NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Overview. Agilent Technologies, Inc. ("we", "Agilent" or the "company"), incorporated in Delaware in May 1999, is a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow.

Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters.

Basis of Presentation . We have prepared the accompanying financial data for the three and six months ended April 30, 2018 and 2017 pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles ("GAAP") in the U.S. have been condensed or omitted pursuant to such rules and regulations. The October 31, 2017 condensed balance sheet data was derived from audited financial statements but does not include all the disclosures required in audited financial statements by U.S. GAAP. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended October 31, 2017 .

In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary for a fair statement of our condensed consolidated balance sheet as of April 30, 2018 and October 31, 2017 , condensed consolidated statement of comprehensive income (loss) for the three and six months ended April 30, 2018 and 2017 , condensed consolidated statement of operations for the three and six months ended April 30, 2018 and 2017 , and condensed consolidated statement of cash flows for the six months ended April 30, 2018 and 2017 .

Revision of Services and Other, Product Net Revenue and related Cost of Sales. In 2018, we identified a stream of service revenues that had been presented as product revenue in the prior year.  We have now revised prior year's presentation to show the revenue within services and other to conform with the current presentation in fiscal 2018.   The cost of sales associated with these newly identified service revenues has also been revised to align with the new presentation. For the three and six months ended April 30, 2017 service and other revenue increased $3 million and $6 million , respectively, and service and other cost of sales increased $2 million and $4 million , respectively, with corresponding reductions in product revenue and cost of sales. These corrections to the classifications are not considered to be material to current or prior periods and had no impact to our results of operations previously reported in our condensed consolidated statement of operations.

Use of Estimates. The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, share-based compensation, retirement and post-retirement benefit plan assumptions, goodwill and purchased intangible assets and accounting for income taxes.

Variable Interest Entities. We make a determination upon entering into an arrangement whether an entity in which we have made an investment is considered a Variable Interest Entity ("VIE").  The company evaluates its investments in privately held companies on an ongoing basis. We have determined that as of April 30, 2018 there were no VIE's required to be consolidated in the company's consolidated financial statements because we do not have a controlling financial interest in any of the VIE's that we have invested in nor are we the primary beneficiary. We account for these investments under either the equity or cost method, depending on the circumstances. We periodically reassess whether we are the primary beneficiary of a VIE. The reassessment process considers whether we have acquired the power to direct the most significant activities of the VIE through changes in governing documents or other circumstances. We also reconsider whether entities previously determined not to be VIEs have become VIEs, based on changes in facts and circumstances including changes in contractual arrangements and capital structure. As of April 30, 2018 , the carrying value of our cost method investment in Lasergen, Inc. ("Lasergen"), a VIE, was $80 million with a maximum exposure of $80 million . The investments are included on the long-term investments line of the condensed consolidated balance sheet. Agilent's initial ownership stake in Lasergen was 48 percent . During the three months ended April 30, 2018 , we exercised our option and signed the merger agreement to acquire all of the remaining shares of Lasergen, Inc. that we

did not already own for an additional cash consideration of $105 million . The acquisition of Lasergen was completed on May 7, 2018. 

Acquisition. On March 7, 2018 we signed an agreement to acquire Advanced Analytical Technologies, Inc ("AATI") in a merger transaction for $250 million in cash, subject to certain purchase price adjustments. AATI, headquartered in Ankeny, Iowa, develops, manufactures and markets capillary electrophoresis based solutions for automated nucleic acid analysis. The financial results of AATI will be included within Agilent's from the date of the close. On May 31, 2018, we completed the acquisition of Advanced Analytical Technologies, Inc ("AATI").

Fair Value of Financial Instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. The fair value of our senior notes, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy is lower than the carrying value by approximately $4 million as of April 30, 2018 and exceeds the carrying value by approximately $58 million as of October 31, 2017 . The change in the fair value over carrying value in the six months ended April 30, 2018 is primarily due to fluctuations in market interest rates. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 8, "Fair Value Measurements" for additional information on the fair value of financial instruments.

