Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business Palo Alto Networks, Inc. (the “Company,” “we,” “us,” or “our”), headquartered in Santa Clara, California, was incorporated in March 2005 under the laws of the State of Delaware and commenced operations in April 2005. We empower enterprises, organizations, service providers, and government entities to secure their users, networks, clouds, and endpoints by delivering comprehensive cybersecurity backed by artificial intelligence and automation. Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), consistent in all material respects with those applied in our Annual Report on Form 10-K for the fiscal year ended July 31, 2022, filed with the Securities and Exchange Commission (“SEC”) on September 6, 2022. Our condensed consolidated financial statements include our accounts and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements are unaudited but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. Our condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2022. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. We base our estimates on assumptions, both historical and forward looking, that we believe are reasonable. Actual results could differ materially from those estimates due to risks and uncertainties, including uncertainty in the current economic environment. Summary of Significant Accounting Policies There have been no material changes to our significant accounting policies as of and for the six months ended January 31, 2023, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended July 31, 2022. Stock Split Effected in the Form of a Stock Dividend (“Stock Split”) On September 13, 2022, we executed a three-for-one stock split of our common stock, effected in the form of a stock dividend. The par value per share of our common stock remains unchanged at $0.001 per share after the Stock Split. All references made to share or per share amounts on the accompanying condensed consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect the effects of the Stock Split.

As of January 31, 2023, the gross unrealized losses that have been in a continuous unrealized loss position for less than 12 months were $17.2 million, which were related to $2.5 billion of available-for-sale debt securities, and the gross unrealized losses that have been in a continuous unrealized loss position for more than 12 months were $10.8 million, which were related to $571.6 million of available-for-sale debt securities. As of July 31, 2022 the gross unrealized losses that have been in a continuous unrealized loss position for less than 12 months were $24.8 million, which were related to $2.0 billion of available-for-sale debt securities, and the gross unrealized losses that have been in a continuous unrealized loss position for more than 12 months were not material.

Unrealized losses related to our available-for-sale debt securities are due to interest rate fluctuations as opposed to credit quality. We do not intend to sell any of the securities in an unrealized loss position and it is not likely that we would be required to sell these securities before recovery of their amortized cost basis, which may be at maturity. We did not recognize any credit losses related to our available-for-sale debt securities during the three and six months ended January 31, 2023 and 2022.

We enter into foreign currency derivative contracts with maturities of 24 months or less, which we designate as cash flow hedges, to manage the foreign currency exchange risk associated with our operating expenditures. As of January 31, 2023 and July 31, 2022, the total notional amount of our outstanding foreign currency forward contracts was $1.1 billion and $856.9 million, respectively. Refer to Note 3. Fair Value Measurements for the fair value of our derivative instruments as reported on our condensed consolidated balance sheets as of January 31, 2023 and July 31, 2022. As of January 31, 2023, unrealized gains in accumulated other comprehensive income (“AOCI”) related to our cash flow hedges were $14.2 million, of which $11.9 million of gains are expected to be recognized into earnings within the next 12 months. As of July 31, 2022, unrealized losses in AOCI related to our cash flow hedges were $24.8 million, of which $22.0 million of losses are expected to be recognized into earnings within the next 12 months.

Acquisitions

Acquisition

Cider Security Ltd.

On December 20, 2022, we completed our acquisition of Cider Security Ltd. (“Cider”), a privately-held cloud security company. We expect the acquisition will support Prisma Cloud’s platform approach to securing the entire application security lifecycle from code-to-cloud. The total purchase consideration for the acquisition of Cider was $198.3 million, which consisted of the following (in millions):


	Amount
Cash	$	198.0
Fair value of replacement awards	0.3
Total	$	198.3

As part of the acquisition, we issued replacement equity awards, which included 0.2 million shares of our restricted common stock. The total fair value of the replacement equity awards was $48.6 million, of which the portion attributable to services performed prior to the acquisition date was allocated to purchase consideration. The remaining fair value was allocated to future services and will be expensed over the remaining service periods as share-based compensation.

We have accounted for this transaction as a business combination and allocated the purchase consideration to assets acquired and liabilities assumed based on preliminary estimated fair values, as presented in the following table (in millions):


	Amount
Goodwill	$	164.6
Identified intangible assets	27.8
Cash	12.4
Net liabilities assumed	(6.5)
Total	$	198.3

Goodwill generated from this business combination is primarily attributable to the assembled workforce and expected post-acquisition synergies from integrating Cider technology into our platforms. The goodwill is expected to be deductible for U.S. income tax purposes.

