EXPLANATORY NOTE 

In December 2009, Koss Corporation (the “Company”) learned of certain unauthorized transactions made by Sujata Sachdeva, its 
former Vice President of Finance and Principal Accounting Officer.  The Company first learned of the unauthorized transactions on 
December 18, 2009, when Michael Koss received a call from American Express security informing him that certain wire transfers 
were being made from Koss corporate bank accounts to pay personal American Express expenses of Ms. Sachdeva.  These wire 
transfers were part of the unauthorized transactions made by Ms. Sachdeva resulting in the misappropriation of approximately 
$31,500,000 from fiscal year 2005 through December 2009.  The Company subsequently learned that Ms. Sachdeva colluded with two 
other employees of the accounting department in the misappropriation and circumvention of the Company’s then existing internal 
controls and established operating procedures.  The collusion of these former employees, and the actions the Company took to remedy 
such collusion and circumvention, are described in detail in the Company’s Annual Report on Form 10-K/A filed for the year ended 
June 30, 2009 and in “Item 9A. Controls and Procedures” in this Annual Report on Form 10-K.  In July 2010, Ms. Sachdeva pleaded 
guilty in the criminal case filed against her; and her sentencing is currently scheduled for November 18, 2010.  Additional legal 
proceedings related to the unauthorized transactions are described in “Item 3. Legal Proceedings” of this Annual Report on Form 10-
K. 

As a result of the unauthorized transactions, the Company restated its previously issued consolidated financial statements and related 
notes thereto for the fiscal year ended June 30, 2009, and for the three month period ended September 30, 2009.  These restatements 
were disclosed in the Company’s Annual Report on Form 10-K/A for the year ended June 30, 2009 and its Quarterly Report on 
Form 10-Q/A for the three months ended September 30, 2009, respectively.  The Company also amended its Quarterly Reports on 
Form 10-Q/A for the three months ended December 31, 2009 and March 31, 2010 to include condensed consolidated financial 
statements and related notes thereto, which were delayed as a result of the restatements.  All of these amended reports were filed on 
June 30, 2010, and should be read in conjunction with this Annual Report on Form 10-K.  The financial effect of the unauthorized 
transactions during fiscal year 2010 is described in “Item 7. Management’s Discussion and Analysis of Financial Condition and 
Results of Operations” and in Note 2 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

ITEM 1.                  BUSINESS. 

GENERAL 

PART I 

As used herein, the term “Company” means Koss Corporation and its consolidated wholly-owned subsidiary, Koss Classics Ltd. 
(“Koss Classics”), unless the context otherwise requires.  The Company was incorporated in Delaware in 1971. 

The Company operates in the audio/video industry segment of the home entertainment industry through its design, manufacture and 
sale of stereo headphones and related accessory products.  The Company reports its results as a single reporting segment, as the 
Company’s principal business line is the design, manufacture and sale of stereo headphones and related accessories. 

The Company’s products are sold through national retailers, international distributors, audio specialty stores, the Internet, direct mail 
catalogs, regional department store chains, discount department stores, military exchanges and prisons under the “Koss” name.  The 
Company also sells products to distributors for resale to school systems, and directly to other manufactures for inclusion with their 
own products.  The Company has more than 250 domestic dealers and its products are carried in approximately 17,000 domestic retail 
outlets and numerous retailers worldwide.  International markets are served by domestic sales representatives and a sales office in 
Switzerland which utilizes independent distributors in several foreign countries.  The Company has one subsidiary, Koss Classics. 

Ninety-nine percent of the Company’s products are stereo headphones for listening to music.  The products are not significantly 
differentiated by their retail sales channel or application with the exception of products sold to school systems and prisons.  There are 
no other product line differentiations other than the quality of the sound produced by the stereo headphone itself, which is highly 
subjective.  The business could also be classified by distribution channel. 

The Company sources complete headphones manufactured to its specifications from various manufacturers in Asia as well as raw 
materials used to produce headphones at its plant in Milwaukee.  Management believes that it has sources of complete headphones and 
raw materials that are adequate for its needs. 

There are no employment or compensation commitments between the Company and its dealers.  The Company has several 
independent manufacturer’s representatives as part of its distribution efforts.  The Company typically signs one year contracts with 
these manufacturer’s representatives.  These agreements are seldom renewed in writing, but continue from year to year.  The 
Company has a manufacturer’s representative agreement with a firm in Detroit to work exclusively in the automotive arena.  The 
automotive representative is paid 2% for all business in this area. The Company’s remaining agreements with distributors, past or 
present, pertain to distribution arrangements in foreign countries.  The arrangements with foreign distributors do not contemplate that 
the Company pays any compensation other than any profit the distributors make upon their sale of the Company’s products.  The 
Company has the right to terminate these agreements with foreign distributors without cause. 

INTELLECTUAL PROPERTY 

John C. Koss is recognized for creating the stereophone industry with the first SP3 stereophone in 1958.  The Company regularly 
applies for registration of its trademarks in many countries around the world in which it does business, and over the years the 
Company has had numerous trademarks registered and patents issued in countries in North America, South America, Asia, Europe, 
Africa, and Australia.  The Company currently has approximately 394 trademarks registered in 87 countries around the world and 
patents in 26 countries.  The Company has trademarks to protect the brand name, Koss, and its logo on its products.  These trademarks 
are maintained throughout the countries in which the Company sells its products.  The Company also holds many design patents that 
protect the unique visual appearance of some of its products.  These trademarks and patents are  

5 

  
  
  
  
  
  
  
  
  
  
  
  
 
Table of Contents 

important to differentiate the Company from its competitors.  Certain of the Company’s trademarks are of material value and 
importance to the conduct of its business.  The Company considers protection of its proprietary developments important; however, the 
Company’s business is not, in the opinion of management, materially dependent upon any single trademark or patent.  During the year 
ended June 30, 2010, the Company took steps to update and monitor its patents and trademarks to protect its intellectual property 
around the world. 

SEASONALITY 

Although retail sales of consumer electronics have typically been higher during the holiday season, stereophones have also seen 
increased interest as gift items over the years.  Management of the Company believes that its business and industry segment are no 
longer seasonal as evidenced by the fact that 59% of net sales occurred in the first six months of the year ended June 30, 2010, and 
41% of net sales occurred in the latter six months of the year.  Management believes that the reason for this level performance of sales 
to retailers is related to the fact that stereo headphones have become replacement items for portable electronic products.  Therefore, 
upgrades and replacements appear to have as much interest over the course of the year as gifts of stereophones during the holiday 
season. 

WORKING CAPITAL AND BACKLOG 

The Company’s working capital needs do not differ substantially from those of its competitors in the industry and generally reflect the 
need to carry significant amounts of inventory to meet delivery requirements of its customers.  From time to time, although rarely, the 
Company may extend payment terms to its dealers for a special promotion.  For instance, the Company has in the past offered a 90-
120 day payment period for certain customers, such as computer retailers and office supply stores.  Based on historical trends, 
management does not expect these practices to have any material effect on net sales or net income.  The Company’s backlog of orders 
as of June 30, 2010 is not considered material in relation to net sales during 2010 or anticipated 2011 net sales. 

CUSTOMERS 

The Company markets a line of products used by consumers to listen to music, DVD’s in vehicles, sound bytes on computer systems, 
and other audio related media.  The Company distributes these products through retail channels in the U.S. and independent 
distributors throughout the rest of the world.  The Company markets its products to approximately 17,000 domestic retailers and 
numerous retailers worldwide.  During 2010, the Company’s sales to its largest single customer, Tura Scandinavia AB, were 
approximately 25% of net sales and sales to Wal-Mart Stores, Inc. accounted for 17% of 2010 net sales.  In 2009, net sales to Tura 
Scandinavia AB and Wal-Mart Stores, Inc, accounted for 17% and 22% of consolidated net sales, respectively.  The Company is 
dependent upon its ability to retain a base of retailers and distributors to sell the Company’s line of products.  Loss of retailers and 
distributors means loss of product placement.  The Company has broad distribution across many channels including specialty stores, 
mass merchants, electronics stores, and computer retailers.  Management believes that any loss of revenues would be partially offset 
by a corresponding decrease, on a percentage basis, in expenses; thereby partially reducing the impact on the Company’s operating 
income.  The five largest customers of the Company (including Tura Scandinavia AB and Wal-Mart Stores, Inc.) accounted for 
approximately 52% and 54% of total net sales in 2010 and 2009, respectively. 

COMPETITION 

The Company focuses on the stereo headphone industry.  In the stereophone market, the Company competes directly with 
approximately five major competitors, several of which are large and diversified and have greater total assets and resources than the 
Company.  The Company’s single product focus is unique in the marketplace.  The extent to which retailers view the Company as an 
innovative vendor of high quality headphone products, and a provider of excellent after sales customer service, is the extent to which 
the Company maintains a competitive advantage.  The Company relies upon its unique sound, quality workmanship, brand 
identification, engineering skills, and customer service to maintain its competitive position.

Table of Contents 

RESEARCH AND DEVELOPMENT 

The amount expensed on engineering and research activities relating to the development of new products or the improvement of 
existing products was approximately $766,000 during 2010 as compared with $1,559,000 during 2009. These activities were 
conducted by both Company personnel and outside consultants.  The Company expects that research and development costs will 
continue and it is planning to introduce a new offering during fiscal year 2011. 

ENVIRONMENTAL MATTERS 

The Company believes that it has materially complied with all currently existing federal, state and local statutes and regulations 
regarding environmental standards and occupational safety and health matters to which it is subject.  During the years 2010 and 2009, 
the amounts incurred in complying with federal, state and local statutes and regulations pertaining to environmental standards and 
occupational safety and health laws and regulations did not materially affect the Company’s operating results or financial condition. 

EMPLOYEES 

As of June 30, 2010, the Company employed 65 people, who are all non-union.  The Company also utilizes temporary personnel. 

FOREIGN SALES 

The Company’s competitive position and risks relating to the conduct of its business in foreign markets are comparable to the 
domestic market.  In addition, the governments of foreign nations may elect to erect trade barriers on imports.  The creation of 
additional barriers would reduce the Company’s net sales and profit.  In addition, any fluctuations in currency exchange rates could 
affect the pricing of the Company’s products and divert customers who might choose to purchase lower-priced, less profitable 
products, and could affect overall demand for the Company’s products.  For further information, see Part II, Item 7 and Note 14 to the 
consolidated financial statements accompanying this Form 10-K. 

The Company has a small sales office in Switzerland to service the international export marketplace.  The Company is not aware of 
any material risks in maintaining this operation.  Loss of this office would result in a transfer of sales and marketing responsibility.  
The Company sells its products to independent distributors in countries and regions outside the United States including Europe, the 
Middle East, Africa, Asia, South America, Latin America, the Caribbean, and Mexico.  The Company sells products in the Canadian 
market through a distributor who services smaller specialty accounts.  During the last two years, net sales of all Koss products, were 
distributed as follows:

In addition to a manufacturing facility in the United States, the Company uses contract manufacturing facilities in the People’s 
Republic of China, Taiwan and South Korea.  These independent supplier entities are distant from the Company, which means that we 
are at risk of business interruptions due to natural disasters, war, disease and government intervention through tariffs or trade 
restrictions that are of less concern domestically.  The Company maintains finished goods inventory in its U.S. facility to mitigate this 
risk.  The Company’s goal is to stock finished goods inventory at an average of approximately 90 days demand per item.  Recovery of 
a single facility through replacement of a supplier in the event of a disaster or suspension of supply could take 120 days.  The 
Company believes that it could restore production of its top ten selling models (which represent approximately 70% of the Company’s 
sales revenue) within one year.  The Company is also at risk if the trade restrictions are

introduced on its products based upon country of origin.  In addition, most increases in tariffs and freight charges would not be 
acceptable to pass along to the Company’s customers and would directly impact the Company’s profits. 

AVAILABLE INFORMATION 

The Company’s internet website is http://www.koss.com.  The Company makes available free of charge through its internet website 
the Company’s annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements and all 
amendments to those reports as soon as reasonably practicable after they are electronically filed with (or furnished to) the SEC.  These 
reports and other information regarding the Company are also available on the SEC’s internet website at http://www.sec.gov. 

ITEM 1A.               RISK FACTORS. 