 2. NEW ACCOUNTING PRONOUNCEMENTS

There were no changes to the new accounting pronouncements not yet adopted as described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2017 except for the following:

In May 2014, the Financial Accounting Standards Board ("FASB") issued new revenue recognition guidance, Accounting Standard Codification Topic 606, Revenue from contract with customers, which 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 objective of the new revenue standard is to significantly enhance comparability and clarify principles of revenue recognition practices across entities, industries, jurisdictions and capital markets. The guidance is effective for us at the beginning in November 1, 2018. We expect to adopt this standard on November 1, 2018 through application of the modified retrospective method reflecting the cumulative effect of initially applying the new guidance to revenue recognition in the first quarter of fiscal 2019. Under the new guidance, there are specific criteria to determine if a performance obligation should be recognized over time or at a point in time. We expect that in some cases the revenue recognition timing under the new guidance will change from current practice.  We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and disclosures.

In February 2018, the FASB issued amendments to reporting comprehensive income to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act that was enacted in December 2017 that reduced the U.S. federal corporate income tax rate and made other changes to U.S. federal tax laws. The amendments in this update also require certain disclosures about stranded tax effects. The amendments are effective for us beginning November 1, 2019, and for interim periods within that fiscal year and should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. We expect to adopt this guidance on November 1, 2018. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements and disclosures.

In February 2018, FASB issued technical corrections and improvements to amendments published in January 2016 to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The provisions under these corrections and improvements are effective for us beginning November 1, 2018, and for interim periods within that year. Early adoption is not permitted. We currently do not expect this guidance to have a material impact on our consolidated financial statements and disclosures.

In March 2018, FASB issued amendments to SEC Staff Accounting Bulletin ("SAB") No. 118. These amendments modified certain SEC material in Topic 740 for the income tax accounting implications of the recently issued Tax Act and generally serves to codify the SEC's guidance released in SAB No. 118. These amendments are effective for us beginning November 1, 2018, and interim periods with that year. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements and disclosures.

Other amendments to GAAP in the U.S. that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our consolidated financial statements upon adoption.

3.     SHARE-BASED COMPENSATION

Agilent accounts for share-based awards in accordance with the provisions of the authoritative accounting guidance which requires the measurement and recognition of compensation expense for all share-based payment awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under our employee stock purchase plan ("ESPP") and performance share awards granted to selected members of our senior management under the long-term performance plan ("LTPP") based on estimated fair values.

Participants in the LTPP are entitled to receive unrestricted shares of the company's stock after the end of a three-year period, if specified performance targets are met. Certain LTPP awards are generally designed to meet the criteria of a performance award with the performance metrics and peer group comparison based on the Total Stockholders' Return ("TSR") set at the beginning of the performance period. Effective November 1, 2015, the Compensation Committee of the Board of Directors approved another type of performance stock award, for the company's executive officers and other key employees. Participants in this program are also entitled to receive unrestricted shares of the company's stock after the end of a three-year period, if specified performance targets over the three-year period are met. The performance target for grants made in 2016 were based on Operating Margin ("OM") and the performance grants made in 2017 and 2018 were based on Earnings Per Share ("EPS"). The performance targets for the LTPP-EPS grants for year 2 and year 3 of the performance period will be set in the first quarter of year 2 and year 3, respectively. All LTPP awards granted after November 1, 2015, are subject to a one-year post-vest holding period.

The final LTPP award may vary from zero to 200 percent of the target award. The maximum award value for awards granted in 2016 and 2017 cannot exceed 300 percent of the grant date target value. We consider the dilutive impact of these programs in our diluted net income per share calculation only to the extent that the performance conditions are expected to be met. Restricted stock units generally vest, with some exceptions, at a rate of 25 percent per year over a period of four years from the date of grant.

The impact on our results for share-based compensation was as follows:

At April 30, 2018 and October 31, 2017 , there was no share-based compensation capitalized within inventory.

The following assumptions were used to estimate the fair value of awards granted.

Shares granted under the LTPP (TSR) were valued using a Monte Carlo simulations model. The Monte Carlo simulation fair value model requires the use of highly subjective and complex assumptions, including the price volatility of the underlying stock.  For the volatility of our 2017 and 2018 LTPP (TSR) grants, we used our own historical stock price volatility.  