Debt Disclosure [Abstract]

Debt

Convertible Senior Notes

In July 2018, we issued $1.7 billion aggregate principal amount of 0.75% Convertible Senior Notes due 2023 (the “2023 Notes”) and in June 2020, we issued $2.0 billion aggregate principal amount of 0.375% Convertible Senior Notes due 2025 (the “2025 Notes,” and together with the 2023 Notes, the “Notes”). The 2023 Notes bear interest at a fixed rate of 0.75% per year, payable semi-annually in arrears on January 1 and July 1 of each year, beginning on January 1, 2019. The 2025 Notes bear interest at a fixed rate of 0.375% per year, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. Each series of the convertible notes is governed by an indenture between us, as the issuer, and U.S. Bank National Association, as Trustee (individually, each an “Indenture,” and together, the “Indentures”). The Notes of each series are unsecured, unsubordinated obligations and the applicable Indenture governing each series of Notes does not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by us or any of our subsidiaries. The 2023 Notes and the 2025 Notes mature on July 1, 2023 and June 1, 2025, respectively. We cannot redeem the 2023 Notes prior to maturity. We may redeem for cash all or any portion of the 2025 Notes, at our option, on or after June 5, 2023, and prior to the 31st scheduled trading day immediately preceding the maturity date if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on and including the trading day preceding the date on which we provide notice of redemption. The redemption will be at a price equal to 100% of the principal amount of the 2025 Notes and adjusted for interest. If we call any or all of the 2025 Notes for redemption, holders may convert such 2025 Notes called for redemption at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date.

The following table presents details of our Notes (number of shares in millions):


	Conversion Rate per $1,000 Principal	Initial Conversion Price		Convertible Date	Initial Number of Shares
2023 Notes	11.2635	$	88.78	April 1, 2023	19.1
2025 Notes	10.0806	$	99.20	March 1, 2025	20.1

Holders of the Notes may surrender their Notes for conversion at their option at any time prior to the close of business on the business day immediately preceding their respective convertible dates only under the following circumstances:

•during any fiscal quarter commencing after the fiscal quarters ending on October 31, 2018 and October 31, 2020 for the 2023 Notes and the 2025 Notes, respectively (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price for the respective Notes on each applicable trading day (the “sale price condition”);

•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the applicable series of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate for the respective Notes on each such trading day; or

•upon the occurrence of specified corporate events.

On or after the respective convertible date, holders may surrender all or any portion of their Notes for conversion at any time prior to the close of business on the second scheduled trading day immediately preceding the applicable maturity date regardless of the foregoing conditions, and such conversions will be settled upon the applicable maturity date. Upon conversion, holders of the Notes of a series will receive cash equal to the aggregate principal amount of the Notes of such series to be converted, and, at our election, cash and/or shares of our common stock for any amounts in excess of the aggregate principal amount of the Notes of such series being converted.

The conversion price will be subject to adjustment in some events. Holders of the Notes of a series who convert their Notes of such series in connection with certain corporate events that constitute a “make-whole fundamental change” under the applicable Indenture are, under certain circumstances, entitled to an increase in the conversion rate for such series of Notes. Additionally, upon the occurrence of a corporate event that constitutes a “fundamental change” under the applicable Indenture, holders of the Notes of such series may require us to repurchase for cash all or a portion of the Notes of such series at a repurchase price equal to 100% of the principal amount of the Notes of such series plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The sale price condition for the Notes was met during the fiscal quarter ended January 31, 2023, and as a result, holders may convert their Notes at any time during the fiscal quarter ending April 30, 2023. The net carrying amount of the Notes was classified as a current liability on our condensed consolidated balance sheet as of January 31, 2023.

The following table sets forth the components of the Notes (in millions):


	January 31, 2023						July 31, 2022
	2023 Notes		2025 Notes		Total			2023 Notes		2025 Notes		Total
Liability component:
Principal	$	1,691.9	$	1,999.4	$	3,691.3		$	1,691.9	$	1,999.4	$	3,691.3
Less: debt discount and debt issuance costs, net of amortization	(1.2)		(9.8)		(11.0)			(2.6)		(11.9)		(14.5)
Net carrying amount	$	1,690.7	$	1,989.6	$	3,680.3		$	1,689.3	$	1,987.5	$	3,676.8

The total estimated fair value of the 2023 Notes and 2025 Notes were $3.0 billion and $3.3 billion at January 31, 2023, respectively, and $3.2 billion and $3.5 billion at July 31, 2022, respectively. The fair value was determined based on the closing trading price per $100 of the applicable series of the Notes as of the last day of trading for the period. We consider the fair value of the Notes at January 31, 2023 and July 31, 2022 to be a Level 2 measurement. The fair value of the Notes is primarily affected by the trading price of our common stock and market interest rates.