Investing in the Company’s common stock involves a high degree of risk. Any of the following risks could have a material adverse 
effect on the Company’s financial condition, liquidity and results of operations or prospects, financial or otherwise. 

REDUCTION IN PRESENT LEVELS OF CASH FLOW COULD ADVERSELY AFFECT THE COMPANY’S BUSINESS 

The Company’s primary source of liquidity over the past 12 months has been operating cash flows.  The Company’s future cash flows 
from operations (on both a short term and long term basis) are dependent upon, but not limited to: 

• 
• 
• 
• 
• 
• 

the Company’s ability to attract new customers that will sell the Company’s products and pay for them;
the Company’s ability to retain the Company’s existing customers at the level of sales previously produced;
the volume of sales for these customers;
the loss of business of one or more primary customers;
changes in types of products that the customers purchase in their sales mix;
poor or deteriorating economic conditions which would directly impact the ability of the Company’s customers to 
remain in business and pay for their products on a timely basis;

•  Management’s ability to minimize the impact of requests for increases in material or labor cost increases; and
• 

the ability to collect in full and in a timely manner amounts due to the Company.

In addition, as noted above, the Company’s cash flow is also dependent, to some extent, upon the ability to maintain operating 
margins. The continuing general downturn in economic conditions or other events that caused the Company’s customers to turn to 
lower-priced, lower-margin products, could cause the Company’s cash flow and profitability to be materially and adversely affected. 

FAILURE TO ATTRACT AND RETAIN CUSTOMERS TO SELL THE COMPANY’S PRODUCTS COULD ADVERSELY 
AFFECT SALES VOLUME AND FUTURE PROFITABILITY 

The Company markets a line of products used by consumers to listen to music.  The Company distributes these products through retail 
channels in the U.S. and independent distributors throughout the rest of the world.  The Company is dependent upon its ability to 
retain an existing base of customers to sell the Company’s line of products.  Loss of customers means loss of product placement.  The 
Company has broad distribution across many channels including specialty stores, mass merchants, electronics stores and computer 
retailers.  Any loss of a customer directly translates into a reduction in sales volume which can only be replaced by adding a similar 
number of representative retail outlets.  The inability of the Company’s sales and marketing staff to obtain new distribution outlets 
translates into a lack of future growth and possibly a setback in sales volumes when loss of  

8 

  
  
  
  
  
  
  
  
  
  
  
  
 
Table of Contents 

current customers occur.  For example, the loss of a customer representing 10% of the Company’s business would translate into a 
reduction in revenues of up to 10% based upon the point through the year that the customer was lost.  Attracting a new customer 
during the course of a year could have a positive impact or simply replace an account which has been lost.  In addition, a customer can 
decide to make a change in the models that it decides to offer for sale.  Such changes can occur arbitrarily throughout the course of a 
year which can cause reductions in sales revenues in proportion to the number of retail outlets that the store represents in the market.  
The Company may not be able to maintain customers or model selections and therefore may experience a reduction in its sales 
revenue until a model is restored to the mix or a lost customer is replaced by a new customer.  A reduction in sales volume would 
cause a reduction in profitability.  The Company’s failure to retain existing customers, obtain new customers or develop new product 
lines that customers would choose to offer to consumers could significantly affect the Company’s future profitability.  The loss of 
business of one or more principal customers or a change in the sales volume from a particular customer could have a material adverse 
effect on the Company’s sales volume and profitability. 

SHIFT IN CUSTOMER SPECIFICATIONS TO LOWER PRICED ITEMS CAN REDUCE PROFIT MARGINS 
NEGATIVELY IMPACTING PROFITABILITY 

The Company sells a line of products with a suggested retail price ranging from less than $10 up to $1,000.  The gross margin for each 
of these models is unique in terms of percentages.  The price range of the products also produces a different level of actual dollar 
contribution per unit.  For example, a product with a gross margin contribution of 50% might yield a $5 contribution for one item, 
while another item may feature a 30% gross margin which could yield $50.  The Company finds the low priced portion of the market 
most competitive and therefore most subject to pressure on gross margin percentages, which tends to lower profit contributions.  
Retail preference for lower priced items can reduce profit margins and contributions.  The risk is that a shift in retail customer 
specifications toward lower priced items can lead to lower gross margins and lower profit contributions per unit of sale.  Due to the 
range of products that the Company sells, the product sales mix can produce a variation in terms of a range of profit margins.  Some 
customers sell a limited range of products that yield lower profit margins than others.  Most notably, the budget priced headphone 
segment of the market below $10 retail, which is distributed through computer stores, office supply stores and mass market retailers, 
tends to yield the lowest gross margins.  An increase in business with these types of accounts, if coupled with a simultaneous 
reduction in sales to customers with higher gross margins, would reduce profit margins and profitability. 

POOR ECONOMIC CONDITIONS CAN RESTRICT OR LIMIT PRODUCT PLACEMENT, SALES AND 
REPLENISHMENT WHICH COULD DECREASE PROFITS 

Deteriorating or weak economic conditions, or a forecast for the same, can trigger changes in inventory stocking at retail customers.  
This may in turn lead to a reduction in model offerings and/or out of stock situations.  If a retail customer of the Company does not 
have adequate supply of the Company’s products to offer for sale in a retail store, consumers may choose another competitive model 
instead.  Customers operating retail stores anticipate future sales demands and stock inventory accordingly.  Whenever a general 
economic slowdown occurs, at both the domestic and/or foreign level, sales volume levels and re-order volume levels change.  These 
changes directly impact the Company’s sales and profitability.  The Company is not in a position to determine how it will be affected 
by these circumstances, how extensive the effects may be, or for how long the Company may be impacted by these circumstances.  
The Company’s customers respond to changes in economic conditions and any adverse changes in economic conditions can therefore 
restrict product placement, availability, sales, replenishment and ultimately profitability.  These conditions exist domestically and 
internationally. 

MANAGEMENT IS SUBJECT TO DECISIONS MADE OUTSIDE ITS CONTROL WHICH COULD DIRECTLY AFFECT 
FUTURE PROFITABILITY 

Retail customers determine which products they will stock for resale.  The Company competes with other manufacturers to secure 
shelf space in retail stores for the Company’s products.  During the course of a year, changes in the customers’ management personnel 
can ultimately lead to changes in the stock assortment offered to consumers.  These changes are often arbitrary.  In addition to changes 
in personnel within the Company’s 

9 

  
  
  
  
  
  
  
  
Table of Contents 

customers, it is also possible that a strategic decision can be made by a retail customer to consolidate vendors, or to discontinue certain 
product categories altogether.  In these instances, the Company’s management team may not be able to convince customers to reverse 
such decisions.  The Company’s management team is also engaged in the effective procurement, assembly and manufacture of 
products.  The ability to negotiate with suppliers, maintain productivity and hold the line on cost increases can be subjected to 
pressures outside the control of management.  For example, increases in fuel costs can increase freight rates.  Increases of this nature 
can seldom be avoided and the Company may not be able to pass such increases along to its customers.  Management’s effective 
control of the manufacturing processes will have a direct impact on the Company’s future profitability.  The Company regularly 
makes decisions that affect production schedules, shipping schedules, employee levels and inventory levels.  The Company’s ability to 
make effective decisions in managing these areas has a direct effect on future profitability. 

ACCOUNTS RECEIVABLE AMOUNTS DUE FROM OUR CUSTOMERS CAN BE LOST AS A RESULT OF CUSTOMER 
BANKRUPTCY, OPERATIONAL DIFFICULTY, OR FAILURE TO PAY, NEGATIVELY IMPACTING FUTURE 
PROFITABILITY 

The Company has significant accounts receivable or other amounts due from the Company’s customers.  The outstanding accounts 
receivable, net of allowance for doubtful accounts, at the end of the last four quarters averaged approximately $5,563,000.  Terms of 
payment for customers generally range from cash in advance of delivery to net 120 day credit terms.  These credit arrangements are 
negotiated at unspecified and irregular intervals.  The largest customers generate the largest receivable balances.  If a customer 
develops operational difficulty it is not uncommon to temporarily suspend payment to vendors.  The Company is subject to this risk in 
the retail marketplace.  From time to time a customer may develop severe operating losses which can lead to a bankruptcy.  In these 
cases, the Company may lose most of the outstanding balance due.  Occasionally, the Company has been current with a customer at 
the time such an event occurs.  The more material risk is that of losing the revenue of the customer which might be more onerous than 
losing the current outstanding accounts receivable.  In addition, many companies that will typically insure accounts receivables will 
not do so for the Company’s largest mass market customers.  The risk is that the Company derives most of the Company’s sales 
revenue and profits from selling products to retailers for resale to consumers.  The failure of the Company’s customers to pay in full 
amounts due to the Company could negatively affect future profitability. 

COMPANY PROFITS CAN SUFFER FROM INTERRUPTIONS IN SUPPLY CHAIN 

The Company uses contract manufacturing facilities in the People’s Republic of China, Taiwan and South Korea.  These independent 
suppliers are distant from the Company which means that the Company is at risk of business interruptions due to natural disaster, war, 
disease and government intervention through tariffs or trade restrictions that are of less concern domestically.  Therefore, if there are 
any interruptions in the supply chain for any of these reasons, this could directly impact the Company’s profits in a negative way.  The 
Company is also at risk if trade restrictions are imposed on the Company’s products based upon country of origin.  In addition, any 
increase in tariffs and freight charges may not be acceptable to pass along to the Company’s customers and could directly impact the 
Company’s profits. 

FLUCTUATIONS IN CURRENCY EXCHANGE RATES COULD AFFECT PRICING OF PRODUCTS AND CAUSE 
CUSTOMERS TO PURCHASE LOWER-PRICED, LESS PROFITABLE PRODUCTS AND COULD AFFECT OVERALL 
DEMAND FOR THE COMPANY’S PRODUCTS 

The Company receives a material portion of its sales and profits from business in Europe.  To the extent that the value of the U.S. 
dollar increases relative to currencies in those jurisdictions, it increases the cost of the Company’s products in those jurisdictions, 
which could create negative pressure on the overall demand for the Company’s products.  The Company gets paid by its international 
customers in U.S. dollars.  To the extent that increased prices arising from currency fluctuations decrease the overall demand for the 
Company’s products or motivate customers to purchase lower-priced, lower profit products, the Company’s sales, profits and cash 
flows could be adversely affected.

COMPANY PROFITS CAN SUFFER FROM INCREASING MANUFACTURING COSTS IN CHINA AS A RESULT OF 
INCREASED WAGES AND WAGE TAXES 

The Company uses contract manufacturing facilities in the People’s Republic of China.  An increase in the cost of labor or taxes on 
wages in China may lead to an increase in the cost of goods manufactured in China.  The cost of labor and wage taxes have increased 
in China which means that the Company is at risk of higher manufacturing costs associated with goods manufactured in China.  
Significant increases in wages or wage taxes paid by contract manufacturing facilities may increase the cost of goods manufactured in 
China which could have a material adverse effect on the Company’s profit margins and profitability. 

THE COMPANY USES THIRD PARTY CARRIERS TO SHIP ITS PRODUCTS WHICH MAY PASS ON INCREASES IN 
TRANSPORTATION-RELATED FUEL COST TO THE COMPANY WHICH CAN REDUCE PROFIT MARGINS 
NEGATIVELY IMPACTING PROFITABILITY 

The Company uses numerous third party carriers to ship product, both domestically and internationally.  If the price of fuel increases 
and the carriers choose to pass on the increase to the Company, freight costs may increase.  As a result, the Company’s freight cost is 
impacted by changes in fuel prices.  Fuel prices affect freight costs to both customer’s location and the Company’s distribution center.  
Increases in fuel prices and surcharges and other factors have increased and may continue to increase freight costs in the future.  The 
inflationary pressure of higher fuel costs and continued increase in transportation-related costs could have a material adverse effect on 
the Company’s profit margins and profitability. 

CONSISTENCY OF THE COMPANY’S BUSINESS WITH SEVERAL U.S. RETAILERS 

The Company is particularly concerned about the consistency of business with several U.S. retailers.  The recent tightening of credit 
availability worldwide caused all retailers to sharply curtail inventory increases.  In addition, many retailers have been negatively 
impacted by the economic recession.  The Company has experienced some consolidation in product lines and item elimination, or 
reductions at several big box retailers.  Finally, the Company is subject to fluctuations in production of the Company’s automobile 
customers and the potential impact that might have upon the Company’s rear seat entertainment products for the automotive market in 
the coming year. 

