Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments which are of a normal recurring nature and considered necessary for a fair presentation of these financial statements have been included. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for other interim periods or for the year as a whole.

 

The balance sheet at December 31, 2017 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in Axcelis Technologies, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2017.

 

 

Note 2.  Stock-Based Compensation

 

The Company maintains the Axcelis Technologies, Inc. 2012 Equity Incentive Plan (the “2012 Equity Plan”), which became effective on May 2, 2012, and permits the issuance of options, restricted stock, restricted stock units and performance awards to selected employees, directors and consultants of the Company. The Company’s 2000 Stock Plan (the “2000 Stock Plan”) expired on May 1, 2012 and no new grants may be made under that plan after that date.  However, unexpired awards granted under the 2000 Stock Plan remain outstanding and subject to the terms of the 2000 Stock Plan. The Company also maintains the Axcelis Technologies, Inc. Employee Stock Purchase Plan (the “ESPP”), an Internal Revenue Code Section 423 plan.

 

The 2012 Equity Plan and the ESPP are more fully described in Note 11 to the consolidated financial statements in the Company’s 2017 Annual Report on Form 10-K.

 

The Company recognized stock-based compensation expense of $2.4 million and $1.7 million for the three month periods ended September 30, 2018 and 2017, respectively. The Company recognized stock-based compensation expense of $5.6 million and $4.3 million for the nine month periods ended September 30, 2018 and 2017, respectively. These amounts include compensation expense related to restricted stock units (“RSUs”), non-qualified stock options and stock to be issued to participants under the ESPP.

 

In the three month periods ended September 30, 2018 and 2017, the Company issued 0.1 million and 0.3 million shares of common stock, respectively, in relation to stock option exercises and vesting of RSUs. In the three month periods ended September 30, 2018 and 2017, the Company received proceeds of $0.5 million and $1.8 million, respectively, in connection with the exercise of stock options.

 

In the nine month periods ended September 30, 2018 and 2017, the Company issued 0.3 million and 1.9 million shares of common stock, respectively, in relation to stock option exercises, shares issued under the ESPP and vesting of RSUs. In the nine month periods ended September 30, 2018 and 2017, the Company received proceeds of $1.7 million and $11.4 million, respectively, in connection with the exercise of stock options and ESPP purchases.

 

Note 3.  Revenue

 

We design, manufacture and service ion implantation and other processing equipment used in the fabrication of semiconductor chips and sell our products to leading semiconductor chip manufacturers worldwide. We offer a complete line of high energy, high current and medium current implanters (“Systems”) for all application requirements. In addition, we provide extensive aftermarket lifecycle products and services (“Aftermarket”), including used tools, spare parts, equipment upgrades, maintenance service and customer training.

 

 

Under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers or (“ASC 606”), revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We measure revenue based on the consideration specified in the client arrangement, and revenue is recognized when the performance obligations in the client arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation based upon the relative standalone selling price for each performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. See Note 14 regarding the impact of the adoption of ASC 606 on our financial statements. To account for and measure revenue, the Company applies the following five steps:

 

 

A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) the Company determines that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration.

 

 

Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, the Company must apply judgment to determine whether promised goods and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation.

 

Our Systems sales consist of multiple performance obligations, including the system itself and obligations that are not delivered simultaneously with the system. These undelivered obligations might include a combination of installation services, extended warranty and support and spare parts, all of which are generally covered by a single sales price.

 

Our aftermarket business includes both products and services type arrangements. Performance obligations in these contracts consist of used tools, spare parts, equipment upgrades, maintenance services and customer training.

 

Customers who purchase new systems are provided an assurance-type warranty for one year after acceptance of the tool. For Aftermarket transactions, we provide customers an assurance-type warranty for 90 days. Customers can choose to purchase extended warranty terms with enhanced support similar to a service-type warranty ranging from one to three years. In accordance with ASC 606, assurance-type warranties are not considered a performance obligation, whereas service-type warranties are. 

 

 

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. In applying this guidance, Companies must also consider whether any significant financing components exist.

 

The transaction price for all transactions is based on the price reflected in the individual customer’s purchase order. Variable consideration has not been identified as a significant component of the transaction price for any of our transactions.