The following table sets forth interest expense recognized related to the Notes (dollars in millions):

Note Hedges

To minimize the impact of potential economic dilution upon conversion of our Notes, we entered into separate convertible note hedge transactions (the “2023 Note Hedges,” with respect to the 2023 Notes, the “2025 Note Hedges,” with respect to the 2025 Notes, and the 2023 Notes Hedges together with 2025 Note Hedges, the “Note Hedges”) with respect to our common stock concurrent with the issuance of each series of the Notes.

The following table presents details of our Note Hedges (in millions):


	Initial Number of Shares	Aggregate Purchase
2023 Note Hedges	19.1	$	332.0
2025 Note Hedges	20.1	$	370.8

The Note Hedges cover shares of our common stock at a strike price per share that corresponds to the initial applicable conversion price of the applicable series of the Notes, which are also subject to adjustment, and are exercisable upon conversion of the applicable series of the Notes. The Note Hedges will expire upon maturity of the applicable series of the Notes. The Note Hedges are separate transactions and are not part of the terms of the applicable series of the Notes. Holders of the Notes of either series will not have any rights with respect to the Note Hedges. Any shares of our common stock receivable by us under the Note Hedges are excluded from the calculation of diluted earnings per share as they are antidilutive. The aggregate amounts paid for the Note Hedges are included in additional paid-in capital on our condensed consolidated balance sheets.

Warrants

Separately, but concurrently with the issuance of each series of our Notes, we entered into transactions whereby we sold warrants (the “2023 Warrants,” with respect to the 2023 Notes, the “2025 Warrants,” with respect to the 2025 Notes, and the 2023 Warrants together with the 2025 Warrants, the “Warrants”) to acquire shares of our common stock, subject to anti-dilution adjustments. The 2023 Warrants and 2025 Warrants are exercisable beginning October 2023 and September 2025, respectively.

The following table presents details of our Warrants (in millions, except per share data):


	Initial Number of Shares	Strike Price per Share		Aggregate Proceeds
2023 Warrants	19.1	$	139.27	$	145.4
2025 Warrants	20.1	$	136.16	$	202.8

The shares issuable under the Warrants will be included in the calculation of diluted earnings per share when the average market value per share of our common stock for the reporting period exceeds the applicable strike price for such series of Warrants. The Warrants are separate transactions and are not part of either series of Notes or Note Hedges and are not remeasured through earnings each reporting period. Holders of the Notes of either series will not have any rights with respect to the Warrants. The aggregate proceeds received from the sale of the Warrants are included in additional paid-in capital on our condensed consolidated balance sheets.

Revolving Credit Facility

On September 4, 2018, we entered into a credit agreement (the “Credit Agreement”) with certain institutional lenders that provides for a $400.0 million unsecured revolving credit facility (the “Credit Facility”), with an option to increase the amount of the Credit Facility by up to an additional $350.0 million, subject to certain conditions. The Credit Facility matures on the earlier of (i) September 4, 2023 and (ii) the date that is 91 days prior to the stated maturity of our 2023 Notes if (a) any of the 2023 Notes are still outstanding and (b) our unrestricted cash and cash equivalents are less than the then outstanding principal amount of our 2023 Notes plus $400.0 million.

The borrowings under the Credit Facility currently bear interest, at our option, at a base rate plus a spread of 0.00% to 0.75%, or an adjusted LIBO Rate plus a spread of 1.00% to 1.75%, in each case with such spread being determined based on our leverage ratio. We are obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.125% to 0.250%, depending on our leverage ratio. In March 2021, the ICE Benchmark Administration, the administrator of LIBO Rate, announced that it will cease publication of the LIBO Rate by June 2023. Under the terms of our Credit Facility, in the event of the discontinuance of the LIBO Rate, a mutually agreed-upon alternative benchmark rate will be established to replace the LIBO Rate, which may include the Secured Overnight Financing Rate (“SOFR”). We do not anticipate that the discontinuance of the LIBO Rate will materially impact our liquidity or financial position.

As of January 31, 2023, there were no amounts outstanding and we were in compliance with all covenants under the Credit Agreement.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Additionally, we have a $159.6 million minimum purchase commitment with a service provider through September 2027 with no specified annual commitments.

