Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1: Description of business

Background and nature of operations

DoubleDown Interactive Co., Ltd. (“DDI,” “we,” “us,” “our” or “the Company,”) was incorporated in 2008 in Seoul, Korea as an interactive entertainment studio, focused on the development and publishing of casual games and mobile applications. DDI is a subsidiary of DoubleU Games Co., Ltd. (“DUG” or “DoubleU Games”), a Korean company and our controlling shareholder holding 67.1% of our outstanding shares. The remaining 32.9% of our outstanding shares are held by STIC Special Situation Private Equity Fund (“STIC”, 20.2%) and the remainder by participants in our IPO (12.7%). In 2017, DDI acquired DoubleDown Interactive, LLC (“DDI-US”) from International Gaming Technologies (“IGT”) for approximately $825 million. DDI-US, with its principal place of business located in Seattle, Washington, is our primary revenue-generating entity.

We develop and publish digital gaming content on various mobile and web platforms through our multi-format interactive all-in-one game experience concept. We host DoubleDown Casino, DoubleDown Classic, DoubleDown Fort Knox and Undead World within various formats.

Initial Public Offering

On September 2, 2021, DoubleDown Interactive Co., Ltd. filed its initial public offering (the “Offering”) of 6,316,000 American Depositary Shares (the “ADSs”), each representing 0.05 common share, with par value of W10,000 per share, of the Company, at a price to the public of $18.00 per ADS, before underwriting discounts and commissions. The number of ADSs sold by the Company was 5,263,000, and the number of ADSs sold by STIC Special Situation Diamond Limited, the selling shareholder in the Offering (the “Selling Shareholder”), was 1,053,000. The net proceeds to us from this offering was approximately $86.0 million, after deducting the underwriting discounts and commissions and the offering expenses in the aggregate of approximately $8.7 million.

Prior to this offering, there has been no public market for our common shares or ADSs. Our ADSs trade on the NASDAQ Stock Market (“NASDAQ”) under the symbol “DDI.”

Basis of preparation and consolidation

Our unaudited condensed consolidated financial statements include all adjustments of a normal, recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim period presented are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements for the years ended December 31, 2021, 2020 and 2019.

The condensed consolidated financial statements include the balances and accounts of DDI and our controlled subsidiaries. All significant inter-company transactions, balances and unrealized gains or losses have been eliminated. We view our operations and manage our business as one operating segment.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires our management to make estimates and assumptions that affect financial statements and accompanying notes. We regularly evaluate estimates and assumptions related to provisions for income taxes, revenue recognition, expense accruals, deferred income tax asset valuation allowances, valuation of goodwill and intangibles, and legal contingencies. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources.

The actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to recent unrest in the eastern Europe region.

Functional currency and translation of financial statements

Our functional currency is the Korean Won (“KRW”) and the U.S. Dollar (“dollar,” “USD,” “US$,” or “$”) is the functional currency of our United States subsidiaries. The accompanying consolidated financial statements are presented in USD.

F-6

The consolidated balance sheets have been translated at the exchange rates prevailing at each balance sheet date. The consolidated statement of comprehensive income and statement of cash flows have been translated using the weighted-average exchange rates prevailing during the periods of each statement. The equity capital is denominated in the functional currency, KRW, and is translated at historical exchange rates. All translation adjustments resulting from translating into the reporting currency are accumulated as a separate component of accumulated other comprehensive income in shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income (expense).

Intercompany monetary items denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date with the gain or loss arising on translation recorded to other income (expense). Intercompany non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. When we parenthetically disclose USD amounts for certain financial instruments denominated in KRW for the benefit of the reader, we use the exchange rates in effect as of June 30, 2022, unless otherwise noted.

Financial instruments and concentration of credit risk

Financial instruments, which potentially expose us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable.

Accounts receivable are recorded and carried at the net invoiced amount, which is net of platform payment processing fees, unsecured, and represent amounts due to us based on contractual obligations where an executed contract exists. We do not require collateral and have not recognized an allowance as management estimates the net receivable is fully collectible. Apple, Inc. (“Apple”), Facebook, Inc. (“Facebook”), and Google, LLC (“Google”) represent significant distribution, marketing, and payment platforms for our games. A substantial portion of our revenue was generated from players who accessed our games through these platforms and a significant concentration of our accounts receivable balance is comprised of balances owed to us by these platforms.​​​​​​​

	Revenue Concentration
	Three months ended June 30,						Six Months ended June 30,
	2022			2021			2022			2021
Apple		54.5	%		50.5	%		54.3	%		50.9	%
Facebook		24.2	%		26.4	%		24.2	%		26.6	%
Google		18.6	%		19.6	%		18.7	%		19.3	%

The following table summarizes the percentage of revenues and accounts receivable generated via our platform providers in excess of 10% of our total revenues and total accounts receivable:​​​​​​​

	Accounts Receivable concentration
	As of June 30,			As of December 31,
	2022			2021
Apple		56.0	%		55.6	%
Facebook		22.6	%		23.7	%
Google		17.7	%		17.5	%

Note 2: Revenue from Contracts with Customers

Our social and mobile apps operate on a free-to-play model, whereby game players may collect virtual currency free of charge through the passage of time or through targeted marketing promotions. If a game player wishes to obtain virtual currency above and beyond the level of free virtual currency available to that player, the player may purchase additional virtual currency. Once a purchase is completed, the virtual currency is deposited into the player’s account and is not separately identifiable from previously purchased virtual currency or virtual currency obtained by the game player for free.

