Summary of Significant Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies (a) Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and are presented in Indian rupees (“INR”), unless otherwise stated. The consolidated financial statements include the accounts of APGL and companies which are directly or indirectly controlled by APGL. All intercompany accounts and transactions have been eliminated upon consolidation. Certain balances relating to prior years have been reclassified, wherever required, to conform to the current year presentation. All share and per share amounts presented in the consolidated financial statements have been adjusted to reflect the 16-for-1 stock split of the Company’s equity shares that was effective on October 6, 2016. (b) Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs, expenses and comprehensive loss/ gain that are reported and disclosed in the consolidated financial statements and accompanying notes. These estimates are based on management’s best knowledge of current events, historical experience, actions the Company may undertake in the future and on various other assumptions that are believed to be prudent and reasonable under the circumstances. Significant estimates and assumptions are used for, but not limited to impairment of and useful lives of property, plant and equipment, determination of asset retirement obligations, valuation of derivative instruments, hedge accounting, lease liabilities, right to use asset, allowances for doubtful accounts based on payment history, credit rating, valuation of share-based compensation, income taxes, energy kilowatts expected to be generated over the useful life of the solar power plant, estimated transaction price, including variable consideration, of the Company’s revenue contracts, impairment of other assets, impairment of net assets classified as held for sale and other contingencies and commitments. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates, and such differences may be material to the consolidated financial statements. Estimation uncertainty relating to COVID-19 pandemic In evaluating the recoverability of accounts receivable including unbilled revenue, contract assets, long-lived assets and investments, the Company has considered, at the date of approval of these consolidated financial statements, internal and external information in the preparation of the consolidated financial statements including the economic outlook. The Company has performed sensitivity analysis on the assumptions used to assess the recoverability of these assets and based on current estimates, expects the carrying amount of these assets will be recovered. Based on the current collection experience the Company has not seen a material impact on accounts receivables collections due to COVID-19. The impact of COVID-19 may be different from that estimated on preparation of these consolidated financial statements and the Company will continue to closely monitor any material changes to future economic conditions. See also Note 2 (ab) - Impact of COVID-19 Pandemic. Principles of Consolidation The accompanying consolidated financial statements include the accounts of APGL, its subsidiaries, and variable interest entities (“VIE”), where the Company has determined it is the primary beneficiary and are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company uses the equity method to account for its investments in entities where it exercises significant influence over operating and financial policies but does not retain control under either the voting interest model (generally 20% to 50% ownership interest) or the variable interest model. In 2020, the Company entered into a joint venture agreement with a third party to establish a manufacturing facility to supply solar PV modules as a part of execution of manufacturing linked tender. Further during the current year, the Company has entered into an agreement with other party and made an initial investment in equity shares of its identified subsidiary as part of execution of contract, as further described in Note 10—Investments, and these investment are accounted for using the equity method. The Company has eliminated all intercompany accounts and transactions. (c) Foreign currency translation and transactions The functional currency of APGL is the United States Dollar (“US$”) and reporting currency is Indian rupees (“INR”). The Company’s subsidiaries with operations in India use INR as the functional currency and the subsidiaries in the United States and Mauritius use US$ as the functional currency. The financial statements of APGL and its subsidiaries, other than subsidiaries with a functional currency of INR, are translated into INR using the exchange rate as of the balance sheet date for assets and liabilities, historical exchange rates for equity transactions and average exchange rate for the year for income and expense items. Translation gains and losses are recorded in accumulated other comprehensive income or expenses as a component of shareholders’ equity. Transactions in currencies other than the functional currency are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the functional currency are translated into the functional currency using the exchange rate at the balance sheet date. All gains and losses arising from foreign currency transactions are recorded in the determination of net income or loss/(gain) during the year in which they occur. Revenue, expense and cash flow items are translated using the average exchange rates for the respective period. The resulting gains and losses from such translations are excluded from the determination of earnings and are recognized instead in accumulated other comprehensive loss/ (gain), which is a separate component of shareholders’ equity. Realized and unrealized foreign currency transaction gains and losses, other than those hedged by the Company, arising from exchange rate fluctuations on balances denominated in currencies other than the functional currency of an entity, such as those resulting from the Company’s borrowings in other than functional currency is included in Loss/(gain) on foreign currency exchange, net in the consolidated statements of operations. (d) Convenience translation Translation of balances in the consolidated balance sheets and the consolidated statements of operations, comprehensive loss, shareholders’ equity and cash flows from INR into US$, as of and for the year ended March 31, 2022 are solely for the convenience of the readers and were calculated at the rate of US$1.00 = INR 75.87 , the noon buying rate in New York City for cable transfers in non U.S. currencies, as certified for customs purposes by the Federal Reserve Bank of New York on March 31, 2022 . No representation is made that the INR amounts could have been, or could be, converted, realized or settled into US$ at that rate on March 31, 2022, or at any other rate. (e) Cash and cash equivalents Cash and cash equivalents include demand deposits with banks, term deposits and all other highly liquid investments purchased with an original maturity of three months or less at the date of acquisition and that are readily convertible to cash. The Company has classified term deposits totaling INR 9,936 million and INR 10,482 million (US$138.2 million) as of March 31, 2021 and 2022, respectively, as cash and cash equivalents, because the Company has the ability to redeem these deposits at any time subject to an immaterial interest rate forfeiture. All term deposits are readily convertible into known amount of cash with no more than one day notice. (f) Restricted cash Restricted cash consists of cash balances restricted as to withdrawal or usage and relates to cash used to collateralize bank letters of credit supporting the purchase of equipment for solar power plants, bank guarantees issued in relation to the construction of the solar power plants within the timelines stipulated in PPAs and for certain debt service reserves required under the Company’s loan agreements. Restricted cash is classified into current and non-current portions based on the term of the deposit and the expiration date of the underlying restriction. The following table presents the components of cash and cash equivalents and restricted cash included in the consolidated balance sheets that sums to the total of such amounts in the Consolidated Statements of Cash Flows: March 31, 2020 2021 2022 2022 (INR) (INR) (INR) (US$) (In million) Current Assets Cash and cash equivalents 9,792 11,107 18,796 247.7 Restricted cash 4,877 4,881 3,784 49.9 Non-Current Assets Restricted cash 848 170 726 9.6 Cash and cash equivalents and restricted cash 15,517 16,158 23,306 307.2 (g) Investments The Company determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation at each balance sheet date. The investment securities held by the Company during the periods presented in the accompanying consolidated financial statements are classified as available-for-sale (short-term investments), consisting of liquid mutual funds units and held-to-maturity investments (long-term investments), consisting of Notes of the Bank of Mauritius. The Company accounts for its investments in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 320, Accounting for Certain Investments in Debt and Equity Securities Securities that the Company has positive intent and ability to hold until maturity are classified as held-to-maturity securities and stated at amortized cost. As of March 31, 2021, and March 31, 2022, amortized cost of held-to-maturity investments was INR 7 million and INR 6 million (US$0.1 million), respectively. The maturity date of the investment is January 31, 2023. Realized gains and losses and a decline in value judged to be other than temporary on these investments are included in the consolidated statements of operations. The cost of securities sold or disposed is determined on the First in First Out (“FIFO”) method. Investment in equity investee The Company holds equity investments where it does not have a controlling financial interest but has the ability to exercise significant influence over the operating and financial policies of the investee. These investments are accounted for under the equity method of accounting wherein the Company records its proportionate share of the investee’s income or loss in its consolidated financial statements, as further described in Note 10—Investments (h) Accounts receivable, net The Company adopted “ASC Topic 326” Financial Instruments — Credit Losses, effective April 1, 2020 using the modified retrospective transition approach. The new guidance requires the measurement and recognition of expected credit losses (ECL) for financial assets held at amortized cost and replaces the existing incurred loss impairment model with an expected loss model using the forward-looking information to calculate credit loss estimates. The new model requires consideration of a broader range of relevant information, such as offtake ratings historical loss experience, current economic conditions, and reasonable and supportable forecasts. The impact of adoption of this guidance did not have a material effect on the Company’s financial statements. Credit Risk Credit risk is the risk that counterparty will not meet its obligations under a financial instrument which consists principally of accounts receivables, cash and cash equivalents and restricted cash, leading to a financial loss. Customer credit risk is managed using the Company’s established policy, procedures and control relating to customer credit risk management. Outstanding accounts receivables are regularly monitored. The Company’s accounts receivables are generated by selling energy to customers and are reported net of any allowance for uncollectible accounts. The allowance for credit losses is based on various factors, including the length of time receivables are past due, significant one-time events, the financial health of customers and historical experience. The allowance for credit losses at March 31, 2021 and March 31, 2022 was INR 475 million and 285 million (US$3.8 million), respectively. Accounts receivable serve as collateral for borrowings under the Company’s working capital facility, described in Note 12. (i) Property, plant and equipment Property, plant and equipment represents the costs of completed and operational solar power plants, as well as the cost of furniture and fixtures, vehicles, office and computer equipment, leasehold improvements, freehold land and construction in progress. Construction in progress represents the accumulated cost of solar power plants that have not been placed into service at the date of the balance sheet. Construction in progress includes the cost of solar modules for which the Company has taken legal title, civil engineering, electrical and other related costs incurred during the construction of a solar power plant. Construction in progress is reclassified to property, plant and equipment when the project begins its commercial operations. Property, plant and equipment are stated at cost, less accumulated depreciation and accumulated impairment losses. Depreciation is calculated using the straight-line method over the assets’ estimated useful lives as follows: Plant and machinery (solar power plants) 25-35 years Furniture and fixtures 5 years Vehicles 5 years Office equipment 1-5 years Computers 3 years Leasehold improvements related to office facilities are depreciated over the shorter of the lease period or the estimated useful life of the improvement. Lease hold improvements on the solar power plant sites are depreciated over the shorter of the lease term or the remaining period of the PPAs undertaken with the respective customer. Freehold land is not depreciated. Construction in progress is not depreciated until it is ready to be used. Improvements to property, plant and equipment deemed to extend the useful economic life of an asset are capitalized. Maintenance and repairs that do not improve efficiency or extend the estimated economic life of an asset are expensed as incurred. Additional capacity, if any, added to property plant and equipment is depreciated over the remaining estimated useful live. Capitalized interest Interest incurred on funds borrowed to finance construction of solar power plants is capitalized until the plant is ready for its intended use. The amount of interest capitalized during the years ended March 31, 2020, 2021 and 2022 were INR 355 million, INR 333 million and INR 595 million (US$7.8 million), respectively. (j) Accounting for impairment of long-lived assets The Company periodically evaluates whether events have occurred that would require revision of the remaining useful life of property, plant and equipment and improvements, or render their carrying value not recoverable. If such circumstances arise, the Company uses an estimate of the undiscounted value of expected future operating cash flows to determine whether the long-lived assets are impaired. If the aggregate undiscounted cash flows are less than the carrying amount of the assets, the resulting impairment charge to be recorded is calculated based on the excess of the carrying value of the assets over the fair value of such assets, with the fair value determined based on an estimate of discounted future cash flows, appraisals, or other valuation techniques. Other than which relates to the planned disposal of the Company’s rooftop business, there were no (k) Leases and land use rights In February 2016, the FASB issued ASU 2016-02, Leases (“ASC Topic 842”), to increase transparency and comparability among organizations by recognizing a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months and disclosing key information about leasing transactions. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842) – Targeted Improvements, which provided an optional transition method to apply the new lease requirements through a cumulative-effect adjustment in the period of adoption. The Company adopted the guidance effective April 1, 2019 using the modified retrospective approach and elected certain practical expedients permitted under the transition guidance. The majority of the Company’s leases relate to leasehold land on which the solar power plants are constructed on and leases related to office facilities. The leasehold land related to solar power plants has a lease term ranging between 25 to 35 year which is further extendable on mutual agreement by both lessor and lessee. Where applicable, the company has the consent from the lessors to extend the leases up to 35 years. These leases have rent escalation ranging between 5% to 10%, over the tenure of the lease. All existing leases on the date of adoption of ASC Topic 842, were classified as operating leases as they were concluded at their inception under previous guidance of ASC Topic 840, as permitted by the practical expedient package elected. As the implicit rate in the lease contract is not readily determinable, the company has used its average incremental rate of borrowing of 10% for the purposes of the determination of discount rate. The weighted average remaining lease term for operating leases is 30 years. On Adoption of ASC 842, all the lease arrangements entered prior to adoption continued to be classified as operating leases. The Company has made an assessment for lease arrangements entered during the year and classified them as operating leases. The Company did not have any finance lease during any of the periods presented in the accompanying consolidated financial statements. The Company is a lessee in several non-cancellable operating leases, primarily for construction of solar power plants and for office facilities. The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date. For operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments include how the Company determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments. ASC Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. Lease payments included in the measurement of the lease liability comprise of the following: ■ Fixed payments, including in-substance fixed payments, owed over the lease term (which includes termination penalties the Company would owe if the lease term assumes Company exercise of a termination option); ■ Variable lease payments, if any, that depend on an index or rate, initially measured using the index or rate at the lease commencement date; ■ Amounts expected to be payable under a Company-provided residual value guarantee; and ■ The exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise the option. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has recognized and reported the Right of Use asset, on consolidated balance sheet by INR 4,465 million (US$58.9 million) as well as Lease Liabilities by INR 3,834 million (US$50.5 million) as at March 31, 2022 and INR 4,214 million in Right of Use asset as well as Lease Liabilities by INR 3,642 million as at March 31, 2021 respectively. During the year ended March 31, 2021 and 2022, the Company recorded lease cost of INR 502 million and INR 439 million (US$5.8 million) respectively. See Note 18 to the consolidated financial statements. ROU assets for operating leases are periodically reduced by impairment losses. The Company uses the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to be recognized. See Note 2(j). The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero Operating lease ROU assets are presented as operating lease right -of -use assets on the consolidated balance sheet. The current portion of operating lease liabilities is included in other current liabilities and the long-term portion is presented separately as operating lease liabilities on the consolidated balance sheet. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases of warehouses, office, machinery etc. that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term. The Company’s corporate office leases generally also include non-lease maintenance services (i.e. common area maintenance). The Company allocates the consideration in the contract to the lease and non-lease maintenance component based on each component’s relative standalone price. The Company determines stand-alone prices for the lease components based on the prices for which other lessors lease similar assets on a stand-alone basis. The Company determines stand-alone prices for the non-lease components (i.e. maintenance services) based on the prices that several suppliers charge for maintenance services for similar assets on a stand-alone basis. (l) Asset retirement obligations (ARO) Upon the expiration of the land lease arrangement for solar power plants located on leasehold land, the Company is required to remove the solar power plant and restore the land. The Company records the fair value of the liability for the legal obligation to retire the asset in the period in which the obligation is incurred, which is generally when the asset is constructed. When a new liability is recognized, the Company capitalizes it by increasing the carrying amount of the related long-lived asset, which results in an ARO asset being depreciated over the remaining useful life of the solar power plant. The liability is accreted and expensed to its present expected future value each period based on a credit adjusted risk free interest rate. Upon settlement of the obligation, the Company eliminates the liability and based on the actual cost to retire, may incur a gain or loss. The Company’s asset retirement obligations were INR 811 million and INR 902 million (US$11.9 million) as of March 31, 2021 and 2022, respectively. The accretion expense incurred during the years ended March 31, 2020, 2021 and 2022 was INR 36 million, INR 42 million and INR 59 million (US$0.8 million), respectively. The depreciation expense incurred during the years ended March 31, 2020, 2021 and 2022 was INR 21 million, INR 23 million and INR 14 million (US$0.2 million), respectively. During the current year, the carrying amount of the ARO liability is increased by INR 91 million (US$1.2 million) primarily due to commissioning of new projects during the year partially offset by revision in the estimated cost of retirement obligation, with a corresponding adjustment to the related long-lived asset. The movement in liability during the current year as of March 31, 2022 and comparative year is as below: 2021 (INR) 2022 (INR) 2022 (US$) (In million) Beginning balance 741 811 10.7 Addition during the year 211 157 2.1 Impact of change in estimate (183 ) (125 ) (1.7 ) Liabilities settled during the year — — — Accretion expense during the year 42 59 0.8 Ending balance 811 902 11.9 (m) Software The Company capitalizes certain internal software development cost under the provision of ASC Topic 350-40 Internal-Use Software (n) Debt financing costs Financing costs incurred in connection with obtaining construction and term financing loans are deferred and amortized over the term of the respective loan using the effective interest rate method. Amortization of debt financing costs is capitalized during construction and recorded as interest expense in the consolidated statements of operations, following commencement of commercial operations of the respective solar power plants. Amortization of debt financing costs for the years ended March 31, 2020, 2021 and 2022 was INR 709 million, INR 369 million and INR 1,107 million (US$14.6 million), including debt financing costs written off related to the debt refinancing amounting to INR 271 million, INR 30 million and INR 739 million (US$9.7 million), respectively. See Note 12. The carrying value of debt financing costs as on March 31, 2021 and 2022 was INR 1,107 million and INR 1,189 million (US$15.7 million), excluding the debt finance cost against borrowings which are reported as liabilities held for sale. See Note 12. Further, the Company had debt financing costs of INR 367 million and INR 141 million (US$1.9 million) under other assets and other current assets, as on March 31, 2021 and 2022, respectively for facilities not yet drawn. See Note 6. (o) Income taxes Income taxes are recorded under the asset and liability method, as prescribed under ASC Topic 740 Income Taxes, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company establishes valuation allowances against its deferred tax assets when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The computation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company applies a two-step approach to recognize and measure uncertainty in income taxes in accordance with ASC Topic 740. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement through March 31, 2022, the Company does not have any unrecognized tax benefits, nor has it recognized any interest or penalties. During the year ended 2019-20, the Taxation Laws (Amendment) Act, 2019 brought key changes to corporate tax rates in the Income Tax Act, 1961, which reduced the tax rate for certain subsidiaries within the group to 25.17%. Azure Power India Private Limited and several of its subsidiaries which are claiming tax benefits under section 80-IA of the Income Tax Act had decided not to opt for this lower tax benefit and have continued under the old regime for the fiscal year ended March 31, 2022, the statutory income tax rate as per the Income Tax Act, 1961 ranges between 25.17% to 34.94%, depending on the tax regime chosen by the particular subsidiary. (p) Employee benefits Defined contribution plan Eligible employees of the Company in India receive benefits from the Provident Fund, administered by the Government of India, which is a defined contribution plan. Both the employees and the Company make monthly contributions to the Provident Fund equal to a specified percentage of the eligible employees’ salary. The Company has no further funding obligation under the Provident Fund, beyond the contributions elected or required to be made thereunder. Contributions to the Provident Fund by the Company are charged to expense in the period in which services are rendered by the covered employees and amounted to INR 37 million, INR 27 million and INR 27 million (US$0.4 million) for the years ended March 31, 2020, 2021 and 2022, respectively. Defined benefit plan Employees in India are entitled to benefits under the Gratuity Act, a defined benefit post-employment plan covering eligible employees of the Company. This plan provides for a lump-sum payment to eligible employees at retirement, death, and incapacitation or on termination of employment, of an amount based on the respective employee’s salary and tenure of employment. As of March 31, 2022, this plan is unfunded. Current service costs for defined benefit plans are accrued in the period to which they relate. In accordance with ASC Topic 715, Compensation Retirement Benefit- Compensated absences The Company recognizes its liabilities for compensated absences in accordance with ASC Topic 710, Compensation-General (q) Revenue recognition Sale of power consists of solar energy sold to customers under long term Power Purchase Agreements (PPAs), which generally have a term of 25 years. The Company’s customers are generally the Government of India, power distribution companies and, to a lesser extent, commercial and industrial enterprises. Sale of power includes solar power sold through exchange. The Company recognizes revenue on PPAs when the solar power plant generates power and is supplied to the customer in accordance with the respective PPA. The company recognizes revenue each period based on the volume of solar energy supplied to the customer at the price stated in the PPA once the solar energy kilowatts are supplied and collectability is reasonably assured. The solar energy kilowatts supplied by the Company are validated by the customer prior to billing and recognition of revenue. Revenues from the recovery of safe-guard duties and goods and service tax under the change in law provision are recognized over the PPA period in the proportion of the actual sale of solar energy in kilowatts as per the terms agreed with customers or unless contractually agreed otherwise, once collectability is reasonably assured. Revenue from the sale of carbon credit emissions are recognized at the time of transfer of carbon credits to the customers, at consideration agreed under the sale agreements. The Company applies “ASC Topic 606” Revenue from Contracts with Customers, to recognize revenue from sale of power to

