International Financial Reporting Standards

Integrated risk management system

ISO 14001 Standard
International standard for environmental protection that sets requirements for environment management quality and is used to work out legally compliant environmental policies. The standard regulates environmental aspects of corporate activities that are controllable and require monitoring. This is a voluntary standard that does not supersede legislated requirements

ISO 50001 Standard
International standard established by the International Organisation for Standardisation to manage power systems that specifies requirements for establishing, implementing, maintaining and improving an energy management system, whose purpose is to enable an organisation to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy use and consumption.

ISO 9001 Standard
International standard for quality management systems. It establishes the requirements for the quality management system that may be used internally by organisations for the purpose of certification or concluding contracts. The standard aims to make the quality management system effective while meeting customer demands.

ISO/TS 16949 Standard
International industry standard as well as technical specifications established by the International Organisation for Standardisation. The standard defines the quality management system requirements for enterprises that design, develop, produce, install and service automotive-related products.

The price/earnings ratio that is equal to the ratio of a company’s market capitalization versus its annual earnings. One of the main indicators used for a comparative assessment of the investment appeal of joint-stock companies.

Polymer modified bitumen

Purchasing managers index that reflects the condition of a certain industry or the economy or provides a competitive assessment

Possible Reserves
Unproven reserves, which are less likely to be extracted than probable reserves, based on the analysis of engineering and geological data. There must be at least 10% probability that actual production will be equal to or more than the estimate of proven, probable and potential reserves

Premium market segments
High-margin market segments: small wholesale, own chain of filling stations, sales of jet fuel, bitumen, oils and lubricants, bunkering

Primary Refining
Crude oil distillation using atmospheric vacuum devices. Crude oil enters the distillation columns to undergo an atmospheric pressure distillation process, which splits it into a number of fractions: light and heavy gasoline fractions, kerosene fraction, diesel fraction, and fuel oil as a residue. The quality of the obtained fractions does not meet standards for marketable petroleum products, so the fractions must undergo further(secondary) refining

PRMS International Standard
International classification and estimate of hydrocarbon reserves by the standards of the Petroleum Resources Management System (PRMS). These standards include not only the estimate of hydrocarbon reserves, but also provide the estimate of the commercial practicability of extraction and the justifiability of its availability. The period of economically viable reserve development (period of validity of the development license) is taken into account as well

Probable Reserves
Unproven reserves, which are most likely to be extracted based on the analysis of engineering and geological data. There must be at least a 50% probability that actual production will be equal to or greater than the estimate of proven and probable reserves

Proven Reserves
Quantities of liquid, gaseous and solid hydrocarbons, which, according to engineering and geological information, are most likely to be produced by industrially available methods from known deposits starting from a specific date, under the existing economic conditions, with generally accepted operating techniques, and in compliance with applicable effective national regulations
