CHAIRMAN’S STATEMENT   

TO OUR SHAREHOLDERS 

2015 represented a year of stabilization for  O2Micro as we have realigned the Company to return to growth and 
profitability.  Through  a  combination  of  operational  expense  reductions  and  the  implementation  of  certain 
initiatives to monetize assets of the Company, we believe we have transitioned the Company to benefit from our 
next  growth  phase.  Our  high-priority  initiatives  to  deliver  superior  customer  solutions  resulted  in  design-win 
momentum  in  our  new  tablet  and  smartphone  products  and  the  expansion  of  our  customer  base  in  our 
backlighting, battery management, power management and general lighting markets.   

We  view  2016  as  a  potential  growth  year  for  the  Company  in  terms  of  year-over-year  revenue  growth  as  we 
believe  we  are  well  aligned with  the mega-trends  in  the  industry-including 4K TV, battery  management  and  LED 
general  lighting.  We  believe  in  this  development  for  a  number  of  significant  reasons  including:  Due  to  ongoing 
customer product ramps, we sustained higher quarterly revenues in each quarter of Fiscal year 2015.    Second, we 
do not believe that we will face additional declines in our power management business for notebook computers, 
as  we  believe  this  business has  stabilized. Next,  we  believe  our  higher  growth  drivers  including  products  for  the 
tablet  and  smartphone  markets,  general  lighting  and  battery  management  products  will  represent  an  increasing 
portion  of  total  revenue  as  we  proceed  throughout  2016  and  into  2017.  Finally,  we  have  reduced  operational 
expenses by approximately fifty percent from fiscal year-end 2012 levels and we believe that we have achieved the 
necessary expense structure to return to profitability in the near future. 

In 2015, we dedicated approximately 65% of our R&D spending to developing new innovative products. As a result, 
customer design activity with our new products has been robust, and should continue into 2016. In fact, revenue 
from new products accounted for approximately 32% of total revenue in 2015. As this trend continues, new design 
revenue will continue to gain momentum in diverse markets and expand our customer base for our LED general 
lighting, backlighting, battery management and power management products. 

O2Micro’s  proprietary,  analog  power  management  technology  in  our  battery  management  segment  supports  a 
variety  of  end  markets  and  this  business  enjoyed  excellent  year-over-year  growth  in  2015.  Our  battery 
management  products  not  only  exceeded  our  stated  goal  of  reaching  fifteen  percent  of  second  half    2015 
revenue, but we are now expecting sales from these products to represent approximately twenty to twenty five 
percent of our projected 2016 revenues. This will make battery management the second largest product line for 
O2Micro in 2016. Our battery management products continue to achieve many new design wins, and we continue 
to be very optimistic for continued growth in power tool, e-bike, e-vehicle, appliances and vacuum cleaner markets. 
We  are  also  seeing  increasing  design  activity  for  products  in  uninterrupted  power  supply  applications.  Major 
manufacturers using our products include Black & Decker, Electrolux, LG, Panasonic, and TTI, to name a few. 

In our backlighting business, we are projecting renewed growth in this product area as we move into 2016, based 
on increasing design activity in TV and Monitor and the emergence and increasing penetration rate of 4K TVs. We 
continue to be a worldwide leader in LED backlighting for TVs and monitors, and our expanding customer base in 
our backlighting business includes such market leaders as Sony, Toshiba, HP, Dell, Lenovo, Skyworth, TCL, Hisense, 
among others.   

The Company continues to garner design wins for the smartphone and tablet markets. I am pleased to report that 
our efforts are paying off and we achieved multiple significant design wins with several platform providers who are 
integrating O2Micro products into high-volume tablet and smartphone products.     

Our LED general lighting business continues to grow in this competitive market as we remain focused on the higher 
end of this market. We are very pleased that an increasing number of market leaders are using our general lighting 
product technologies. This customer list includes GE, Panasonic, Samsung, Toshiba, Osram, IKEA, Philips, Lights of 
America, and TCP, and we continue to see a broader-based acceptance of our proprietary Free Dimming and two- 
color dimming products in more applications, thereby expanding our international customer base.     
In 2016, O2Micro is well positioned with a more cost-efficient business model, strong secular growth drivers and 
proven  strategies  in  place  to  return  to  profitability  in  the  near  future.  Our  Management  Team  is  diversified  and

experienced. We are also in the process of monetizing some of our real-estate assets and long-term investments. 
Returns  to  shareholders  are  a  top  priority  and we  continue  to  be  active  in  our  share repurchase  program.  Since 
2002,  we  have  repurchased  approximately  nineteen  million  ADS  shares  for  approximately  one  hundred  million 
dollars. We strongly believe we have one of the strongest international infrastructure support organizations in the 
industry, which will enable us to foster future growth and sustainability in the years to come. 

We thank you for your support and we look forward to reporting our progress to you throughout the year.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and the Shareholders of O2Micro International Limited:   

We have audited the accompanying consolidated balance sheets of O2Micro International Limited and subsidiaries 
(the  “Company”)  as  of  December  31,  2015  and  2014,  and  the  related  consolidated  statements  of  operations  and 
comprehensive  income,  shareholders’  equity,  and  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31, 2015 (expressed in United States dollars).    These 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 financial statements are free of material misstatement.    An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.    An audit also includes assessing the 
accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
financial statement presentation.    We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of 
O2Micro  International  Limited  and  subsidiaries  as  of  December  31,  2015  and  2014,  and  the  results  of  their 
operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity 
with accounting principles generally accepted in the United States of America.     

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States),  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2015,  based  on  the  criteria 
established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations 
of  the  Treadway  Commission,  and  our  report  dated  April  28,  2016  expressed  an  unqualified  opinion  on  the 
Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM   

To the Board of Directors and the Shareholders of O2Micro International Limited: 

We have audited the internal control over financial reporting of O2Micro International Limited and subsidiaries (the 
“Company”)  as  of  December  31,  2015,  based  on  criteria  established  in  Internal  Control  -  Integrated  Framework 
(1992)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.    The  Company’s 
management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual 
Report on Internal Control over Financial Reporting.    Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit.   

We  conducted  our  audit  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  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.    Our  audit 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness  exists,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances.    We believe 
that our audit provides a reasonable basis for our opinion. 

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

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion 
or improper management override of controls, material misstatements due to error or fraud may not be prevented 
or detected on a timely basis.    Also, projections of any evaluation of the effectiveness of the internal control over 
financial  reporting  to  future  periods  are  subject  to  the  risk  that  the  controls  may  become  inadequate  because  of 
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.   

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2015, based on the criteria established in Internal Control - Integrated Framework (1992) issued 
by the Committee of Sponsoring Organizations of the Treadway Commission.   

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated financial statements as of and for the year ended December 31, 2015, of the Company and 
our report dated April 28, 2016 expressed an unqualified opinion on those financial statements.

The  Company’s  ordinary  shares  (“Shares”)  were  initially  listed  on  The  NASDAQ  National  Market 
(“NASDAQ”) on August 23, 2000, and on the Cayman Islands Stock Exchange on February 1, 2001.    At the 
Extraordinary  General  Meeting  of  Shareholders  (“EGM”)  held  on  November  14,  2005,  the  shareholders 
approved  a  public  global  offering  of  the  Company’s  Shares  and  the  proposed  listing  of  the  Company's 
Shares  on  the  Main  Board  of  The  Stock  Exchange  of  Hong  Kong  Limited  (“SEHK”)  and  various  matters 
related  to  the  proposed  listing  and  offering.    Following  the  approval  of  these  matters,  the  Company 
ceased trading its Shares on  the NASDAQ, effected a 50-for-1 share split of Shares, created an American 
depositary share (“ADS”) program for the ADSs to be quoted on the NASDAQ, and delisted the Shares from 
the  NASDAQ  on  November  25,  2005.    The  Company  commenced  trading  of  ADSs  on  the  NASDAQ  on 
November  28,  2005,  and  subsequently  listed  the  Shares  on  the  SEHK  on  March  2,  2006,  by  way  of 
introduction.    On February 27, 2009, the Company submitted an application for the voluntary withdrawal 
of the listing of Shares on the Main Board of SEHK (collectively referred to as “Proposed Withdrawal”) for 
reasons  of  cost  and  utility.    The  Company  retained  its  existing  primary  listing  of  ADSs  on  the  NASDAQ 
following  the  Proposed  Withdrawal  and  for  the  foreseeable  future.    The  Proposed  Withdrawal  was 
approved  at  the  EGM  held  on  May  30,  2009,  and  the  listing  of  the  Shares  on  SEHK  was  withdrawn  on 
September 9, 2009.   

