TENNANT COMPANY

2013

ANNUAL REPORT

Form 10–K

(Pursuant to Securities Exchange Act of 1934)

PART I

ITEM 1 – Business

General Development of Business

Tennant Company, a Minnesota corporation that was founded in 1870 and incorporated in 1909, is a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world. The Company’s floor maintenance and outdoor cleaning equipment, chemical-free and other sustainable cleaning technologies, coatings and related products are used to clean and coat surfaces in factories, transportation facilities, public venues, warehouses, retail, education, healthcare, office buildings, parking lots and streets, and other environments. Customers include building service contract cleaners to whom organizations outsource facilities maintenance, as well as end-user businesses, healthcare facilities, schools and local, state and federal governments that handle facilities maintenance themselves. The Company reaches these customers through the industry’s largest direct sales and service organization and through a strong and well-supported network of authorized distributors worldwide.

Segment and Geographic Area Financial Information

The Company has one reportable business segment. Sales to customers geographically located in the United States were $422.6 million, $406.2 million and $392.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. Long-lived assets located in the United States were $82.7 million and $74.0 million as of the years ended December 31, 2013 and 2012, respectively. Additional financial information on the Company’s segment and geographic areas is provided throughout Item 8 and Note 17 of the Consolidated Financial Statements.

Principal Products, Markets and Distribution

The Company offers products and solutions mainly consisting of mechanized cleaning equipment targeted at manufacturing, warehouse and logistics, transportation facilities, public venues, retail, healthcare and education markets; parts, consumables and service maintenance and repair; business solutions such as rental and leasing programs; and sustainable cleaning technologies that reduce the need for chemicals in the cleaning process. Adjacent products include surface coatings and floor preservation products. The Company’s suite of offerings are marketed and sold under the following brands: Tennant®, Nobles®, Green Machines™, Alfa Uma Empresa Tennant™ and Orbio®. The Orbio brand of products and solutions is developed and managed by Orbio Technologies, a group created by Tennant to focus on expanding the opportunities for water-based sustainable technologies such as ec-H2O™ and Orbio 5000-Sc. Tennant Company’s products are sold through direct and distribution channels in various regions around the world. In North America, Brazil, Australia, China and most of Western Europe, products are sold through a direct sales organization and independent distributors. In more than 80 other countries, the Company relies on a broad network of independent distributors.

Raw Materials

The Company has not experienced any significant or unusual problems in the availability of raw materials or other product components. The Company has sole-source vendors for certain components. A disruption in supply from such vendors may disrupt the Company’s operations. However, the Company believes that it can find alternate sources in the event there is a disruption in supply from such vendors.

Intellectual Property

Although the Company considers that its patents, proprietary technologies, customer relationships, licenses, trademarks, trade names and brand names in the aggregate constitute a valuable asset, it does not regard its business as being materially dependent upon any single intellectual property.

Seasonality

Although the Company’s business is not seasonal in the traditional sense, the percentage of revenues in each quarter typically ranges from 22% to 28% of the total year. The first quarter tends to be at the low end of the range reflecting customers’ initial slow ramp up of capital purchases and the Company’s efforts to close out orders at the end of each year. The second and fourth quarters tend to be towards the high end of the range and the third quarter is typically in the middle of the range.

Working Capital

The Company funds operations through a combination of cash and cash equivalents and cash flows from operations. Wherever possible, cash management is centralized and intercompany financing is used to provide working capital to subsidiaries as needed. In addition, credit facilities are available for additional working capital needs or investment opportunities.

Major Customers

The Company sells its products to a wide variety of customers, none of which is of material importance in relation to the business as a whole. The customer base includes several governmental entities which generally have terms similar to other customers.

Backlog

The Company processes orders within two weeks on average. Therefore, no significant backlogs existed at December 31, 2013 and 2012.

3

Competition

While there is no publicly available industry data concerning market share, the Company believes, through its own market research, that it is a world-leading manufacturer of floor maintenance and cleaning equipment. Significant competitors exist in all key geographic regions. However, the key competitors vary by region. The Company competes primarily on the basis of offering a broad line of high-quality, innovative products supported by an extensive sales and service network in major markets.

Certain of the Company’s competitors initiated legal and/or regulatory challenges in 2010 and 2011 in multiple jurisdictions challenging Tennant’s advertising claims pertaining to its ec-H2O water-based technology. The majority of these claims have been closed with no material impact to the Company. The Company does not currently view the outstanding proceedings as material and does not expect the outcome to have a material adverse effect on the Company's operating results, financial condition or cash flows.

Research and Development

The Company strives to be an industry leader in innovation and is committed to investing in research and development. The Company’s Global Innovation Center in Minnesota and engineers throughout the global locations are dedicated to various activities including researching new technologies to create meaningful product differentiation, development of new products, improvements of existing product design or manufacturing processes and exploring new product applications with customers. In 2013, 2012 and 2011, the Company spent $30.5 million, $29.3 million and $27.9 million on research and development, respectively.

Environmental Compliance

Compliance with Federal, State and local provisions which have been enacted or adopted regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, has not had, and the Company does not expect it to have, a material effect upon the Company’s capital expenditures, earnings or competitive position.

Employees

The Company employed 2,931 people in worldwide operations as of December 31, 2013.

Available Information

The Company makes available free of charge, through the Company’s website at www.tennantco.com, its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable when such material is filed electronically with, or furnished to, the Securities and Exchange Commission (“SEC”).

ITEM 1A – Risk Factors

The following are significant factors known to us that could materially adversely affect our business, financial condition or operating results.

We may encounter financial difficulties if the United States or other global economies experience an additional or continued significant long-term economic downturn, decreasing the demand for our products.

Our product sales are sensitive to declines in capital spending by our customers. Decreased demand for our products could result in decreased revenues, profitability and cash flows and may impair our ability to maintain our operations and fund our obligations to others. In the event of a continued significant long-term economic downturn in the U.S. or other global economies, our revenues could decline to the point that we may have to take cost-saving measures to reduce our fixed costs to a level that is in line with a lower level of sales in order to stay in business long-term in a depressed economic environment.

We are subject to competitive risks associated with developing innovative products and technologies, including but not limited to, the risk that customers do not continue to pay for innovation and the risk of competitive challenges to our products and technology and the underlying intellectual property.

Our products are sold in competitive markets throughout the world. Competition is based on product features and design, brand recognition, reliability, durability, technology, breadth of product offerings, price, customer relationships and after-sale service. Although we believe that the performance and price characteristics of our products will produce competitive solutions for our customers’ needs, because of our dedication to innovation and continued investments in research and development, our products generally cost more than our competitors’ products. We believe that customers will pay for the innovations and quality in our products; however, in the current economic environment, it may be difficult for us to compete with lower cost products offered by our competitors and there can be no assurance that our customers will continue to choose our products over products offered by our competitors. If our products, markets and services are not competitive, we may experience a decline in sales, pricing and market share, which adversely impacts revenues, margin and the success of our operations.

In addition, we may be vulnerable to competitors who attempt to challenge our technology and our products or diminish the reputation of our brand, all of which could adversely affect our business. Certain of our competitors have previously initiated legal and regulatory actions against us and while we do not view these challenges to be material, defense of such claims may require substantial commitment of time and money and could potentially influence new customers from readily accepting our products, such as those with our ec-H2O technology, which could adversely affect our business.

Competitors may also initiate litigation to challenge the validity of our patents or claims, allege that we infringe upon their patents, violate our patents or they may use their resources to design comparable products that avoid infringing our patents. Regardless of whether such litigation is successful, such litigation could significantly increase our costs and divert management’s attention from the operation of our business, which could adversely affect our results of operations and financial condition.

Our ability to effectively operate our Company could be adversely affected if we are unable to attract and retain key personnel and other highly skilled employees.

Our continued success will depend on, among other things, the skills and services of our executive officers and other key personnel. Our ability to attract and retain other highly qualified managerial, technical, manufacturing, research, sales and marketing personnel also impacts our ability to effectively operate our business. As the economy recovers and companies grow and increase their hiring activities, there is an inherent risk of increased employee turnover and the loss of valuable employees in key positions, especially in emerging markets throughout the world. We believe the increased loss of key personnel within a concentrated region could adversely affect our sales growth.

4

We may not be able to upgrade and evolve our information technology systems as quickly as we wish and we may encounter difficulties as we upgrade and evolve these systems, which could adversely impact our abilities to accomplish anticipated future cost savings, better serve our customers and protect against information system disruption, corruption or intrusions.

We have many information technology systems that are important to the operation of our business and we have many information technology systems that are in need of upgrading. We may not have adequate resources to upgrade our systems at the pace which the current business environment demands. Inability to upgrade systems on a timely basis could increase our risk of a cybersecurity incident which could lead to interruptions, delays or cessation of systems, misappropriation of confidential information and corruption of data. Additionally, significantly upgrading and evolving the capabilities of our existing systems could lead to inefficient or ineffective use of our technology due to lack of training or expertise in these evolving technology systems. These factors could lead to significant expenses, adversely impacting our results of operations and hinder our ability to offer better technology solutions to our customers.

We may not be able to effectively manage organizational changes which could negatively impact our operating results or financial condition.

We are continuing to implement global standardized processes in our business despite lean staffing levels. We continue to consolidate and reallocate resources as part of our ongoing efforts to optimize our cost structure in the current economy. Our operating results may be negatively impacted if we are unable to implement new processes and manage organizational changes. In addition, if we do not effectively manage the implementation of new processes and organizational changes, we may not fully realize the anticipated savings of these actions or they may negatively impact our ability to serve our customers or meet our strategic objectives.

Inadequate or improper funding of new technologies may result in an inability to develop and commercialize new innovative products and services.

We strive to develop new and innovative products and services to differentiate ourselves in the marketplace. New product development relies heavily on our financial and resource investments in both the short term and long term. If we fail to adequately fund product development projects or fund a project which ultimately does not gain the market acceptance we anticipated, we risk not meeting our customers' expectations, which could result in decreased revenues, declines in margin and loss of market share.

Our global operations are subject to laws and regulations that impose significant compliance costs and create reputational and legal risk.

Due to the international scope of our operations, we are subject to a complex system of commercial, tax and trade regulations around the world. Recent years have seen an increase in the development and enforcement of laws regarding trade, tax compliance and anti-corruption such as the U.S. Foreign Corrupt Practices Act and similar laws from other countries. Our numerous foreign subsidiaries and affiliates are governed by laws, rules and business practices that differ from those of the U.S., but because we are a U.S. based company oftentimes they are also subject to U.S. laws, which can create a conflict. Despite our due diligence, it is possible that the activities of these entities may not comply with U.S. laws or business practices or our Business Ethics Guide. Violations of the U.S. or local laws may result in severe criminal or civil sanctions, could disrupt our business, and result in an adverse effect on our reputation, business and results of operations or financial condition. We cannot predict the nature, scope or effect of future regulatory requirements to which our operations might be subject or the manner in which existing laws might be administered or interpreted.

Increases in the cost, or disruption in the availability, of raw materials and components that we purchase could negatively impact our operating results or financial condition.

Our expanding geographical footprint and our continued use of sole source vendors coupled with suppliers’ potential credit issues could lead to an increased risk of a break-down in our supply chain. Purchased component parts are essential to our products and any defects in such parts could lead to quality issues, returns, production slow-downs or product liability risk. Modularization may lead to more sole sourced products and as we seek to outsource the design of certain key components, we risk loss of proprietary control and become more reliant on a sole source. The risk also exists that we will not be able to obtain adequate information from suppliers in order to comply with global disclosure requirements.

The SEC has adopted rules, with which we are required to comply, regarding the disclosure of the use of “conflict minerals” (commonly referred to as tin, tantalum, tungsten and gold) which are mined from the Democratic Republic of the Congo in products we manufacture or contract to manufacture. These minerals are present in a number of the Company's products. The discover and disclosure obligations are complex, and there is little formal guidance with respect to their application. Since our supply chain is complex, ultimately we may not be able to sufficiently discover the origin of the conflict minerals used in our products through the due diligence procedures that we implement, which may impact our ability to file a timely and/or accurate report with the SEC subjecting us to potential SEC enforcement risks. Additionally, if we are unable to or chose not to certify that our products are conflict mineral free, customers may choose not to purchase our products. Alternatively, if we chose to use only suppliers offering conflict free minerals, we cannot be sure that we will be able to obtain metals, if necessary, from such suppliers in sufficient quantities or at competitive prices. Any one or a combination of these various factors could harm our business, reduce market demand for our products, and adversely affect our profit margins, net sales, and overall financial results.

We are subject to product liability claims and product quality issues that could adversely affect our operating results or financial condition.

Our business exposes us to potential product liability risks that are inherent in the design, manufacturing and distribution of our products. If products are used incorrectly by our customers, injury may result leading to product liability claims against us. Some of our products or product improvements may have defects or risks that we have not yet identified that may give rise to product quality issues, liability and warranty claims. If product liability claims are brought against us for damages that are in excess of our insurance coverage or for uninsured liabilities and it is determined we are liable, our business could be adversely impacted. Any losses we suffer from any liability claims, and the effect that any product liability litigation may have upon the reputation and marketability of our products, may have a negative impact on our business and operating results. We could experience a material design or manufacturing failure in our products, a quality system failure, other safety issues, or heightened regulatory scrutiny that could warrant a recall of some of our products. Any unforeseen product quality problems could result in loss of market share, reduced sales, and higher warranty expense.

5

We may be unable to conduct business if we experience a significant business interruption in our computer systems, manufacturing plants or distribution facilities for a significant period of time.

We rely on our computer systems, manufacturing plants and distribution facilities to efficiently operate our business. If we experience an interruption in the functionality in any of these items for a significant period of time, we may not have adequate business continuity planning contingencies in place to allow us to continue our normal business operations on a long-term basis. Significant long-term interruption in our business could cause a decline in sales, an increase in expenses and could adversely impact our operating results.

ITEM 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

Tennant Company is a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world. Our products include equipment for maintaining surfaces in industrial, commercial and outdoor environments; chemical-free and other sustainable cleaning technologies; and coatings for protecting, repairing and upgrading floors and other surfaces. We sell our products through our direct sales and service organization and a network of authorized distributors worldwide. Geographically, our customers are located in North America, Latin America, Europe, the Middle East, Africa and Asia Pacific. We strive to be an innovator in our industry through our commitment to understanding our customers’ needs and using our expertise to create innovative products and solutions.

Net Sales in 2013 totaled $752.0 million, up from $739.0 million in the prior year primarily due to increased sales of industrial equipment and high demand for newly introduced products which were somewhat offset by lower sales of city cleaning equipment. 2013 organic sales growth, excluding the impact of foreign currency exchange, was up approximately 2.8% with growth in North America, Latin America and Asia Pacific being somewhat offset by declines in Europe due to challenging economic conditions. 2013 Gross Profit margin decreased 70 basis points to 43.3% from 44.0% in 2012 due to changes in selling channel mix and mix of products sold. Selling and Administrative Expense (“S&A Expense”) decreased 0.5%, or 70 basis points as a percentage of Net Sales, from $234.1 million in 2012 to $233.0 million in 2013 due to continued tight cost controls and improved operating leverage. Operating Profit decreased 0.5% and Operating Profit margin declined 20 basis points to 8.3% in 2013 from 8.5% in 2012 due to two restructuring charges taken during 2013 totaling $3.0 million and increased investment in R&D activities. Net Earnings for 2013 were favorably impacted by a tax benefit of $0.6 million related to the 2012 R&D tax credit which was retroactively enacted in January of 2013.

Net Earnings for 2012 were $8.9 million greater than 2011 despite a Net Sales decline of 2.0%. 2012 Gross Profit margin increased 170 basis points to 44.0% from 42.3% in 2011 due to favorable product mix, stable commodity costs and production efficiencies. Net Sales in 2012 totaled $739.0 million, which was down from $754.0 million in the prior year primarily due to lower sales unit volume in Europe stemming from weak economic conditions. 2012 organic sales growth, excluding the impact of foreign currency exchange, was essentially flat with growth in the Americas and emerging markets being offset by declines in the mature international markets. S&A Expense decreased 3.1%, or 30 basis points as a percentage of Net Sales, from $241.6 million in 2011 to $234.1 million in 2012 due to continued tight cost controls and improved operating leverage. Operating Profit increased 26.3% and Operating Profit margin improved 190 basis points to 8.5% in 2012 from 6.6% in 2011 due to higher Gross Profits and improved operating leverage. Net Earnings for 2012 were also favorably impacted by a $2.0 million tax benefit from an international entity restructuring.

Tennant continues to invest in innovative product development with 4.1% of 2013 Net Sales spent on R&D. During 2013 there were increased investments in developing innovative new products for our traditional core business, as well as our Orbio business.

We ended 2013 with a Debt-to-Capital ratio of 10.8%, $81.0 million in Cash and Cash Equivalents compared to $53.9 million at the end of 2012, and Shareholders’ Equity of $263.8 million. During 2013, we generated operating cash flows of $59.8 million. Total debt was $31.8 million as of December 31, 2013 compared to $32.3 million at the end of 2012.

Consolidated Financial Results

Net Earnings for 2013 were $40.2 million, or $2.14 per diluted share, compared to $41.6 million, or $2.18 per diluted share for 2012. Net Earnings were impacted by:

• An increase in Net Sales of 1.8%, primarily due to increased sales of industrial equipment andhigh demand for newly introduced products which were somewhat offset by lower sales of city cleaning equipment.

• A 70 basis point decrease in Gross Profit margin due to changes in selling channel mix and mix of products sold.

• A decrease in S&A Expense as a percentage of Net Sales of 70 basis points due to continued tight cost controls and improved operating efficiencies.

• Two restructuring actions totaling $3.0 million (pre-tax) during 2013 or 40 basis points as a percentage of Net Sales.

• A $0.6 million tax benefit related to the 2012 R&D tax credit which was retroactively enacted in January 2013.

Net Earnings for 2012 were $41.6 million, or $2.18 per diluted share, compared to $32.7 million, or $1.69 per diluted share for 2011. Net Earnings were impacted by:

• A decrease in Net Sales of 2.0%, primarily due to lower sales unit volume in Europe stemming from weak economic conditions.

• A 170 basis point increase in Gross Profit margin due to favorable product mix, stable commodity costs and production efficiencies.

• A decrease in S&A Expense as a percentage of Net Sales of 30 basis points due to continued tight cost controls and improved operating efficiencies.

• A tax benefit from an international entity restructuring contributed $0.11 per diluted share.

Net Sales

In 2013, consolidated Net Sales were $752.0 million, an increase of 1.8% as compared to 2012. Consolidated Net Sales were $739.0 million in 2012, a decrease of 2.0% as compared to 2011.