Once obtained, virtual currency (either free or purchased) cannot be redeemed for cash nor exchanged for anything other than gameplay within our apps. When virtual currency is played on any of our games, the game player could “win” and would be awarded additional virtual currency or could “lose” and lose the future use of that virtual currency. We have concluded that our virtual currency represents consumable goods, because the game player does not receive any additional benefit from the games and is not entitled to any additional rights once the virtual currency is substantially consumed.

F-7

Control transfers when the virtual currency is consumed for gameplay. We recognize revenue from player purchases of virtual currency based on the consumption of this currency. We determined through a review of play behavior that game players generally do not purchase additional virtual currency until their existing virtual currency balances, regardless of source (e.g., bonus currency, gifted currency through social media channels, daily free chips, etc.), have been substantially consumed.

Based on an analysis of customers’ historical play behavior, purchase behavior, and the amount of virtual currency outstanding, we are able to estimate the rate that virtual currency is consumed during gameplay. Accordingly, revenue is recognized using a user-based revenue model with the period between purchases representing the timing difference between virtual currency purchase and consumption. This timing difference is relatively short.

We continuously gather and analyze detailed customer play behavior and assess this data in relation to our judgments used for revenue recognition.

Disaggregation of revenue

We believe disaggregation of our revenue based on platform and geographical location are appropriate categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

The following table represents our disaggregation of revenue between mobile and web platforms (in thousands):

	Three months ended June 30,				Six Months ended June 30,
	2022		2021		2022		2021
Mobile	$	60,753	$	67,317	$	124,883	$	137,321
Web		19,817		25,911		41,173		52,574
Total	$	80,570	$	93,228	$	166,056	$	189,895

The following table presents our revenue disaggregated based on the geographical location of our players (in thousands):

	Three months ended June 30,				Six Months ended June 30,
	2022		2021		2022		2021
U.S. (1)	$	70,661	$	80,432	$	144,349	$	164,094
International		9,909		12,796		21,707		25,801
Total	$	80,570	$	93,228	$	166,056	$	189,895

(1) Geographic location is presented as being derived from the U.S. when data is not available

Contract assets, contract liabilities and other disclosures

Customer payments are based on the payment terms established in our contracts. Payments for purchase of virtual currency are required at time of purchase, are non-refundable and relate to non-cancellable contracts that specify our performance obligations. All payments are initially recorded as revenue, as the player has no right of return after the purchase, consistent with our standard terms and conditions. Based on our analysis, at each period end, we estimate the number of days to consume virtual currency. This represents the revenue amount where the performance obligation has not been met and is deferred as a contract liability until we satisfy the obligation. The contract asset consists of platform

F-8

fees for which revenue has not been recognized. For subscription revenue, the remaining portion of the daily ratable monthly subscription is recorded as a contract liability and the applicable platform fees as a contract asset.

The following table summarized our opening and closing balances in contract assets and contract liabilities (in thousands):

	As of June 30,		As of December 31,
	2022		2021
Contract assets (1)	$	484	$	674
Contract liabilities		1,612		2,246

(1) Contract assets are included within prepaid expenses and other assets in our consolidated balance sheet.

Note 3: Short-term investments

The Company holds investments in marketable securities with the intention of selling these investments within a relatively short period of time (3-6 months). At June 30, 2022, our investments were comprised of bonds held for trading purposes. As such, gains or losses from holding or trading these securities are recognized in the Statements of Income.

Note 4: Goodwill and intangible assets

There were no changes to the carrying amount of goodwill in the three months ended June 30, 2022.Changes in the carrying amount of intangible assets were as follows (in thousands):

		June 30, 2022							December 31, 2021

Note 6: Fair value measurements

The carrying values of our accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these instruments.

Our cash equivalents (Level 1 estimate) were comprised of money market funds totaling $192.5 million and short-term investments (a Level 2 estimate) were comprised of short-term bonds totaling $91.5 million as of June 30, 2022. As of December 31, 2021, our cash and cash equivalents totaled $242.1 million and consisted of money market and Korean market government bonds. We rely on credit market data to track interest rates for other entities with similar risk profiles.

As of June 30, 2022 and December 31, 2021, we believe the fair value of our senior notes (a Level 3 estimate) approximates carrying value due to the nature of the instruments and the lack of meaningful change to our credit profile.