The  Company  has  incorporated  various  wholly-owned  subsidiaries  in  the  past,  including,  among  others, 
O2Micro Electronics, Inc. (“O2Micro-Taiwan”), O2Micro International Japan Ltd. (“O2Micro-Japan”), O2Micro 
(China) Co., Ltd. (“O2Micro-China”), and O2Security Limited (“O2Security”).    O2Micro-Taiwan is engaged in 
operations and sales support services. O2Micro-Japan is engaged in sales support services. O2Micro-China 
and  other  subsidiaries  are  mostly  engaged  in  research  and  development  services.    O2Security  was 
primarily engaged in operations and sales of Network Security products (“Network Security Group”).    In 
November 2010, the Company commenced a plan to terminate its Network Security business and initiated 
shutdown  activities  associated  with  the  Network  Security  Group,  and  in  2011,  the  Company  formally 
dissolved  all  business  entities  related  to  O2Security  Limited.    The  Company  has  reflected  the  operating 
results of this business group as discontinued operations in the accompanying consolidated statements of 
operations and comprehensive income.    Please also see discussions in note 3.   

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Basis of Presentation 

The  consolidated  financial  statements  have  been  prepared  in  accordance  with  accounting  principles 
generally  accepted  in  the  United  States  of  America.    The  consolidated  financial  statements  include  the 
accounts of the Company and its wholly-owned subsidiaries.    All intercompany accounts and transactions 
have been eliminated on consolidation.

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  certain 
reported amounts and disclosures.    Accordingly, actual results could differ from those estimates.   

Significant  accounting  estimates  reflected  in  the  Company’s  consolidated  financial  statements  include 
valuation  allowance 
for  doubtful  accounts, 
other-than-temporary  impairment  of  securities,  inventory  valuation,  useful  lives  for  property  and 
equipment, impairment of long-lived assets and identified intangible assets, allowances for sales returns, 
pension and uncertain tax liabilities, contingencies and stock-based compensation.

for  deferred 

income 

Concentration of Credit Risk 

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, 
cash  equivalents,  short-term  investments  and  accounts  receivable.    Cash  is  deposited  with  high  credit 
quality  financial  institutions.    For  cash  equivalents  and  short-term  investments,  the  Company  invests 
primarily  in  time  deposits  at  the  banks  with  good  credit  rating.    For  accounts  receivable,  the  Company 
performs ongoing  credit evaluations of its customers’ financial condition and the Company maintains an 
allowance for doubtful accounts based upon a review of the expected collectability of individual accounts. 

Fair Value of Financial Instruments 

The  Company’s  financial  instruments  include  cash  and  cash  equivalents,  restricted  cash,  accounts 
receivable, and notes and accounts payable. The carrying amounts approximate the fair value due to the 
short-term  maturity  of  those  instruments.    Fair  value  of  available-for-sale  investments  including 
short-term  investments  and  long-term  investments  is  based  on  quoted  market  prices.    Long-term 
investments  in  private  company  equity  securities  are  accounted  for  under  the  cost  method  because  the 
Company  does  not  exercise  significant  influence  over  the  entities.    The  Company  evaluates  related 
information  including  operating  performance,  subsequent  rounds  of  financing,  advanced  product 
development and related business plan in determining the fair value of these investments and whether an 
other-than-temporary decline in value exists.     

Cash and Cash Equivalents   

The Company considers all highly liquid investments with maturities of not more than three months when 
purchased to be cash equivalents.    Investments with maturities of more than three months are classified 
as short-term investments.   

Restricted Cash 

The Company classifies deposits made for customs and cash pledged to a bank for the issuance of letters 
of  credit  as  restricted  cash.    The  deposits  are  classified  as  current  assets  if  refundable  within  a 
twelve-month period from the balance sheet date.   

Short-term Investments 

The Company maintains its excess  cash in time deposits,  government,  corporate, or other agency bonds 
issued  with  high  credit  ratings.    The  specific  identification  method  is  used  to  determine  the  cost  of 
securities  sold,  with  realized  gains  and  losses  reflected  in  non-operating  income  and  expenses.    All  the 
above-mentioned investments except for time deposits were classified as available-for-sale securities and 
were recorded at fair value. Unrealized gains and losses on these investments are included in accumulated 
other comprehensive income and loss as a separate component of shareholders’ equity, net of any related 
tax effect, unless unrealized losses are deemed other-than-temporary.    Unrealized losses are recorded as 
a charge to income when deemed other-than-temporary.    There were no available-for-sale securities as 
of December 31, 2015 and 2014. 

Investment transactions are recorded on the trade date.

Inventories 

Inventories are stated at the lower of standard cost or market value.    The cost of inventories comprises 
cost  of  purchasing  raw  materials  and  where  applicable,  those  overheads  that  have  been  incurred  in 
bringing  the  inventories  to  their  present  location  and  condition.    Cost  is  determined  on  a  currently 
adjusted  standard  basis,  which  approximates  actual  cost  on  a  first-in,  first-out  basis.    The  Company 
assesses its inventory for estimated obsolescence or unmarketable inventory based upon management’s 
assumptions about future demand and market conditions and writes down inventory as needed.   

Long-term Investments 

Long-term  investments  in  private  companies  over  which  the  Company  does  not  exercise  significant 
influence  are  accounted  for  under  the  cost  method.  Management  evaluates  related  information  in 
determining  whether  an  other-than-temporary  decline  in  value  exists.    Factors  indicative  of  an 
other-than-temporary decline include recurring operating losses, credit defaults and subsequent rounds of 
financing  at  an  amount  below  the  cost  basis  of  the  investment.  The  list  is  not  all-inclusive  and 
management periodically weighs all quantitative and qualitative factors in determining if any impairment 
loss exists.   

Long-term investments in listed companies are classified as available-for-sale securities and are recorded 
at  fair  value.    Unrealized  gains  and  losses  on  these  investments  are  included  in  accumulated  other 
comprehensive income and loss as a separate component of shareholders’ equity, net of any related tax 
effect,  unless  unrealized  losses  are  deemed  other-than-temporary.    Unrealized  losses  are  recorded  as  a 
charge to income when deemed other-than-temporary. 

Property and Equipment 

Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Major  additions  and 
betterments are capitalized, while maintenance and repairs are expensed as incurred. 

Depreciation  is  computed  on  a  straight-line  basis  over  estimated  service  lives  that  range  as  follows: 
buildings  -  35  to  50  years,  equipment  -  3  to  10  years,  furniture  and  fixtures  -  3  to  9  years,  leasehold 
improvements  -  the  shorter  of  the  estimated  useful  life  or  the  lease  term,  which  is  2  to  6  years,  and 
transportation equipment - 5 years.   