Accounts Receivable [Abstract]
Accounts receivable	5. Accounts receivable The Company’s accounts receivables are generated by selling energy to customers and are reported net of any allowance for uncollectible accounts. The Company uses ageing analysis, probability of default methods, past facts, significant one-time events, guidelines issued by government authorities, credit rating of customers, current economic conditions and reasonable forecasts that are most relevant in evaluating and estimating the expected credit losses. The Company writes-off an account receivable in the period that it is deemed uncollectible and records a reduction in the ECL and the balance of the account receivables in the balance sheet. The Company evaluates the concentration of risk with respect to its accounts receivables as high, due to the limited number of counterparts for its services, being mainly state utilities and government entities. However, the Company does not foresee any significant credit risk attached to receivables from such state utilities/government entities (also refer note 26 below). The Company analyzed its historical loss information for its accounts receivables and adjusted for forward looking information and determined the following credit loss percentages: March 31, 2022 March 31, 2021 Ageing of accounts receivables Expected Credit Expected Credit Not Due (including unbilled receivables) 0.57 % 0.73 % 0-90 days 2.27 % 2.80 % 90-180 days 3.25 % 3.82 % 180-365 days 3.34 % 3.99 % Above 365 days 11.19 % 11.79 % March 31, March 31, (INR) (INR) Ageing of accounts receivables*# (In million) (In million) Not Due (including unbilled receivables) 7,656 2,924 0-90 days 360 516 90-180 days 192 388 180-365 days 405 421 Above 365 days 917 1,275 Total accounts receivables 9,530 5,524 * Includes INR 1 million (US$0.0 million) and INR 162 million relating to receivables of the Company’s rooftop business being classified as Assets held for sale for the year ended March 31, 2022 and 2021 respectively.

