1. Basis of Presentation and Accounting Policies

In the opinion of management of Rockwell Automation, Inc. ("Rockwell Automation" or "the Company"), the unaudited Condensed Consolidated Financial Statements contain all adjustments necessary to present fairly the financial position, results of operations and cash flows for the periods presented and, except as otherwise indicated, such adjustments consist only of those of a normal, recurring nature. These statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. The results of operations for the three and nine-month periods ended June 30, 2018, are not necessarily indicative of the results for the full year. All date references to years and quarters herein refer to our fiscal year and fiscal quarter unless otherwise stated.

Receivables

Receivables are stated net of an allowance for doubtful accounts of $19.7 million at June 30, 2018, and $24.9 million at September 30, 2017. In addition, receivables are stated net of an allowance for certain customer returns, rebates and incentives of $7.8 million at June 30, 2018, and $11.9 million at September 30, 2017.

Earnings Per Share

The following table reconciles basic and diluted earnings per share (EPS) amounts (in millions, except per share amounts):

	Three Months Ended June 30,						Nine Months Ended June 30,
	2018			2017			2018			2017

Basic	$	1.60		$	1.69		$	1.50		$	4.83
Diluted	$	1.58		$	1.67		$	1.48		$	4.77

For each of the three and nine months ended June 30, 2018, 0.9 million shares related to share-based compensation awards were excluded from the diluted EPS calculation because they were antidilutive. For the three and nine months ended June 30, 2017, 0.6 million and 0.8 million shares, respectively, related to share-based compensation awards were excluded from the diluted EPS calculation because they were antidilutive.

Non-Cash Investing and Financing Activities

Capital expenditures of $13.4 million and $22.3 million were accrued within accounts payable and other current liabilities at June 30, 2018 and 2017, respectively. At June 30, 2018 and 2017, there were $22.6 million and $3.4 million, respectively, of outstanding common stock share repurchases recorded in accounts payable that did not settle until the next fiscal quarter. These non-cash investing and financing activities have been excluded from cash used for capital expenditures and treasury stock purchases in the Condensed Consolidated Statement of Cash Flows.

Recent Accounting Pronouncements

In March 2017, the FASB issued a new standard regarding the presentation of net periodic pension and postretirement benefit costs. This standard requires the service cost component to be reported in the income statement in the same line item as other compensation costs arising from services rendered by the related employees during the period. The other components of net periodic benefit cost are required to be presented separately from the service cost component in either a separate line item or within another appropriate line item with disclosure of where those costs are recorded. This standard also requires that only the service cost component is eligible for capitalization, when applicable. This standard is effective for us for reporting periods starting October 1, 2018. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued a new standard on accounting for leases that requires lessees to recognize right-of-use assets and lease liabilities for most leases, among other changes to existing lease accounting guidance. The new standard also requires additional qualitative and quantitative disclosures about leasing activities. This standard is effective for us for reporting periods beginning October 1, 2019. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In May 2014, the FASB issued a new standard on revenue recognition related to contracts with customers. This standard supersedes nearly all existing revenue recognition guidance and involves a five-step principles-based approach to recognizing revenue. The underlying principle is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The new standard will also require additional qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract. We will adopt this new standard under the modified retrospective method in the first quarter of fiscal 2019, with the cumulative effect of initially applying the guidance recognized in retained earnings at the adoption date.

We have established a project plan and a cross-functional implementation team to adopt the new revenue standard. We are in the process of identifying and implementing necessary changes to accounting policies, processes, controls and systems to enable compliance with this new standard. We continue to evaluate the impact the adoption of this standard will have on our consolidated financial statements and related disclosures. Although we do not expect the effect of changes to our accounting for revenue and contract costs to be significant, we do expect the impacts will include changes to the timing of revenue currently recognized under the completed contract method, changes to the timing of revenue from software licenses bundled with services, and the capitalization of certain contract costs. We do expect an increase in qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract.

8. Investments

We record investments in fixed income and equity securities, classified as available-for-sale investments or trading investments, at fair value.

Available-for-sale Investments

We invest in certificates of deposit, time deposits, commercial paper and other fixed income securities which were classified as available-for-sale as of June 30, 2018, and September 30, 2017. Unrealized gains and losses on available-for-sale investments are included in our Condensed Consolidated Balance Sheet as a component of accumulated other comprehensive loss, net of any deferred taxes. Realized gains and losses are included in net income.

Our available-for-sale investments consist of (in millions):

	June 30, 2018		September 30, 2017
Certificates of deposit and time deposits	$	477.9	$	1,005.3
Commercial paper	—		20.3
Corporate debt securities	160.3		199.4
Government securities	65.8		116.8
Asset-backed securities	30.0		45.8
Total	$	734.0	$	1,387.6

Pre-tax gross unrealized gains and losses on available-for-sale investments were not material as of June 30, 2018. Pre-tax gross realized gains and losses on available-for-sale investments were not material for the three and nine months ended June 30, 2018. At June 30, 2018, there were no outstanding purchases of available-for-sale investments recorded in accounts payable.

We evaluated all available-for-sale investments for which the fair value was less than amortized cost for impairment on an individual security basis at June 30, 2018. This assessment included consideration of our intent and ability to hold the security and the credit risks specific to each security. We determined that the declines in fair value of these investments were not other than temporary as of June 30, 2018, and accordingly we did not recognize any impairment charges in net income.

The table below summarizes the contractual maturities of our investments as of June 30, 2018 (in millions). Actual maturities may differ from the contractual maturities below as borrowers may have the right to prepay certain obligations.

	Fair Value
Less than one year	$	548.6
Due in one to five years	185.4
Total	$	734.0

Classification of our available-for-sale investments as current or noncurrent is based on the nature of the investment and when the investment is reasonably expected to be realized. These investments were included in the following line items within the Condensed Consolidated Balance Sheet (in millions):

	June 30, 2018		September 30, 2017
Short-term investments	$	548.6	$	1,124.6

Trading Investments

On June 11, 2018, we entered into a Securities Purchase Agreement (the "Purchase Agreement") with PTC. PTC agreed to sell 10,582,010 shares of its common stock (the "Shares") to us in a private placement at a purchase price of $94.50 per share for an aggregate purchase price of approximately $1.0 billion. For a period of approximately 3 years after the closing of the Purchase Agreement transaction ("Closing") we are subject to entity-specific transfer restrictions subject to certain exceptions. Following the first anniversary of the Closing, the Company will be allowed to transfer Shares not exceeding, in the aggregate in any 90-day period, a number of Shares equal to up to 1.0% of PTC's total outstanding shares of common stock as of the first day in such 90-day period, but no more than 2.0% of PTC's total outstanding shares of common stock in each of the second year and the third year after the Closing.

The Purchase Agreement, which was a firm commitment as of June 11, 2018, was determined to be a forward contract which was recorded at fair value and designated as a trading security. For the three months ended June 30, 2018, losses of $76.8 million related to this forward contract were recorded in other (expense) income in the Condensed Consolidated Statement of Operations. The forward contract was valued using the difference between the purchase price of $94.50 per share of PTC common stock and the most recent closing price of PTC common stock quoted on Nasdaq, resulting in losses of $7.3 million, less a temporary discount for lack of marketability calculated using a put-option model, resulting in losses of $69.5 million. The discount is due to an instrument-specific restriction as the Shares will be issued as private placements but are contractually required to be registered by PTC under the Securities Act of 1933 within one year, at which time the discount will be reversed. As of June 30, 2018, a corresponding liability is recorded in other current liabilities in the Condensed Consolidated Balance Sheet.

On July 19, 2018, we completed the purchase of the Shares. The investment maintains the same classification as the forward contract, a trading security, and will be recorded at fair value, less a discount for lack of marketability, with any changes in fair value recorded to earnings.

Fair Value of Investments

U.S. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. U.S. GAAP also classifies the inputs used to measure fair value into the following hierarchy:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.

Level 3: Unobservable inputs for the asset or liability.

We recognize all available-for-sale and trading investments at fair value in the Condensed Consolidated Balance Sheet. The valuation methodologies used for our investments measured at fair value are described as follows.

Certificates of deposit and time deposits — These investments are stated at cost, which approximates fair value.

Commercial paper — These investments are stated at amortized cost, which approximates fair value.

Corporate debt securities — Valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flow approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

Government securities — Valued at the most recent closing price on the active market on which the individual securities are traded or, absent an active market, utilizing observable inputs such as closing prices in less frequently traded markets.