Note 7: Income taxes

We are subject to federal and state income taxes in Korea and the United States. We account for our provision for income taxes in accordance with ASC 740, Income Taxes, which requires an estimate of the annual effective tax rate for the full year to be applied to the interim period, taking into account year-to-date amounts and projected results for the full year.

Our effective tax rate varies from the statutory Korean income tax rate due to the effect of foreign rate differential, withholding taxes, state and local income taxes, foreign derived intangible income (FDII) deduction, research and development credits, and a valuation allowance on Korean deferred tax assets. Our effective tax rate could fluctuate significantly from quarter to quarter based on variations in the estimated and actual level of pre-tax income or loss by jurisdiction, changes in enacted tax laws and regulations, and changes in estimates regarding non-deductible expenses and tax credits. As of June 30, 2022, and December 31, 2021, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are more likely than not to be realized.

The income tax benefit of $12.0 million for the three months ended June 30, 2022, reflects an effective tax rate of 26.1%, which is higher than the effective tax rate of 13.3% for the three months ended June 30, 2021. The increase in rate from 2021 to 2022 is primarily due to an increase in the state effective tax rate in 2022 and a discrete valuation allowance release on Korean tax attributes of $2.7 million in 2021.

The income tax benefit of $6.0 million for six months ended June 30, 2022, reflects an effective tax rate of 27.8%, which is higher than the effective tax rate of 20.1% for the six months ended June 30, 2021. The increase in rate from 2021 to 2022 is primarily due to an increase in the state effective tax rate in 2022 and a discrete valuation allowance release on Korean tax attributes of $2.7 million in 2021.

Note 8: Net Income per share

Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net income per share is computed by dividing net income by the weighted-average number of common shares and dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. There were no potentially dilutive securities outstanding in either period presented.

Note 9: Leases

We are lessee for corporate office space in Seattle, Washington and Seoul, Korea. The lessor for our Seoul, Korea leases is our parent, DoubleU Games (see Note 11). Our leases have remaining terms of fifteen to twenty eight months. We do not have any finance leases. Our total variable and short-term lease payments are immaterial for all periods presented.

The Seattle, Washington lease originated in July 2012 and consists of 49,375 square feet. The lease will expire in October 2024.

In February 2019, we executed new subleases with our parent, DUG, for 21,218 square feet of office space in Gangnam-gu, Seoul, Korea. The lease term will expire in September 2023.

Note 11: Commitments and contingencies

Legal contingencies

On April 12, 2018, a class-action lawsuit was filed against DDI-US demanding a return of unfair benefit under the pretext that the Company’s social casino games are not legal in the State of Washington, United States. Similar class-action lawsuits were concurrently filed with certain of our competitors, certain of which, announced settlements which the court has recently approved.

In August 2018, we filed a Motion to Compel Arbitration, which was denied and immediately appealed in December 2018. We were granted a Motion to Stay pending appeal in February 2019. In October 2019, a court date was issued and subsequently abated as the Ninth Circuit Appeals court hears the oral arguments and a resolution of appeal is determined in a similar case with one of our competitors. On January 29, 2020, the Ninth Circuit affirmed the District Court’s denial of arbitration, thereby denying our appeal to compel arbitration. The case is now in District Court. On June 17, 2020, we filed a motion in the United States District Court for the Western District of Washington, which, if granted, would certify certain questions of state law to the Washington State Supreme Court for interpretation in accordance with applicable state law. On August 11, 2020, the District Court denied DDI-US’s motion to certify certain questions to the Washington State Supreme Court. We subsequently filed a motion for reconsideration of this ruling. On August 13, 2020, DDI-US filed a motion to strike the plaintiffs’ nationwide class allegations, which was noted for consideration on October 2, 2020. On September 10, 2020, DDI-US filed a motion to dismiss under Fed. R. Civ P. 12 (B)(1) and a motion to abstain asking the District Court to stay this lawsuit pending the resolution of a Declaratory Judgment action filed by DDI-US (and IGT) in the Washington State Superior Court seeking a ruling on certain relevant issues under Washington state law, which was noted for consideration on October 2, 2020. No date for a hearing on these motions has been set. Additional discovery has continued, including but not limited to, our issuance of discovery to plaintiffs. On January 15, 2021, our motion for reconsideration was denied. On February 25, 2021, plaintiffs filed a motion for class certification and for preliminary injunction. On March 19, 2021, our motion to strike the nationwide class allegations was denied. Discovery in the federal court case has commenced and is continuing. On April 25, 2021, plaintiffs filed their Second Amended Complaint, changing their allegations to include an additional corporate entity of co-defendant, IGT. DDI-US served plaintiffs with its expert disclosures and filed an Opposition to Plaintiffs’ Motion for Class Certification and Preliminary Injunction on May 11, 2021. On June 29, 2021, the court denied the Company’s motion for the certification of an interlocutory appeal from the court’s order denying the Company’s Motion to Strike Nationwide Class Action Allegations. On July 9, 2021, Double Down moved for relief from the upcoming settlement deadline and dispositive motions deadline. On July 19, 2021, the court extended the discovery completion and settlement conference deadlines to August 24, 2021 and September 7, 2021, respectively, and struck all subsequent case management deadlines, including the dispositive motion deadline and the trial date. The court stated in its July 19, 2021 order that it would reset case management deadlines after various motions, including plaintiffs’ motion for class certification and preliminary injunction, and Double Down’s renewed motion to stay pending arbitration, have been decided. On August 19, 2021, plaintiffs filed a motion for sanctions and request for evidentiary hearing, regarding alleged spoliation of electronic documents by Double Down. Double Down disputes the allegations and has responded. The parties have filed various other motions and engaged in discovery, including depositions and expert discovery. No trial date has been set at this time. We dispute any allegation of wrongdoing and will continue to vigorously defend ourselves in this matter.