 

For those transactions where all performance obligations will be satisfied within one year or less, the Company is applying the practical expedient outlined in ASC 606-10-32-18. This practical expedient allows the Company not to adjust promised consideration for the effects of a significant financing component if the Company expects at contract inception the period between when the Company transfers the promised good or service to a customer and when the customer pays for that good or service will be one year or less. For those transactions that are expected to be completed after one year, the Company has assessed that there are no significant financing components because any difference between the promised consideration and the cash selling price of the good or service is for reasons other than the provision of financing.

 

 

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation.

 

Where required, the Company determines standalone selling price (SSP) for each obligation based on consideration of both market and Company specific factors, including the selling price and profit margin for similar products, the cost to produce, and the anticipated margin.

 

For those contracts that contain multiple performance obligations (primarily systems sales, as well as some aftermarket contracts requiring both time and material inputs), the company must determine SSP. The Company used a cost plus margin approach in determining the SSP for any materials related performance obligations (such as upgrades, spare parts, systems). To determine the SSP for labor related performance obligations (such as the labor component of installation), the Company used directly observable inputs based on the standalone sale prices for these services.

 

 

The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized over time if either 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity

and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. Examples of control are using the asset to produce goods or services, enhance the value of other assets, settle liabilities, and holding or selling the asset.  For over time recognition, ASC 606 requires the Company to select a single revenue recognition method for the performance obligation that faithfully depicts the Company’s performance in transferring control of the goods and services. The guidance allows entities to choose between two methods to measure progress toward complete satisfaction of a performance obligation:

 

Output methods - recognize revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract (e.g. surveys of performance completed to date, appraisals of results achieved, milestones reached, time elapsed, and units produced or units delivered); and

 

Input methods - recognize revenue on the basis of the entity’s efforts or inputs to the satisfaction of a performance obligation (e.g., resources consumed, labor hours expended, costs incurred, or time elapsed) relative to the total expected inputs to the satisfaction of that performance obligation.

 

The Company has the right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date (i.e. certain aftermarket contracts), as such the Company has elected a practical expedient to recognize revenue in the amount to which the entity has a right to invoice for such services.

 

Product related revenues (whether for systems or aftermarket business) are recognized at a point in time, when they are shipped or delivered, depending on shipping terms. 

 

For installation services, revenue is recognized at a point in time, once the installation of the tool is complete. The nature of the installation services are such that the customer does not simultaneously receive and consume the benefits provided by the entity’s performance, nor does performance of installation services create or enhance an asset that the customer controls. Installation services do not create an asset with an alternative use to the entity, and the entity does not have an enforceable right to payment for performance completed to date. 

 

Service-type warranties for any product are recognized over time, as these represent a stand ready obligation to service the product during the warranty period. Progress in the satisfaction of these performance obligations will be measured using an input method of time elapsed.

 

Maintenance and service contracts are recognized over time.  Progress in the satisfaction of these performance obligations will be measured using an input method of either time elapsed in the case of fixed period contracts, or labor hours expended, in the case of project based contracts.

 

 

The Company recognizes an asset related to incremental costs of obtaining a contract with a customer if the Company expects to recover those costs. The Company will recognize an asset from costs incurred to fulfill a contract only if such costs relate directly to a contract that the entity can specifically identify, the costs generate or enhance resources of the Company that will be used in satisfying performance obligations in the future, and the costs are expected to be recovered. Any assets recognized related to costs to obtain or fulfill a contract are amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates.

 

In substantially all of our business transactions, we incur incremental costs to obtain contracts with customers, in the form of sales commissions. We maintain a commission program which awards our employees for System sales, aftermarket activity and other individual goals. Under ASC 606, an asset shall be amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. However, ASC 606 provides a practical expedient to allow for the recognition of commission expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

Based on the nature of the Company’s commission agreements, all commissions are expensed as incurred based upon the expectation that the amortization period would be one year or less. 

 

 

To reflect the organization of the Company’s business operations, management also divides revenue into two categories: revenue from sales of new Systems and revenue arising from the sale of used systems, parts and labor to customers who own systems, which we refer to as Aftermarket.