Asset-backed securities — Valued using a discounted cash flow approach that maximizes observable inputs, such as current yields of benchmark instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

Forward contract — Valued using the difference between the PTC purchase price of $94.50 per share of PTC common stock and the most recent closing price of PTC common stock quoted on Nasdaq, less a temporary discount for lack of marketability. The discount for lack of marketability, which will reverse upon registration of the PTC securities, is calculated using a put-option model which includes observable and unobservable inputs and is categorized as Level 3 in the fair value hierarchy. The primary inputs include historical and implied PTC common stock volatility and the restriction term.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. We did not have any transfers between levels of fair value measurements during the periods presented.

The loss of $96.1 million upon the agreement commencement date includes a loss of $28.1 million, resulting from the difference between the purchase price of $94.50 per share of PTC common stock and the June 11, 2018 closing price of PTC common stock, and a $68.0 million valuation adjustment pending registration of the PTC securities. The unrealized gain of $19.3 million includes a gain of $20.8 million, resulting from the appreciation of PTC common stock between the agreement commencement date and the end of the quarter, partially offset by a $1.5 million increase in the valuation adjustment associated with the appreciation of PTC’s common stock. The unrealized loss of $76.8 million at June 30, 2018 includes a $7.3 million loss on investment and a $69.5 million valuation adjustment.

11. Commitments and Contingent Liabilities

Various lawsuits, claims and proceedings have been or may be instituted or asserted against us relating to the conduct of our business, including those pertaining to product liability, environmental, safety and health, intellectual property, employment and contract matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, we believe the disposition of matters that are pending or have been asserted will not have a material effect on our business, financial condition or results of operations.

We (including our subsidiaries) have been named as a defendant in lawsuits alleging personal injury as a result of exposure to asbestos that was used in certain components of our products many years ago. Currently there are a few thousand claimants in lawsuits that name us as defendants, together with hundreds of other companies. In some cases, the claims involve products from divested businesses, and we are indemnified for most of the costs. However, we have agreed to defend and indemnify asbestos claims associated with products manufactured or sold by our former Dodge mechanical and Reliance Electric motors and motor repair services businesses prior to their divestiture by us, which occurred on January 31, 2007. We are also responsible for half of the costs and liabilities associated with asbestos cases against the former Rockwell International Corporation’s divested measurement and flow control business. But in all cases, for those claimants who do show that they worked with our products or products of divested businesses for which we are responsible, we nevertheless believe we have meritorious defenses, in substantial part due to the integrity of the products, the encapsulated nature of any asbestos-containing components, and the lack of any impairing medical condition on the part of many claimants. We defend those cases vigorously. Historically, we have been dismissed from the vast majority of these claims with no payment to claimants.

We have maintained insurance coverage that we believe covers indemnity and defense costs, over and above self-insured retentions, for claims arising from our former Allen-Bradley subsidiary. Our insurance carrier entered into a cost share agreement with us to pay the substantial majority of future defense and indemnity costs for Allen-Bradley asbestos claims. We believe that this arrangement will continue to provide coverage for Allen-Bradley asbestos claims throughout the remaining life of the asbestos liability.

We also have rights to historic insurance policies that provide indemnity and defense costs, over and above self-insured retentions, for claims arising out of certain asbestos liabilities relating to the divested measurement and flow control business. We initiated litigation against several insurers to pursue coverage for these claims, subject to each carrier's policy limits, and the case is now pending in Los Angeles County Superior Court. In September 2016, we entered into settlement agreements with certain insurance company defendants, and we continue to pursue our claims against the remaining defendants. We believe these settlement agreements will continue to provide partial coverage for these asbestos claims throughout the remaining life of asbestos liability.

The uncertainties of asbestos claim litigation make it difficult to predict accurately the ultimate outcome of asbestos claims. That uncertainty is increased by the possibility of adverse rulings or new legislation affecting asbestos claim litigation or the settlement process. Subject to these uncertainties and based on our experience defending asbestos claims, we do not believe these lawsuits will have a material effect on our business, financial condition or results of operations.

We have, from time to time, divested certain of our businesses. In connection with these divestitures, certain lawsuits, claims and proceedings may be instituted or asserted against us related to the period that we owned the businesses, either because we agreed to retain certain liabilities related to these periods or because such liabilities fall upon us by operation of law. In some instances, the divested business has assumed the liabilities; however, it is possible that we might be responsible for satisfying those liabilities if the divested business is unable to do so.

In connection with the spin-offs of our former automotive business, semiconductor systems business and avionics and communications business, the spun-off companies have agreed to indemnify us for substantially all contingent liabilities related to the respective businesses, including environmental and intellectual property matters.

In conjunction with the sale of our Dodge mechanical and Reliance Electric motors and motor repair services businesses, we agreed to indemnify Baldor Electric Company for costs and damages related to certain legal, legacy environmental and asbestos matters of these businesses arising before January 31, 2007, for which the maximum exposure would be capped at the amount received for the sale.

11. Commitments and Contingent Liabilities (continued)

In many countries we provide a limited intellectual property indemnity as part of our terms and conditions of sale. We also at times provide limited intellectual property indemnities in other contracts with third parties, such as contracts concerning the development and manufacture of our products. As of June 30, 2018, we were not aware of any material indemnification claims where an unfavorable outcome was probable or reasonably possible. Historically, claims that have been made under the indemnification agreements have not had a material impact on our business, financial condition or results of operations; however, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our business, financial condition or results of operations in a particular period.

12. Income Taxes

At the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur.

Our base rate reflects a change in the U.S. federal statutory rate from 35 percent to 21 percent resulting from the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) on December 22, 2017. The rate change was effective for us at the beginning of our fiscal year, using a blended rate for the annual period. As a result, the blended statutory tax rate for our fiscal year 2018 is 24.53 percent.

The effective tax rate was 21.1 percent and 77.7 percent in the three and nine months ended June 30, 2018, respectively, compared to 21.4 percent and 18.7 percent in the three and nine months ended June 30, 2017, respectively. The effective tax rate was lower than the U.S. statutory rate of 24.53 percent in the three months ended June 30, 2018, primarily because we benefited from lower non-U.S. tax rates and also realized a benefit from discrete tax items, partially offset by the PTC investment adjustments without a corresponding tax benefit. The effective tax rate was higher than the U.S. statutory rate of 24.53 percent in the nine months ended June 30, 2018, due to provisional tax expense ($483.7 million or 57.0 percent) resulting from the Tax Act. The effective tax rate was lower than the U.S. statutory rate of 35 percent in the three and nine months ended June 30, 2017, primarily because we benefited from lower non-U.S. tax rates, and we also realized a benefit from discrete tax items.

Provisional Amounts

The Tax Act requires us to revalue our existing U.S. deferred tax balance to reflect the lower statutory tax rate and pay a one-time tax on earnings of certain foreign subsidiaries that were previously deferred from U.S. tax (“transition tax”). At June 30, 2018, we have not completed our accounting for the tax effects of the Tax Act; however, we have made reasonable estimates of its effects on our existing U.S. deferred tax balance and the transition tax and recorded provisional amounts which are included as a component of income tax expense from continuing operations, as discussed in more detail below.

We revalued our U.S. deferred tax assets and liabilities based on the rate at which they are expected to reverse in the future, which is either 24.53 percent for reversals in 2018 or 21 percent for reversals in 2019 and subsequent years. However, we are still analyzing certain aspects of the Tax Act and refining our calculations, which could potentially affect the valuation of these balances or potentially give rise to new deferred tax amounts. We have recorded a provisional amount of $94.2 million in the nine months ended June 30, 2018, of which the entire amount was recorded in the three months ended December 31, 2017.

The Tax Act requires the transition tax to be computed based on our total post-1986 earnings and profits (“E&P”) at December 31, 2017, that were previously deferred from U.S. income tax. As a result, we are required to make reasonable estimates given our September 30 fiscal year. We have recorded a provisional benefit of $7.5 million and provisional expense of $389.5 million for the transition tax liability for all of our foreign subsidiaries in the three and nine months ended June 30, 2018, respectively. At June 30, 2018, we have recorded income taxes payable of $389.5 million related to the transition tax in the Condensed Consolidated Balance Sheet, of which $34.1 million is recorded within other current liabilities, and $355.4 million is recorded within other liabilities because that portion is payable greater than twelve months after June 30, 2018.

12. Income Taxes (continued)

The transition tax is applied to the balance of post-1986 E&P at rates of 15.5 percent for cash assets (as defined in the Tax Act) and 8 percent for non-cash assets measured at the higher of the balance at September 30, 2018, or the average of the ending balances at September 30, 2016, and September 30, 2017. Our reasonable estimates will change as a result of adjustments impacting E&P, and distributions and other transactions impacting cash. The Company anticipates that it will complete its accounting for the transition tax at December 31, 2018. These uncertainties form the basis for the Company’s provisional reporting based upon reasonable estimates at June 30, 2018.

