Ameresco Inc

1. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company,” “Ameresco,” “we,” “our,” or “us”) are unaudited, according to certain rules and regulations of the Securities and Exchange Commission, and include, in our opinion, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated.

The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of results which may be expected for the full year. The December 31, 2023 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2023, included in our annual report on Form 10-K(“2023 Form 10-K”) filed with the Securities and Exchange Commission on February 29, 2024 as amended on March 11, 2024.

Reclassification and Rounding

Certain prior period amounts were reclassified to conform to the presentation in the current period. We round amounts in the condensed consolidated financial statements to thousands and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.

Significant Risks and Uncertainties

Global factors have continued to result in global supply chain disruptions and inflationary pressures.

We have considered the impact of general global economic conditions on the assumptions and estimates used, which may change in response to this evolving situation. Results of future operations and liquidity could be adversely impacted by a number of factors including supply chain disruptions, varying levels of inflation, payments of outstanding receivable amounts beyond normal payment terms, workforce disruptions, and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, we cannot reasonably estimate the extent to which macroeconomic conditions may impact our financial condition, liquidity, or results of operations in the foreseeable future. The ultimate impact of the pandemic and general global economic conditions on our business is highly uncertain and will depend on future developments, and such impacts could exist for an extended period of time, even after the pandemic subsides.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our accounting policies are set forth in Note 2 to the consolidated financial statements contained in our 2023 Form 10-K. We have included certain updates to those policies below.

Accounts Receivable and Allowance for Credit Losses

Changes in the allowance for credit losses are as follows:

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consist primarily of other receivables, deferred project costs, and other short-term prepaid expenditures that will be expensed within one year.

Prepaid expenses and other current assets comprised of the following:

Recent Accounting Pronouncements

Business Combinations— Joint Venture Formations

In August 2023, the FASB issued ASU 2023-05, Business Combinations— Joint Venture Formations (Subtopic 805-60) Recognition and Initial Measurement, which addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture’s separate financial statements. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, which updates the disclosure or presentation requirements for a variety of topics in the codification. ASU 2023-06 is effective from the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K, with early adoption prohibited. We will monitor the removal of the requirements from the current regulations and adopt the related amendments, but we do not anticipate this new guidance will have a material impact on our condensed consolidated financial statements as we are currently subject to SEC requirements.

Segment Reporting (Topic 820) - Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 820) - Improvements to Reportable Segment Disclosures, which improves reportable segment disclosures by requiring enhanced disclosures for significant segment expenses and other segment items. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

Income Taxes (Topic 740) - Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the income tax disclosures, including disaggregation of information in the rate reconciliation table and disaggregated information related to income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

Compensation—Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards

In March 2024, the FASB issued ASU 2024-01, Compensation—Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards, to clarify how to determine if a profits interest or similar award is within the scope of ASC 718 or is not a share-based payment arrangement and is within the scope of other guidance. ASU 2024-01 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

Codification Improvements—Amendments to Remove References to the Concepts Statements

In March 2024, the FASB issued ASU 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements, to remove references to various FASB Concepts Statements based on suggestions received from stakeholders on the Accounting Standards Codification and other incremental improvements to GAAP. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

3. REVENUE FROM CONTRACTS WITH CUSTOMERS

Disaggregation of Revenue

Our reportable segments for the three and six months ended June 30, 2024 were North America Regions, U.S. Federal, Europe, Alternative Fuels and All Other. On January 1, 2024, we changed the structure of our internal organization, and our U.S. Regions and Canada are now included in North America Regions. Additionally, our Asset Sustainability Group was formerly included in Canada, but is now included in “All Other”. As a result, previously reported amounts have been reclassified for comparative purposes.

The following table presents our revenue disaggregated by line of business and reportable segment for the three months ended June 30, 2024:

The following table presents our revenue disaggregated by line of business and reportable segment for the three months ended June 30, 2023:

The following table presents our revenue disaggregated by line of business and reportable segment for the six months ended June 30, 2024:

The following table presents our revenue disaggregated by line of business and reportable segment for the six months ended June 30, 2023:

The following table presents information related to our revenue recognized over time:

The remainder of our revenue is for products and services transferred at a point in time, at which point revenue is recognized.