 

Below are the revenues by categories used by management for the periods covered in this report:

 

 

*The impact upon adoption of ASC 606 was a decrease to Systems revenue of $0.6 million for the three month period ended September 30, 2018 and $1.3 million increase for the and nine month period ended September 30, 2018. Please refer to Note 14 for additional discussion of ASC 606 adoption impact on revenue amounts and comparable revenue figures.

 

The increase in revenue in the nine month period ended September 30, 2018, in comparison to the nine month period ended September 30, 2017, is attributable to an increase in sales of our Purion products and Aftermarket business.

 

 

Global economic conditions have a direct impact on our revenue. We are substantially dependent on sales of our products and services to customers outside the United States. Adverse economic conditions, political instability, potential adverse tax consequences and volatility in exchange rates pose a risk that our clients may reduce, postpone or cancel spending for our products and services, which would impact our revenue.

 

Revenue by geographic markets is determined based upon the location to which our products are shipped and where our services are performed. Revenue in our principal geographic markets is as follows:

 

 

*The impact upon adoption of ASC 606 for the three months ended September 30, 2018 was a decrease in revenue to Asia of $0.8 million and an increase to Europe of $0.2 million. The impact upon adoption of ASC 606 for the nine months ended September 30, 2018 was primarily an increase in revenue to Asia of $1.5 million, partially offset by a decline to North America of $0.2 million. Please refer to Note 14 for additional discussion of ASC 606 adoption impact on revenue amounts and comparable revenue figures.

 

 

Contract assets and contract liabilities are as follows:

 

 

 

Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate to payments invoiced or received in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations. The decrease in contract liabilities of $0.4 million from December 31, 2017 to September 30, 2018 is primarily due to the reclassification of $1.6 million relating to our adoption of ASC 606, offset by the timing of system acceptances.  

 

The majority of our system transactions have payment terms that are 90% due upon shipment of the tool and 10% due upon installation. Aftermarket transaction payment terms are such that payment is due either within 30 or 60 days of service provided or delivery of parts.

 

As of September 30, 2018, the Company had deferred revenue of $17.8 million. This represents the portion of the transaction price for contracts with customers allocated to the performance obligations that remain unsatisfied or partially unsatisfied.  Short-term deferred revenue of $14.4 million represents performance obligations that will be satisfied within the next 12 months. This amount relates primarily to installation and non-standard warranty performance obligations for system sales. Long-term deferred revenue of $3.4 million relates primarily to unsatisfied extended warranty performance obligations that we expect to be satisfied within the next 24 months.

 

Note 4.  Computation of Net Earnings per Share

 

Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted‑average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased by the number of additional common shares that would have been outstanding if the potentially dilutive common shares issuable for stock options and restricted stock units had been issued, calculated using the treasury stock method.

 

The components of net earnings per share are as follows:

 

 

Diluted weighted average common shares outstanding does not include options and restricted stock units outstanding to purchase 0.3 million and four thousand common equivalent shares for the three month periods ended September 30, 2018 and 2017, respectively, and does not include options and restricted stock units outstanding to purchase eleven thousand and 0.2 million common equivalent shares for the nine month periods ended September 30, 2018 and 2017, respectively, as their effect would have been anti-dilutive.

 

 

Note 5.  Accumulated Other Comprehensive Income

 

The following table presents the changes in accumulated other comprehensive income, net of tax, by component, for the nine months ended September 30, 2018:

 

 

 

 

Note 6. Cash, cash equivalents and restricted cash

 

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the statement of financial position that sum to the total of the amounts shown in the statement of cash flows.

 

 

The restricted cash balance of $6.9 million as of September 30, 2018 is the result of (i) a $5.9 million letter of credit associated with a security deposit for the lease of our corporate headquarters in Beverly, Massachusetts, (ii) a $0.8 million letter of credit relating to workers’ compensation insurance, (iii) a bank guarantee of our performance relating to customer payment in the amount of $0.1 million and (iv) a $0.1 million deposit relating to customs activity. The restricted cash balance of $7.5 million as of December 31, 2017 includes (i) a $5.9 million letter of credit associated with a security deposit for the lease of our corporate headquarters in Beverly, Massachusetts, (ii) a

$0.8 million letter of credit relating to workers’ compensation insurance, a $0.7 million letter of credit associated with a bank guarantee and a $0.1 million deposit relating to customs activity. 