Assets held for sale 

The Company considers assets to be held for sale (a) when management or others having the authority to 
do  so  approve  a  plan  to  sell  the  assets,  (b)  the  assets  are  available  for  immediate  sale  in  their  present 
condition, (c) the Company has initiated an active program to locate a buyer and other actions required to 
complete the plan to sell the assets, (d) consummation of the transactions is probable and is expected to 
qualify for recognition as a completed sale, within one year, (e) the assets are being actively marketed for 
sale at a price that is reasonable in relation to their current fair value, and (f) the significant changes to the 
plan to sell the assets are not expected to be made or the plan is not expected to be withdrawn. When 
property and equipment are classified as held for sale, the Company discontinues depreciating the assets 
and measures the assets at lower of their carrying amount and fair value less costs to sell. 

Long-lived Asset Impairment 

The  Company  evaluates  the  recoverability  of 
in 
circumstances  indicate  the  carrying  value  may  not  be  recoverable.    The  carrying  value  of  a  long-lived 
asset  is  considered  impaired  when  the  anticipated  undiscounted  cash  flows  from  the  asset  is  separately 
identifiable and is less than the carrying value.    If impairment occurs, a loss based on the excess of the 
carrying  value  over  the  fair  value  of  the  long-lived  asset  is  recognized.    Fair  value  is  determined  by 
reference to quoted market prices, if available, or discounted cash flows, as appropriate. 

long-lived  assets  whenever  events  or  changes 

Treasury Stock 

The Company may retire ordinary shares repurchased under a share repurchase plan.    Accordingly, upon 

- 15 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
retirement the excess of the purchase price over par value is allocated between additional paid-in capital 
and retained earnings based on the average issuance price of the shares repurchased.    The Company may 
also determine not to retire ordinary shares repurchased for the purpose of reissuing them upon exercise 
of stock option, Employee Stock Purchase Plan, and release of restricted stock units (“RSUs”).    The reissue 
cost  of  shares  repurchased  is  determined  by  the  moving  average  method.    A  repurchase  of  ADS  is 
recorded as treasury stock until the Company completes the withdrawal of the underlying ordinary shares 
from the ADS program.   

Revenue Recognition 

Revenue from product sales to customers, other than distributors, is recognized at the time of shipment 
and when title and right of ownership transfers to customers.    The four criteria for revenue being realized 
and earned are the existence of evidence of sale, actual shipment, fixed or determinable selling price, and 
reasonable assurance of collectability. 

Allowances  for  sales  returns  and  discounts  are  provided  at  the  time  of  the  recognition  of  the  related 
revenues on the basis of experience and these provisions are deducted from sales. 

In  certain  limited  instances,  the  Company  sells  its  products  through  distributors.    The  Company  has 
limited  control  over  these  distributors’  selling  of  products  to  third  parties.    Accordingly,  the  Company 
recognizes  revenue  on  sales  to  distributors  when  the  distributors  sell  the  Company’s  products  to  third 
parties.    Thus, products held by distributors are included in the Company’s inventory balance. 

Freight Costs 

Costs of shipping and handling for delivery of the Company’s products that are reimbursed by customers 
are  recorded  as  revenue  in  the  consolidated  statements  of  operations  and  comprehensive  income.   
Shipping and handling costs are charged to cost of sales as incurred. 

Research and Development 

Research and development costs consist of expenditures incurred during the course of planned research 
and investigation aimed at the discovery of new knowledge and intellectual property that will be useful in 
developing  new  products  or  processes,  or  at  significantly  enhancing  existing  products  or  production 
processes  as  well  as  expenditures  incurred  for  the  design  and  testing  of  product  alternatives  or 
construction  of  prototypes.    All  expenditures  related  to  research  and  development  activities  of  the 
Company are charged to operating expenses when incurred. 

Advertising Expenses   

The  Company  expenses  all  advertising  and  promotional  costs  as 
  These  costs  were 
approximately $782,000, $948,000, and $1,349,000 in 2015, 2014, and 2013, respectively.    A portion of 
these costs  was for advertising, which approximately amounted to $236,000, $205,000, and $297,000 in 
2015, 2014, and 2013, respectively. 

incurred. 

Pension Costs   

For employees under defined contribution pension plans, pension costs are recorded based on the actual 
contributions made to employees’ pension accounts.    For employees under defined benefit pension plans, 
pension costs are recorded based on the actuarial calculation. 

Government Grants 

Government  grants received  by the Company to assist  with specific research and development activities 
are  recognized  as  non-operating  income.  If  the  Company  has  an  obligation  to  repay  any  of  the  funds 
provided by government grants regardless of the outcome of the research and development, the Company 
will estimate that obligation and recognize the amount as a liability.

Income Tax 

The provision for income tax represents income tax paid and payable for the current year plus the changes 
in  the  deferred  income  tax  assets  and  liabilities  during  the  relevant  years.    Deferred  income  tax  assets 
and  liabilities  are  recognized  for  the  future  tax  consequences  attributable  to  differences  between  the 
financial  statement  carrying  amount  of  existing  assets  and  liabilities  and  their  respective  tax  bases,  and 
operating loss and tax credit carryforwards.    The Company believes that uncertainty exists regarding the 
realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance 
for those deferred income tax assets to the extent the realizability is not deemed to be more likely than 
not.    Deferred income tax assets and liabilities are measured using enacted tax rates.   

The Company utilizes a two-step approach to recognizing and measuring uncertain tax positions. The first 
step  is  to  evaluate  the  tax  position  for  recognition  by  determining  if  the  weight  of  available  evidence 
indicates it is more likely than not that the position will be sustained in a dispute with taxing authorities, 
including resolution of related appeals or litigation processes, if any.    The second step is to measure the 
tax  benefit  as  the  largest  amount  which  is  more  than  50%  likely  of  being  realized  upon  ultimate 
settlement.     

Stock-based Compensation 

The  Company  grants  stock  options  to  its  employees  and  certain  non-employees  and  estimates  the  fair 
value of share-based payment awards on the date of grant using an option-pricing model.    The value of 
the  portion  of  the  award  that  is  ultimately  expected  to  vest  is  recognized  as  expense  ratably  over  the 
requisite  service  periods.    The  Company  has  elected  to  use  the  Black-Scholes  option  pricing  model  to 
determine  the  fair  value  of  stock  options  on  the  date  of  grant.    The  Company  also  grants  RSUs  to  its 
employees and the RSUs are measured based on the fair market value of the underlying stock on the date 
of grant.       

Foreign Currency Transactions   

The functional currency is the local currency of the respective entities.    Foreign currency transactions are 
recorded at the rate of exchange in effect when the transaction occurs.    Gains or losses, resulting from 
the  application  of  different  foreign  exchange  rates  when  cash  in  foreign  currency  is  converted  into  the 
entities’ functional currency, or when foreign currency receivable and payable are settled, are credited or 
charged  to  income  in  the  period  of  conversion  or  settlement.    At  year-end,  the  balances  of  foreign 
currency monetary assets and liabilities are recorded based on prevailing exchange rates and any resulting 
gains or losses are credited or charged to income. 

Translation of Foreign Currency Financial Statements 

The  reporting  currency  of  the  Company  is  the  US  dollar.    Accordingly,  the  financial  statements  of  the 
foreign  subsidiaries  are  translated  into  US  dollars  at  the  following  exchange  rates:  assets  and  liabilities  - 
current rate on balance sheet date; shareholders’ equity - historical rate; income and expenses - weighted 
average rate during the year.    The resulting translation adjustment is recorded as a separate component 
of shareholders’ equity. 

Comprehensive Income (Loss) 

Comprehensive  income  (loss)  represents  net  income  (loss)  plus  the  results  of  certain  changes  in 
shareholders’ equity during a period from non-owner sources. 

Legal Contingencies 

The  Company  is  currently  involved  in  various  claims  and  legal  proceedings.    Periodically,  the  Company 
reviews  the  status  of  each  significant  matter  and  assesses  the  potential  financial  exposure.    If  the 
potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, 
the Company accrues a liability for the estimated loss.    In view of uncertainties related to these matters, 
accruals are based only on the best information available at the time.    As additional information becomes 
available, the Company reassesses the potential liability related to the pending claims and litigation and 

- 17 - 

 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
revises these  estimates as appropriate.    Such revisions in  the estimates of the potential liabilities  could 
have a material impact on the results of operations and financial position. 