THE COMPANY IS CURRENTLY UNABLE TO ASSESS THE AMOUNTS THAT MAY BE RECOVERED THROUGH 
THE PROCEEDS FROM THE SALE OF ITEMS SEIZED BY LAW ENFORCEMENT, INSURANCE, POTENTIAL 
CLAIMS AGAINST THIRD PARTIES OR TAX REFUNDS. 

The Company has estimated that the amount of the unauthorized transactions is approximately $31,500,000 since fiscal year 2005 
through December 31, 2009 as described in the Company’s Form 10-K/A for June 30, 2009 that was filed on June 30, 2010.  Over 
25,000 items have been seized by law enforcement authorities. Although the Company intends to pursue proceeds from the sale of 
items seized by law enforcement authorities, as well as from insurance coverage, potential claims against third parties and tax refunds, 
the Company cannot reasonably assess the amounts or timing of such recoveries.  Through the date of issuance of this 10-K, the 
Company has received $1,746,469 from its insurance company.  The Company’s inability to recover its losses could have a significant 
and adverse effect on its future financial condition. 

LEGAL PROCEEDINGS RELATED TO THE UNAUTHORIZED TRANSACTIONS MAY ADVERSELY AFFECT THE 
COMPANY’S RESULTS OF OPERATIONS, CASH FLOWS AND FINANCIAL CONDITION. 

As further described in Item 3 Legal Proceedings, the Company is currently addressing several legal matters related to the 
unauthorized transactions. The Company is unable at this time to quantify its exposure, if any.  The costs of dealing with these matters 
and any penalties and awards that may be assessed against the Company could  

11 

  
  
  
  
  
  
  
  
  
  
  
 
Table of Contents 

be substantial and may adversely affect the Company’s future results of operations, cash flows and financial condition. 

THE COMPANY’S STOCK PRICE MAY FLUCTUATE AS A RESULT OF THE UNAUTHORIZED TRANSACTIONS 
AND BECAUSE OF THE UNCERTAINTIES ABOUT THEIR EFFECT ON THE COMPANY’S FINANCIAL CONDITION.

Uncertainties about the effect of the unauthorized transactions and significant developments related to the unauthorized transactions, 
such as the legal matters described above or the results and recommendations of the Independent Investigation could cause fluctuation 
in the Company’s stock price.  The Company’s common stock could also be subject to wide fluctuations in response to additional 
business factors such as the following: 

•                                          the sale or availability for sale of substantial amounts of the Company’s common stock; 

•                                          actual or anticipated fluctuations in the Company’s operating results or its competitors’ operating results; 

•                                          announcements by the Company or its competitors of new products; 

•                                          capacity changes, significant contracts, acquisitions or strategic investments; 

•                                          the Company’s growth rate and its competitors’ growth rates; 

•                                          changes in stock market analyst recommendations regarding the Company, its competitors or the industry in general, 

or lack of analyst coverage of the Company’s common stock; 

•                                          sales of the Company’s common stock by its executive officers, directors and significant stockholders or sales of 

substantial amounts of common stock; and 

•                                          changes in accounting principles. 

THE COMPANY’S INTERNAL CONTROL OVER FINANCIAL REPORTING FAILED TO TIMELY DETECT AND 
PREVENT THE UNAUTHORIZED TRANSACTIONS AND IT IS POSSIBLE THAT WE HAVE NOT IMPLEMENTED 
EFFECTIVE REMEDIAL MEASURES. 

The Company’s internal controls as of June 30, 2009 were not effective in that they failed to timely detect and prevent the 
circumvention of the internal controls and procedures relating to the unauthorized transactions.  Management believes it has 
implemented remedial measures to address the issues identified, but a sufficient amount of time has not yet elapsed to test these 
internal controls and procedures to confirm whether they are effective.  Thus, there is no assurance that these deficiencies have been 
adequately addressed or that the Company has discovered all of the deficiencies that may exist in the internal control over financial 
reporting.  The Independent Investigation is ongoing and it is possible that the Company and/or the Independent Committee may 
identify additional deficiencies regarding the Company’s internal control over financial reporting. 

THE RESTATEMENT OF THE COMPANY’S CONSOLIDATED FINANCIAL STATEMENTS HAS SUBJECTED THE 
COMPANY TO INCREASED COSTS FOR ACCOUNTING AND LEGAL FEES. 

The Company issued restated consolidated financial statements in the Annual Report on Form 10-K/A for June 30, 2009 that was filed 
on June 30, 2010. This restatement was because of errors in previously issued financial statements caused by the unauthorized 
transactions.  This restatement has subjected the Company to significant costs in the form of accounting, legal fees and similar 
professional fees, in addition to the substantial diversion of time and attention of the Company’s Chief Financial Officer and members 
of its accounting department in preparing the restatement.  Although the restatement is complete, no assurance can be given that the 
Company will not incur additional costs associated with the restatement.

ITEM 2.                  PROPERTIES. 

The Company leases its facility in Milwaukee, Wisconsin from its Chairman.  On August 15, 2007, the lease was renewed for a period 
of five years, ending June 30, 2013 and is being accounted for as an operating lease.  The lease extension maintained the rent at a fixed 
rate of $380,000 per year.  The Company is responsible for all property maintenance, insurance, taxes, and other normal expenses 
related to ownership.  All facilities are in good repair and, in the opinion of management, are suitable and adequate for the Company’s 
business purposes. 

ITEM 3.                  LEGAL PROCEEDINGS. 

As of June 30, 2010, the Company is party to the matters related to the unauthorized transactions described below: 

•                                          On January 11, 2010, the Company received a letter from a law firm stating that it represented a shareholder and 

demanding that the Company’s Board of Directors investigate and take legal action against all responsible parties to 
ensure compensation for the Company’s losses stemming from the unauthorized transactions. The Company’s legal 
counsel has responded preliminarily to the letter indicating that the Board of Directors will determine the 
appropriate course of action after the Independent Investigation is completed. 

•                                          On January 15, 2010, a class action complaint was filed in federal court in Wisconsin against the Company, Michael 
Koss and Sujata Sachdeva. The suit alleges violations of Section 10(b), Rule 10b-5 and Section 20(a) of the 
Exchange Act relating to the unauthorized transactions and requests an award of compensatory damages in an 
amount to be proven at trial. See David A. Puskala v. Koss Corporation, et al., United States District Court, Eastern 
District of Wisconsin, Case No. 2:2010cv00041. 

•                                          On January 26, 2010, the SEC’s Division of Enforcement advised the Company that it obtained a formal order of 

investigation in connection with the unauthorized transactions. The Company voluntarily brought the unauthorized 
transactions to the SEC staff’s attention when they were discovered in December 2009, and is cooperating with the 
ongoing SEC investigation. 

•                                          On February 16 and 18, 2010, separate shareholder derivative suits were filed in Milwaukee County Circuit Court in 

connection with the previously disclosed unauthorized transactions. The first suit names as defendants Michael 
Koss, John Koss Sr., the other Koss directors, Sujata Sachdeva, Grant Thornton, LLP, and Koss Corporation (as a 
nominal defendant); the second suit names the same parties except Grant Thornton, LLP. Among other things, both 
suits allege various breaches of fiduciary and other duties, and seek recovery of unspecified damages and other 
relief. See Ruiz v. Koss, et al., Circuit Court, Milwaukee County, Wisconsin, No. 10CV002422 (February 16, 2010) 
and Mentkowski v. Koss, et al., Circuit Court, Milwaukee County, Wisconsin, No. 10CV002290 (February 18, 
2010). These two shareholder derivative suits have been consolidated under Master File No. 10CV002422. 

•                                          On February 18, 2010, the Company filed an action against American Express Company, American Express Travel 

Related Services Company, Inc., AMEX Card Services Company, Decision Science, and Pamela S. Hopkins in 
Superior Court of Maricopa County, Arizona, case no. CV2010-006631, alleging various claims of aiding and 
abetting breach of fiduciary duty, aiding and abetting fraud, conversion, and negligence relating to the unauthorized 
transactions. 

•                                          On June 24, 2010, the Company filed an action against its former independent auditor, Grant Thornton, LLP, and 

Ms. Sachdeva, in Circuit Court of Cook County, Illinois, alleging various claims of accounting malpractice, 
negligent misrepresentation, and fraud relating to the unauthorized transactions.

The Company’s stockholders are entitled to receive dividends as may be declared by the Board of Directors and paid out of funds 
legally available therefore.  The Company began paying dividends for the quarter ended September 30, 2002 and has paid a dividend 
for each quarter since, including the last fiscal quarter ended June 30, 2010.  On May 17, 2010 the Company announced its quarterly 
dividend of $0.06 per share for stockholders of record on June 30, 2010.  The dividend was distributed on or around July 15, 2010.  
Although the Company anticipates it will continue to pay a quarterly dividend, the decision to pay dividends and the amount of such 
dividends are within the sole discretion of the Board of Directors, who meet quarterly.  The decision to pay dividends will depend on 
the Company’s operating results, financial condition, tax considerations, alternative uses for such funds, and other factors the Board of 
Directors deem relevant, and there can be no assurance that dividends will be paid in the future.

increases in the stock repurchase program.  As of June 30, 2010, the most recently approved increase was for additional purchases of 
$2,000,000, which occurred in October of 2006, for an aggregate maximum of $45,500,000, of which $43,360,247 had been expended

ITEM 7.                                              MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 

OPERATIONS. 

The purpose of this discussion and analysis is to enhance the understanding and evaluation of the results of operations, financial 
position, cash flows, indebtedness and other key financial information of the Company for fiscal years 2010 and 2009.  For a more 
complete understanding of this discussion, please read the Notes to Consolidated Financial Statements included in this report. 

Overview 

The Company developed stereo headphones in 1958 and has been a leader in the industry.  We market a complete line of high-fidelity 
stereophones, speaker-phones, computer headsets, telecommunications headsets, active noise canceling stereophones, wireless 
stereophones and compact disc recordings of American Symphony Orchestras on the Koss Classics label. We operate as one business 
segment. 

Unauthorized Transactions — In December 2009, the Company learned of significant unauthorized transactions which totaled 
approximately $31,500,000 from fiscal 2005 through December 2009.  The volume of these unauthorized transactions was $8,498,434 
in 2009, and $10,286,988 from July 1, 2009 until the unauthorized transactions were discovered in December 2009.  As a result of 
these unauthorized transactions, the Company restated its consolidated financial statements on Form 10-K/A for June 30, 2009. 

Operations — Net sales declined to $40,598,722 in 2010 compared with $41,717,114 in 2009.  This $1,118,392 decrease in net sales 
was primarily driven by soft retail sales in the United States and increased promotions with one major customer.  Including the 
unauthorized transactions as an expense, the Company had a loss from operations of $4,955,767 in 2010, compared to a loss from 
operations of $340,094 in 2009.  The increased loss from operations was primarily driven by the increased unauthorized transactions, 
decrease in gross profit from 44.5% to 41.6%, unauthorized transaction related costs and lower sales volume.   In 2010 and 2009, the 
losses related to the unauthorized transactions, exclusive of corrections for accounting errors, were $10,286,988 and $8,498,434, 
respectively, an increase of $1,788,554 in 2010.  The 2010 operating results also included $1,666,986 of unauthorized transaction 
related costs net of recoveries.  Operating income, excluding the unauthorized transactions and related costs and recoveries, was 
$6,998,207 in 2010 or 17.2% of net sales compared to $8,158,340 or 19.6% of net sales in 2009. 

Sales and Gross Profit 

2010 Results of Operations Compared with 2009 

Net sales for 2010 totaled $40,598,722, compared with $41,717,114 in 2009.  This $1,118,392 or 2.7% decrease in net sales was 
driven by soft retail sales in the United States and increased promotions of approximately $700,000 with one major customer in the 
United States.  The decline came in the United States as export sales increased 16.7% from the 2009 level. 

