Message from the President
Last year was a year when we were forced to realize the helplessness of mankind in front of great natural forces
which caused such disasters as the Great East Japan Earthquake and flood in Thailand. We felt more than everthat what we needed was a social system which was resilient to natural disasters.
As a developer and manufacturer of equipment related to electricity, we believe that we can contribute to energy
saving for the entire society through business activities by encouraging activities to reduce environmental burdens
generated from our business activities as well as by developing and introducing highly energy efficient productswith reduced electrical loss.
We also believe that it is our mission and responsibility to pass on this precious earth's environment in healthy
conditions to our next generation.
We will promote activities to reduce environmental burdens further and aim to become a company on which ourcustomers would say "we could like to use Cosel products" for both our quality and environment.
Keeping the idea of protecting global environment and passing it on to the generations to come to our heart, we
would like to steadily advance as a trusted company. Please feel free to contact us with your honest opinions andinput for our further improvement.

Many electric components including semiconductor devices are used in electronics products such asindustrial and commercial equipment. For these equipment to operate, electrical power delivered tofactories and households needs to be converted from alternating current (AC) to direct current (DC).
Our regulated DC power supplies make this possible.
In particular, switch mode power supplies are our main products. They are used in many electric
devices such as information and telecommunications, medical and FA equipment because they arecompact, light weight and highly efficient.
We can say that switch mode power supplies are the hearts of these equipment and hold a key to the
future of the electronics era.
We will continue our dialogue with new technologies and make highly reliable products which will help
build the future of electronics.

Management System
Legal Compliance and Others
We are keeping abreast of changes and revisions of the environmental laws and regulations which
we need to abide by in our environmental management activities monthly. If necessary to apply to us,
we inform it to all employees through our internal Environmental Committee,
Regarding othe requests, we input them in our computer system so that all the emploees and therelevants can refer to for their references every time in need.
We are reflecting all the laws, regulations, requirements and evaluation results in our internal rules,
regulations and standards and evaluating our legal compliance every year to make sure we do not
violate any laws, regulations or requirements.

Environmental Audit
We are conducting an environmental audit every year to confirm our compliance with ISO14001,
implementation and performance status.
Our internal auditors form a team comprising of those who have taken internal and external audit
trainings and deemed qualified to audit each department.
Currently, there are 25 internal environmental auditors.
Each auditor reports audit results including areas of improvement to each department manager.
Each department reviews their activities and engage in activities for continuous improvement.
In FY 2011, 13 non-compliance cases were observed. Corrective actions were completed for all 7
cases.

Prevention of Accidents
We have developed a "Environment-related Equipment Map" which shows where those environmentrelated equipments are in Head Office and Tateyama Plant to prevent and detect accidents caused bythem abnormally.
If we determine that a certain equipment needs more control, we check if the procedure set forth in
the case of emergency are put in place, and if the regular maintenance and measurement are
conducted. In this manner, we are well-prepared to cope with an unexpected incident.
We have received no complaints from our stakeholders about the environment-related issues.
We have confirmed that all our measured environmental data, including vibration and noise level, do
not exceed legal and regulatory maximum limits.
(Example) We are checking kerosene and oil tanks every month to see if there is any cracks or
damages to prevent soil contamination.

Introduction of Power Monitoring System

Power Monitoring System〜 Making Power Consumption Visible 〜

To raise awareness toward energy saving, we haveintroduced a power usage monitoring system throughwhich we can check power usage status on our intra-net.
With this system, we can check power usage status of afactory by area group and by equipment. We can also see
our past power usage trend by year, month, day, time or in
30 minute increments. These information can be displayd
in graphs which are automatically created.
This system enables us to understand our power usage
status of our workplace and equipment. It is expected that
this will raise awareness toward energy saving.
We will make use of this system and facilitate energy
saving measures.