As part of its standard terms and conditions, the Company offers limited indemnification to third parties 
with  whom  it  enters  into  contractual  relationships,  including  customers;  however,  it  is  not  possible  to 
determine the range of the amount of potential liability under these indemnification obligations due to the 
lack of prior indemnification claims.    These indemnifications typically hold third parties harmless against 
specified losses, such as those arising from a breach of representation or covenant, or  other third party 
claims  that  the  Company’s  products,  when  used  for  their  intended  purposes,  infringe  the  intellectual 
property  rights  of  such  other  third  parties.    These  indemnifications  are  triggered  by  any  claim  of 
infringement  of  intellectual  property  rights  brought  by  a  third  party  with  respect  to  the  Company’s 
products.    The terms of these indemnifications may not be waived or amended except by written notice 
signed by both parties, and may only be terminated with respect to the Company’s products. 

Recent Accounting Pronouncements     

In  April  2014,  the  Financial  Accounting  Standard  Board  (“FASB”)  issued  an  accounting  update,  which 
changes  the  criteria  for  reporting  discontinued  operations  for  all  public  and  nonpublic  entities.  The 
guidance requires only disposals that represent a strategic shift that has (or will have) a major effect on the 
entity’s  results  and  operations  would  qualify  as  discontinued  operations.  The  guidance  also  requires 
entities 1) to expand  their disclosures about discontinued operations to include more information about 
assets, liabilities, income, and expenses and 2) to disclose the pre-tax income attributable to a disposal of 
an  individually  significant  component  of  an  entity  that  does  not  qualify  for  discontinued  operations 
presentation  in  the  financial  statements.”  The  guidance  is  effective  for  fiscal  years  beginning  after 
December 15, 2014 and early adoption is prohibited. The adoption of this guidance did not have a material 
impact on the Company’s results of operations, financial position or cash flow. 

In  May  2014,  the  FASB  issued  a  new  standard  related  to  revenue  recognition.  Under  the  new  standard, 
recognition  of  revenue  occurs  when  a  customer  obtains  control  of  promised  goods  or  services  in  an 
amount  that  reflects  the  consideration  to  which  the  entity  expects  to  be  entitled  in  exchange  for  those 
goods  or  services.  In  addition,  the  new  standard  requires  disclosure  of  the  nature,  amount,  timing,  and 
uncertainty  of  revenue  and  cash  flows  arising  from  contracts  with  customers.  In  August  2015,  the  FASB 
issued an amendment to defer the effective date. The new standard is effective for fiscal years beginning 
after  December  15,  2017  and  early  adoption  is  permitted  for  annual  reporting  periods  beginning  after 
December  15,  2016.  In  March  and  April  2016,  the  FASB  issued  two  accounting  updates  to  clarify  the 
implementation  guidance  on  principal  versus  agent  considerations,  performance  obligations  and  the 
licensing.  The  new  guidance  is  required  to  be  applied  retrospectively  to  each  prior  reporting  period 
presented  or  retrospectively  with  the  cumulative  effect  of  initially  applying  it  recognized  at  the  date  of 
initial application. The Company is currently evaluating this guidance, but does not expect the adoption to 
have a material effect on the Company’s consolidated financial statements. 

In  June  2014,  the  FASB  issued  an  accounting  update,  which  clarifies  the  accounting  for  share-based 
payments. The guidance requires that a performance target that affects vesting and that could be achieved 
after the requisite service period is treated as a performance condition. The guidance is effective for fiscal 
years beginning after December 15, 2015 and early adoption is permitted. The adoption of this guidance is 
not expected to have a material impact on the Company’s results of operations, financial position or cash 
flow. 

In  August  2014,  the  FASB  issued  new  standard  related  to the  presentation  of  financial  statements  when 
there may be conditions or events that raise substantial doubt about the entity’s ability to continue as a 
going  concern.  This  standard  sets  forth  management’s  responsibility  to  evaluate,  each  reporting  period, 
whether there is substantial doubt about our ability to continue as a going concern, and if so, to provide 
related footnote disclosures. The standard is effective for fiscal years beginning after December 15, 2016 
and early adoption is permitted. The adoption of this guidance is not expected to have a material impact 
on the Company’s results of operations, financial position or cash flow. 

In  February  2015,  the  FASB  issued  an  accounting  update  to  amend  the  consolidation  analysis.  All  legal 
entities are subject to reevaluation under the revised consolidation model. The amendment is effective for 

- 18 - 

 
 
 
 
 
 
  
 
  
 
 
 
     
 
 
 
 
 
fiscal  years  beginning  after  December  15,  2015  and  early  adoption  is  permitted.  The  adoption  of  this 
amendment is not expected  to have a material impact on the Company’s results of operations,  financial 
position or cash flow.   

In  July  2015,  the  FASB  issued  an  accounting  update  to  simplify  the  measurement  of  inventory.  The 
amendment  requires  the  measurement  of  inventory  at  the  lower  of  cost  and  net  realizable  value.  Net 
realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable 
costs of completion, disposal, and transportation. The amendment applies to inventories for  which cost is 
determined by methods other than the last-in first-out and the retail inventory methods. This amendment is 
effective  prospectively  for  annual  periods  beginning  after  December  15,  2016  and  early  application  is 
permitted. The adoption of this amendment is not expected to have a material impact on the Company’s 
results of operations, financial position or cash flow. 

In November 2015, the FASB issued an accounting update to simplify the presentation of deferred income 
taxes.  The  amendment  requires  that  deferred  tax  liabilities  and  assets  be  classified  as  noncurrent  in  a 
classified statement of financial position. The current requirement that deferred tax liabilities and assets of 
a  tax-paying  component  of  an  entity  be  offset  and  presented  as  a  single  amount  is  not  affected  by  the 
amendments  in  this  guidance. This  amendment  is  effective  prospectively  or  retrospectively  for  annual 
periods  beginning  after  December  15,  2016  and  early  application  is  permitted.  The  Company  is  currently 
evaluating the effect this standard will have on its financial position. 

In January 2016, the FASB issued an accounting update regarding the subsequent measurement of equity 
investment. The amendment requires all equity investment to be measured at fair value with changes in 
the  fair  value  recognized  through  net  income  other  than  those  accounted  for  under  equity  method  of 
accounting  or  those  that  result  in  consolidation  of  the  investee.  The  amendment  also  simplifies  the 
impairment  assessment  of  equity  investments  without  readily  determinable  fair  value  by  requiring 
assessment  for  impairment  qualitatively  and  eliminating  the  complexity  of  the  other-than-temporary 
impairment guidance. For financial reporting, the amendment requires an entity to present separately in 
other comprehensive income the portion of the total change in the fair value of a liability resulting from a 
change  in  the  instrument-specific  credit  risk  when  the  entity  has  elected  to  measure  the  liability  at  fair 
value in accordance with the fair value option for financial instruments. In addition, for public company: 
the amendment eliminates the requirement to disclose the methods and significant assumptions used to 
estimate  the  fair  value  that  is  required  to  be  disclosed  for  financial  instruments  measured  at  amortized 
cost on the balance sheet; for nonpublic company: the amendment eliminates the requirement to disclose 
the fair value of financial instruments measured at amortized cost. This amendment is effective for fiscal 
years  beginning  after  December  15,  2017  and  early  application  is  prohibited.    The  adoption  of  this 
amendment  is  not  expected  to  have  a  material  impact  on  the  Company’s  financial  position,  results  of 
operations, cash flow and financial statement disclosures. 