IGT tendered its defense of the lawsuit to Double Down and sought indemnity for any damages from the lawsuit, based on various agreements associated with IGT’s sale of Double Down. Double Down had previously tendered its defense to IGT and sought indemnity from it. The parties entered into a standstill or tolling agreement, which expired on September 1, 2021, and was extended by agreement until October 1, 2021. On December 20, 2021, IGT submitted a demand for mediation to Double Down. On June 16, June 24, and July 5, the parties or the plaintiffs moved for stays.

The case is subject to significant uncertainties. In determining the likelihood of a loss and/or the measurement of any loss or range of loss, we evaluated (1) the facts and circumstances known to us, including information regarding the likelihood of a settlement and the outcome of discussions relating to indemnification by co-defendants, (2) the current state of the proceedings, including outstanding motions for certification of a class, or denial thereof, and other relevant events and developments, (3) the advice and analyses of counsel and other advisors, and (4) the assumptions and judgment of management, all of which involve a series of complex judgments about potential future events with multiple outcomes. In accordance with ASC 450-20, the Company established an accrual for this loss contingency of $3.5 million during 2021. In Q2 2022, as a result of ongoing discussions with the parties to these matters, including non-binding mediation, the Company recorded an additional charge of $71.5 million, which was included in General and Administrative expenses, reflecting an increase in the low end of the reasonably possible range of loss of $75 million to

F-12

$201.5 million associated with legal proceedings. The Company will continue to evaluate the appropriateness of the amount recorded as the litigation proceeds over time, potentially resulting in a material adjustment thereto.

NEXRF brought suit alleging patent infringement of certain patents for gaming applications used by defendants. Davis Wright Tremaine LLP represents all three defendants. The defendants were served with the lawsuit on January 8, 2021. The defendants filed a motion to dismiss plaintiffs’ complaint on April 29, 2021, arguing that the asserted patents are not patent-eligible because they are drawn to an abstract idea. The defendants also filed a motion to stay discovery pending resolution of the motion to dismiss. During the pendency of the defendants’ motions, however, a federal court in Nevada issued an order invalidating the asserted patents on the basis of patent ineligibility. NEXRF appealed this ruling to the Federal Circuit, and the Federal Circuit affirmed the Nevada court’s invalidity finding. Due to the invalidation of the patents-in-suit, NEXRF agreed to dismiss the lawsuit against the DoubleDown entities. On July 26, 2022, the court entered dismissal of the DoubleDown entities with prejudice. The case is concluded.

Publishing and license agreements

DoubleU Games

We entered into the DoubleU Games License Agreement on March 7, 2018, and it was subsequently amended on July 1, 2019 and November 27, 2019. Pursuant to the DoubleU Games License Agreement, DoubleU Games grants us an exclusive license to develop and distribute certain DoubleU Games social casino game titles and sequels thereto in the social online game field of use. We are obligated to pay a royalty license fee to DoubleU Games in connection with these rights, with certain customary terms and conditions. The agreement remains in effect until either DUG no longer holds an interest, directly or indirectly, in DDI, or DDI no longer holds an interest, directly or indirectly, in DDI-US. In such event, the agreement provides that the parties will mutually renegotiate the terms of the agreement. As of June 30, 2022, we licensed approximately 57 game titles under the terms of this agreement.

International Gaming Technologies (“IGT”)

In 2017, we entered into a Game Development, Distribution, and Services agreement with IGT, and it was subsequently amended on January 1, 2019. Under the terms of the agreement, IGT will deliver game assets so that we can port (a process of converting the assets into functioning slot games by platform) the technology for inclusion in our gaming apps. The agreement includes game assets that are used to create new games. Under the agreement, we pay IGT a royalty rate of 7.5% of revenue for their proprietary assets and 15% of revenue for third-party game asset types. We also pay a monthly fee for porting. The initial term of the agreement is ten (10) years with up to two additional five-year periods. Costs incurred in connection with this agreement for the three months ended June 30, 2022 and 2021 totaled $2.3 million and $3.0 million, respectively, and are recognized as a component of cost of revenue, and six months ended June 30, 2022 and 2021 totaled $5.0 million and $6.0 million, respectively, and are recognized as a component of cost of revenue

