Code of Conduct

An impeccable image is priceless. In our Company, we have developed and use a corporate Code of Conduct – a set of rules outlining NIS’s ethical standards in all business areas.


As the largest company in the Republic of Serbia and one of the regional energy leaders, in addition to the high-quality products offered to its partners and customers, NIS can also take pride in a modern business standard. Our commitment to our values and adherence to ethical standards are the components of NIS’s success. Our image is built on these principles.

A Code of Conduct is the principal code for every modern company, and each and every employee must abide by it, without exception.

The NIS Code of Conduct establishes ground rules and behavior standards, defining relationships with colleagues, clients, business partners, government and local authorities, competitors and the public

The principles enshrined in our corporate Code of Conduct are solid and long-lasting. They leave no room for ambiguity and give clear recommendations for making balanced ethical decisions in various situations.

Ethical questions

The Business Ethics Code is designed to help employees resolve all potential dilemmas they might encounter in the daily performance of their tasks in terms of potentially corrupt practices, protection of information privacy, abuse of Company assets, etc. The Company organizes trainings and pays great attention to this issue in order to enable NIS to continue being the best example, proving that ethical operation is a prerequisite, not a choice.

During 2016, the Company constantly analysed and evaluated the fundamental risks related to corruption in all organisational units. In addition, permanent monitoring of corruption indicators was undertaken. These were mainly in the areas of procurement of goods and services, in transactions with customers as well as through the verification of candidates for employment and appointments to managerial and other leadership positions in the Company. This also applies to the process of verifying economic entities when entering into contractual relations and to harmonisation of contractual and normative and methodological documents.

NIS is heavily focused on the prevention of any illegal and harmful practices

Trainings for new employees have been conducted in NIS on “Fight against corruption and organised crime“ which points to the basic elements of implementation of the anti-corruption policy, preventively acts against corruption, discloses developed corruption capacities, and provides help to entities to be able to recognise elements of corruption.

With all business partners with which NIS concludes agreements, NIS also concludes the Agreement on Anti-Corruption Behaviour. In cases when a business partner refuses to sign the Agreement on Anti-Corruption Behaviour, measures and actions are taken for establishing real reasons that led to the non-signing of the Agreement.

NIS Business Ethics Code that is particularly directed to the promotion of anti-corruption in the Company and operation of the SOS line provide an opportunity both for the employees and for stakeholders to respond in cases of non-compliance with defined rules. In addition, a special phone line and e-mail address were introduced for reporting on corruption cases in the Company.

Relations with suppliers

One basis for maintaining NIS competitiveness in the market is successful cooperation with suppliers. This includes successful completion of procurement processes, i.e. timely provision of the materials and services necessary for implementing production and business processes in the Company.

The main principles guiding the implementation of  procurement processes are:

• Process cost-effectiveness and efficiency, and

• Bidder competitiveness and equality

These principles and business logic are always accompanied by the standardisation of business processes through adopted documents: rulebooks, policies, standards and instructions. NIS prioritises the competitive selection of suppliers and contractors. In cases where the business situation requires a noncompetitive mode of selection, this must be explained by the procurement initiator.

The competitive selection is based on the analysis of alternative offers and the selection of a supplier that submitted a technically acceptable and favourable offer in terms of price, delivery/ completion time, warranty period, securities or additional benefits.

Legal issues

In 2016, there were no inspection procedures caused by noncompliance with legal regulations, lack of provision of product information labelling and/or of the services of the Company initiated.

Neither were there any court proceedings or claims against the Company, i.e. no cases where products and services would impact the safety and health of consumers, nor were there any cases of non-compliance with regulations or proceedings regarding breaches of customer privacy.