 

Note 7.  Inventories, net

 

The components of inventories are as follows:

 

 

When recorded, inventory reserves reduce the carrying value of inventories to their net realizable value. The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market conditions. The Company regularly evaluates the ability to realize the value of inventories based on a combination of factors including the following: forecasted sales or usage, estimated product end of life dates, estimated current and future market value and new product introductions. Purchasing and usage alternatives are also explored to mitigate inventory exposure.

 

Note 8.  Product Warranty

 

The Company generally offers a one year warranty for all of its systems, the terms and conditions of which vary depending upon the product sold. For all systems sold, the Company accrues a liability for the estimated cost of standard warranty at the time of system shipment and defers the portion of systems revenue attributable to the fair value of non-standard warranty. Costs for non-standard warranty are expensed as incurred. Factors that affect the Company’s warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts the amount as necessary.

 

The changes in the Company’s standard product warranty liability are as follows:

 

 

 

Note 9.  Fair Value Measurements

 

Certain assets on the Company’s balance sheets are reported at their fair value. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or

most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

 

(a)  Fair Value Hierarchy

 

The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

 

Level 1 - applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

 

Level 2 - applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

 

Level 3 - applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

 

(b)  Fair Value Measurements

 

The Company’s money market funds and short-term investments are included in cash and cash equivalents in the consolidated balance sheets and are considered a level 1 investment as they are valued at quoted market prices in active markets.

 

The following table sets forth the Company’s assets by level within the fair value hierarchy:

 

 

 

(c)  Other Financial Instruments

 

The carrying amounts reflected in the consolidated balance sheets for accounts receivable, prepaid expenses and other current assets and non-current assets, restricted cash, accounts payable and accrued expenses approximate fair value due to their short-term maturities.

 

Note 10.  Financing Arrangements

 

On January 30, 2015, the Company sold its corporate headquarters facility in Beverly Massachusetts for $48.9 million. As part of the sale, the Company also entered into a 22-year lease agreement of our headquarters facility. This sale leaseback is accounted for as a financing arrangement under generally accepted accounting principles and, as such, the Company has recorded a financing obligation of $47.7 million as of September 30, 2018. The associated lease payments are deemed to include both an interest component and payment of principal, with the underlying liability being extinguished at the end of the original lease term. The Company posted a security deposit of $5.9 million in the form of an irrevocable letter of credit at the time of the closing. This letter of credit is cash collateralized and the associated cash is included in long-term restricted cash.

 

Note 11.  Income Taxes

 

On December 22, 2017, the Tax Cuts and Jobs Act ("TCJA") was enacted into law, which significantly changed existing U.S. tax law and includes numerous provisions that affect our business, such as reducing the U.S. federal statutory tax rate and adopting a territorial tax system. The TCJA reduces the U.S. federal statutory tax rate from 35% to 21%, effective January 1, 2018. The TCJA also includes a provision to tax global intangible low-taxed income ("GILTI") of foreign subsidiaries and a base erosion anti-abuse tax ("BEAT") measure that taxes certain payments between a U.S. corporation and its subsidiaries. The Company considered the available guidance and has incorporated the relevant provisions of GILTI into the income tax provision and concluded that the provisions of BEAT do not apply to the Company at this time.

 

In accordance with Staff Accounting Bulletin 118, the Company disclosed in its 2017 Annual Report on Form 10-K that it is able to determine a reasonable estimate for certain effects of tax reform and has recorded that estimate as a provisional amount. The Company intends to use the one-year measurement period to update the provisional amount recorded as it finalizes its analysis relating to certain matters, such as developing interpretations of provisions to the TCJA, changes to certain estimates and amounts related to the Earning and Profits of certain subsidiaries and the filing of tax returns. Also, Treasury regulations, administrative interpretations, or court decisions interpreting the TCJA may require further adjustments and changes to the provisional amounts.

