Basis of Presentation	'
	1	Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the Securities and Exchange Commission (“SEC”) requirements for interim reporting, which allows certain footnotes and other financial information normally required by accounting principles generally accepted in the United States of America to be condensed or omitted. In our opinion, the Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of our financial position and results of operations.
	These statements should be read in conjunction with the Consolidated Financial Statements and Notes included in our annual report on Form 10-K for the year ended December 31, 2013. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

	Presentation of Unrecognized Tax Benefits
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued amendments to guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. The amendments require entities to present an unrecognized tax benefit netted against certain deferred tax assets when specific requirements are met. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013; however, early adoption is permitted. Adoption of this guidance did not have a material impact on our results of operations or financial position.

	Q4 2013 Action - During the fourth quarter of 2013, we implemented a restructuring action to right size the cost structure in our European operations, primarily as a result of the strategic decision to adjust our Direct versus Distribution selling efforts, to enhance our go-to-market approach which is anticipated to improve profitability and increase customer satisfaction. The pre-tax charge of $1,577 recognized in the fourth quarter consisted primarily of severance and was included within Selling and Administrative Expense in the Condensed Consolidated Statements of Earnings. We do not expect additional costs will be incurred related to this restructuring action and we believe the anticipated savings will offset the pre-tax charge in approximately 1.5 years. The charge impacted our Europe, Middle East, Africa (EMEA) operating segment, which has no goodwill balance.
	A reconciliation of the beginning and ending liability balances is as follows:
			Severance and Related Costs
	Q4 2013 restructuring action		$	1,577

	Q1 2013 Action - During the first quarter of 2013, we implemented a restructuring action to right size the cost structure of our European operations, primarily focused on reducing the size of our sales and service organization, in response to the challenging economic situation. The pre-tax charge of $1,440 recognized in the first quarter consisted primarily of severance and was included within Selling and Administrative Expense in the Condensed Consolidated Statements of Earnings. We do not expect additional costs will be incurred related to this restructuring action and the anticipated savings will offset the pre-tax charge in approximately one year. The charge impacted our Europe, Middle East, Africa (EMEA) operating segment, which has no goodwill balance.
	A reconciliation of the beginning and ending liability balances is as follows:

	Acquisitions
	On May 31, 2011, we acquired Water Star, Inc. (“Water Star”), a Newbury, Ohio firm specializing in electrochemistry for $4,456. The total purchase price of $4,456 was comprised of $2,956 paid at closing and two $750 installment payments which were paid in cash on May 31, 2012 and 2013. This acquisition is consistent with our strategy to expand our intellectual property in support of our long-term vision to deliver sustainable, breakthrough innovations.
	Divestitures
	On July 31, 2012, we entered into a Share Purchase Agreement (“SPA”) with M&F Management and Financing GmbH (“M&F”) for the sale of ownership of our subsidiary, Tennant CEE GmbH, and our minority interest in a joint venture, OOO Tennant. In exchange for the ownership of these entities, we received €815, or $1,014 as of the date of sale, in cash and financed the remaining €5,351, for a total purchase price of €6,166. A total of €2,126, or $2,826, was received in equal quarterly payments during 2013 and the first anniversary payment of €1,075, or $1,435, was received on July 31, 2013. The remaining €2,150, or $2,943, as of June 30, 2014, will be received in equal installments on the second and third anniversary dates of the divestiture. As a result of this divestiture, we recorded a pre-tax gain of $784 during the third quarter of 2012 in our Profit from Operations in the Condensed Consolidated Statements of Earnings.
	M&F is now a master distributor of Tennant products in the Central Eastern Europe, Middle East and Africa markets. In addition, as further discussed in Note 17, at the time of the transaction, M&F was a related party of ours. We have identified M&F as a variable interest entity (“VIE”) and have performed a qualitative assessment that considered M&F's purpose and design, our involvement and the risks and benefits and determined that we are not the primary beneficiary of this VIE. The only financing we have provided to M&F was related to the SPA as noted above and there are no arrangements that would require us to provide significant financial support in the future.