Gross profit in 2010 was $16,868,411 or 41.6% of net sales compared to $18,548,692 or 44.5% of net sales in 2009.  This decreased 
gross margin percentage was driven by increased cost of promotions and increased overhead spending.  The increased cost of 
promotions totaled approximately $700,000 for the agreed period which occurred in advance of significant sales volumes for this 
customer.  The overhead spending increased by approximately $357,000 as a result of spending approximately $169,000 for 
prototypes and engineering tests for products expected to be introduced in fiscal 2011 and for increased fringe benefit costs of 
$87,000.

Selling, General and Administrative Expenses 

Selling, general and administrative expenses for 2010 were $9,870,204, as compared to $10,390,352 for 2009.  The decrease in 
selling, general and administrative expenses was the result of decreased new product research and development activities, not 
participating in a large dealer show and a loss on fixed asset disposals in 2009.  New product development decreased from 
approximately $1,559,000 in 2009 to approximately $766,000 in 2010 due to timing of project phases as we focus on expanding the 
product line in high-end stereo headphones and expand consumers’ listening options with new products.  Spending on new product 
development in 2011 is anticipated to be similar to 2010 levels.  In 2009, the Company participated in the Consumer Electronics Show 
but did not participate in 2010.  Disposals of equipment and leasehold improvements resulted in a loss of approximately $10,000 in 
2010 and $224,000 in 2009. These decreases were partially offset by increased legal fees in support of general corporate activities and 
patent work. 

Unauthorized Transactions 

In 2010, the unauthorized transactions totaled $10,286,988 compared to $8,498,434 in 2009. 

After learning of the unauthorized transactions in December 2009, the Company incurred net cost of $1,666,986 in the second half of 
fiscal 2010.  These net costs related to investigation of the unauthorized transactions, defense of legal actions, restatement of the 
financial statements for the years ended June 30, 2009 and 2008 and the quarter ended September 30, 2009, and issuance of the 
quarterly reports for December 31, 2009 and March 31, 2010.  This net cost was comprised of approximately $3,580,000 of legal and 
professional fees partially offset by approximately $1,913,000 of recoveries.  Included in recoveries is approximately $1,746,000 of 
insurance proceeds. 

Operating Loss 

2010 had an operating loss including the unauthorized transactions of $4,955,767 compared to operating loss of $340,094 in 
2009.  The increased operating loss was primarily driven by the increased unauthorized transactions, unauthorized transaction related 
costs, lower gross profit of 41.6% for 2010 and 44.5% for 2009 and lower sales volume.  Operating income, excluding the 
unauthorized transactions and related costs and recoveries, was $6,998,207 in 2010 or 17.2% of net sales compared to $8,158,340 or 
19.6% of net sales in 2009. 

 Provision for Income Tax Benefit 

Income tax benefit for 2010 was $1,812,417 as compared to $75,434 of income tax benefit in 2009.  The effective income tax rate was 
33.7% in 2010 and 22.7% in 2009.  For 2010, the effective tax rate is driven by changes to the valuation allowance.  The main 
variance in effective tax rate for 2009 compared to the combined federal and state statutory rate of 37% was the impact of permanent 
tax differences in a year that was close to breakeven earnings. 

Operating Activities 

Liquidity and Capital Resources 

We currently use cash generated from operations and underlying working capital as financial measurements to evaluate the 
performance of our operations and our ability to meet our financial obligations.  We require working capital investment to maintain 
our position as a leading developer and manufacturer of high quality stereophones.  The primary drivers of these requirements are 
production costs, distribution costs and finished goods inventories to support our customers’ requirements for short lead time.  As part 
of our continuous improvement of purchasing and manufacturing processes, we continue to strive for alignment of inventory levels 
with customer demand and current production schedules. 

During 2010, cash provided by operations was $982,631, and during 2009, cash provided by operations was $2,646,146.  Working 
capital was $5,371,158 at June 30, 2010 and $6,308,239 at June 30, 2009.  The net decrease

in working capital of $937,081 from June 30, 2009 to June 30, 2010 represents primarily the decrease in cash and cash equivalents and 
increases in accounts payable and accrued liabilities.  The unauthorized transactions in 2010 were funded through cash, delays in 
payments of trade payables and borrowing on the line of credit.  Although significant progress was made since discovery of the 
unauthorized transactions in the latter part of 2010 to pay off some of these outstanding balances, accounts payable and the line of 
credit are still elevated above 2009 levels.  The increase in accrued liabilities was driven by accrued legal fees related to the 
investigation of the unauthorized transactions and the defense of various legal actions. 

Investing Activities 

Cash used in investing activities for 2010 was $1,760,333 as compared to $2,345,298 used in investing activities for 2009.  Cash used 
in investing activities for 2010 was driven by $797,042 of capital expenditures, including tooling to support production, and $639,788 
of product software development expenditures.  In 2009, capital expenditures for tooling and other equipment was $1,018,057 and 
$1,053,738 was spent on product software development expenditures.  Budgeted capital expenditures for equipment and product 
software for year 2011 are approximately $2,500,000.  The Company expects to generate sufficient funds through operations to fund 
these expenditures. 

Financing Activities 

Net cash used in financing activities declined from $1,964,205 in 2009 to $595,678 in 2010.  Dividends paid to stockholders declined 
from $1,920,585 in 2009 to $1,845,678 in 2010.  The Company intends to continue to pay regular quarterly dividends for the 
foreseeable future.  As of June 30, 2010, the Company had net borrowing of $1,250,000 on its line of credit.  On August 31, 2010, the 
Company had net borrowing of $2,800,000 and availability of $5,189,000. 

There were no purchases of common stock in 2010 under the stock repurchase program.  In 2009, the Company purchased $43,620 of 
common stock.  No stock options were exercised in 2010 or 2009. 

Liquidity 

In addition to capital expenditures for tooling and completion of the software development, the Company has interest payments on its 
line of credit, commitments with vendors to reduce the outstanding balance and planned normal quarterly dividend payments. The 
Company believes that cash generated from operations, together with borrowings available under its credit facility, provide it with 
adequate liquidity to meet operating requirements, debt service requirements, accounts payable reduction, planned capital 
expenditures, and dividend payments.  The long-term outlook for the business remains positive, however, the Company continually 
reevaluates new product offerings, inventory levels and capital expenditures to ensure that it is effectively allocating resources in line 
with current market conditions. 

Credit Facilities 

On May 12, 2010, the Company entered into a new secured credit facility with JPMorgan Chase Bank, N.A. (“Lender”).  The Credit 
Agreement dated May 12, 2010 between the Company and the Lender (“Credit Agreement”) provides for an $8,000,000 revolving 
secured credit facility and for letters of credit for the benefit of the Company of up to a sublimit of $2,000,000.  The Credit Agreement 
expires on July 31, 2013.  The Company and the Lender also entered into the Pledge and Security Agreement dated May 12, 2010 
under which the Company granted the Lender a security interest in substantially all of the Company’s assets in connection with the 
Company’s obligations under the Credit Agreement.  The balance on this facility was $1,250,000 as of June 30, 2010.

Stock Repurchase Program 

In April 1995, the Board of Directors approved a stock repurchase program authorizing the Company to purchase from time to time up 
to $2,000,000 of its common stock for its own account.  Subsequently, the Board of Directors periodically has approved increases of 
between $1,000,000 to $5,000,000 in the stock repurchase program.  As of June 30, 2010, the most recently approved increase was for 
additional purchases of $2,000,000, which occurred in October 2006, for an aggregate maximum of $45,500,000, of which 
$43,360,247 had been expended through June 30, 2010.  The Company intends to effect all stock purchases either on the open market 
or through privately negotiated transactions and intends to finance all stock purchases through its own cash flow or by borrowing for 
such purchases. 

There were no stock repurchases under the program in 2010.  During 2009, the Company purchased 7,996 shares of its common stock 
at an average net price of $5.46 per share, for a total purchase price of $43,620.  As of June 30, 2010, the Board of Directors has 
authorized the repurchase by the Company of up to $2,139,753 in Company common stock at the discretion of the Chief Executive 
Officer of the Company.  Future stock purchases under this program are dependent on management’s assessment of value versus 
market price. 

Off-Balance Sheet Arrangements 

The Company has no off-balance sheet arrangements other than the lease for the facility in Milwaukee, Wisconsin, which it leases 
from its Chairman.  On August 15, 2007, the lease was renewed for a period of five years, ending June 30, 2013, and is being 
accounted for as an operating lease.  The lease extension maintained the rent at a fixed rate of $380,000 per year.  The Company is 
responsible for all property maintenance, insurance, taxes and other normal expenses related to ownership.  The facility is in good 
repair and, in the opinion of management, is suitable and adequate for the Company’s business purposes. 

Critical Accounting Policies 

Our discussion and analysis of financial condition and results of operations is based upon our Consolidated Financial Statements, 
which have been prepared in accordance with accounting principles generally accepted in the United States.  The preparation of these 
Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities.  We continually evaluate our estimates and 
judgments, including those related to doubtful accounts, product returns, excess inventories, warranties, impairment of long-lived 
assets, deferred compensation, income taxes and other contingencies.  We base our estimates on historical experience and assumptions 
that we believe to be reasonable under the circumstances.  Actual results may differ from these estimates. 

Revenue Recognition 

The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery 
has occurred; the seller’s price to the buyer is fixed and determinable; and collectibility is reasonably assured.  When these criteria are 
generally satisfied, the Company recognizes revenue.  The Company also offers certain customers the right to return products that do 
not meet the standards agreed with the customer.  The Company continuously monitors such product returns, and while such returns 
have historically been minimal, the Company cannot guarantee that they will continue to experience the same return rates that they 
have experienced in the past.  Any significant increase in product quality failure rates and the resulting credit returns could have a 
material adverse impact on the Company’s operating results for the period or periods in which such returns materialize. 

The Company provides for certain sales incentives.  The Company records a provision for estimated incentives based upon the 
incentives offered to customers on product related sales in the same period as the related revenues are recorded.  The provision is 
recorded as a reduction of sales.  The Company also records a provision for estimated sales returns and allowances on product related 
sales in the same period as the related revenues are  

18 

  
  
  
  
  
  
  
  
  
  
  
 
Table of Contents 

recorded.  These estimates are based on historical sales returns, analysis of credit memo data and other known factors.  If the historical 
data the Company uses to calculate these estimates does not properly reflect future returns, adjustments may be required in future 
periods. 

Accounts Receivable 

The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the 
customer’s current credit worthiness, as determined by the review of the customer’s current credit information.  The Company 
continuously monitors collections and payments from customers and maintains a provision for estimated credit losses based upon the 
Company’s historical experience and any specific customer collection issues that have been identified.  The Company values accounts 
receivable net of an allowance for doubtful accounts.  The allowance is calculated based upon the Company’s evaluation of specific 
customer accounts where the Company has information that the customer may have an inability to meet its financial obligations.  In 
these cases, the Company uses its judgment, based on the best available facts and circumstances and records a specific reserve for that 
customer against amounts due to reduce the receivable to the amount that is expected to be collected.  These specific reserves are re-
evaluated and adjusted as additional information is received that impacts the amount reserved.  However, the ultimate collectability of 
the unsecured receivable is dependent upon the financial condition of an individual customer, which could change rapidly and without 
warning. 

Inventories 

The Company values its inventories at the lower of cost or market.  Cost is determined using the last-in, first-out (“LIFO”) method.  
As of June 30, 2010, 100% of the Company’s inventory was valued using LIFO.  Valuing inventories at the lower of cost or market 
requires the use of estimates and judgment.  The Company continues to use the same techniques to value inventory as have been used 
in the past.  Our customers may cancel their orders or change purchase volumes.  This, or certain additional actions, could create 
excess inventory levels, which would impact the valuation of our inventories.  Any actions taken by our customers that could impact 
the value of our inventory are considered when determining the lower of cost or market valuations.  The Company regularly reviews 
inventory quantities on hand and records a provision for excess and obsolete inventory based primarily on historical usage and 
production requirements.  If the Company is not able to achieve its expectations of the net realizable value of the inventory at its 
current value, the Company would have to adjust its reserves accordingly. 

Product Software Development Costs 

Product software development costs consist of costs incurred by outside parties for the development of software used to support new 
products.  These assets have been evaluated to ensure that the capitalized costs do not exceed the estimated net realizable value of the 
related products.  As part of the impairment analysis, we use a discounted cash flow model based on estimated sales to be derived in 
the future use of the asset and other estimated costs directly related to the product.   No amortization was recorded in 2010 or 2009 as 
the related products have not yet been introduced.  The Company expects the products to be introduced during fiscal year 2011. 

