“ASC 820”), where fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are determined within a framework that establishes a three-tier hierarchy which maximizes the use of observable market data and minimizes the use of unobservable inputs to establish a classification of fair value measurements for disclosure purposes. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the information available. ASC 820 classifies the inputs used to measure these fair values into the following hierarchy: Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs and quoted prices in active markets for similar assets and liabilities. Level 3 — Unobservable inputs and models that are supported by little or no market activity. In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety has been determined based on the lowest level of input that is significant to the fair value measurement. Revenue Recognition The Company charges daily and hourly rates depending upon the type of firefighting service rendered and under which contract the services are performed. These services are primarily split into flight revenue and standby revenue. Flight revenue is earned primarily at an hourly rate when the engines of the aircraft are started and stopped upon request of the customer, tracked via flight logs for Super Scoopers or a Hobbs meter for other aircraft. Standby revenue is earned primarily as a daily rate when aircraft are available for use at a fire base, awaiting request from the customer for flight deployment. The Company enters into short, medium and long-term contracts with customers, primarily with government agencies during the firefighting season, to deploy aerial fire management assets. Revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied and payment is typically due within 30 days of invoicing. Invoicing occurs as the services are rendered and includes the use of the aircraft, pilot and field maintenance personnel to support the contract. Contracts are based on either a Call-When-Needed (“CWN”) or Exclusive Use (“EU”) basis. Rates established are generally more competitive based on the security of the revenue from the contract (i.e., an EU versus only on an as-needed basis in CWN). These rates are delineated by the type of service, generally flight time or time available for deployment. Once an aircraft is deployed on a contract the fees are earned at these rates, the aircraft cannot be obligated to another customer. Contracts have no financing components and consideration is at pre-determined rates. No variable considerations are constrained within the contracts. The transaction prices are allocated on the service performed and tracked real-time by each operator in a duty log. On at least a monthly basis, the services performed and rates are validated by each customer. Acceptance by the customer is evidenced by their funded task order or accepted invoice. The Company has not incurred incremental costs for obtaining contracts with customers. In addition, the Company evaluates whether or not it should capitalize the costs of fulfilling a contract. Such costs would be capitalized when they are not within the scope of other standards and: (1) are directly related to a contract; (2) generate or enhance resources that will be used to satisfy performance obligations; and (3) are expected to be recovered. The Company has elected to use the practical expedient detailed in ASC 340-40, Other Assets and Deferred Costs-Contracts with Customers , to expense any costs to fulfill a contract as they are incurred when the amortization period would be one year or less. Contract assets are classified as a receivable when the reporting entity’s right to consideration is unconditional, which is when payment is due only upon the passage of time. As the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional, contracts do not typically give rise to contract assets. Contract liabilities are recorded when cash payments are received or due in advance of performance. Payment terms vary by customer and type of revenue contract. The Company generally expects that the period of time between payment and transfer of promised goods or services will be less than one year. In such instances, the Company has elected the practical expedient to not evaluate whether a significant financing component exists. As permitted under the practical expedient available under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, and (ii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. Other revenue consists of leasing revenues for facilities as well as external repair work performed on customer aircraft. Revenue Disaggregation The following table presents the disaggregation of revenue by service: For the Years Ended December 31, $s in thousands 2023 2022 Fire suppression $ 56,022 $ 38,845 Aerial surveillance 9,730 7,216 Other services 956 327 Total revenues $ 66,708 $ 46,388 The following table presents the disaggregation of revenue by type: For the Years Ended December 31, $s in thousands 2023 2022 Flight revenue $ 34,171 $ 25,105 Standby revenue 30,650 20,772 Other revenue 1,887 511 Total revenues $ 66,708 $ 46,388 The following table presents the disaggregation of revenue by geographic area: For the Years Ended December 31, $s in thousands 2023 2022 United States $ 49,534 $ 46,388 Canada 17,174 — Total revenues $ 66,708 $ 46,388 Concentration Risk During the year ended December 31, 2023, the Company had three customers who individually accounted for 65%, 12%, and 11% of total revenues and two customers accounted for 39% and 34% of accounts receivable. During the year ended December 31, 2022, the Company had one customer who individually accounted for 95% of total revenues and one customer who individually accounted for 62% of accounts receivable. Income Taxes For periods prior to the Business Combination, Bridger Aerospace Group Holdings, LLC is a partnership for federal income tax purposes. Consequently, federal income taxes are not payable or provided for by Legacy Bridger. Members are taxed individually on their pro rata ownership share of the Legacy Bridger’s earnings. Legacy Bridger’s net income or loss is allocated among the members in accordance with the Company’s operating agreement. Subsequent to the Business Combination, Bridger Aerospace Group Holdings, Inc. became the successor of Legacy Bridger as discussed in “ Note 1 – Organization and Basis of Presentation .” Bridger is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to net taxable income or loss and any related tax credits of the Company. Bridger is also subject to taxes in foreign jurisdictions in which it operates. The Company provides for income taxes and the related accounts under the asset and liability method. Income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. The Company is subject to income taxes predominantly in the U.S. These tax laws are often complex and may be subject to different interpretations. Deferred income taxes arise from temporary differences between the financial statement carrying amount and the tax basis of assets and liabilities and are measured using the enacted tax rates expected to be in effect during the year in which the basis difference reverses. In evaluating the ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence. If based upon all available positive and negative evidence, it is more likely than not that the deferred tax assets will not be realized, a valuation allowance is established. The valuation allowance may be reversed in a subsequent reporting period if Bridger determines that it is more likely than not that all or part of the deferred tax asset will become realizable. Segment Reporting Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The Company manages its operations as a single segment for purposes of assessing performance, making operating decisions and allocating resources. This one operating and reporting segment primarily focuses on aerial firefighting. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Depository Insurance Coverage of $250,000. During the years ended December 31, 2023 and 2022, the Company did not experience losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Hedging Transactions and Derivative Financial Instruments The Company is directly and indirectly affected by changes in certain market conditions. These changes in market conditions may adversely impact the Company’s financial performance and are referred to as “market risks.” The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of certain market risks. The Company manages interest rate risk through the use of derivative instruments, such as swap agreements. A swap agreement is a contract between two parties to exchange cash flows based on specified underlying notional amounts, assets and/or indices. The Company does not enter into derivative financial instruments for trading purposes. The accounting for gains and losses that result from changes in the fair values of derivative instruments depends on whether the derivatives have been designated and qualify as hedging instruments and the type of hedging relationships. The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in Accumulated other comprehensive income and are reclassified into the line item in the Consolidated Statements of Comprehensive Loss in which the hedged items are recorded in the same period the hedged items affect earnings. The Company formally assesses whether the financial instruments used in hedging transactions are effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized into earnings. The fair value is based |