We attribute revenues to customers based on the location of the customer. The following table presents information related to our revenues by geographic area:

Contract Balances

The following tables provide information about receivables, contract assets and contract liabilities from contracts with customers:

The increase in contract assets for the six months ended June 30, 2024 was primarily due to revenue recognized of $490,125 offset by billings of $494,441. Contract assets also increased due to reclassifications, primarily from contract liabilities as a result of timing of customer payments. The increase in contract liabilities was primarily driven by the receipt of advance payments from customers, and related billings, as well as reclassifications from contract assets as a result of timing of customer payments. The advance payments and reclassifications exceeded the recognition of revenue as performance obligations were satisfied. For the six months ended June 30, 2024, we recognized revenue of $148,279 and billed $153,688 to customers that had balances which were included in contract liabilities at December 31, 2023.

The decrease in contract assets for the six months ended June 30, 2023 was primarily due to billings of $436,030 offset by revenue recognized of $413,181. Contract assets are also affected by reclassifications, primarily from contract liabilities as a result of timing of customer payments. The increase in contract liabilities was primarily driven by the receipt of advance payments from customers, and related billings, as well as reclassifications from contract assets as a result of timing of customer payments. The advance payments and reclassifications exceeded the recognition of revenue as performance obligations were satisfied. For the six months ended June 30, 2023, we recognized revenue of $73,585 and billed $80,774 to customers that had balances which were included in the beginning balance of contract liabilities.

Performance Obligations

Our remaining performance obligations (“backlog”) represent the unrecognized revenue value of our contract commitments. At June 30, 2024, we had contracted backlog of $2,836,452 of which approximately 32% is anticipated to be recognized as revenue in the next twelve months. The remaining performance obligations primarily relate to the energy efficiency and renewable energy construction projects, including long-term operations and maintenance (“O&M”) services related to these projects. The long-term services have varying initial contract terms, up to 25 years.

Project Development Costs

Project development costs of $3,164 and $3,605 were recognized in our condensed consolidated statements of income on projects that converted to customer contracts during the three months ended June 30, 2024 and 2023, respectively. Project development costs of $6,284 and $6,217 were recognized in the condensed consolidated statements of income on projects that converted to customer contracts during the six months ended June 30, 2024 and 2023, respectively.

No impairment charges in connection with our project development costs were recorded during the three or six months ended June 30, 2024 and 2023.

4. BUSINESS ACQUISITIONS AND RELATED TRANSACTIONS

We account for acquisitions using the acquisition method in accordance with ASC 805, Business Combinations. The purchase price for each acquisition is allocated to the assets based on their estimated fair values at the date of acquisition. The excess purchase price over the estimated fair value of the net assets acquired, which is calculated using level 3 inputs per the fair value hierarchy as defined in Note 11, is recorded as goodwill. Intangible assets, if identified, are also recorded. See Note 5 for additional information.

Enerqos Energy Solutions S.r.l. (“Enerqos”)

On February 24, 2023, we signed a definitive purchase and sale agreement to acquire Enerqos, a renewable energy and energy efficiency company headquartered in Milan, Italy. The acquisition closed on March 30, 2023 and the total purchase consideration was $13,445, of which $9,535 has been paid. There isno contingent consideration related to this acquisition. Cash acquired was $353, debt assumed was $3,951, and a deferred tax liability, net of $931 was recorded. In accordance with the SEC’s Regulation S-X and GAAP, we evaluated and determined that Enerqos is not deemed to be a significant subsidiary, therefore, we are not presenting the pro-forma effects of this acquisition on our operations.

The estimated goodwill of $6,855 from the Enerqos acquisition consists largely of expected benefits, including the combined entities experience and the acquired workforce. This goodwill is not deductible for income tax purposes. The estimated fair value of tangible and intangible assets acquired, and liabilities assumed are based on management's estimates and assumptions that are preliminary and subject to adjustments. Any adjustments made beyond the measurement period will be included in our condensed consolidated statements of income.

The results of the acquisition since the date of the acquisition have been included in our operations as presented in the accompanying condensed consolidated statements of income, condensed consolidated statements of comprehensive income and condensed consolidated statements of cash flows. For the three months ended June 30, 2024, we recognized $8,855 of revenue and $989 of net loss relating to Enerqos and for the six months ended June 30, 2024, we recognized $13,033 of revenue and $1,729 of net loss relating to Enerqos. For the three and six months ended June 30, 2023, we recognized $13,041 of revenue and $182 of net income relating to Enerqos.