The discounted cash flow model involves many assumptions, including operating results forecasts and discount rates.  Inherent in the 
operating results forecasts are certain assumptions regarding revenue growth rates, projected cost saving initiatives and projected long-
term growth rates.  The Company performed impairment testing as of June 30, 2010 and 2009 and no impairment was identified. 

Product Warranty Obligations 

Products sold are generally covered by a lifetime warranty.  We record accruals for potential warranty claims based on prior product 
returns experience.  Warranty costs are accrued at the time revenue is recognized.  These warranty costs are based upon management’s 
assessment of past claims and current experience.  However, actual claims could be higher or lower than amounts estimated, as the 
amount and value of warranty claims are subject to variation as a result of many factors that cannot be predicted with certainty.

Income Taxes 

We estimate the effective tax rate expected to be applicable for the full fiscal year.  If the actual results are different from these 
estimates, adjustments to the effective tax rate may be required in the period such determination is made.  Additionally, discrete items 
are treated separately from the effective rate analysis and are recorded separately as an income tax provision or benefit at the time they 
are recognized. 

Deferred income taxes are accounted for under the asset and liability method whereby deferred income tax assets and liabilities are 
recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing 
assets and liabilities and their respective tax bases.  Deferred income tax assets and liabilities are measured using statutory tax 
rates.  Deferred income tax provisions are based on changes in the deferred tax assets and liabilities from period to period.  
Additionally, we analyze our ability to recognize the net deferred income tax assets created in each jurisdiction in which we operate to 
determine if valuation allowances are necessary based on the “more likely than not” criteria.

ITEM 9A.               CONTROLS AND PROCEDURES. 

Disclosure Controls and Procedures. 

Disclosure controls and procedures (as defined in Rules 13(a)-15(e) and 15(d)-15(e)) of the Securities Exchange Act of 1934, as 
amended (the “Exchange Act”) are designed to ensure that (1) information required to be disclosed in reports filed or submitted under 
the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and (2) 
that such information is accumulated and communicated to management, including the principal executive officer and principal 
financial officer, to allow timely decisions regarding required disclosures.  There are inherent limitations to the effectiveness of any 
system of disclosure controls and procedures, including the possibility of human error, the circumvention or overriding of controls and 
procedures and collusion to circumvent and conceal the overriding of controls and procedures.  Accordingly, even effective disclosure 
controls and procedures can only provide reasonable assurance of achieving their control objectives. 

The Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the 
effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 30, 2010.  As discussed in 
“Changes in Internal Controls” below, the Company recently implemented remedial measures in response to the previously disclosed 
unauthorized transactions. Although the Company’s management believes that these remedial measures have addressed the 
weaknesses in the Company’s disclosure controls and procedures, the Company must allow a sufficient amount of time to elapse to 
permit testing of these controls in order to confirm their effectiveness.  Subject to this testing and confirmation process, management 
believes that the Company’s disclosure controls and procedures will be deemed effective.

Table of Contents 

The Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, continues to evaluate the 
effectiveness of the Company’s disclosure controls and procedures to identify any additional enhancements that may provide greater 
comfort that the Company’s disclosure controls and procedures are effective to provide reasonable assurance that information required 
to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the 
Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions 
regarding required disclosure and are effective to provide reasonable assurance that such information is recorded, processed, 
summarized and reported within the time periods specified in the SEC’s rules and forms. 

Management’s Annual Report on Internal Controls over Financial Reporting. 

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, is responsible for establishing and 
maintaining adequate internal control of financial reporting (as defined in Exchange Act Rules 13(a)-15(f) and 15(d)-15(f)) and 
designing such internal controls to provide reasonable assurances regarding the reliability of financial reporting and the preparation of 
financial statements for external purposes in accordance with accounting principles generally accepted in the United States of 
America.  Because of inherent limitations, a system of 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 due to change in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Management conducted its evaluation of the effectiveness of its internal control over financial reporting based on the framework in 
“Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(“COSO”).  Based on this assessment, the Company’s management, including its Chief Executive Officer and Chief Financial Officer, 
has concluded that the Company’s internal controls and operating procedures were circumvented during the fiscal year and the 
circumvention was concealed from management as previously described in the Form 10-K/A for June 30, 2009.  The Company has 
already implemented the internal control improvements described in Changes in Internal Controls below, and the Company is 
planning to implement a new computer system towards the end of fiscal year 2011 that will further enhance the segregation of duties 
within information technology.  Based on the criteria set forth by COSO in “Internal Control-Integrated Framework,” although the 
Company’s management believes that these enhancements and remedial measures have addressed the weaknesses in the Company’s 
disclosure controls and procedures, the Company must allow a sufficient amount of time to elapse to permit testing of these controls in 
order to confirm their effectiveness.  Subject to this testing and confirmation process, management believes that the Company’s 
disclosure controls and procedures will be deemed effective. 

Changes in Internal Controls 

The Company has identified how its controls over financial reporting were circumvented and how it is addressing these matters below.

•                        Auditor review.  The circumvention of the Company’s internal controls and procedures was not detected as part of the 

Company’s annual audits and quarterly reviews by its former independent auditor, Grant Thornton, LLP.  As described in 
Item 3 Legal Proceedings, on June 24, 2010, the Company filed an action against Grant Thornton, LLP and Ms. Sachdeva. 

•                        Wire transfers and cashier’s checks.  Approximately $30,900,000 or 98.1% of the total $31,500,000 of unauthorized 

transactions from fiscal year 2005 through December 2009 was misappropriated by circumventing the Company’s internal 
controls and other operating procedures for the payment of Company expenditures by using wire transfers or cashier’s 
checks from the Company’s bank accounts to pay for personal expenditures.  Of the $30,900,000, approximately 
$8,500,000 was misappropriated by use of these means during 2009.  Misappropriations by use of wire transfers or 
cashier’s checks totaled $10,300,000 during 2010.  These unauthorized transactions were processed by circumventing the 
Company’s policy that all invoices over $5,000 were required to be submitted and approved by  

21 

  
  
  
  
  
  
  
  
  
 
Table of Contents 

Michael Koss as the CEO, and all accounts payable checks generated from the Company’s accounts payable system were 
signed by the CEO.  Moreover, wire transfers were to be used only for authorized transactions including certain inventory 
purchases and transfers of funds between the Company’s bank accounts.  Wire transfers for inventory purchases and the 
recurring expense items required the approval by several employees including authorized Vice Presidents, while the wire 
transfers between the Company’s bank accounts were processed and approved by Ms. Sachdeva and one of the other 
terminated employees in the accounting department.  Ms. Sachdeva, by herself and/or by directing other employees in the 
accounting department, ordered cashier’s checks from the Company’s bank accounts to pay for personal expenditures 
directly, thereby circumventing the internal controls and procedures as described above so that these payments would not 
be submitted through the Company’s normal accounts payable system.  Ms. Sachdeva, by herself and/or by directing others 
in the accounting department, processed wire transfers from the Company’s bank accounts to pay for personal expenditures 
directly, thereby circumventing the internal controls and procedures as described above so that these payments would not 
be submitted through the Company’s normal accounts payable system.  This has been remediated by: (1) disallowing the 
use of any cashier’s checks; (2) enforcing that all wire transfers are initiated within the financial function and electronically 
approved by the CEO; and (3) performing an enhanced review, reconciliation and reporting of cash activities. 

•                        Petty cash, manual checks and traveler’s checks.  The remaining misappropriations of approximately $600,000 or 1.9% 

from the total amount of $31,500,000 from fiscal year 2005 through December 2009 were carried out by circumventing the 
Company’s internal controls and other standard operating procedures involving the Company’s petty cash system, manual 
check system and policy for using traveler’s checks.  In doing so, the Company’s policy requiring that all expense reports 
be submitted and approved by the CEO was circumvented.  Out of the estimated $600,000 of these types of transactions, 
approximately $91,000 occurred during 2009.  Approximately $107,000 of misappropriations involving the use of the 
Company’s petty cash system, manual check system and traveler’s checks policy occurred during 2010.  Remediation of 
these issues has been accomplished by: (1) eliminating the petty cash fund so all reimbursements run through normal 
controlled accounts payable channels; (2) eliminating the use of manual checks so all check disbursements are generated 
from the Company’s accounts payable system check run; and (3) eliminating the use of traveler’s checks. 

•                        Recording of unauthorized transactions.  Ms. Sachdeva and one of the other terminated employees concealed the 

unauthorized transactions by recording numerous erroneous accounting entries in various accounts to hide the true nature 
of the transactions.  The Company has improved the controls and procedures related to journal entries and account 
reconciliations to include improved segregation of duties, review and approval of reconciliations, and approval of all 
manual journal entries. 

•                        Performance and review of account reconciliations.  The Company’s internal controls and procedures included the 

performance and review of key account reconciliations, including cash, by the accounting department employees including 
Ms. Sachdeva, who collectively had over 50 years of experience at the Company.  Ms. Sachdeva and one of the other 
terminated employees further concealed the unauthorized transactions by failing to properly perform and review these key 
account reconciliations on a regular basis, and failing to properly perform the Company’s period end financial close and 
reporting processes that were designed to accurately report the Company’s financial information.  The account 
reconciliation process has been improved and includes proper segregation of duties as well as review and approval by 
another person in the financial function. 

•                        Corporate standards and whistleblower policy.  The three terminated employees, including Ms. Sachdeva, failed to comply 

with the Company’s established standards of integrity, ethical values and its Code of Conduct, Code of Ethics and 
Whistleblower policy.  The Company has taken steps to reinforce these policies with all of its employees, officers and 
directors. 

22 

  
  
  
  
  
  
 
Table of Contents 

•                        Application of GAAP.  The terminated employees, including Ms. Sachdeva, as the principal accounting officer in charge of 
financial reporting failed to properly apply the Company’s established accounting policies and adherence with GAAP.  As 
a result, certain established accounting policies were not applied correctly and resulted in inaccuracies, both from the 
fraudulent activity directed by Ms. Sachdeva and the misapplication of GAAP.  The affected accounts include equipment 
and leasehold improvements, cash surrender value of life insurance, accrued deferred compensation, accrued product 
warranty obligations and income taxes payable.  As part of the restatement of the consolidated financial statements, the 
accounts were reviewed in detail and reconciled.  Integral to the reconciliation process was a review of all critical 
accounting estimates. 

•                        Information Technology.  The Company’s internal controls and procedures relating to the Company’s computer system for 
processing financial transactions were manipulated to conceal the unauthorized transactions.  The Company expects to 
implement a new computer system that will be used to improve its processing of financial transactions and overall 
segregation of duties towards the end of fiscal 2011. 

We believe the changes to our system of internal controls resulting from these efforts have enhanced the Company’s control over 
financial reporting.  We continue to diligently and vigorously review our financial and reporting controls and procedures.  As we 
continue to evaluate and work to improve our internal control over financial reporting, we may take additional measures to address 
any additional control deficiencies we may identify.

To the Board of Directors 
Koss Corporation 
Milwaukee, Wisconsin 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

We have audited the accompanying consolidated balance sheets of Koss Corporation and Subsidiary (the “Company”) as of June 30, 
2010 and 2009, the related consolidated statements of operations, stockholders’ equity and cash flows for the years then ended. These 
consolidated financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on 
these consolidated financial statements 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 audit to obtain reasonable assurance about whether the consolidated financial 
statements are free of material misstatement.  The Company is not required to have, nor were we engaged to perform, an audit of its 
internal control over financial reporting.  Our audits included consideration of its internal control over financial reporting as a basis for 
designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the 
effectiveness of the Company’s internal control over financial reporting.  Accordingly, we express no such opinion.  An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements.  An audit also 
includes assessing the accounting principles used and significant estimates made by management as well as evaluating the overall 
consolidated financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of 
Koss Corporation and Subsidiary as of June 30, 2010 and 2009 and the results of their operations and their cash flows for the years 
then ended, in conformity with U.S. generally accepted accounting principles. 

As discussed in Note 16 to the consolidated financial statements, the Company has been named in several legal matters.  In addition, 
the Company has also initiated certain legal actions against third parties.