The components of the consolidated Net Sales change for 2013 as compared to 2012, and 2012 as compared to 2011, were as follows:

Growth Elements	2013 v. 2012	2012 v. 2011
Organic Growth:
Volume	1.8%	(1.0%)
Price	1.0%	1.0%
Organic Growth	2.8%	0%
Foreign Currency	(1.0%)	(2.0%)
Total	1.8%	(2.0%)

The 1.8% increase in consolidated Net Sales for 2013 as compared to 2012 was primarily due to sales volume increases due to increased sales of industrial equipment and demand for newly introduced products.

The 2.0% decrease in consolidated Net Sales for 2012 as compared to 2011 was primarily due to the impact of an unfavorable foreign currency exchange.

The following table sets forth annual Net Sales by operating segment and the related percentage change from the prior year (in thousands, except percentages):

	2013		%		2012		%		2011
Americas	$	514,544	4.7		$	491,661	2.1		$	481,426
Europe, Middle East and Africa	157,208		(5.4	)	166,208		(11.8	)	188,338
Asia Pacific	80,259		(1.1	)	81,111		(3.7	)	84,234
Total	$	752,011	1.8		$	738,980	(2.0	)	$	753,998

Americas – In 2013, Americas Net Sales increased 4.7% to $514.5 million as compared with $491.7 million in 2012. The primary driver of the increase in Net Sales was attributable to higher sales of equipment in North America, including scrubbers equipped with ec-H2O technology and sweepers, and continued growth in Latin America. Unfavorable direct foreign currency translation exchange effects decreased Net Sales by approximately 1.0%.

In 2012, Americas Net Sales increased 2.1% to $491.7 million as compared with $481.4 million in 2011. The primary driver of the increase in Net Sales was attributable to sales unit volume increases with higher sales to strategic accounts, continued growth of scrubbers equipped with our ec-H2O technology and double-digit growth in Latin America. Unfavorable direct foreign currency translation exchange effects decreased Net Sales by approximately 1.0%.

Europe, Middle East and Africa – Europe, Middle East and Africa (“EMEA”) Net Sales in 2013 decreased 5.4% to $157.2 million as compared to 2012 Net Sales of $166.2 million. An organic sales decrease of approximately 7.4% was primarily due to decreases in sales of city cleaning equipment due to tight municipal spending in Europe, somewhat offset by increased sales to strategic accounts. Favorable direct foreign currency exchange effects increased EMEA Net Sales by approximately 2.0% in 2013.

EMEA Net Sales in 2012 decreased 11.8% to $166.2 million as compared to 2011 Net Sales of $188.3 million. An organic sales decrease of approximately 6.3% was primarily due to sales unit volume decreases, particularly industrial equipment, due to continued economic uncertainty. Unfavorable direct foreign currency exchange effects decreased EMEA Net Sales by approximately 5.5% in 2012.

Asia Pacific – Asia Pacific Net Sales in 2013 decreased 1.1% to $80.3 million as compared to 2012 Net Sales of $81.1 million. An organic sales increase of approximately 4.4% was primarily due to increased sales of equipment in China and also sales growth in Australia and Japan. Unfavorable direct foreign currency exchange effects decreased Net Sales by approximately 5.5% in 2013.

Asia Pacific Net Sales in 2012 decreased 3.7% to $81.1 million over 2011 Net Sales of $84.2 million. An organic sales decrease of approximately 4.2% was primarily due to sales unit volume decreases in mature markets, particularly Australia, somewhat offset by growth in China. Favorable direct foreign currency exchange effects increased Net Sales by approximately 0.5% in 2012.

Gross Profit

Gross Profit margin was 43.3% in 2013, a decrease of 70 basis points as compared to 2012. Gross Profit margin in 2013 was unfavorably impacted by changes in selling channel mix and the mix of products sold.

Gross Profit margin was 44.0% in 2012, an increase of 170 basis points as compared to 2011. Gross Profit margin in 2012 was favorably impacted by favorable product mix, stable commodity costs and production efficiencies.

11

Operating Expenses

Research and Development Expense – R&D Expense increased $1.3 million, or 4.3%, in 2013 as compared to 2012. As a percentage of Net Sales, 2013 R&D Expense increased 10 basis points to 4.1% in 2013 from 4.0% in the prior year. R&D Expense increased in 2013 as we made additional investments in developing innovative new products for our traditional core business, as well as our Orbio business.

R&D Expense increased $1.4 million, or 4.8%, in 2012 as compared to 2011. As a percentage of Net Sales, 2012 R&D Expense increased 30 basis points to 4.0% in 2012 from 3.7% in the prior year. R&D Expense increased in 2012 as we made additional investments in our chemical-free and other sustainable cleaning technologies as well as our core business including the work to redesign our large equipment portfolio.

Selling and Administrative Expense – S&A Expense decreased by $1.1 million, or 0.5%, in 2013 compared to 2012. As a percentage of Net Sales, 2013 S&A Expense decreased 70 basis points to 31.0% due to continued tight cost controls and improved operating efficiencies. Included in the lower S&A Expense during 2013 were two restructuring actions totaling $3.0 million, or 40 basis points as a percentage of Net Sales.

S&A Expense decreased by $7.5 million, or 3.1%, in 2012 compared to 2011. As a percentage of Net Sales, 2012 S&A Expense decreased 30 basis points to 31.7% due to continued tight cost controls and improved operating efficiencies.

Other Income (Expense)

Interest Income – Interest Income was $0.4 million in 2013, a decrease of $0.7 million from 2012. The decrease between 2013 and 2012 was due to decreases in interest rates on cash invested.

Interest Income was $1.1 million in 2012, an increase of $0.3 million from 2011. The increase between 2012 and 2011 was due to an increase in cash invested.

Interest Expense – Interest Expense was $1.8 million in 2013 as compared to $2.5 million in 2012. This decrease was primarily due to lower interest rates on long-term adjustable rate borrowings.

Interest Expense was $2.5 million in 2012 as compared to $2.2 million in 2011. This increase was primarily due to a higher interest rate related to long-term fixed rate borrowings initiated in 2011.

Net Foreign Currency Transaction (Losses) Gains – Net Foreign Currency Transaction Losses were $0.7 million in 2013 as compared to Losses of $1.4 million in 2012. The favorable decrease from the prior year was due to fluctuations in foreign currency rates in the normal course of business.

Net Foreign Currency Transaction Losses were $1.4 million in 2012 as compared to Gains of $0.6 million in 2011. The unfavorable decrease from the prior year was due to fluctuations in foreign currency rates in the normal course of business.

Income Taxes

The overall effective income tax rate was 32.8%, 30.6% and 32.9% in 2013, 2012 and 2011, respectively. The tax expense for 2013 includes a $0.1 million tax benefit associated with restructuring charges of $3.0 million. The tax expense also includes a first quarter discrete tax benefit of $0.6 million for the enactment of the Federal R&D credit retroactively impacting the tax year ended December 31, 2012. Excluding these special items, the overall effective tax rate would have been 32.3%.

The tax expense for 2012 included a $2.0 million tax benefit associated with an international entity restructuring which materially decreased the overall effective tax rate. Excluding this tax benefit, the overall effective tax rate would have been 34.0%.

The decrease in the 2013 overall effective tax rate as compared to the prior year, excluding the effect of these special items, was primarily related to the mix in our full year taxable earnings by country and more favorable discrete items in 2013.

The 2011 net tax expense included only a $0.5 million tax benefit in the second quarter associated with the $5.5 million pre-tax charges related to Hofmans product obsolescence and international executive severance, materially impacting the overall effective rate. Excluding these charges, the 2011 overall rate would have been 30.4%.

We do not have any plans to repatriate the undistributed earnings of non-U.S. subsidiaries. Any repatriation from foreign subsidiaries that would result in incremental U.S. taxation is not being considered. It is management's belief that reinvesting these earnings outside the U.S. is the most efficient use of capital.

Liquidity and Capital Resources

Liquidity – Cash and Cash Equivalents totaled $81.0 million at December 31, 2013, as compared to $53.9 million as of December 31, 2012. Cash and Cash Equivalents held by our foreign subsidiaries totaled $13.4 million as of December 31, 2013 as compared to $10.6 million as of December 31, 2012. Wherever possible, cash management is centralized and intercompany financing is used to provide working capital to subsidiaries as needed. Our current ratio was 2.4 as of December 31, 2013 and 2.2 as of December 31, 2012, and our working capital was $183.8 million and $151.8 million, respectively.

Our Debt-to-Capital ratio was 10.8% as of December 31, 2013, compared with 12.1% as of December 31, 2012. Our capital structure was comprised of $31.8 million of Debt and $263.8 million of Shareholders’ Equity as of December 31, 2013.

Cash Flow Summary – Cash provided by (used in) our operating, investing and financing activities is summarized as follows (in thousands):

	2013			2012			2011
Operating Activities	$	59,814		$	47,566		$	56,909

Effect of Exchange Rate Changes on Cash and Cash Equivalents	122			209			(355		)
Net Increase in Cash and Cash Equivalents	$	27,044		$	1,601		$	12,810

Operating Activities – Cash provided by operating activities was $59.8 million in 2013, $47.6 million in 2012 and $56.9 million in 2011. In 2013, cash provided by operating activities was driven by $40.2 million of Net Earnings and an increase in Accounts Payable, somewhat offset by increases in Inventories and Receivables. The increase in Inventories was in support of the launches of many new products. The increase in Receivables was due to a variety of terms offered and mix of business. Cash provided by operating activities was $12.2 million higher in 2013 as compared to 2012 primarily due to a $15.0 million discretionary contribution made to the U.S. Pension Plan in 2012 and there were no contributions made in 2013.

12

In 2012, cash provided by operating activities was driven by $41.6 million of Net Earnings and an increase in Accounts Receivable, somewhat offset by a decrease in accrued Employee Compensation and Benefits. The increase in Accounts Receivables was due to a variety of terms offered and mix of business. Cash provided by operating activities was $9.3 million lower in 2012 as compared to 2011 primarily due to a $15.0 million discretionary contribution made to the U.S. Pension Plan in December 2012.

For 2013, we used operating profit and operating profit margin as key indicators of financial performance and the primary metrics for performance-based incentives.

Two metrics used by management to evaluate how effectively we utilize our net assets are “Accounts Receivable Days Sales Outstanding” (“DSO”) and “Days Inventory on Hand” (“DIOH”), on a first-in, first-out (“FIFO”) basis. The metrics are calculated on a rolling three month basis in order to more readily reflect changing trends in the business. These metrics for the quarters ended December 31 were as follows (in days):

	2013	2012	2011
DSO	61	60	58
DIOH	81	78	88

DSO increased 1 day in 2013 as compared to 2012 primarily due to the variety of terms offered and mix of business having a larger unfavorable impact than the favorable trend of continued proactive management of our receivables by enforcing tighter credit limits and continuing to successfully collect past due balances.

DIOH increased 3 days in 2013 as compared to 2012 primarily due to increased levels of inventory in support of the launches of many new products somewhat offset by progress from inventory reduction initiatives.

Investing Activities – Net cash used for investing activities was $11.4 million in 2013, $11.2 million in 2012 and $19.5 million in 2011. Net capital expenditures were $14.7 million during 2013 as compared to $14.6 million in 2012 and $13.3 million in 2011. Our 2013 capital expenditures included investments in tooling related to new product development, and manufacturing and information technology process improvement projects. Proceeds from Sale of Business provided $4.3 million in 2013 and $1.0 million in 2012.

Capital expenditures in 2012 included tooling related to new product development, manufacturing equipment and information technology process improvement projects. Capital expenditures in 2011 included tooling related to new product development, investments in our facilities including the new plant in China, technology upgrades, and manufacturing and lab equipment.

Financing Activities – Net cash used for financing activities was $21.5 million in 2013, $34.9 million in 2012 and $24.2 million in 2011. In 2013, payments of dividends used $13.2 million and payments of Long-Term Debt used $1.1 million, partially offset by Short-Term Borrowings of $1.5 million. In 2012, payments of Long-Term Debt used $3.0 million and payments of dividends used $12.8 million. In 2011, payments of Long-Term Debt used $19.3 million, which was more than offset by a $20.0 million issuance of fixed rate Long-Term Debt, and payments of dividends used $12.9 million. Our annual cash dividend payout increased for the 42^nd consecutive year to $0.72 per share in 2013, an increase of $0.03 per share over 2012.

Proceeds from the issuance of Common Stock generated $8.3 million in 2013, $4.2 million in 2012 and $4.2 million in 2011.

On April 25, 2012, the Board of Directors authorized the repurchase of 1,000,000 shares of our common stock. This was in addition to the 618,050 shares remaining under our current repurchase program at that time. At December 31, 2013, there were 630,603 remaining shares authorized for repurchase.

There were 434,118 shares repurchased in 2013 in the open market, 621,340 shares repurchased in 2012 and 469,304 shares repurchased during 2011, at average repurchase prices of $51.04 during 2013, $40.78 during 2012 and $37.51 during 2011. Our Credit Agreement with JPMorgan Chase Bank limits the payment of dividends and repurchases of stock to amounts ranging from $50.0 million to $75.0 million per fiscal year based on our leverage ratio after giving effect to such payments for the life of the agreement.

Indebtedness – As of December 31, 2013, we had committed lines of credit totaling approximately $125.0 million and uncommitted lines of credit totaling approximately $87.8 million. There were $10.0 million outstanding borrowings under our JPMorgan facility, $20.0 million outstanding borrowings under our Prudential facility and $1.5 million outstanding under the facility with HSBC Shanghai as of December 31, 2013. In addition, we had stand alone letters of credit of approximately $2.1 million outstanding and bank guarantees in the amount of approximately $0.5 million. Commitment fees on unused lines of credit for the year ended December 31, 2013 were $0.3 million.

Our most restrictive covenants are part of our Credit Agreement with JPMorgan, which are the same covenants in our Shelf Agreement with Prudential described below, and require us to maintain an indebtedness to EBITDA ratio of not greater than 3.00 to 1 and to maintain an EBITDA to interest expense ratio of no less than 3.50 to 1 as of the end of each quarter. As of December 31, 2013, our indebtedness to EBITDA ratio was 0.41 to 1 and our EBITDA to interest expense ratio was 48.00 to 1.

Credit Facilities

JPMorgan Chase Bank, National Association

On April 25, 2013, we entered into Amendment No. 1 to our 2011 Credit Agreement which amends the Credit Agreement, dated as of May 5, 2011, with JPMorgan Chase Bank, N. A. (“JPMorgan”), as administrative agent and collateral agent, U.S. Bank National Association, as syndication agent, Wells Fargo Bank, National Association, and RBS Citizens, N.A., as co-documentation agents, and the Lenders (including JPMorgan) from time to time party thereto (the “2011 Credit Agreement”). Under the original terms, the 2011 Credit Agreement provides us and certain of our foreign subsidiaries access to a senior unsecured credit facility until May 5, 2016, in the amount of $125.0 million, with an option to expand by up to $62.5 million to a total of $187.5 million. Borrowings may be denominated in U.S. Dollars or certain other currencies. The 2011 Credit Agreement contains a $100.0 million sublimit on borrowings by foreign subsidiaries.

Under the original terms of the 2011 Credit Agreement, the fee for committed funds ranges from an annual rate of 0.25% to 0.40%, depending on our leverage ratio. Eurocurrency borrowings under the 2011 Credit Agreement bear interest at a rate per annum equal to adjusted LIBOR plus an additional spread of 1.50% to 2.10%, depending on our leverage ratio. Alternate Base Rate (“ABR”) borrowings bear interest at a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.50% to 1.10%, depending on our leverage ratio.

13

Effective April 25, 2013, Amendment No. 1 to the 2011 Credit Agreement principally provides the following changes to the 2011 Credit Agreement:

• extends the maturity date of the 2011 Credit Agreement to March 1, 2018;

• changes the fees for committed funds under the 2011 Credit Agreement to an annual rate ranging from 0.20% to 0.35%, depending on our leverage ratio;

• changes the per annum interest rate on Eurocurrency borrowings to adjusted LIBOR plus an additional spread of 1.30% to 1.90%, depending on our leverage ratio;

• changes the ABR rate at which borrowings bear interest to a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.30% to 0.90%, depending on our leverage ratio; and

• changes related to new or recently revised financial regulations.

The 2011 Credit Agreement gives the Lenders a pledge of 65% of the stock of certain first tier foreign subsidiaries. The obligations under the 2011 Credit Agreement are also guaranteed by certain of our first tier domestic subsidiaries.

The 2011 Credit Agreement contains customary representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and merge or consolidate with another entity. Further, the 2011 Credit Agreement contains the following covenants:

• a covenant requiring us to maintain an indebtedness to EBITDA ratio as of the end of each quarter of not greater than 3.00 to 1;

• a covenant requiring us to maintain an EBITDA to interest expense ratio as of the end of each quarter of no less than 3.50 to 1;

• a covenant restricting us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50.0 million to $75.0 million during any fiscal year based on our leverage ratio after giving effect to such payments; and

• a covenant restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25.0 million.

As of December 31, 2013 we were in compliance with all covenants under the Credit Agreement. There was $10.0 million in outstanding borrowings under this facility at December 31, 2013, with a weighted average interest rate of 1.47%.

Prudential Investment Management, Inc.

On July 29, 2009, we entered into a Private Shelf Agreement (the “Shelf Agreement”) with Prudential Investment Management, Inc. (“Prudential”) and Prudential affiliates from time to time party thereto. The Shelf Agreement provides us and our subsidiaries access to an uncommitted, senior secured, maximum aggregate principal amount of $80.0 million of debt capital. The Shelf Agreement contains representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and to merge or consolidate with another entity. The Shelf Agreement limits the payment of dividends or repurchases of stock to an amount ranging from $12.0 million to $40.0 million based on our leverage ratio after giving effect to such payments.

On May 5, 2011, we entered into Amendment No. 1 to our Private Shelf Agreement (the “Amendment”).

The Amendment principally provides the following changes to the Shelf Agreement:

• elimination of the security interest in our personal property and subsidiaries;

• an amendment to the maximum leverage ratio to not greater than 3.00 to 1 for any period ending on or after March 31, 2011;

• an amendment to our restriction regarding the payment of dividends or repurchase of stock to restrict us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50.0 million to $75.0 million during any fiscal year based on our leverage ratio after giving effect to such payments; and

• an amendment to Permitted Acquisitions restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25.0 million.

On July 24, 2012, we entered into Amendment No. 2 to our Private Shelf Agreement (“Amendment No. 2”), which amends the Shelf Agreement. The principal change effected by Amendment No. 2 is an extension of the Issuance Period for Shelf Notes under the Shelf Agreement. The Issuance Period now expires on July 24, 2015.

As of December 31, 2013, there was $20.0 million in outstanding borrowings under this facility; the $10.0 million Series A notes issued in March 2011 with a fixed interest rate of 4.00% and a 7 year term serially maturing from 2014 to 2018; and the $10.0 million Series B notes issued in June 2011 with a fixed interest rate of 4.10% and a 10 year term serially maturing from 2015 to 2021. We were in compliance with all covenants of the Shelf Agreement as of December 31, 2013.

