CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Consolidated Financial Information

The unaudited consolidated financial information for the second quarter and six months ended June 30, 2013 and 2012 reflect, in the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations, comprehensive income and cash flows of Ecolab Inc. (“Ecolab” or “the company”) for the interim periods presented. The financial results for any interim period are not necessarily indicative of results for the full year. The consolidated balance sheet data as of December 31, 2012 was derived from the audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited consolidated financial information should be read in conjunction with the consolidated financial statements and notes thereto incorporated in the company’s Annual Report on Form 10-K for the year ended December 31, 2012.

With respect to the unaudited financial information of the company for the second quarter and six months ended June 30, 2013 and 2012 included in this Form 10-Q, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated August 1, 2013 appearing herein states that they did not audit and they do not express an opinion on that unaudited financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended (the “Act”), for their report on the unaudited financial information because that report is not a “report” or a “part” of a registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Act.

2.       Special (Gains) and Charges

Special (gains) and charges reported on the Consolidated Statement of Income include the following:

For segment reporting purposes, special (gains) and charges are included in the Corporate segment, which is consistent with the company’s internal management reporting.

Restructuring Charges

The company incurs costs for restructuring activities associated with plans to enhance its efficiency and effectiveness and sharpen its competitiveness. These restructuring plans include costs associated with significant actions involving employee-related severance charges, contract termination costs and asset write-downs. Employee termination costs are largely based on policies and severance plans, and include personnel reductions and related costs for severance, benefits and outplacement services. These charges are reflected in the quarter when the actions are probable and the amounts are estimable, which typically is when management approves the associated actions. Contract termination costs include charges to terminate leases prior to the end of their respective terms and other contract terminations. Asset write-downs include leasehold improvement write-downs and other asset write-downs associated with combining operations.

2.  Special (Gains) and Charges (continued)

Restructuring charges have been included as a component of both cost of sales and special (gains) and charges on the Consolidated Statement of Income. Amounts included as a component of cost of sales include supply chain related severance and other asset write-downs associated with combining operations. Restructuring liabilities have been classified as a component of other current liabilities on the Consolidated Balance Sheet.

Energy Restructuring Plan

On April 10, 2013, the company completed its acquisition of privately held Champion Technologies and its related company Corsicana Technologies (collectively “Champion”).

In April 2013, following the completion of the acquisition of Champion, the company commenced plans to undertake restructuring and other cost-saving actions to realize its acquisition-related cost synergies as well as streamline and strengthen Ecolab’s position in the fast growing energy market (the “Energy Restructuring Plan”). Actions associated with the acquisition to improve the effectiveness and efficiency of the business include a reduction of the combined business’s current global workforce by approximately 500 positions. A number of these reductions are expected to be achieved through eliminating open positions and attrition. The company also anticipates leveraging and simplifying its global supply chain, including the reduction of plant and distribution center locations and product line optimization, as well as the reduction of other redundant facilities.

The company expects to incur pretax restructuring charges of approximately $80 million ($55 million after tax) under the Energy Restructuring Plan through the completion of the Plan in 2015. Approximately $40 million to $50 million ($25 million to $30 million after tax) of those charges are expected to occur in 2013.

The company anticipates that approximately $60 million of the $80 million of the pre-tax charges represent cash expenditures. The remaining pre-tax charges represent estimated asset disposals. No decisions have been made for any asset disposals and estimates could vary depending on the actual actions taken.

As a result of restructuring activities under the Energy Restructuring Plan, the company recorded restructuring charges of $12.2 million ($7.6 million after tax) during both the second quarter and six months ended June 30, 2013.

Restructuring charges and activity related to the Energy Restructuring Plan since inception of the underlying actions include the following:

Cash payments under the Energy Restructuring Plan during 2013 were $10 million. The majority of cash payments under this Plan are related to severance, with the current accrual expected to be paid over the next twelve months.