A summary of the cumulative consideration paid and allocation of the purchase price for the Enerqos acquisition are presented in the table below:

5. GOODWILL AND INTANGIBLE ASSETS, NET

Due to the change in the structure of our internal organization, a portion of our goodwill was allocated totwo new reporting units based on their relative fair values as of January 1, 2024. See Note 3 for additional information about the organizational changes. The changes in the carrying value of goodwill balances by reportable segment were as follows:

Definite-lived intangible assets, net consisted of the following:

The table below sets forth amortization expense:

6. ENERGY ASSETS, NET

Energy assets, net consisted of the following:

August 2023 Purchase and Sale Agreement

On August 4, 2023, we entered into a purchase and sale agreement to acquire an energy asset project and to acquire 100% of the stock of Bright Canyon Energy Corporation (“BCE”) in a two-phased transaction. Phase 1, the purchase of the energy asset project, closed on August 4, 2023 and did not constitute a business in accordance with ASC 805-50, Business Combinations.

The purchase price for phase 1 was $87,964, of which $5,000 was paid in cash, $46,694 was financed through a seller’s note, and we assumed a construction loan on the energy asset project for $36,270. We also acquired cash of $11,206. During the year ended December 31, 2023, we paid $18,400 in principal on the sellers note. In January 2024, the purchase price was increased by $1,147 and we paid off the seller’s note in the amount of $29,441. We also assumed a land lease for the energy asset project.

On December 28, 2023, we executed an amended and restated purchase and sale agreement, which primarily revised the timing of payments on phase 2. In the second phase, which closed on January 12, 2024, we acquired BCE, including its interest in a consolidated joint venture and its interests in project subsidiaries developing or with rights to develop solar, battery, and microgrid assets for an adjusted purchase price of $47,956, of which $9,839 was paid in cash and $32,500 was financed through a seller’s note. The remaining balance due of $4,011 is included in accrued expenses and other current liabilities at June 30, 2024. We also assumed four land leases for the energy asset projects.

See Note 8 for additional information about the BCE-related loans, Note 7 for information on the leases and Note 10 for potential additional commitments.

Phase 2, the purchase of the energy asset projects did not constitute a business in accordance with ASC 805-50, Business Combinations.

Transfer of Investment Tax Credits

On June 27, 2024 we sold investment tax credits (“ITC”) onfour energy assets to a third party at a fair value of $23,667 which was received during the three months ended June 30, 2024. We also received a deposit of $239 for the sale of ITC onfour additional energy assets at a total fair value of $23,867. The benefit from the sale of the ITC will be recognized in profit or loss as a reduction to depreciation expense over the life of the energy assets.

Depreciation and Amortization Expense

The following table sets forth our depreciation and amortization expense on energy assets, net of deferred grant and ITC amortization:

Capitalized Interest

The following table presents the interest costs relating to construction financing during the period of construction, which were capitalized as part of energy assets, net:

The costs related to our leases were as follows:

Supplemental cash flow information related to our leases was as follows:

The table below sets forth our estimated minimum future lease obligations under our leases:

We have future lease commitments for office and ground leases which do not yet meet the criteria for recording a ROU asset or ROU liability. The net present value of these commitments total $18,859 as of June 30, 2024 and relate to lease payments to be made over 5 to 25 years. This includes a ground lease totaling $10,500 that we are in process of modifying such that the criteria to record a ROU asset and ROU liability may not be met.

Non-monetary Lease Transactions

We havesix lease liabilities consisting of obligations that will be settled with non-monetary consideration. The lease liabilities relating to non-monetary consideration were recorded during the six months ended June 30, 2024 based on the fair market value of the project services or back up power expected to be provided, which approximate the cash payments.

Sale-leasebacks

These facilities are accounted for as failed sale leasebacks and are classified as long-term financing facilities.

August 2018 Master Sale-leaseback

We enter into amendments to our August 2018 master lease and participation agreement from to time to time, which may extend the maturity date, increase the availability, or modify other covenants.

We sold and leased backtwo energy assets for $22,116 in cash proceeds under this facility during the six months ended June 30, 2024. As of June 30, 2024, we have available funds remaining under this lending commitment.

Net gains from amortization expense recognized in cost of revenues relating to deferred gains and losses in connection with our sale-leaseback agreements were $57 and $114 for the three and six months ended June 30, 2024 and 2023, respectively.

December 2020 Master Sale-leaseback

We enter into amendments to our December 2020 master lease and participation agreement from to time to time, which may extend the maturity date, increase the availability, or modify other covenants. We were in default under this agreement as we had failed to satisfy the insurance requirements and historical coverage ratio under this agreement. On May 3, 2024, we received a waiver on this default.