The Royal Bank of Scotland Citizens, N.A.

On September 14, 2010, we entered into an overdraft facility with The Royal Bank of Scotland Citizens, N.A. in the amount of 2.0 million Euros or approximately $2.8 million. There was no balance outstanding on this facility as of December 31, 2013.

HSBC Bank (China) Company Limited, Shanghai Branch

On June 20, 2012, we entered into a banking facility with the HSBC Bank (China) Company Limited, Shanghai Branch in the amount of $5.0 million. There was $1.5 million in outstanding borrowings on this facility as of December 31, 2013, with a fixed interest rate of 5.1%.

Notes Payable

On May 31, 2011, we incurred $1.5 million in debt related to installment payments due to the former owners of Water Star, Inc. ("Water Star") in connection with our acquisition of Water Star, of which none remains outstanding as of December 31, 2013.

Collateralized Borrowings

Collateralized borrowings represent deferred sales proceeds on certain leasing transactions with third-party leasing companies. These transactions are accounted for as borrowings, with the related assets capitalized as property, plant and equipment and depreciated straight-line over the lease term.

14

Capital Lease Obligations

Capital lease obligations outstanding are primarily related to sale-leaseback transactions with third-party leasing companies whereby we sell our manufactured equipment to the leasing company and lease it back. The equipment covered by these leases is rented to our customers over the lease term.

Contractual Obligations – Our contractual obligations as of December 31, 2013, are summarized by period due in the following table (in thousands):

	Total		Less Than 1 Year		1 - 3 Years		3 - 5 Years		More Than 5 Years
Short-term Borrowings(1)	$	1,500	$	1,500	$	—	$	—	$	—
Long-term debt(2)	30,009		2,009		6,857		16,857		4,286
Interest payments on long-term debt(2)	3,360		898		1,438		760		264
Capital leases	283		283		—		—		—
Interest payments on capital leases	17		17		—		—		—
Retirement benefit plans(3)	1,346		1,346		—		—		—
Deferred compensation arrangements(4)	7,628		588		530		208		6,302
Operating leases(5)	19,886		8,398		8,507		2,670		311
Purchase obligations(6)	54,262		53,419		843		—		—
Other(7)	7,670		7,670		—		—		—
Total contractual obligations	$	125,961	$	76,128	$	18,175	$	20,495	$	11,163

(1)Short-term debt represents bank borrowings from our banking facility with HSBC Bank (China) Company Limited, Shanghai Branch. Amounts drawn on the facility are due within 1 year with a fixed interest rate of 5.1%.

(2)Long-term debt represents bank borrowings and borrowings through our Credit Agreement with JPMorgan and our Shelf Agreement with Prudential. Our Credit Agreement with JPMorgan does not have specified repayment terms; therefore, repayment is due upon expiration of the agreement on March 1, 2018. Interest payments on our Credit Agreement were calculated using the December 31, 2013 LIBOR rate based on the assumption that the principal would be repaid in full upon the expiration of the agreement. Our borrowings under our Shelf Agreement with Prudential have 7 and 10 year terms, serially maturing from 2014 to 2021 with fixed interest rates of 4.00% and 4.10%, respectively.

(3)Our retirement benefit plans, as described in Note 11 of the Consolidated Financial Statements, require us to make contributions to the plans from time to time. Our plan obligations totaled $5.9 million as of December 31, 2013. Contributions to the various plans are dependent upon a number of factors including the market performance of plan assets, if any, and future changes in interest rates, which impact the actuarial measurement of plan obligations. As a result, we have only included our 2014 expected contribution in the contractual obligations table.

(4)The unfunded deferred compensation arrangements covering certain current and retired management employees totaled $7.6 million as of

December 31, 2013. Our estimated distributions in the contractual obligations table are based upon a number of assumptions including termination dates and participant distribution elections.

(5)Operating lease commitments consist primarily of office and warehouse facilities, vehicles and office equipment as discussed in Note 13 of the Consolidated Financial Statements.

(6)Purchase obligations include all known open purchase orders, contractual purchase commitments and contractual obligations as of December 31, 2013.

(7)Other obligations include collateralized borrowings as discussed in Note 8 of the Consolidated Financial Statements and residual value guarantees as discussed in Note 13 of the Consolidated Financial Statements.

Total contractual obligations exclude our gross unrecognized tax benefits of $3.7 million and accrued interest and penalties of $0.5 million as of December 31, 2013. We expect to make cash outlays in the future related to uncertain tax positions. However, due to the uncertainty of the timing of future cash flows, we are unable to make reasonably reliable estimates of the period of cash settlement, if any, with the respective taxing authorities. For further information related to unrecognized tax benefits, see Note 14 of the Consolidated Financial Statements.

Newly Issued Accounting Guidance

Presentation of Unrecognized Tax Benefits

In July 2013, the Financial Accounting Standards Board 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. We do not expect this guidance to have a material impact on our results of operations or financial position.

No other new accounting pronouncements issued during 2013 but not yet effective has had, or is expected to have, a material impact on our results of operations or financial position.

15

Critical Accounting Policies and Estimates

Our Consolidated Financial Statements are based on the selection and application of accounting principles generally accepted in the United States of America, which require us to make estimates and assumptions about future events that affect the amounts reported in our Consolidated Financial Statements and the accompanying notes. Our significant accounting policies are described in Note 1 of the Consolidated Financial Statements. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may be material to the Consolidated Financial Statements. We believe that the following policies may involve a higher degree of judgment and complexity in their application and represent the critical accounting policies used in the preparation of our Consolidated Financial Statements. If different assumptions or conditions were to prevail, the results could be materially different from our reported results.

Allowance for Doubtful Accounts – We record a reserve for accounts receivable that are potentially uncollectible. A considerable amount of judgment is required in assessing the realization of these receivables including the current creditworthiness of each customer and related aging of the past-due balances. In order to assess the collectibility of these receivables, we perform ongoing credit evaluations of our customers’ financial condition. Through these evaluations, we may become aware of a situation where a customer may not be able to meet its financial obligations due to deterioration of its financial viability, credit ratings or bankruptcy. The reserve requirements are based on the best facts available to us and are reevaluated and adjusted as additional information becomes available. Our reserves are also based on amounts determined by using percentages applied to trade receivables. These percentages are determined by a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. We are not able to predict changes in the financial condition of our customers and if circumstances related to these customers deteriorate, our estimates of the recoverability of accounts receivable could be materially affected and we may be required to record additional allowances. Alternatively, if more allowances are provided than are ultimately required, we may reverse a portion of such provisions in future periods based on the actual collection experience. Bad debt write-offs as a percentage of Net Sales were approximately 0.2% in 2013, 0.3% in 2012 and 0.2% in 2011. As of December 31, 2013, we had $4.5 million reserved against Accounts Receivable for doubtful accounts.

Inventory Reserves – We value our inventory at the lower of the cost of inventory or fair market value through the establishment of a reserve for excess, slow moving and obsolete inventory. In assessing the ultimate realization of inventories, we are required to make judgments as to future demand requirements compared with inventory levels. Reserve requirements are developed by comparing our inventory levels to our projected demand requirements based on historical demand, market conditions and technological and product life cycle changes. It is possible that an increase in our reserve may be required in the future if there are significant declines in demand for certain products. This reserve creates a new cost basis for these products and is considered permanent. As of December 31, 2013, we had $3.3 million reserved against Inventories.

Goodwill – Goodwill represents the excess of cost over the fair value of net assets of businesses acquired and is allocated to our reporting units at the time of the acquisition. We analyze Goodwill on an annual basis and when an event occurs or circumstances change that may reduce the fair value of one of our reporting units below its carrying amount. A goodwill impairment loss occurs if the carrying amount of a reporting unit’s goodwill exceeds its fair value.

We performed an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform

the two-step quantitative goodwill impairment test. The first step of the two-step model is used as an indicator to identify if there is potential goodwill impairment. If the first step indicates there may be an impairment, the second step is performed which measures the amount of the goodwill impairment, if any. We perform our goodwill impairment analysis as of year end and use our judgment to develop assumptions for the discounted cash flow model that we use, if necessary. Management assumptions include forecasting revenues and margins, estimating capital expenditures, depreciation, amortization and discount rates.

If our goodwill impairment testing resulted in one or more of our reporting units’ carrying amount exceeding its fair value, we would write down our reporting units’ carrying amount to its fair value and would record an impairment charge in our results of operations in the period such determination is made. Subsequent reversal of goodwill impairment charges is not permitted. Each of our reporting units were analyzed for impairment as of December 31, 2013 and based upon our analysis, the estimated fair values of our reporting units substantially exceeded their carrying amounts. We had Goodwill of $18.9 million as of December 31, 2013.

Warranty Reserves – We record a liability for warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to net sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. Future claims experience could be materially different from prior results because of the introduction of new, more complex products, a change in our warranty policy in response to industry trends, competition or other external forces, or manufacturing changes that could impact product quality. In the event we determine that our current or future product repair and replacement costs exceed our estimates, an adjustment to these reserves would be charged to earnings in the period such determination is made. Warranty expense as a percentage of Net Sales was 1.4% in 2013, 1.7% in 2012 and 1.7% in 2011. As of December 31, 2013, we had $9.7 million reserved for future estimated warranty costs.

Income Taxes – We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax obligations based on expected income, statutory tax rates and tax planning opportunities in the various jurisdictions. We also establish reserves for uncertain tax matters that are complex in nature and uncertain as to the ultimate outcome. Although we believe that our tax return positions are fully supportable, we consider our ability to ultimately prevail in defending these matters when establishing these reserves. We adjust our reserves in light of changing facts and circumstances, such as the closing of a tax audit. We believe that our current reserves are adequate. However, the ultimate outcome may differ from our estimates and assumptions and could impact the income tax expense reflected in our Consolidated Statements of Earnings.

Tax law requires certain items to be included in our tax return at different times than the items are reflected in our results of operations. Some of these differences are permanent, such as expenses that are not deductible in our tax returns, and some differences will reverse over time, such as depreciation expense on property, plant and equipment. These temporary differences result in deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. Deferred tax assets generally represent items that can be used as a tax deduction or credit in our tax returns in future years but have already been recorded as an expense in our Consolidated Statements of Earnings. We assess the likelihood that our deferred tax assets will be recovered from future taxable income, and, based on management’s judgment, to the extent we believe that recovery is not more likely than not, we establish a valuation reserve against those deferred tax assets. The deferred tax asset valuation allowance could be materially different from actual results because of changes in the mix of future taxable income, the relationship between book and taxable income and our tax planning strategies. As of December 31, 2013, a valuation allowance of $7.2 million was recorded against foreign tax loss carry-forwards and state credit carry-forwards.

Cautionary Factors Relevant to Forward-Looking Information

This annual report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 2, contain certain statements that are considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “project,” or “continue” or similar words or the negative thereof. These statements do not relate to strictly historical or current facts and provide current expectations of forecasts of future events. Any such expectations or forecasts of future events are subject to a variety of factors. Particular risks and uncertainties presently facing us include:

• Geopolitical and economic uncertainty throughout the world.

• Competition in our business.

• Ability to attract and retain key personnel.

• Ability to successfully upgrade, evolve and protect our information technology systems.

• Ability to effectively manage organizational changes.

• Ability to develop and commercialize new innovative products and services.

• Ability to comply with laws and regulations.

• Fluctuations in the cost or availability of raw materials and purchased components.

• Unforeseen product liability claims or product quality issues.

• Occurrence of a significant business interruption.

• Relative strength of the U.S. dollar, which affects the cost of our materials and products purchased and sold internationally.

We caution that forward-looking statements must be considered carefully and that actual results may differ in material ways due to risks and uncertainties both known and unknown. Information about factors that could materially affect our results can be found in Part I, Item 1A - Risk Factors. Shareholders, potential investors and other readers are urged to consider these factors in evaluating forward-looking statements and are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. Investors are advised to consult any further disclosures by us in our filings with the Securities and Exchange Commission and in other written statements on related subjects. It is not possible to anticipate or foresee all risk factors, and investors should not consider any list of such factors to be an exhaustive or complete list of all risks or uncertainties.

ITEM 7A – Quantitative and Qualitative Disclosures About Market Risk

Commodity Risk –We are subject to exposures resulting from potential cost increases related to our purchase of raw materials or other product components. We do not use derivative commodity instruments to manage our exposures to changes in commodity prices such as steel, oil, gas, lead and other commodities.

Various factors beyond our control affect the price of oil and gas, including but not limited to worldwide and domestic supplies of oil and gas, political instability or armed conflict in oil-producing regions, the price and level of foreign imports, the level of consumer demand, the price and availability of alternative fuels, domestic and foreign governmental regulation, weather-related factors and the overall economic environment. We purchase petroleum-related component parts for use in our manufacturing operations. In addition, our freight costs associated with shipping and receiving product and sales and service vehicle fuel costs are impacted by fluctuations in the cost of oil and gas.

Increases in worldwide demand and other factors affect the price for lead, steel and related products. We do not maintain an inventory of raw or fabricated steel or batteries in excess of near-term production requirements. As a result, increases in the price of lead or steel can significantly increase the cost of our lead- and steel-based raw materials and component parts.

During the first part of 2013, our raw materials and other purchased component costs were unfavorably impacted by commodity prices although we were able to somewhat mitigate these higher costs with pricing actions and cost reduction activities. We continue to focus on mitigating the risk of continued future raw material or other product component cost increases through product pricing, negotiations with our vendors and cost reduction actions. The success of these efforts will depend upon our ability to increase our selling prices in a competitive market and our ability to achieve cost savings. If the commodity prices increase significantly and we are not able to offset the increases with higher selling prices, our results may be unfavorably impacted in 2014.

Foreign Currency Exchange Risk –Due to the global nature of our operations, we are subject to exposures resulting from foreign currency exchange fluctuations in the normal course of business. Our primary exchange rate exposures are with the Euro, Australian and Canadian dollars, British pound, Japanese yen, Chinese yuan and Brazilian real against the U.S. dollar. The direct financial impact of foreign currency exchange includes the effect of translating profits from local currencies to U.S. dollars, the impact of currency fluctuations on the transfer of goods between our operations in the United States and abroad and transaction gains and losses. In addition to the direct financial impact, foreign currency exchange has an indirect financial impact on our results, including the effect on sales volume within local economies and the impact of pricing actions taken as a result of foreign exchange rate fluctuations.

It is not possible to determine the exact impact of foreign currency translation changes. However, the direct effect on reported net sales can be estimated. For the year ended December 31, 2013, the impact of foreign currency translation resulted in an overall approximate 1% decrease in reported Net Sales. For details of the effects of currency translation on Net Sales of Tennant Company's operating segments, see Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations.

17

Our objective in managing the exposure to foreign currency fluctuations is to minimize the earnings effects associated with foreign exchange rate changes on certain of our foreign currency-denominated assets and liabilities. We periodically enter into various contracts, principally forward exchange contracts, to protect the value of certain of our foreign currency-denominated assets and liabilities. The gains and losses on these contracts generally approximate changes in the value of the related assets and liabilities. We had forward exchange contracts outstanding in the notional amounts of $30.3 million and $42.5 million at the end of 2013 and 2012, respectively. For further information regarding our foreign currency forward exchange contracts, see Note 10 of the Consolidated Financial Statements. The potential for material loss in fair value of foreign currency contracts outstanding and the related underlying exposures as of December 31, 2013, from a 10% adverse change is unlikely due to the short-term nature of our forward contracts. Our policy prohibits us from entering into transactions for speculative purposes.

Other Matters –Management regularly reviews our business operations with the objective of improving financial performance and maximizing our return on investment. As a result of this ongoing process to improve financial performance, we may incur additional restructuring charges in the future which, if taken, could be material to our financial results.

ITEM 8 – Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Tennant Company:

We have audited the accompanying consolidated balance sheets of Tennant Company and subsidiaries (the Company) as of December 31, 2013 and 2012, and the related consolidated statements of earnings, comprehensive income, cash flows, and shareholders’ equity for each of the years in the three-year period ended December 31, 2013. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule as included in Item 15.A.2. We also have audited the Company’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule, and an opinion on the Company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Tennant Company and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the accompanying financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. Furthermore, in our opinion, Tennant Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except shares and per share data)

1. Summary of Significant Accounting Policies

Nature of Operations – Our primary business is designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world. Our products include equipment for maintaining surfaces in industrial, commercial and outdoor environments; chemical-free and other sustainable cleaning technologies; and coatings for protecting, repairing and upgrading floors and other surfaces. We sell our products through our direct sales and service organization and a network of authorized distributors worldwide. Geographically, our customers are located in North America, Latin America, Europe, the Middle East, Africa and Asia Pacific.

Consolidation – The Consolidated Financial Statements include the accounts of Tennant Company and its subsidiaries. All intercompany transactions and balances have been eliminated. In these Notes to the Consolidated Financial Statements, Tennant Company is referred to as “Tennant,” “we,” “us,” or “our.”

Translation of Non-U.S. Currency – Foreign currency-denominated assets and liabilities have been translated to U.S. dollars at year-end exchange rates, while income and expense items are translated at average exchange rates prevailing during the year. Gains or losses resulting from translation are included as a separate component of Accumulated Other Comprehensive Loss. The balance of cumulative foreign currency translation adjustments recorded within Accumulated Other Comprehensive Loss as of December 31, 2013, 2012 and 2011 was a net loss of $21,991, $19,734 and $20,283, respectively. The majority of translation adjustments are not adjusted for income taxes as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Net Foreign Currency Transaction (Losses) Gains are included in Other Income (Expense).

Use of Estimates – In preparing the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), management must make decisions that impact the reported amounts of assets, liabilities, revenues, expenses and the related disclosures, including disclosures of contingent assets and liabilities. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. Estimates are used in determining, among other items, sales promotions and incentives accruals, inventory valuation, warranty reserves, allowance for doubtful accounts, pension and postretirement accruals, useful lives for intangible assets, and future cash flows associated with impairment testing for goodwill and other long-lived assets. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors that management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. A number of these factors include, among others, economic conditions, credit markets, foreign currency, commodity cost volatility and consumer spending and confidence, all of which have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual amounts could differ significantly from those estimated at the time the consolidated financial statements are prepared. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash and Cash Equivalents – We consider all highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents.

Restricted Cash – We have a total of $393 as of December 31, 2013 that serves as collateral backing certain bank guarantees and is therefore restricted. This money is invested in time deposits.

Receivables – Credit is granted to our customers in the normal course of business. Receivables are recorded at original carrying value less reserves for estimated uncollectible accounts and sales returns. To assess the collectability of these receivables, we perform ongoing credit evaluations of our customers’ financial condition. Through these evaluations, we may become aware of a situation where a customer may not be able to meet its financial obligations due to deterioration of its financial viability, credit ratings or bankruptcy. The reserve requirements are based on the best facts available to us and are reevaluated and adjusted as additional information becomes available. Our reserves are also based on amounts determined by using percentages applied to trade receivables. These percentages are determined by a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. An account is considered past-due or delinquent when it has not been paid within the contractual terms. Uncollectible accounts are written off against the reserves when it is deemed that a customer account is uncollectible.

