2. Revenue from Contracts with Customers

On January 1, 2018, we adopted ASC Topic 606 using the modified retrospective transition method applied to contracts that were not complete as of the adoption date. Consolidated financial results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while prior period amounts continue to be reported in accordance with ASC Topic 605, “Revenue Recognition”.

As of January 1, 2018, we recorded a net reduction of $4.0 million to our opening deferred revenue and accumulated deficit balances, net of tax, due to the cumulative impact of adopting ASC Topic 606. The impact was driven by the recognition of revenue for certain advertising arrangements for which revenue was not previously recognized until payment was certain, partially offset by the deferral of previously recognized revenue for a symbolic license arrangement, for which revenue is recognized over the term of the license under ASC Topic 606.

The impact of adopting ASC Topic 606 on our consolidated balance sheet as of June 30, 2018 was as follows (in thousands):

	As of June 30, 2018
	Amounts as Reported			Amounts without Adoption of ASC Topic 606			Increase (Decrease) from ASC Topic 606 Adoption
Current liabilities:
Deferred revenue	$	156,316		$	164,930		$	(8,614	)
Total current liabilities		269,683			278,297			(8,614	)
Deferred revenue		2,359			1,708			651
Total liabilities		386,279			394,242			(7,963	)
Accumulated deficit		(1,762,437	)		(1,770,400	)		7,963

Total liabilities and stockholders' equity	$	1,985,873		$	1,985,873		$	—

As a result of adopting ASC Topic 606, deferred revenue as of June 30, 2018 decreased from certain advertising arrangements for which revenue would otherwise not be recognized until payment was certain under ASC Topic 605, partially offset by an increase to deferred revenue associated with the deferral of previously recognized revenue from the aforementioned symbolic license arrangement. The increase to our accumulated deficit as of June 30, 2018 from adopting ASC Topic 606 is the result of the net income impact discussed below and the $4.0 million transition adjustment recognized upon adoption of ASC Topic 606 on January 1, 2018.

The impact of adopting ASC Topic 606 on our consolidated statement of operations three and six months ended June 30, 2018 was as follows (in thousands):

	Three Months Ended June 30, 2018
	Amounts as Reported			Amounts without Adoption of ASC Topic 606			Increase (Decrease) from ASC Topic 606 Adoption
Revenue:

Revenue:

Total revenue		425,277		421,337			3,940
Income (loss) from operations		1,271		(2,669	)		3,940
Income (loss) before taxes		10,887		6,947			3,940

Net income (loss) per share attributable to common stockholders:
Basic	$	0.01	$	0.00		$	0.01
Diluted	$	0.01	$	0.00		$	0.01

As a result of adopting ASC Topic 606 during the three and six months ended June 30, 2018, advertising and other revenue increased primarily as a result of the aforementioned recognition of revenue for certain advertising arrangements for which revenue would otherwise not be recognized until payment was certain under ASC Topic 605 and the recognition of revenue over time from the symbolic license. There was no impact to net cash flows provided by (used in) operating, investing or financing activities for the six months ended June 30, 2018 as a result of adopting ASC Topic 606. However, within cash flows from operating activities, net income (loss) is $3.9 million higher and the change in deferred revenue is $3.9 million lower as a result of adopting ASC Topic 606 during the six months ended June 30, 2018.

Contract Balances

We receive payments from our customers based on the payment terms established in our contracts. Payments for online game revenue are required at time of purchase, are non-refundable and relate to non-cancellable contracts that specify our performance obligations. Such payments are initially recorded to deferred revenue, as the player has no right of return after the purchase, consistent with our standard terms of service. Deferred revenue is recognized into revenue as we satisfy our performance obligations.

Payments for advertising arrangements are due based on the contractually stated payment terms. For advertising arrangements, the contract terms generally require payment within 30 to 60 days subsequent to the end of the month. Our right to payment from the customer is unconditional and therefore recorded as accounts receivable.

During the three and six months ended June 30, 2018, we recognized $34.6 million and $118.2 million, respectively, of revenue that was included in the current deferred revenue balance on January 1, 2018.

The decrease in accounts receivable, net during the six months ended June 30, 2018 was primarily driven by cash collections of current period and previously due amounts exceeding sales on account during the period, partially offset by an increase in accounts receivable of $10.7 million from our acquisition of Gram Games Teknoloji A.S (“Gram Games”) during the second quarter of 2018. The increase in deferred revenue during the six months ended June 30, 2018 was primarily driven by the sale of virtual items during the period, which includes contribution from Gram Games, exceeding revenue recognized from the satisfaction of our performance obligations.

Unsatisfied Performance Obligations

Substantially all of our unsatisfied performance obligations relate to contracts with an original expected length of one year or less.
