for net sales by segment and countries.

Revenue Recognition

The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of loss and rewards of ownership do

not

transfer until the product has been received by the customer, the Company adjusts revenues and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and

may

include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily through direct sales and independent

third

-party distributors.

The Company has elected the practical expedient under ASC

340

to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than

one

year.

Revenue and Billing

The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price lists. The customer is invoiced when the Company’s products are shipped to them in accordance with the terms of the sales agreement. As the Company’s standard payment terms are less than

one

year, the Company has elected the practical expedient under ASC

606

not

assess whether a contract has a significant financing component. The Company also elected the practical expedient provided in ASC

606

18B

to treat all product shipping and handling activities as fulfillment activities, and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. This is similar to the Company’s prior practice and therefore the effect of the new guidance is immaterial.

Ship and Debit Program

Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or large volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company approves such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and the lower approved price. The Company establishes reserves for this program based on historic activity and actual authorizations for the debit and recognizes these debits as a reduction of revenue.

Return to Stock

The Company has a return to stock policy whereby certain customers, with prior authorization from Littelfuse management, can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns.

Volume Rebates

The Company offers volume based sales incentives to certain customers to encourage greater product sales. If customers achieve their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold.

Recently Adopted Accounting Standards

March 2017,

the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)

No.

2017

“Compensation-Retirement Benefits (Topic

715

): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost,” which changed the presentation of net periodic pension and post-retirement benefit cost (net benefit cost) within the Statement of Income. Under the previous guidance, net benefit cost was reported as an employee cost within operating income. The amendment required the bifurcation of net benefit cost, with the service cost component to be presented with other employee compensation costs in operating income while the other components will be reported separately outside of income from operations. ASU

No.

2017

was effective for the

first

quarter of

2018

with the Company adopting the new standard on

December 31, 2017.

January 2016,

the FASB issued ASU

No.

2016

01,

“Financial Instruments-Recognition and Measurement of Financial Assets and Financial Liabilities” which addressed certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The ASU requires the Company to recognize any changes in the fair value of certain equity investments in net income. Previously these changes were recognized in other comprehensive income ("OCI"). The Company adopted the new standard on

December 31, 2017,

on a modified retrospective basis, recognizing the cumulative effect as a

$9.8

million increase to retained earnings. As a result of the adoption of the new standard and change in fair value of our equity investments, for the

six

months ended

June 30, 2018,

the Company recognized an unrealized gain of

$2.8

million in Other (income) expense, net in the Condensed Consolidated Statements of Net Income.

May 2014,

the FASB issued ASU

No.

2014

09,

“Revenue from Contracts with Customers” (Topic

606

) which supersedes the revenue recognition requirements in ASC

605,

“Revenue Recognition.” This ASU provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The guidance permits

two

implementation approaches,

one

requiring retrospective application of the new standard with restatement of prior years and

one

requiring prospective application of the new standard with disclosure of results under old standards. The Company adopted the new standard on

December 31, 2017

using the modified retrospective method, however,

adjustment to retained earnings was needed. The new guidance did

not

have a material effect on the Company’s Condensed Consolidated Statements of Income. See the

Revenue Recognition

section above for further discussion.

October 2016,

the FASB issued ASU

No.

2016

16,

"Income Taxes” (Topic

740

). This ASU update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory. The tax consequences were previously deferred. The Company adopted the new standard on

December 31, 2017

and it did

not

have a material impact.

Recently Issued Accounting Standards

February 2016,

the FASB issued ASU

No.

2016

02,

"Leases" (Topic

842

). This ASU requires lessees to recognize, on the balance sheet, assets and liabilities for the rights and obligations created by leases of greater than

twelve

months. The accounting by lessors will remain largely unchanged. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after

December 15, 2018,

with early adoption permitted. Adoption will require a modified retrospective transition. The Company will adopt the standard in the

first

quarter of

2019.

The Company has made progress on assessing the Company’s portfolio of leases and compiling a central repository of all active leases. We are in the process of assessing the design of the future lease process and drafting a policy to address the new standard requirements. Key lease data elements are being evaluated including developing a methodology for determining the incremental borrowing rate across all countries where we have operations. While the Company has

not

yet completed its evaluation of the impact the new lease accounting standard will have on its Consolidated Financial Statements, the Company expects to recognize right of use assets and lease liabilities for its operating leases in the Consolidated Balance Sheet upon adoption.

January 2018,

the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the

2017

U.S. Tax Cuts and Jobs Act (the “Tax Act”). The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or treating any taxes on GILTI inclusions as period cost are both acceptable methods subject to an accounting policy election. The Company has

not

yet completed its assessment and therefore has

not

yet elected an accounting policy.

February 2018,

the FASB issued ASU

No.

2018

“Income Statement—Reporting Comprehensive Income (Topic

220

): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the Tax Act. The standard also requires entities to disclose whether or

not

they elected to reclassify the tax effects related to the Tax Act as well as their policy for releasing income tax effects from accumulated other comprehensive income. The standard allows the option of applying either a retrospective adoption, meaning the standard is applied to all periods in which the effect of the Tax Act is recognized, or applying the amendments in the period of adoption, meaning an adjustment is made to shareholder’s equity as of the beginning of the reporting period. ASU

2018

will be effective in the

first

quarter of

2019;

however early adoption is permitted for interim and annual periods, including the reporting period in which the Tax Act was enacted. The Company is currently evaluating the impact of ASU

2018

on the Consolidated Financial Statements.