The Company has historically accounted for the earnings of its foreign subsidiaries as being indefinitely reinvested under ASC 740-30. As a result of the broad changes to the U.S. international tax system under the Tax Act, the Company will begin to account for substantially all of its non-U.S. subsidiaries as being immediately subject to tax other than in certain limited circumstances. The Company has provided for taxes on the balance of historic and current earnings that may be subject to foreign withholding and U.S. state taxes. For future distributions related to historic earnings, we recorded deferred tax liabilities of $59.8 million related to foreign withholding taxes, and deferred tax assets of $59.8 million related to foreign tax credits attributable to the foreign withholding taxes. These provisional amounts are presented net within deferred income tax assets in the Condensed Consolidated Balance Sheet as of June 30, 2018.  We have not yet completed our assessment of whether a portion of these assets and liabilities should be presented as gross amounts.

Unrecognized Tax Benefits

The amount of gross unrecognized tax benefits was $19.4 million and $31.1 million at June 30, 2018, and September 30, 2017, respectively, of which the entire amount would reduce our effective tax rate if recognized.

Accrued interest and penalties related to unrecognized tax benefits were $3.7 million and $4.0 million at June 30, 2018, and September 30, 2017, respectively. We recognize interest and penalties related to unrecognized tax benefits in the income tax provision.

We believe it is reasonably possible that the amount of gross unrecognized tax benefits could be reduced by up to $5.1 million in the next 12 months as a result of the resolution of tax matters in various global jurisdictions and the lapses of statutes of limitations. If all of the unrecognized tax benefits were recognized, the net reduction to our income tax provision, including the recognition of interest and penalties and offsetting tax assets, could be up to $4.5 million.

We conduct business globally and are routinely audited by the various tax jurisdictions in which we operate. We are no longer subject to U.S. federal income tax examinations for years before 2016 and are no longer subject to state, local and foreign income tax examinations for years before 2003.

Among other considerations, we evaluate performance and allocate resources based upon segment operating earnings before income taxes, costs related to the unsolicited Emerson proposals in the first quarter of fiscal 2018, interest expense, costs related to corporate offices, non-operating pension costs, certain corporate initiatives, gains and losses on investments, valuation adjustment pending registration of PTC securities, gains and losses from the disposition of businesses, and purchase accounting depreciation and amortization. We incurred $11.2 million of third-party advisory fees in connection with our evaluation of unsolicited Emerson acquisition proposals in the first quarter of 2018. Depending on the product, intersegment sales within a single legal entity are either at cost or cost plus a mark-up, which does not necessarily represent a market price. Sales between legal entities are at an appropriate transfer price. We allocate costs related to shared segment operating activities to the segments using a methodology consistent with the expected benefit.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareowners of

Rockwell Automation, Inc.

Milwaukee, Wisconsin

We have reviewed the accompanying condensed consolidated balance sheet of Rockwell Automation, Inc. and subsidiaries (the “Company”) as of June 30, 2018, and the related condensed consolidated statements of operations and comprehensive income for the three-month and nine-month periods ended June 30, 2018 and 2017, and of cash flows for the nine-month periods ended June 30, 2018 and 2017. These condensed consolidated interim financial statements are the responsibility of the Company’s management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Rockwell Automation, Inc. and subsidiaries as of September 30, 2017, and the related consolidated statements of operations, comprehensive income, cash flows, and shareowners’ equity for the year then ended (not presented herein); and in our report dated November 15, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of September 30, 2017 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

ROCKWELL AUTOMATION, INC.

Overview

Rockwell Automation, Inc., a leader in industrial automation and information, makes its customers more productive and the world more sustainable. Overall demand for our products, solutions and services is driven by:

• investments in manufacturing, including upgrades, modifications and expansions of existing facilities or production lines and new facilities or production lines;

• investments in basic materials production capacity, which may be related to commodity pricing levels;

• our customers’ needs for faster time to market, lower total cost of ownership, improved asset utilization and optimization, and enterprise risk management;

• our customers’ needs to continuously improve quality, safety and sustainability;

• industry factors that include our customers’ new product introductions, demand for our customers’ products or services, and the regulatory and competitive environments in which our customers operate;

• levels of global industrial production and capacity utilization;

• regional factors that include local political, social, regulatory and economic circumstances; and

• the spending patterns of our customers due to their annual budgeting processes and their working schedules.

Long-term Strategy

Our strategy is to bring The Connected Enterprise to life. We integrate control and information across the enterprise to help industrial companies and their people be more productive. Our vision of being the most valued global provider of innovative industrial automation and information products, solutions and services is supported by our growth and performance strategy, which seeks to:

• achieve organic sales growth in excess of the automation market by expanding our served market and strengthening our competitive differentiation;

• diversify our sales streams by broadening our portfolio of products, solutions and services, expanding our global presence and serving a wider range of industries and applications;

• grow market share by gaining new customers and by capturing a larger share of existing customers’ spending;

• enhance our market access by building our channel capability and partner network;

• acquire companies that serve as catalysts to organic growth by adding complementary technology, expanding our served market, or enhancing our domain expertise or market access;

• deploy human and financial resources to strengthen our technology leadership and our intellectual capital business model;

• continuously improve quality and customer experience; and

• drive annual cost productivity.

By implementing the above strategy, we seek to achieve our long-term financial goals, including above-market organic sales growth, EPS growth above sales growth, return on invested capital in excess of 20 percent and free cash flow equal to about 100 percent of Adjusted Income. We expect acquisitions to add a percentage point or more per year, on average, to long-term sales growth.

U.S. Industrial Economic Trends

In the third quarter of 2018, sales in the U.S. accounted for 54 percent of our total sales. The various indicators we use to gauge the direction and momentum of our served U.S. markets include:

• The Industrial Production (IP) Index, published by the Federal Reserve, which measures the real output of manufacturing, mining and electric and gas utilities. The IP Index is expressed as a percentage of real output in a base year, currently 2012. Historically, there has been a meaningful correlation between the changes in the IP Index and the level of automation investment made by our U.S. customers in their manufacturing base.

• The Manufacturing Purchasing Managers’ Index (PMI), published by the Institute for Supply Management (ISM), which indicates the current and near-term state of manufacturing activity in the U.S. According to the ISM, a PMI measure above 50 indicates that the U.S. manufacturing economy is generally expanding while a measure below 50 indicates that it is generally contracting.

• Industrial Equipment Spending, compiled by the Bureau of Economic Analysis, which provides insight into spending trends in the broad U.S. industrial economy. This measure over the longer term has proven to demonstrate a reasonable correlation with our domestic growth.

• Capacity Utilization (Total Industry), published by the Federal Reserve, which measures plant operating activity. Historically, there has been a meaningful correlation between Capacity Utilization and levels of U.S. IP.

The table below depicts trends in these indicators since the quarter ended September 2016. In the third quarter of fiscal 2018, all of these U.S. economic indicators, except Industrial Equipment Spending, improved compared to the prior quarter. Industrial Equipment Spending did increase compared to the same quarter in the prior fiscal year.

	IP Index	PMI	Industrial Equipment Spending (in billions)	Capacity Utilization (percent)
Fiscal 2018 quarter ended:
June 2018	107.5	60.2	242.1	77.9
March 2018	105.9	59.3	243.9	77.2
December 2017	105.3	59.3	238.5	77.0
Fiscal 2017 quarter ended:
September 2017	103.3	60.2	234.6	75.8
June 2017	103.7	56.7	230.1	76.2
March 2017	102.5	56.6	222.1	75.4
December 2016	102.2	54.3	218.1	75.3
Fiscal 2016 quarter ended:
September 2016	102.0	51.4	215.3	75.2

Note: Economic indicators are subject to revision by the issuing organizations.

While we are optimistic that the impact of U.S. tax reform on our customers' investment decisions could benefit our future performance, it is too early to quantify any such benefits.

In March 2018, the U.S. Government imposed tariffs on steel and aluminum imports. While we have seen increases in the price of steel and aluminum as a result of these tariffs, we believe they will not have a material effect on our business, financial condition, or results of operations. 

The U.S. Government has also enacted tariffs and proposed others on certain imports from China.  In response to the U.S. Government actions, China, Canada, Mexico and the European Union have proposed or enacted tariffs on certain imports from the U.S.  There remains a lot of uncertainty about the particulars of these tariffs.  We continue to evaluate the impact the enacted and proposed tariffs will have on our business, as well as mitigation opportunities. For those tariffs that have been enacted, we do not believe they will have a material effect on our business, financial condition, or results of operations.