In February 2016, the FASB issued a new standard regarding leases. The new standard requires an entity to 
recognize assets and liabilities arising from a lease for both financing and operating leases other than that 
the  entity  elects  the  short-term  lease  recognition  and  measurement  exemption.  Qualitative  and 
quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash 
flows arising from leases. This standard is effective for fiscal years beginning after December 15, 2018, and 
early adoption is permitted. The Company is currently evaluating the effect this standard will have on its 
financial position, results of operations, cash flow and financial statement disclosures. 

In  March  2016,  the  FASB  issued  an  accounting  update  to  simplify  several  aspects  of  the  accounting  for 
share-based payment award transactions, including the income tax consequences, classification of awards 
as either equity or liabilities, and classification on the statement of cash flows. The amendment is effective 
for fiscal years beginning after December 15, 2016, and earlier adoption is permitted. The adoption of this 
amendment  is  not  expected  to  have  a  material  impact  on  the  Company’s  financial  position,  results  of 
operations, cash flow and financial statement disclosures. 

3.  DISCONTINUED OPERATIONS AND EXIT ACTIVITIES 

Discontinued Operations 

As part of the Company’s strategy to evaluate its business segments periodically, management noted that

the  Network  Security  Group  has  incurred  significant  operating  losses  and  its  business  had  not  grown  as 
projected.    In light of the downturn of business in Network Security products the Company determined 
that  a  triggering  event  had  occurred  and  initiated  an  impairment  loss  analysis  on  the  Network  Security 
Group’s long-lived assets using a discounted cash flow approach in estimating fair value as market values 
could  not  be  readily  determined.    In  November  2010,  the  Board  of  Directors  (the  “Board”)  resolved  to 
discontinue the operations of Network Security Group and to liquidate the assets of the Network Security 
Group in due course. The Company has ceased the segment’s operation and has commenced the related 
shutdown activities, most of which were completed in 2011.    The Company did not have any revenue and 
expense from the operations of this business segment in 2015 and 2014.     

The Company determined that the Network Security Group meets the definition of a separate component 
and  the  results  of  the  Network  Security  Group  are  reported  as  discontinued  operations  in  the 
accompanying statements of operations and comprehensive income. 

Exit Activities   

 In December 2014, the Company determined to dissolve the Intelligent Power Group, one of the product 
lines  of  the  Company’s  Integrated  Circuit  Group,  which  comprised  of  the  IC  products  such  as  DC/DC 
controller  ICs,  battery  charger  controllers  ICs,  charger  ICs,  and  LDO  Regulator  ICs.    The  actions  taken  to 
dissolve  the  Intelligent  Power  Group  resulted  in  significantly  reducing  the  developing  activities  of  the 
Intelligent Power products, and terminating the related workforce.   

For  the  year  ended  December  31,  2014,  the  Company  recorded  costs  associated  with  exit  activities  of 
$3,027,000,  of  which  $82,000  and  $2,945,000  were  related  to  a  loss  on  asset  write-off  and  one-time 
employee  termination  benefits,  respectively.  The  Company  determined  that  those  assets  directly 
held/carried  by  the  Intelligent  Power  Group  provided  no  future  benefit  and  recognized  a  loss  on  asset 
write-off, including property and equipment of $24,000, and deferred charges of $58,000. As of December 
31, 2014, one-time employee termination benefits of $2,945,000 were accrued and recorded as accrued 
expenses and other current liabilities on the balance sheet, which had been settled in 2015. 

4. 

 FAIR VALUE MEASUREMENTS 

The Company measures its cash equivalents and marketable securities at fair value.    Fair value is an exit 
price, representing the amount that would be received to sell an asset or paid to transfer a liability in an 
orderly  transaction  between  market  participants.    As  such,  fair  value  is  a  market-based  measurement 
that should be determined based on assumptions that market participants would use in pricing an asset or 
liability.    The  Company  measures  its  cash  equivalents  and  marketable  securities  at  fair  value.  The  Company  also 
determines the fair value of long-term investments and long-lived assets whenever events or changes in circumstances 
indicate the carrying value may not be recoverable.    A three-tier fair value hierarchy is established as a basis 
for  considering  such  assumptions  and  for  inputs  used  in  the  valuation  methodologies  in  measuring  fair 
value: 

Level 1 –    Observable inputs such as quoted prices for identical instruments in active markets; 
Level 2 –    Inputs,  other  than  the  quoted  prices  in  active  markets,  that  are  observable  either  directly  or 

indirectly;   

Level 3 –    Unobservable  inputs  in  which  there  is  little  or  no  market  data,  which  require  the  reporting 

entity to develop its own assumptions. 

Assets and liabilities measured at fair value on recurring and nonrecurring bases were as follows:

As  described  in  note  3,  in  connection  with  the  dissolution  of  the  Intelligent  Power  Group,  property  and 
equipment  and  deferred  charges  with  a  carrying  amount  of  $24,000,  and  $58,000,  respectively,  were 
written  down  to  their  fair  value  of  zero,  resulting  in  an  exit  activities  charge  of  $82,000,  which  was 
included in earnings for the year ended December 31, 2014.     

The Company utilized a pricing service to estimate fair value measurements for the money market mutual 
funds.    The pricing service utilized market quotations for fixed maturity securities that had quoted prices 
in  active  markets.    Fixed  maturity  securities  generally  traded  daily  on  dealer  bids  rather  than  bids 
recorded  on  exchanges.    The  pricing  service  prepared  estimates  of  fair  value  measurements  for  these 
securities using its proprietary pricing applications which included available relevant market information, 
benchmark  curves,  benchmarking  of  like  securities,  sector  groupings  and  matrix  pricing.    Since  most  of 
the fixed maturity securities had maturities of one year or less, the Company believed that the fair value 
would not be materially different from the original purchased cost.    The Company’s fair value processes 
included  controls  that  were  designed  to  ensure  appropriate  fair  values  were  recorded.  Such  controls, 
which  may  be  performed  quarterly  or  when  certain  assets  need  to  be  measured  at  fair  value  on  a 
non-recurring  basis,  include  a  detailed  review  of  methodologies  and  assumptions  and  a  management 
review of valuation. 

The  fair  value  estimates  provided  by  the  pricing  service  for  the  Company’s  investments  were  based  on 
observable  market  information  rather  than  market  quotes.    Accordingly,  the  estimates  of  fair  value  for 
short-term  investments  were  determined  based  on  Level  2  inputs  at  December  31,  2015  and  2014, 
respectively. 

The  fair  value  measurement  in  cost  method  securities  was  determined  based  on  certain  evidential 
financial information.    Please also see discussions in note 9.

In  July  2008,  the  Company  invested  in  preferred  shares  of  Sigurd  Cayman  for  $5,700,000  to  become  a 
strategic partner of Sigurd Microelectronics Corporation (“Sigurd”).    Upon completion of the transaction, 
the Company obtained a 19.54% ownership of Sigurd Cayman.    The Company accounts for the investment 
under the cost method as the Company does not exercise significant influence over operating and financial 
policies of Sigurd Cayman and management of Sigurd holds the controlling interests.    In April 2010, the 
Company  participated  in  another  round  of  preferred  shares  issued  by  Sigurd  Cayman  amounting  to 
$1,500,000.    In September 2015, Sigurd Cayman announced the liquidation of its wholly owned subsidiary, 
Sigurd  Microelectronics  (Wuxi)  Co.,  Ltd.  (“Sigurd  Wuxi”),  whose  sales  and  operations  account  for  the 
majority business of Sigurd Cayman. In view of Sigurd Cayman’s recurring financial losses and its decision 
to  cease  operations  of  Sigurd  Wuxi,  the  Company  determined  that  the  decline  in  fair  value  of  the 
investment  in  Sigurd  Cayman  was  other-than-temporary  and  recognized  an  impairment  charge  of 
$4,835,000 in 2015. The resulting investment which was classified as Level 3 in the fair value hierarchy was 
valued  using  a  discounted  cash  flow  model  considering  the  latest  available  financial  information  which 
primarily consists of cash and time deposits. The valuation inputs primarily included an estimate of future 
cash flows, expectations about possible variations in the amount and timing of cash flows. The significant 
unobservable  input  is  assuming  no  future  revenue  and  cost  associated  with  production  activities.  As  of 
December  31,  2015,  the  Company  held  9,690,445  shares,  which  represented  an  18.88%  ownership  of 
Sigurd Cayman, and the fair value of the investment after impairment was $2,365,000. 