8. DEBT AND FINANCING LEASE LIABILITIES

Our debt and financing lease liabilities are comprised of the following:

Senior Secured Credit Facility

On April 10, 2024, we entered into amendment number five to the fifth amended and restated senior secured credit facility to extend the maturity date of the delayed draw term loan A (“DDTLA”) from March 4, 2025 to August 15, 2024. The amendment also included the following modifications:

•principal installments on the DDTLA of $5,000 at closing of the amendment and $7,500 each on or before May 15, 2024, June 15, 2024, and July 15, 2024, with the balance of $7,500 due on August 15, 2024,

•the date by which we shall use commercially reasonable efforts to raise $100,000 in equity or subordinated debt financing was changed from April 15, 2024 to May 15, 2024.

On June 28, 2024, we entered into amendment number six to the fifth amended and restated senior secured credit facility to modify certain of the covenants and other terms to permit us to enter into the second lien credit agreement (as defined below) and to incur indebtedness and make certain other conforming changes in connection with our entry into the second lien credit agreement.

June 2024, Second Lien Term Loan, due June 28, 2029

On June 28, 2024, we entered into a second lien credit agreement which provided a term loan in a principal amount of $100,000 with a maturity date of June 28, 2029. The term loan bears an interest rate of SOFR (5.353% at June 30, 2024), plus an applicable margin of 5.875% per annum. Interest is payable quarterly and unpaid interest and principal is due in the aggregate on June 28, 2029. At closing, we incurred $3,623 in lenders fees and debt issuance costs. Proceeds from this term loan in the amount of $82,105 and $15,000 were used to pay towards our revolving credit facility and the outstanding portion of the DDTLA, respectively, under our senior secured credit facility at closing.

April 2024, Term Notes, due June 30, 2042

On April 5, 2024, an omnibus amendment and reaffirmation agreement was executed with reference to the note purchase and private shelf agreement, dated as of July 27, 2021, andtwo new series B notes (first lien and second lien) were authorized in the amounts of $92,512 and $12,657, with a maturity date of June 30, 2042. Gross proceeds from the initial issuance on April 5, 2024 were $83,282 and $12,292 with the remainder to be issued upon achieving certain permitting-related and other administrative conditions. The notes bear interest at fixed rates of 6.20% and 8.00%, respectively, per annum and the interest is payable quarterly commencing September 30, 2024. At closing, we incurred $1,296 in lenders fees and debt issuance costs. Proceeds from these notes in the amount of $86,462 were used to pay a portion of the August 2023 construction credit facility. In connection with these notes, we recordedtwo derivative instruments for make-whole provisions with initial values of $8,733 and $647, respectively, which were recorded as debt discount.

October 2022, Financing Facility,6.70%, due August 31, 2039

During the six months ended June 30, 2024, we drew down an additional $38,280 and at June 30, 2024, $373,852 was outstanding under this facility, net of unamortized debt discount and issuance costs.

April 2023, Construction Credit Facility,6.81%, due August 16, 2024

We were in default on this credit facility due to administrative errors, for which a waiver was received on June 27, 2024.

Debt Instruments - Energy Asset Acquisitions

As discussed in Note 6, on August 4, 2023, we acquired an energy asset project. The purchase price for phase 1 was $87,964, of which $5,000 was paid in cash, $46,694 was financed through a seller’s note, and we assumed a construction loan on the energy asset project for $36,270. During the year ended December 31, 2023, we paid $18,400 in principal on the seller’s note. In January 2024, the purchase price was increased by $1,147 and we paid off the seller’s note in the amount of $29,441.

On February 26, 2024, the construction loan in the amount of $36,270 was converted into a term loan and has a maturity date of April 2030. The term loan bears a base SOFR interest rate of 5.35% at June 30, 2024, and an applicable margin of 1.635% per annum for four years after the term conversion date and 1.76% per annum for the following two years. The interest and principal are paid quarterly commencing on June 30, 2024. We failed to achieve the final conditions required to convert the term loan on or prior to June 30, 2024, therefore, the $35,696 outstanding balance was classified as current debt at June 30, 2024. We are negotiating a waiver with the lender that will become effective when the final conditions are met, which is expected to be during the quarter ending September 30, 2024.

In the second phase, which closed on January 12, 2024, we acquired BCE, including its interest in a consolidated joint venture and its interests in project subsidiaries developing or with rights to develop solar, battery, and microgrid assets for an adjusted purchase price of $47,956, of which $9,839 was paid in cash and $32,500 was financed through a seller’s note. The note bore interest at a fixed rate of 5.0% per annum and the principal and interest was due in August 2024. The note was amended on August 2, 2024 to provide that it be paid in four installments through December 16, 2024 and bears interest at a rate of 5.0% per annum through August 2, 2024 and a rate of 9.0% per annum thereafter.