Inventories – Inventories are valued at the lower of cost or market. Cost is determined on a first-in, first-out (“FIFO”) basis except for Inventories in North America and Japan which are determined on a last-in, first-out (“LIFO”) basis.

Property, Plant and Equipment – Property, plant and equipment is carried at cost. Additions and improvements that extend the lives of the assets are capitalized while expenditures for repairs and maintenance are expensed as incurred. We generally depreciate buildings and improvements by the straight-line method over a life of 30 years . Other property, plant and equipment are generally depreciated using the straight-line method based on lives of 3 years to 15 years.

Goodwill – Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. We analyze Goodwill on an annual basis as of year end and when an event occurs or circumstances change that may reduce the fair value of one of our reporting units below its carrying amount. A goodwill impairment occurs if the carrying amount of a reporting unit’s goodwill exceeds its fair value. In assessing the recoverability of Goodwill, we use an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.

Intangible Assets – Intangible Assets consist of definite lived customer lists, service contracts, an acquired trade name and technology. Intangible Assets with a definite life are amortized on a straight-line basis.

Impairment of Long-lived Assets – We periodically review our intangible and long-lived assets for impairment and assess whether events or circumstances indicate that the carrying amount of the assets may not be recoverable. We generally deem an asset group to be impaired if an estimate of undiscounted future operating cash flows is less than its carrying amount. If impaired, an impairment loss is recognized based on the excess of the carrying amount of the individual asset group over its fair value.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except shares and per share data)

Purchases of Common Stock – We repurchase our Common Stock under a 2011 and a 2012 repurchase program authorized by our Board of Directors. These programs allow us to repurchase up to 2,000,000 shares of our Common Stock. Upon repurchase, the par value is charged to Common Stock and the remaining purchase price is charged to Additional Paid-in Capital. If the amount of the remaining purchase price causes the Additional Paid-in Capital account to be in a debit position, this amount is then reclassified to Retained Earnings. Common Stock repurchased is included in shares authorized but is not included in shares outstanding.

Warranty – We record a liability for estimated warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. In the event we determine that our current or future product repair and replacement costs exceed our estimates, an adjustment to these reserves would be charged to earnings in the period such determination is made. Warranty terms on machines range from one to four years.

Environmental – We record a liability for environmental clean-up on an undiscounted basis when a loss is probable and can be reasonably estimated.

Pension and Profit Sharing Plans – We have pension and/or profit sharing plans covering substantially all of our employees. Pension plan costs are accrued based on actuarial estimates with the required pension cost funded annually, as needed. No new participants have entered the pension plan since 2000.

Postretirement Benefits – We accrue and recognize the cost of retiree health benefits over the employees’ period of service based on actuarial estimates. Benefits are only available for U.S. employees hired before January 1, 1999.

Derivative Financial Instruments – 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. We periodically enter into various contracts, principally forward exchange contracts, to protect the value of certain of our foreign currency-denominated assets and liabilities (principally the Euro, Australian and Canadian dollars, British pound, Japanese yen, Chinese yuan and Brazilian real). We have elected not to apply hedge accounting treatment to these contracts as our contracts are for a short duration. These contracts are marked-to-market with the related asset or liability recorded in Other Current Assets or Other Current Liabilities, as applicable. The gains and losses on these contracts generally approximate changes in the value of the related assets and liabilities. Gains or losses on forward foreign exchange contracts to economically hedge foreign currency-denominated net assets and liabilities are recognized in Other Income (Expense) under Net Foreign Currency Transaction (Losses) Gains within the Consolidated Statements of Earnings.

Revenue Recognition – We recognize revenue when persuasive evidence of an arrangement exists, title and risk of ownership have passed to the customer, the sales price is fixed or determinable and collectibility is reasonably assured. Generally, these criteria are met at the time the product is shipped. Provisions for estimated returns, rebates and discounts are provided for at the time the related revenue is recognized. Freight revenue billed to customers is included in Net Sales and the related shipping expense is included in Cost of Sales. Service revenue is recognized in the period the service is performed or ratably over the period of the related service contract.

Customers may obtain financing through third-party leasing companies to assist in their acquisition of our equipment products. Certain lease transactions classified as operating leases contain retained ownership provisions or guarantees, which results in recognition of revenue over the lease term. As a result, we defer the sale of these transactions and record the sales proceeds as collateralized borrowings or deferred revenue. The underlying equipment relating to operating leases is depreciated on a straight-line basis, not to exceed the equipment’s estimated useful life.

Revenues from contracts with multiple element arrangements are recognized as each element is earned. We offer service contracts in conjunction with equipment sales in addition to selling equipment and service contracts separately. Sales proceeds related to service contracts are deferred if the proceeds are received in advance of the service and recognized ratably over the contract period.

Share-based Compensation – We account for employee share-based compensation using the fair value based method. Our share-based compensation plans are more fully described in Note 15 of the Consolidated Financial Statements.

Research and Development – Research and development costs are expensed as incurred.

Advertising Costs –We advertise products, technologies and solutions to customers and prospective customers through a variety of marketing campaign and promotional efforts. These efforts include tradeshows, online advertising, e-mail marketing, mailings, sponsorships and telemarketing. Advertising costs are expensed as incurred. In 2013, 2012 and 2011 such activities amounted to $6,412, $6,466 and $6,728, respectively.

Income Taxes – Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the book and tax bases of existing assets and liabilities. A valuation allowance is provided when, in management’s judgment, it is more likely than not that some portion or all of the deferred tax asset will not be realized. We have established contingent tax liabilities using management’s best judgment. We follow guidance provided by Accounting Standards Codification ("ASC") 740, Income Taxes, regarding uncertainty in income taxes, to record these contingent tax liabilities (refer to Note 14 of the Consolidated Financial Statements for additional information). We adjust these liabilities as facts and circumstances change. Interest Expense is recognized in the first period the interest would begin accruing. Penalties are recognized in the period we claim or expect to claim the position in our tax return. Interest and penalties expenses are classified as an income tax expense.

Sales Tax –Sales taxes collected from customers and remitted to governmental authorities are presented on a net basis.

Earnings per Share – Basic earnings per share is computed by dividing Net Earnings by the Weighted Average Shares Outstanding during the period. Diluted earnings per share assume conversion of potentially dilutive stock options and restricted share awards. Performance-based shares are included in the calculation of diluted earnings per share in the quarter in which the performance targets have been achieved.

2. Newly Adopted Accounting Pronouncements

Offsetting Assets and Liabilities Disclosures

In December 2011, the Financial Accounting Standards Board (“FASB”) issued updated accounting guidance on disclosures about offsetting assets and liabilities. This update adds certain additional disclosure requirements about financial instruments and derivative instruments that are subject to netting arrangements. The new disclosures are required for interim and annual reporting periods beginning on or after January 1, 2013. This guidance did not have a material impact on our results of operations or financial position.

Comprehensive Income

In February 2013, the FASB issued new disclosure requirements for items reclassified out of accumulated other comprehensive income. The requirements do not change the existing accounting and reporting for net income or other comprehensive income. The requirements are effective for annual reporting periods beginning after December 15, 2012. The requirements did not impact our results of operations or financial position.

3. Management Actions

Q4 2013 Action- During the fourth quarter of 2013, we implemented a restructuring action. A pre-tax charge of $1,577 was recognized in the fourth quarter as a result of this action. The pre-tax charge consisted primarily of severance and was included within Selling and Administrative Expense in the Consolidated Statements of Earnings.

A reconciliation of the beginning and ending liability balances is as follows:

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 $2,963 as of December 31, 2013, 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 in our Profit from Operations in the Consolidated Statements of Earnings for the year ended December 31, 2012.

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 19, M&F is a related party to Tennant. 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 Tennant is not the primary beneficiary of this VIE. The only financing Tennant has 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.

The assets and liabilities transferred under the Share Purchase Agreement on the date of sale were as follows:

Accounts Receivable	$	4,398
Inventories	4,271
Other Current Assets	87
Current Assets	8,756
Property, Plant and Equipment, Net	170

7. Goodwill and Intangible Assets

For purposes of performing our goodwill impairment analysis, we have identified our reporting units as North America; Latin America; Europe, Middle East, Africa (“EMEA”) and Asia Pacific. As of December 31, 2013, 2012 and 2011, we performed an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Based on our analysis of qualitative factors, we determined that it was not necessary to perform the two-step goodwill impairment test for any of our reporting units.

The changes in the carrying amount of Goodwill are as follows:

	Goodwill		Accumulated Impairment Losses			Total
Balance as of December 31, 2011	$	66,523	$	(46,220	)	$	20,303
Foreign currency fluctuations	2,062		(2,648		)	(586		)

Foreign currency fluctuations	321		(1,109		)	(788		)
Balance as of December 31, 2013	$	68,906	$	(49,977	)	$	18,929

The balances of acquired Intangible Assets, excluding Goodwill, as of December 31, are as follows:

	Customer Lists and Service Contracts			Trade Name			Technology			Total
Balance as of December 31, 2013
Original cost	$	23,763		$	4,836		$	7,347		$	35,946

Carrying amount	$	13,910		$	3,092		$	4,391		$	21,393
Weighted-average original life (in years)	15			14			13

During the second quarter of 2011, we impaired customer lists and technology Intangible Assets totaling $1,805 related to the obsolescence of the two Hofmans outdoor city cleaning products in Europe. This impairment charge is included within Selling and Administrative Expense in the 2011 Consolidated Statement of Earnings.

Amortization expense on Intangible Assets was $2,560, $2,800 and $3,330 for the years ended December 31, 2013, 2012 and 2011, respectively.

Estimated aggregate amortization expense based on the current carrying amount of amortizable Intangible Assets for each of the five succeeding years is as follows:

2014	$	2,387
2015	2,204
2016	1,871
2017	1,768
2018	1,761

There were $10,000 outstanding borrowings under our JPMorgan facility, $20,000 outstanding borrowings under our Prudential facility and $1,500 outstanding under the facility with HSBC Shanghai as of December 31, 2013. In addition, we had stand alone letters of credit of approximately $2,060 outstanding and bank guarantees in the amount of approximately $501. Commitment fees on unused lines of credit for the year ended December 31, 2013 were $307.

Our most restrictive covenants are part of our Credit Agreement with JPMorgan, which are the same covenants in our Shelf Agreement with Prudential described below, and require us to maintain an indebtedness to EBITDA ratio of not greater than 3.00 to 1 and to maintain an EBITDA to interest expense ratio of no less than 3.50 to 1 as of the end of each quarter. As of December 31, 2013, our indebtedness to EBITDA ratio was 0.41 to 1 and our EBITDA to interest expense ratio was 48.00 to 1.

Credit Facilities

JPMorgan Chase Bank, National Association

On April 25, 2013, we entered into Amendment No. 1 to our 2011 Credit Agreement which amends the Credit Agreement, dated as of May 5, 2011, with JPMorgan Chase Bank, N. A. (“JPMorgan”), as administrative agent and collateral agent, U.S. Bank National Association, as syndication agent, Wells Fargo Bank, National Association, and RBS Citizens, N.A., as co-documentation agents, and the Lenders (including JPMorgan) from time to time party thereto (the “2011 Credit Agreement”). Under the original terms, the 2011 Credit Agreement provides us and certain of our foreign subsidiaries access to a senior unsecured credit facility until May 5, 2016, in the amount of $125,000, with an option to expand by up to $62,500 to a total of $187,500. Borrowings may be denominated in U.S. Dollars or certain other currencies. The 2011 Credit Agreement contains a $100,000 sublimit on borrowings by foreign subsidiaries.

Under the original terms of the 2011 Credit Agreement, the fee for committed funds ranges from an annual rate of 0.25% to 0.40%, depending on our leverage ratio. Eurocurrency borrowings under the 2011 Credit Agreement bear interest at a rate per annum equal to adjusted LIBOR plus an additional spread of 1.50% to 2.10%, depending on our leverage ratio. Alternate Base Rate (“ABR”) borrowings bear interest at a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.50% to 1.10%, depending on our leverage ratio.

Effective April 25, 2013, Amendment No. 1 to the 2011 Credit Agreement principally provides the following changes to the 2011 Credit Agreement:

• extends the maturity date of the 2011 Credit Agreement to March 1, 2018;

• changes the fees for committed funds under the 2011 Credit Agreement to an annual rate ranging from 0.20% to 0.35%, depending on our leverage ratio;

• changes the per annum interest rate on Eurocurrency borrowings to adjusted LIBOR plus an additional spread of 1.30% to 1.90%, depending on our leverage ratio;

• changes the ABR rate at which borrowings bear interest to a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.30% to 0.90%, depending on our leverage ratio; and

• changes related to new or recently revised financial regulations.

The 2011 Credit Agreement gives the Lenders a pledge of 65% of the stock of certain first tier foreign subsidiaries. The obligations under the 2011 Credit Agreement are also guaranteed by certain of our first tier domestic subsidiaries.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except shares and per share data)

The 2011 Credit Agreement contains customary representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and merge or consolidate with another entity. Further, the 2011 Credit Agreement contains the following covenants:

• a covenant requiring us to maintain an indebtedness to EBITDA ratio as of the end of each quarter of not greater than 3.00 to 1;

• a covenant requiring us to maintain an EBITDA to interest expense ratio as of the end of each quarter of no less than 3.50 to 1;

• a covenant restricting us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and

• a covenant restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

As of December 31, 2013 we were in compliance with all covenants under the Credit Agreement. There was $10,000 in outstanding borrowings under this facility at December 31, 2013, with a weighted average interest rate of 1.47%.

Prudential Investment Management, Inc.

On July 29, 2009, we entered into a Private Shelf Agreement (the “Shelf Agreement”) with Prudential Investment Management, Inc. (“Prudential”) and Prudential affiliates from time to time party thereto. The Shelf Agreement provides us and our subsidiaries access to an uncommitted, senior secured, maximum aggregate principal amount of $80,000 of debt capital. The Shelf Agreement contains representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and to merge or consolidate with another entity. The Shelf Agreement limits the payment of dividends or repurchases of stock to an amount ranging from $12,000 to $40,000 based on our leverage ratio after giving effect to such payments.

On May 5, 2011, we entered into Amendment No. 1 to our Private Shelf Agreement (the “Amendment”).

The Amendment principally provides the following changes to the Shelf Agreement:

• elimination of the security interest in our personal property and subsidiaries;

• an amendment to the maximum leverage ratio to not greater than 3.00 to 1 for any period ending on or after March 31, 2011;

• an amendment to our restriction regarding the payment of dividends or repurchase of stock to restrict us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and

• an amendment to Permitted Acquisitions restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

On July 24, 2012, we entered into Amendment No. 2 to our Private Shelf Agreement (“Amendment No. 2”), which amends the Shelf Agreement. The principal change effected by Amendment No. 2 is an extension of the Issuance Period for Shelf Notes under the Shelf Agreement. The Issuance Period now expires on July 24, 2015.

As of December 31, 2013, there was $20,000 in outstanding borrowings under this facility; the $10,000 Series A notes issued in March 2011 with a fixed interest rate of 4.00% and a 7 year term serially maturing from 2014 to 2018; and the $10,000 Series B notes issued in June 2011 with a fixed interest rate of 4.10% and a 10 year term serially maturing from 2015 to 2021. We were in compliance with all covenants of the Shelf Agreement as of December 31, 2013.

The Royal Bank of Scotland Citizens, N.A.

On September 14, 2010, we entered into an overdraft facility with The Royal Bank of Scotland Citizens, N.A. in the amount of 2,000 Euros or approximately $2,757. There was no balance outstanding on this facility as of December 31, 2013.

HSBC Bank (China) Company Limited, Shanghai Branch

On June 20, 2012, we entered into a banking facility with the HSBC Bank (China) Company Limited, Shanghai Branch in the amount of $5,000. There was $1,500 in outstanding borrowings on this facility as of December 31, 2013, with a fixed interest rate of 5.1%.

Notes Payable

On May 31, 2011, we incurred $1,500 in debt related to installment payments due to the former owners of Water Star in connection with our acquisition of Water Star, of which none remains outstanding as of December 31, 2013.

Collateralized Borrowings

Collateralized borrowings represent deferred sales proceeds on certain leasing transactions with third-party leasing companies. These transactions are accounted for as borrowings, with the related assets capitalized as property, plant and equipment and depreciated straight-line over the lease term.

Capital Lease Obligations

Capital lease obligations outstanding are primarily related to sale-leaseback transactions with third-party leasing companies whereby we sell our manufactured equipment to the leasing company and lease it back. The equipment covered by these leases is rented to our customers over the lease term.

10. Fair Value Measurements

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 December 31, 2013 is as follows:

	Fair Value		Level 1		Level 2		Level 3
Assets:
Foreign currency forward exchange contracts	$	16	$	—	$	16	$	—
Total Assets	$	16	$	—	$	16	$	—
Liabilities:
Foreign currency forward exchange contracts	$	109	$	—	$	109	$	—
Total Liabilities	$	109	$	—	$	109	$	—

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 to economically hedge foreign currency-denominated assets and liabilities are recognized in Other Current Assets and Other Current Liabilities within the Consolidated Balance Sheets and are recognized in Other Income (Expense) under Net Foreign Currency Transaction (Losses) Gains within the Consolidated Statements of Earnings. As of December 31, 2013 the fair value of such contracts outstanding was an asset of $16 and a liability of $109. As of December 31, 2012 the fair value of such contracts outstanding was an asset of $388 and a liability of $404. We recognized a net gain of $1,068 during 2013, a net gain of $1,026 during 2012 and a net loss of $1,444 during 2011. At December 31, 2013 and 2012, the notional amounts of foreign currency forward exchange contracts outstanding were $30,280 and $42,475, respectively.

The carrying amounts reported in the Consolidated Balance Sheets for Cash and Cash Equivalents, Restricted Cash, Receivables, Other Current Assets, Short-Term Debt, Accounts Payable and Other Current Liabilities approximate fair value due to their short-term nature.

The fair market 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.

11. Retirement Benefit Plans

Substantially all U.S. employees are covered by various retirement benefit plans, including defined benefit pension plans, post-retirement medical plans and defined contribution savings plans. Retirement benefits for eligible employees in foreign locations are funded principally through defined benefit plans, annuity or government programs. The total cost of benefits for our plans was $11,766, $11,192 and $11,271 in 2013, 2012 and 2011, respectively.

We have a qualified, funded defined benefit retirement plan (the “U.S. Pension Plan”) in the U.S. covering certain current and retired employees. Plan benefits are based on the years of service and compensation during the highest five consecutive years of service in the final ten years of employment. No new participants have entered the plan since 2000. The plan has 442 participants including 90 active employees as of December 31, 2013.