The  Company  invested  in  X-FAB’s  ordinary  shares  in  July  2002.    X-FAB  (formerly  known  as  X-FAB 
Semiconductor  Foundries  AG) 
in 
analog/mixed-signal application. As of December 31, 2015, the Company held 530,000 shares at the cost 
of  $4,968,000  (4,982,000  EURO),  which  represented  a  1.60%  ownership  of  X-FAB.  In  April  2016,  the 
Company  sold  the  entire  X-FAB’s  ordinary  shares  to  a  third  party  company  and  recognized  a  gain  on 
disposal of $413,000.

In  November  2005,  the  Company  invested  in  PVEF,  a  fund  management  company  in  Singapore,  with  an 
investment amount of $585,000 (SG$1,000,000) for 20 units in the placement at SG$50,000 per unit.    The 
Company  further  invested  $357,000  (SG$500,000)  in  June  2010  to  obtain  30  units.    A  portion  of  the 
shares  were  redeemed  by  PVEF  in  November  2012  and  May  2015  at  a  cost  of  $445,000  and  $330,000, 
respectively,  and  the  carrying  cost  of  the  Company  is  reduced  to  $167,000  accordingly.    In  December 
2015, in view of the fund’s liquidation and continuous lower net asset value than the cost, the Company 
determined  that  the  decline  in  fair  value  of  the  investment  in  PVEF  was  other-than-  temporary  and 
recognized an impairment charge of $118,000. The fair value for the fund was estimated based on the net 
asset value of the Company’s ownership interest in the fund. The investment was classified as Level 3 in 
the fair value hierarchy since the fund was redeemable at December 31, 2015. Distributions from fund will 
be  received  through  the  liquidation  of  the  underlying  assets  of  the  fund  or  the  redemption  of  shares 
initiated by the fund. As of December 31, 2015, there were no unfunded commitments and the Company 
held a 5% interest in the fund as of December 31, 2015.

The Company invested in GEM’s preference shares in August 2002. GEM is a multinational semiconductor 
assembly  and  test  company.    On  April  16,  2012,  GEM  signed  a  share  purchase  agreement  with  a  listed 
company in Taiwan which will purchase GEM’s preference share at a price of $0.235 per share to obtain 
approximately 58.4% ownership of GEM.    In respect to this subsequent event, the Company considered 
this a Type I subsequent event and the investment to be other-than-temporarily impaired.    Therefore, the 
Company recognized an impairment loss of $422,000 as of December 31, 2011.    As of December 31, 2015, 
the Company held 333,334 shares at the cost of $78,000, which represented a 0.35% ownership of GEM. 

The Company invested $1,960,000 (NT$62,900,000) in EMC’s 3,468,000 ordinary shares in June 2010. EMC 
is  a  fabless  power  device  design  company  in  Taiwan,  specialized  in  power  semiconductor  process 
development,  and  the  design  of  high  efficiency  power  device  and  system.    In  December  2012,  the 
Company  sold  200,000  shares  in  the  amount  of  $138,000  in  the  process  of  EMC’s  getting  listed  on  the 
Emerging  Stock  GreTai  Security  Market  of  Taiwan.    As  of  December  31,  2015,  the  Company  held 
3,474,854 shares at the cost of $1,844,000, which represented a 10.98% ownership of EMC. 

In July 2013, the Company invested $250,000 (NT$7,500,000) in Verticil, a privately-owned manufacturer 
of  LED  power  modules  and  integrated  lighting  solutions  provider  in  Taiwan.    Based  on  the  recent 
operating  status  and  a  round  of  financing  of  Verticil  in  August  2014,  the  Company  considered  the 
investment to be other-than-temporarily impaired. Therefore, the Company recognized an impairment loss 
of  $83,000  (NT$2,500,000)  in  the  third  quarter  of  2014.    The  Company  sold  the  entire  Verticile  shares 
during the second half of 2015 and a gain of $8,000 was recorded for the year ended December 31, 2015.   

The  Company  invested  in  Etrend’s  ordinary  shares  in  December  2002,  July  2003,  and  March  2004, 
respectively.  Etrend  is  a  wafer  probing,  packing  and  testing  company.    In  August  2007,  Etrend’s  shares 
were  listed  on  the  Emerging  Stock  GreTai  Security  Market  of  Taiwan  and  the  Company  reclassified  the 
investment  in  Etrend  to  available-for-sale  securities.    Etrend  was  successfully  listed  on  the  GreTai 
Securities Market of Taiwan in November 2010.    The Company sold the entire Etrend shares in the stock 
exchange market during the second half of 2014 and a gain of $436,000 was recorded for the year ended

Depreciation  expense  recognized  during  the  years  ended  December  31,  2015,  2014,  and  2013  was 
approximately $1,730,000, $2,548,000, and $3,464,000, respectively.     

As a result of dissolution activities of the Intelligent Power Group, a loss on asset write-off of $24,000 on 
property and equipment was incurred for the year ended December 31, 2014.    Please see discussions in 
note 3. 

In  August  2009,  the  Company  sold  its  land,  located  in  Hsinchu,  Taiwan,  to  a  real  estate  developer  in 
exchange for a portion of the real estate after it is developed, which includes a portion of an office building 
and  a  portion  of  a  parking  lot,  with  a  carrying  value  of  approximately  $8,918,000.    The  Company 
consummated  this  transaction  to  acquire  office  building  space  and  parking  lot  space  for  the  purpose  of 
future operations and business growth.    The Company deferred the transaction gain of $129,000 during 
the construction period.    Since the fourth quarter of 2014, the title of some units of the buildings were 
completed  and  sold  to  the  third  party  and  the  Company  has  realized  the  deferred  gain  of  $106,000 
accordingly.    Considering the Company’s current operating scale and capital requirements, the Company 
leased out three units to a third party in December 2014.    The Company has also sold 5 building units to 
third  parties  since  the  fourth  quarter  of  2014.    As  a  result  of  the  sale  of  building  units,  net  gains  of 
$767,000 and $458,000 were recorded for the years ended December 31, 2015 and 2014, respectively.   

Beginning in November 2015, the Company has negotiated with a third party company to dispose one of 
the three units of the Company’s office building located in China.    A letter of intent has also been signed 
by both parties in January 2016. The Company determined that this transaction meets the criteria of asset 
held for sale and such reclassification was made as of December 31, 2015. In April 2016, an agreement was 
signed by both parties and this transaction is expected to be completed in the second half of 2016.

Deferred charges  are advanced payments for consulting, maintenance, and engineering license contracts 
and  are  amortized  over  the  terms  of  the  contracts  from  2  to  5  years.    Amortization  expense  of  the 
deferred charges for  the years ended December 31,  2015, 2014, and 2013 was approximately $688,000, 
$1,142,000, and $1,162,000, respectively.     

As  a  result  of  dissolution  activities  of  the  Intelligent  Power  Group,  loss  on  asset  write-off  of  $58,000  on 
deferred charges was incurred for the year ended December 31, 2014.    Please see discussions in note 3. 

All land within municipal zones in China is owned by the government.    Limited liability companies, joint 
stock  companies,  foreign-invested  enterprises,  privately  held  companies  and  individual  natural  persons 
must pay  fees for granting of rights to use land  within  municipal  zones.    Legal  use  of  land  is  evidenced 
and  sanctioned  by  land  use  certificates  issued  by  the  local  municipal  administration  of  land  resources.   
Land use rights granted for industrial purposes are limited to a term of no more than 50 years. 