The Company had challenged the Letter before the High Court at Vijayawada, as well as the decision of the Government of Andhra Pradesh (“GoAP”) to constitute a High-Level Negotiation Committee to review, negotiate, and bring down” the solar energy purchase prices vide order dated July 1, 2019 (“HLNC Order”). The High Court vide its judgment dated September 24, 2019 (“Judgment”), whilst quashing the aforesaid Letter and HLNC Order, granted its implied blessing to Andhra Pradesh DISCOM to approach the Andhra Pradesh Electricity Regulatory Commission (“APERC”) for reduction of tariff by directing APSPDCL to make payment of outstanding and future invoices at the “interim” rate of Rs. 2.44/- per unit, till the dispute is resolved by APERC. Accordingly, the Company has filed a writ appeal challenging the Judgment, whereby the Company has inter alia sought: (i) setting aside of the Judgment to the limited extent of the direction to Discoms to make payment at the “interim” rate of Rs. 2.44 per unit and the implied blessing granted by the High Court to approach the APERC for reduction of tariff; and (ii) quashing of all actions undertaken by the respondents and/or restrain the respondents from taking any action seeking reduction of tariff under the concluded PPA and/or unilateral alteration of the terms of such PPA, pursuant to the directions in the Judgment, including quashing of the proceedings. Further, the appellate authority during several hearings had directed the DISCOM to remit the overdue receivables at interim rate. During the current year on March 15, 2022, High court of Andhra Pradesh, Amaravati has passed an order in favour of the Company and has directed the discom to make the payments of arrears with within six weeks from the date of this order, at the original rate of INR 5.89 per unit mentioned in PPAs. Subsequent to March 2022, the Company has received a letter from offtaker dated August 4, 2022, stating outstanding liability as at May 31, 2022, to be paid in 12 monthly installments. The Company has also received dues pursuant to the same.

Income Taxes [Abstract]
Income Taxes	13. Income Taxes The individual entities within the Company file individual tax returns as per the regulations existing in their respective jurisdictions. The fiscal year under the Indian Income Tax Act ends on March 31. A portion of the Company’s Indian operations qualify for deduction from taxable income because its profits are attributable to undertakings engaged in development of solar power projects under section 80-IA of the Indian Income Tax Act, 1961. This holiday is available for a period of ten consecutive years out of fifteen years beginning from the year in which the Company generates power (“Tax Holiday Period”). However, the exemption is only available to the projects completed on or before March 31, 2017. The Company anticipates that it will claim the aforesaid deduction in the last ten years out of fifteen years beginning with the year in which the Company generates power and when it has taxable income. Accordingly, its current operations are taxable at the applicable tax rates, based on eligibility criteria. The Company had adopted the provisions of ASC Topic 740 as they relate to uncertain income tax positions. Tax exposures can involve complex issues and may require extended periods to resolve. The Company does not have any uncertain tax positions requiring recognition. The Company reassesses its tax positions in light of changing facts and circumstances, such as the closing of a tax audit, refinement of an estimate, or changes in tax codes. To the extent that the final tax outcome of these matters differs from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision (benefit) for income taxes consists of the following: Year ended March 31, 2020 2021 2022 2022 INR INR INR US$ (In million) Current tax expense (1) 120 242 485 6.4 Withholding tax on interest on Inter-Company debt related to green bonds 258 384 367 4.8 Deferred income tax (benefit)/expense 111 (330 ) 464 6.1 Total 489 296 1,316 17.3 (1) Current tax on profit before tax. Current tax includes INR 42 million (US$0.6 million) for tax adjustment relating to earlier years Income/(loss) before income taxes is as follows: March 31, 2020 2021 2022 2022 (INR) (INR) (INR) (US$) (In million) Domestic operations 326 8 19 0.3 Foreign operations (2,174 ) (3,913 ) (829 ) (10.8 ) Total (1,848 ) (3,905 ) (810 ) (10.5 ) Net deferred income taxes on the consolidated balance sheet is as follows: March 31, 2021 2022 2022 (INR) (INR) (US$) (In million) Deferred tax assets 2,836 4,201 55.4 Less: valuation allowance (1,088 ) (2,281 ) (30.1 ) Net deferred tax assets 1,748 1,920 25.3 Deferred tax liability 2,046 1,936 25.5 At March 31, 2022, the Company performed an analysis of the recoverability of the deferred tax asset. Based on the analysis, the Company has concluded that a valuation allowance offsetting the deferred tax assets is required. Change in the valuation allowance for deferred tax assets as of March 31, 2021 and March 31, 2022 is as follows: March 31, 2021 2022 2022 (INR) (INR) (US$) (In million) Opening valuation allowance 217 1,088 14.3 Movement during the Year* 871 1,193 15.8 Closing valuation allowance 1,088 2,281 30.1 * For financial year 2021 and 2022, The movement also includes INR 741 million and INR 843 million (US$ 11.1 million) respectively relating to capital loss on rooftop and other asset classified as held for sale. The movement for financial year 2021 and 2022 also includes INR 269 million and reversal of INR 125 million (US$ 1.6 million) respectively relating to other rooftop assets that are part of the sale agreement which are expected to be settled beyond 12 months. The significant components of the net deferred income tax assets and liabilities exclusive of amounts that would not have any tax consequences because they will reverse within the Tax Holiday Period, are as follows: As of March 31, 2021 2022 2022 (INR) (INR) (US$) (In million) Deferred tax assets: Net operating loss (a) 8,620 12,309 162.2 Tax on Inter — Company margin 320 210 2.8 Deferred revenue 466 503 6.6 Asset retirement obligation 191 232 3.1 Depreciation and amortization 102 - - Minimum alternate tax credit 612 765 10.1 Other deductible temporary difference 280 226 3.0 Capital loss on investment in rooftop and other assets 741 843 11.1 Valuation allowance (1,088 ) (2,281 ) (30.1 ) Deferred tax liabilities: Depreciation and amortization (9,697 ) (12,732 ) (167.8 ) Other comprehensive income (845 ) (91 ) (1.2 ) Net deferred tax (liability) asset (298 ) (16 ) (0.2 ) (a) Includes deferred tax on unabsorbed depreciation that can be carried forward indefinitely for set off as per income tax laws. APGL, the holding company and two of its subsidiaries incorporated in Mauritius have an applicable income tax rate of 15%. However, the group’s significant operations are based in India and are taxable as per the Indian Income Tax Act, 1961. For effective tax reconciliation purposes, the applicable tax rate in India has been considered. The income tax rate differs from the amount computed by applying the statutory income tax rate to loss before income taxes and is as follows: 2020 2021 2022 Tax (INR) % Tax (INR) % Tax (INR) % US$ Statutory income tax (benefit)/expense (646 ) 34.94 % (1,365 ) 34.94 % (283 ) 34.94 % (3.7 ) Temporary differences reversing in the Tax Holiday Period (386 ) 20.88 % (1,070 ) 27.40 % (9 ) (1.11 )% (0.1 ) Impact of changes in tax rate 3 (0.16 %) - - - - - Permanent timing differences 1,327 (71.81 %) 1,423 (36.44 %) 25 (3.05 )% 0.3 Valuation allowance created / (reversed) during the year (111 ) 6.03 % 871 (22.30 %) 1,193 (147.32 )% 15.7 Tax adjustment relating to earlier years - - - - 42 (5.19 )% 0.6 Withholding tax on interest on Inter-Company debt related to green bonds 258 (13.96 %) 384 (9.83 %) 367 (45.31 )% 4.8 Other difference 44 (2.38 %) 53 (1.36 %) (37 ) 4.57 % (0.5 ) Total 489 (26.46 %) 296 (7.58 %) 1,316 (162.46 )% 17.3 During the year end March 31, 2020, The Taxation Laws (Amendment) Act, 2019 has brought key changes to corporate tax rates in the Income Tax Act, 1961, which reduced the tax rate for certain subsidiaries within the group to 25.17%. Azure Power India Private Limited and several of its subsidiaries which are claiming tax benefits under section 80-IA of the Income Tax Act had decided not to opt for this lower tax benefit and have continued under the old regime for the fiscal year ended March 31, 2021 and 2022. The statutory income tax rate as per the Income Tax Act, 1961 ranges between 25.17% to 34.94%, depending on the tax regime chosen by the particular subsidiary. As of March 31, 2020, 2021, and 2022, deferred income taxes have not been provided for the Company’s share of undistributed net earnings of foreign operations due to management’s intent to reinvest such amounts indefinitely.