Litigation

We are subject to legal proceedings, claims, and litigation arising in the ordinary course of business, including intellectual property litigation. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. We accrue for contingencies when we believe that a loss is probable and that we can reasonably estimate the amount of any such loss.

To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred and the amount of such additional loss would be material, we will either disclose the estimated additional loss or state that such an estimate cannot be made. As of January 31, 2023, we have not recorded any significant accruals for loss contingencies associated with such legal proceedings, determined that an unfavorable outcome is probable or reasonably possible, or determined that the amount or range of any possible loss is reasonably estimable.

Share Repurchase Program

In February 2019, our board of directors authorized a $1.0 billion share repurchase program, which is funded from available working capital. In December 2020, August 2021, and August 2022, our board of directors authorized additional $700.0 million, $676.1 million, and $915.0 million increases to this share repurchase program, respectively, bringing the total authorization under this share repurchase program to $3.3 billion (our “current authorization”). The expiration date of our current authorization was extended to December 31, 2023, and our repurchase program may be suspended or discontinued at any time. Repurchases may be made at management’s discretion from time to time on the open market, through privately negotiated transactions, transactions structured through investment banking institutions, block purchase techniques, 10b5-1 trading plans, or a combination of the foregoing.

The following table summarizes the share repurchase activity under our share repurchase program (in millions, except per share amounts):

In addition to the share repurchase activity summarized in the table above, during the six months ended January 31, 2023, we paid $22.7 million related to share repurchases of our common stock that were not settled as of July 31, 2022.

As of January 31, 2023, $750.0 million remained available for future share repurchases under our current repurchase authorization. The total price of the shares repurchased and related transaction costs are reflected as a reduction to common stock and additional paid-in capital on our condensed consolidated balance sheets.

Share-Based Payment Arrangement [Abstract]

Equity Award Plans

Restricted Stock Unit (“RSU”) and Performance-Based Stock Unit (“PSU”) Activities

The following table summarizes the RSU and PSU activity under our stock plans during the six months ended January 31, 2023 (in millions, except per share amounts):


	RSUs Outstanding			PSUs Outstanding
	Number of Shares	Weighted-Average Grant-Date Fair Value Per Share		Aggregate Intrinsic Value		Number of Shares	Weighted-Average Grant-Date Fair Value Per Share		Aggregate Intrinsic Value
Balance—July 31, 2022	14.8	$	115.51	$	2,456.9	3.1	$	106.38	$	513.7

Forfeited	(0.8)	$	119.48			(0.2)	$	135.26
Balance—January 31, 2023	15.4	$	133.47	$	2,442.8	4.5	$	124.21	$	711.5

______________

(1) For PSUs, shares granted represent the aggregate maximum number of shares that may be earned and issued with respect to these awards over their full terms.

Our RSUs generally vest over a period of three to four years from the date of grant. Until vested, RSUs do not have the voting and dividend participation rights of common stock and the shares underlying the awards are not considered issued and outstanding.

Our PSUs generally vest over a period of one to four years from the date of grant. The actual number of PSUs earned and eligible to vest is determined based on the level of achievement against certain performance conditions such as revenue growth, billings and operating margin, or individual performance for the fiscal year, or market conditions, or a combination of performance and market conditions for certain awards.

During the six months ended January 31, 2023, we granted 0.8 million shares of PSUs with both service and market conditions to certain employees. The market conditions are satisfied when the price of our common stock is equal to or exceeds stock price targets of $233.33, $266.67, $300.00, and $333.33 based on the average closing price for 30 consecutive trading days during the three- or four-year period following the date of grant. To the extent that the market conditions have been met, one-fourth of the awards will vest on each anniversary date of the grant date, subject to continued service. As of January 31, 2023, the stock price targets for these PSU awards have not been met.

During the six months ended January 31, 2023 and 2022, we granted 1.6 million and 0.6 million shares of PSUs, respectively, which contain service, performance and market conditions, to certain employees. The service conditions are satisfied over a period of one to three years. The performance conditions are based on revenue growth or billing growth. The market condition is measured based on our total shareholder return (“TSR”) relative to the TSR of the companies listed in the Standard & Poor’s 500 index. As of January 31, 2023, we have approved 2.3 million shares of PSUs, which will be granted upon the performance condition being established during the next two years.

