Intellectual Capital of a Trading Company: Comprehensive Analysis Based on Reporting

: The study is devoted to the analysis of the e ﬃ ciency of use and the e ﬀ ectiveness of disclosing the intellectual capital (IC) of a trading company operating in the market of the Russian Federation. The subject of the research is an assessment of the quality of disclosure of information about the IC company involved in the creation of ﬁnancial results of activities and the growth of the company’s value. The study examines the assessment of IC and the search for links between the involvement of IC in the formation of the ﬁnancial result of a trading company and the degree of its reﬂection in the company’s annual reports. Methods of using intellectual value-added coe ﬃ cients (VAIC) such as the trademark logo (written as ™ ), Calculated Intangible Value (CIV) and content analysis of the company’s annual reports are used to assess the IC and its elements. The inﬂuence of IC and its components, on the ﬁnancial results of a trading company are also investigated and calculated using various methods. It is shown that there are no statistically signiﬁcant relationships between the assessments of IC and its elements obtained using ﬁnancial ratios, and those obtained using content analysis. This indicates that the opinions and assessments of the heads of a trading company regarding IC are formed regardless of the size of IC involved in the formation of economic results and testiﬁes to the absence of an e ﬀ ective investment management policy in the studied company. Some of the results obtained conﬁrm the trends in IC structures previously observed for companies in other industries. The results also indicate that the existing system for preparing annual reports does not su ﬃ ciently consider the size, dynamics and e ﬃ ciency of using the intangible assets of a trading company. The results of this study are likely to be useful to management and academics.


Introduction
Research on intellectual capital came to the fore in economic research at the end of the 20th century. Lev called the emergence of the concept of intellectual capital "the main economic event of the late XX and early XXI centuries" [1]. This attention by researchers towards the new economic categories of "intellectual assets" and "intellectual capital" was due to several factors.
First, at the end of the 20th century, annual investments in intangible assets in the corporate sector were at first equalized, and then began to exceed investments in tangible assets [1][2][3], while a significant part of the market value of companies is still not reflected in any way in the balance sheets