We have a U.S. postretirement medical benefit plan (the “U.S. Retiree Plan”) to provide certain healthcare benefits for U.S. employees hired before January 1, 1999. Eligibility for those benefits is based upon a combination of years of service with Tennant and age upon retirement.

Our defined contribution savings plan (“401(k)”) covers substantially all U.S. employees. Under this plan, we match up to 3% of the employee’s annual compensation in cash to be invested per their election. We also make a profit sharing contribution to the 401(k) plan for employees with more than one year of service in accordance with our Profit Sharing Plan. This contribution is based upon our financial performance and can be funded in the form of Tennant stock, cash or a combination of both. Expenses for the 401(k) plan were $6,423, $6,226 and $6,864 during 2013, 2012 and 2011, respectively.

We have a U.S. nonqualified supplemental benefit plan (the “U.S. Nonqualified Plan”) to provide additional retirement benefits for certain employees whose benefits under our 401(k) plan or U.S. Pension Plan are limited by either the Employee Retirement Income Security Act or the Internal Revenue Code.

We also have defined pension benefit plans in the United Kingdom and Germany (the “U.K. Pension Plan” and the “German Pension Plan”). The U.K. Pension Plan and German Pension Plan cover certain current and retired employees and both plans are closed to new participants.

On March 23, 2010, the Patient Protection and Affordable Care Act (the “PPACA”) was signed into law, and, on March 30, 2010, the Health Care and Education Reconciliation Act of 2010 (the “HCERA” and, together with PPACA, the “Acts”), which makes various amendments to certain aspects of the PPACA, was signed into law. The Acts effectively change the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that provide prescription drug benefits that are at least actuarially equivalent to the corresponding benefits provided under Medicare Part D. Under the Acts, an employer’s income tax deduction for the costs of providing Medicare Part D-equivalent prescription drug benefits to retirees will be reduced by the amount of the federal subsidy beginning in 2013. Under U.S. GAAP, any impact from a change in tax law must be recognized in earnings in the period enacted regardless of the effective date. The Acts did not have a material impact on our financial position or results of operations.

We expect to contribute approximately $149 to our U.S. Nonqualified Plan, $919 to our U.S. Retiree Plan, $237 to our U.K. Pension Plan and $41 to our German Pension Plan in 2014. No contributions to the U.S. Pension Plan are expected to be required during 2014. There were no contributions made to the U.S. Pension Plan during 2013. During 2012, we made a $15,000 discretionary contribution to the U.S. Pension Plan in addition to the minimum funding requirements for 2011 and 2012.

Weighted-average asset allocations by asset category of the U.S. and U.K. Pension Plans as of December 31, 2013 are as follows:

Asset Category	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Estimates of the fair value of U.S. and U.K Pension Plan assets are based on the framework established in the accounting guidance for fair value measurements. A brief description of the three levels can be found in Note 10. Equity Securities and Mutual Funds traded in active markets are classified as Level 1. The Investment Account held by Pension Plan invests in insurance contracts for purposes of funding the U.K. Pension Plan and are classified as Level 3. The fair value of the Investment Account are the cash surrender values as determined by the provider which are the amounts the plan would receive if the contracts were cashed out at year end. The underlying assets held by these contracts are primarily invested in assets traded in active markets.

A reconciliation of the beginning and ending balances of the Level 3 investments of our U.K. Pension Plan during the years ended are as follows:

	2013		2012
Fair value at beginning of year	$	8,855	$	7,738

The primary objective of our U.S. and U.K. Pension Plans is to meet retirement income commitments to plan participants at a reasonable cost to us and to maintain a sound actuarially funded status. This objective is accomplished through growth of capital and safety of funds invested. The pension plans' assets are invested in securities to achieve growth of capital over inflation through appreciation and accumulation and reinvestment of dividend and interest income. Investments are diversified to control risk. The target allocation for the U.S. Pension Plan is 60% equity and 40% debt securities. Equity securities within the U.S. Pension Plan do not include any direct investments in Tennant Company Common Stock. The U.K. Pension Plan is invested in insurance contracts with underlying investments primarily in equity and fixed income securities. Our German Pension Plan is unfunded, which is customary in that country.

Weighted-average assumptions used to determine benefit obligations as of December 31, are as follows:

The discount rate is used to discount future benefit obligations back to today’s dollars. Our discount rates were determined based on high-quality fixed income investments. The resulting discount rates are consistent with the duration of plan liabilities. The Citigroup Above Median Spot Rate is used in determining the discount rate for the U.S. Plans. The expected return on assets assumption on the investment portfolios for the pension plans is based on the long-term expected returns for the investment mix of assets currently in the portfolio. Management uses historic return trends of the asset portfolio combined with recent market conditions to estimate the future rate of return.

12. Shareholders' Equity

Authorized Shares

We are authorized to issue an aggregate of 61,000,000 shares; 60,000,000 are designated as Common Stock, having a par value of $0.375 per share, and 1,000,000 are designated as Preferred Stock, having a par value of $0.02 per share. The Board of Directors is authorized to establish one or more series of preferred stock, setting forth the designation of each such series, and fixing the relative rights and preferences of each such series.

Purchase Rights

On November 10, 2006, the Board of Directors approved a Rights Agreement and declared a dividend of one preferred share purchase right for each outstanding share of Common Stock. Each right entitles the registered holder to purchase from us one one-hundredth of a Series A Junior Participating Preferred Share of the par value of $0.02 per share at a price of $100 per one hundredth of a Preferred Share, subject to adjustment. The rights are not exercisable or transferable apart from the Common Stock until the earlier of: (i) the close of business on the fifteenth day following a public announcement that a person or group of affiliated or associated persons has become an “Acquiring Person” (i.e., has become, subject to certain exceptions, including for stock ownership by employee benefit plans, the beneficial owner of 20% or more of the outstanding Common Stock), or (ii) the close of business on the fifteenth day following the first public announcement of a tender offer or exchange offer the consummation of which would result in a person or group of affiliated or associated persons becoming, subject to certain exceptions, the beneficial owner of 20% or more of the outstanding Common Stock (or such later date as may be determined by our Board of Directors prior to a person or group of affiliated or associated persons becoming an Acquiring Person). After a person or group becomes an Acquiring Person, each holder of a Right (other than an Acquiring Person) will be able to exercise the right at the current exercise price of the Right and receive the number of shares of Common Stock having a market value of two times the exercise price of the right, or, depending upon the circumstances in which the rights became exercisable, the number of common shares of the Acquiring Person having a market value of two times the exercise price of the right. At no time do the rights have any voting power. We may redeem the rights for $0.001 per right at any time prior to a person or group acquiring 20% or more of the Common Stock. Under certain circumstances, the Board of Directors may exchange the rights for our Common Stock or reduce the 20% thresholds to not less than 10%. The rights will expire on December 26, 2016, unless extended or earlier redeemed or exchanged by us.

13. Commitments and Contingencies

We lease office and warehouse facilities, vehicles and office equipment under operating lease agreements, which include both monthly and longer-term arrangements. Leases with initial terms of one year or more expire at various dates through 2020 and generally provide for extension options. Rent expense under the leasing agreements (exclusive of real estate taxes, insurance and other expenses payable under the leases) amounted to $17,873, $17,524 and $17,375 in 2013, 2012 and 2011, respectively.

The minimum rentals for aggregate lease commitments as of December 31, 2013, were as follows:

2014	$	8,398
2015	5,378
2016	3,129
2017	1,892
2018	778
Thereafter	311
Total	$	19,886

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. The aggregate residual value at lease expiration of those leases is $11,741, of which we have guaranteed $7,659. As of December 31, 2013, we have recorded a liability for the estimated end-of-term loss related to this residual value guarantee of $398 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 first quarter of 2013, we renewed our lease for our Louisville facility. This lease has a five year term with a total commitment of $4,710.

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 $1,306 remains outstanding as of December 31, 2013.

In the ordinary course of business, we may become liable with respect to pending and threatened litigation, tax, environmental and other matters. While the ultimate results of current claims, investigations and lawsuits involving us are unknown at this time, we do not expect that these matters will have a material adverse effect on our consolidated financial position or results of operations. Legal costs associated with such matters are expensed as incurred.

Total Income Tax Expense	$	19,647		$	18,306		$	16,017

U.S. income taxes have not been provided on approximately $23,596 of undistributed earnings of non-U.S. subsidiaries. We do not have any plans to repatriate the undistributed earnings. Any repatriation from foreign subsidiaries that would result in incremental U.S. taxation is not being considered. It is management’s belief that reinvesting these earnings outside the U.S. is the most efficient use of capital.

We have Dutch and German tax loss carryforwards of approximately $18,046 and $15,674, respectively. If unutilized, the Dutch tax loss carryforward will expire after 9 years. The German tax loss carryforward has no expiration date. Because of the uncertainty regarding realization of the Dutch tax loss carryforward, a valuation allowance was established. This valuation allowance increased in 2013 due to results of operations.

We have U.S. foreign tax credit carryforwards of approximately $3,157. If unutilized, foreign tax credit carryforwards will expire in 2020. Based upon evaluation, as of December 31, 2013, no valuation allowance has been recorded. We have Dutch foreign tax credit carryforwards of $922. Because of the uncertainty regarding utilization of the Dutch foreign tax credit carryforward, a valuation allowance was established.

A valuation allowance for the remaining deferred tax assets is not required since it is more likely than not that they will be realized through carryback to taxable income in prior years, future reversals of existing taxable temporary differences and future taxable income.

Our effective income tax rate varied from the U.S. federal statutory tax rate for the three years ended December 31, as follows:

	2013		2012		2011
Tax at statutory rate	35.0	%	35.0	%	35.0	%
Increases (decreases) in the tax rate from:
State and local taxes, net of federal benefit	1.7		1.0		2.0
Effect of foreign operations	(3.3	)	(6.2	)	0.5
Effect of changes in valuation allowances	3.7		2.3		—
Domestic production activities deduction	(1.6	)	(1.5	)	(1.6	)
Other, net	(2.7	)	—		(3.0	)
Effective income tax rate	32.8	%	30.6	%	32.9	%

Deferred tax assets and liabilities were comprised of the following as of December 31:

Deferred Tax Assets:
Inventories, principally due to additional costs inventoried for tax purposes and changes in inventory reserves	$	—		$	28		$	426

Total Net Deferred Tax Assets	$	27,281		$	33,766		$	38,442
Deferred Tax Liabilities:
Inventories, principally due to changes in inventory reserves	$	306		$	—		$	—
Property, Plant and Equipment, principally due to differences in depreciation and related gains	7,446			7,945			9,167
Goodwill and Intangible Assets	6,253			6,818			7,093
Total Deferred Tax Liabilities	$	14,005		$	14,763		$	16,260
Net Deferred Tax Assets	$	13,276		$	19,003		$	22,182

The valuation allowance at December 31, 2013 principally applies to Dutch tax loss and tax credit carryforwards that, in the opinion of management, are more likely than not to expire unutilized. However, to the extent that tax benefits related to these carryforwards are realized in the future, the reduction in the valuation allowance will reduce income tax expense.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2013			2012
Balance at January 1,	$	3,480		$	3,424
Increases as a result of tax positions taken during a prior period	155			—
Increases as a result of tax positions taken during the current year	508			611
Reductions as a result of a lapse of the applicable statute of limitations	(295		)	(447		)
Decreases as a result of foreign currency fluctuations	(188		)	(108		)
Balance at December 31,	$	3,660		$	3,480

Included in the balance of unrecognized tax benefits at December 31, 2013 and 2012 are potential benefits of $3,384 and $3,259, respectively, that if recognized, would affect the effective tax rate from continuing operations.

We recognize potential accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. In addition to the liability of $3,660 and $3,480 for unrecognized tax benefits as of December 31, 2013 and 2012 was approximately $525 and $462, respectively, for accrued interest and penalties. To the extent interest and penalties are not assessed with respect to uncertain tax positions, the amounts accrued will be revised and reflected as an adjustment to income tax expense.

We 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 are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2007 to 2011. Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.

We do not anticipate that total unrecognized tax benefits will change significantly within the next 12 months.

15. Share-Based Compensation

We have five plans under which we have awarded share-based compensation grants: The 1995 Stock Incentive Plan (“1995 Plan”) and 1999 Amended and Restated Stock Incentive Plan (“1999 Plan”), which provided for share-based compensation grants to our executives and key employees, the 1997 Non-Employee Directors Option Plan (“1997 Plan”), which provided for stock option grants to our non-employee Directors, the 2007 Stock Incentive Plan (“2007 Plan”) and the Amended and Restated 2010 Stock Incentive Plan, as Amended (“2010 Plan”), which were adopted as a continuing step toward aggregating our equity compensation programs to reduce the complexity of our equity compensation programs.

The 1995 and 1997 Plans were terminated in 2006 and all remaining shares were transferred to the 1999 Plan as approved by the shareholders in 2006. Awards granted under the 1995 and 1997 Plans prior to 2006 that remain outstanding continue to be governed by the respective plan under which the grant was made. Upon approval of the 1999 Plan in 2006, we ceased making grants of future awards under these plans and subsequent grants of future awards were made from the 1999 Plan and governed by its terms.

The 2007 Plan terminated our rights to grant awards under the 1999 Plan except that the 1999 Plan will remain available for grants of reload options upon exercise of previously granted options with one-time reload features. We have not granted options with reload features since March 1, 2004. Awards previously granted under the 1999 Plan remain outstanding and continue to be governed by the terms of that plan.

The 2010 Plan, originally approved by our shareholders on April 28, 2010 and amended and restated by our shareholders on April 25, 2012, terminated our rights to grant awards under the 2007 Plan; however, any awards granted under the 2007 or 2010 Plans that do not result in the issuance of shares of Common Stock may again be used for an award under the 2010 Plan. The 2010 Plan was amended and restated by our shareholders on April 24, 2013, increasing the number of shares available under the amended 2010 Plan from 1,500,000 shares to 2,600,000 shares.

As of December 31, 2013, there were 499,248 shares reserved for issuance under the 1995 Plan, the 1997 Plan, the 1999 Plan and the 2007 Plan for outstanding compensation awards and 1,643,264 shares were available for issuance under the 2010 Plan for current and future equity awards. The Compensation Committee of the Board of Directors determines the number of shares awarded and the grant date, subject to the terms of our equity award policy.

We recognized total Share-Based Compensation Expense of $6,116, $9,092 and $5,407, respectively, during the years ended 2013, 2012 and 2011. The total excess tax benefit recognized for share-based compensation arrangements during the years ended 2013, 2012 and 2011 was $5,178, $2,047 and $1,266, respectively.

Stock Option Awards

We determined the fair value of our stock option awards using the Black-Scholes valuation model that uses the assumptions noted in the table below. The expected life selected for stock options granted during the year represents the period of time that the stock options are expected to be outstanding based on historical data of stock option holder exercise and termination behavior of similar grants. The risk-free interest rate for periods within the contractual life of the stock option is based on the U.S. Treasury rate over the expected life at the time of grant. Expected volatilities are based upon historical volatility of our stock over a period equal to the expected life of each stock option grant. Dividend yield is estimated over the expected life based on our dividend policy and historical dividends paid. We use historical data to estimate pre-vesting forfeiture rates and revise those estimates in subsequent periods if actual forfeitures differ from those estimates.

The following table illustrates the valuation assumptions used for the 2013, 2012 and 2011 grants:

	2013	2012	2011
Expected volatility	51%	51 - 52%	49 - 50%
Weighted-average expected volatility	51%	52%	49%
Expected dividend yield	1.6%	1.6 - 1.7%	1.7 - 1.8%
Weighted-average expected dividend yield	1.6%	1.7%	1.8%
Expected term, in years	6	0.2 - 6	6
Risk-free interest rate	0.9 - 1.1%	0.1 - 1.1%	1.3 - 2.5%

Employee stock option awards prior to 2005 include a reload feature for options granted to key employees. This feature allows employees to exercise options through a stock-for-stock exercise using mature shares, and employees are granted a new stock option (reload option) equal to the number of shares of Common Stock used to satisfy both the exercise price of the option and the minimum tax withholding requirements. The reload options granted have an exercise price equal to the fair market value of the Common Stock on the grant date. Stock options granted in conjunction with reloads vest immediately and have a term equal to the remaining life of the initial grant. Compensation expense is fully recognized for reload stock options as of the reload date.

Beginning in 2004, new stock option awards granted vest one-third each year over a three year period and have a ten year contractual term. These grants do not contain a reload feature. Compensation expense equal to the grant date fair value is recognized for these awards over the vesting period.

In addition to stock options, we also occasionally grant cash-settled stock appreciation rights (“SARs”) to employees in certain foreign locations. There were no outstanding SARs as of December 31, 2013 and no SARs were granted during 2013, 2012 or 2011.

Outstanding at end of year	877,322		$	30.42
Exercisable at end of year	601,747		$	23.89

The weighted-average grant date fair value of stock options granted during the years ended December 31, 2013, 2012 and 2011 was $19.62, $16.60 and $16.67, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2013, 2012 and 2011 was $15,641, $5,826 and $5,600, respectively. The aggregate intrinsic value of options outstanding and exercisable at December 31, 2013 was $32,805 and $26,427, respectively. The weighted-average remaining contractual life for options outstanding and exercisable as of December 31, 2013, was 7 years and 6 years, respectively. As of December 31, 2013, there was unrecognized compensation cost for nonvested options of $3,102 which is expected to be recognized over a weighted-average period of 1.6 years.

Restricted Share Awards

Restricted share awards for employees generally have a three year vesting period from the effective date of the grant. Restricted share awards to non-employee directors vest upon a change of control or upon termination of service as a director occurring at least six months after grant date of the award so long as termination is for one of the following reasons: death; disability; retirement in accordance with Tennant policy (e.g., age, term limits, etc.); resignation at request of Board (other than for gross misconduct); resignation following at least six months’ advance notice; failure to be renominated (unless due to unwillingness to serve) or reelected by shareholders; or removal by shareholders.

The following table summarizes the activity during the year ended December 31, 2013, for nonvested restricted share awards:

	Shares		Weighted-Average Grant Date Fair Value
Nonvested at beginning of year	142,354		$	33.40
Granted	34,508		48.04
Vested	(24,866	)	26.06
Forfeited	(1,053	)	40.02
Nonvested at end of year	150,943		$	37.89

The total fair value of shares vested during the year ended December 31, 2013, 2012 and 2011 was $643, $861 and $650, respectively. As of December 31, 2013, there was $1,993 of total unrecognized compensation cost related to nonvested shares which is expected to be recognized over a weighted-average period of 2.1 years.

Performance Share Awards

We grant performance share awards to key employees as a part of our long-term management compensation program. These awards are earned based upon achievement of certain financial performance targets over a three year period. We determine the fair value of these awards as of the date of grant and recognize the expense over a three year performance period. Performance shares are granted in restricted stock units. They are payable in stock and vest solely upon achievement of certain financial performance targets during this three year period.