Earnings per share	17. Earnings per share The Company calculates earnings per share in accordance with FASB ASC Topic 260 Earnings Per Share and FASB ASC Topic 260-10-45 Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities. Basic and diluted earnings losses per equity share give effect to the change in the number of equity shares of the Company. The calculation of basic earnings per equity share is determined by dividing net profit/loss attributable to APGL equity shareholders by the weighted average number of equity shares outstanding during the respective periods. The potentially dilutive shares, consisting of employee share options have been included in the computation of diluted net earnings per share and the weighted average shares outstanding, except where the result would be anti-dilutive.

B) Guarantees The terms of our PPAs provide for the annual delivery of a minimum amount of electricity at fixed prices. Under the terms of the PPAs, we have issued irrevocable performance bank guarantees. These in total amount to INR 7,730 and INR 5,179 million (US$68.3 million) as of March 31, 2021 and 2022 respectively. As of March 31, 2021 and 2022, the Company has irrevocable performance bank guarantees aggregating to INR 5,366 million and INR 2,320 million (US$30.6 million) respectively, in relation to under construction projects. Further, bank guarantees of INR 516 million and INR 1,517 million (US$20.0 million) as of March 31, 2021 and 2022 respectively are in relation to commissioned projects as per respective PPAs and other project requirements. Bank guarantees amounting to INR 906 million and INR 458 million (US$6.0 million) as of March 31, 2021 and 2022 respectively, have been issued to meet Debt-Service Reserve Account (DSRA) requirements for outstanding loans. We have also obtained guarantees from financial institutions as a part of the bidding process for establishing solar projects amounting to INR 932 million and INR 873 million (US$11.5 million) as of March 31, 2021 and 2022 respectively.

The funds released from maturity/settlement of existing bank guarantees can be used for future operational activities. C) Contingencies A PIL had been initiated by certain individuals claiming to be wildlife experts/interested in conservation of wildlife, before the Supreme Court of India against various state governments such as Rajasthan, Gujarat, and MNRE, MOP among others, seeking protection of the two endangered bird species, namely the GIB and the Lesser Florican found in the states of Rajasthan and Gujarat. The Supreme Court by way of order dated April 19, 2021 issued directions to: (i) underground all low voltage transmission lines, existing and future lines falling in potential and priority habitats of GIB, (ii) to convert all existing high voltage lines in priority and potential areas of GIB where found feasible within a period of one year, if not found feasible, the matter to be referred to the committee formed by the Supreme Court which will take a decision on feasibility, and (iii) to install bird diverters on all existing overhead lines in the interim. We and many other developers have projects in the potential area as determined by the court, hence aggrieved by the order, the Solar Power Developers Association (“SPDA”) and Union of India have filed an application before the Supreme Court seeking among others, exemption from undergrounding of transmission lines in potential areas. The matter was last listed on November 30, 2022, whereby directions have been passed to parties to ensure installation of bird diverters in the Priority Area and for them to be in compliance with quality standards issued by the Supreme Court Committee. The PIL is presently pending. The SPDA has filed an application seeking modification of Supreme Court’s order dated April 19, 2021. If the modification application is dismissed, we might entail significant costs and delays. Based on evaluation of management the capital outflow for acquisition and installation of bird divertors are not material.

Under the ESOP Plans, the Compensation Committee on behalf of Board of Directors (the “Directors”) may from time to time make grants to one or more employees, determined by it to be eligible for participation under the plans. The Compensation Committee determines which employees are eligible to receive the equity awards, the number of equity awards to be granted, the exercise price, the vesting period and the exercise period.

Total options available for grant as of March 31, 2022 was 457,114 ESOPs. The Black-Scholes-Merton option pricing model includes assumptions regarding dividend yields, expected volatility, expected option term, and risk-free interest rates. The Company estimates expected volatility based on the historical volatility of the Company (considering sufficient history of its own data is available now for identifying the volatility). The risk-free interest rate is based on the yield of relevant time period based on US government bonds in effect at the time of grant for a period commensurate with the estimated expected life. The expected term of options granted is derived using the “simplified” method as allowed under the provisions of ASC Topic 718 to provide a reasonable basis upon which to estimate expected term.

Assets Held for Sale [Abstract]
Impairment of assets and Assets held for sale	23. Impairment of assets and Assets held for sale In April 2021, the Company has entered into an agreement with Radiance to sell certain subsidiaries (the “Rooftop Subsidiaries”) with an operating capacity of 153 MW (the “Rooftop Portfolio”) for INR 5,350 million, subject to certain purchase price adjustments (the “Rooftop Sale Agreement”). Pursuant to the Rooftop Sale Agreement, Radiance will acquire 100% of the equity ownership of the Rooftop Subsidiaries owned by the Group. The Company had recognized an impairment loss in relation to the Rooftop Subsidiaries aggregating to INR 3,255 million during the year ended March 31, 2021, pursuant thereto these assets (net) are carried at its fair values in the financial statements. As per the terms of the Rooftop Sale Agreement in respect to 43.2 MW operating capacity that are part of the Restricted Groups (as defined in the respective Green Bond Indentures) 48.6% of the equity ownership has been transferred to Radiance on the closing date, and pursuant to the terms of the Green Bond Indentures, the remaining 51.4% may only be transferred post refinancing of the Green Bonds. During the current year in August 2021, post refinancing of 5.5% Senior Notes and repayment of loan relating to one of a rooftop project of 10 MW, the restriction on transfer of shareholding was released and related assets and liabilities of the SPV have been reclassified as assets held for sale. Further, the loan repaid by the Company relating to this 10 MW project will be recovered from Radiance. The transfer of ownership for the remaining operating capacity of 33.2 MW for the Solar Green Bonds is not anticipated to occur within 12 months, hence, the assets and liabilities of these subsidiaries are not presented as “Assets classified as held for sale” and instead continue to be classified within the respective balance sheet captions in the consolidated financial statements at March 31, 2022 and March 31, 2021 respectively. There is also a restriction on transfer of equity ownership relating to the 16 MW project with Delhi Jal Board (DJB), wherein 49% of the equity ownership will be transferred to Radiance on closing date, and the remaining 51% will be transferred on or after March 31, 2024. Accordingly, the related assets and liabilities of the DJB 16 MW project are not presented as “Assets classified as held for sale” and instead continue to be classified within the respective balance sheet captions at March 31, 2022 and March 31, 2021 respectively. In May 2021, the Company has disposed its investment in a subsidiary on a going concern basis for consideration of INR 123 million (US$1.7 million). The same was reported as asset held for sale under financials for the year ended March 31, 2021. In February 2022, the Company has also executed a revised agreement with Radiance and transferred 100% shareholding in relation to 15.9 MW operating MW of rooftop entities (including 10 MW where restriction on account of Bonds was released post refinancing), 48.6% of the equity ownership of entities forming part of Restricted Groups having 33.2 MW operating capacity and 49% of the equity ownership relating to the 16 MW project with Delhi Jal Board (DJB). Further, subsequent to year end, Company has transferred 100% shareholding in relation to 2.5 MW operating capacity In the event the sale of the Rooftop Subsidiaries does not occur, the Company must reimburse Radiance the equity value of the assets not transferred along with an 10.5% per annum equity return. On May 27, 2023, Radiance have sent the Company a notice to terminate the Master Share Purchase Agreement in relation to 86.5 MW Rooftop portfolio. The Company is in discussion with Radiance to mutually terminate the transfer in shareholding of the remaining un-transferred 86.5 MW portfolio to Radiance, and the same shall be subject to modification of the Amended Rooftop Sale Agreement. Accordingly, the assets and related liabilities of these subsidiaries are not presented as “Assets classified as held for sale” and instead re-classified within the respective balance sheet captions in the consolidated balance sheet as at March 31, 2022. The assets and liabilities of the Rooftop Subsidiaries classified as held for sale, together with the calculation of the related impairment loss is shown below.

The fair value of consideration related to the rooftop sale in previous year includes expected recovery of VGF for INR 463 million (US$6.1 million). The Company has undertaken to refund to the purchaser an amount equivalent to 85% of any shortfall in recovery of VGF. Based on the current circumstances, management has assessed that they have complied with the conditions associated with the grant of VGF and hence have determined that the recovery of the VGF is likely. During the current year ended March 31, 2022, in respect of the 33.2 MW operating capacity that are part of the Restricted Groups, and 16 MW project with Delhi Jal Board, the Company has consolidated the entities in the consolidated financial statements and net carrying value of assets are reinstated.