The Concept and Essence of IC
Intellectual capital (IC) is a complex economic concept consisting of two terms reflecting its features. The leading concept in this phrase is capital. Capital is a complex economic concept, the phenomenon of which is manifested in its constant movement and interaction with other factors of production [21]. Attempts to use a static approach for the concept of capital, as a rule, significantly narrow down its understanding and do not reveal all the features of capital as an economic category [22].
IC is a special type of capital, which, along with ordinary capital, has become one of the most important factors of production since the late 1970s. The reason for this was the development of a post-industrial society [23,24], which is characterized by the dominant role of theoretical knowledge and the expansion of the service sector relative to the industrial sector. According to D. Bell, knowledge is becoming the leading source of surplus value in post-industrial society, just as labor and capital were the leading sources of surplus value in industrial society [25].
In the modern sense, IC is an intangible asset involved in creating value together with other assets by transforming them into other intangible resources, or into material resources in order to maximize the current value of the company from the point of view of owners and stakeholders.
In our opinion, the definition proposed in [26] is deeper, where the intellectual capital of a company is understood as resources and abilities that are strategic in nature, difficult to imitate and affecting the formation of unique capabilities of a company.
IC, as a new factor in the development of the economy of companies, has several features that make it unique. These features include the following: • intangible assets that form the basis of intellectual capital, unlike physical assets, do not have a material embodiment (it is important not to confuse tangible assets with their physical carriers, which allow them to be stored and used in activities), which means certain mechanisms are required for their effective use [3]; • the elements forming intellectual capital have "partial exclusion" [3], which means there is an absence of mechanisms for complete control as well as for ensuring certainty and the protection of the company's intellectual capital property rights, which leads to the problem of accounting for these assets in corporate balance sheets; • non-marketability of elements of intellectual capital, which is due to their practical lack of tradability in the markets, and, as a consequence, the lack of a basis for assessing these elements, incomplete rights to these intellectual assets as well as high market asymmetry (this factor also causes a higher vulnerability for companies with a high intellectual capital) [11].
In addition to the features discussed above, the authors would like to note several features that, as a rule, are not considered by researchers. In the modern concept of the resource approach, the resource advantage is ensured, first, in the advantage in intellectual resources (the importance of the advantage in material resources decreases due to the expansion of access to the most advanced equipment and technologies and the development of telecommunication technologies). Other notably features are: • the duality of the nature of intellectual capital, which is due to the fact that, from the point of view of the resource concept, it acts on the one hand as a resource (factor), and on the other hand, as an "organizational ability" (how the IC is structured, ordered and involved in the company's activities), which solves the problem of not only efficient production, but also the problem of effective reproduction (both conventional and extended) [27,28]; • the need to solve problems of not only production but also reproduction (including extended) leads to the emergence of conflicting requirements for intellectual capital, its structure and individual elements, for example, to the composition and characteristics of the company's personnel [27,28]; • high uncertainty in the lifespan of certain elements of intellectual capital, which, on the one hand, is due to the high information asymmetry between those who use intellectual capital and those who try to copy it, and on the other hand, the rapid obsolescence of elements of intellectual capital, that is, there are no clear criteria for determining the time during which an element of intellectual capital retains its advantages.
In this regard, it is obvious that the disclosure of information about a company's intellectual capital reduces uncertainty and helps to increase investor confidence. This can explain the success of such a tool for working with IC as Edvinson's "Scandia Navigator" [9], which, acting as an innovation, allows external agents to reduce the degree of uncertainty. At the same time, we would also like to note that in the future will be impossible to exclude manipulations with indicators and indicators of intellectual capital. The lack of standards for measuring and presenting information about intellectual capital to external users can lead to the temptation of manipulating data about it, as has already happened in the field of financial capital (Here it is appropriate to recall the examples of the firms Enron and Marconi).
The IC category is a generally recognized term for intangible and intangible assets involved in creating a company's value together with other assets by transforming them into other intangible resources, or into tangible resources in order to maximize the company's current value from the point of view of owners and stakeholders. It is the use of such assets in the process of value creation that transforms intangible and intangible assets into capital. This, during its circulation, leads to the creation of additional value in a company through the creation of value for owners and stakeholders.
The above features bring the task of managing IC to the fore in the company's management system. However, in order to manage intellectual capital, it is necessary to solve a few fundamental problems, which include the following: • Building a system for measuring IC and its elements in a company, consistent with its development strategy; • Development of models of the relationship between the value of the IC and its elements and the performance of the company (in this case, it is necessary to consider the correlation between individual elements within the IC); • Development of a system of factors and drivers (levers), impact on the value of IC; • Development of specific mechanisms and technologies for managing the level of IC and its elements in the company; • Development of IC management policies and programs, consistent with the company's development strategy, representing the basic rules and principles, as well as coordinated activities such as research and development, linked in place, time and resources, which should lead to the achievement of certain goals in the company's activities and development; • Integration of the developed management policy and programs into the company's management system, control of the implemented measures in the field of IC management; • Development of effective and adequate methods of ensuring communication with stakeholders regarding the disclosure of the results and intentions of the company's management in terms of management and development of IC.
From the problems listed above, it becomes clear that IC management in a company should be purposeful and systematic, i.e., represent regular management. At the same time, as practice shows, there is still a deep chasm between the recognition of intellectual capital as the most important category and object of management in modern company management and the development of specific methods, technologies, policies and management programs. In [29], the author compares the IC of a company with the underwater part of an iceberg. In addition, unfortunately, we have not yet fully explored this underwater part.
The current structure of intellectual capital usually includes three main elements: human capital (HC), structural capital (SC) and relational capital (RC).
There are other types of classification of IC elements, which in one direction or another expand the classification of IC. At the same time, if we compare the structure of the IC and the formal model of the value chain, it will become obvious that these structures are not fully correlated with each other. So, for example, human capital, as one of the most important elements of IC, is barely reflected in the value chain; moreover, value creation networks, as more complete models of the process of creating value in a company in their modern known form, do not contain value creation cycles for personnel of a company. We understand that personnel (employees)are one of the most important stakeholders, are suppliers of resources such as labor, which is one of the most fundamental factors for a company's existence and its ability to create added value; finally, personnel are a bearer of knowledge and skills, an element of intellectual capital. Thus, using the example of human capital, we see that to evaluate it will obviously require a rather complex system of indicators that should evaluate it from various angles.
At the same time, within the framework of the approaches available, other stakeholders, such as suppliers, government authorities and public organizations, are included in the value chains or networks, and then it becomes necessary to use a value creation network, based on which a network of costs for the production of a specific type of value can be formed. The network or value chain provides insight into how elements of intellectual capital are incorporated. Thus, it becomes possible to evaluate IC [11].
It is important to note that the purpose of a company's activities in relation to stakeholders is to create value, in relation to owners to ensure the growth of shareholder value is not lower than the required level and in relation to itself to ensure a safe state of operation, in which the growth in value plays a leading role. In this regard, quite extensive research is currently aimed at studying the impact of intellectual capital, as well as its components, on the value of companies [26,27,30].
In these studies, it is possible to find a stable positive multiplicative relationship between the elements of IC and the performance of companies. However, this result often depends on the chosen IC assessment model, the considered markets and regions in which the companies operate as well as their industry affiliation [31]. In addition, econometric studies have not yet fully answered the question of how investment in IC elements and returns are related. Often, in order to make a decision, we need to be confident that the returns must be increasing in nature, but there is not enough research on this yet.