Highlights of Our Environmental Activities
Establishing Eco Products: Environmentally Friendly Products and its Symbol
We have developed a new internal evaluation system on environmental burdens in order to provide
our customers with information on our products and our efforts to promote the development ofenvironmentally friendly products since 2010.
We are looking at the following 3 items in evaluating our products to reduce their environmental
burdens.
(1) Environmental burdens generated when our products are in operation at customers' site(2) Environmental burdens generated when our products are manufactured at our factories(3) Environmental burdens generated when materials and components we purchase are
manufactured.
Based on the above 3 items, we set our own criteria to certify and register products which satisfy
our criteria as "Eco Products." These Eco Products are highly efficient in reducing environmental
burdens. To promote Eco Products, we developed the following symbol which represent Eco
Products.

Cosel Co., Ltd. Eco Product Symbol

We will proactively expand our Eco Products to create an environmentally friendly low-carbon
recycling-oriented society and to continue to grow with our customers.
This symbol mark is used in our product catalogue issued in FY2011 on pages covering Eco
Products to provide information to our customers.

Highlights of Our Environmental Activities
Reducing Environmental Burden in Production Floor:〜Reducing Power Consumption of Soldering Pots〜
57% of power consumption by production equipment at our Tateyama Plant is accounted for by ouruse of soldering pots.
Therefore, in FY2010, we tried to reduce power consumption of soldering pots and achieved about
20% reduction by lowering power consumption in the pre-heater area.
In FY2011, we took the following three measures to reduce power consumption in the pot area.
(1) Cover the top surface of the pots with insulating material during the night(2) Cover the top surface of the pots with insulating material during lunch break(3) Partially cover the pots with insulating material during production hours
With these measures, we were able to reduce power consumption by the soldering pots at
Tateyama Plant about 15%.
In FY2011, we took these measures for our 11 internal soldering pots. In FY2012, we will expand
these measures to soldering pots at our subcontractors.

Covers of Soldering Pots

Reducing Environmental Burden in Production Floor:〜Culling of fluorescent light〜
We culled 23% of the fluorescent lights which were always on
because we concluded that culling them would not cause any problem.

Controlling Environmentally Unfriendly Chemicals
EU RoHS Directive (*1) came into effect on July 1, 2006.
Cosel had achieved 100% compliance with RoHS Directive inFebruary, 2006 (*2).
REACH(*3) and PFOS came into effect in FY2007 and
FY2008, respectively. Requirements to control environmentally
unfriendly chemicals became even stricter. We haveestablished the systems to control environmentally unfriendly
chemicals and using these systems so that environmentally
unfriendly chemicals are not used in our products.

Green Procurement

Supplier Management

At Cosel, we are facilitating "Green
Procurement" in which we procure environmentallyfriendly components and materials in order todeliver environmentally friendly products to ourcustomers.
We have defined "prohibited materials,""materials targeted for elimination" and "materials
targeted for reduction" for components andmaterials which comprise our products. By doing
this, we can prevent the entry of environmentally
unfriendly chemicals into our products.

We are evaluating the risk of use ofenvironmentally unfriendly chemicals by our
suppliers and ranking them at 3 levels.
This ranking is used for the "Measurement ofEnvironmentally Unfriendly Chemicals ofPurchased Materials" and "Audit of Suppliers'
Management of Environmentally Unfriendly
Chemicals." This ranking is reviewed once every
year.
Under this system, we audit and review how
environmentally unfriendly chemicals arecontrolled by high risk suppliers and how highrisk components and materials are controlled bysuppliers. We also facilitate registration of highrisk suppliers, materials and components.

Education on Environmentally
Unfriendly Chemicals(*1)What is RoHS Directive?
RoHS Directive is an EU directive that will
restrict the use of certain hazardous materials
in electrical and electric equipment. The useof six substances, mercury (Hg), cadmium(Cd), lead (Pb), haxavalent chromium (Cr6+),
polybrominated biphenyls (PBB),
polybrominated diphenyl ethers (PBDE), will
be prohibited from July, 2006.