Non-U.S. Economic Trends

In the third quarter of 2018, sales to customers outside the U.S. accounted for 46 percent of our total sales. These customers include both indigenous companies and multinational companies with expanding global presence. In addition to the global factors previously mentioned in the "Overview" section, international demand, particularly in emerging markets, has historically been

26

ROCKWELL AUTOMATION, INC.

driven by the strength of the industrial economy in each region, investments in infrastructure and expanding consumer markets. We use changes in the respective countries' gross domestic product and industrial production as indicators of the growth opportunities in each region where we do business.

Recent industrial production forecasts continue to project growth in all regions for the remainder of fiscal 2018.  In Asia Pacific, credit tightening in China could result in slightly lower growth this calendar year, but India’s economic outlook continues to strengthen.  Presidential elections and trade agreement negotiations are creating some uncertainty in Latin America, and economic indicators in EMEA have weakened recently due to rising oil prices and a slowdown in foreign trade. However, both regions are still expected to report growth this year, despite these headwinds.

ROCKWELL AUTOMATION, INC.

Summary of Results of Operations

Sales in the third quarter of 2018increased6.2 percent compared to the third quarter of 2017. Organic sales increased5.7 percent year over year. Currency translation increased sales by 1.8 percentage points, and the prior year divestiture reduced sales growth by 1.3 percentage points. Organic sales growth in the quarter was driven by broad-based growth across regions and industries.

(1) See Note 13 in the Condensed Consolidated Financial Statements for the definition of segment operating earnings.

(2) Total segment operating earnings and total segment operating margin are non-GAAP financial measures. We exclude purchase accounting depreciation and amortization, general corporate – net, non-operating pension costs, costs related to the unsolicited Emerson proposals in the first quarter of fiscal 2018, gains and losses on investments, valuation adjustment pending registration of PTC securities, interest expense and income tax provision because we do not consider these costs to be directly related to the operating performance of our segments. We believe that these measures are useful to investors as measures of operating performance. We use these measures to monitor and evaluate the profitability of our Company. Our measures of total segment operating earnings and total segment operating margin may be different from those used by other companies.

(3) Adjusted EPS is a non-GAAP earnings measure that excludes the non-operating pension costs and their related income tax effects. See Adjusted Income, Adjusted EPS and Adjusted Effective Tax Rate Reconciliation for more information on this non-GAAP measure.

29

ROCKWELL AUTOMATION, INC.

Purchase accounting depreciation and amortization and non-operating pension costs are not allocated to our operating segments because these costs are excluded from our measurement of each segment's operating performance for internal purposes. If we were to allocate these costs, we would attribute them to each of our segments as follows (in millions):

	Three Months Ended June 30,				Nine Months Ended June 30,
	2018		2017		2018		2017
Purchase accounting depreciation and amortization
Architecture & Software	$	1.6	$	1.6	$	4.9	$	4.8
Control Products & Solutions	2.6		3.7		7.6		11.2
Non-operating pension costs
Architecture & Software	1.8		7.1		5.3		21.3
Control Products & Solutions	2.8		11.1		8.3		33.3

The decreases in non-operating pension costs in both segments for the three and nine months ended June 30, 2018, were primarily due to a $200 million voluntary contribution in fiscal 2017 and other actuarial adjustments.

30

ROCKWELL AUTOMATION, INC.

Adjusted Income, Adjusted EPS and Adjusted Effective Tax Rate Reconciliation

Adjusted Income, Adjusted EPS and Adjusted Effective Tax Rate are non-GAAP earnings measures that exclude non-operating pension costs, costs related to the unsolicited Emerson proposals in the first quarter of fiscal 2018, gains and losses on investments, and valuation adjustment pending registration of PTC securities, including their respective tax effects, and the provisional tax effects of deemed repatriation of foreign earnings and the revaluation of net deferred tax assets due to the enactment of the Tax Act.

We believe that Adjusted Income, Adjusted EPS and Adjusted Effective Tax Rate provide useful information to our investors about our operating performance and allow management and investors to compare our operating performance period over period. Adjusted EPS is also used as a financial measure of performance for our annual incentive compensation. Our measures of Adjusted Income, Adjusted EPS and Adjusted Effective Tax Rate may be different from measures used by other companies. These non-GAAP measures should not be considered a substitute for income from continuing operations, diluted EPS and effective tax rate.

Non-operating pension costs include defined benefit plan interest cost, expected return on plan assets, amortization of actuarial gains and losses and the impact of any plan curtailments or settlements. These components of net periodic pension cost primarily relate to changes in pension assets and liabilities that are a result of market performance; we consider these and other excluded costs to be unrelated to the operating performance of our business.

The following are the components of operating and non-operating pension costs (in millions):

	Three Months Ended June 30,						Nine Months Ended June 30,
	2018			2017			2018			2017
Service cost	$	22.2		$	24.2		$	66.8		$	72.5

Income before Income Taxes

Income before income taxes decreased9 percent and 11 percent year over year in the three and nine months ended June 30, 2018, respectively. The decrease in income before income taxes were primarily due to the PTC adjustments. Total segment operating earnings increased14 percent in each of the three and nine months ended June 30, 2018. The increases in total segment operating earnings were primarily due to higher sales.

Income Taxes

The effective tax rate for the three months endedJune 30, 2018, was 21.1 percent compared to 21.4 percent for the three months endedJune 30, 2017. The decrease in the effective tax rate was primarily due to the impact of the lower U.S. statutory tax rate under the Tax Act and a provisional benefit of $7.5 million related to the Tax Act in the quarter, partially offset by the PTC investment adjustments without a corresponding tax benefit. Our Adjusted Effective Tax Rate for the three months endedJune 30, 2018 was 18.7 percent compared to 22.4 percent for the three months endedJune 30, 2017. The decrease in the Adjusted Effective Tax Rate was primarily due to the impact of the lower U.S. statutory rate under the Tax Act. Refer to Note 12 in the Condensed Consolidated Financial Statements for further information regarding the effect of the enactment of the Tax Act on our financial condition and results of operations.

The effective tax rate for the nine months endedJune 30, 2018, was 77.7 percent compared to 18.7 percent for the nine months endedJune 30, 2017. The increase in the effective tax rate was due to provisional tax expense related to the transition tax on the deemed repatriation of foreign earnings ($389.5 million or 45.9 percent) and the revaluation of net deferred tax assets ($94.2 million or 11.1 percent) resulting from the Tax Act. Our Adjusted Effective Tax Rate for the nine months endedJune 30, 2018, was 19.3 percent compared to 20.0 percent for the nine months endedJune 30, 2017. The decrease in the Adjusted Effective Tax Rate was primarily due to the lower U.S. statutory tax rate under the Tax Act, partially offset by lower discrete tax items in the current year. Refer to Note 12 in the Condensed Consolidated Financial Statements for further information regarding the effect of the enactment of the Tax Act on our financial condition and results of operations.

Financial Condition

The following is a summary of our cash flows from operating, investing and financing activities, as reflected in the Condensed Consolidated Statement of Cash Flows (in millions):

	Nine Months Ended June 30,
	2018			2017
Cash (used for) provided by:
Operating activities	$	937.2		$	927.1
Investing activities	561.9			(363.7		)
Financing activities	(1,940.5		)	(537.7		)
Effect of exchange rate changes on cash	(29.4		)	(2.7		)
Cash (used for) provided by continuing operations	$	(470.8	)	$	23.0

The following table summarizes free cash flow (in millions), which is a non-GAAP financial measure:

	Nine Months Ended June 30,
	2018			2017
Cash provided by operating activities	$	937.2		$	927.1
Capital expenditures	(78.6		)	(97.5		)
Free cash flow	$	858.6		$	829.6

Our definition of free cash flow takes into consideration capital investments required to maintain our businesses' operations and execute our strategy. Cash provided by continuing operating activities adds back non-cash depreciation expense to earnings but does not reflect a charge for necessary capital expenditures. Our definition of free cash flow excludes the operating cash flows and capital expenditures related to our discontinued operations, if any. Operating, investing and financing cash flows of our discontinued operations, if any, are presented separately in our Condensed Consolidated Statement of Cash Flows. In our opinion, free cash flow provides useful information to investors regarding our ability to generate cash from business operations that is available for acquisitions and other investments, service of debt principal, dividends and share repurchases. We use free cash flow, as defined, as one measure to monitor and evaluate our performance, including as a financial measure for our annual incentive compensation. Our definition of free cash flow may differ from definitions used by other companies.

Cash provided by operating activities was $937.2 million for the nine months ended June 30, 2018, compared to $927.1 million for the nine months ended June 30, 2017. Free cash flow was $858.6 million for the nine months ended June 30, 2018, compared to $829.6 million for the nine months ended June 30, 2017. The year over year increases in cash provided by operating activities and free cash flow were primarily due to an increase in pre-tax income, partially offset by higher incentive compensation payments in the first nine months of fiscal 2018 compared to the first nine months of fiscal 2017.