Methods for Assessing the IC of Enterprises
Currently, several approaches have been formed to assess the level of a company's intellectual capital. The systematization of methods for assessing a company's IC is presented in the works of D. Luiti, M. Williams, M. Ruus [11,32,33]. Currently, there are five groups of methods for assessing IC at the micro level:  [11].
The application of most methods requires the use of accounting, financial statements, as well as confidential information about the company's activities. In addition, some methods require different market metrics to be used to determine risk-free rates, industry average beta, industry average profitability levels, etc., which vary greatly by market type and current economic environment.
Currently, another method for assessing the company's intellectual capital has been developed, which consists in conducting content analysis of the company's annual or integrated reports. The same category includes methods for analyzing information from external sources-company websites, speeches of officials and top managers, analysis of the number of shares, etc.

VAIC Intellectual Capital Assessment Method
The Value Added Intellectual Coefficient (VAIC™) method is the most common method for assessing and measuring IC, which is widely used by many scientists and practitioners in IC research [48][49][50].
In [11,51,52], the following advantages of the VAIC™ method for assessing IC are noted, namely: 1. VAIC is simple and straightforward for measuring IC value.

2.
The VAIC method is distinguished by the presence of detailed links between the company's operations, the resources used and the financial result. 3.
The calculation of the VAIC™ indicator can be performed based on the information of the corporate financial report; in addition, it does not require the use of specific market indicators and significant transformations of indicators.

4.
The VAIC™ method is more objective than other assessment methods because the data and results used are easy to verify. 5.
VAIC™ allows cross-comparison because other measurement methods require both financial and non-financial estimates, which can sometimes be subjective. 6.
The VAIC™ method can be used to measure IC and organize activities in all types of industries.
These features have led to a widespread use of the VAIC method for measuring and evaluating IC. Using this method, the influence of IC on the value, sustainable growth, and the cost of equity capital of companies in various industries is studied [53][54][55][56][57][58][59][60].
The idea of the method is that, according to the author, the creation of benefit in a company is determined by two components: physical capital and IC [39]. Therefore, the efficiency of benefit creation will be determined by the efficiency of the use of physical (or involved) capital (CEE) and the efficiency of IC (ICE). ICE itself is composed of Human Capital Efficiency (HCE) and Structural Capital Efficiency (SCE). ICE is the simple sum of these three efficiencies.
At the same time, despite its widespread use, some authors point out that it is not always possible to find a relationship between IC indicators and the market value of a company [30,61].
In addition, the disadvantages of VAIC include the fact that it does not consider the traditional third component of IC-relational capital. Many researchers believe that the missing relational capital component in VAIC is the reason for the inconsistency of IC research results using this VAIC method [62].
The development of the VAIC methodology is currently a modified MVAIC model, in which the coefficient of efficiency of using relational capital RCE is added [51,63]. According to the MVAIC model, ICE will have three components: HCE, SCE and RCE. At the same time, the use of the MVAIC model requires the involvement of additional information about the company's activities, which is not always adequately reflected in the financial statements; therefore, the MVAIC model is much less common than the VAIC. In this study, we also used the VAIC model.