The ESPP allows eligible employees to purchase shares of our common stock at 85 percent of the price at purchase and uses the purchase date to establish the fair market value.

The estimated fair value of restricted stock units, LTPP (OM) and LTPP (EPS) awards is determined based on the market price of Agilent's common stock on the date of grant adjusted for expected dividend yield. The compensation cost for LTPP (OM) and LTPP (EPS) reflects the cost of awards that are probable to vest at the end of the performance period.

All awards granted in 2016 and thereafter to our senior management employees have a one-year post-vest holding restriction. The estimated discount associated with post-vest holding restrictions is calculated using the Finnerty model (see table above). The model calculates the potential lost value if the employee were able to sell the shares during the lack of marketability period, instead of being required to hold the shares. The model used the same historical stock price volatility and dividend yield assumption used for the Monte Carlo simulations model and an expected dividend yield to compute the discount.

4.     INCOME TAXES

For the three and six months ended April 30, 2018 , the company's income tax expense was $22 million with an effective tax rate of 9.7 percent and $575 million with an effective tax rate of 125.0 percent , respectively. For the six months ended April 30, 2018, our effective tax rate and the resulting provision for income taxes were significantly impacted by the discrete charge of $533 million related to the enactment of the U.S. Tax Cuts and Jobs Act (the "Tax Act") as discussed below. The income tax provision for the three and six months ended April 30, 2018 also includes the excess tax benefits from stock based compensation of $7 million and $18 million , respectively.

For the three and six months ended April 30, 2017 , the company's income tax expense was $27 million with an effective tax rate of 14.1 percent and $52 million with an effective tax rate of 13.5 percent , respectively. The income tax provision for the three and six months ended April 30, 2017 included net discrete tax benefits of $1 million and $3 million , respectively.  The significant component of the net discrete tax benefit for the three months ended April 30, 2017 included  $5 million  of tax benefit related to return-to-provision adjustments in foreign jurisdictions. The significant component of the net discrete tax benefit for the six months ended April 30, 2017 included a $11 million tax expense related to an employee pension settlement gain and $7 million of tax benefit for the settlement of an audit in Italy, and $5 million tax benefit related to return-to-provision adjustments in foreign jurisdictions.

2017 U.S. Tax Reform - Tax Cuts and Jobs Act

On December 22, 2017, the Tax Cuts and Jobs Act ("Tax Act") was enacted into law. The Tax Act enacted significant changes affecting our fiscal year 2018, including, but not limited to, (1) reducing the U.S. federal corporate tax rate and (2) imposing a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that had not been previously taxed in the U.S.

The Tax Act also establishes new tax provisions affecting our fiscal year 2019, including, but not limited to, (1) creating a new provision designed to tax global intangible low-tax income ("GILTI"); (2) generally eliminating U.S. federal taxes on dividends from foreign subsidiaries; (3) eliminating the corporate alternative minimum tax ("AMT"); (4) creating the base erosion anti-abuse tax ("BEAT"); (5) establishing a deduction for foreign derived intangible income ("FDII"); (6) repealing domestic production activity deduction; and (7) establishing new limitations on deductible interest expense and certain executive compensation.

The Tax Act reduces the U.S. federal corporate tax rate from 35 percent to 21 percent effective January 1, 2018. Due to our fiscal year end, the lower corporate tax rate will be phased in, resulting in a U.S. statutory federal rate of 23 percent for our fiscal year ending October 31, 2018 and 21 percent for subsequent fiscal years.

ASC 740, Income Taxes, requires companies to recognize the effect of the tax law changes in the period of enactment. However, the SEC staff issued Staff Accounting Bulletin 118 ("SAB 118") which allows companies to record provisional amounts during a measurement period not extending beyond one year from the Tax Act enactment date. During the three months ended January 31, 2018, the company recognized a provisional amount of $533 million which includes (1) an estimated provision of $480 million of U.S. transition tax and correlative items on deemed repatriated earnings of non-U.S. subsidiaries and (2) an estimated provision of $53 million associated with the impact of decreased U.S. corporate tax rate as described below. As of April 30, 2018 , the company has not completed the accounting for all the impacts of the Tax Act. We were able to reasonably estimate certain effects and, therefore, recorded provisional adjustments associated with the Tax Act in the three months ended January 31, 2018, and they remain unchanged as of April 30, 2018.