Fair Value Measurements [Abstract]
Fair Value Measurements	24. Fair Value Measurements ASC Topic 820 Fair Value Measurements and Disclosures defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly, hypothetical transaction between market participants at the measurement date. ASC Topic 820 establishes a three-tier value hierarchy of fair value measurement based upon the whether the inputs to that measurement are observable or unobservable. Observable inputs reflect data obtained from independent sources while unobservable inputs reflect the Company’s market assumptions. ASC Topic 820 prioritizes the inputs used in the valuation methodologies in measuring fair value as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Includes other inputs that are directly or indirectly observable in the marketplace. Observable inputs, other than Level 1 quoted prices for similar instruments in active markets; quoted prices for similar or identical instruments in markets that are not active; and valuations using models in which all significant inputs are observable in active markets. Level 3 — Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In accordance with ASC Topic 820, assets and liabilities are to be measured based on the following valuation techniques: Market approach — Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income approach — converting the future amounts based on the market expectations to its present value using the discounting methodology. Cost approach — Replacement cost method. The valuation techniques used by the Company to measure and report the fair value of certain financial assets and liabilities on a recurring basis are as follows; Foreign exchange derivative contracts The Company enters into foreign exchange option contracts to hedge fluctuations in foreign exchange rates for recognized balance sheet items such as foreign exchange term loans. The Company mitigates the credit risk of these foreign exchange option contracts by transacting with highly rated counterparties which are major banks. The Company uses valuation models to determine the fair value of the foreign exchange option contracts. The inputs considered include the theoretical value of a call option, the underlying spot exchange rate as of the balance sheet date, the contracted price of the respective option contract, the term of the option contract, the implied volatility of the underlying foreign exchange rates and the risk-free interest rate as of the balance sheet date. The techniques and models incorporate various inputs including the credit worthiness of counterparties, foreign exchange spot and forward rates, interest rate yield curves, forward rate yield curves of the underlying option contracts. The Company classifies the fair value of these foreign exchange option contracts in Level 2 because the inputs used in the valuation model are observable in active markets over the term of the respective option contracts.