The fair value of the PSUs subject to market conditions is estimated on the grant date using a Monte Carlo simulation model. The following table summarizes the assumptions used and the grant-date fair value of these PSUs granted:


	Six Months Ended
	January 31,
		2023		2022
Volatility		39.6% - 44.8%		36.0% - 38.0%
Expected term (in years)		1.0 - 4.0		1.9 - 3.0
Dividend yield		0.0	%	0.0	%
Risk-free interest rate		3.2% - 3.6%		0.2% - 0.4%
Grant-date fair value per share		$105.60 - $280.41		$137.16 - $140.22

Performance Stock Option (“PSO”) Activities

We have granted PSOs with both service and market conditions to certain executives. The market conditions were achieved when certain stock price targets were met. As of January 31, 2023, all stock price targets for our outstanding PSOs have been satisfied. One-fourth of the PSOs will vest on each anniversary date of the grant date, subject to continued service. The contractual term for the PSOs outstanding ranges from seven to seven and a half years following the date of grant in fiscal year 2018 and 2019.

The following table summarizes the PSO activity under our stock plans during the six months ended January 31, 2023 (in millions, except per share amounts):


	PSOs Outstanding
		Number of Shares	Weighted-Average Exercise Price Per Share		Weighted-Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
Balance—July 31, 2022		8.0	$	64.85	3.2	$	809.3



Balance—January 31, 2023		8.0	$	64.85	2.7	$	747.7
Exercisable—January 31, 2023		8.0	$	64.85	2.7	$	747.7

Share-Based Compensation

The following table summarizes share-based compensation included in costs and expenses (in millions):


	Three Months Ended				Six Months Ended
	January 31,				January 31,
	2023		2022		2023		2022
Cost of product revenue	$	2.6	$	2.3	$	5.0	$	4.6
Cost of subscription and support revenue	30.7		27.7		59.5		54.4
Research and development	129.7		123.6		247.7		249.2
Sales and marketing	88.4		79.8		175.8		153.1

Total share-based compensation	$	289.9	$	265.1	$	555.9	$	525.4

As of January 31, 2023, total compensation cost related to unvested share-based awards not yet recognized was $2.3 billion. This cost is expected to be amortized over a weighted-average period of approximately 2.7 years.

Income Taxes (Notes)	6 Months Ended
Income Taxes (Notes)	Jan. 31, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and six months ended January 31, 2023, our provision for income taxes reflected an effective tax rate of 0.2% and 12.3%, respectively. For the three and six months ended January 31, 2022, our provision for income taxes reflected an effective tax rate of negative 15.7% and negative 14.6%, respectively. Our income taxes for the three and six months ended January 31, 2023 were primarily due to U.S. federal and state income taxes, withholding taxes, and foreign income taxes. Our effective tax rate varied for the three and six months ended January 31, 2023 compared to the same periods in 2022 primarily due to an increase in current taxes driven by capitalization of research and development expenditures with no offsetting deferred benefit as a result of our valuation allowance. This increase was offset by a tax benefit from a release of tax reserves related to uncertain tax positions resulting from an agreement with a non-U.S. tax authority to pay $28.9 million to settle a tax audit during the three months ended January 31, 2023. Our income taxes for the three and six months ended January 31, 2022 were primarily due to foreign income taxes and withholding taxes. Our effective tax rates differed from the U.S. statutory tax rate primarily due to changes in our valuation allowance. As of January 31, 2023, our gross uncertain tax positions were $396.0 million and our interest and penalties were $6.7 million. We recognize both interest and penalties associated with uncertain tax positions as a component of income tax.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Net Income (Loss) Per ShareBasic net income (loss) per share is computed by dividing net income (loss) by basic weighted-average shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by diluted weighted-average shares outstanding during the period giving effect to all potentially dilutive securities to the extent they are dilutive. Potentially dilutive securities include shares issuable upon conversion of our convertible senior notes using the if-converted method. Potentially dilutive securities also include warrants related to the issuance of convertible senior notes and equity awards under our employee equity incentive plans using the treasury stock method.

The following table presents the computation of basic and diluted net income (loss) per share of common stock (in millions, except per share data):

Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), consistent in all material respects with those applied in our Annual Report on Form 10-K for the fiscal year ended July 31, 2022, filed with the Securities and Exchange Commission (“SEC”) on September 6, 2022. Our condensed consolidated financial statements include our accounts and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements are unaudited but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. Our condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2022.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. We base our estimates on assumptions, both historical and forward looking, that we believe are reasonable. Actual results could differ materially from those estimates due to risks and uncertainties, including uncertainty in the current economic environment.