The 2013 performance share award covers the three year performance period from the beginning of fiscal year 2013 to the end of fiscal year 2015. The 2012 performance share award covers the three year performance period from the beginning of fiscal year 2012 to the end of fiscal year 2014. The 2011 performance share award covered the three year performance period from the beginning of fiscal year 2011 to the end of fiscal year 2013.

The 2010 performance share award covered the three year performance period from the beginning of fiscal year 2010 to the end of fiscal year 2012. Performance shares were granted in restricted stock units. They were paid in cash and vested solely upon achievement of certain financial performance targets during this three year period.

In 2009, we granted a combination of stock options, restricted stock awards and restricted stock units payable in cash to key employees as part of our management compensation program and did not grant performance share awards. These stock options and restricted share awards vested over a three year period and did not contain a performance requirement.

Share-Based Liabilities

As of December 31, 2013 and 2012, we had $292 and $3,650 in total share-based liabilities recorded on our Consolidated Balance Sheets, respectively. During the years ended December 31, 2013, 2012 and 2011 we paid out $3,134, $2,212 and $506 related to 2010, 2009 and 2008 share-based liability awards, respectively.

16. Earnings Per Share

The computations of Basic and Diluted Earnings per Share for the years ended December 31, were as follows:

	2013		2012		2011
Numerator:
Net Earnings	$	40,231	$	41,584	$	32,713
Denominator:
Basic - Weighted Average Shares Outstanding	18,297,371		18,544,896		18,832,693
Effect of dilutive securities:
Employee stock options	536,082		557,120		527,735
Diluted - Weighted Average Shares Outstanding	18,833,453		19,102,016		19,360,428
Basic Earnings per Share	$	2.20	$	2.24	$	1.74
Diluted Earnings per Share	$	2.14	$	2.18	$	1.69

Options to purchase 132,803, 233,655 and 123,292 shares of Common Stock were outstanding during 2013, 2012 and 2011, respectively, but were not included in the computation of diluted earnings per share. These exclusions are made if the exercise prices of these options are greater than the average market price of our Common Stock for the period, if the number of shares we can repurchase under the treasury stock method exceeds the weighted shares outstanding in the options, or if we have a net loss, as the effects are anti-dilutive.

17. Segment Reporting

We are organized into four operating segments: North America; Latin America; Europe, Middle East, 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.

The following table presents Net Sales by operating segment for the years ended December 31:

Segment Reporting [Abstract]

Segment Reporting

17. Segment Reporting

We are organized into four operating segments: North America; Latin America; Europe, Middle East, 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.

The following table presents Net Sales by operating segment for the years ended December 31:

	2013		2012		2011
Net Sales:
Americas	$	514,544	$	491,661	$	481,426
Europe, Middle East, Africa	157,208		166,208		188,338
Asia Pacific	80,259		81,111		84,234
Total	$	752,011	$	738,980	$	753,998

The following table presents long lived assets by operating segment as of December 31:

	2013		2012		2011
Long-lived assets:
Americas	$	106,409	$	100,662	$	100,843
Europe, Middle East, Africa	28,296		31,164		31,126
Asia Pacific	3,882		4,499		5,183
Total	$	138,587	$	136,325	$	137,152

Accounting policies of the operations in the various operating segments are the same as those described in Note 1 of the Consolidated Financial Statements. Net Sales are attributed to each operating segment based on the country from which the product is shipped and are net of intercompany sales. Information regarding sales to customers geographically located in the United States is provided in Item 1, Business - Segment and Geographic Area Financial Information. No single customer represents more than 10% of our consolidated Net Sales. Long-lived assets consist of Property, Plant and Equipment, Goodwill, Intangible Assets and certain other assets.

The following table presents revenues for groups of similar products and services for the years ended December 31:

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies [Abstract]

Significant Accounting Policies

1. Summary of Significant Accounting Policies

Nature of Operations – Our primary business is designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world. Our products include equipment for maintaining surfaces in industrial, commercial and outdoor environments; chemical-free and other sustainable cleaning technologies; and coatings for protecting, repairing and upgrading floors and other surfaces. We sell our products through our direct sales and service organization and a network of authorized distributors worldwide. Geographically, our customers are located in North America, Latin America, Europe, the Middle East, Africa and Asia Pacific.

Consolidation – The Consolidated Financial Statements include the accounts of Tennant Company and its subsidiaries. All intercompany transactions and balances have been eliminated. In these Notes to the Consolidated Financial Statements, Tennant Company is referred to as “Tennant,” “we,” “us,” or “our.”

Translation of Non-U.S. Currency – Foreign currency-denominated assets and liabilities have been translated to U.S. dollars at year-end exchange rates, while income and expense items are translated at average exchange rates prevailing during the year. Gains or losses resulting from translation are included as a separate component of Accumulated Other Comprehensive Loss. The balance of cumulative foreign currency translation adjustments recorded within Accumulated Other Comprehensive Loss as of December 31, 2013, 2012 and 2011 was a net loss of $21,991, $19,734 and $20,283, respectively. The majority of translation adjustments are not adjusted for income taxes as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Net Foreign Currency Transaction (Losses) Gains are included in Other Income (Expense).

Use of Estimates – In preparing the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), management must make decisions that impact the reported amounts of assets, liabilities, revenues, expenses and the related disclosures, including disclosures of contingent assets and liabilities. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. Estimates are used in determining, among other items, sales promotions and incentives accruals, inventory valuation, warranty reserves, allowance for doubtful accounts, pension and postretirement accruals, useful lives for intangible assets, and future cash flows associated with impairment testing for goodwill and other long-lived assets. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors that management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. A number of these factors include, among others, economic conditions, credit markets, foreign currency, commodity cost volatility and consumer spending and confidence, all of which have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual amounts could differ significantly from those estimated at the time the consolidated financial statements are prepared. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash and Cash Equivalents – We consider all highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents.

Restricted Cash – We have a total of $393 as of December 31, 2013 that serves as collateral backing certain bank guarantees and is therefore restricted. This money is invested in time deposits.

Receivables – Credit is granted to our customers in the normal course of business. Receivables are recorded at original carrying value less reserves for estimated uncollectible accounts and sales returns. To assess the collectability of these receivables, we perform ongoing credit evaluations of our customers’ financial condition. Through these evaluations, we may become aware of a situation where a customer may not be able to meet its financial obligations due to deterioration of its financial viability, credit ratings or bankruptcy. The reserve requirements are based on the best facts available to us and are reevaluated and adjusted as additional information becomes available. Our reserves are also based on amounts determined by using percentages applied to trade receivables. These percentages are determined by a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. An account is considered past-due or delinquent when it has not been paid within the contractual terms. Uncollectible accounts are written off against the reserves when it is deemed that a customer account is uncollectible.

Inventories – Inventories are valued at the lower of cost or market. Cost is determined on a first-in, first-out (“FIFO”) basis except for Inventories in North America and Japan which are determined on a last-in, first-out (“LIFO”) basis.

Property, Plant and Equipment – Property, plant and equipment is carried at cost. Additions and improvements that extend the lives of the assets are capitalized while expenditures for repairs and maintenance are expensed as incurred. We generally depreciate buildings and improvements by the straight-line method over a life of 30 years . Other property, plant and equipment are generally depreciated using the straight-line method based on lives of 3 years to 15 years.

Goodwill – Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. We analyze Goodwill on an annual basis as of year end and when an event occurs or circumstances change that may reduce the fair value of one of our reporting units below its carrying amount. A goodwill impairment occurs if the carrying amount of a reporting unit’s goodwill exceeds its fair value. In assessing the recoverability of Goodwill, we use an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.

Intangible Assets – Intangible Assets consist of definite lived customer lists, service contracts, an acquired trade name and technology. Intangible Assets with a definite life are amortized on a straight-line basis.

Impairment of Long-lived Assets – We periodically review our intangible and long-lived assets for impairment and assess whether events or circumstances indicate that the carrying amount of the assets may not be recoverable. We generally deem an asset group to be impaired if an estimate of undiscounted future operating cash flows is less than its carrying amount. If impaired, an impairment loss is recognized based on the excess of the carrying amount of the individual asset group over its fair value.

Purchases of Common Stock – We repurchase our Common Stock under a 2011 and a 2012 repurchase program authorized by our Board of Directors. These programs allow us to repurchase up to 2,000,000 shares of our Common Stock. Upon repurchase, the par value is charged to Common Stock and the remaining purchase price is charged to Additional Paid-in Capital. If the amount of the remaining purchase price causes the Additional Paid-in Capital account to be in a debit position, this amount is then reclassified to Retained Earnings. Common Stock repurchased is included in shares authorized but is not included in shares outstanding.

Warranty – We record a liability for estimated warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. In the event we determine that our current or future product repair and replacement costs exceed our estimates, an adjustment to these reserves would be charged to earnings in the period such determination is made. Warranty terms on machines range from one to four years.

Environmental – We record a liability for environmental clean-up on an undiscounted basis when a loss is probable and can be reasonably estimated.

Pension and Profit Sharing Plans – We have pension and/or profit sharing plans covering substantially all of our employees. Pension plan costs are accrued based on actuarial estimates with the required pension cost funded annually, as needed. No new participants have entered the pension plan since 2000.

Postretirement Benefits – We accrue and recognize the cost of retiree health benefits over the employees’ period of service based on actuarial estimates. Benefits are only available for U.S. employees hired before January 1, 1999.

Derivative Financial Instruments – 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. We periodically enter into various contracts, principally forward exchange contracts, to protect the value of certain of our foreign currency-denominated assets and liabilities (principally the Euro, Australian and Canadian dollars, British pound, Japanese yen, Chinese yuan and Brazilian real). We have elected not to apply hedge accounting treatment to these contracts as our contracts are for a short duration. These contracts are marked-to-market with the related asset or liability recorded in Other Current Assets or Other Current Liabilities, as applicable. The gains and losses on these contracts generally approximate changes in the value of the related assets and liabilities. Gains or losses on forward foreign exchange contracts to economically hedge foreign currency-denominated net assets and liabilities are recognized in Other Income (Expense) under Net Foreign Currency Transaction (Losses) Gains within the Consolidated Statements of Earnings.

Revenue Recognition – We recognize revenue when persuasive evidence of an arrangement exists, title and risk of ownership have passed to the customer, the sales price is fixed or determinable and collectibility is reasonably assured. Generally, these criteria are met at the time the product is shipped. Provisions for estimated returns, rebates and discounts are provided for at the time the related revenue is recognized. Freight revenue billed to customers is included in Net Sales and the related shipping expense is included in Cost of Sales. Service revenue is recognized in the period the service is performed or ratably over the period of the related service contract.

Customers may obtain financing through third-party leasing companies to assist in their acquisition of our equipment products. Certain lease transactions classified as operating leases contain retained ownership provisions or guarantees, which results in recognition of revenue over the lease term. As a result, we defer the sale of these transactions and record the sales proceeds as collateralized borrowings or deferred revenue. The underlying equipment relating to operating leases is depreciated on a straight-line basis, not to exceed the equipment’s estimated useful life.

Revenues from contracts with multiple element arrangements are recognized as each element is earned. We offer service contracts in conjunction with equipment sales in addition to selling equipment and service contracts separately. Sales proceeds related to service contracts are deferred if the proceeds are received in advance of the service and recognized ratably over the contract period.

Share-based Compensation – We account for employee share-based compensation using the fair value based method. Our share-based compensation plans are more fully described in Note 15 of the Consolidated Financial Statements.

Research and Development – Research and development costs are expensed as incurred.

Advertising Costs –We advertise products, technologies and solutions to customers and prospective customers through a variety of marketing campaign and promotional efforts. These efforts include tradeshows, online advertising, e-mail marketing, mailings, sponsorships and telemarketing. Advertising costs are expensed as incurred. In 2013, 2012 and 2011 such activities amounted to $6,412, $6,466 and $6,728, respectively.

Income Taxes – Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the book and tax bases of existing assets and liabilities. A valuation allowance is provided when, in management’s judgment, it is more likely than not that some portion or all of the deferred tax asset will not be realized. We have established contingent tax liabilities using management’s best judgment. We follow guidance provided by Accounting Standards Codification ("ASC") 740, Income Taxes, regarding uncertainty in income taxes, to record these contingent tax liabilities (refer to Note 14 of the Consolidated Financial Statements for additional information). We adjust these liabilities as facts and circumstances change. Interest Expense is recognized in the first period the interest would begin accruing. Penalties are recognized in the period we claim or expect to claim the position in our tax return. Interest and penalties expenses are classified as an income tax expense.

Sales Tax –Sales taxes collected from customers and remitted to governmental authorities are presented on a net basis.

Earnings per Share – Basic earnings per share is computed by dividing Net Earnings by the Weighted Average Shares Outstanding during the period. Diluted earnings per share assume conversion of potentially dilutive stock options and restricted share awards. Performance-based shares are included in the calculation of diluted earnings per share in the quarter in which the performance targets have been achieved.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2013

Summary of Significant Accounting Policies [Abstract]

Nature of Operations

Nature of Operations – Our primary business is designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world. Our products include equipment for maintaining surfaces in industrial, commercial and outdoor environments; chemical-free and other sustainable cleaning technologies; and coatings for protecting, repairing and upgrading floors and other surfaces. We sell our products through our direct sales and service organization and a network of authorized distributors worldwide. Geographically, our customers are located in North America, Latin America, Europe, the Middle East, Africa and Asia Pacific.

Consolidation

Consolidation – The Consolidated Financial Statements include the accounts of Tennant Company and its subsidiaries. All intercompany transactions and balances have been eliminated. In these Notes to the Consolidated Financial Statements, Tennant Company is referred to as “Tennant,” “we,” “us,” or “our.”

Translations of Non-U.S. Currency

Translation of Non-U.S. Currency – Foreign currency-denominated assets and liabilities have been translated to U.S. dollars at year-end exchange rates, while income and expense items are translated at average exchange rates prevailing during the year. Gains or losses resulting from translation are included as a separate component of Accumulated Other Comprehensive Loss. The balance of cumulative foreign currency translation adjustments recorded within Accumulated Other Comprehensive Loss as of December 31, 2013, 2012 and 2011 was a net loss of $21,991, $19,734 and $20,283, respectively. The majority of translation adjustments are not adjusted for income taxes as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Net Foreign Currency Transaction (Losses) Gains are included in Other Income (Expense).

Use of Estimates

Use of Estimates – In preparing the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), management must make decisions that impact the reported amounts of assets, liabilities, revenues, expenses and the related disclosures, including disclosures of contingent assets and liabilities. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. Estimates are used in determining, among other items, sales promotions and incentives accruals, inventory valuation, warranty reserves, allowance for doubtful accounts, pension and postretirement accruals, useful lives for intangible assets, and future cash flows associated with impairment testing for goodwill and other long-lived assets. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors that management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. A number of these factors include, among others, economic conditions, credit markets, foreign currency, commodity cost volatility and consumer spending and confidence, all of which have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual amounts could differ significantly from those estimated at the time the consolidated financial statements are prepared. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash and Cash Equivalents

Cash and Cash Equivalents – We consider all highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents.

Restricted Cash

Restricted Cash – We have a total of $393 as of December 31, 2013 that serves as collateral backing certain bank guarantees and is therefore restricted. This money is invested in time deposits.

Receivables

Receivables – Credit is granted to our customers in the normal course of business. Receivables are recorded at original carrying value less reserves for estimated uncollectible accounts and sales returns. To assess the collectability of these receivables, we perform ongoing credit evaluations of our customers’ financial condition. Through these evaluations, we may become aware of a situation where a customer may not be able to meet its financial obligations due to deterioration of its financial viability, credit ratings or bankruptcy. The reserve requirements are based on the best facts available to us and are reevaluated and adjusted as additional information becomes available. Our reserves are also based on amounts determined by using percentages applied to trade receivables. These percentages are determined by a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. An account is considered past-due or delinquent when it has not been paid within the contractual terms. Uncollectible accounts are written off against the reserves when it is deemed that a customer account is uncollectible.

Inventories

Inventories – Inventories are valued at the lower of cost or market. Cost is determined on a first-in, first-out (“FIFO”) basis except for Inventories in North America and Japan which are determined on a last-in, first-out (“LIFO”) basis.

Property, Plant and Equipment

Property, Plant and Equipment – Property, plant and equipment is carried at cost. Additions and improvements that extend the lives of the assets are capitalized while expenditures for repairs and maintenance are expensed as incurred. We generally depreciate buildings and improvements by the straight-line method over a life of 30 years . Other property, plant and equipment are generally depreciated using the straight-line method based on lives of 3 years to 15 years.

Goodwill

Goodwill – Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. We analyze Goodwill on an annual basis as of year end and when an event occurs or circumstances change that may reduce the fair value of one of our reporting units below its carrying amount. A goodwill impairment occurs if the carrying amount of a reporting unit’s goodwill exceeds its fair value. In assessing the recoverability of Goodwill, we use an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.

Intangible Assets

Intangible Assets – Intangible Assets consist of definite lived customer lists, service contracts, an acquired trade name and technology. Intangible Assets with a definite life are amortized on a straight-line basis.

Impairment of Long-lived Assets

Impairment of Long-lived Assets – We periodically review our intangible and long-lived assets for impairment and assess whether events or circumstances indicate that the carrying amount of the assets may not be recoverable. We generally deem an asset group to be impaired if an estimate of undiscounted future operating cash flows is less than its carrying amount. If impaired, an impairment loss is recognized based on the excess of the carrying amount of the individual asset group over its fair value.

Purchases of Common Stock

Purchases of Common Stock – We repurchase our Common Stock under a 2011 and a 2012 repurchase program authorized by our Board of Directors. These programs allow us to repurchase up to 2,000,000 shares of our Common Stock. Upon repurchase, the par value is charged to Common Stock and the remaining purchase price is charged to Additional Paid-in Capital. If the amount of the remaining purchase price causes the Additional Paid-in Capital account to be in a debit position, this amount is then reclassified to Retained Earnings. Common Stock repurchased is included in shares authorized but is not included in shares outstanding.

Warranty

Warranty – We record a liability for estimated warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. In the event we determine that our current or future product repair and replacement costs exceed our estimates, an adjustment to these reserves would be charged to earnings in the period such determination is made. Warranty terms on machines range from one to four years.

Environmental

Environmental – We record a liability for environmental clean-up on an undiscounted basis when a loss is probable and can be reasonably estimated.

Pension and Profit Sharing Plans

Pension and Profit Sharing Plans – We have pension and/or profit sharing plans covering substantially all of our employees. Pension plan costs are accrued based on actuarial estimates with the required pension cost funded annually, as needed. No new participants have entered the pension plan since 2000.

Postretirement Benefits

Postretirement Benefits – We accrue and recognize the cost of retiree health benefits over the employees’ period of service based on actuarial estimates. Benefits are only available for U.S. employees hired before January 1, 1999.