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of business

Note 1: Description of business

Background and nature of operations

DoubleDown Interactive Co., Ltd. (“DDI,” “we,” “us,” “our” or “the Company,”) was incorporated in 2008 in Seoul, Korea as an interactive entertainment studio, focused on the development and publishing of casual games and mobile applications. DDI is a subsidiary of DoubleU Games Co., Ltd. (“DUG” or “DoubleU Games”), a Korean company and our controlling shareholder holding 67.1% of our outstanding shares. The remaining 32.9% of our outstanding shares are held by STIC Special Situation Private Equity Fund (“STIC”, 20.2%) and the remainder by participants in our IPO (12.7%). In 2017, DDI acquired DoubleDown Interactive, LLC (“DDI-US”) from International Gaming Technologies (“IGT”) for approximately $825 million. DDI-US, with its principal place of business located in Seattle, Washington, is our primary revenue-generating entity.

We develop and publish digital gaming content on various mobile and web platforms through our multi-format interactive all-in-one game experience concept. We host DoubleDown Casino, DoubleDown Classic, DoubleDown Fort Knox and Undead World within various formats.

Initial Public Offering

On September 2, 2021, DoubleDown Interactive Co., Ltd. filed its initial public offering (the “Offering”) of 6,316,000 American Depositary Shares (the “ADSs”), each representing 0.05 common share, with par value of W10,000 per share, of the Company, at a price to the public of $18.00 per ADS, before underwriting discounts and commissions. The number of ADSs sold by the Company was 5,263,000, and the number of ADSs sold by STIC Special Situation Diamond Limited, the selling shareholder in the Offering (the “Selling Shareholder”), was 1,053,000. The net proceeds to us from this offering was approximately $86.0 million, after deducting the underwriting discounts and commissions and the offering expenses in the aggregate of approximately $8.7 million.

Prior to this offering, there has been no public market for our common shares or ADSs. Our ADSs trade on the NASDAQ Stock Market (“NASDAQ”) under the symbol “DDI.”

Basis of preparation and consolidation

Our unaudited condensed consolidated financial statements include all adjustments of a normal, recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim period presented are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements for the years ended December 31, 2021, 2020 and 2019.

The condensed consolidated financial statements include the balances and accounts of DDI and our controlled subsidiaries. All significant inter-company transactions, balances and unrealized gains or losses have been eliminated. We view our operations and manage our business as one operating segment.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires our management to make estimates and assumptions that affect financial statements and accompanying notes. We regularly evaluate estimates and assumptions related to provisions for income taxes, revenue recognition, expense accruals, deferred income tax asset valuation allowances, valuation of goodwill and intangibles, and legal contingencies. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources.

The actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to recent unrest in the eastern Europe region.

Functional currency and translation of financial statements

Our functional currency is the Korean Won (“KRW”) and the U.S. Dollar (“dollar,” “USD,” “US$,” or “$”) is the functional currency of our United States subsidiaries. The accompanying consolidated financial statements are presented in USD.

The consolidated balance sheets have been translated at the exchange rates prevailing at each balance sheet date. The consolidated statement of comprehensive income and statement of cash flows have been translated using the weighted-average exchange rates prevailing during the periods of each statement. The equity capital is denominated in the functional currency, KRW, and is translated at historical exchange rates. All translation adjustments resulting from translating into the reporting currency are accumulated as a separate component of accumulated other comprehensive income in shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income (expense).

Intercompany monetary items denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date with the gain or loss arising on translation recorded to other income (expense). Intercompany non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. When we parenthetically disclose USD amounts for certain financial instruments denominated in KRW for the benefit of the reader, we use the exchange rates in effect as of June 30, 2022, unless otherwise noted.

Financial instruments and concentration of credit risk

Financial instruments, which potentially expose us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable.

Accounts receivable are recorded and carried at the net invoiced amount, which is net of platform payment processing fees, unsecured, and represent amounts due to us based on contractual obligations where an executed contract exists. We do not require collateral and have not recognized an allowance as management estimates the net receivable is fully collectible. Apple, Inc. (“Apple”), Facebook, Inc. (“Facebook”), and Google, LLC (“Google”) represent significant distribution, marketing, and payment platforms for our games. A substantial portion of our revenue was generated from players who accessed our games through these platforms and a significant concentration of our accounts receivable balance is comprised of balances owed to us by these platforms.​​​​​​​

	Revenue Concentration

Revenue from Contracts with Customers

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Note 2: Revenue from Contracts with Customers

Our social and mobile apps operate on a free-to-play model, whereby game players may collect virtual currency free of charge through the passage of time or through targeted marketing promotions. If a game player wishes to obtain virtual currency above and beyond the level of free virtual currency available to that player, the player may purchase additional virtual currency. Once a purchase is completed, the virtual currency is deposited into the player’s account and is not separately identifiable from previously purchased virtual currency or virtual currency obtained by the game player for free.