We repurchased approximately 6.1 million shares of our common stock under our share repurchase program in the first nine months of 2018. The total cost of these shares was $1,104.4 million, of which $22.6 million was recorded in accounts payable at June 30, 2018, related to share repurchases that did not settle until July 2018. We had no unsettled share repurchases outstanding at September 30, 2017. We repurchased approximately 2.1 million shares of our common stock in the first nine months of 2017. The total cost of these shares was $302.1 million, of which $3.4 million was recorded in accounts payable at June 30, 2017, related to share repurchases that did not settle until July 2017. On June 11, 2018, we increased our share repurchase target for fiscal year 2018 to $1.5 billion. This represents a $300 million increase from our previous plan to repurchase $1.2 billion in fiscal year 2018. Our decision to repurchase shares in the remainder of 2018 will depend on business conditions, free cash flow generation, other cash requirements (including acquisitions) and stock price. At June 30, 2018, we had approximately $504.0 million remaining for share repurchases under the $1.0 billion share repurchase authorization approved by the Board of Directors on January 15, 2018. See Part II, Item 2, Unregistered Sales of Equity Securities and Use of Proceeds, for additional information regarding share repurchases.

ROCKWELL AUTOMATION, INC.

Financial Condition (continued)

We expect future uses of cash to include working capital requirements, capital expenditures, additional contributions to our retirement plans, acquisitions of businesses, dividends to shareowners, repurchases of common stock, repayments of debt, and the investment in PTC. We expect to fund future uses of cash with a combination of existing cash balances and short-term investments, cash generated by operating activities, commercial paper borrowings or a new issuance of debt or other securities. On July 19, 2018, we completed the purchase of the PTC Shares. In connection with the purchase, we issued approximately $675 million of commercial paper at a weighted average interest rate of 2.19 percent.

At September 30, 2017, substantially all of our cash, cash equivalents and investments (funds) were held by non-U.S. subsidiaries where our undistributed earnings were indefinitely reinvested. Due to the enactment of the Tax Act in the first quarter of fiscal 2018, our previously undistributed foreign earnings were subject to a transition tax of approximately $389.5 million. Accordingly, these funds will not be subject to further U.S. tax if repatriated. Refer to Note 12 in the Condensed Consolidated Financial Statements for further information regarding the effect of the enactment of the Tax Act on our financial condition and results of operations.

In the first nine months of fiscal year 2018, we repatriated $1.6 billion to the U.S. from our foreign subsidiaries.  The repatriated funds were primarily used to repurchase shares and repay outstanding commercial paper and long-term debt.  The source of these funds was cash and cash equivalents and from the liquidation of short and long-term investments.  Withholding and other taxes due as a result of the repatriation of these funds are not material. We anticipate repatriating additional amounts over the remainder of the fiscal year. 

In addition to cash generated by operating activities, we have access to existing financing sources, including the public debt markets and unsecured credit facilities with various banks. Our short-term debt obligations are primarily comprised of commercial paper borrowings. At June 30, 2018, we had no commercial paper borrowings outstanding. Commercial paper borrowings outstanding were $350.0 million at September 30, 2017, with a weighted average interest rate of 1.26 percent and weighted average maturity period of 10 days.

At June 30, 2018, and September 30, 2017, our total current borrowing capacity under our unsecured revolving credit facility expiring in March 2020 was $1.0 billion. We can increase the aggregate amount of this credit facility by up to $350.0 million, subject to the consent of the banks in the credit facility. We did not borrow against this credit facility during the nine months ended June 30, 2018. Borrowings under this credit facility bear interest based on short-term money market rates in effect during the period the borrowings are outstanding. The terms of this credit facility contain covenants under which we agree to maintain an EBITDA-to-interest ratio of at least 3.0 to 1.0. The EBITDA-to-interest ratio is defined in an amendment to the credit facility as the ratio of consolidated EBITDA (as defined in the amendment) for the preceding four quarters to consolidated interest expense for the same period.

Separate short-term unsecured credit facilities of approximately $127.0 million at June 30, 2018, were available to non-U.S. subsidiaries. Borrowings under our non-U.S. credit facilities at June 30, 2018 and 2017 were not significant. We were in compliance with all covenants under our credit facilities at June 30, 2018 and 2017. There are no significant commitment fees or compensating balance requirements under our credit facilities.

Among other uses, we can draw on our credit facility as a standby liquidity facility to repay our outstanding commercial paper as it matures. This access to funds to repay maturing commercial paper is an important factor in maintaining the short-term credit ratings set forth in the table below. Under our current policy with respect to these ratings, we expect to limit our other borrowings under our credit facility, if any, to amounts that would leave enough credit available under the facility so that we could borrow, if needed, to repay all of our then outstanding commercial paper as it matures.

The following is a summary of our credit ratings as of June 30, 2018:

Credit Rating Agency	Short-Term Rating	Long-Term Rating	Outlook
Standard & Poor’s	A-1	A	Stable
Moody’s	P-2	A3	Stable
Fitch Ratings	F1	A	Stable

ROCKWELL AUTOMATION, INC.

Financial Condition (continued)

Our ability to access the commercial paper market, and the related costs of these borrowings, is affected by the strength of our credit ratings and market conditions. We have not experienced any difficulty in accessing the commercial paper market to date. If our access to the commercial paper market is adversely affected due to a change in market conditions or otherwise, we would expect to rely on a combination of available cash and our unsecured committed credit facility to provide short-term funding. In such event, the cost of borrowings under our unsecured committed credit facility could be higher than the cost of commercial paper borrowings.

We regularly monitor the third-party depository institutions that hold our cash and cash equivalents and short-term investments. We diversify our cash and cash equivalents among counterparties to minimize exposure to any one of these entities. In February 2017, we began investing in investment-grade fixed income securities, including corporate debt and government obligations, to provide further diversification. Refer to Note 8 in the Condensed Consolidated Financial Statements for further discussion of these investments. Our emphasis is primarily on safety and liquidity of principal and secondarily on maximizing yield on those funds.

We use foreign currency forward exchange contracts to manage certain foreign currency risks. We enter into these contracts to hedge our exposure to foreign currency exchange rate variability in the expected future cash flows associated with certain third-party and intercompany transactions denominated in foreign currencies forecasted to occur within the next two years. We also use these contracts to hedge portions of our net investments in certain non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. In addition, we use foreign currency forward exchange contracts that are not designated as hedges to offset transaction gains or losses associated with some of our assets and liabilities resulting from intercompany loans or other transactions with third parties that are denominated in currencies other than our entities' functional currencies. Our foreign currency forward exchange contracts are usually denominated in currencies of major industrial countries. We diversify our foreign currency forward exchange contracts among counterparties to minimize exposure to any one of these entities.

Net gains and losses related to derivative forward exchange contracts designated as cash flow hedges offset the related gains and losses on the hedged items during the periods in which the hedged items are recognized in earnings.  During the three and nine months ended June 30, 2018, we reclassified $3.0 million and $15.0 million, respectively, in pre-tax net losses related to cash flow hedges from accumulated other comprehensive loss into the Condensed Consolidated Statement of Operations. During the three and nine months ended June 30, 2017, we reclassified $0.8 million and $2.3 million, respectively, in pre-tax net gains related to cash flow hedges from accumulated other comprehensive loss into the Condensed Consolidated Statement of Operations. We expect that approximately $2.2 million of pre-tax net unrealized gains on cash flow hedges as of June 30, 2018, will be reclassified into earnings during the next 12 months.

Information with respect to our contractual cash obligations is contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that at June 30, 2018, there has been no material change to this information, except regarding the repayment of our $250.0 million 5.65% notes, the transition tax required by the Tax Act, and the investment in PTC, as discussed in Note 5, Note 12, and Note 8, respectively, in the Condensed Consolidated Financial Statements.

Supplemental Sales Information

We translate sales of subsidiaries operating outside of the United States using exchange rates effective during the respective period. Therefore, changes in currency exchange rates affect our reported sales. Sales by acquired businesses also affect our reported sales. We believe that organic sales, defined as sales excluding the effects of changes in currency exchange rates and acquisitions, which is a non-GAAP financial measure, provides useful information to investors because it reflects regional and operating segment performance from the activities of our businesses without the effect of changes in currency exchange rates and acquisitions. We use organic sales as one measure to monitor and evaluate our regional and operating segment performance. We determine the effect of changes in currency exchange rates by translating the respective period’s sales using the same currency exchange rates that were in effect during the prior year. When we acquire businesses, we exclude sales in the current period for which there are no comparable sales in the prior period. When we divest a business, we exclude sales in the prior period for which there are no comparable sales in the current period. Organic sales growth is calculated by comparing organic sales to reported sales in the prior year, excluding divestitures. We attribute sales to the geographic regions based on the country of destination.