Derivative Financial Instruments

Derivative Financial Instruments – 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. We periodically enter into various contracts, principally forward exchange contracts, to protect the value of certain of our foreign currency-denominated assets and liabilities (principally the Euro, Australian and Canadian dollars, British pound, Japanese yen, Chinese yuan and Brazilian real). We have elected not to apply hedge accounting treatment to these contracts as our contracts are for a short duration. These contracts are marked-to-market with the related asset or liability recorded in Other Current Assets or Other Current Liabilities, as applicable. The gains and losses on these contracts generally approximate changes in the value of the related assets and liabilities. Gains or losses on forward foreign exchange contracts to economically hedge foreign currency-denominated net assets and liabilities are recognized in Other Income (Expense) under Net Foreign Currency Transaction (Losses) Gains within the Consolidated Statements of Earnings.

Revenue Recognition

Revenue Recognition – We recognize revenue when persuasive evidence of an arrangement exists, title and risk of ownership have passed to the customer, the sales price is fixed or determinable and collectibility is reasonably assured. Generally, these criteria are met at the time the product is shipped. Provisions for estimated returns, rebates and discounts are provided for at the time the related revenue is recognized. Freight revenue billed to customers is included in Net Sales and the related shipping expense is included in Cost of Sales. Service revenue is recognized in the period the service is performed or ratably over the period of the related service contract.

Customers may obtain financing through third-party leasing companies to assist in their acquisition of our equipment products. Certain lease transactions classified as operating leases contain retained ownership provisions or guarantees, which results in recognition of revenue over the lease term. As a result, we defer the sale of these transactions and record the sales proceeds as collateralized borrowings or deferred revenue. The underlying equipment relating to operating leases is depreciated on a straight-line basis, not to exceed the equipment’s estimated useful life.

Revenues from contracts with multiple element arrangements are recognized as each element is earned. We offer service contracts in conjunction with equipment sales in addition to selling equipment and service contracts separately. Sales proceeds related to service contracts are deferred if the proceeds are received in advance of the service and recognized ratably over the contract period.

Share-based Compensation

Share-based Compensation – We account for employee share-based compensation using the fair value based method. Our share-based compensation plans are more fully described in Note 15 of the Consolidated Financial Statements.

Research and Development

Research and Development – Research and development costs are expensed as incurred.

Advertising Costs

Advertising Costs –We advertise products, technologies and solutions to customers and prospective customers through a variety of marketing campaign and promotional efforts. These efforts include tradeshows, online advertising, e-mail marketing, mailings, sponsorships and telemarketing. Advertising costs are expensed as incurred. In 2013, 2012 and 2011 such activities amounted to $6,412, $6,466 and $6,728, respectively.

Income Taxes

Income Taxes – Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the book and tax bases of existing assets and liabilities. A valuation allowance is provided when, in management’s judgment, it is more likely than not that some portion or all of the deferred tax asset will not be realized. We have established contingent tax liabilities using management’s best judgment. We follow guidance provided by Accounting Standards Codification ("ASC") 740, Income Taxes, regarding uncertainty in income taxes, to record these contingent tax liabilities (refer to Note 14 of the Consolidated Financial Statements for additional information). We adjust these liabilities as facts and circumstances change. Interest Expense is recognized in the first period the interest would begin accruing. Penalties are recognized in the period we claim or expect to claim the position in our tax return. Interest and penalties expenses are classified as an income tax expense.

Sales Tax

Sales Tax –Sales taxes collected from customers and remitted to governmental authorities are presented on a net basis.

Earnings per Share

Earnings per Share – Basic earnings per share is computed by dividing Net Earnings by the Weighted Average Shares Outstanding during the period. Diluted earnings per share assume conversion of potentially dilutive stock options and restricted share awards. Performance-based shares are included in the calculation of diluted earnings per share in the quarter in which the performance targets have been achieved.

14. Income Taxes

Income from continuing operations for the three years ended December 31, was as follows:

	2013		2012		2011
U.S. operations	$	54,702	$	47,220	$	40,282
Foreign operations	5,176		12,670		8,448

Income tax expense (benefit) for the three years ended December 31, was as follows:

Total Income Tax Expense	$	19,647		$	18,306		$	16,017

U.S. income taxes have not been provided on approximately $23,596 of undistributed earnings of non-U.S. subsidiaries. We do not have any plans to repatriate the undistributed earnings. Any repatriation from foreign subsidiaries that would result in incremental U.S. taxation is not being considered. It is management’s belief that reinvesting these earnings outside the U.S. is the most efficient use of capital.

We have Dutch and German tax loss carryforwards of approximately $18,046 and $15,674, respectively. If unutilized, the Dutch tax loss carryforward will expire after 9 years. The German tax loss carryforward has no expiration date. Because of the uncertainty regarding realization of the Dutch tax loss carryforward, a valuation allowance was established. This valuation allowance increased in 2013 due to results of operations.

We have U.S. foreign tax credit carryforwards of approximately $3,157. If unutilized, foreign tax credit carryforwards will expire in 2020. Based upon evaluation, as of December 31, 2013, no valuation allowance has been recorded. We have Dutch foreign tax credit carryforwards of $922. Because of the uncertainty regarding utilization of the Dutch foreign tax credit carryforward, a valuation allowance was established.

A valuation allowance for the remaining deferred tax assets is not required since it is more likely than not that they will be realized through carryback to taxable income in prior years, future reversals of existing taxable temporary differences and future taxable income.

Our effective income tax rate varied from the U.S. federal statutory tax rate for the three years ended December 31, as follows:

	2013		2012		2011
Tax at statutory rate	35.0	%	35.0	%	35.0	%
Increases (decreases) in the tax rate from:
State and local taxes, net of federal benefit	1.7		1.0		2.0
Effect of foreign operations	(3.3	)	(6.2	)	0.5
Effect of changes in valuation allowances	3.7		2.3		—
Domestic production activities deduction	(1.6	)	(1.5	)	(1.6	)
Other, net	(2.7	)	—		(3.0	)
Effective income tax rate	32.8	%	30.6	%	32.9	%

Deferred tax assets and liabilities were comprised of the following as of December 31:

	2013			2012			2011
Deferred Tax Assets:
Inventories, principally due to additional costs inventoried for tax purposes and changes in inventory reserves	$	—		$	28		$	426
Employee wages and benefits, principally due to accruals for financial reporting purposes	14,831			18,608			20,910
Warranty reserves accrued for financial reporting purposes	2,803			2,641			2,625
Receivables, principally due to allowance for doubtful accounts and tax accounting method for equipment rentals	1,593			1,540			1,464
Tax loss carryforwards	8,696			6,619			5,915
Tax credit carryforwards	4,078			6,720			8,554
Other	2,523			2,329			1,777
Gross Deferred Tax Assets	$	34,524		$	38,485		$	41,671
Less: valuation allowance	(7,243		)	(4,719		)	(3,229		)
Total Net Deferred Tax Assets	$	27,281		$	33,766		$	38,442
Deferred Tax Liabilities:
Inventories, principally due to changes in inventory reserves	$	306		$	—		$	—
Property, Plant and Equipment, principally due to differences in depreciation and related gains	7,446			7,945			9,167
Goodwill and Intangible Assets	6,253			6,818			7,093
Total Deferred Tax Liabilities	$	14,005		$	14,763		$	16,260
Net Deferred Tax Assets	$	13,276		$	19,003		$	22,182

The valuation allowance at December 31, 2013 principally applies to Dutch tax loss and tax credit carryforwards that, in the opinion of management, are more likely than not to expire unutilized. However, to the extent that tax benefits related to these carryforwards are realized in the future, the reduction in the valuation allowance will reduce income tax expense.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2013			2012
Balance at January 1,	$	3,480		$	3,424
Increases as a result of tax positions taken during a prior period	155			—
Increases as a result of tax positions taken during the current year	508			611
Reductions as a result of a lapse of the applicable statute of limitations	(295		)	(447		)
Decreases as a result of foreign currency fluctuations	(188		)	(108		)
Balance at December 31,	$	3,660		$	3,480

Included in the balance of unrecognized tax benefits at December 31, 2013 and 2012 are potential benefits of $3,384 and $3,259, respectively, that if recognized, would affect the effective tax rate from continuing operations.

We recognize potential accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. In addition to the liability of $3,660 and $3,480 for unrecognized tax benefits as of December 31, 2013 and 2012 was approximately $525 and $462, respectively, for accrued interest and penalties. To the extent interest and penalties are not assessed with respect to uncertain tax positions, the amounts accrued will be revised and reflected as an adjustment to income tax expense.

We 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 are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2007 to 2011. Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.

We do not anticipate that total unrecognized tax benefits will change significantly within the next 12 months.

Options to purchase 132,803, 233,655 and 123,292 shares of Common Stock were outstanding during 2013, 2012 and 2011, respectively, but were not included in the computation of diluted earnings per share. These exclusions are made if the exercise prices of these options are greater than the average market price of our Common Stock for the period, if the number of shares we can repurchase under the treasury stock method exceeds the weighted shares outstanding in the options, or if we have a net loss, as the effects are anti-dilutive.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

10. Fair Value Measurements

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 December 31, 2013 is as follows:

	Fair Value		Level 1		Level 2		Level 3
Assets:
Foreign currency forward exchange contracts	$	16	$	—	$	16	$	—
Total Assets	$	16	$	—	$	16	$	—
Liabilities:
Foreign currency forward exchange contracts	$	109	$	—	$	109	$	—
Total Liabilities	$	109	$	—	$	109	$	—

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 to economically hedge foreign currency-denominated assets and liabilities are recognized in Other Current Assets and Other Current Liabilities within the Consolidated Balance Sheets and are recognized in Other Income (Expense) under Net Foreign Currency Transaction (Losses) Gains within the Consolidated Statements of Earnings. As of December 31, 2013 the fair value of such contracts outstanding was an asset of $16 and a liability of $109. As of December 31, 2012 the fair value of such contracts outstanding was an asset of $388 and a liability of $404. We recognized a net gain of $1,068 during 2013, a net gain of $1,026 during 2012 and a net loss of $1,444 during 2011. At December 31, 2013 and 2012, the notional amounts of foreign currency forward exchange contracts outstanding were $30,280 and $42,475, respectively.

The carrying amounts reported in the Consolidated Balance Sheets for Cash and Cash Equivalents, Restricted Cash, Receivables, Other Current Assets, Short-Term Debt, Accounts Payable and Other Current Liabilities approximate fair value due to their short-term nature.

The fair market 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.

4. Acquisitions and Divestitures

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 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.

The components of the purchase price of the business combination described above have been allocated as follows:

Current Assets	$	426
Property, Plant and Equipment, Net	167
Identified Intangible Assets	3,800
Goodwill	472
Total Assets Acquired	4,865
Current Liabilities	409
Total Liabilities Assumed	409
Net Assets Acquired	$	4,456

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 $2,963 as of December 31, 2013, 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 in our Profit from Operations in the Consolidated Statements of Earnings for the year ended December 31, 2012.

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 19, M&F is a related party to Tennant. 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 Tennant is not the primary beneficiary of this VIE. The only financing Tennant has 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.

The assets and liabilities transferred under the Share Purchase Agreement on the date of sale were as follows:

Accounts Receivable	$	4,398
Inventories	4,271
Other Current Assets	87
Current Assets	8,756
Property, Plant and Equipment, Net	170

Share-Based Compensation

Share-based Compensation [Abstract]

Share-Based Compensation

15. Share-Based Compensation

We have five plans under which we have awarded share-based compensation grants: The 1995 Stock Incentive Plan (“1995 Plan”) and 1999 Amended and Restated Stock Incentive Plan (“1999 Plan”), which provided for share-based compensation grants to our executives and key employees, the 1997 Non-Employee Directors Option Plan (“1997 Plan”), which provided for stock option grants to our non-employee Directors, the 2007 Stock Incentive Plan (“2007 Plan”) and the Amended and Restated 2010 Stock Incentive Plan, as Amended (“2010 Plan”), which were adopted as a continuing step toward aggregating our equity compensation programs to reduce the complexity of our equity compensation programs.

The 1995 and 1997 Plans were terminated in 2006 and all remaining shares were transferred to the 1999 Plan as approved by the shareholders in 2006. Awards granted under the 1995 and 1997 Plans prior to 2006 that remain outstanding continue to be governed by the respective plan under which the grant was made. Upon approval of the 1999 Plan in 2006, we ceased making grants of future awards under these plans and subsequent grants of future awards were made from the 1999 Plan and governed by its terms.

The 2007 Plan terminated our rights to grant awards under the 1999 Plan except that the 1999 Plan will remain available for grants of reload options upon exercise of previously granted options with one-time reload features. We have not granted options with reload features since March 1, 2004. Awards previously granted under the 1999 Plan remain outstanding and continue to be governed by the terms of that plan.

The 2010 Plan, originally approved by our shareholders on April 28, 2010 and amended and restated by our shareholders on April 25, 2012, terminated our rights to grant awards under the 2007 Plan; however, any awards granted under the 2007 or 2010 Plans that do not result in the issuance of shares of Common Stock may again be used for an award under the 2010 Plan. The 2010 Plan was amended and restated by our shareholders on April 24, 2013, increasing the number of shares available under the amended 2010 Plan from 1,500,000 shares to 2,600,000 shares.

As of December 31, 2013, there were 499,248 shares reserved for issuance under the 1995 Plan, the 1997 Plan, the 1999 Plan and the 2007 Plan for outstanding compensation awards and 1,643,264 shares were available for issuance under the 2010 Plan for current and future equity awards. The Compensation Committee of the Board of Directors determines the number of shares awarded and the grant date, subject to the terms of our equity award policy.

We recognized total Share-Based Compensation Expense of $6,116, $9,092 and $5,407, respectively, during the years ended 2013, 2012 and 2011. The total excess tax benefit recognized for share-based compensation arrangements during the years ended 2013, 2012 and 2011 was $5,178, $2,047 and $1,266, respectively.

Stock Option Awards

We determined the fair value of our stock option awards using the Black-Scholes valuation model that uses the assumptions noted in the table below. The expected life selected for stock options granted during the year represents the period of time that the stock options are expected to be outstanding based on historical data of stock option holder exercise and termination behavior of similar grants. The risk-free interest rate for periods within the contractual life of the stock option is based on the U.S. Treasury rate over the expected life at the time of grant. Expected volatilities are based upon historical volatility of our stock over a period equal to the expected life of each stock option grant. Dividend yield is estimated over the expected life based on our dividend policy and historical dividends paid. We use historical data to estimate pre-vesting forfeiture rates and revise those estimates in subsequent periods if actual forfeitures differ from those estimates.

The following table illustrates the valuation assumptions used for the 2013, 2012 and 2011 grants:

	2013	2012	2011
Expected volatility	51%	51 - 52%	49 - 50%
Weighted-average expected volatility	51%	52%	49%
Expected dividend yield	1.6%	1.6 - 1.7%	1.7 - 1.8%
Weighted-average expected dividend yield	1.6%	1.7%	1.8%
Expected term, in years	6	0.2 - 6	6
Risk-free interest rate	0.9 - 1.1%	0.1 - 1.1%	1.3 - 2.5%

Employee stock option awards prior to 2005 include a reload feature for options granted to key employees. This feature allows employees to exercise options through a stock-for-stock exercise using mature shares, and employees are granted a new stock option (reload option) equal to the number of shares of Common Stock used to satisfy both the exercise price of the option and the minimum tax withholding requirements. The reload options granted have an exercise price equal to the fair market value of the Common Stock on the grant date. Stock options granted in conjunction with reloads vest immediately and have a term equal to the remaining life of the initial grant. Compensation expense is fully recognized for reload stock options as of the reload date.

Beginning in 2004, new stock option awards granted vest one-third each year over a three year period and have a ten year contractual term. These grants do not contain a reload feature. Compensation expense equal to the grant date fair value is recognized for these awards over the vesting period.

In addition to stock options, we also occasionally grant cash-settled stock appreciation rights (“SARs”) to employees in certain foreign locations. There were no outstanding SARs as of December 31, 2013 and no SARs were granted during 2013, 2012 or 2011.

The following table summarizes the activity during the year ended December 31, 2013 for stock option awards:

	Shares		Weighted-Average Exercise Price
Outstanding at beginning of year	1,191,421		$	24.16
Granted	142,755		46.96
Exercised	(445,266	)	18.67
Forfeited	(11,588	)	42.34
Outstanding at end of year	877,322		$	30.42
Exercisable at end of year	601,747		$	23.89

The weighted-average grant date fair value of stock options granted during the years ended December 31, 2013, 2012 and 2011 was $19.62, $16.60 and $16.67, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2013, 2012 and 2011 was $15,641, $5,826 and $5,600, respectively. The aggregate intrinsic value of options outstanding and exercisable at December 31, 2013 was $32,805 and $26,427, respectively. The weighted-average remaining contractual life for options outstanding and exercisable as of December 31, 2013, was 7 years and 6 years, respectively. As of December 31, 2013, there was unrecognized compensation cost for nonvested options of $3,102 which is expected to be recognized over a weighted-average period of 1.6 years.

Restricted Share Awards

Restricted share awards for employees generally have a three year vesting period from the effective date of the grant. Restricted share awards to non-employee directors vest upon a change of control or upon termination of service as a director occurring at least six months after grant date of the award so long as termination is for one of the following reasons: death; disability; retirement in accordance with Tennant policy (e.g., age, term limits, etc.); resignation at request of Board (other than for gross misconduct); resignation following at least six months’ advance notice; failure to be renominated (unless due to unwillingness to serve) or reelected by shareholders; or removal by shareholders.

The following table summarizes the activity during the year ended December 31, 2013, for nonvested restricted share awards:

	Shares		Weighted-Average Grant Date Fair Value
Nonvested at beginning of year	142,354		$	33.40
Granted	34,508		48.04
Vested	(24,866	)	26.06
Forfeited	(1,053	)	40.02
Nonvested at end of year	150,943		$	37.89

The total fair value of shares vested during the year ended December 31, 2013, 2012 and 2011 was $643, $861 and $650, respectively. As of December 31, 2013, there was $1,993 of total unrecognized compensation cost related to nonvested shares which is expected to be recognized over a weighted-average period of 2.1 years.

Performance Share Awards

We grant performance share awards to key employees as a part of our long-term management compensation program. These awards are earned based upon achievement of certain financial performance targets over a three year period. We determine the fair value of these awards as of the date of grant and recognize the expense over a three year performance period. Performance shares are granted in restricted stock units. They are payable in stock and vest solely upon achievement of certain financial performance targets during this three year period.

The 2013 performance share award covers the three year performance period from the beginning of fiscal year 2013 to the end of fiscal year 2015. The 2012 performance share award covers the three year performance period from the beginning of fiscal year 2012 to the end of fiscal year 2014. The 2011 performance share award covered the three year performance period from the beginning of fiscal year 2011 to the end of fiscal year 2013.