 

During the three months ended September 30, 2018 we recorded an income tax provision of $0.5 million. During the nine months ended September 30, 2018 we recorded an income tax provision of $7.0 million. Included in the income tax provision for the three and nine months ended September 30, 2018 is a tax benefit of $1.4 million relating to the calculation of transition tax under the TCJA. This tax benefit reduced by 15.2% and 3.1% the otherwise effective tax rate for the three and nine months ended September 30, 2018, respectively. Also included in the income tax provision for the nine months ended September 30, 2018 is a tax benefit of $0.3 million recognized upon the expiration of the statute of limitations regarding an uncertain tax position previously recorded. The related interest and penalties previously accrued were reversed resulting in a reduction to interest expense of $0.2 million.

 

The change in the income tax provision for the three and nine months periods ended September 30, 2018 compared to the prior year was primarily due to the release of a significant portion of our valuation allowance in the fourth quarter of 2017. Prior to the release of the valuation allowance, the Company reported in its consolidated statements of operations only the amount of taxes actually payable. Subsequent to the release of the valuation allowance, tax expense also reflects the tax liability that would be payable without consideration of the usage of any net operating loss carryforwards. We have significant net operating loss carryforwards in the United States and certain European jurisdictions, and, as a result, we do not currently pay significant income taxes in those jurisdictions. At December 31, 2017, the Company had $90.3 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income tax liabilities in future years.

 

 

 

Note 12.  Concentration of Risk

 

For the three months ended September 30, 2018, three customers accounted for 17.8%, 13.6% and 13.1% of total revenue, respectively. For the three months ended September 30, 2017,  two customers accounted for 25.9% and 15.9% of total revenue, respectively.

 

For the nine months ended September 30, 2018,  two customers accounted for 22.9% and 10.8% of total revenue, respectively. For the nine months ended September 30, 2017, four customers accounted for 23.6%, 18.0%, 13.4% and 10.5% of total revenue, respectively.

 

At September 30, 2018, three customers accounted for 16.0%, 13.8% and 12.5% of accounts receivable, respectively. At December 31, 2017, three customers accounted for 19.8%, 11.8% and 10.6% of accounts receivable, respectively.

 

Note 13.  Contingencies

 

(a)  Litigation

 

The Company is, from time to time, a party to litigation that arises in the normal course of its business operations. The Company is not presently a party to any litigation that it believes might have a material adverse effect on its business operations.

 

(b)  Indemnifications

 

The Company’s system sales agreements typically include provisions under which the Company agrees to take certain actions, provide certain remedies and defend its customers against third-party claims of intellectual property infringement under specified conditions and to indemnify customers against any damage and costs awarded in connection with such claims. The Company has not incurred any material costs as a result of such indemnifications and has not accrued any liabilities related to such obligations in the accompanying consolidated financial statements.

 

Note 14.  Recent Accounting Guidance

 

 

Effective January 1, 2018, we adopted FASB ASC Topic 606, Revenue from Contracts with Customers, or ASC 606. In accordance with ASC 606, we changed certain characteristics of our revenue recognition accounting policy as described below. In our adoption, ASC 606 was applied only to open contracts using the modified retrospective method, where the cumulative effect of the initial application is recognized as an adjustment to opening retained earnings at January 1, 2018. Therefore, comparative prior periods have not been adjusted and continue to be reported under FASB ASC Topic 605, Revenue Recognition, or ASC 605.

Upon adoption of ASC 606, we changed our accounting policy for the installation performance obligation included in all system sales. Previously under ASC 605, the Company deferred revenue for the greater of the fair value of the installation or the portion of contract consideration for which collection was contingent upon installation completion (the “retention”). The concept of contingent consideration is no longer relevant under ASC 606 and therefore we will only defer the portion of the transaction price allocated to the installation performance obligation. As a result of this change, we recorded a cumulative effect adjustment to increase retained earnings and decrease deferred revenue on January 1, 2018 by $1.6 million. Upon the adoption, all new contracts will be accounted for under ASC 606. Disclosures related to the nature, amount and timing of revenue and cash flows arising from contracts with customers are included in Note 3.

The guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15,