KOSS CORPORATION AND SUBSIDIARY 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.                                      ACCOUNTING POLICIES 

NATURE OF BUSINESS — Koss Corporation (“Koss”) and its wholly-owned subsidiary (collectively the “Company”), a Delaware 
Corporation, reports its finances as a single reporting segment, as the Company’s principal business line is the design, manufacture 
and sale of stereo headphones and related accessories.  The Company leases its plant and office in Milwaukee, Wisconsin.  In 
addition, the Company has more than 250 domestic dealers and its products are carried by approximately 17,000 domestic retailers 
and numerous retailers worldwide.  International markets are served by domestic sales representatives and a sales office in 
Switzerland which utilizes independent distributors in several foreign countries.  The Company has one subsidiary, Koss Classics Ltd. 
(“Koss Classics”). 

BASIS OF CONSOLIDATION — The consolidated financial statements include the accounts of Koss and its subsidiary, Koss 
Classics, which is a wholly-owned subsidiary.  All significant intercompany accounts and transactions have been eliminated. 

STOCK SPLIT —  On September 10, 2009, NASDAQ notified the Company that it no longer met the minimum 750,000 publicly 
held shares requirement under Listing Rule 5450(b)(1)(B). The Company remedied its noncompliance with Listing Rule 5450(b)(1)
(B) by implementing a two-for-one forward stock split on December 1, 2009.  All share and per-share data have been adjusted 
retroactively to give effect to the stock split. 

CONCENTRATION OF CREDIT RISK — The Company operates in the audio/video industry segment of the home entertainment 
industry through its design, manufacture and sale of stereo headphones and related accessory products.  The Company’s products are 
sold through national retailers, international distributors, audio specialty stores, the Internet, direct mail catalogs, regional department 
store chains and military exchanges under the “Koss” name and dual label.  The Company grants unsecured credit to its domestic and 
international customers based on the extension of credit from 30 to 120 days, depending on the customer.  Collection is dependent on 
the retailing industry economy.  The vast majority of international customers, outside of Canada, are sold on a cash against documents 
or cash in advance basis.  Approximately 20% and 14% of the Company’s accounts receivable at June 30, 2010 and 2009, 
respectively, were foreign receivables denominated in U.S. dollars. 

REVENUE RECOGNITION — Revenue is recognized by the Company when all of the following criteria are met:  persuasive 
evidence of an arrangement exists; delivery has occurred; the seller’s price to the buyer is fixed and determinable; and collectibility is 
reasonably assured.  These criteria are generally satisfied upon shipment of the Company’s products.  The Company may periodically 
offer slotting fees, cooperative advertising programs, rebates and sales discounts and the estimated costs for these items are accrued 
for at the time revenue is recognized.  These amounts are recorded as a reduction to sales. 

ROYALTY INCOME — The Company recognizes royalty income when earned under the terms of its license agreements.  
Historically, royalty payments were calculated based upon predetermined percentages of net sales of the licensed products or based 
upon minimum quarterly royalty payments, as set forth in the Company’s license agreements.  Royalty income is booked monthly, on 
an accrual basis, and the amount that the Company accrues is the monthly equivalent of the minimum royalty payment.  When the 
royalty payments are received each quarter, the Company then applies the payment to accounts receivable accordingly.  In 2009, the 
Company had one license agreement that terminated in the fourth quarter of 2009.  As of June 30, 2010 the Company had no license 
agreements in effect that would provide for royalty income. 

SHIPPING AND HANDLING FEES AND COSTS — Shipping and handling fees are included in cost of goods sold within the 
accompanying consolidated statements of operations. 

RESEARCH AND DEVELOPMENT — Research and development activities charged to operations amounted to approximately 
$766,000, in 2010 and $1,559,000 in 2009.

Table of Contents 

ADVERTISING COSTS — Advertising costs included within selling, general and administrative expenses in the accompanying 
consolidated statements of operations were approximately $57,000 in 2010 and $130,000 in 2009.  Such costs are expensed as 
incurred. 

INCOME TAXES — The Company operates as a C Corporation under the Internal Revenue Code of 1986, as amended (the “Code”).  
Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily 
represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences 
between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future 
based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. As 
changes in tax laws or rates are enacted, deferred income tax assets and liabilities are adjusted through the provision for income taxes. 
The differences relate principally to different methods used for depreciation for income tax purposes, net operating losses, 
capitalization requirements of the Code, allowances for doubtful accounts and inventory valuation methods, unauthorized transactions, 
warranty reserves, and other income tax related carryforwards. Valuation allowances are established when necessary to reduce 
deferred income tax assets to the amount expected to be realized. 

EARNINGS (LOSS) PER COMMON SHARE — Earnings (loss) per common share is calculated under the provisions of Topic 260 
in the Accounting Standards Codification which provides for calculation of “basic” and “diluted” earnings per share.  Basic earnings 
(loss) per common share includes no dilution and is computed by dividing net income (loss) by the weighted average common shares 
outstanding for the period.  Diluted earnings (loss) per common share reflect the potential dilution of securities that could share in the 
earnings of an entity. 

CASH AND CASH EQUIVALENTS — The Company considers depository accounts and investments with a maturity at the date of 
acquisition and expected usage of three months or less to be cash and cash equivalents.  The Company maintains its cash on deposit at 
commercial banks located in the United States of America.  The Company periodically has cash balances in excess of insured 
amounts.  The Company has not experienced and does not expect to incur any losses on these deposits. 

ACCOUNTS RECEIVABLE — Accounts receivable consists of unsecured trade receivables due from customers.  The Company 
performs credit evaluations of its customers and does not require collateral to establish an account receivable.  The Company evaluates 
collectibility of accounts receivable based on a number of factors.  Accounts receivable are considered to be past due if unpaid one 
day after their due date.  An allowance for doubtful accounts is recorded for significant past due receivable balances based on a review 
of the past due item, general economic conditions and the industry as a whole.  The Company writes off accounts receivable when 
they become uncollectible.  There were no recoveries of previously written-off accounts receivable during 2010 or 2009.  Changes in 
the allowance for doubtful accounts are as follows:

INVENTORIES — As of June 30, 2010 and 2009, 100% of the Company’s inventory was valued at the lower of last-in, first-out 
(“LIFO”) cost or market.  If the first-in, first-out (“FIFO”) method of inventory accounting had been used by the Company for 
inventories valued at LIFO, inventories would have been $793,972 and $776,307 higher than reported at June 30, 2010 and 2009, 
respectively.  The Company did not maintain any work-in-process inventories at June 30, 2010 and 2009.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS — Equipment and leasehold improvements are stated at cost.  Depreciation 
and amortization is provided using the straight-line method over the estimated useful lives of the respective assets.  Leasehold 
improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the asset.  
Major expenditures for property and equipment and significant renewals are capitalized.  Maintenance, repairs and minor renewals are 
expensed as incurred.  When assets are retired or otherwise disposed of, their costs and related accumulated depreciation and 
amortization are removed from the accounts and any resulting gains or losses are included in operations. 

PRODUCT SOFTWARE DEVELOPMENT COSTS — The Company follows the guidance of ASC 985-20 “Costs of Software to be 
Sold, Leased, or Marketed” when capitalizing development costs associated with software to be incorporated into its products.  The 
cost of purchased software technology is capitalized and stated at the lower of unamortized cost or expected net realizable value.  
Software is subject to rapid technological obsolescence and future revenue estimates supporting the capitalized software cost can be 
negatively affected based upon competitive products, services and pricing.  Such adverse developments could reduce the estimated net 
realizable value of our product software development costs and could result in impairment or a shorter estimated life.  Such events 
would require us to take a charge in the period in which the event occurs or to increase the amortization expense in future periods and 
would have a negative effect on our results of operations. At a minimum, we review for impairments each balance sheet date.  The 
Company expects to launch the related products and begin amortization in 2011. 

LIFE INSURANCE POLICIES — The Company carries its cash surrender value of life insurance at values stated by the insurance 
carriers, reduced by the value of outstanding policy loans made to the insured, or at the amount the Company would receive in the 
case of split-dollar arrangements.  Increases in cash surrender value are included in other income in the Consolidated Statements of 
Operations.  The carrying value of cash surrender value of life insurance has been reduced by $61,157 of policy loans at June 30, 2010 
and 2009. 

INVESTMENTS — Included in “Other Assets” at June 30, 2009 is $25,000 of Israel government bonds which matured in July 2009.  
Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity.  
Held-to-maturity securities are stated at cost, adjusted for amortization of premiums and discounts to maturity. 

PRODUCT WARRANTY OBLIGATIONS — Estimated future warranty costs related to products are charged to cost of goods sold 
during the period the related revenue is recognized. The product warranty liability reflects the Company’s best estimate of probable 
obligations under those warranties. As of June 30, 2010 and 2009, the Company has recorded a warranty reserve of $1,017,450 and 
$1,087,000, respectively.  (See Note 11) 

DEFERRED COMPENSATION — The Company’s deferred compensation liabilities are for a current and former officer and are 
calculated based on compensation, years of service and mortality tables.  The related expense is included in selling, general and 
administrative expenses in the Consolidated Statements of Operations. 

FAIR VALUE OF FINANCIAL INSTRUMENTS — Cash and cash equivalents, accounts receivable and accounts payable 
approximate fair value based on the short maturity of these instruments. 

IMPAIRMENT OF LONG-LIVED ASSETS — The Company evaluates the recoverability of the carrying amount of long-lived assets 
whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable.  The 
Company evaluates the recoverability of equipment and leasehold improvements and product software development costs annually or 
more frequently if events or circumstances

Table of Contents 

indicate that an asset might be impaired.  If an asset is considered to be impaired, the impairment to be recognized is measured as the 
amount by which the carrying amount of the asset exceeds its fair value.  Assets to be disposed of are reported at the lower of the 
carrying amount or fair value less cost to sell.  Management determines fair value using discounted future cash flow analysis or other 
accepted valuation techniques.  Management believes that there has not been any impairment of the Company’s long-lived assets as of 
June 30, 2010 and 2009. 

LEGAL COSTS — All legal costs related to litigation are charged to operations as incurred except settlements, which are expensed 
when a claim is probable and can be estimated.  Recoveries of legal costs are recorded when the amount and items to be paid are 
confirmed by the insurance company. 

STOCK-BASED COMPENSATION — The Company has a stock-based employee compensation plan, which is described more fully 
in Note 6.  The Company accounts for stock-based compensation in accordance with ASC 718.  Under the fair value recognition 
provisions of this statement, share-based compensation cost is measured at the grant date based on the fair value of the award and is 
recognized as expense over the vesting period.  Determining the fair value of share-based awards at the grant date requires judgment, 
including estimating future volatility of the Company’s stock, the amount of share-based awards that are expected to be forfeited and 
the expected term of awards granted.  The Company estimates the fair value of stock options granted using the Black-Scholes option 
valuation model.  The fair value of all awards is amortized on a straight-line basis over the vesting periods.  The expected term of 
awards granted represent the period of time they are expected to be outstanding.  The Company determines the expected term based on 
historical experience with similar awards, giving consideration to the contractual terms and vesting schedules.  The Company 
estimates the expected volatility of its common stock at the date of grant based on the historical volatility of its common stock.  The 
volatility factor used in the Black-Scholes option valuation model is based on the Company’s historical stock prices over the most 
recent period commensurate with the estimated expected term of the awards.  The risk-free interest rate used in the Black-Scholes 
option valuation model is based on the implied yield currently available on U.S. Treasury zero-coupon issues with a remaining term 
commensurate with the expected term of the awards.  Pre-vesting option forfeitures are estimated using historical actual forfeitures.  
Stock-based compensation is recorded only for those options expected to vest.  If actual results differ significantly from these 
estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted. 

USE OF ESTIMATES — The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and 
liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported 
amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates. 

RECLASSIFICATIONS — Certain amounts previously reported have been reclassified to conform to the current presentation. 

2.             UNAUTHORIZED TRANSACTIONS 

In December 2009, the Company learned of significant unauthorized transactions, which totaled approximately $31,500,000 from 
fiscal 2005 through December 2009.  The volume of these unauthorized transactions was $8,498,434 in fiscal year 2009 and 
$10,286,988 from July 1, 2009 until the unauthorized transactions were discovered in December 2009.  As a result of these 
unauthorized transactions, the Company restated its consolidated financial statements on Form 10-K/A for June 30, 2009. 