Whistle-blower Allegations and

Whistle-blower Allegations and Special Committee Investigation	12 Months Ended

Whistle-blower Allegations and Special Committee Investigation [Abstract]
Whistle-blower Allegations and Special Committee Investigation	27. Whistle-blower Allegations and Special Committee Investigation In June and July 2021, we received whistle-blower complaints alleging corrupt conduct in acquisition of land, improper use of political connections, special treatment of certain employees, payment of kickbacks, and improper conduct by our “sales team” (this specific allegation was later determined to be a hoax). Our Ethics Committee, supervised by the Board’s Audit and Risk Committee and with the support of outside counsel and forensic accounting professionals, conducted a fulsome investigation into these allegations and found none to be substantiated. We nonetheless implemented enhancements to our compliance program recommended by our advisors after the investigations had concluded. In addition, on October 1, 2021, the Enforcement Directorate of India filed a Prosecution Complaint with a special court in New Delhi in respect of an earlier Enforcement Case Information Report. Our former Group Chief Financial Officer and current Chief Financial Officer of our subsidiary APIPL, Mr. Pawan Kumar Agrawal, is one of those named and charged with the commission of offences under Sections 3 and 4 of the Prevention of Money Laundering Act, 2002 of India in relation to Mr. Agrawal’s prior employment. The relevant transactions that are the subject of the complaint predated Mr. Agrawal’s tenure as an employee and as Chief Financial Officer of the Company, and the criminal charges are not directed at, and do not concern, the Company or its subsidiaries. We will continue to monitor the proceedings as Mr. Agrawal defends the charges made against him. In May 2022, we received a whistle-blower complaint that alleged health and safety lapses, procedural irregularities, misconduct by certain employees, improper payments and false statements relating to one of our projects belonging to a project subsidiary. Following extensive investigation by the Ethics Committee, supervised by the Board’s Audit and Risk Committee and by external counsel and forensic professionals, we identified evidence of manipulation and misrepresentation of project data by some employees at that project site. Weak controls over payments to a vendor and failures to provide accurate information both internally and externally were found, but no direct evidence that any improper payment was made to any government official was identified. Further, in Fiscal 2023, we reported to SECI that this project had (i) shortfalls in generation and (ii) that it failed to timely complete and commission the requisite contractually required capacity. On January 3, 2023 and January 4, 2023, SECI advised us, inter alia, that the project may be liable for damages and penalties for shortfalls in generation and for not commissioning the full capacity required under its PPA in a timely manner. In September 2022, we received an additional whistle-blower complaint primarily making similar allegations of misconduct as raised in the May 2022 complaint, as well as allegations of misconduct related to joint ventures and land acquisition, allegations of our failure to be transparent with the market and advisors and other allegations. The Ethics Committee, supervised by the Board’s Audit and Risk Committee, with the support of external counsel and forensic accounting professionals, investigated these September 2022 allegations. The investigation of the September 2022 complaint identified significant control issues in the process of acquiring land and land use rights in relation to one of our projects. The investigation specified that third party land aggregators may have been involved in improper payments but no improper transfer of money by the Group was identified. We have made an adjustment (de-capitalization) in the books of accounts of INR 135 million (US$ 1.8 million) on estimate, as a prudent measure in the given project. Further, we have reviewed the entire amount paid to land aggregators in other projects to identify any similar issue and after an assessment a further adjustment (decapitalisation) aggregating to INR 118 million (US$ 1.6 million) has been made in the books of account on estimate, as a prudent measure, though no improper payments by the Group could be identified. We also identified potential misrepresentations made by former executives to the Board in July 2021 regarding an asset purchase transaction for the development of a wind project. In addition, it appears our former executive officers may have circumvented internal policies in connection with the approval of another transaction related to another wind project. We were not able to identify any evidence of improper payments related to either of these transactions. Considering the observations regarding the transactions, we have reassessed the valuation of the asset purchase and related government orders and did not find any adjustment that needed to be made in the books of account. Our investigation did not substantiate other portions of this September 2022 whistle-blower complaint. As part of our investigations of the May 2022 and September 2022 whistle-blower complaints, we also widened our review to include a review of projects commissioned in Fiscal 2022 and Fiscal 2023 to ensure that similar weaknesses were not present. As part of our investigations, we identified inconsistencies in project data in certain of our projects, but we identified no improper payments made in connection with these projects. We have taken a range of actions due to these findings, and the employees involved in the misconduct are no longer associated with us. In accordance with the recommendations of the Ethics Committee, the Board’s Audit and Risk Committee and their legal and forensic advisors, we are implementing remedial measures in both project control and monitoring. Further, we reported the findings from its investigations of the May 2022 and September 2022 whistle-blower complaints to the SEC and the U.S. Department of Justice, and we continue to cooperate with these authorities. In addition, a Special Committee of the Board of Directors (the “Special Committee”) was convened in August 2022 to review certain material projects and contracts over a three-year period for anti-corruption and related compliance issues. Independent outside counsel and forensic advisors were engaged to support the Special Committee. The Special Committee’s investigation has identified evidence that former executives were involved in an apparent scheme with persons outside the Company to make improper payments in relation to a project but no related improper payments or transfers by the Group have been identified. The Special Committee’s review and its findings could impact our decision-making in connection with such projects. We have disclosed the details of the Special Committee’s investigation to the SEC and the U.S. Department of Justice, and we continue to cooperate with those agencies. Our Group including our subsidiaries with respect to affected projects could be exposed to liabilities under the relevant contractual and tender documents (including levy of damages and liquidated damages, reduction of PPA tariffs and/or short closure of capacity), administrative actions (including the risk of PPA cancellation, risk of being debarred from SECI’s future contracts, withdrawal or nullification of commissioning certificates and/or revocation of commissioning extensions) and penalties from customers and other civil liabilities, all of which could adversely impact the revenue, profitability and capitalization of the affected projects. In addition, fines and/or penalties by regulatory authorities (including by the SEC, the U.S. Department of Justice and applicable Indian regulatory authorities) could be imposed on us. Any such fines or penalties could materially and adversely affect our business, results of operations, financial condition and cash flows in future periods. In addition, we could be exposed to future litigation in connection with any findings of fraud, corruption, or other misconduct by our employees and former employees and executives.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	12 Months Ended
	Mar. 31, 2022
Summary of Significant Accounting Policies [Abstract]
Basis of presentation	(a) Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and are presented in Indian rupees (“INR”), unless otherwise stated. The consolidated financial statements include the accounts of APGL and companies which are directly or indirectly controlled by APGL. All intercompany accounts and transactions have been eliminated upon consolidation. Certain balances relating to prior years have been reclassified, wherever required, to conform to the current year presentation. All share and per share amounts presented in the consolidated financial statements have been adjusted to reflect the 16-for-1 stock split of the Company’s equity shares that was effective on October 6, 2016.
Use of estimates	(b) Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs, expenses and comprehensive loss/ gain that are reported and disclosed in the consolidated financial statements and accompanying notes. These estimates are based on management’s best knowledge of current events, historical experience, actions the Company may undertake in the future and on various other assumptions that are believed to be prudent and reasonable under the circumstances. Significant estimates and assumptions are used for, but not limited to impairment of and useful lives of property, plant and equipment, determination of asset retirement obligations, valuation of derivative instruments, hedge accounting, lease liabilities, right to use asset, allowances for doubtful accounts based on payment history, credit rating, valuation of share-based compensation, income taxes, energy kilowatts expected to be generated over the useful life of the solar power plant, estimated transaction price, including variable consideration, of the Company’s revenue contracts, impairment of other assets, impairment of net assets classified as held for sale and other contingencies and commitments. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates, and such differences may be material to the consolidated financial statements. Estimation uncertainty relating to COVID-19 pandemic In evaluating the recoverability of accounts receivable including unbilled revenue, contract assets, long-lived assets and investments, the Company has considered, at the date of approval of these consolidated financial statements, internal and external information in the preparation of the consolidated financial statements including the economic outlook. The Company has performed sensitivity analysis on the assumptions used to assess the recoverability of these assets and based on current estimates, expects the carrying amount of these assets will be recovered. Based on the current collection experience the Company has not seen a material impact on accounts receivables collections due to COVID-19. The impact of COVID-19 may be different from that estimated on preparation of these consolidated financial statements and the Company will continue to closely monitor any material changes to future economic conditions. See also Note 2 (ab) - Impact of COVID-19 Pandemic. Principles of Consolidation The accompanying consolidated financial statements include the accounts of APGL, its subsidiaries, and variable interest entities (“VIE”), where the Company has determined it is the primary beneficiary and are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company uses the equity method to account for its investments in entities where it exercises significant influence over operating and financial policies but does not retain control under either the voting interest model (generally 20% to 50% ownership interest) or the variable interest model. In 2020, the Company entered into a joint venture agreement with a third party to establish a manufacturing facility to supply solar PV modules as a part of execution of manufacturing linked tender. Further during the current year, the Company has entered into an agreement with other party and made an initial investment in equity shares of its identified subsidiary as part of execution of contract, as further described in Note 10—Investments, and these investment are accounted for using the equity method. The Company has eliminated all intercompany accounts and transactions.
Foreign currency translation and transactions	(c) Foreign currency translation and transactions The functional currency of APGL is the United States Dollar (“US$”) and reporting currency is Indian rupees (“INR”). The Company’s subsidiaries with operations in India use INR as the functional currency and the subsidiaries in the United States and Mauritius use US$ as the functional currency. The financial statements of APGL and its subsidiaries, other than subsidiaries with a functional currency of INR, are translated into INR using the exchange rate as of the balance sheet date for assets and liabilities, historical exchange rates for equity transactions and average exchange rate for the year for income and expense items. Translation gains and losses are recorded in accumulated other comprehensive income or expenses as a component of shareholders’ equity. Transactions in currencies other than the functional currency are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the functional currency are translated into the functional currency using the exchange rate at the balance sheet date. All gains and losses arising from foreign currency transactions are recorded in the determination of net income or loss/(gain) during the year in which they occur. Revenue, expense and cash flow items are translated using the average exchange rates for the respective period. The resulting gains and losses from such translations are excluded from the determination of earnings and are recognized instead in accumulated other comprehensive loss/ (gain), which is a separate component of shareholders’ equity. Realized and unrealized foreign currency transaction gains and losses, other than those hedged by the Company, arising from exchange rate fluctuations on balances denominated in currencies other than the functional currency of an entity, such as those resulting from the Company’s borrowings in other than functional currency is included in Loss/(gain) on foreign currency exchange, net in the consolidated statements of operations.
Convenience translation	(d) Convenience translation Translation of balances in the consolidated balance sheets and the consolidated statements of operations, comprehensive loss, shareholders’ equity and cash flows from INR into US$, as of and for the year ended March 31, 2022 are solely for the convenience of the readers and were calculated at the rate of US$1.00 = INR 75.87 , the noon buying rate in New York City for cable transfers in non U.S. currencies, as certified for customs purposes by the Federal Reserve Bank of New York on March 31, 2022 . No representation is made that the INR amounts could have been, or could be, converted, realized or settled into US$ at that rate on March 31, 2022, or at any other rate.
Cash and cash equivalents	(e) Cash and cash equivalents Cash and cash equivalents include demand deposits with banks, term deposits and all other highly liquid investments purchased with an original maturity of three months or less at the date of acquisition and that are readily convertible to cash. The Company has classified term deposits totaling INR 9,936 million and INR 10,482 million (US$138.2 million) as of March 31, 2021 and 2022, respectively, as cash and cash equivalents, because the Company has the ability to redeem these deposits at any time subject to an immaterial interest rate forfeiture. All term deposits are readily convertible into known amount of cash with no more than one day notice.
Restricted cash	(f) Restricted cash Restricted cash consists of cash balances restricted as to withdrawal or usage and relates to cash used to collateralize bank letters of credit supporting the purchase of equipment for solar power plants, bank guarantees issued in relation to the construction of the solar power plants within the timelines stipulated in PPAs and for certain debt service reserves required under the Company’s loan agreements. Restricted cash is classified into current and non-current portions based on the term of the deposit and the expiration date of the underlying restriction. The following table presents the components of cash and cash equivalents and restricted cash included in the consolidated balance sheets that sums to the total of such amounts in the Consolidated Statements of Cash Flows: March 31, 2020 2021 2022 2022 (INR) (INR) (INR) (US$) (In million) Current Assets Cash and cash equivalents 9,792 11,107 18,796 247.7 Restricted cash 4,877 4,881 3,784 49.9 Non-Current Assets Restricted cash 848 170 726 9.6 Cash and cash equivalents and restricted cash 15,517 16,158 23,306 307.2
Investments	(g) Investments The Company determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation at each balance sheet date. The investment securities held by the Company during the periods presented in the accompanying consolidated financial statements are classified as available-for-sale (short-term investments), consisting of liquid mutual funds units and held-to-maturity investments (long-term investments), consisting of Notes of the Bank of Mauritius. The Company accounts for its investments in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 320, Accounting for Certain Investments in Debt and Equity Securities Securities that the Company has positive intent and ability to hold until maturity are classified as held-to-maturity securities and stated at amortized cost. As of March 31, 2021, and March 31, 2022, amortized cost of held-to-maturity investments was INR 7 million and INR 6 million (US$0.1 million), respectively. The maturity date of the investment is January 31, 2023. Realized gains and losses and a decline in value judged to be other than temporary on these investments are included in the consolidated statements of operations. The cost of securities sold or disposed is determined on the First in First Out (“FIFO”) method. Investment in equity investee The Company holds equity investments where it does not have a controlling financial interest but has the ability to exercise significant influence over the operating and financial policies of the investee. These investments are accounted for under the equity method of accounting wherein the Company records its proportionate share of the investee’s income or loss in its consolidated financial statements, as further described in Note 10—Investments
Accounts receivable, net	(h) Accounts receivable, net The Company adopted “ASC Topic 326” Financial Instruments — Credit Losses, effective April 1, 2020 using the modified retrospective transition approach. The new guidance requires the measurement and recognition of expected credit losses (ECL) for financial assets held at amortized cost and replaces the existing incurred loss impairment model with an expected loss model using the forward-looking information to calculate credit loss estimates. The new model requires consideration of a broader range of relevant information, such as offtake ratings historical loss experience, current economic conditions, and reasonable and supportable forecasts. The impact of adoption of this guidance did not have a material effect on the Company’s financial statements. Credit Risk Credit risk is the risk that counterparty will not meet its obligations under a financial instrument which consists principally of accounts receivables, cash and cash equivalents and restricted cash, leading to a financial loss. Customer credit risk is managed using the Company’s established policy, procedures and control relating to customer credit risk management. Outstanding accounts receivables are regularly monitored. The Company’s accounts receivables are generated by selling energy to customers and are reported net of any allowance for uncollectible accounts. The allowance for credit losses is based on various factors, including the length of time receivables are past due, significant one-time events, the financial health of customers and historical experience. The allowance for credit losses at March 31, 2021 and March 31, 2022 was INR 475 million and 285 million (US$3.8 million), respectively. Accounts receivable serve as collateral for borrowings under the Company’s working capital facility, described in Note 12.
Property, plant and equipment	(i) Property, plant and equipment Property, plant and equipment represents the costs of completed and operational solar power plants, as well as the cost of furniture and fixtures, vehicles, office and computer equipment, leasehold improvements, freehold land and construction in progress. Construction in progress represents the accumulated cost of solar power plants that have not been placed into service at the date of the balance sheet. Construction in progress includes the cost of solar modules for which the Company has taken legal title, civil engineering, electrical and other related costs incurred during the construction of a solar power plant. Construction in progress is reclassified to property, plant and equipment when the project begins its commercial operations. Property, plant and equipment are stated at cost, less accumulated depreciation and accumulated impairment losses. Depreciation is calculated using the straight-line method over the assets’ estimated useful lives as follows: Plant and machinery (solar power plants) 25-35 years Furniture and fixtures 5 years Vehicles 5 years Office equipment 1-5 years Computers 3 years Leasehold improvements related to office facilities are depreciated over the shorter of the lease period or the estimated useful life of the improvement. Lease hold improvements on the solar power plant sites are depreciated over the shorter of the lease term or the remaining period of the PPAs undertaken with the respective customer. Freehold land is not depreciated. Construction in progress is not depreciated until it is ready to be used. Improvements to property, plant and equipment deemed to extend the useful economic life of an asset are capitalized. Maintenance and repairs that do not improve efficiency or extend the estimated economic life of an asset are expensed as incurred. Additional capacity, if any, added to property plant and equipment is depreciated over the remaining estimated useful live. Capitalized interest Interest incurred on funds borrowed to finance construction of solar power plants is capitalized until the plant is ready for its intended use. The amount of interest capitalized during the years ended March 31, 2020, 2021 and 2022 were INR 355 million, INR 333 million and INR 595 million (US$7.8 million), respectively.
Accounting for impairment of long-lived assets	(j) Accounting for impairment of long-lived assets The Company periodically evaluates whether events have occurred that would require revision of the remaining useful life of property, plant and equipment and improvements, or render their carrying value not recoverable. If such circumstances arise, the Company uses an estimate of the undiscounted value of expected future operating cash flows to determine whether the long-lived assets are impaired. If the aggregate undiscounted cash flows are less than the carrying amount of the assets, the resulting impairment charge to be recorded is calculated based on the excess of the carrying value of the assets over the fair value of such assets, with the fair value determined based on an estimate of discounted future cash flows, appraisals, or other valuation techniques. Other than which relates to the planned disposal of the Company’s rooftop business, there were no
Leases and land use rights	(k) Leases and land use rights In February 2016, the FASB issued ASU 2016-02, Leases (“ASC Topic 842”), to increase transparency and comparability among organizations by recognizing a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months and disclosing key information about leasing transactions. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842) – Targeted Improvements, which provided an optional transition method to apply the new lease requirements through a cumulative-effect adjustment in the period of adoption. The Company adopted the guidance effective April 1, 2019 using the modified retrospective approach and elected certain practical expedients permitted under the transition guidance. The majority of the Company’s leases relate to leasehold land on which the solar power plants are constructed on and leases related to office facilities. The leasehold land related to solar power plants has a lease term ranging between 25 to 35 year which is further extendable on mutual agreement by both lessor and lessee. Where applicable, the company has the consent from the lessors to extend the leases up to 35 years. These leases have rent escalation ranging between 5% to 10%, over the tenure of the lease. All existing leases on the date of adoption of ASC Topic 842, were classified as operating leases as they were concluded at their inception under previous guidance of ASC Topic 840, as permitted by the practical expedient package elected. As the implicit rate in the lease contract is not readily determinable, the company has used its average incremental rate of borrowing of 10% for the purposes of the determination of discount rate. The weighted average remaining lease term for operating leases is 30 years. On Adoption of ASC 842, all the lease arrangements entered prior to adoption continued to be classified as operating leases. The Company has made an assessment for lease arrangements entered during the year and classified them as operating leases. The Company did not have any finance lease during any of the periods presented in the accompanying consolidated financial statements. The Company is a lessee in several non-cancellable operating leases, primarily for construction of solar power plants and for office facilities. The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date. For operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments include how the Company determines (1) the discount rate it uses to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments. ASC Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. Lease payments included in the measurement of the lease liability comprise of the following: ■ Fixed payments, including in-substance fixed payments, owed over the lease term (which includes termination penalties the Company would owe if the lease term assumes Company exercise of a termination option); ■ Variable lease payments, if any, that depend on an index or rate, initially measured using the index or rate at the lease commencement date; ■ Amounts expected to be payable under a Company-provided residual value guarantee; and ■ The exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise the option. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has recognized and reported the Right of Use asset, on consolidated balance sheet by INR 4,465 million (US$58.9 million) as well as Lease Liabilities by INR 3,834 million (US$50.5 million) as at March 31, 2022 and INR 4,214 million in Right of Use asset as well as Lease Liabilities by INR 3,642 million as at March 31, 2021 respectively. During the year ended March 31, 2021 and 2022, the Company recorded lease cost of INR 502 million and INR 439 million (US$5.8 million) respectively. See Note 18 to the consolidated financial statements. ROU assets for operating leases are periodically reduced by impairment losses. The Company uses the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to be recognized. See Note 2(j). The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero Operating lease ROU assets are presented as operating lease right -of -use assets on the consolidated balance sheet. The current portion of operating lease liabilities is included in other current liabilities and the long-term portion is presented separately as operating lease liabilities on the consolidated balance sheet. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases of warehouses, office, machinery etc. that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term. The Company’s corporate office leases generally also include non-lease maintenance services (i.e. common area maintenance). The Company allocates the consideration in the contract to the lease and non-lease maintenance component based on each component’s relative standalone price. The Company determines stand-alone prices for the lease components based on the prices for which other lessors lease similar assets on a stand-alone basis. The Company determines stand-alone prices for the non-lease components (i.e. maintenance services) based on the prices that several suppliers charge for maintenance services for similar assets on a stand-alone basis.
Asset retirement obligations (ARO)	(l) Asset retirement obligations (ARO) Upon the expiration of the land lease arrangement for solar power plants located on leasehold land, the Company is required to remove the solar power plant and restore the land. The Company records the fair value of the liability for the legal obligation to retire the asset in the period in which the obligation is incurred, which is generally when the asset is constructed. When a new liability is recognized, the Company capitalizes it by increasing the carrying amount of the related long-lived asset, which results in an ARO asset being depreciated over the remaining useful life of the solar power plant. The liability is accreted and expensed to its present expected future value each period based on a credit adjusted risk free interest rate. Upon settlement of the obligation, the Company eliminates the liability and based on the actual cost to retire, may incur a gain or loss. The Company’s asset retirement obligations were INR 811 million and INR 902 million (US$11.9 million) as of March 31, 2021 and 2022, respectively. The accretion expense incurred during the years ended March 31, 2020, 2021 and 2022 was INR 36 million, INR 42 million and INR 59 million (US$0.8 million), respectively. The depreciation expense incurred during the years ended March 31, 2020, 2021 and 2022 was INR 21 million, INR 23 million and INR 14 million (US$0.2 million), respectively. During the current year, the carrying amount of the ARO liability is increased by INR 91 million (US$1.2 million) primarily due to commissioning of new projects during the year partially offset by revision in the estimated cost of retirement obligation, with a corresponding adjustment to the related long-lived asset. The movement in liability during the current year as of March 31, 2022 and comparative year is as below: 2021 (INR) 2022 (INR) 2022 (US$) (In million) Beginning balance 741 811 10.7 Addition during the year 211 157 2.1 Impact of change in estimate (183 ) (125 ) (1.7 ) Liabilities settled during the year — — — Accretion expense during the year 42 59 0.8 Ending balance 811 902 11.9