The following is a reconciliation of our reported sales by geographic region to organic sales (in millions):

Critical Accounting Estimates

We have prepared the Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States, which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. These estimates are based on our best judgment about current and future conditions, but actual results could differ from those estimates. Information with respect to accounting estimates that are the most critical to the understanding of our financial statements as they could have the most significant effect on our reported results and require subjective or complex judgments by management is contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that at June 30, 2018, there has been no material change to this information, except regarding the critical estimates involved in our accounting for the Tax Act as discussed in Note 12 in the Condensed Consolidated Financial Statements.

Environmental Matters

Information with respect to the effect of compliance with environmental protection requirements and resolution of environmental claims on us and our manufacturing operations is contained in Note 15 in the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that at June 30, 2018, there has been no material change to this information.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

Information with respect to our exposure to interest rate risk and foreign currency risk is contained in Item 7A, Quantitative and Qualitative Disclosures About Market Risk, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that at June 30, 2018, there has been no material change to this information.

Item 4. Controls and Procedures

Disclosure Controls and Procedures: We, with the participation of our Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)) as of the end of the fiscal quarter covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the fiscal quarter covered by this report, our disclosure controls and procedures were effective.

Internal Control Over Financial Reporting: There has not been any change in our internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) during the fiscal quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. In connection with our adoption of the new revenue recognition standard in the first quarter of fiscal 2019, we implemented additional functionality within our enterprise-wide information technology system during the second quarter of fiscal 2018. Though no changes were required to our enterprise-wide general information technology controls, key automated controls have been implemented and manual review controls have been enhanced to address the module's specific functionality. Additional enhancements and modifications to internal controls over financial reporting could be required during the remainder of fiscal 2018.

PART II. OTHER INFORMATION

Item 1.Legal Proceedings

Information with respect to our legal proceedings is contained in Item 3, Legal Proceedings, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that at June 30, 2018, there has been no material change to this information.

Item 1A.Risk Factors

Information about our most significant risk factors is contained in Item 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. We believe that there has been no material change to this information except as follows.

We own common stock in PTC Inc. and are exposed to the volatility, liquidity and other risks inherent in holding that stock.

We own common stock of PTC Inc. (PTC) that we acquired for an aggregate purchase price of approximately $1.0 billion. We present this investment on our Consolidated Balance Sheet at its fair value at the end of each reporting period, less a valuation adjustment pending registration of our shares of PTC common stock (Shares) under the Securities Act of 1933, which, per a registration rights agreement entered into with PTC, must occur no later than July 19, 2019. The fair value of the Shares is subject to fluctuation in the future due to the volatility of the stock market, changes in general economic conditions, and changes in the financial performance of PTC. We will recognize all changes in the fair value of the Shares (whether realized or unrealized) as gains or losses in our Consolidated Statement of Operations. Accordingly, changes in the fair value of the Shares can materially impact the earnings we report, which introduces volatility in our earnings that is not associated with the results of our business operations. In particular, significant declines in the fair value of the Shares would produce significant declines in our reported earnings.

While there is an established trading market for shares of PTC common stock, there are limitations on our ability to dispose of some or all of the Shares that we own should we wish to reduce our investment. For a period of approximately 3 years, we are subject to contractual restrictions on our ability to transfer the Shares, subject to certain exceptions. In addition, we are subject to certain restrictions on our ability to transfer the Shares under the securities laws. Further, the reported value of our Shares does not necessarily reflect their lowest current market price. If we were forced to sell some or all the Shares in the market, there can be no assurance that we will be able to sell them at prices equivalent to the value of the Shares that we have reported on our Consolidated Balance Sheet, and we may be forced to sell them at significantly lower prices.

Finally, our equity position in PTC is a minority position which exposes us to further risk as we are not able to exert control over PTC.

Non-Cash Investing and Financing Activities

Capital expenditures of $13.4 million and $22.3 million were accrued within accounts payable and other current liabilities at June 30, 2018 and 2017, respectively. At June 30, 2018 and 2017, there were $22.6 million and $3.4 million, respectively, of outstanding common stock share repurchases recorded in accounts payable that did not settle until the next fiscal quarter. These non-cash investing and financing activities have been excluded from cash used for capital expenditures and treasury stock purchases in the Condensed Consolidated Statement of Cash Flows.

Recent Accounting Pronouncements

In March 2017, the FASB issued a new standard regarding the presentation of net periodic pension and postretirement benefit costs. This standard requires the service cost component to be reported in the income statement in the same line item as other compensation costs arising from services rendered by the related employees during the period. The other components of net periodic benefit cost are required to be presented separately from the service cost component in either a separate line item or within another appropriate line item with disclosure of where those costs are recorded. This standard also requires that only the service cost component is eligible for capitalization, when applicable. This standard is effective for us for reporting periods starting October 1, 2018. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued a new standard on accounting for leases that requires lessees to recognize right-of-use assets and lease liabilities for most leases, among other changes to existing lease accounting guidance. The new standard also requires additional qualitative and quantitative disclosures about leasing activities. This standard is effective for us for reporting periods beginning October 1, 2019. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In May 2014, the FASB issued a new standard on revenue recognition related to contracts with customers. This standard supersedes nearly all existing revenue recognition guidance and involves a five-step principles-based approach to recognizing revenue. The underlying principle is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The new standard will also require additional qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract. We will adopt this new standard under the modified retrospective method in the first quarter of fiscal 2019, with the cumulative effect of initially applying the guidance recognized in retained earnings at the adoption date.

We have established a project plan and a cross-functional implementation team to adopt the new revenue standard. We are in the process of identifying and implementing necessary changes to accounting policies, processes, controls and systems to enable compliance with this new standard. We continue to evaluate the impact the adoption of this standard will have on our consolidated financial statements and related disclosures. Although we do not expect the effect of changes to our accounting for revenue and contract costs to be significant, we do expect the impacts will include changes to the timing of revenue currently recognized under the completed contract method, changes to the timing of revenue from software licenses bundled with services, and the capitalization of certain contract costs. We do expect an increase in qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract.

Investments

We record investments in fixed income and equity securities, classified as available-for-sale investments or trading investments, at fair value.

Available-for-sale Investments

We invest in certificates of deposit, time deposits, commercial paper and other fixed income securities which were classified as available-for-sale as of June 30, 2018, and September 30, 2017. Unrealized gains and losses on available-for-sale investments are included in our Condensed Consolidated Balance Sheet as a component of accumulated other comprehensive loss, net of any deferred taxes. Realized gains and losses are included in net income.

Our available-for-sale investments consist of (in millions):

	June 30, 2018		September 30, 2017
Certificates of deposit and time deposits	$	477.9	$	1,005.3
Commercial paper	—		20.3
Corporate debt securities	160.3		199.4
Government securities	65.8		116.8
Asset-backed securities	30.0		45.8
Total	$	734.0	$	1,387.6

Pre-tax gross unrealized gains and losses on available-for-sale investments were not material as of June 30, 2018. Pre-tax gross realized gains and losses on available-for-sale investments were not material for the three and nine months ended June 30, 2018. At June 30, 2018, there were no outstanding purchases of available-for-sale investments recorded in accounts payable.

We evaluated all available-for-sale investments for which the fair value was less than amortized cost for impairment on an individual security basis at June 30, 2018. This assessment included consideration of our intent and ability to hold the security and the credit risks specific to each security. We determined that the declines in fair value of these investments were not other than temporary as of June 30, 2018, and accordingly we did not recognize any impairment charges in net income.

The table below summarizes the contractual maturities of our investments as of June 30, 2018 (in millions). Actual maturities may differ from the contractual maturities below as borrowers may have the right to prepay certain obligations.

	Fair Value
Less than one year	$	548.6
Due in one to five years	185.4
Total	$	734.0

Classification of our available-for-sale investments as current or noncurrent is based on the nature of the investment and when the investment is reasonably expected to be realized. These investments were included in the following line items within the Condensed Consolidated Balance Sheet (in millions):

	June 30, 2018		September 30, 2017
Short-term investments	$	548.6	$	1,124.6

8. Investments (continued)

Trading Investments

On June 11, 2018, we entered into a Securities Purchase Agreement (the "Purchase Agreement") with PTC. PTC agreed to sell 10,582,010 shares of its common stock (the "Shares") to us in a private placement at a purchase price of $94.50 per share for an aggregate purchase price of approximately $1.0 billion. For a period of approximately 3 years after the closing of the Purchase Agreement transaction ("Closing") we are subject to entity-specific transfer restrictions subject to certain exceptions. Following the first anniversary of the Closing, the Company will be allowed to transfer Shares not exceeding, in the aggregate in any 90-day period, a number of Shares equal to up to 1.0% of PTC's total outstanding shares of common stock as of the first day in such 90-day period, but no more than 2.0% of PTC's total outstanding shares of common stock in each of the second year and the third year after the Closing.