The unauthorized transactions line in the Consolidated Statements of Operations represents the total of identified unauthorized 
transactions in those years.

4.             EARNINGS (LOSS) PER COMMON AND COMMON EQUIVALENT SHARE 

Basic earnings (loss) per share are computed based on the weighted-average number of common shares outstanding.  The weighted-
average number of common shares outstanding for the years ended June 30, 2010 and 2009 were 7,382,706 and 7,386,250, 
respectively.  When dilutive, stock options are included in earnings per share as share equivalents using the treasury stock method.  
For the years ended June 30, 2010 and 2009 there were no common stock equivalents related to stock option grants that were included 
in the computation of the weighted-average number of shares outstanding for diluted loss per share.  Shares under option of 1,159,308 
and 863,308 were excluded from the diluted weighted average common shares outstanding for the years ended June 30, 2010 and 
2009 as they would be anti-dilutive due to the Company’s net loss for the year. 

5.                                      CREDIT FACILITIES 

On February 16, 2009, the Company entered into a credit facility with Harris N.A. for an unsecured line of credit for up to a maximum 
of $10,000,000 up to and including January 29, 2010.  On October 9, 2009 the credit facility was extended to December 31, 2010.  
The credit facility replaced the Company’s previous credit facility, which was terminated and contained substantially the same terms 
as the Company’s new credit facility.    The Company could use the credit facility for working capital, to refinance existing 
indebtedness, for stock repurchase and for general corporate purposes.  Borrowings under the credit facility bore interest at either the 
bank’s most recently publicly announced prime rate or at a London Interbank Offered Rate (“LIBOR”) based rate plus 1.25% as 
determined in accordance with the loan agreement. The credit facility included certain financial covenants that required the Company 
to maintain a minimum tangible net worth, liabilities to tangible net worth ratios and interest coverage ratios.  The Company used its 
credit facility from time to time, although there was no utilization of this credit facility at June 30, 2009.  The Company’s credit 
facility with Harris N.A. was terminated on May 12, 2010 and the outstanding balance of $5,863,349 as of that date was fully repaid. 

On May 12, 2010, the Company entered into a new secured credit facility with JPMorgan Chase Bank, N.A. (“Lender”).  The Credit 
Agreement dated May 12, 2010 between the Company and the Lender (“Credit Agreement”) provides for an $8,000,000 revolving 
secured credit facility with interest rates either ranging from 0.0% to 0.75% over the Lender’s most recently publicly announced prime 
rate or 2.0% to 3.0% over LIBOR, depending on the Company’s leverage ratio.  The Credit Agreement expires on July 31, 2013. In 
addition to the revolving loans, the Credit Agreement also provides that the Company may, from time to time, request the Lender to 
issue letters of credit for the benefit of the Company of up to a sublimit of $2,000,000 and subject to certain other limitations.  The 
loans may be used only for general corporate purposes of the Company. 

The Credit Agreement contains certain affirmative, negative and financial covenants customary for financings of this type.  The 
negative covenants include restrictions on other indebtedness, liens, fundamental changes, certain investments, asset sales, sale and 
leaseback transactions and transactions with affiliates, among other restrictions.  The financial covenants include a minimum current 
ratio, minimum tangible net worth and maximum leverage ratio requirements.  The Company and the Lender also entered into the 
Pledge and Security Agreement dated May 12, 2010 under which the Company granted the Lender a security interest in substantially 
all of the Company’s assets in connection with the Company’s obligations under the Credit Agreement.  At June 30, 2010, the 
outstanding balance on this credit facility was $1,250,000.  The applicable interest rates at June 30, 2010 were 2.84% on $1,000,000 of 
outstanding balance and 3.75% on $250,000 of outstanding balance.  The weighted average interest rate in effect in the borrowings 
outstanding as of June 30, 2010 was 3.02%. 

6.                                      STOCK OPTIONS 

In 1990, pursuant to the recommendation of the Board of Directors, the stockholders ratified the creation of the Company’s 1990 
Flexible Incentive Plan (the “1990 Plan”).  The 1990 Plan is administered by a committee of the Board of Directors and provides for 
granting of various stock-based awards including stock options to eligible participants, primarily officers and certain key employees.  
A total of 225,000 shares of common stock were available in the first year of the 1990 Plan’s existence.  Each year thereafter 
additional shares equal to 0.25% of the shares outstanding as of the first day of the applicable fiscal year were reserved for issuance 
pursuant to the  

35 

  
  
  
  
  
  
  
  
  
 
Table of Contents 

1990 Plan.  On July 22, 1992, the Board of Directors authorized the reservation of an additional 250,000 shares for the 1990 Plan, 
which was approved by the stockholders.  In 1993, the Board of Directors authorized the reservation of an additional 300,000 shares 
for the 1990 Plan, which was approved by the stockholders.  In 1997, the Board of Directors authorized the reservation of an 
additional 300,000 shares for the 1990 Plan, which was approved by the stockholders.  In 2001, the Board of Directors authorized the 
reservation of an additional 300,000 shares for the 1990 Plan, which was also approved by the stockholders.  As of June 30, 2010, 
there are 485,506 options available for future grants.  Options vest over a four or five year period from the date of grant, with a 
maximum term of five to ten years. 

The fair value of each stock option grant was estimated as of the date of grant using the Black-Scholes pricing model.  The resulting 
compensation cost for fixed awards with graded vesting schedules is amortized on a straight-line basis over the vesting period for the 
entire award.  The expected term of awards granted is determined based on historical experience with similar awards, giving 
consideration to the expected term and vesting schedules.  The expected volatility is determined based on the Company’s historical 
stock prices over the most recent period commensurate with the expected term of the award.  The risk-free interest rate is based on 
U.S. Treasury zero-coupon issues with a remaining term commensurate with the expected term of the award.  Expected pre-vesting 
option forfeitures are based on historical data. 

As of June 30, 2010, there was approximately $706,000 of total unrecognized compensation cost related to stock options granted 
under the 1990 Plan.  This cost is expected to be recognized over a weighted average period of 2.87 years.  Total unrecognized 
compensation cost will be adjusted for any future changes in estimated and actual forfeitures.   The Company recognized stock-based 
compensation expense of $435,121 and $442,660 in 2010 and 2009, respectively.  These expenses were included in selling, general 
and administrative expenses. 

There was no cash received from stock option exercises during 2010 or 2009. 

The per share weighted average fair value of the stock options granted during the year ended June 30, 2010 was $1.49.  The fair value 
of each option granted is estimated on the date of grant using the Black-Scholes option-pricing model.  There were no options granted 
in 2009.  For the options granted in 2010, the Company used the following weighted-average assumptions: 

Expected stock price volatility 
Risk free interest rate 
Expected dividend yield 
Expected forfeitures 
Expected life of options

Total options of 390,000 were granted during the year ended June 30, 2010 at a price equal to or greater than the market value of the 
common stock on the date of grant. These options had a weighted-average exercise price of $6.39.  No options were granted during 
the year ended June 30, 2009. 

7.             STOCK PURCHASE AGREEMENTS 

The Company has an agreement with its Chairman, John C. Koss, in the event of his death, at the request of the executor of his estate, 
to repurchase his Company common stock from his estate.  The Company does not have the right to require the estate to sell stock to 
the Company.  As such, this arrangement is accounted for as a written put option with the fair value of the put option recorded as a 
derivative liability. 

The fair value of the written put option at both June 30, 2010 and 2009 was $125,000.  The repurchase price is 95% of the fair market 
value of the common stock on the date that notice to repurchase is provided to the Company.  The total number of shares to be 
repurchased will be sufficient to provide proceeds which are the lesser of $2,500,000 or the amount of estate taxes and administrative 
expenses incurred by the Chairman’s estate.

The Company may elect to pay the purchase price in cash or may elect to pay cash equal to 25% of the total amount due and to 
execute a promissory note for the balance, payable over four years, at the prime rate of interest.  The Company maintains a $1,150,000 
life insurance policy to fund a substantial portion of this obligation. 

In April 1995, the Board of Directors approved a stock repurchase program authorizing the Company to purchase from time to time up 
to $2,000,000 of its common stock for its own account.  Subsequently, the Board of Directors periodically has approved increases in 
the stock repurchase program.  As of June 30, 2010, the most recently approved increase was for additional purchases of $2,000,000, 
which occurred in October 2006, for an aggregate maximum of $45,500,000, of which $43,360,247 had been expended through 
June 30, 2010.  The Company repurchased 7,996 shares for $43,620 in 2009.  No shares were repurchased in 2010. 

8.             INCOME TAXES 

The Company utilizes the liability method of accounting for income taxes.  The liability method measures the expected income tax 
impact of future taxable income and deductions implicit in the consolidated balance sheets.  The income tax benefit in 2010 and 2009 
consists of the following:

Deferred income tax balances reflect the effects of temporary differences between the tax bases of assets and liabilities and their 
carrying amounts.  These differences are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered.  
The recognition of these deferred tax balances will be realized through normal recurring operations and, as such, the Company has 
recorded the full value of such expected benefits. 

Accounting Standards Codification (“ASC”) Topic 740 prescribes a recognition threshold and measurement attribute for the financial 
statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return.  There were no significant 
matters determined to be unrecognized tax benefits taken or expected to be taken in a tax return that have been recorded on the 
Company’s consolidated financial statements for the year ended June 30, 2010.  As part of the unauthorized transactions, the 
Company has accrued interest of $660,989 and $354,644 at June 30, 2010 and 2009, respectively. 

Additionally, ASC Topic 740 provides guidance on the recognition of interest and penalties related to income taxes.  There were no 
penalties related to income taxes that have been accrued or recognized as of and for the years ended June 30, 2010 and 2009.  The 
Company records interest related to unrecognized tax benefits in interest expense. 

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

Unrecognized tax benefits at beginning of year
Gross decreases — tax positions in prior years
Unrecognized tax benefits at end of year

The Company files income tax returns in the United States federal jurisdiction and in a state jurisdiction.  The Company’s federal tax 
returns through tax year June 30, 2006 are settled and the income tax returns for tax years beginning July 1, 2006 are open.  Most state 
jurisdictions have tax returns open for tax years beginning July 1, 2005.  There is an open examination by the Wisconsin Department 
of Revenue for the period July 1, 2005 through June 30, 2009.

12.          EMPLOYEE BENEFIT PLANS 

Substantially all domestic employees are participants in the Koss Employee Stock Ownership Trust under which an annual 
contribution in either cash or common stock may be made at the discretion of the Board of Directors.  The expense recorded for such 
cash contributions approximated $5,000 and $30,000 during 2010 and 2009, respectively. 

The Company maintains a retirement savings plan under Section 401(k) of the Internal Revenue Code.  This plan covers all employees 
of the Company who have completed one full fiscal quarter of service.  Matching contributions can be made at the discretion of the 
Board of Directors.  For fiscal years 2010 and 2009, the matching contribution was 100% of employee contributions to the plan.  
Vesting of Company contributions occurs immediately.  Company contributions were $323,540 and $312,822 during 2010 and 2009, 
respectively. 

13.          DEFERRED COMPENSATION 

The Company has deferred compensation agreements with a former and current officer. 

The Board of Directors entered into an agreement to continue the Chairman’s 1991 base salary for the remainder of his life.  These 
payments begin upon the Chairman’s retirement, and since the Chairman has not retired, he is not currently receiving any payments 
under this arrangement.  The Company has a deferred compensation liability of $494,755 and $421,469 recorded as of June 30, 2010 
and 2009, respectively.  Deferred compensation expense of $73,286 and $66,808 was recognized under this arrangement in 2010 and 
2009, respectively. 

The Board of Directors has approved a supplemental retirement plan with an officer that calls for annual cash compensation following 
retirement from the Company in an amount equal to 2% of base salary, as defined in the agreement, multiplied by the number of years 
of service to the Company.  The retirement payments are to be paid monthly to the officer until his death and then to his surviving 
spouse monthly until her death.  The Company has a deferred compensation liability of $1,257,704 and $1,119,771 recorded as of 
June 30, 2010 and 2009, respectively.  Deferred compensation expense of $137,933 and $147,734 was recognized under this 
arrangement in 2010 and 2009, respectively. 

The Company uses life insurance policies to cover its deferred compensation agreements. 