9. INCOME TAXES

We recorded aprovisionfor income taxes of $0 and $5 for thethree months ended June 30, 2024 and 2023, respectively.

We recorded aprovisionfor income taxes of $0 andbenefit of $498 for thesix months ended June 30, 2024 and 2023, respectively.

The effective tax rate was 0.0% for thethree months ended June 30, 2024, compared to the effective tax rate of 0.1% for thethree months ended June 30, 2023. The principal reasons for the higher effective rate for 2024 is due to the effects of a smaller Section 179D Energy Efficient Building deduction, offset by higher investment tax credits from solar, and storage plants placed into service or are forecasted to be placed into service during 2024, state taxes, and foreign earnings.

The effective tax rate was 0.0% for thesix months ended June 30, 2024, compared to a benefit of 5.3% for thesix months ended June 30, 2023. The principal reasons for the higher effective rate for 2024 is due to the effects of a smaller Section 179D Energy

Efficient Building deduction, offset by higher investment tax credits from solar, and storage plants placed into service or are forecasted to be placed into service during 2024, state taxes, and foreign earnings.

10. COMMITMENTS AND CONTINGENCIES

From time to time, we issue letters of credit and performance bonds with our third-party lenders, to provide collateral.

Legal Proceedings

We are involved in a variety of other claims and other legal proceedings generally incidental to our normal business activities. When we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings and, if material, disclosed below. When only a range of amounts is reasonably estimable and no amount within the range is more likely than another, the low end of the range is recorded. While the ultimate amount of liability incurred in any of these matters is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these claims and legal proceedings cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. For any other claims where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established, but the matter, if potentially material, is disclosed below. We routinely review relevant information with respect to our matters and update our accruals, disclosures and estimates of reasonably possible loss based on such reviews. While the outcome of any of these matters cannot be accurately predicted, we do not believe the ultimate resolution of any of these existing matters would have a material adverse effect on our financial condition or results of operations.

In October 2021, we entered into a contract with SCE to design and build three grid scale battery energy storage system (“BESS”) at three sites near existing substation parcels throughout SCE’s service territory in California with an aggregate capacity of 537.5 megawatt (“MW”) (“the SCE Agreement”). As previously disclosed, due to supply chain delays, weather, and other events, we were unable to complete the projects by August 1, 2022 (the “Guaranteed Completion Date”) and made related force majeure claims. In late 2022, SCE also instructed us to adjust the completion of the sites into 2023. Under the SCE Agreement, a failure to reach the Guaranteed Completion Date could, under certain circumstances, result in liquidated damages up to a maximum amount of $89 million being applied. We have been working with SCE to analyze the applicability and scope of force majeure relief based on our force majeure claims and we expect that SCE will withhold liquidated damages for at least two of the three projects. Our view is that liquidated damages should not be applied. It is at least reasonably possible we may incur an obligation to pay liquidated damages up to the maximum amount.

Commitments as a Result of Acquisitions

In December 2021, we completed our acquisition of Plug Smart which provided for an earn-out based on future EBITDA targets beginning with EBITDA performance for the month of December 2021 and each fiscal year thereafter, over afive-year period through December 31, 2026. The maximum cumulative earn-out is $5,000 and we evaluated financial forecasts of the acquired business and concluded that the fair value of this earn-out after payments of $3,040 was approximately $1,465 at December 31, 2023 and June 30, 2024, and is included in accrued expenses and other current liabilities, and other liabilities on the condensed consolidated balance sheets. See Note 11 for additional information.

The August 4, 2023 purchase and sale agreement with BCE includes a potential earn-out that could be earned if the projects achieve specified value thresholds in certain phase 2 projects, each of which is very early in development, or if milestones are achieved on other future projects that are not yet started. The total earn-out is limited to $40,000 over aseven-year period beginning on January 12, 2024. We will record a liability for the phase 2 earn-out payments when the amounts are probable and estimable. As of June 30, 2024, none of the earn-out amounts are considered probable and estimable.

11. FAIR VALUE MEASUREMENT

We recognize our financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs that may be used to measure fair value are as follows:

Level 1: Inputs are based on unadjusted quoted prices for identical instruments traded in active markets.

Level 2: Inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3: Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques.