Method for Assessing Intellectual Capital Using the CIV Indicator
Calculated Intangible Value (CIV) is a scheme developed by Thomas Stewart in 1997 to help investors and company management assess the value of knowledge-intensive companies and increase interest in intellectual capital [64]. This calculation method assumes that investments in physical assets can bring only the average industry income, and everything that the company receives in excess of it is due to the competent use of its intangible assets. An increase in the CIV indicator over time indicates a company's ability to generate income in the future, and vice versa, a decrease in the indicator indicates that investments in intangible assets or structural changes in the company do not pay off [65]. Among the advantages of this method, researchers note the simplicity of calculations and the availability of data, which can be obtained directly from the annual reports of public companies on official websites. In addition, the indicator is suitable for both intra-industry and inter-industry comparisons [66].
The disadvantages of this method include the following [66]: First, within the framework of this method, intangible assets are not disaggregated and not separated; for example, it does not separate the physical and financial assets of the company.
Secondly, the method is based on the return on assets indicator, which can be overestimated, underestimated or negative for some companies.
Third, the key idea of the method is that only companies with a profitability higher than the industry average have intellectual capital, but in some, especially knowledge-intensive, industries, even medium-sized companies have intellectual capital, so estimates can be significantly biased.
The method, in addition to the company's financial statements, requires the use of specific market and economic indicators, which complicates the calculations.
To overcome these shortcomings, in [66], a modified model for assessing IC based on the return on net assets is proposed. In this model, the part of the cost that exceeds the industry average return on the company's net assets and is capitalized over an infinite time interval at the weighted average rate of capital costs, which acts as an assessment of the IC.

Method for Assessing Intellectual Capital Using Content Analysis of Annual Reports
Expanding the range of approaches and methods used to analyze IC companies is important. This makes it possible to expand both the initial empirical base for assessment and to present a broader system of working with intellectual capital in a company for stakeholders.
One of the promising methods for changing the intellectual capital of companies is a method based on content analysis of annual reports and integrated reporting of companies [67][68][69]. This approach differs from the well-known approaches based on financial information because there is no unified methodology for presenting and disclosing information about the intellectual capital of companies and its elements in the annual reports and integrated reports of companies. In modern reports, there is no corresponding section dedicated to the management of intellectual capital. At the same time, it is obvious that management understands the importance of using annual reports as a communication channel with stakeholders and uses this channel to disclose information about their company's IC.
The study of a company's IC based on content analysis of annual and integrated reports of the company is based on the measurement of IC elements and its value as a whole based on the frequency of disclosure of certain components in the texts of the above documents.
From a methodological point of view, the types of content analysis that are currently used to study various socio-economic aspects are divided into two approaches depending on the methods for registering counting units.
The first approach is based on calculating the facts of disclosure of certain accounting units. When a unit is found in the text, the search stops. In this case, the information disclosure indices act as a quantitative assessment, as the ratio of disclosed counting units to the total number of counting units that are searched for in the text [70][71][72][73][74]. In this approach, information items are only used once. At the same time, this approach, called the "virginity principle" or "appearance approach" of counting information, does not allow us to assess the importance of a counting unit that is conveyed in the analyzed document.
The second approach is based on counting the number of mentions of certain accounting units. Many researchers point out that the amount of disclosure is important, as it shows the importance of a category [75][76][77][78]. In the opinion of these researchers, volumetric analysis is a completely acceptable research method, which allows you to reveal the importance of information.
In addition, in content analysis, approaches are distinguished based on the calculation of various transcoding units. These can be words, sentences or paragraphs. Obviously, the category of text, as a single element, cannot be used in the content analysis of annual and integrated reports due to the wide variety of topics covered, as well as its rather large volume. Regarding the use of different recoding units, each of the approaches has its own advantages and disadvantages [68,75]. Thus, the use of words (or phrases) as a transcoding unit does not always allow us to accurately determine whether it belongs to a particular category. On the other hand, the use of sentences or paragraphs requires considering the multiple forms of content, and, as a result, the use of special analytical procedures that would allow for separating these topics. This, in turn, can also lead to certain errors when calculating in an automatic way. In any case, the choice of the transcoding unit remains with the researcher, the fundamental point is that all the basic rules, conditions for transcoding, as well as dictionaries or categories and subcategories of transcoding are strictly disclosed in the study. All this will allow us in the future to increase the comparability and reliability of the results obtained, as well as to choose the most adequate options for the content analysis method.
It is believed that reflecting information about IC in annual reports, as well as in integrated reports, will help with the management and control of company knowledge, as it shows stakeholders how and with what efforts a company develops its intellectual capital [79,80]. Placing information about IC in the annual reports of companies is one of the key channels of voluntary disclosure for stakeholders [81][82][83]. However, in the total number of studies, the use of the content analysis method of annual reports for IC research is much less common than research using other methods, for example, methods based on the analysis of the financial statements of companies.
Several studies have found results showing that content analysis in annual reports is dominated by information from relational capital (RC), reflecting the prevailing value for shareholders [69,70,75,82,[84][85][86]. Comparable RC disclosures in research are evident, showing that companies around the world agree that RC information is strategically more important than HC and SC. Some prominent IC categories that may reflect the importance of adding value to companies are information about customers, employees, community, director skills, distribution channels and business partners [87].
Using content analysis, quantitative estimates of the intellectual capital ICR and its structural elements-human capital resources (HCR), structural capital resources (SCR) and relational capital resources (RCR)-were obtained.