14.          FOREIGN SALES AND SIGNIFICANT CUSTOMERS 

The Company’s net foreign sales amounted to $20,416,375 during 2010 and $17,495,075 during 2009.

15.          COMMITMENTS AND CONTINGENCIES 

The Company leases its facility in Milwaukee, Wisconsin from its Chairman.  On August 15, 2007, the lease was renewed for a period 
of five years, ending June 30, 2013, and is being accounted for as an operating lease.  The lease extension maintained the rent at a 
fixed rate of $380,000 per year.  The Company is responsible for all property maintenance, insurance, taxes and other normal expenses 
related to ownership.  Total rent expense was $380,000 in both 2010 and 2009. 

In July 2010, the Company entered into agreements totaling approximately $1,578,000 for software and new product development.  
The term of these commitments is less than one year. 

16.          LEGAL MATTERS 

Since learning of the unauthorized transactions in December 2009, the Company has been named in the matters described below.  The 
Company has also initiated certain actions against third parties, which are also described below, and may bring additional claims 
against other third parties. 

•      On January 11, 2010, the Company received a letter from a law firm stating that it represented a shareholder and 

demanding that the Company’s Board of Directors investigate and take legal action against all responsible parties to 
ensure compensation for the Company’s losses stemming from the unauthorized transactions.  The Company’s legal 
counsel has responded preliminarily to the letter indicating that the Board of Directors will determine the appropriate 
course of action after the Independent Investigation is completed. 

•      On January 15, 2010, a class action complaint was filed in federal court in Wisconsin against the Company, Michael 

Koss and Sujata Sachdeva.  The suit alleges violations of Section 10(b), Rule 10b-5 and Section 20(a) of the Exchange 
Act relating to the unauthorized transactions and requests an award of compensatory damages in an amount to be proven 
at trial.  See David A. Puskala v. Koss Corporation, et al., United States District Court, Eastern District of Wisconsin, 
Case No. 2:2010cv00041. 

•      On January 26, 2010, the SEC’s Division of Enforcement advised the Company that it obtained a formal order of 

investigation in connection with the unauthorized transactions. The Company voluntarily brought the unauthorized 
transactions to the SEC staff’s attention when they were discovered in December 2009, and is cooperating with the 
ongoing SEC investigation. 

•       On February 16 and 18, 2010, separate shareholder derivative suits were filed in Milwaukee County Circuit Court in 
connection with the previously disclosed unauthorized transactions. The first suit names as defendants Michael Koss, 
John Koss Sr., the other Koss directors, Sujata Sachdeva, Grant Thornton, LLP, and Koss Corporation (as a nominal 
defendant); the second suit names the same parties except Grant Thornton, LLP. Among other things, both suits allege 
various breaches of fiduciary and other duties, and seek recovery of unspecified damages and other relief. See Ruiz v. 
Koss, et al., Circuit Court, Milwaukee County, Wisconsin, No. 10CV002422 (February 16, 2010) and Mentkowski v. 
Koss, et al., Circuit Court, Milwaukee County, Wisconsin, No. 10CV002290 (February 18, 2010).  These two 
shareholder derivative suits have been consolidated under Master File No. 10CV002422. 

•       On February 18, 2010, the Company filed an action against American Express Company, American Express Travel 

Related Services Company, Inc., AMEX Card Services Company, Decision Science, and Pamela S. Hopkins in Superior 
Court of Maricopa County, Arizona, case no. CV2010-006631, alleging various claims of aiding and abetting breach of 
fiduciary duty, aiding and abetting fraud, conversion, and negligence relating to the unauthorized transactions.

Table of Contents 

•       On June 24, 2010, the Company filed an action against its former independent auditor, Grant Thornton, LLP, and Ms. 
Sachdeva, in Circuit Court of Cook County, Illinois, alleging various claims of accounting malpractice, negligent 
misrepresentation, and fraud relating to the unauthorized transactions. 

The ultimate resolution of these matters is not determinable.

CODE OF ETHICS 

Exhibit 14

The Board of Directors (the “Board”) of Koss Corporation, a Delaware corporation (the “Company”), have adopted this Code of 
Ethics for the Company’s directors, officers and employees (the “Code”). 

I.              PURPOSE 

This Code is intended to focus the Board, management and our employees on areas of ethical risk, provide guidance to help 
them recognize and deal with ethical issues, provide mechanisms to report unethical or unlawful conduct, and to help 
enhance and formalize our culture of integrity, honesty and accountability.  This Code is also designed to establish the 
policies and appropriate standards concerning business conduct, responsibilities and conflicts of interest.  This Code applies 
to the directors and employees of the Company. 

II.            WAIVERS 

Any waiver of Parts III A and B of this Code with respect to a director, an executive officer, and each financial or accounting 
officer at the level of the principal accounting officer or controller or above, may be made only by the Board and shall be 
promptly disclosed as required in accordance with the rules and regulations promulgated by the SEC and Nasdaq.  Waivers 
with respect to other employees may be made only by the Board.  The Board shall carefully evaluate any requested waiver 
and shall ensure that all waivers of this Code will not harm the Company or its reputation.  No waivers of the requirements of 
Parts III. C through G of this Code may be granted. 

III.           POLICIES 

A.            Conflicts of Interest 

The Company requires disclosure of related-party transactions and conflicts of interest, and seeks to avoid such 
transactions as well as the appearance of conflicts, where practicable.  A conflict of interest occurs when the private 
investments, business affairs or financial interests of an individual employee or the employee’s immediate family 
interfere with the interests, assets, or business of the Company as a whole. Potential conflicts must be fully and 
promptly disclosed to the Company’s designated Compliance Officer, his/her designee or a member of the Board. 

B.            Corporate Opportunities 

This Code prohibits (i) taking personally, participating or investing in on a personal basis, or diverting to others any 
business or investment opportunities that the employee learns about through the use of corporate property, 
information or position or that are discovered or disclosed in the course of the Company’s business, (ii) using 
Company property, information or position for personal gain, and (iii) competing with the Company.  Directors and 
employees owe a duty to the Company to advance its legitimate interests when the opportunity to do so arises. 

C.            Confidentiality 

Directors and employees of the Company should maintain the confidentiality of information entrusted to them by 
the Company or its customers, except when disclosure is authorized or legally mandated.  Confidential information 
includes all non-public information that might be of use to competitors, or harmful to the Company or its customers, 
if disclosed. 

1 

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
 
D.            Fair Dealing 

Each director and employee of the Company should endeavor to deal fairly with the Company’s customers, 
suppliers, competitors and employees.  None should attempt to take unfair advantage of anyone through 
manipulation, concealment, abuse of privileged information, misrepresentation of material facts or any other unfair-
dealing practice. 

E.            Protection and Proper Use of Company Assets 

Directors and employees should protect the Company’s assets and seek to ensure the proper use of the Company’s 
and its customers’ property, electronic communication systems, information resources, materials, facilities, and 
equipment.  All assets should be used and maintained with reasonable care and respect, guarding against waste and 
abuse, and Company assets or property should never be borrowed or removed without express permission from the 
department head responsible for that asset.  In the case of executive officers and directors, any loan or removal of 
Company property or assets requires approval by the Chairman of the Board of Directors and disclosure to the 
Board. Directors and employees should be cost-conscious and alert to opportunities to improve performance while 
reducing costs.  All Company assets should be used only for legitimate business purposes. 

F.            Compliance with Laws, Rules and Regulations 

Directors and employees of the Company will conduct the business of the Company in accordance with all 
applicable laws, rules and regulations, and shall comply with applicable policies and procedures of the Company, 
including this Code. 

G.            Reporting of Illegal or Unethical Behavior 

Directors and employees of the Company must report any knowledge or reasonable suspicion of violations of any 
laws, rules or regulations or any violations of this Code.  Such report must comply with the reporting procedures 
described in Section IV(A) of this Code. 

H.            Disclosure. 

The information in the Company’s public communications, including SEC filings, must be full, fair, accurate, timely 
and understandable.  All directors and employees of the Company are responsible for acting in furtherance of this 
policy.  In particular, directors and executive officers are required to maintain familiarity with the disclosure 
requirements applicable to the Company commensurate with their duties and are prohibited from knowingly 
misrepresenting, omitting or causing others to misrepresent or omit, material facts about the Company to others, 
whether within or outside the Company, including the Company’s independent auditors.  In addition, any director or 
employee who has a supervisory role in the Company’s disclosure process has an obligation to discharge such 
supervisory responsibilities in good faith and in the Company’s best interests. 

IV.           COMPLIANCE STANDARDS AND PROCEDURES 

This Code is designed to provide a method to report conduct that directors and employees suspect violates this Code.  The 
Company encourages participation by all employees in this effort. 

If actions have taken place, may be taking place, or may be about to take place that violate any law, rule or regulation or any 
provision of this Code, it should be brought to the attention of appropriate authorities within the Company. 

A.            Procedure to Report Violations or Suspected Violations 

1.             Failure to report a known violation of these policies may result in disciplinary action up to and including 

dismissal.  If an employee has knowledge of or reasonably suspects misconduct or a violation of this Code, 
the matter should first be brought to the attention  

2 

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
 
of his/her immediate supervisor or, in the case of a director with knowledge, to the attention of the Chief 
Executive Officer or the Board. 

2.             If the conduct in question involves a reporting individual’s supervisor, the reporting individual believes that 
a supervisor has not dealt with the matter properly, or feels they cannot discuss the matter with a 
supervisor, the reporting individual may raise the matter with the next level of management or report it to 
the Board.  If a reporting individual is uncomfortable reporting to any of the above persons, or feels that the 
report has not been dealt with properly, the individual may report it directly to the Compliance Officer or a 
representative of the Board. 

3.             In reviewing a report, a manager should consider whether the report alleges or implicates a violation of this 

Code and if so, he or she must report it immediately to the next level of management and the Company’s 
designated Compliance Officer, or where appropriate, to a representative of the Board. 

4.             When reporting misconduct or suspected misconduct, the Company prefers that the reporting individual 

discloses his/her identity in order to facilitate the Company’s ability to take appropriate steps to address the 
report, including conducting an investigation.  If anyone wishes to remain anonymous, he/she may do so; 
however, they should be aware that if they do not identify themselves, the Company may not have 
sufficient information to properly investigate their allegations.  When a report relates to an accounting or 
auditing issue, the complaint procedures adopted by the Audit Committee of the Board supersede these 
provisions, but only to the extent these provisions are inconsistent. 

5.             Any employee involved in any capacity in an investigation of a possible violation of any law, rule or 
regulation, or any provision of this Code, should maintain the confidentiality of the investigation and 
should not discuss the subject matter of the investigation with anyone other than those participating in the 
investigation, unless required by law or when seeking their own legal advice, if necessary. 

B.            Consequences of Failure to Comply 

1.             If a director or employee violates this Code, fails to properly report a violation of this Code or intentionally 

submits a false report, he/she will be subject to discipline. In the event of a violation of any law, rule or 
regulation, the violation may be reported to the appropriate law enforcement authorities. The discipline 
imposed will vary depending on the nature, severity, and frequency of the violation as well as the status of 
the person involved.  Discipline will be imposed for violations of this Code, failure to report violations and 
withholding relevant and material information concerning violations. Directors and employees will be 
informed of the charges against them and will be given the opportunity to explain their actions before any 
disciplinary action is imposed. 

2.             Varying levels of disciplinary action may be imposed, including: 

(a)           Verbal Warning 
(b)           Written Warning 
(c)           Written Reprimand 
(d)           Probation 
(e)           Suspension 
(f)            Termination or Removal 

3 

  
  
  
  
  
  
  
  
  
  
 
3.             Offenders may also be subject to criminal prosecution and civil liability, including compensating the 

Company or other injured parties for their loss. 

4.             No employee may be retaliated against for reporting in good faith to the Company, in accordance with this 
Code, any suspected misconduct or violation of this Code.  Any employee who believes he or she has been 
retaliated against, or threatened with retaliation, should inform the Director of Human Resources, the 
Compliance Officer or a representative of the Board immediately.  Employees or directors who violate this 
non-retaliation policy will be subject to discipline.  Individuals are expected to act responsibly and ethically 
in reporting under this Code.  Employees and directors must not use this Code or any of its procedures in 
bad faith or in a false or frivolous manner.