Deemed Repatriation Transition Tax ("Transition Tax") : The Transition Tax is based on the company's total unrepatriated post-1986 earnings and profits ("E&P") of its foreign subsidiaries and the amount of non-U.S. taxes paid (Tax Pools) on such earnings. Historically, the company permanently reinvested a significant portion of these post-1986 E&P outside the U.S. For the remaining portion, the company previously accrued deferred taxes. Since the Tax Act required all foreign earnings to be taxed currently, the company recorded a provisional income tax expense of $643 million for its one-time transition U.S. federal tax and a benefit of $163 million for the reversal of related deferred tax liabilities. The resulting $480 million net transition tax, reduced by existing tax credits, will be paid over 8 years in accordance with the election available under the Tax Act. These amounts represent the best estimate of all required calculations based on currently available information and do not include any potential state tax impacts. The one-time Transition Tax is based in part on cash and illiquid asset amounts present on various comparable measurement dates, some of which are as of our future fiscal year end. As a result, the company's calculation of the Transition Tax will change as the measurement dates occur and as federal and state tax authorities provide further guidance.

Reduction of U.S. Federal Corporate Tax Rate : The reduction of the corporate income tax rate requires companies to remeasure their deferred tax assets and liabilities as of the date of enactment. The provisional amount recorded in the six months ended April 30, 2018 for the remeasurement due to tax rate change is $53 million . We have not yet completed our accounting for the measurement of deferred taxes. To calculate the remeasurement of deferred taxes, we estimated when the existing deferred taxes will be settled or realized. These estimates may be affected by activities in the remaining quarters and other analysis related to the Tax Act, including, but not limited to, the impact of state conformity to the tax law change.

GILTI: The Tax Act subjects a U.S. corporation to tax on its GILTI. The U.S. GAAP allows companies to make an accounting policy election to either (1) treat taxes due on future GILTI inclusions in the U.S. taxable income as a current-period expense when incurred ("period cost method") or (2) factoring such amounts into a company's measurement of its deferred taxes ("deferred method"). Our analysis of the new GILTI rules and how they may impact us is incomplete. Accordingly, we have not made a policy election regarding the treatment of GILTI tax.

Indefinite Reinvestment Assertion: The company incurred U.S. tax on substantially all of the prior accumulated earnings of its foreign subsidiaries as part of the Transition Tax. This increased the company's previously taxed earnings and will allow for the repatriation of the majority of its foreign earnings without any U.S. federal tax. However, any repatriation of its foreign earnings could still be subjected to withholding taxes, state taxes or other income taxes that might be incurred. The company's analysis is incomplete at this time with respect to its investments intentions for its accumulated foreign earnings. During the period prescribed by SAB 118, the company will evaluate, among other factors, the need for cash within and outside the United States, legal entity capitalization requirements, cash controls imposed in foreign jurisdictions, withholding taxes and the availability to offset with foreign tax credits in determining its investment assertion on its accumulated foreign earnings.

Our estimates as described above, may change as a result of future guidance and interpretation from the Internal Revenue Service, the SEC, the FASB and various other taxing jurisdictions. In particular, we anticipate the U.S. state jurisdictions will continue to determine and announce their conformity or decoupling from the Tax Act either in its entirety or with respect to specific provisions. All of these potential legislative and interpretive actions could result in adjustments to our provisional estimates when the accounting for the income tax effects of the Tax Act is completed.

There were no substantial changes from our 2017 Annual Report on Form 10-K to the status of the open tax years in the first six months of fiscal year 2018. In the U.S., tax years remain open back to the year 2014 for federal income tax purposes and the year 2000 for significant states. In other major jurisdictions where the company conducts business, the tax years generally remain open back to the year 2001.

With these jurisdictions and the U.S., it is reasonably possible there could be significant changes to our unrecognized tax benefits in the next twelve months due to either the expiration of a statute of limitation or a tax audit settlement. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, management is unable to estimate the range of possible changes to the balance of our unrecognized tax benefits.