The Purchase Agreement, which was a firm commitment as of June 11, 2018, was determined to be a forward contract which was recorded at fair value and designated as a trading security. For the three months ended June 30, 2018, losses of $76.8 million related to this forward contract were recorded in other (expense) income in the Condensed Consolidated Statement of Operations. The forward contract was valued using the difference between the purchase price of $94.50 per share of PTC common stock and the most recent closing price of PTC common stock quoted on Nasdaq, resulting in losses of $7.3 million, less a temporary discount for lack of marketability calculated using a put-option model, resulting in losses of $69.5 million. The discount is due to an instrument-specific restriction as the Shares will be issued as private placements but are contractually required to be registered by PTC under the Securities Act of 1933 within one year, at which time the discount will be reversed. As of June 30, 2018, a corresponding liability is recorded in other current liabilities in the Condensed Consolidated Balance Sheet.

On July 19, 2018, we completed the purchase of the Shares. The investment maintains the same classification as the forward contract, a trading security, and will be recorded at fair value, less a discount for lack of marketability, with any changes in fair value recorded to earnings.

Fair Value of Investments

U.S. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. U.S. GAAP also classifies the inputs used to measure fair value into the following hierarchy:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.

Level 3: Unobservable inputs for the asset or liability.

We recognize all available-for-sale and trading investments at fair value in the Condensed Consolidated Balance Sheet. The valuation methodologies used for our investments measured at fair value are described as follows.

Certificates of deposit and time deposits — These investments are stated at cost, which approximates fair value.

Commercial paper — These investments are stated at amortized cost, which approximates fair value.

Corporate debt securities — Valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flow approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

Government securities — Valued at the most recent closing price on the active market on which the individual securities are traded or, absent an active market, utilizing observable inputs such as closing prices in less frequently traded markets.

Asset-backed securities — Valued using a discounted cash flow approach that maximizes observable inputs, such as current yields of benchmark instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

8. Investments (continued)

Forward contract — Valued using the difference between the PTC purchase price of $94.50 per share of PTC common stock and the most recent closing price of PTC common stock quoted on Nasdaq, less a temporary discount for lack of marketability. The discount for lack of marketability, which will reverse upon registration of the PTC securities, is calculated using a put-option model which includes observable and unobservable inputs and is categorized as Level 3 in the fair value hierarchy. The primary inputs include historical and implied PTC common stock volatility and the restriction term.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. We did not have any transfers between levels of fair value measurements during the periods presented.

Unrealized gains	19.3
Balance June 30, 2018	$	(76.8	)

The loss of $96.1 million upon the agreement commencement date includes a loss of $28.1 million, resulting from the difference between the purchase price of $94.50 per share of PTC common stock and the June 11, 2018 closing price of PTC common stock, and a $68.0 million valuation adjustment pending registration of the PTC securities. The unrealized gain of $19.3 million includes a gain of $20.8 million, resulting from the appreciation of PTC common stock between the agreement commencement date and the end of the quarter, partially offset by a $1.5 million increase in the valuation adjustment associated with the appreciation of PTC’s common stock. The unrealized loss of $76.8 million at June 30, 2018 includes a $7.3 million loss on investment and a $69.5 million valuation adjustment.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

Various lawsuits, claims and proceedings have been or may be instituted or asserted against us relating to the conduct of our business, including those pertaining to product liability, environmental, safety and health, intellectual property, employment and contract matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, we believe the disposition of matters that are pending or have been asserted will not have a material effect on our business, financial condition or results of operations.

We (including our subsidiaries) have been named as a defendant in lawsuits alleging personal injury as a result of exposure to asbestos that was used in certain components of our products many years ago. Currently there are a few thousand claimants in lawsuits that name us as defendants, together with hundreds of other companies. In some cases, the claims involve products from divested businesses, and we are indemnified for most of the costs. However, we have agreed to defend and indemnify asbestos claims associated with products manufactured or sold by our former Dodge mechanical and Reliance Electric motors and motor repair services businesses prior to their divestiture by us, which occurred on January 31, 2007. We are also responsible for half of the costs and liabilities associated with asbestos cases against the former Rockwell International Corporation’s divested measurement and flow control business. But in all cases, for those claimants who do show that they worked with our products or products of divested businesses for which we are responsible, we nevertheless believe we have meritorious defenses, in substantial part due to the integrity of the products, the encapsulated nature of any asbestos-containing components, and the lack of any impairing medical condition on the part of many claimants. We defend those cases vigorously. Historically, we have been dismissed from the vast majority of these claims with no payment to claimants.

We have maintained insurance coverage that we believe covers indemnity and defense costs, over and above self-insured retentions, for claims arising from our former Allen-Bradley subsidiary. Our insurance carrier entered into a cost share agreement with us to pay the substantial majority of future defense and indemnity costs for Allen-Bradley asbestos claims. We believe that this arrangement will continue to provide coverage for Allen-Bradley asbestos claims throughout the remaining life of the asbestos liability.

We also have rights to historic insurance policies that provide indemnity and defense costs, over and above self-insured retentions, for claims arising out of certain asbestos liabilities relating to the divested measurement and flow control business. We initiated litigation against several insurers to pursue coverage for these claims, subject to each carrier's policy limits, and the case is now pending in Los Angeles County Superior Court. In September 2016, we entered into settlement agreements with certain insurance company defendants, and we continue to pursue our claims against the remaining defendants. We believe these settlement agreements will continue to provide partial coverage for these asbestos claims throughout the remaining life of asbestos liability.

The uncertainties of asbestos claim litigation make it difficult to predict accurately the ultimate outcome of asbestos claims. That uncertainty is increased by the possibility of adverse rulings or new legislation affecting asbestos claim litigation or the settlement process. Subject to these uncertainties and based on our experience defending asbestos claims, we do not believe these lawsuits will have a material effect on our business, financial condition or results of operations.

We have, from time to time, divested certain of our businesses. In connection with these divestitures, certain lawsuits, claims and proceedings may be instituted or asserted against us related to the period that we owned the businesses, either because we agreed to retain certain liabilities related to these periods or because such liabilities fall upon us by operation of law. In some instances, the divested business has assumed the liabilities; however, it is possible that we might be responsible for satisfying those liabilities if the divested business is unable to do so.

In connection with the spin-offs of our former automotive business, semiconductor systems business and avionics and communications business, the spun-off companies have agreed to indemnify us for substantially all contingent liabilities related to the respective businesses, including environmental and intellectual property matters.

In conjunction with the sale of our Dodge mechanical and Reliance Electric motors and motor repair services businesses, we agreed to indemnify Baldor Electric Company for costs and damages related to certain legal, legacy environmental and asbestos matters of these businesses arising before January 31, 2007, for which the maximum exposure would be capped at the amount received for the sale.

11. Commitments and Contingent Liabilities (continued)

In many countries we provide a limited intellectual property indemnity as part of our terms and conditions of sale. We also at times provide limited intellectual property indemnities in other contracts with third parties, such as contracts concerning the development and manufacture of our products. As of June 30, 2018, we were not aware of any material indemnification claims where an unfavorable outcome was probable or reasonably possible. Historically, claims that have been made under the indemnification agreements have not had a material impact on our business, financial condition or results of operations; however, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our business, financial condition or results of operations in a particular period.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

At the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur.

Our base rate reflects a change in the U.S. federal statutory rate from 35 percent to 21 percent resulting from the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) on December 22, 2017. The rate change was effective for us at the beginning of our fiscal year, using a blended rate for the annual period. As a result, the blended statutory tax rate for our fiscal year 2018 is 24.53 percent.

The effective tax rate was 21.1 percent and 77.7 percent in the three and nine months ended June 30, 2018, respectively, compared to 21.4 percent and 18.7 percent in the three and nine months ended June 30, 2017, respectively. The effective tax rate was lower than the U.S. statutory rate of 24.53 percent in the three months ended June 30, 2018, primarily because we benefited from lower non-U.S. tax rates and also realized a benefit from discrete tax items, partially offset by the PTC investment adjustments without a corresponding tax benefit. The effective tax rate was higher than the U.S. statutory rate of 24.53 percent in the nine months ended June 30, 2018, due to provisional tax expense ($483.7 million or 57.0 percent) resulting from the Tax Act. The effective tax rate was lower than the U.S. statutory rate of 35 percent in the three and nine months ended June 30, 2017, primarily because we benefited from lower non-U.S. tax rates, and we also realized a benefit from discrete tax items.