In FY2006, we conducted an educational
campaign on environmentally unfriendly chemicals.
Not only people working at our headquarters andTateyama Plant, but also people who are involved
with Cosel's products as our contractors and attransportation companies also participated in our
test and training sessions.
Using a training material developed by ourdepartment which is responsible for environmental
issues, training sessions were held by department
and tests were given to participants to check theirunderstanding about environmental issues. This
enabled them to deepen their understanding of theobjectives and the importance of managing
environmentally unfriendly chemicals as well asactivities taken by Cosel.

(*2) Excluding Maintenance Items(*3) What is REACH?
REACH is an regulation in which
manufacturers or importers of chemical
substances are obliged to register andevaluate chemical substances inmanufacturing or importing them and, in thecase of chemical substances of very highconcern, an authorization from relevant
authorities is required and high risk
substances are subject to limitation including
ban. REACH entered into force in June 2007.

Controlling Environmentally Unfriendly Chemicals
New Components, New Products and Mass Production Management
Since FY2006, we have been conducting fluorescence X-ray tests (*4) by target measurement area
to prevent the entry of environmentally unfriendly chemicals into our products. The fluorescence X-ray
test allows us to confirm and verify whether or not a component is complying with our "Green
Procurement Standards."
The evaluation is performed at the following 3 levels.
We have four X-ray fluorescence instruments in total, two units at our headquarter plant and anothertwo at our Tateyama plant.
New Product Launch

Acceptance of Purchased Components

In the past when we adopted a new component,
we conducted a "Quality Evaluation" to preventthe use of defective components. However, we
decided to conduct fluorescence X-ray tests formass production components to check thepresence of environmentally unfriendly
chemicals in newly adopted components. Test
results are compared to the data about
environmentally unfriendly chemicals which aresubmitted from suppliers before components are
officially registered.

We also conduct fluorescence X-ray tests by target
measurement area when we accept purchased
components.

After Shipping Mass Production Products
After we ship mass production products, we evaluate
the presence of environmentally unfriendly chemicals
to make sure that Green Procurement Standards are
met on an ongoing basis, in addition to ourlongstanding electrical quality and mechanical quality
evaluations.

(*4)What is fluorescence X-ray test?
It is an analytical method in which
information on the existence of an atom isacquired based on the wavelength of a
specific X-ray and the intensity of the energyof the X-ray which is generated when X-ray isirradiated to an atom which comprisemolecules.

Fluorescence X-ray Instrument

Management of Production Lines
In order to prevent the entry of environmentally unfriendly chemicals into our products, RoHScompliant products and non-RoHS-compliant products are manufactured in separate lines on our
production floor by using separate equipment, jigs and tools.
Equipment, jigs and tools for soldering process are identified by signs and labels as shown in thefollowing pictures.

Environmental Conservation Activities
1．Energy Saving
87% of the energy Cosel consumes is electric power. Since the inception of the Company, all our
fluorescent lamps at our shop floors and offices have had pull switches to reduce the amount of
power consumed. We are making sure that lights are turned off during breaks and when not in use.
Furthermore, all the personal computers used at Cosel are set in the energy-saver mode and ourmonitors are automatically turned off when not in use. We are always taking small but importantmeasures.

●Cutting Down Power Consumption of Computers
Entire company has adopted a power-saving configuration inwhich a monitor goes off and a computer goes to a stand-bymode when it is not in use for a certain period of time.
Power switches are provided for each computer or for eacharea so that when somebody goes home, he or she can turnoff the power to reduce power consumption of computers not
in use.

2．Use of Renewable Energies
・FY2002 60kw solar power generator was installed at the rooftop of the new headquarters building

3．Reduce● Reduction of Use of Air Cap Bags for Packing
Air cap bags were used when we shipped transformers
and sheet metals, etc. to contract manufacturers. Oncepackages were opened at contract manufacturers' site, theair cap bags were disposed of as industrial waste.
We reduced the use of air cap bags by changing our
packing methods using reusable Tupperware andcontainers.
Unpacking at contract manufacturers' site also became
more efficient.
(This is one example of our QC circuit activities)

Environmental Conservation Activities●Elimination of Styrofoam
We had been using styrofoam as a buffer material for the shipment of our products because it
was cheap and excellent to protect our products. After being used, it had been discarded as theindustrial waste.
We have replaced plate-shaped styrofoam with cardboards and small styrofoam balls withbiodegradable resin in order to reduce industrial wastes.