The 2010 performance share award covered the three year performance period from the beginning of fiscal year 2010 to the end of fiscal year 2012. Performance shares were granted in restricted stock units. They were paid in cash and vested solely upon achievement of certain financial performance targets during this three year period.

In 2009, we granted a combination of stock options, restricted stock awards and restricted stock units payable in cash to key employees as part of our management compensation program and did not grant performance share awards. These stock options and restricted share awards vested over a three year period and did not contain a performance requirement.

Share-Based Liabilities

As of December 31, 2013 and 2012, we had $292 and $3,650 in total share-based liabilities recorded on our Consolidated Balance Sheets, respectively. During the years ended December 31, 2013, 2012 and 2011 we paid out $3,134, $2,212 and $506 related to 2010, 2009 and 2008 share-based liability awards, respectively.

Retirement Benefit Plans

11. Retirement Benefit Plans

Substantially all U.S. employees are covered by various retirement benefit plans, including defined benefit pension plans, post-retirement medical plans and defined contribution savings plans. Retirement benefits for eligible employees in foreign locations are funded principally through defined benefit plans, annuity or government programs. The total cost of benefits for our plans was $11,766, $11,192 and $11,271 in 2013, 2012 and 2011, respectively.

We have a qualified, funded defined benefit retirement plan (the “U.S. Pension Plan”) in the U.S. covering certain current and retired employees. Plan benefits are based on the years of service and compensation during the highest five consecutive years of service in the final ten years of employment. No new participants have entered the plan since 2000. The plan has 442 participants including 90 active employees as of December 31, 2013.

We have a U.S. postretirement medical benefit plan (the “U.S. Retiree Plan”) to provide certain healthcare benefits for U.S. employees hired before January 1, 1999. Eligibility for those benefits is based upon a combination of years of service with Tennant and age upon retirement.

Our defined contribution savings plan (“401(k)”) covers substantially all U.S. employees. Under this plan, we match up to 3% of the employee’s annual compensation in cash to be invested per their election. We also make a profit sharing contribution to the 401(k) plan for employees with more than one year of service in accordance with our Profit Sharing Plan. This contribution is based upon our financial performance and can be funded in the form of Tennant stock, cash or a combination of both. Expenses for the 401(k) plan were $6,423, $6,226 and $6,864 during 2013, 2012 and 2011, respectively.

We have a U.S. nonqualified supplemental benefit plan (the “U.S. Nonqualified Plan”) to provide additional retirement benefits for certain employees whose benefits under our 401(k) plan or U.S. Pension Plan are limited by either the Employee Retirement Income Security Act or the Internal Revenue Code.

We also have defined pension benefit plans in the United Kingdom and Germany (the “U.K. Pension Plan” and the “German Pension Plan”). The U.K. Pension Plan and German Pension Plan cover certain current and retired employees and both plans are closed to new participants.

On March 23, 2010, the Patient Protection and Affordable Care Act (the “PPACA”) was signed into law, and, on March 30, 2010, the Health Care and Education Reconciliation Act of 2010 (the “HCERA” and, together with PPACA, the “Acts”), which makes various amendments to certain aspects of the PPACA, was signed into law. The Acts effectively change the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that provide prescription drug benefits that are at least actuarially equivalent to the corresponding benefits provided under Medicare Part D. Under the Acts, an employer’s income tax deduction for the costs of providing Medicare Part D-equivalent prescription drug benefits to retirees will be reduced by the amount of the federal subsidy beginning in 2013. Under U.S. GAAP, any impact from a change in tax law must be recognized in earnings in the period enacted regardless of the effective date. The Acts did not have a material impact on our financial position or results of operations.

We expect to contribute approximately $149 to our U.S. Nonqualified Plan, $919 to our U.S. Retiree Plan, $237 to our U.K. Pension Plan and $41 to our German Pension Plan in 2014. No contributions to the U.S. Pension Plan are expected to be required during 2014. There were no contributions made to the U.S. Pension Plan during 2013. During 2012, we made a $15,000 discretionary contribution to the U.S. Pension Plan in addition to the minimum funding requirements for 2011 and 2012.

Weighted-average asset allocations by asset category of the U.S. and U.K. Pension Plans as of December 31, 2013 are as follows:

Estimates of the fair value of U.S. and U.K Pension Plan assets are based on the framework established in the accounting guidance for fair value measurements. A brief description of the three levels can be found in Note 10. Equity Securities and Mutual Funds traded in active markets are classified as Level 1. The Investment Account held by Pension Plan invests in insurance contracts for purposes of funding the U.K. Pension Plan and are classified as Level 3. The fair value of the Investment Account are the cash surrender values as determined by the provider which are the amounts the plan would receive if the contracts were cashed out at year end. The underlying assets held by these contracts are primarily invested in assets traded in active markets.

A reconciliation of the beginning and ending balances of the Level 3 investments of our U.K. Pension Plan during the years ended are as follows:

	2013		2012
Fair value at beginning of year	$	8,855	$	7,738
Purchases, sales, issuances and settlements, net	74		—
Net gain	601		739
Foreign currency	203		378
Fair value at end of year	$	9,733	$	8,855

The primary objective of our U.S. and U.K. Pension Plans is to meet retirement income commitments to plan participants at a reasonable cost to us and to maintain a sound actuarially funded status. This objective is accomplished through growth of capital and safety of funds invested. The pension plans' assets are invested in securities to achieve growth of capital over inflation through appreciation and accumulation and reinvestment of dividend and interest income. Investments are diversified to control risk. The target allocation for the U.S. Pension Plan is 60% equity and 40% debt securities. Equity securities within the U.S. Pension Plan do not include any direct investments in Tennant Company Common Stock. The U.K. Pension Plan is invested in insurance contracts with underlying investments primarily in equity and fixed income securities. Our German Pension Plan is unfunded, which is customary in that country.

Weighted-average assumptions used to determine benefit obligations as of December 31, are as follows:

Weighted-average assumptions used to determine net periodic benefit costs as of December 31, are as follows:

	U.S. Pension Benefits						Non-U.S. Pension Benefits						Postretirement Medical Benefits
	2013		2012		2011		2013		2012		2011		2013		2012		2011

Rate of compensation increase	3.00	%	3.00	%	3.00	%	4.50	%	4.60	%	5.10	%	—		—		—

The discount rate is used to discount future benefit obligations back to today’s dollars. Our discount rates were determined based on high-quality fixed income investments. The resulting discount rates are consistent with the duration of plan liabilities. The Citigroup Above Median Spot Rate is used in determining the discount rate for the U.S. Plans. The expected return on assets assumption on the investment portfolios for the pension plans is based on the long-term expected returns for the investment mix of assets currently in the portfolio. Management uses historic return trends of the asset portfolio combined with recent market conditions to estimate the future rate of return.

The accumulated benefit obligations as of December 31, for all defined benefit plans, are as follows:

	2013		2012
U.S. Pension Plans	$	42,241	$	46,907
U.K. Pension Plan	9,803		8,837
German Pension Plan	897		878

Goodwill and Intangible Assets

7. Goodwill and Intangible Assets

For purposes of performing our goodwill impairment analysis, we have identified our reporting units as North America; Latin America; Europe, Middle East, Africa (“EMEA”) and Asia Pacific. As of December 31, 2013, 2012 and 2011, we performed an analysis of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Based on our analysis of qualitative factors, we determined that it was not necessary to perform the two-step goodwill impairment test for any of our reporting units.

The changes in the carrying amount of Goodwill are as follows:

	Goodwill		Accumulated Impairment Losses			Total
Balance as of December 31, 2011	$	66,523	$	(46,220	)	$	20,303

During the second quarter of 2011, we impaired customer lists and technology Intangible Assets totaling $1,805 related to the obsolescence of the two Hofmans outdoor city cleaning products in Europe. This impairment charge is included within Selling and Administrative Expense in the 2011 Consolidated Statement of Earnings.

Amortization expense on Intangible Assets was $2,560, $2,800 and $3,330 for the years ended December 31, 2013, 2012 and 2011, respectively.

Commitment fees on unused lines of credit for the year ended December 31, 2013 were $307.

Our most restrictive covenants are part of our Credit Agreement with JPMorgan, which are the same covenants in our Shelf Agreement with Prudential described below, and require us to maintain an indebtedness to EBITDA ratio of not greater than 3.00 to 1 and to maintain an EBITDA to interest expense ratio of no less than 3.50 to 1 as of the end of each quarter. As of December 31, 2013, our indebtedness to EBITDA ratio was 0.41 to 1 and our EBITDA to interest expense ratio was 48.00 to 1.

Credit Facilities

JPMorgan Chase Bank, National Association

On April 25, 2013, we entered into Amendment No. 1 to our 2011 Credit Agreement which amends the Credit Agreement, dated as of May 5, 2011, with JPMorgan Chase Bank, N. A. (“JPMorgan”), as administrative agent and collateral agent, U.S. Bank National Association, as syndication agent, Wells Fargo Bank, National Association, and RBS Citizens, N.A., as co-documentation agents, and the Lenders (including JPMorgan) from time to time party thereto (the “2011 Credit Agreement”). Under the original terms, the 2011 Credit Agreement provides us and certain of our foreign subsidiaries access to a senior unsecured credit facility until May 5, 2016, in the amount of $125,000, with an option to expand by up to $62,500 to a total of $187,500. Borrowings may be denominated in U.S. Dollars or certain other currencies. The 2011 Credit Agreement contains a $100,000 sublimit on borrowings by foreign subsidiaries.

Under the original terms of the 2011 Credit Agreement, the fee for committed funds ranges from an annual rate of 0.25% to 0.40%, depending on our leverage ratio. Eurocurrency borrowings under the 2011 Credit Agreement bear interest at a rate per annum equal to adjusted LIBOR plus an additional spread of 1.50% to 2.10%, depending on our leverage ratio. Alternate Base Rate (“ABR”) borrowings bear interest at a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.50% to 1.10%, depending on our leverage ratio.

Effective April 25, 2013, Amendment No. 1 to the 2011 Credit Agreement principally provides the following changes to the 2011 Credit Agreement:

• extends the maturity date of the 2011 Credit Agreement to March 1, 2018;

• changes the fees for committed funds under the 2011 Credit Agreement to an annual rate ranging from 0.20% to 0.35%, depending on our leverage ratio;

• changes the per annum interest rate on Eurocurrency borrowings to adjusted LIBOR plus an additional spread of 1.30% to 1.90%, depending on our leverage ratio;

• changes the ABR rate at which borrowings bear interest to a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.30% to 0.90%, depending on our leverage ratio; and

• changes related to new or recently revised financial regulations.

The 2011 Credit Agreement gives the Lenders a pledge of 65% of the stock of certain first tier foreign subsidiaries. The obligations under the 2011 Credit Agreement are also guaranteed by certain of our first tier domestic subsidiaries.

The 2011 Credit Agreement contains customary representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and merge or consolidate with another entity. Further, the 2011 Credit Agreement contains the following covenants:

• a covenant requiring us to maintain an indebtedness to EBITDA ratio as of the end of each quarter of not greater than 3.00 to 1;

• a covenant requiring us to maintain an EBITDA to interest expense ratio as of the end of each quarter of no less than 3.50 to 1;

• a covenant restricting us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and

• a covenant restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

As of December 31, 2013 we were in compliance with all covenants under the Credit Agreement. There was $10,000 in outstanding borrowings under this facility at December 31, 2013, with a weighted average interest rate of 1.47%.

Prudential Investment Management, Inc.

On July 29, 2009, we entered into a Private Shelf Agreement (the “Shelf Agreement”) with Prudential Investment Management, Inc. (“Prudential”) and Prudential affiliates from time to time party thereto. The Shelf Agreement provides us and our subsidiaries access to an uncommitted, senior secured, maximum aggregate principal amount of $80,000 of debt capital. The Shelf Agreement contains representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and to merge or consolidate with another entity. The Shelf Agreement limits the payment of dividends or repurchases of stock to an amount ranging from $12,000 to $40,000 based on our leverage ratio after giving effect to such payments.

On May 5, 2011, we entered into Amendment No. 1 to our Private Shelf Agreement (the “Amendment”).

The Amendment principally provides the following changes to the Shelf Agreement:

• elimination of the security interest in our personal property and subsidiaries;

• an amendment to the maximum leverage ratio to not greater than 3.00 to 1 for any period ending on or after March 31, 2011;

• an amendment to our restriction regarding the payment of dividends or repurchase of stock to restrict us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and

• an amendment to Permitted Acquisitions restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

On July 24, 2012, we entered into Amendment No. 2 to our Private Shelf Agreement (“Amendment No. 2”), which amends the Shelf Agreement. The principal change effected by Amendment No. 2 is an extension of the Issuance Period for Shelf Notes under the Shelf Agreement. The Issuance Period now expires on July 24, 2015.

As of December 31, 2013, there was $20,000 in outstanding borrowings under this facility; the $10,000 Series A notes issued in March 2011 with a fixed interest rate of 4.00% and a 7 year term serially maturing from 2014 to 2018; and the $10,000 Series B notes issued in June 2011 with a fixed interest rate of 4.10% and a 10 year term serially maturing from 2015 to 2021. We were in compliance with all covenants of the Shelf Agreement as of December 31, 2013.

The Royal Bank of Scotland Citizens, N.A.

On September 14, 2010, we entered into an overdraft facility with The Royal Bank of Scotland Citizens, N.A. in the amount of 2,000 Euros or approximately $2,757. There was no balance outstanding on this facility as of December 31, 2013.

HSBC Bank (China) Company Limited, Shanghai Branch

On June 20, 2012, we entered into a banking facility with the HSBC Bank (China) Company Limited, Shanghai Branch in the amount of $5,000. There was $1,500 in outstanding borrowings on this facility as of December 31, 2013, with a fixed interest rate of 5.1%.

Notes Payable

On May 31, 2011, we incurred $1,500 in debt related to installment payments due to the former owners of Water Star in connection with our acquisition of Water Star, of which none remains outstanding as of December 31, 2013.

Collateralized Borrowings

Collateralized borrowings represent deferred sales proceeds on certain leasing transactions with third-party leasing companies. These transactions are accounted for as borrowings, with the related assets capitalized as property, plant and equipment and depreciated straight-line over the lease term.

Capital Lease Obligations

Capital lease obligations outstanding are primarily related to sale-leaseback transactions with third-party leasing companies whereby we sell our manufactured equipment to the leasing company and lease it back. The equipment covered by these leases is rented to our customers over the lease term.

The aggregate maturities of our outstanding debt including capital lease obligations as of December 31, 2013, are as follows:

2014	$	4,718

Commitments and Contingencies

13. Commitments and Contingencies

We lease office and warehouse facilities, vehicles and office equipment under operating lease agreements, which include both monthly and longer-term arrangements. Leases with initial terms of one year or more expire at various dates through 2020 and generally provide for extension options. Rent expense under the leasing agreements (exclusive of real estate taxes, insurance and other expenses payable under the leases) amounted to $17,873, $17,524 and $17,375 in 2013, 2012 and 2011, respectively.

The minimum rentals for aggregate lease commitments as of December 31, 2013, were as follows:

2014	$	8,398
2015	5,378
2016	3,129
2017	1,892
2018	778
Thereafter	311
Total	$	19,886

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. The aggregate residual value at lease expiration of those leases is $11,741, of which we have guaranteed $7,659. As of December 31, 2013, we have recorded a liability for the estimated end-of-term loss related to this residual value guarantee of $398 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 first quarter of 2013, we renewed our lease for our Louisville facility. This lease has a five year term with a total commitment of $4,710.

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 $1,306 remains outstanding as of December 31, 2013.

In the ordinary course of business, we may become liable with respect to pending and threatened litigation, tax, environmental and other matters. While the ultimate results of current claims, investigations and lawsuits involving us are unknown at this time, we do not expect that these matters will have a material adverse effect on our consolidated financial position or results of operations. Legal costs associated with such matters are expensed as incurred.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Newly Adopted Accounting Pronouncements

2. Newly Adopted Accounting Pronouncements

Offsetting Assets and Liabilities Disclosures

In December 2011, the Financial Accounting Standards Board (“FASB”) issued updated accounting guidance on disclosures about offsetting assets and liabilities. This update adds certain additional disclosure requirements about financial instruments and derivative instruments that are subject to netting arrangements. The new disclosures are required for interim and annual reporting periods beginning on or after January 1, 2013. This guidance did not have a material impact on our results of operations or financial position.

Comprehensive Income

In February 2013, the FASB issued new disclosure requirements for items reclassified out of accumulated other comprehensive income. The requirements do not change the existing accounting and reporting for net income or other comprehensive income. The requirements are effective for annual reporting periods beginning after December 15, 2012. The requirements did not impact our results of operations or financial position.

Shareholders' Equity

12 Months Ended

Dec. 31, 2013

Stockholders' Equity Note [Abstract]

Shareholders' Equity

12. Shareholders' Equity

Authorized Shares

We are authorized to issue an aggregate of 61,000,000 shares; 60,000,000 are designated as Common Stock, having a par value of $0.375 per share, and 1,000,000 are designated as Preferred Stock, having a par value of $0.02 per share. The Board of Directors is authorized to establish one or more series of preferred stock, setting forth the designation of each such series, and fixing the relative rights and preferences of each such series.

Purchase Rights

On November 10, 2006, the Board of Directors approved a Rights Agreement and declared a dividend of one preferred share purchase right for each outstanding share of Common Stock. Each right entitles the registered holder to purchase from us one one-hundredth of a Series A Junior Participating Preferred Share of the par value of $0.02 per share at a price of $100 per one hundredth of a Preferred Share, subject to adjustment. The rights are not exercisable or transferable apart from the Common Stock until the earlier of: (i) the close of business on the fifteenth day following a public announcement that a person or group of affiliated or associated persons has become an “Acquiring Person” (i.e., has become, subject to certain exceptions, including for stock ownership by employee benefit plans, the beneficial owner of 20% or more of the outstanding Common Stock), or (ii) the close of business on the fifteenth day following the first public announcement of a tender offer or exchange offer the consummation of which would result in a person or group of affiliated or associated persons becoming, subject to certain exceptions, the beneficial owner of 20% or more of the outstanding Common Stock (or such later date as may be determined by our Board of Directors prior to a person or group of affiliated or associated persons becoming an Acquiring Person). After a person or group becomes an Acquiring Person, each holder of a Right (other than an Acquiring Person) will be able to exercise the right at the current exercise price of the Right and receive the number of shares of Common Stock having a market value of two times the exercise price of the right, or, depending upon the circumstances in which the rights became exercisable, the number of common shares of the Acquiring Person having a market value of two times the exercise price of the right. At no time do the rights have any voting power. We may redeem the rights for $0.001 per right at any time prior to a person or group acquiring 20% or more of the Common Stock. Under certain circumstances, the Board of Directors may exchange the rights for our Common Stock or reduce the 20% thresholds to not less than 10%. The rights will expire on December 26, 2016, unless extended or earlier redeemed or exchanged by us.