Land  use  rights  are  recorded  at  cost  less  accumulated  amortization.    Amortization  is  provided  on  a 
straight-line  basis  over  the  term  of  the  land  use  rights  agreement  which  is  49.7  years.    Amortization 
expense of the land use rights for the years ended December 31, 2015, 2014, and 2013 was approximately 
$28,000, $28,000, and $28,000, respectively.

The valuation allowance shown in the table above relates to net operating losses, credit carryforwards and 
temporary  differences  for  which  the  Company  believes  that  realization  is  not  more  than  likely.  The 
valuation  allowance  increased  by  $13,000,  $150,000,  and  $515,000  for  the  years  ended  December  31, 
2015,  2014,  and  2013,  respectively.    The  changes  in  the  valuation  allowance  in  2015,  2014,  and  2013 
were primary due to the fluctuations in R&D credits from O2Micro Inc. that could not be utilized.     

As  of  December  31,  2015,  O2Micro,  Inc.  had  U.S.  federal  and  state  research  and  development  credit 
carryforwards  of  approximately  $5,304,000  and  $6,721,000,  respectively.    The  US  federal  research  and 
development  credit  will  expire  from  2022  through  2034  if  not  utilized,  while  the  state  research  and 
development credit will never expire.    Utilization of the research and development credits may be subject 
to  significant  annual  limitation  due  to  the  ownership  change  limitations  provided  by  the  U.S.  Internal 
Revenue  Code  of  1986  and  similar  provisions  in  the  State  of  California’s  tax  regulations.  The  annual 
limitation may result in the expiration of federal research and development credits before utilization.   

To  better  position  itself  for  the  future  growth  phase,  the  Company  considered  the  repatriation  of  the 
earnings  from  subsidiaries  in  Taiwan  and  China  in  the  second  and  fourth  quarter  of  2015.  As  a  result,  a 
deferred tax liability and a withholding tax expenses for the unremitted earnings in Taiwanese and Chinese 
subsidiaries have been recorded for $2,188,000 as of December 31, 2015. 

The  Company  files  income  tax  returns  in  various  foreign  jurisdictions.    The  Company  is  generally  no 
longer subject to income tax examinations by tax authorities for years prior to 2010 because of the statute 
of limitations.   

14.  RETIREMENT AND PENSION PLANS 

The  Company  has  a  savings  plan  that  qualifies  under  Section  401(k)  of  the  US  Internal  Revenue  Code. 
Participating employees may defer up to the US Internal Revenue Service statutory limit amounts of pretax 
salary.    The  Company  may  make  voluntary  contributions  to  the  savings  plan  but  has  made  no 
contributions since the inception of the savings plan in 1997. 

The Company also participates in mandatory pension funds and social insurance schemes, if applicable, for 
employees in jurisdictions in which other subsidiaries or offices are located to comply with local statutes

and  practices.    For  the  years  ended  December  31,  2015,  2014,  and  2013,  pension  costs  charged  to 
income  in relation to the  contributions to these  schemes  were $1,152,000, $1,328,000, and $1,586,000, 
respectively.    The Company adopted a defined benefit pension plan and established an employee pension 
fund committee for certain employees of O2Micro-Taiwan who are subject to the Taiwan Labor Standards 
Law (“Labor Law”) to comply with local requirements.    This benefit pension plan provides benefits based 
on  years  of  service  and  average  salary  computed  based  on  the  final  six  months  of  employment.    The 
Labor Law requires the Company to contribute between 2% to 15% of employee salaries to a government 
specified  plan,  which  the  Company  currently  makes  monthly  contributions  equal  to  2%  of  employee 
salaries.    Contributions  are  required  to  be  deposited  in  the  name  of  the  employee  pension  fund 
committee with the Bank of Taiwan.     

The government is responsible for the administration of all the defined benefit plans for the companies in 
Taiwan  under  the  Labor  Standards  Law.  The  government  also  sets  investment  policies  and  strategies, 
determines investment allocation and selects investment managers. As of December 31, 2015 and 2014, 
the  asset  allocation  was  primarily  in  cash,  equity  securities  and  debt  securities.  Furthermore,  under  the 
Labor  Standards  Law,  the  rate  of  return  on  assets  shall  not  be  less  than  the  average  interest  rate  on  a 
two-year time deposit published by the local banks and the government is responsible for any shortfall in 
the  event  that  the  rate  of  return  is  less  than  the  required  rate  of  return.  However,  information  on  how 
investment allocation decisions are made, inputs and valuation techniques used to measure the fair value 
of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in 
plan  assets  for  the  period  and  significant  concentrations  of  risk  within  plan  assets  is  not  fully  made 
available to the companies by the government. Therefore, the Company is unable to provide the required 
fair value disclosures related to pension plan assets. 

The percentage of major category of plan assets as of December 2015 and 2014 were as follows:

15.  STOCK-BASED COMPENSATION 

Employee Stock Purchase Plan 

In  October  1999,  the  Board  adopted  the  1999  Employee  Stock  Purchase  Plan  (“1999  Purchase  Plan”), 
which was approved by the shareholders prior to the consummation of its initial public offering in August 
2000.    A total of 50,000,000 ordinary shares were reserved for issuance under the 1999 Purchase Plan, 
plus  annual  increases  on  January  1  of  each  year,  commencing  in  2001,  up  to  40,000,000  shares  as 
approved by the Board.    In June 2008, an additional 20,000,000 shares were reserved for issuance as also 
approved by the Board. The 1999 Purchase Plan was subject to adjustment in the event of a stock split, 
stock dividend or other similar changes in ordinary shares or capital structure.   

The  1999  Purchase  Plan  permitted  eligible  employees  to  purchase  ordinary  shares  through  payroll 
deductions, which may range from 1% to 10% of an employee’s regular base pay.    Beginning November 1, 
2005, the 1999 Purchase Plan was implemented through consecutive offer periods of 3 months’ duration 
commencing  on  the  first  day  of  February,  May,  August  and  November.    Under  the  1999  Purchase  Plan, 
ordinary  shares  may  be  purchased  at  a  price  equal  to  the  lesser  of  90%  of  the  fair  market  value  of  the 
Company’s  ordinary  shares  on  the  date  of  grant  of  the  option  to  purchase  (which  is  the  first  day  of  the 
offer period) or 90% of the fair market value of the Company’s ordinary shares on the applicable exercise 
date  (which  is  the  last  day  of  the  offer  period).    Employees  may  have  elected  to  discontinue  their 
participation  in  the  purchase  plan  at  any  time;  however,  all  of  the  employee’s  payroll  deductions 
previously credited to the employee’s account will be applied to the exercise of the employee’s option on 
the  next  exercise  date.    Participation  ends  automatically  on  termination  of  employment  with  the 
Company.    If  not  terminated  earlier,  the  1999  Purchase  Plan  had  a  term  of  10  years.    By  2009, 
10,685,400 ordinary shares had been purchased under the 1999 Purchase Plan.     

As approved by the EGM held on May 30, 2009, the Company adopted the 2009 Employee Stock Purchase 
Plan (“2009 Purchase Plan”) along with the Company delisting from SEHK in September 2009.    The 2009 
Purchase Plan succeeded the 1999 Purchas Plan, and the terms and provisions of 2009 Purchase Plan are 
generally  the  same  as  the  1999  Purchase  Plan.    The  2009  Purchase  Plan  has  a  term  of  10  years,  if  not 
terminated  earlier.    A  total  of  25,000,000  ordinary  shares  were  reserved  for  issuance  under  the  2009 
Purchase  Plan  starting  November  2009.    As  approved  by  the  Annual  General  Meeting  of  Shareholders 
(“AGM”) held on June 22, 2012, additional 15,000,000 ordinary shares were reserved for issuance under 
the 2009 Purchase Plan.    From 2013 to 2015, 16,164,150 ordinary shares had been purchased under the 
2009 Purchase Plan.   