Once obtained, virtual currency (either free or purchased) cannot be redeemed for cash nor exchanged for anything other than gameplay within our apps. When virtual currency is played on any of our games, the game player could “win” and would be awarded additional virtual currency or could “lose” and lose the future use of that virtual currency. We have concluded that our virtual currency represents consumable goods, because the game player does not receive any additional benefit from the games and is not entitled to any additional rights once the virtual currency is substantially consumed.

Control transfers when the virtual currency is consumed for gameplay. We recognize revenue from player purchases of virtual currency based on the consumption of this currency. We determined through a review of play behavior that game players generally do not purchase additional virtual currency until their existing virtual currency balances, regardless of source (e.g., bonus currency, gifted currency through social media channels, daily free chips, etc.), have been substantially consumed.

Based on an analysis of customers’ historical play behavior, purchase behavior, and the amount of virtual currency outstanding, we are able to estimate the rate that virtual currency is consumed during gameplay. Accordingly, revenue is recognized using a user-based revenue model with the period between purchases representing the timing difference between virtual currency purchase and consumption. This timing difference is relatively short.

We continuously gather and analyze detailed customer play behavior and assess this data in relation to our judgments used for revenue recognition.

Disaggregation of revenue

We believe disaggregation of our revenue based on platform and geographical location are appropriate categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

The following table represents our disaggregation of revenue between mobile and web platforms (in thousands):

	Three months ended June 30,				Six Months ended June 30,

(1) Geographic location is presented as being derived from the U.S. when data is not available

Contract assets, contract liabilities and other disclosures

Customer payments are based on the payment terms established in our contracts. Payments for purchase of virtual currency are required at time of purchase, are non-refundable and relate to non-cancellable contracts that specify our performance obligations. All payments are initially recorded as revenue, as the player has no right of return after the purchase, consistent with our standard terms and conditions. Based on our analysis, at each period end, we estimate the number of days to consume virtual currency. This represents the revenue amount where the performance obligation has not been met and is deferred as a contract liability until we satisfy the obligation. The contract asset consists of platform

fees for which revenue has not been recognized. For subscription revenue, the remaining portion of the daily ratable monthly subscription is recorded as a contract liability and the applicable platform fees as a contract asset.

The following table summarized our opening and closing balances in contract assets and contract liabilities (in thousands):

	As of June 30,		As of December 31,
	2022		2021
Contract assets (1)	$	484	$	674

Fair Value Disclosures [Abstract]

Fair value measurements

Note 6: Fair value measurements

The carrying values of our accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these instruments.

Our cash equivalents (Level 1 estimate) were comprised of money market funds totaling $192.5 million and short-term investments (a Level 2 estimate) were comprised of short-term bonds totaling $91.5 million as of June 30, 2022. As of December 31, 2021, our cash and cash equivalents totaled $242.1 million and consisted of money market and Korean market government bonds. We rely on credit market data to track interest rates for other entities with similar risk profiles.

As of June 30, 2022 and December 31, 2021, we believe the fair value of our senior notes (a Level 3 estimate) approximates carrying value due to the nature of the instruments and the lack of meaningful change to our credit profile.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Note 7: Income taxes

We are subject to federal and state income taxes in Korea and the United States. We account for our provision for income taxes in accordance with ASC 740, Income Taxes, which requires an estimate of the annual effective tax rate for the full year to be applied to the interim period, taking into account year-to-date amounts and projected results for the full year.

Our effective tax rate varies from the statutory Korean income tax rate due to the effect of foreign rate differential, withholding taxes, state and local income taxes, foreign derived intangible income (FDII) deduction, research and development credits, and a valuation allowance on Korean deferred tax assets. Our effective tax rate could fluctuate significantly from quarter to quarter based on variations in the estimated and actual level of pre-tax income or loss by jurisdiction, changes in enacted tax laws and regulations, and changes in estimates regarding non-deductible expenses and tax credits. As of June 30, 2022, and December 31, 2021, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are more likely than not to be realized.

The income tax benefit of $12.0 million for the three months ended June 30, 2022, reflects an effective tax rate of 26.1%, which is higher than the effective tax rate of 13.3% for the three months ended June 30, 2021. The increase in rate from 2021 to 2022 is primarily due to an increase in the state effective tax rate in 2022 and a discrete valuation allowance release on Korean tax attributes of $2.7 million in 2021.

The income tax benefit of $6.0 million for six months ended June 30, 2022, reflects an effective tax rate of 27.8%, which is higher than the effective tax rate of 20.1% for the six months ended June 30, 2021. The increase in rate from 2021 to 2022 is primarily due to an increase in the state effective tax rate in 2022 and a discrete valuation allowance release on Korean tax attributes of $2.7 million in 2021.

Note 11: Commitments and contingencies

Legal contingencies

On April 12, 2018, a class-action lawsuit was filed against DDI-US demanding a return of unfair benefit under the pretext that the Company’s social casino games are not legal in the State of Washington, United States. Similar class-action lawsuits were concurrently filed with certain of our competitors, certain of which, announced settlements which the court has recently approved.