Debt financing costs	(n) Debt financing costs Financing costs incurred in connection with obtaining construction and term financing loans are deferred and amortized over the term of the respective loan using the effective interest rate method. Amortization of debt financing costs is capitalized during construction and recorded as interest expense in the consolidated statements of operations, following commencement of commercial operations of the respective solar power plants. Amortization of debt financing costs for the years ended March 31, 2020, 2021 and 2022 was INR 709 million, INR 369 million and INR 1,107 million (US$14.6 million), including debt financing costs written off related to the debt refinancing amounting to INR 271 million, INR 30 million and INR 739 million (US$9.7 million), respectively. See Note 12. The carrying value of debt financing costs as on March 31, 2021 and 2022 was INR 1,107 million and INR 1,189 million (US$15.7 million), excluding the debt finance cost against borrowings which are reported as liabilities held for sale. See Note 12. Further, the Company had debt financing costs of INR 367 million and INR 141 million (US$1.9 million) under other assets and other current assets, as on March 31, 2021 and 2022, respectively for facilities not yet drawn. See Note 6.
Income taxes	(o) Income taxes Income taxes are recorded under the asset and liability method, as prescribed under ASC Topic 740 Income Taxes, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company establishes valuation allowances against its deferred tax assets when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The computation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company applies a two-step approach to recognize and measure uncertainty in income taxes in accordance with ASC Topic 740. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement through March 31, 2022, the Company does not have any unrecognized tax benefits, nor has it recognized any interest or penalties. During the year ended 2019-20, the Taxation Laws (Amendment) Act, 2019 brought key changes to corporate tax rates in the Income Tax Act, 1961, which reduced the tax rate for certain subsidiaries within the group to 25.17%. Azure Power India Private Limited and several of its subsidiaries which are claiming tax benefits under section 80-IA of the Income Tax Act had decided not to opt for this lower tax benefit and have continued under the old regime for the fiscal year ended March 31, 2022, the statutory income tax rate as per the Income Tax Act, 1961 ranges between 25.17% to 34.94%, depending on the tax regime chosen by the particular subsidiary.
Employee benefits	(p) Employee benefits Defined contribution plan Eligible employees of the Company in India receive benefits from the Provident Fund, administered by the Government of India, which is a defined contribution plan. Both the employees and the Company make monthly contributions to the Provident Fund equal to a specified percentage of the eligible employees’ salary. The Company has no further funding obligation under the Provident Fund, beyond the contributions elected or required to be made thereunder. Contributions to the Provident Fund by the Company are charged to expense in the period in which services are rendered by the covered employees and amounted to INR 37 million, INR 27 million and INR 27 million (US$0.4 million) for the years ended March 31, 2020, 2021 and 2022, respectively. Defined benefit plan Employees in India are entitled to benefits under the Gratuity Act, a defined benefit post-employment plan covering eligible employees of the Company. This plan provides for a lump-sum payment to eligible employees at retirement, death, and incapacitation or on termination of employment, of an amount based on the respective employee’s salary and tenure of employment. As of March 31, 2022, this plan is unfunded. Current service costs for defined benefit plans are accrued in the period to which they relate. In accordance with ASC Topic 715, Compensation Retirement Benefit- Compensated absences The Company recognizes its liabilities for compensated absences in accordance with ASC Topic 710, Compensation-General
Revenue recognition	(q) Revenue recognition Sale of power consists of solar energy sold to customers under long term Power Purchase Agreements (PPAs), which generally have a term of 25 years. The Company’s customers are generally the Government of India, power distribution companies and, to a lesser extent, commercial and industrial enterprises. Sale of power includes solar power sold through exchange. The Company recognizes revenue on PPAs when the solar power plant generates power and is supplied to the customer in accordance with the respective PPA. The company recognizes revenue each period based on the volume of solar energy supplied to the customer at the price stated in the PPA once the solar energy kilowatts are supplied and collectability is reasonably assured. The solar energy kilowatts supplied by the Company are validated by the customer prior to billing and recognition of revenue. Revenues from the recovery of safe-guard duties and goods and service tax under the change in law provision are recognized over the PPA period in the proportion of the actual sale of solar energy in kilowatts as per the terms agreed with customers or unless contractually agreed otherwise, once collectability is reasonably assured. Revenue from the sale of carbon credit emissions are recognized at the time of transfer of carbon credits to the customers, at consideration agreed under the sale agreements. The Company applies “ASC Topic 606” Revenue from Contracts with Customers, to recognize revenue from sale of power to its customers. Further, under Topic 606, total consideration for PPAs with scheduled price changes (price escalation is applicable in a solar power plant with 50 MW of operating capacity and price decrease in a solar power plant with 10 MW of operating capacity over the term of PPA) and for significant financing components, is estimated and recognized over the term of the agreement. Price escalations create an unbilled receivable, and the price decreases create deferred revenue. The time value of the significant financing component is recorded as interest expense. The Company uses the discount rate that would be reflected in a separate financing transaction between the entity and its customer at contract inception and recognizes the revenue amount on a straight-line basis over the term of the PPAs, and interest expense using the effective interest rate method. The Company also recognizes incremental costs incurred to obtain a contract in Other Assets in the consolidated balance sheet. These amounts are amortized on a straight-line basis over the term of the PPAs and are included as a reduction to revenue in the consolidated statements of operations. The Company also records the proceeds received from Viability Gap Funding (‘VGF’) on fulfilment of the underlying conditions as deferred revenue. Such deferred VGF revenue is recognized as sale of power in proportion to the actual sale of solar energy during the period to the total estimated sale of solar energy during the tenure of the applicable power purchase agreement or balance tenure of power purchase agreement, as applicable pursuant to the revenue recognition policy. Revenue from customers Revenue from customers, net consists of the following: Year ended March 31, 2020 2021 2022 2022 (INR) (INR) (INR) (US$) (In million) Revenue from Customers: Sale of Power (1) 12,958 15,133 17,621 232.2 Others (2) — 103 720 9.5 Total 12,958 15,236 18,341 241.7 (1) Sale of power includes revenue for the recovery of Safe-Guard Duties and Goods and Service Tax, which is linked to generation of Solar units, resulting from the change in law provision of our PPAs, during the year ended March 31, 2021 and 2022 amounting to INR 381 million and INR 340 million (US$4.5 million) respectively.