Provisional Amounts

The Tax Act requires us to revalue our existing U.S. deferred tax balance to reflect the lower statutory tax rate and pay a one-time tax on earnings of certain foreign subsidiaries that were previously deferred from U.S. tax (“transition tax”). At June 30, 2018, we have not completed our accounting for the tax effects of the Tax Act; however, we have made reasonable estimates of its effects on our existing U.S. deferred tax balance and the transition tax and recorded provisional amounts which are included as a component of income tax expense from continuing operations, as discussed in more detail below.

We revalued our U.S. deferred tax assets and liabilities based on the rate at which they are expected to reverse in the future, which is either 24.53 percent for reversals in 2018 or 21 percent for reversals in 2019 and subsequent years. However, we are still analyzing certain aspects of the Tax Act and refining our calculations, which could potentially affect the valuation of these balances or potentially give rise to new deferred tax amounts. We have recorded a provisional amount of $94.2 million in the nine months ended June 30, 2018, of which the entire amount was recorded in the three months ended December 31, 2017.

The Tax Act requires the transition tax to be computed based on our total post-1986 earnings and profits (“E&P”) at December 31, 2017, that were previously deferred from U.S. income tax. As a result, we are required to make reasonable estimates given our September 30 fiscal year. We have recorded a provisional benefit of $7.5 million and provisional expense of $389.5 million for the transition tax liability for all of our foreign subsidiaries in the three and nine months ended June 30, 2018, respectively. At June 30, 2018, we have recorded income taxes payable of $389.5 million related to the transition tax in the Condensed Consolidated Balance Sheet, of which $34.1 million is recorded within other current liabilities, and $355.4 million is recorded within other liabilities because that portion is payable greater than twelve months after June 30, 2018.

12. Income Taxes (continued)

The transition tax is applied to the balance of post-1986 E&P at rates of 15.5 percent for cash assets (as defined in the Tax Act) and 8 percent for non-cash assets measured at the higher of the balance at September 30, 2018, or the average of the ending balances at September 30, 2016, and September 30, 2017. Our reasonable estimates will change as a result of adjustments impacting E&P, and distributions and other transactions impacting cash. The Company anticipates that it will complete its accounting for the transition tax at December 31, 2018. These uncertainties form the basis for the Company’s provisional reporting based upon reasonable estimates at June 30, 2018.

The Company has historically accounted for the earnings of its foreign subsidiaries as being indefinitely reinvested under ASC 740-30. As a result of the broad changes to the U.S. international tax system under the Tax Act, the Company will begin to account for substantially all of its non-U.S. subsidiaries as being immediately subject to tax other than in certain limited circumstances. The Company has provided for taxes on the balance of historic and current earnings that may be subject to foreign withholding and U.S. state taxes. For future distributions related to historic earnings, we recorded deferred tax liabilities of $59.8 million related to foreign withholding taxes, and deferred tax assets of $59.8 million related to foreign tax credits attributable to the foreign withholding taxes. These provisional amounts are presented net within deferred income tax assets in the Condensed Consolidated Balance Sheet as of June 30, 2018.  We have not yet completed our assessment of whether a portion of these assets and liabilities should be presented as gross amounts.

Unrecognized Tax Benefits

The amount of gross unrecognized tax benefits was $19.4 million and $31.1 million at June 30, 2018, and September 30, 2017, respectively, of which the entire amount would reduce our effective tax rate if recognized.

Accrued interest and penalties related to unrecognized tax benefits were $3.7 million and $4.0 million at June 30, 2018, and September 30, 2017, respectively. We recognize interest and penalties related to unrecognized tax benefits in the income tax provision.

We believe it is reasonably possible that the amount of gross unrecognized tax benefits could be reduced by up to $5.1 million in the next 12 months as a result of the resolution of tax matters in various global jurisdictions and the lapses of statutes of limitations. If all of the unrecognized tax benefits were recognized, the net reduction to our income tax provision, including the recognition of interest and penalties and offsetting tax assets, could be up to $4.5 million.

We conduct business globally and are routinely audited by the various tax jurisdictions in which we operate. We are no longer subject to U.S. federal income tax examinations for years before 2016 and are no longer subject to state, local and foreign income tax examinations for years before 2003.

Among other considerations, we evaluate performance and allocate resources based upon segment operating earnings before income taxes, costs related to the unsolicited Emerson proposals in the first quarter of fiscal 2018, interest expense, costs related to corporate offices, non-operating pension costs, certain corporate initiatives, gains and losses on investments, valuation adjustment pending registration of PTC securities, gains and losses from the disposition of businesses, and purchase accounting depreciation and amortization. We incurred $11.2 million of third-party advisory fees in connection with our evaluation of unsolicited Emerson acquisition proposals in the first quarter of 2018. Depending on the product, intersegment sales within a single legal entity are either at cost or cost plus a mark-up, which does not necessarily represent a market price. Sales between legal entities are at an appropriate transfer price. We allocate costs related to shared segment operating activities to the segments using a methodology consistent with the expected benefit.

Recent accounting pronouncements

Recent Accounting Pronouncements

In March 2017, the FASB issued a new standard regarding the presentation of net periodic pension and postretirement benefit costs. This standard requires the service cost component to be reported in the income statement in the same line item as other compensation costs arising from services rendered by the related employees during the period. The other components of net periodic benefit cost are required to be presented separately from the service cost component in either a separate line item or within another appropriate line item with disclosure of where those costs are recorded. This standard also requires that only the service cost component is eligible for capitalization, when applicable. This standard is effective for us for reporting periods starting October 1, 2018. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued a new standard on accounting for leases that requires lessees to recognize right-of-use assets and lease liabilities for most leases, among other changes to existing lease accounting guidance. The new standard also requires additional qualitative and quantitative disclosures about leasing activities. This standard is effective for us for reporting periods beginning October 1, 2019. We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements and related disclosures.

In May 2014, the FASB issued a new standard on revenue recognition related to contracts with customers. This standard supersedes nearly all existing revenue recognition guidance and involves a five-step principles-based approach to recognizing revenue. The underlying principle is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The new standard will also require additional qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract. We will adopt this new standard under the modified retrospective method in the first quarter of fiscal 2019, with the cumulative effect of initially applying the guidance recognized in retained earnings at the adoption date.

We have established a project plan and a cross-functional implementation team to adopt the new revenue standard. We are in the process of identifying and implementing necessary changes to accounting policies, processes, controls and systems to enable compliance with this new standard. We continue to evaluate the impact the adoption of this standard will have on our consolidated financial statements and related disclosures. Although we do not expect the effect of changes to our accounting for revenue and contract costs to be significant, we do expect the impacts will include changes to the timing of revenue currently recognized under the completed contract method, changes to the timing of revenue from software licenses bundled with services, and the capitalization of certain contract costs. We do expect an increase in qualitative and quantitative disclosures about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized from the costs to obtain or fulfill a contract.

Product warranty obligations

We record a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. Most of our products are covered under a warranty period that runs for twelve months from either the date of sale or installation. We also record a liability for specific warranty matters when they become probable and reasonably estimable.

Investments

We invest in certificates of deposit, time deposits, commercial paper and other fixed income securities which were classified as available-for-sale as of June 30, 2018, and September 30, 2017. Unrealized gains and losses on available-for-sale investments are included in our Condensed Consolidated Balance Sheet as a component of accumulated other comprehensive loss, net of any deferred taxes. Realized gains and losses are included in net income.

Fair Value of Financial Instruments

Fair Value of Investments

U.S. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. U.S. GAAP also classifies the inputs used to measure fair value into the following hierarchy:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.

Level 3: Unobservable inputs for the asset or liability.

We recognize all available-for-sale and trading investments at fair value in the Condensed Consolidated Balance Sheet. The valuation methodologies used for our investments measured at fair value are described as follows.

Certificates of deposit and time deposits — These investments are stated at cost, which approximates fair value.

Commercial paper — These investments are stated at amortized cost, which approximates fair value.

Corporate debt securities — Valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flow approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

Government securities — Valued at the most recent closing price on the active market on which the individual securities are traded or, absent an active market, utilizing observable inputs such as closing prices in less frequently traded markets.

Asset-backed securities — Valued using a discounted cash flow approach that maximizes observable inputs, such as current yields of benchmark instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

8. Investments (continued)

Forward contract — Valued using the difference between the PTC purchase price of $94.50 per share of PTC common stock and the most recent closing price of PTC common stock quoted on Nasdaq, less a temporary discount for lack of marketability. The discount for lack of marketability, which will reverse upon registration of the PTC securities, is calculated using a put-option model which includes observable and unobservable inputs and is categorized as Level 3 in the fair value hierarchy. The primary inputs include historical and implied PTC common stock volatility and the restriction term.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. We did not have any transfers between levels of fair value measurements during the periods presented.

Income taxes

At the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur.