4. Reuse●Reuse of Tape Reels and Semiconductor Sticks
We use chips to assemble power supplies. These chips are shipped from manufacturers reeled up
onto plastic reels.
When chips are used up, the reels are left, which used to be discarded as industrial waste ofstabilized type. Some semiconductors come in plastic sticks when shipped from manufacturers.
These sticks had been discarded once semiconductors were used up just like the reels.
Because they do not get deformed or worn after use, we have changed our procedures to reuse
them by having manufacturers collect them after use.

● Reuse of Used IPA
We use isopropyl alcohol (IPA) as a diluent for
fluxes which are used in soldering our products.
We also use IPA for cleaning of jigs and tools.
In 2010, we introduced IPA recovery equipment
to recover used IPA and reuse it . As a result, wewere able to reduce the amount of chemical
substances.

Regenerated IPA

5．Recycle●Recycling of Waste Products andDefective products, unusable bottom
plates and dummy circuit boards thatwere cut off in production processes
had been discarded as industrial waste.
Now we are dividing these wastes
into metals and plastics, etc. before
disposing them so that they can beused as ingot and furnace combustion
improver.

Many types of wastes are generated in our businessactivities. Many of them are recyclable, if we segregate
them properly.
We at Cosel, Environmental Committee andBeautification and Recycling Committee are working
together in such activities as making sure wastes areproperly separated and emissions are reduced.
In FY2011, we called for to completely separate items
brought by manufacturing and distribution
subcontractors. As a result, we were able to reduce
the amount of waste materials by about 20% from thatof the previous year.
In FY2011, we have introduced an electrical manifest
for some of the waste materials. We expect this will
provide us with better compliance and administrative
efficiency.

Chairman ofEnvironment Committee
Yutaka Tamou"Environmental Committee is working on thefollowing 3 major activities.
(1) Reduction of CO 2(2) Improvement of Recycling Rates(3) Compliance with Laws and Regulations
In this fiscal year, we created our internal eco
mark criteria for CO 2 reduction to improve
conversion efficiency of our new products.
Most of our products are power supplies andtheir conversion efficiency directly affects
power consumption. Therefore, higher
efficiency is always needed.
We will continue our efforts with a focus on
making our products highly efficient."

Trend of Electrical PowerAs we mentioned before, 84% of our CO2 emission comes from electrical power consumption. In
order to reduce this, our Environmental Committee is playing a central role in implementing many
activitie.
As for our total energy use (crude oil equivalent) as a business operator under the Law Concerning
the Rational Use of Energy was 1,268kl , which was not subject to notification requirement .
However, it is expected that our energy use will exceed the 1,500kl criteria within several years.
Therefore 2 employees took the Energy Management Training in FY2010.
We have also confirmed that we are not specified consigner as defined by Law Concerning the
Rational Use of Energy.

3. Amount of Environmentally Unfriendly Chemicals
Among chemical substances handled by Cosel, Class I Designated Chemical Substances whose
handling amounts are subject to notification requirement with PRTR are "lead and its compounds."
However, lead solder which falls under "lead and its compounds" is not subject to the notification
requirement because we have already changed all of our solder to lead-free solder.

Improve environmental awareness
Visiting Recycling Company with
Plant TourIn November, ten members of the Beautification
Recycling Committee from our headquarters plant andTateyama plant visited a recycling company to which we
subcontract plastic recycling.
Plant tour was given to deepen our understanding
about waste separation and to confirm how plastics arerecycled.

Application Standard Design Dept.
Takaki Ueda
"This was my first time visiting therecycling plant, which made me realize
once again how important recycling is.
I have had a vague understanding
about how to separate waste items, but
I would like to completely understand it
going forward and would like to be able
to separate waste items correctly andencourage people around me to do thesame."