In August 2018, we filed a Motion to Compel Arbitration, which was denied and immediately appealed in December 2018. We were granted a Motion to Stay pending appeal in February 2019. In October 2019, a court date was issued and subsequently abated as the Ninth Circuit Appeals court hears the oral arguments and a resolution of appeal is determined in a similar case with one of our competitors. On January 29, 2020, the Ninth Circuit affirmed the District Court’s denial of arbitration, thereby denying our appeal to compel arbitration. The case is now in District Court. On June 17, 2020, we filed a motion in the United States District Court for the Western District of Washington, which, if granted, would certify certain questions of state law to the Washington State Supreme Court for interpretation in accordance with applicable state law. On August 11, 2020, the District Court denied DDI-US’s motion to certify certain questions to the Washington State Supreme Court. We subsequently filed a motion for reconsideration of this ruling. On August 13, 2020, DDI-US filed a motion to strike the plaintiffs’ nationwide class allegations, which was noted for consideration on October 2, 2020. On September 10, 2020, DDI-US filed a motion to dismiss under Fed. R. Civ P. 12 (B)(1) and a motion to abstain asking the District Court to stay this lawsuit pending the resolution of a Declaratory Judgment action filed by DDI-US (and IGT) in the Washington State Superior Court seeking a ruling on certain relevant issues under Washington state law, which was noted for consideration on October 2, 2020. No date for a hearing on these motions has been set. Additional discovery has continued, including but not limited to, our issuance of discovery to plaintiffs. On January 15, 2021, our motion for reconsideration was denied. On February 25, 2021, plaintiffs filed a motion for class certification and for preliminary injunction. On March 19, 2021, our motion to strike the nationwide class allegations was denied. Discovery in the federal court case has commenced and is continuing. On April 25, 2021, plaintiffs filed their Second Amended Complaint, changing their allegations to include an additional corporate entity of co-defendant, IGT. DDI-US served plaintiffs with its expert disclosures and filed an Opposition to Plaintiffs’ Motion for Class Certification and Preliminary Injunction on May 11, 2021. On June 29, 2021, the court denied the Company’s motion for the certification of an interlocutory appeal from the court’s order denying the Company’s Motion to Strike Nationwide Class Action Allegations. On July 9, 2021, Double Down moved for relief from the upcoming settlement deadline and dispositive motions deadline. On July 19, 2021, the court extended the discovery completion and settlement conference deadlines to August 24, 2021 and September 7, 2021, respectively, and struck all subsequent case management deadlines, including the dispositive motion deadline and the trial date. The court stated in its July 19, 2021 order that it would reset case management deadlines after various motions, including plaintiffs’ motion for class certification and preliminary injunction, and Double Down’s renewed motion to stay pending arbitration, have been decided. On August 19, 2021, plaintiffs filed a motion for sanctions and request for evidentiary hearing, regarding alleged spoliation of electronic documents by Double Down. Double Down disputes the allegations and has responded. The parties have filed various other motions and engaged in discovery, including depositions and expert discovery. No trial date has been set at this time. We dispute any allegation of wrongdoing and will continue to vigorously defend ourselves in this matter.

IGT tendered its defense of the lawsuit to Double Down and sought indemnity for any damages from the lawsuit, based on various agreements associated with IGT’s sale of Double Down. Double Down had previously tendered its defense to IGT and sought indemnity from it. The parties entered into a standstill or tolling agreement, which expired on September 1, 2021, and was extended by agreement until October 1, 2021. On December 20, 2021, IGT submitted a demand for mediation to Double Down. On June 16, June 24, and July 5, the parties or the plaintiffs moved for stays.

The case is subject to significant uncertainties. In determining the likelihood of a loss and/or the measurement of any loss or range of loss, we evaluated (1) the facts and circumstances known to us, including information regarding the likelihood of a settlement and the outcome of discussions relating to indemnification by co-defendants, (2) the current state of the proceedings, including outstanding motions for certification of a class, or denial thereof, and other relevant events and developments, (3) the advice and analyses of counsel and other advisors, and (4) the assumptions and judgment of management, all of which involve a series of complex judgments about potential future events with multiple outcomes. In accordance with ASC 450-20, the Company established an accrual for this loss contingency of $3.5 million during 2021. In Q2 2022, as a result of ongoing discussions with the parties to these matters, including non-binding mediation, the Company recorded an additional charge of $71.5 million, which was included in General and Administrative expenses, reflecting an increase in the low end of the reasonably possible range of loss of $75 million to

$201.5 million associated with legal proceedings. The Company will continue to evaluate the appropriateness of the amount recorded as the litigation proceeds over time, potentially resulting in a material adjustment thereto.