Stock Option Plans 

In  1997,  the  Board  adopted  the  1997  Stock  Plan,  and  in  1999,  adopted  the  1999  Stock  Incentive  Plan.   
The  plans  provide  for  the  granting  of  stock  options  to  employees,  directors  and  consultants  of  the 
Company. 

Under  the  1997  Stock  Plan,  the  Board  reserved  185,000,000  ordinary  shares  for  issuance.    After  the 
completion  of  an  initial  public  offering,  no  further  options  were  granted  under  the  1997  Stock  Plan.   
Under  the  1999  Stock  Incentive  Plan,  the  maximum  aggregate  number  of  shares  available  for  grant  was 
150,000,000 ordinary shares plus an annual increase on January 1 of each year, which commenced in 2001, 
equal to the lesser of 75,000,000 shares or 4% of the outstanding ordinary shares on the last day of the 
preceding  fiscal  year  or  a  smaller  number  determined  by  the  plan  administrator.    As  of  December  31, 
2015,  the  number  of  options  outstanding  and  exercisable  was  722,300  and  722,300,  respectively,  under 
the 1999 Stock Incentive Plan. 

The Board adopted the 2005 Share Option Plan (“2005 SOP”), which was effective on March 2, 2006, the 
date the Company completed the listing on the SEHK.    The adoption of the 2005 SOP also resulted in the 
Board terminating the 1997 Stock Plan and 1999 Stock Incentive Plan. The Company began issuing stock 
options solely under the 2005 SOP for up to 100,000,000 ordinary shares.    As approved by the EGM held 
on May 30, 2009, the number of shares available for issue was increased from 100,000,000 to 175,000,000 
shares.    The  references  to  Hong  Kong  and  Hong  Kong  related  rules  and  regulations  were  also  removed 
along with the completion of the Company’s delisting from the SEHK in 2009.    As approved by the AGM 
held on June 22, 2012, additional 50,000,000 ordinary shares were reserved for issuance under the 2005

SOP.  Under  the  terms  of  the  2005  SOP,  stock  options  are  generally  granted  at  fair  market  value  of  the 
Company’s ordinary shares.    The stock options have a contractual term of 8 years from the date of grant 
and  vest  over  a  requisite  service  period  of  4  years.    As  of  December  31,  2015,  the  number  of  options 
outstanding and exercisable was 176,806,500 and 126,404,750, respectively, under the 2005 SOP. In 2015, 
the Board adopted the 2015 Stock Incentive Plan, which was approved by the Shareholders in July 2015, 
and replaced the 2005 SOP after it expired on March 2, 2016.

The Company calculated the fair value of each option grant on the date of grant using the Black-Scholes 
option pricing model that use the assumptions in the following table.    Risk-free interest rate is based on 
the US Treasury yield curve in effect at the time of grant.    The Company uses the simplified method  to 
estimate  the  expected  life  because  the  options  are  considered  as  plain  vanilla  share-based  payment 
awards.  Expected  volatilities  are  based  on  historical  volatility  of  stock  prices  for  a  period  equal  to  the 
options’ expected term.    The dividend yield is zero as the Company has never declared or paid dividends 
on  the  ordinary  shares  or  other  securities  and  does  not  anticipate  paying  dividends  in  the  foreseeable 
future.

Share Incentive Plan 

The Board adopted the 2005 Share Incentive Plan (“2005 SIP”), which was effective on March 2, 2006, the 
date  the  Company  completed  the  SEHK  listing.  The  2005  SIP  provides  for  the  grant  of  restricted  shares, 
RSU, share appreciation rights and dividend equivalent rights (collectively referred to as “Awards”) up to 
75,000,000  ordinary  shares.    As  approved  by  the  EGM  held  on  May  30,  2009,  the  number  of  shares 
available for issue was increased from 75,000,000 to 125,000,000 shares.    The references to Hong Kong

Company’s  delisting  from  the  SEHK.    As  approved  by  the  AGM  held  on  June  22,  2012,  an  additional 
62,500,000  ordinary  shares  were  reserved  for  issuance  under  the  2005  SIP.  Awards  may  be  granted  to 
employees, directors and consultants.    The RSUs vest over a requisite service period of 4 years. In 2015, 
the Board adopted the 2015 Stock Incentive Plan, which was approved by the Shareholders in July 2015, 
and replaced the 2005 SIP after it expired on March 2, 2016.

16.  EARNINGS (LOSS) PER SHARE 

Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number 
of  ordinary  shares  outstanding  during  the  period.    Diluted  earnings  (loss)  per  share  is  calculated  by 
dividing  net  income  (loss)  by  the  weighted  average  number  of  ordinary  and  dilutive  ordinary  equivalent 
shares outstanding during the period, using the treasury stock method for options. 

A  reconciliation  of  the  numerator  and  denominator  of  basic  and  diluted  earnings  (loss)  per  share 
calculations was as follows:

Certain  outstanding  options  and  RSUs  were  excluded  from  the  computation  of  diluted  EPS  since  their 
effect would have been anti-dilutive. The anti-dilutive stock options excluded and their associated exercise

United States for the years ended December 31, 2015, 2014, and 2013, respectively.     

The Company, as a normal course of business, is a party to litigation matters, legal proceedings, and claims. 
These  actions  may  be  in  various  jurisdictions  and  may  involve  patent  protection  and/or  infringement. 
While  the  results  of  such  litigations  and  claims  cannot  be  predicted  with  certainty,  the  final  outcome  of 
such  matters  is  not  expected  to  have  a  material  adverse  effect  on  its  consolidated  financial  position  or 
results of operations. No assurance can be given, however, that these matters will be resolved without the 
Company becoming obligated to make payments or to pay other costs to the opposing  parties, with the 
potential for having an adverse effect on the Company’s financial position or its results of operations. No 
provision for any litigation has been provided as of December 31, 2015 and 2014.

Long-term  investments  are  in  privately-held  companies  where  there  is  no  readily  determinable  market 
value  and  are  recorded  using  the  cost  method.    Since  they  entail  an  unreasonable  high  cost  to  obtain 
verifiable fair values, fair value is not presented.    The Company periodically evaluates these investments 
for  impairment.    If  it  is  determined  that  an  other-than-temporary  decline  has  occurred  in  the  carrying 
value, an impairment loss is recorded in the period of decline in value.     

20.  SEGMENT INFORMATION   

In September 2008, the Board approved a plan to transfer Network Security business to O2Security along 
with  its  Series  A  preference  shares  financing.    In  anticipation  of  the  business  transfer,  management 
identified two reportable segments, including Integrated Circuit Group and Network Security Group. The 
Integrated  Circuit  Group’s  core  products  and  principal  source  of  revenue  are  its  power  management 
semiconductors.    These  semiconductor  products  are  produced  with  digital,  analog,  and  mixed  signal 
integrated circuit (“IC”) manufacturing processes.    The Network Security Group’s system security solution 
products  include  support  for  VPN  and  firewalls,  which  provide  security  functions  between  computer 
systems  and  networks,  including  the  transmission  of  data  across  the  Internet.    In  November  2010,  the 
Company determined to discontinue the Network Security Group.    Please see discussions in note 3.   

The  Company  does  not  identify  or  allocate  assets  by  operating  segment,  nor  does  the  chief  operating 
decision  maker (“CODM”) evaluate operating segments using discrete asset information.    The Company 
does not have inter-segment revenue, and, accordingly, there is none to be reported.    The Company does 
not  allocate  gains  and  losses  from  interest  and  other  income,  or  income  taxes  to  operating  segments.   
The accounting policies for segment reporting are the same as for the Company as a whole.   

Operating segment net sales and operating loss, including the discontinued Network Security Group, were 
as follows:
