Accounting Policies [Abstract]  
Concentration of Credit Risk
Concentration of Credit Risk
Our financial instruments that are exposed to concentrations of credit risk principally consist of cash, cash equivalents, investments, and accounts receivable. Our investment portfolio consists of investment grade securities diversified amongst security types, industries, and issuers. All our securities are held in custody by a recognized financial institution. Our policy limits the amount of credit exposure to a maximum of 5% to any one issuer, except for the U.S. Treasury, and we believe no significant concentration risk exists with respect to these investments. We also mitigate counterparty risk through entering into derivative contracts with high-credit-quality financial institutions.
The majority of our licensing revenue is generated from customers outside of the U.S. We manage this risk by performing regular evaluations of the creditworthiness of our licensing customers. In fiscal 2021, 2020, and 2019, we did not have any individual customers whose revenue exceeded 10% of our total revenue.
Cash and Cash Equivalents
Cash and Cash Equivalents
We consider all short-term highly liquid investments with original maturities of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents primarily consist of funds held in general checking accounts, money market accounts, commercial paper, and government bonds.
Restricted Cash Restricted CashRestricted cash on our consolidated balance sheets consists of cash contributed by Dolby and third-party licensors to Via, our wholly-owned subsidiary, that may only be used for licensor enforcement actions or licensee compliance activities related to certain Via-administered patent pools, as well as to disperse costs associated with any audit of Via for the Wideband Code Division Multiple Access (W-CDMA) patent pool
Investments
Investments
All of our investments are classified as AFS, with the exception of our mutual fund investments held in our supplemental executive retirement plan, which are classified as trading securities. Investments that have an original maturity of 91 days or more at the date of purchase and a current maturity of less than one year are classified as short-term investments, while investments with a current maturity of more than one year are classified as long-term investments. Our investments are recorded at fair value in our consolidated balance sheets. Unrealized gains and losses on our AFS securities are reported as a component of AOCI, while realized gains and losses, other-than-temporary impairments, and credit losses are reported as a component of net income. Upon sale, gains and losses are reclassified from AOCI into earnings, and are determined based on specific identification of securities sold.
We evaluate our investment portfolio for credit losses and other-than-temporary impairments by comparing the fair value with the cost basis for each of our investment securities. An investment is impaired if the fair value is less than its cost basis. If any portion of the impairment is deemed to be the result of a credit loss, the credit loss portion of the impairment is included as a component of net income. If we deem it probable that we will not recover the full cost basis of the security, the security is other-than-temporarily impaired, and the impairment loss is recognized as a component of net income.
Allowance for Doubtful Accounts
Allowance for Credit Losses
We maintain a provision for estimated credit losses on receivables resulting from our customers' inability to make required payments. In determining the provision, we pool receivables with similar risk characteristics to evaluate the collectability of our accounts receivable. Risk characteristics considered in creating these risk pools include assessing historical or expected loss patterns, credit ratings, current economic conditions that could impact collectability of cash flows (such as the macroeconomic effects of COVID-19), and structure of customer agreements. In cases where circumstances have changed such that specific customers no longer share similar risk characteristics, customers are excluded from their current pool and their risk profiles are evaluated separately. We recognize allowances for credit losses based on our actual historical loss information, the current business environment, and reasonable and supportable forecasts. Actual future losses from uncollectible accounts may differ from our estimates.
Inventories
Inventories
Inventories are accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. We evaluate our ending inventories for estimated excess quantities and obsolescence. Our evaluation includes the analysis of future sales demand by product within specific time horizons. Inventories in excess of projected future demand are written down to their net realizable value. In addition, we assess the impact of changing technology on our inventory balances and write-off inventories that are considered obsolete. Write-downs and write-offs of inventory are recorded as a cost of products in our consolidated statements of operations. We classify inventory that we do not expect to sell within twelve months as other non-current assets in our consolidated balance sheets.