Combined Restructuring Plan

In February 2011, the company commenced a comprehensive plan to substantially improve the efficiency and effectiveness of its European business, sharpen its competitiveness and accelerate its growth and profitability. Additionally, restructuring has been and will continue to be undertaken outside of Europe (collectively, the “2011 Restructuring Plan”). Total anticipated charges under this Plan from 2011 through 2013 were expected to be $150 million ($125 million after tax). Through 2012, $134 million of charges ($100 million after tax) were incurred.

In January 2012, following the merger with Nalco Holding Company (“Nalco”), the company formally commenced plans to undertake restructuring actions related to the reduction of its global workforce and optimization of its supply chain and office facilities, including planned reductions of plant and distribution center locations (the “Merger Restructuring Plan”). Total anticipated charges from 2012 through 2013 were expected to be $180 million ($120 million after tax) under this Plan. Through 2012, $80 million of charges ($59 million after tax) were incurred.

During the first quarter of 2013, as the company considered opportunities to enhance the efficiency and effectiveness of its operations, it decided that because the objectives of the plans discussed above were aligned, the previously separate restructuring plans should be combined into one plan.

The combined restructuring plan (the “Combined Plan”) combined opportunities and initiatives from both plans and is expected to be substantially completed by the end of 2013. The Combined Plan will continue to follow the original format of the Merger Restructuring Plan by focusing on global actions related to optimization of the supply chain and office facilities, including reductions of plant and distribution center locations and the global workforce. Through the completion of the Combined Plan, the company expects to incur total pretax restructuring charges of approximately $80 million to $100 million ($55 million to $70 million after tax), of which approximately $25 million to $45 million ($20 million to $30 million after tax) remained to be incurred as of June 30, 2013.

The company anticipates that approximately $70 million to $80 million of the total Combined Plan pre-tax charges will represent net cash expenditures. The remaining pre-tax charges represent estimated asset disposals. No decisions have been made for any remaining asset disposals and estimates could vary depending on the actual actions taken.

As a result of restructuring activities under the Combined Plan, the company recorded restructuring charges of $34.4 million ($26.1 million after tax) and $55.2 million ($40.4 million after tax), during the second quarter and six months ended June 30, 2013, respectively.

Restructuring charges and activity related to Combined Plan since inception of the underlying actions include the following:

Cash payments under the Combined Plan were $62 million, $65 million and $25 million for the first six months of 2013, full year 2012 and full year 2011, respectively. The majority of cash payments under this Plan are related to severance, with the current accrual expected to be paid over a period of a few months to a period of several quarters.

Nalco Restructuring Plan

Prior to the Nalco merger, Nalco conducted various restructuring programs to redesign and optimize its business and work processes (the “Nalco Restructuring Plan”). As of June 30, 2013 and December 31, 2012, the remaining liability balance related to the Nalco Restructuring Plan was $2.4 million and $3.4 million, respectively. Cash payments during the six months of 2013 related to this Plan were $0.7 million. The company expects to substantially utilize the remaining liability by the end of 2014.

Non-restructuring Special (Gains) and Charges

Champion acquisition & integration costs

As a result of the company’s efforts to acquire Champion and post acquisition integration costs, the company incurred charges of $37.9 million ($27.6 million after tax) and $47.9 million ($34.7 million) during the second quarter and six months ended June 30, 2013, respectively.

Champion acquisition related costs have been included as a component of cost of sales, special (gains) and charges and net interest expense on the Consolidated Statement of Income. Amounts within cost of sales include the recognition of fair value step-up in Champion international inventory, which is maintained on a FIFO basis. Amounts included in special (gains) and charges include acquisition costs, advisory fees and integration charges. Amounts included in net interest expense include the interest expense through the close date of the Champion transaction of the company’s $500 million public debt issuance in December 2012 as well as fees to secure term loans and short-term debt, all of which were initiated to fund the Champion acquisition. Further information related to the acquisition of Champion is included in Note 3.

Nalco merger & integration costs

As a result of the Nalco merger completed in 2011, the company incurred charges of $4.4 million ($3.0 million after tax) and $13.0 million ($8.8 million after tax) during the second quarter of 2013 and 2012, respectively. During the six months ended June 30, 2013 and 2012, the company incurred charges of $8.2 million ($5.7 million after tax) and $115.5 million ($86.5 million after tax), respectively.