NEXRF brought suit alleging patent infringement of certain patents for gaming applications used by defendants. Davis Wright Tremaine LLP represents all three defendants. The defendants were served with the lawsuit on January 8, 2021. The defendants filed a motion to dismiss plaintiffs’ complaint on April 29, 2021, arguing that the asserted patents are not patent-eligible because they are drawn to an abstract idea. The defendants also filed a motion to stay discovery pending resolution of the motion to dismiss. During the pendency of the defendants’ motions, however, a federal court in Nevada issued an order invalidating the asserted patents on the basis of patent ineligibility. NEXRF appealed this ruling to the Federal Circuit, and the Federal Circuit affirmed the Nevada court’s invalidity finding. Due to the invalidation of the patents-in-suit, NEXRF agreed to dismiss the lawsuit against the DoubleDown entities. On July 26, 2022, the court entered dismissal of the DoubleDown entities with prejudice. The case is concluded.

Publishing and license agreements

DoubleU Games

We entered into the DoubleU Games License Agreement on March 7, 2018, and it was subsequently amended on July 1, 2019 and November 27, 2019. Pursuant to the DoubleU Games License Agreement, DoubleU Games grants us an exclusive license to develop and distribute certain DoubleU Games social casino game titles and sequels thereto in the social online game field of use. We are obligated to pay a royalty license fee to DoubleU Games in connection with these rights, with certain customary terms and conditions. The agreement remains in effect until either DUG no longer holds an interest, directly or indirectly, in DDI, or DDI no longer holds an interest, directly or indirectly, in DDI-US. In such event, the agreement provides that the parties will mutually renegotiate the terms of the agreement. As of June 30, 2022, we licensed approximately 57 game titles under the terms of this agreement.

International Gaming Technologies (“IGT”)

In 2017, we entered into a Game Development, Distribution, and Services agreement with IGT, and it was subsequently amended on January 1, 2019. Under the terms of the agreement, IGT will deliver game assets so that we can port (a process of converting the assets into functioning slot games by platform) the technology for inclusion in our gaming apps. The agreement includes game assets that are used to create new games. Under the agreement, we pay IGT a royalty rate of 7.5% of revenue for their proprietary assets and 15% of revenue for third-party game asset types. We also pay a monthly fee for porting. The initial term of the agreement is ten (10) years with up to two additional five-year periods. Costs incurred in connection with this agreement for the three months ended June 30, 2022 and 2021 totaled $2.3 million and $3.0 million, respectively, and are recognized as a component of cost of revenue, and six months ended June 30, 2022 and 2021 totaled $5.0 million and $6.0 million, respectively, and are recognized as a component of cost of revenue

Accounting Policies [Abstract]

Basis of preparation and consolidation

Basis of preparation and consolidation

Our unaudited condensed consolidated financial statements include all adjustments of a normal, recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim period presented are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements for the years ended December 31, 2021, 2020 and 2019.

The condensed consolidated financial statements include the balances and accounts of DDI and our controlled subsidiaries. All significant inter-company transactions, balances and unrealized gains or losses have been eliminated. We view our operations and manage our business as one operating segment.

Use of estimates

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires our management to make estimates and assumptions that affect financial statements and accompanying notes. We regularly evaluate estimates and assumptions related to provisions for income taxes, revenue recognition, expense accruals, deferred income tax asset valuation allowances, valuation of goodwill and intangibles, and legal contingencies. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources.

The actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to recent unrest in the eastern Europe region.

Functional currency and translation of financial statements

Functional currency and translation of financial statements

Our functional currency is the Korean Won (“KRW”) and the U.S. Dollar (“dollar,” “USD,” “US$,” or “$”) is the functional currency of our United States subsidiaries. The accompanying consolidated financial statements are presented in USD.

The consolidated balance sheets have been translated at the exchange rates prevailing at each balance sheet date. The consolidated statement of comprehensive income and statement of cash flows have been translated using the weighted-average exchange rates prevailing during the periods of each statement. The equity capital is denominated in the functional currency, KRW, and is translated at historical exchange rates. All translation adjustments resulting from translating into the reporting currency are accumulated as a separate component of accumulated other comprehensive income in shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income (expense).

Intercompany monetary items denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date with the gain or loss arising on translation recorded to other income (expense). Intercompany non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. When we parenthetically disclose USD amounts for certain financial instruments denominated in KRW for the benefit of the reader, we use the exchange rates in effect as of June 30, 2022, unless otherwise noted.

Financial instruments and concentration of credit risk

Financial instruments and concentration of credit risk

Financial instruments, which potentially expose us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable.

Accounts receivable are recorded and carried at the net invoiced amount, which is net of platform payment processing fees, unsecured, and represent amounts due to us based on contractual obligations where an executed contract exists. We do not require collateral and have not recognized an allowance as management estimates the net receivable is fully collectible. Apple, Inc. (“Apple”), Facebook, Inc. (“Facebook”), and Google, LLC (“Google”) represent significant distribution, marketing, and payment platforms for our games. A substantial portion of our revenue was generated from players who accessed our games through these platforms and a significant concentration of our accounts receivable balance is comprised of balances owed to us by these platforms.​​​​​​​