	Estimates of fair value for financial assets and financial liabilities are based on the framework established in the accounting guidance for fair value measurements. The framework defines fair value, provides guidance for measuring fair value and requires certain disclosures. The framework discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The framework utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
	•	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
	•	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
	•	Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.
	Our population of assets and liabilities subject to fair value measurements at June 30, 2014 is as follows:
		Fair		Level 1		Level 2		Level 3
		Value
	Assets:
	Foreign currency forward exchange contracts	$	18	$	—	$	18	$	—
	Total Assets	$	18	$	—	$	18	$	—
	Liabilities:
	Foreign currency forward exchange contracts	$	138	$	—	$	138	$	—
	Total Liabilities	$	138	$	—	$	138	$	—
	Our foreign currency forward exchange contracts are valued based on quoted forward foreign exchange prices at the reporting date.
	We use derivative instruments to manage exposures to foreign currency only in an attempt to limit underlying exposures from currency fluctuations and not for trading purposes. Gains or losses on forward foreign exchange contracts that hedge foreign currency-denominated assets and liabilities are recognized in Other Current Assets and Other Current Liabilities within the Condensed Consolidated Balance Sheets and are recognized in Other Income (Expense), Net under Net Foreign Currency Transaction Gains (Losses) within the Condensed Consolidated Statements of Earnings. As of June 30, 2014, the fair value of such contracts outstanding was an asset of $18 and a liability of $138. As of December 31, 2013, the fair value of such contracts outstanding was an asset of $16 and a liability of $109. At June 30, 2014 and December 31, 2013, the notional amounts of foreign currency forward exchange contracts outstanding were $39,068 and $30,280, respectively. We recognized a net loss of $902 and a net gain of $901 on such contracts during the first six months of 2014 and 2013, respectively.
	The carrying amounts reported in the Condensed Consolidated Balance Sheets for Cash and Cash Equivalents, Accounts Receivable, Other Current Assets, Accounts Payable and Other Current Liabilities approximate fair value.
	The fair value of our Long-Term Debt approximates cost based on the borrowing rates currently available to us for bank loans with similar terms and remaining maturities.

	Certain operating leases for vehicles contain residual value guarantee provisions, which would become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. As of June 30, 2014, of those leases that contain residual value guarantees, the aggregate residual value at lease expiration was $12,055, of which we have guaranteed $9,799. As of June 30, 2014, we have recorded a liability for the estimated end of term loss related to this residual value guarantee of $194 for certain vehicles within our fleet. Our fleet also contains vehicles we estimate will settle at a gain. Gains on these vehicles will be recognized at the end of the lease term.
	During the second quarter of 2014, we entered into a three year software licensing agreement with a total commitment of $1,198.
	During the second quarter of 2012, we entered into a three year agreement with a supplier, commencing January 1, 2013, with a total commitment of $2,102 of which $1,054 is still outstanding as of June 30, 2014.

	We and our subsidiaries are subject to U.S. federal income tax as well as income tax of numerous state and foreign jurisdictions. We are generally no longer subject to U.S. federal tax examinations for taxable years before 2011 and, with limited exceptions, state and foreign income tax examinations for taxable years before 2007.
	We recognize potential accrued interest and penalties related to unrecognized tax benefits in Income Tax Expense. In addition to the liability of $3,931 for unrecognized tax benefits as of June 30, 2014, there was approximately $617 for accrued interest and penalties. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of June 30, 2014 was $3,623. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be revised and reflected as an adjustment of the Income Tax Expense.
	Unrecognized tax benefits were reduced by $21 during the first six months of 2014 for expiration of the statute of limitations in various jurisdictions.
	We are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2007 to 2011 for which settlement is expected prior to year end. Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.

	We are organized into four operating segments: North America; Latin America; Europe, Middle East and Africa; and Asia Pacific. We combine our North America and Latin America operating segments into the “Americas” for reporting Net Sales by geographic area. In accordance with the objective and basic principles of the applicable accounting guidance, we aggregate our operating segments into one reportable segment that consists of the design, manufacture and sale of products used primarily in the maintenance of nonresidential surfaces.