Nalco related special charges for 2013 have been included as a component of special (gains) and charges on the Consolidated Statement of Income, and include integration charges. Nalco related special charges for 2012 have been included as a component of cost of sales, special (gains) and charges, net interest expense and net income (loss) attributable to noncontrolling interest on the Consolidated Statement of Income. Amounts within cost of sales and net income (loss) attributable to noncontrolling interest include the recognition of fair value step-up in Nalco international inventory, which is maintained on a FIFO basis. Amounts within special (gains) and charges include merger and integration charges. Amounts within net interest expense for 2012 include a loss on the extinguishment of Nalco’s senior notes, which were assumed as part of the merger.

Venezuelan currency devaluation

On February 8, 2013, the Venezuelan government devalued its currency, the Bolivar Fuerte. As a result of the devaluation, during the first quarter of 2013, the company recorded a charge of $22.9 million ($15.0 million after tax), reflected as a component of special (gains) and charges, due to the remeasurement of the local balance sheet. Due to the ownership structure in place in Venezuela, the company also reflected a portion of the impact of the devaluation as a component of net income (loss) attributable to noncontrolling interest on the Consolidated Statement of Income.

3.       Acquisitions and Dispositions

Champion acquisition

In October 2012, the company entered into an agreement and plan of merger to acquire Champion. Based in Houston, Texas, Champion is a global energy specialty products and services company delivering its offerings to the oil and gas industry.

In November 2012, the company amended the acquisition agreement to provide that Champion’s downstream business would not be acquired by the company. Further, in April 2013, the company entered into a consent agreement with the U.S. Department of Justice under which Ecolab took certain steps designed to ensure continued independent competition utilizing Champion technology for certain U.S. deepwater Gulf of Mexico products and services. The amendment and consent agreement discussed above do not significantly impact the value of the acquisition transaction. On April 10, 2013, the company completed its acquisition of Champion. Champion’s sales for the business acquired by the company were approximately $1.3 billion in 2012. The business became part of the company’s Global Energy reportable segment in the second quarter of 2013.

Pursuant to the terms of the acquisition agreement, the consideration transferred at closing to acquire all of Champion’s stock is as follows:

The company deposited approximately $100 million of the above stock consideration in an escrow account to fund post-closing adjustments to the consideration and covenant and other indemnification obligations of the acquired entity’s stockholders for a period of two years following the effective date of the acquisition. As of the end of the second quarter of 2013, the consideration transferred at closing is subject to working capital and other adjustments in accordance with the acquisition agreement.

The company incurred certain acquisition and integration costs associated with the transaction that were expensed as incurred and are reflected in the Consolidated Statement of Income. During the first six months of 2013, a total of $47.9 million was incurred with $13.6 million included in cost of sales related to recognition of fair value step-up in Champion international inventory, which is maintained on a FIFO basis, $31.8 million included in special (gains) and charges related to acquisition costs, advisory fees and integration costs and $2.5 million included in net interest expense related to interest expense through the close date of the Champion transaction of the company’s $500 million public debt issuance in December 2012 as well as fees to secure term loans and short-term debt.

The company funded the initial cash component of the merger consideration through a $900 million unsecured term loan, initiated in April 2013, the proceeds from the December 2012 issuance of $500 million of 1.450% senior notes due 2017 and commercial paper borrowings backed by its syndicated credit facility. See Note 5 for further discussion on the company’s debt.

3.       Acquisitions and Dispositions (continued)

The Champion acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that most assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. Certain estimated values are not yet finalized and are subject to change, which could be significant.

The company will finalize the amounts recognized as information necessary to complete the analysis is obtained. The company expects to finalize these by the filing of the 2013 Form 10-k. Amounts for certain contingent liabilities, certain tangible and intangible assets, certain deferred tax assets and liabilities, income tax uncertainties, non-wholly owned subsidiaries and goodwill remain subject to change.

The following table summarizes the preliminary value of Champion assets acquired and liabilities assumed as of the acquisition date.
