_____________

( 1 ) 2017 amounts have not been adjusted under the modified retrospective method.

The Company generates revenue primarily from product sales, which include assembled and tested integrated circuits, as well as dies in wafer form. The Company also generates royalty revenue from licensing arrangements and revenue from wafer testing services performed for 

third

 parties, which have 

not

 been significant in all periods presented.

The Company sells its products primarily through 

third

-party distributors, value-added resellers, original equipment manufacturers, original design manufacturers and electronic manufacturing service providers. For the 

three

months ended 

June 30, 2018 

and 

2017,

 approximately 

86%

and

88%,

respectively, of the Company’s sales were made through distribution arrangements. For the 

six

months ended 

June 30, 2018 

and 

2017,

 approximately 

87%

and

88%,

respectively, of the Company’s sales were made through distribution arrangements. These distribution arrangements contain enforceable rights and obligations specific to those distributors and 

not

 the end customers. Purchase orders, which are governed by sales agreements or the Company's standard terms of sale, state the final terms for unit price, quantity, shipping and payment agreed by both parties. The Company considers purchase orders to be the contracts with customers. The unit price as stated on the purchase orders is considered the observable, stand-alone selling price for the arrangements.

Under Topic 

606,

 the Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods or services to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company excludes taxes assessed by government authorities, such as sales taxes, from revenue.

Product sales consist of a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue from distributors and direct end customers when the following events have occurred: (a) the Company has transferred physical possession of the products, (b) the Company has a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. In accordance with the shipping terms specified in the contracts, these criteria are generally met when the products are shipped from the Company’s facilities (such as the “Ex Works” shipping term) or delivered to the customers’ locations (such as the “Delivered Duty Paid” shipping term).

Under certain consignment agreements, revenue is 

not

 recognized when the products are held at customers’ designated locations because the Company retains ownership and the customers do 

not

 have an unconditional obligation to pay. The Company recognizes revenue when the customers pull the products from the locations or after a 

60

-day period lapses, at which time control transfers to the customers and the Company invoices them for payment.

Variable Consideration

The Company records variable consideration as a reduction to revenue in the same period the revenue is recognized. Three U.S.-based distributors have price adjustment rights when they sell the Company’s products to their end customers at a price that is lower than the distribution price invoiced by the Company. When the Company receives claims from the distributors that products have been sold to the end customers at the lower price, the Company issues the distributors credit memos for the price adjustments. The Company estimates the price adjustments based on analyses of historical claims, at both the distributor and product level, as well as an assessment of any known trends of product sales mix. Other U.S. distributors and non-U.S. distributors, which make up the majority of the Company’s total sales to distributors, do 

not

 have price adjustment rights.

In addition, certain distributors have limited stock rotation rights that permit the return of a small percentage of the previous 

six

 months’ purchases. The Company estimates the stock rotation returns based on analyses of historical returns, and the current level of inventory in the distribution channel.  The Company recognizes an asset for product returns which represents the right to recover products from the customers related to stock rotations, with a corresponding reduction to cost of goods sold.

Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. As of 

June 30, 2018 

and 

December 31, 2017, 

accounts receivable totaled 

$53.5

 million and 

$38.0

 million, respectively. To manage credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company did 

not

 recognize any impairment losses related to its receivables in any of the periods presented.

For certain customers located in Asia, the Company requires cash payments 

two

 weeks before the products are scheduled to be shipped to the customers. The Company records these payments received in advance of performance as customer prepayments within current accrued liabilities. As of 

June 30, 2018 

and 

December 31, 2017, 

customer prepayments totaled 

$3.2

 million and 

$4.7

 million, respectively. The decrease in the customer prepayment balance for the 

six

 months ended 

June 30, 2018 

resulted from a decrease in unfulfilled customer orders for which the Company has received payments. For the 

six

 months ended 

June 30, 2018, 

the Company recognized 

$4.7

 million of revenue that was included in the customer prepayment balance as of 

December 31, 2017.

Contract Costs

The Company pays sales commissions based on the achievement of pre-determined product sales targets. As the Company recognizes product sales at a point in time, sales commissions are expensed as incurred.

Warranty

The Company generally provides 

one

 to 

two

-year warranties against defects in materials and workmanship and will either repair the products, provide replacements at 

no

 charge to customers or issue a refund. As they are considered assurance-type warranties, the Company does 

not

 account for them as separate performance obligations. Warranty reserve requirements are based on a specific assessment of the products sold with warranties when a customer asserts a claim for warranty or a product defect. 

Practical Expedients

The Company’s standard payment terms generally require customers to pay 

30

 to 

60

 days after the Company satisfies the performance obligations. For those customers who are required to pay in advance, the Company satisfies the performance obligations typically within 

one

 quarter. The Company has elected 

not

 to determine whether contacts with customers contain significant financing components.

As of 

June 30, 2018, 

the Company’s unsatisfied performance obligations primarily included products held in consignment arrangements and customer purchase orders for products that the Company has 

not

 yet shipped. Because the Company expects to fulfill these performance obligations within 

one

 year, the Company has elected 

not

 to disclose the amount of these remaining performance obligations or the timing of recognition.

Changes to Financial Statement Line Items

The following tables compare the impact on the financial statement line items between the application of Topic 

606

 and Topic 

605

 as of 

June 30, 2018 

and for the 

three

 and

six

months ended 

June 30, 2018. 

The significant changes between the

two

standards are primarily attributable to the following:

● Under Topic  606,  the Company recognizes revenue for  three  U.S.-based distributors upon shipment of the products to them, net of an estimated amount for price adjustments. Under Topic  605,  the Company would have deferred the recognition of revenue and related costs for these U.S. distributors until the Company received notification from the distributors that the products had been sold to the end customers and the amount of price adjustments was fixed and finalized.

● Under Topic  606,  the Company records assets for product returns within other current assets, which primarily represent the carrying value of inventory it expects to recover from customers related to stock rotation returns. Under Topic  605,  such amounts would have been netted against the stock rotation reserve within current accrued liabilities.

● Under Topic  606,  the Company recorded a cumulative effect of initially applying the standard to retained earnings. Under Topic  605,  the Company would  not  have recorded this adjustment.