5. NET INCOME PER SHARE

The following is a reconciliation of the numerator and denominator of the basic and diluted net income per share computations for the periods presented below:

The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense collectively are assumed proceeds to be used to repurchase hypothetical shares. An increase in the fair market value of the company's common stock can result in a greater dilutive effect from potentially dilutive awards.

We exclude stock options with exercise prices greater than the average market price of our common stock from the calculation of diluted earnings per share because their effect would be anti-dilutive. In addition, we exclude from the calculation of diluted earnings per share stock options, ESPP, LTPP and restricted stock awards whose combined exercise price and unamortized fair value were greater than the average market price of our common stock because their effect would also be anti-dilutive.  

For the three months ended April 30, 2018 , 96,800 potential common shares were excluded from the calculation of diluted earnings per share. For the six months ended April 30, 2018 , the diluted net loss per share is the same as basic net loss per share as the effects of all 6.6 million potential common shares outstanding would be anti-dilutive. For the three and six months ended April 30, 2017 , 1,000 and 500 potential common shares were excluded from the calculation of diluted earnings per share.

6. INVENTORY

7. GOODWILL AND OTHER INTANGIBLE ASSETS

The following table presents goodwill balances and the movements for each of our reportable segments during the six months ended April 30, 2018 :

The components of other intangible assets as of April 30, 2018 and October 31, 2017 are shown in the table below:

During the six months ended April 30, 2018 , we recorded additions to goodwill of $5 million and additions to other intangible assets of $2 million related to an acquisition. We also acquired approximately $1 million of third party technologies and licenses during the six months ended April 30, 2018. During the six months ended April 30, 2018 , other intangible assets, net increased $2 million due to the impact of foreign exchange translation.

Each quarter we review the events and circumstances to determine if impairment of indefinite-lived intangible assets and goodwill is indicated. There were no indicators of impairments of indefinite-lived intangible assets or goodwill during the three and six months ended April 30, 2018 and 2017 , respectively.

Amortization expense of intangible assets was $26 million and $52 million for the three and six months ended April 30, 2018 , respectively. Amortization expense of intangible assets was $32 million and $64 million for the three and six months ended April 30, 2017 , respectively.

Future amortization expense related to existing finite-lived purchased intangible assets for the remainder of fiscal year 2018 and for each of the five succeeding fiscal years and thereafter is estimated below:

8. FAIR VALUE MEASUREMENTS

The authoritative guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability.

Fair Value Hierarchy

The guidance establishes a fair value hierarchy that prioritizes the use of inputs used in valuation techniques into three levels. 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. There are three levels of inputs that may be used to measure fair value:

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 included within level 1 that are observable, either directly or indirectly, for the asset or liability such as: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in less active markets; or other inputs that 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.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Financial assets and liabilities measured at fair value on a recurring basis as of April 30, 2018 were as follows:

Financial assets and liabilities measured at fair value on a recurring basis as of October 31, 2017 were as follows:

Our money market funds and trading securities investments are generally valued using quoted market prices and therefore are classified within level 1 of the fair value hierarchy. Our derivative financial instruments are classified within level 2, as there is not an active market for each hedge contract, but the inputs used to calculate the value of the instruments are tied to active markets. Our deferred compensation liability is classified as level 2 because, although the values are not directly based on quoted market prices, the inputs used in the calculations are observable.

Trading securities, which is comprised of mutual funds, bonds and other similar instruments, and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in net income.

Certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive loss within stockholders' equity. Realized gains and losses from the sale of these instruments are recorded in net income.

Impairment of Investments. There were no impairments of investments for the three and six months ended April 30, 2018 and 2017 .

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

For the three and six months ended April 30, 2018 and 2017 , there were no impairments of long-lived assets held and used or long-lived assets held for sale.

9. DERIVATIVES

We are exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal course of our business. As part of our risk management strategy, we use derivative instruments, primarily forward contracts, purchased options to hedge economic and/or accounting exposures resulting from changes in foreign currency exchange rates.