Segregate plastic bottles
Beverage bending machines are installed in our
premises. Used plastic bottles are separated into
exterior films, caps and bottles (main bodies) before
being discarded.
We are trying to improve environmental awarenessthrough an easy-to-do environmentally friendly activity.

Encouraging taking Eco Test: Developing People who Work on Environmental Issues
Eco Test (officially known as Certification Test forEnvironmental Specialists) is a certification test run by the
Tokyo Chamber of Commerce in order to develop people with awide range of knowledge who can play a leading role in tacklingenvironmental issues and facilitate the realization of asustainable society where we can protect environment
and achieve economic growth at the same time.
Cosel's employees started to take the test from the 6th test
and 41 of them have passed the test so far.
We are encouraging our employees to take the test by
subsidizing a test fee and making those who passed the test
eligible for certification reward monay.
We will continue this effort in FY2012.

Social Contribution
JEITA Toyama District Manufacturing ClassOn June 2, 2012 (Saturday), “5th JEITA Toyama District
Manufacturing Class" was held at Cosel. 25 male andfemale students in grades 5 and 6 from nearby 4
elementary schools participated in the class and engaged
in an electrical engineering project under the theme of"Let's create Radios from Plastic Bottles."Cosel has been a part of this class since the 1st class. In
the 5th class too, our employees served as instructors andgave students guidance.
Children seemed to have struggled with unfamiliar tasksof assembling and soldering, but we received such
feedbacks as "I was surprised that a radio could be madefrom simple things," "It was a learning opportunity and I got
to experience something I couldn't get to experience atschool, " "I would like to participate again because it wassuch a rare experience."※What is JEITA?
Japan Electronics and Information Technology Industries Association.
An organization composed of manufacturers and sellers of such products as electrical and electronic equipment,
electronic devices, electronic components, electronic materials and software.

Cosel Cup Challenge Super Kids
This is our 24th anniversary since we became a special
sponsor for a sport event for boys and girls of grades 4
through 6 hosted by a local TV station.
About 295 children in Toyama prefecture participatedin 5 events ranging from 100-meter sprints, ball throwing,broad jump, zigzag dribbling and swimming.
It became a sparkling day as children competed, family
and friends cheered for them.

Fund-raising Activities
Proceeds from the sales of our internal bazaar and donation from our employees are donated to Toyama
Prefecture Cooperative Donation Society. Donation amount is approximately 100,000 yen per year, which is enoughto buy a wheelchair for the disabled or elderly.
The donation can be also applied to home-based service, volunteer training, accident prevention programs forchildren and fostering and nurturing of young people.
In FY2008, we sent about100 spoiled postcards to National Federation of UNESCO Associations in Japan. The
spoiled postcards are replaced with new stamps and then sold. The proceeds of the sales of these new stamps is
donated.
The donation is used for the World Terakoya Movement, a program for people who had not been fortunate to haveeducational opportunities.

Work and Life Balance
It is very challenging to raise children in single or dual-income families. This is one of the factors which
invited declining birth rates and decreasing population of children. In this environment, one of the social
responsibilities of businesses is to "support life and work balance" for their employees.

【Promoting the use of shorter work hours
for child care system】
Employees who are raising children in the 3rd
grade or younger (as of the end of March of a fiscal
year) can work shorter hours within the prescribed
hours under our flexible work hour system.
General Affairs Dept.
Yuka Nakamura【Encouraging Employees to Use Planned

Our internal rule stipulates that we have to use atleast of 2 days of paid day off every half-year term.
By working efficiently, having good communication
with our bosses and colleagues and using paid days off
in a planned manner, we would like to achieve a goodlife-work balance and personal development andfreshen up ourselves.

25" I have shorter work hours. I come in 30
minutes later and leave office 30 minute
earlier. I am so grateful that I am having
shorter hours because this gives me moretime to spend with my children.
I am trying to pay more attention to taskprioritization than before and get things
done on time within a limiting work hours.