Property, Plant, and Equipment
Property, Plant, and Equipment
PP&E is stated at cost less accumulated depreciation. Depreciation expense is recognized on a straight-line basis according to estimated useful lives assigned to each of our different categories of PP&E as summarized within the following table:    
PP&E CategoryUseful Life
Computer equipment and software
3 to 5 years
Machinery and equipment
3 to 8 years
Furniture and fixtures
5 to 8 years
Leasehold improvementsLesser of useful life or related lease term
Equipment provided under operating leases
15 years
Buildings and building improvements
20 to 40 years
We capitalize certain costs incurred during the construction phase of a project or asset into construction-in-progress until the construction process is complete. Once the related asset is placed into service, we transfer its carrying value into the appropriate fixed asset category and begin depreciating the value over its useful life.
Equipment Provided Under Operating Leases.  In arrangements that we assess as operating leases, we recognize our cinema equipment installed at third-party sites as a fixed asset and depreciate the asset on a straight-line basis.
Internal Use Software Internal Use Software.  We account for the costs of computer software developed for internal use by capitalizing costs of materials and external consultants. These costs are included in PP&E, net of accumulated amortization in our consolidated balance sheets. Our capitalized internal use software costs are typically amortized on a straight-line basis over estimated useful lives of three to five years. Costs incurred during the preliminary project and post-implementation stages are charged to expense.
Goodwill, Intangible Assets, and Long-Lived Assets
Goodwill, Intangible Assets, and Long-Lived Assets
We perform an assessment of goodwill for potential impairment annually during our third fiscal quarter and whenever events or changes in circumstances indicate that the carrying amount may be impaired. We perform a qualitative assessment as a determinant for whether the annual goodwill impairment test should be performed. For fiscal 2021, we completed our annual goodwill impairment assessment in the fiscal quarter ended June 25, 2021. We determined in our qualitative review that it is more likely than not that the fair value of our reporting unit is substantially in excess of the respective carrying amount. Accordingly, there was no impairment, and the goodwill impairment test was not required. We did not incur any goodwill impairment losses in any of the periods presented.
Intangible assets are stated at their original cost less accumulated amortization, and those with definite lives are amortized over their estimated useful lives. Our intangible assets principally consist of acquired technology, patents, trademarks, customer relationships and contracts, the majority of which are amortized on a straight-line basis over their useful lives using a range from three to eighteen years.
We review long-lived assets, including intangible assets, for impairment whenever events or a change in circumstances indicate an asset’s carrying value may not be recoverable. Recoverability of an asset is measured by comparing its carrying value to the total future undiscounted cash flows that the asset is expected to generate. If it is determined that an asset is not recoverable, an impairment loss is recorded in the amount by which the carrying value of the asset exceeds its estimated fair value.
Revenue Recognition
Revenue Recognition
We enter into revenue arrangements with our customers to license technologies, trademarks and patents for sound, imaging and voice solutions, and to sell products and services. We recognize revenue when we satisfy a performance obligation by transferring control over the use of a license, product, or service to a customer.
For additional financial information and a summary of our accounting policy, refer to Note 3. "Revenue Recognition" to our consolidated financial statements.
Cost of Revenue
Cost of Revenue
Cost of licensing.  Cost of licensing primarily consists of amortization expenses associated with purchased intangible assets and intangible assets acquired in business combinations. Cost of licensing also includes IP royalty obligations to third parties, depreciation of our Dolby Cinema equipment provided under operating leases in collaborative arrangements, and direct fees incurred.
Cost of products and services.  Cost of products primarily consists of the cost of materials related to products sold, applied labor, and manufacturing overhead. Our cost of products also includes third party royalty obligations paid to license IP that we include in our products. Cost of services primarily consists of the personnel and personnel-related costs of employees performing our professional services, and those of outside consultants, and reimbursable expenses incurred on behalf of customers.
Stock-Based Compensation
Stock-Based Compensation
We measure expenses associated with all employee stock-based compensation awards using a fair-value method and record such expense in our consolidated financial statements on a straight-line basis over the requisite service period.
Advertising and Promotional Costs
Advertising and Promotional Costs
Advertising and promotional costs are charged to S&M expense as incurred. Our advertising and promotional costs were as follows (in thousands):

Income Taxes
Income Taxes
We use the asset and liability method, under which deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax bases of assets and liabilities, and NOL carryforwards are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets is additionally dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities and projected future taxable income in making this assessment, and we record a valuation allowance to reduce our deferred tax assets when it's more-likely-than-not that some portion or all of the deferred tax assets will not be realized.
We record an unrecognized tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the tax authorities. We include interest and penalties related to gross unrecognized tax benefits within our provision for income taxes. To the extent accrued interest and penalties do not ultimately become payable, amounts accrued are reversed in the period that such determination is made and are reflected as a reduction of the overall income tax provision.
Repatriation of Undistributed Foreign Earnings.  The Tax Act provides an exemption from federal income taxes for distributions by foreign subsidiaries made after December 31, 2017 that were not subject to the Transition Tax. Therefore, we have provided for U.S. state income taxes and foreign withholding taxes on undistributed earnings of certain foreign subsidiaries to the extent such earnings are no longer considered to be indefinitely reinvested in the operations of those subsidiaries. We consider the earnings of certain foreign subsidiaries to be indefinitely reinvested outside the U.S. on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs, and our specific plans for reinvestment of those subsidiary earnings.
Recently Issued Accounting Standards
Recently Issued Accounting Standards
We continually assess any ASUs or other new accounting pronouncements issued by the FASB to determine their applicability and impact on us. Where it is determined that a new accounting pronouncement will result in a change to our financial reporting, we take the appropriate steps to ensure that such changes are properly reflected in our consolidated financial statements or notes thereto.
Adopted Standards
Collaborative Arrangements. In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer. In addition, ASU 2018-18 precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. We adopted this standard in the first quarter of fiscal 2021 and it did not have a material impact on our consolidated financial statements.
Financial Instruments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments (Topic 326): Measurement of Credit Losses on Financial Instruments, which modifies the measurement of expected credit losses of certain financial instruments, including trade receivables, contract assets, and lease receivables. The standard
provides guidance regarding methodologies and disclosures for expected credit losses on financial instruments, resulting in immediate recognition of estimated credit losses over the remaining life of financial assets at initiation or purchase date. We adopted this standard in the first quarter of fiscal 2021, using the modified retrospective method. The adoption of this standard did not have a material impact on our consolidated financial statements.
Standards Not Yet Adopted
Revenue Recognition Revenue Recognition
We enter into revenue arrangements with our customers to license technologies, trademarks and patents for sound, imaging and voice solutions, and to sell products and services. We recognize revenue when we satisfy a performance obligation by transferring control over the use of a license, product, or service to a customer.
A. Identification of the Contract or Contracts with Customers
We generally determine that a contract with a customer exists upon the execution of an agreement and after consideration of collectability, which could include an evaluation of the customer's payment history, the existence of a standby letter-of-credit between the customer’s financial institution and our financial institution, public financial information, and other factors. At contract inception, we also evaluate whether two or more non-standard agreements with a customer should be combined and accounted for as a single contract.
B. Identification of Performance Obligations in a Contract
We generate revenue principally from the following sources, which represent performance obligations in our contracts with customers:
Licensing.   We license our technologies, including patents, to a range of customers who incorporate them into their products for enhanced audio, imaging and voice functionality across broadcast, mobile, CE, PC, gaming, and other markets.
Product Sales. We design and provide audio and imaging products for the cinema, television, broadcast, communications, and entertainment industries.
Services.   We provide various services to support theatrical and television production for cinema exhibition, broadcast, and home entertainment, including equipment training, mixing room alignment, equalization, as well as audio, color and light image calibration.
PCS. We provide PCS for products sold and for equipment leased, and we support the implementation of our licensing technologies in our licensees’ products.
Equipment Leases. We collaborate with established cinema exhibitors to offer Dolby Cinema, a branded premium cinema offering for movie audiences by leasing equipment and licensing our IP. We also lease hardware that facilitates the Dolby conferencing experience, including the Dolby Conference Phone, and the Dolby Voice Room solution.
Licensing Administration Fees. We generate service fees for managing patent pools on behalf of third party patent owners through our wholly-owned subsidiary, Via.
Some of our revenue arrangements include multiple performance obligations, such as hardware, software, support and maintenance, and extended warranty services. We evaluate whether promised products and services are distinct performance obligations.
The majority of our arrangements with multiple performance obligations pertain to our digital cinema server and processor sales that include the following distinct performance obligations to which we allocate portions of the transaction price based on their stand-alone selling price:
Digital cinema server hardware and embedded software, which is highly dependent on and highly interrelated with the hardware. Accordingly, the hardware and embedded software represent a single performance obligation.
The right to support and maintenance, which is included with the purchase of the digital cinema server hardware, is a distinct performance obligation.
The right to receive commissioning services is a distinct performance obligation within the sale of the Dolby Atmos Cinema Processor. These services consist of the review of venue designs specifying proposed speaker placement as well as calibration services performed for installed speakers to ensure optimal playback.
C. Determination of Transaction Price for Performance Obligations in a Contract
After identifying the distinct performance obligations, we determine the transaction price in accordance with the terms of the underlying executed contract which may include variable consideration such as discounts, rebates, refunds, rights of returns, and incentives. We assess and update, if necessary, the amount of variable consideration to which we are entitled for each reporting period. At the end of each reporting period, we estimate and accrue a liability for returns and adjustments as a reduction to revenue based on several factors, including past returns history.
With the exception of our sales-based royalties, we evaluate whether a significant financing component exists when we recognize revenue in advance of customer payments that occur over time. For example, some of our licensing arrangements include payment terms greater than one year from when we transfer control of our IP to a licensee and the receipt of the final payment for that IP. If a significant financing component exists, we classify a portion of the transaction price as interest income, instead of recognizing all of the transaction price as revenue. We do not adjust the transaction price for the effects of financing if, at contract inception, the period between the transfer of control to a customer and final payment is expected to be one year or less.
D. Allocation of Transaction Price to Distinct Performance Obligations in a Contract
For our sales-based royalties where the license is the predominant item to which the royalties relate, we present all revenue as licensing.
For revenue arrangements that include multiple performance obligations, we determine the stand-alone selling price for each distinct performance obligation based on the actual selling prices made to customers. If the performance obligation is not sold separately, we estimate the stand-alone selling price. We do so by considering market conditions such as competitor pricing strategies, customer specific information and industry technology lifecycles, internal conditions such as cost and pricing practices, or applying the residual approach method when the selling price of the good, most commonly a license, is highly variable or uncertain.
Once the transaction price, including any variable consideration, has been determined, we allocate the transaction price to the performance obligations identified in the contract and recognize revenue as or when control is transferred for each distinct performance obligation.
E. Revenue Recognition as Control is Transferred to a Customer
We generate our licensing revenue by licensing our technologies and patents to various types of licensees, such as chip manufacturers ("implementation licensees"), consumer product manufacturers, software vendors, and communications service providers. Our revenue recognition policies for each of these arrangements are summarized below.
Initial fees from implementation licensees.   Implementation licensees incorporate our technologies into their chipsets that, once approved by Dolby, are available for purchase by OEMs for use in end-user products. Implementation licensees only pay us a nominal initial fee on contract execution as consideration for the ongoing services that we provide to assist in their implementation process. Revenue from these initial fees are recognized ratably over the contractual term as a component of licensing revenue.
Sales-based licensing fees.   In our royalty bearing licensing agreements with OEMs, control is transferred upon the later of contract execution or the contract’s effective date. We apply the royalty exception, which requires that we recognize sales-based royalties when the sales occur based on our estimates. These estimates involve the use of historical data and judgment for several key attributes including industry estimates of expected shipments, the
percentage of markets using our technologies, and average sale prices. Generally, our estimates represent the current period’s shipments to which we expect our licensees to submit royalty statements in the following quarter. Upon receipt of royalty statements from the licensees with the actual reporting of sales-based royalties that we estimated previously, we record a favorable or unfavorable adjustment based on the difference, if any, between estimated and actual sales. In the first quarter of fiscal 2021, we recorded a favorable adjustment of approximately $21 million, which was primarily related to shipments that occurred in our fourth quarter of fiscal 2020 (July through September) and largely based on actual royalty statements received from licensees. In the second, third, and fourth quarters of fiscal 2021, we recorded favorable adjustments of $16 million, $14 million, and $3 million, respectively, each primarily related to shipments that occurred in the preceding fiscal quarter, and largely based on actual royalty statements received from licensees.
Fixed and guaranteed licensing fees.   In certain cases, our arrangements require the licensee to pay fixed, non-refundable fees. In these cases, control is transferred and fees are recognized upon the later of contract execution or the effective date. Additionally and separate from initial fees from implementation licensees, our sales- and usage-based licensing agreements include a nominal fee, which is also recognized at a point in time in which control of the IP has been transferred. Revenue from these arrangements is included as a component of licensing revenue.
Recoveries.   Through compliance efforts, we identify misreported licensed activity related to non-current periods. We may record a favorable or unfavorable revenue adjustment in connection with the findings from these compliance efforts generally upon resolution with the licensee through agreement of the findings, or upon receipt of the licensee’s correction statement. Revenue from these arrangements is included as a component of licensing revenue.
We undertake activities aimed at identifying potential unauthorized uses of our technologies, which when successful result in the recognition of revenue. Recoveries stem from third parties who agree to remit payments to us based on past use of our technology. In these scenarios, a legally binding contract did not exist at time of use of our technology, and therefore, we recognize revenue recoveries upon execution of the agreement as that is the point in time to which a contract exists and control is transferred. This revenue is classified as licensing revenue.
In general, we classify legal costs associated with activities aimed at identifying potential unauthorized uses of our technologies, auditing existing licensees, and on occasion, pursuing litigation as S&M in our consolidated statements of operations.
We recognize licensing revenue gross of withholding taxes, which our licensees remit directly to their local tax authorities, and for which we receive a partial foreign tax credit in our income tax provision.
In addition to our licensing arrangements, we also enter into arrangements to deliver products and services.
Product Sales.   Revenue from the sale of products is recognized when the customer obtains control of the promised good or service, which is generally upon shipment. Payments are generally made within 90 days of sale.
Services.   We provide various services, such as engineering services related to movie soundtrack print mastering, equipment training and maintenance, mixing room alignment, equalization, and image calibration, which we bill on a fixed fee and time and materials basis. Most of these services are of a short duration and are recognized as control of the performance obligations are transferred which is when the related services are performed.
Cloud Services. We provide access to media processing and interactivity APIs through our developer platform as well as cloud encoding services, generally, on either a consumption or subscription basis. Revenue related to cloud services provided on a consumption basis is recognized when the customer utilizes the services, based on the quantity of services consumed. Revenue related to cloud services provided on a subscription basis is recognized ratably over the contract term as the customer receives and consumes the benefits of the cloud services.
Collaborative Arrangements.   We collaborate with established cinema exhibitors to offer Dolby Cinema, a branded premium cinema offering for movie audiences. Under such collaborations, Dolby and the exhibitor are both active participants, and share the risks and rewards associated with the business. Accordingly, these collaborations are governed by revenue sharing arrangements under which Dolby receives revenue based on box office receipts, reported to Dolby by exhibitor partners on a monthly or quarterly basis, our proprietary designs and trademarks as well as for the use of our equipment at the exhibitor's venue. The use of our product solution meets the definition of a lease, and for the related portion of Dolby's share of revenue, we apply ASC 842, Leases, and recognize revenue based on monthly box office reports from exhibitors. Our revenue share is recognized as licensing revenue in our
consolidated statements of operations.
In addition, we also enter into hybrid agreements where a portion of our revenue share involves guaranteed payments, which in some cases result in classifying the arrangement as a sales-type lease. In such arrangements, we consider control to transfer at the point in time to which we have installed and tested the equipment, at which point we record such guaranteed payments as product revenue.
Via Administration Fee. We generate service fees for managing patent pools on behalf of third party patent owners through our wholly-owned subsidiary, Via. As an agent to licensors in the patent pool, Via receives a share of the sales-based royalty that the patent pool licensors earn from licensees. As such, we apply the sales-based royalty exception as the service provided is directly related to the patent pool licensors’ provision of IP, which results in recognition based on estimates of the licensee’s quarter shipments that use the pool’s patents. In addition to sales-based royalties, Via also has contracts where the fees are fixed. The revenue share Via receives from licensors on fixed fee contracts is recognized over the term in which we are providing services associated with the fixed fee contract. We recognize our administrative fees net of the consideration paid to the patent licensors in the pool as licensing revenue.