Fair Value Hedges

We are exposed to interest rate risk due to the mismatch between the interest expense we pay on our loans at fixed rates and the variable rates of interest we receive from cash, cash equivalents and other short-term investments. We have issued long-term debt in U.S. dollars at fixed interest rates based on the market conditions at the time of financing. The fair value of our fixed rate debt changes when the underlying market rates of interest change, and, in the past, we have used interest rate swaps to change our fixed interest rate payments to U.S. dollar LIBOR-based variable interest expense to match the floating interest income from our cash, cash equivalents and other short term investments. As of April 30, 2018 , all interest rate swap contracts had either been terminated or had expired.

On August 9, 2011, we terminated five interest rate swap contracts related to our 2020 senior notes that represented the notional amount of $500 million . The remaining gain to be amortized at April 30, 2018 was $9 million . All deferred gains from terminated interest rate swaps are being amortized over the remaining life of the respective senior notes.

Cash Flow Hedges

We enter into foreign exchange contracts to hedge our forecasted operational cash flow exposures resulting from changes in foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities between one and twelve months. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance and are assessed for effectiveness against the underlying exposure every reporting period. Changes in the time value of the foreign exchange contract are excluded from the assessment of hedge effectiveness and are recognized in other income (expense) each period. The changes in fair value of the effective portion of the derivative instrument are recognized in accumulated other comprehensive income (loss). Amounts associated with cash flow hedges are reclassified to cost of sales in the condensed consolidated statement of operations when the forecasted transaction occurs. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive income (loss) will be reclassified to other income (expense) in the current period. Changes in the fair value of the ineffective portion of derivative instruments are recognized in other income (expense) in the condensed consolidated statement of operations in the current period. We record the premium paid (time value) of an option on the date of purchase as an asset. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in other income (expense) over the life of the option contract. For the three and six months ended April 30, 2018 and 2017 ineffectiveness and gains and losses recognized in other income (expense) due to de-designation of cash flow hedge contracts were not significant.

In July 2012, Agilent executed treasury lock agreements for $400 million in connection with future interest payments to be made on our 2022 senior notes issued on September 10, 2012. We designated the treasury lock as a cash flow hedge. The treasury lock contracts were terminated on September 10, 2012 and we recognized a deferred gain in accumulated other comprehensive income which is being amortized to interest expense over the life of the 2022 senior notes. The remaining gain to be amortized related to the treasury lock agreements at April 30, 2018 was $1 million .

In February 2016, Agilent executed three forward-starting pay fixed/receive variable interest rate swaps for the notional amount of $300 million in connection with future interest payments to be made on our 2026 senior notes issued on September 15, 2016. These derivative instruments were designated and qualified as cash flow hedges under the criteria prescribed in the

authoritative guidance. The swap arrangements were terminated on September 15, 2016 with a payment of $10 million and we recognized this as a deferred loss in accumulated other comprehensive income which is being amortized to interest expense over the life of the 2026 senior notes. The remaining loss to be amortized related to the interest rate swap agreements at April 30, 2018 was $8 million .

Other Hedges

Additionally, we enter into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of our subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in value of the derivative are recognized in other income (expense) in the condensed consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities.

Our use of derivative instruments exposes us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We do, however, seek to mitigate such risks by limiting our counterparties to major financial institutions which are selected based on their credit ratings and other factors.  We have established policies and procedures for mitigating credit risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties.

A number of our derivative agreements contain threshold limits to the net liability position with counterparties and are dependent on our corporate credit rating determined by the major credit rating agencies. The counterparties to the derivative instruments may request collateralization, in accordance with derivative agreements, on derivative instruments in net liability positions.

The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position as of April 30, 2018 , was $5 million . The credit-risk-related contingent features underlying these agreements had not been triggered as of April 30, 2018 .

There were 110 foreign exchange forward contracts open as of April 30, 2018 and designated as cash flow hedges.

The aggregated notional amounts by currency and designation as of April 30, 2018 were as follows:

Derivative instruments are subject to master netting arrangements and are disclosed gross in the balance sheet in accordance with the authoritative guidance. The gross fair values and balance sheet location of derivative instruments held in the consolidated balance sheet as of April 30, 2018 and October 31, 2017 were as follows:

The effect of derivative instruments for foreign exchange contracts designated as hedging instruments and not designated as hedging instruments in our consolidated statement of operations were as follows:

At April 30, 2018 , the estimated amount of existing net gain that is expected to be reclassified from accumulated other comprehensive income (loss) to cost of sales within the next twelve months is $2 million .

10. RETIREMENT PLANS AND POST RETIREMENT PENSION PLANS

Components of net periodic costs. For the three and six months ended April 30, 2018 and 2017 , our net pension and post retirement benefit costs were comprised of the following:

We made no contributions to our U.S. defined benefit plans during the three and six months ended April 30, 2018 . We contributed $5 million and $11 million to our non-U.S. defined benefit plans during the three and six months ended April 30, 2018 , respectively.

We contributed $25 million to our U.S. defined benefit plans during the three and six months ended April 30, 2017 . We contributed $6 million and $9 million to our non-U.S. defined benefit plans during the three and six months ended April 30, 2017 , respectively.

We do not expect to contribute to our U.S. defined benefit plans during the remainder of 2018 and we expect to contribute $12 million to our non-U.S. defined benefit plans during the remainder of 2018 .

Japanese Welfare Pension Insurance Law . In Japan, Agilent has employees' pension fund plans, which are defined benefit pension plans established under the Japanese Welfare Pension Insurance Law (JWPIL). The plans are composed of (a) a substitutional portion based on the pay-related part of the old-age pension benefits prescribed by JWPIL (similar to social security benefits in the United States) and (b) a corporate portion based on a contributory defined benefit pension arrangement established at the discretion of the company. During the six months ended April 30, 2017 , Agilent received government approval and returned the substitutional portion of Japan's pension plan to the Japanese government, as allowed by the JWPIL. The initial transfer resulted in a net gain of $32 million which was recorded within cost of sales and operating expenses in the condensed consolidated statement of operations. The net gain consisted of two parts - a gain of $41 million , representing the difference between the fair values of the Accumulated Benefit Obligation (ABO) settled of $65 million and the assets transferred from the pension trust to the government of Japan of $24 million , offset by a settlement loss of $9 million related to the recognition of previously unrecognized actuarial losses included in accumulated other comprehensive income. In the first quarter of fiscal year 2018, after the Japanese government's final review of our initial payment, we received a refund of $5.2 million which was recorded as a settlement gain.

11. WARRANTIES AND CONTINGENCIES

Warranties

We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product shipments. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost estimates. Estimated warranty charges are recorded within cost of products at the time products are sold. The standard warranty accrual balances are held in other accrued and other long-term liabilities on our condensed consolidated balance sheet. Our standard warranty terms typically extend to one year from the date of delivery, depending on the product.

A summary of the standard warranty accrual activity is shown in the table below:

Contingencies

We are involved in lawsuits, claims, investigations and proceedings, including, but not limited to, intellectual property, commercial and employment matters, which arise in the ordinary course of business. There are no matters pending that we currently believe are probable and reasonably possible of having a material impact to our business, consolidated financial condition, results of operations or cash flows.

12. SHORT-TERM DEBT

Credit Facilities

On September 15, 2014 , Agilent entered into a credit agreement with a group of financial institutions which provides for a $400 million five -year unsecured credit facility that will expire on September 15, 2019 . On June 9, 2015, the commitments under the existing credit facility were increased by $300 million and on July 14, 2017, the commitments under the existing credit facility were increased by an additional $300 million so that the aggregate commitments under the facility now total $1 billion . As of April 30, 2018 , the company had borrowings of $315 million outstanding under the credit facility. We were in compliance with the covenants for the credit facility during the three and six months ended April 30, 2018 . In May 2018, the outstanding balance under our existing credit facility was paid in full.

2017 Senior Notes

In  October 2007 , the company issued an aggregate principal amount of  $600 million  in senior notes ("2017 senior notes"). On October 20, 2014, we settled the redemption of  $500 million  of the  $600 million  outstanding aggregate principal amount of our 2017 senior notes. The remaining $100 million in senior notes matured on November 1, 2017 and were paid in full.