Cost of operations (exclusive of depreciation and amortization)	(r) Cost of operations (exclusive of depreciation and amortization) The Company’s cost of operations consists of expenses pertaining to operations and maintenance of its solar power plants. These expenses include payroll and related costs for maintenance staff, plant maintenance, insurance, and if applicable, lease costs etc. Depreciation expense is not included in cost of operations but is included within “Depreciation and amortization” expense, shown separately in the consolidated statements of operations.
General and administrative expenses	(s) General and administrative expenses General and administrative expenses include payroll and related costs for corporate, finance and other support staff, including bonus and share based compensation expense, professional fees and other corporate expenses.
Share based compensation	(t) Share based compensation The Company follows guidance under ASC Topic 718, Compensation — Stock Compensation administrative expenses and recognized in the consolidated statements of operations based on awards ultimately expected to The Company recognizes compensation expense for SARs based on the fair value of the amount payable to employees in respect of SARs, which are settled in cash, with a corresponding increase in liabilities, over the period that the employees unconditionally become entitled to the payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the SARs. Any changes in the fair value of the liability are recognized in consolidated statements of operations. The Company has elected to use the Black-Scholes-Merton valuation model to determine the fair value of share-based awards on the date of grant for employee share options with a fixed exercise price and fixed service-based vesting. The Company has elected to use the Black-Scholes-Merton valuation model to determine the fair value of SARs at each reporting date. Employee Stock Option and Restricted Stocks The share-based compensation expense related to share-based compensation is recorded as a component of general and administrative expenses in the Company’s consolidated statements of operations and totaled INR 17 million, INR 44 million and INR 69 million (US$0.9 million) for the years ended March 31, 2020, March 31, 2021, and 2022, respectively. The amount of share-based compensation expense capitalized during the year ended March 31, 2020, March 31, 2021, and 2022 was INR 13 million, INR 8 million and INR 23 million (US$0.3 million), respectively. Stock Appreciation Rights The share-based compensation expense related to SARs is recorded as a component of general and administrative expenses in the Company’s consolidated statements of operations totaled INR 1,319 million and reversal of expense of INR 373 million (US$4.9 million) for the year ended March 31, 2021, and 2022, respectively. The amount of share-based compensation expense capitalized during the years ended March 31, 2021, and 2022 was Nil
Assets held-for-sale	(u) Assets held-for-sale Assets and asset disposal group are classified as held-for-sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as met only when management commits to a plan to sell the asset; the asset is available for immediate sale in its present condition; an active program to locate a buyer and other actions required to complete the plan have been initiated; the sale of the asset is probable within one year or within extended period on account of conditions beyond the control of the Company; the asset is being actively marketed for sale at a reasonable price in relation to its current fair value; and it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Assets and liabilities classified as held-for-sale are measured at lower of their carrying amount and fair value less costs to sell and depreciation (amortization) ceases once the asset is classified as held for sale. See also, Note 23.
Contingencies	(v) Contingencies Liabilities for loss contingencies arising from claims, tax assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Legal costs incurred with respect to these items are expensed as incurred.
Fair value of financial instruments	(w) Fair value of financial instruments ASC Topic 820, Fair Value Measurements and Disclosures When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.
Derivatives and Hedging	(x) Derivatives and Hedging In the normal course of business, the Company uses derivative instruments for the purpose of mitigating the exposure from foreign currency fluctuation risks associated with forecasted transactions denominated in certain foreign currencies and to minimize earnings and cash flow volatility associated with changes in foreign currency exchange rates, and not for speculative trading purposes. These derivative contracts are purchased within the Company’s policy and are with counterparties that are highly rated financial institutions. Contracts designated as Cash Flow Hedge Cash flow hedge accounting is followed for derivative instruments to mitigate the exchange rate risk on foreign currency denominated debt instruments. Changes in fair value of derivative contracts designated as cash flow hedges are recorded in other comprehensive income/(loss), net of tax, until the hedge transaction occurs. The Company evaluates hedge effectiveness of cash flow hedges at the time a contract is entered into as well as on an ongoing basis or as required. When the relationship between the hedged items and hedging instrument is highly effective at achieving offsetting changes in cashflows attributable to the hedged risk, the Company records in other comprehensive income the entire change in fair value of the designated hedging instrument that is included in the assessment of hedge effectiveness. The cost of the hedge is recorded as an expense over the period of the contract on a straight-line basis. Fair value hedges: hedging of foreign exchange exposure Fair value hedge accounting is followed for foreign exchange risk with the objective to reduce the exposure to fluctuations in the fair value of firm commitments due to changes in foreign exchange rates. Fair value adjustments related to non-financial instruments will be recognized in the hedged item upon recognition and will eventually affect earnings as and when the hedged item is derecognized. Changes in the fair value of derivatives designated and qualifying as fair value hedges, together with any changes in the fair value of the hedged firm commitments attributable to the hedged risk, will be recorded in in the consolidated balance sheet. The gain or loss on the hedging derivative in a hedge of a foreign-currency-denominated firm commitment and the offsetting loss or gain on the hedged firm commitment is recognized in earnings in the accounting period, post the recognition of the hedged item in the balance sheet. Undesignated contracts Changes in fair value of undesignated derivative contracts are reported directly in earnings along with the corresponding transaction gains and losses on the items being economically hedged. The Company enters into foreign exchange currency contracts to mitigate and manage the risk of changes in foreign exchange rates. These foreign exchange derivative contracts were entered into to hedge the fluctuations in foreign exchange rates for recognized balance sheet items such as the Company’s U.S. dollar denominated borrowings. The Company has not designated the derivative contracts as hedges for accounting purposes. Realized gains (losses) and changes in the fair value of these foreign exchange derivative contracts are recorded in Loss (gain) on foreign currency exchange, net in the consolidated statements of operations. These derivatives are not held for speculative or trading purposes.
Segment information	(y) Segment information Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief executive officer is the chief operating decision maker. Based on the financial information presented to and reviewed by the chief operating decision maker in deciding how to allocate the resources and in assessing the performance of the Company, the Company has determined that it has a single operating and reporting segment: Sale of power. The Company’s principal operations, revenue and decision-making functions are located in India.

Refer to note 20. ** During the current year, the Company has entered into a sale agreement for the disposal of its rooftop business and has transferred the 48.6% and 49% shareholding of identified entities in reference to agreement and has recognized proportionate minority interest of INR 453 million (US$6.0 million) on transfer of its shareholdings of rooftop entities. See also Note 23
Recent accounting pronouncements	( aa In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”). This ASU eliminates certain exceptions to the general principles in ASC 740, Income Taxes and adds guidance to reduce complexity in accounting for income taxes. The ASU eliminates, inter alia, the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The ASU requires that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. ASU 2019-12 is effective for the annual periods beginning after December 15, 2020, including interim periods within those fiscal years. During current period, the Company applied ASU 2019-12 and noted that the impact of adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. In March 2020, the Financial Accounting Standards Board issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”).” ASU 2020-04 provides temporary optional expedients and exceptions to the guidance in U.S. GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. In January 2021, the FASB issued Accounting Standard Update (“ASU”) 2021-01 (Topic 848), which amends and clarifies the existing accounting standard issued in March 2020 (“ASU”) 2020-04 for Reference Rate Reform. Reference rates such as LIBOR, are widely used in a broad range of financial instruments and other agreements. The ASU permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, for computing variation margin settlements, and for calculating price alignment interest in connection with reference rate reform activities under way in global financial markets (the “discounting transition”). The ASU 2020-04 is effective for adoption at any time between March 12, 2020 and December 31, 2022, for all entities and the ASU 2021-01 is effective for all entities as of January 7, 2021 through December 31, 2022. As of March 31, 2022, the Company has not made any contract modifications to replace the reference rate in any of its agreements and will continue to evaluate the effects of this standard on its consolidated financial position, results of operations, and cash flows. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force) and the United States Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future financial statements.
Impact of COVID-19 Pandemic	( ab The Company has considered internal and external information in the preparation of the financial statements including the economic outlook and believes that it has taken into account the possible impact of known events arising out of the COVID-19 pandemic. The power plants had continued to remain operational during the COVID-19 pandemic, as electricity generation was designated as an essential service in India. Based on the current collection experience the Company has not seen a material impact on accounts receivables collections due to COVID-19.