Intellectual Capital of Trading Companies
The trade sector in the Russian Federation belongs to a group of traditional sectors of the economy with a relatively low level of intangible assets and innovations. Currently, its share of national trading activity in GDP is 16.7%, the average annual number of employees is 18.5%, investments in fixed assets are 4.3% and the share of tax payments is 11.1%. The modern trade sector in Russia is one of the most stable sectors of its national economy. Comparative analysis of GDP growth rates and retail trade turnover over the past ten years allows us to conclude that the trade industry as a whole is characterized by relatively higher growth rates compared to GDP [88]. Moreover, trade is characterized by high levels of growth in gross added value compared to other sectors of the economy.
Retail trade is one of the branches of the economy that is highly dependent on knowledge [89]. Because retail trade is an element of the commodity-producing system, it does not create a product itself; therefore, there are practically no product innovations in retail trade. At the same time, such factors of success in retail trade as simplicity, level of personnel costs, overhead costs, supply chains, costs and online channels come to the fore [90].
These key success factors rely heavily on a good knowledge management system, human capital and customer relationships that are part of the IC components to help retailers effectively manage their assets and knowledge to achieve these factors. For this reason, IC is also important for retail businesses.
Another important aspect of the activities of modern companies is the expansion of external communication channels with stakeholders. One of these channels is a company's annual reports, where management presents the results and future vision of its strategy. Since IC has a strategic importance in a company's activities, considerable attention is paid in the annual reports to the disclosure of information on the results and prospects of managing IC for trading companies.
However, studies that would include a comprehensive analysis of IC trading companies based on financial and non-financial information are rare. As a rule, IC research is carried out based on financial Sustainability 2020, 12, 7095 9 of 21 statements [52,91], or based on non-financial information, for example, analysis of annual or integrated reports [67,70,87].

Key Research Hypotheses
The purpose of this study is to quantify the value of the intellectual capital of a trading company, as well as its components, and to identify the influence of the size and structure of intellectual capital on the results of a company's business. Calculations were performed using alternative methods for assessing IC.
The research method is a combined one, which includes the use of three different measurement methods for assessing IC: VAIC, CIV and content analysis (CA).
The empirical base of the study is the financial and annual statements of a company operating in the retail sector in the Russian Federation, as well as information from the state statistics bodies of the Russian Federation and from the ratings and analytical agency Bloomberg.
Research hypothesis: it was assumed that there are positive relationships between the amount of a company's intellectual capital used and the efficiency of its financial activities, the company's value as well as the level of information disclosure about IC in the company's annual reports.
Several hypotheses were considered in the work. The general scheme of the research hypotheses proposed in the work is shown in Figure 1. All hypotheses were divided into 5 groups.

The first group of hypotheses consisted of assessing the impact of intellectual capital and its components, calculated using the VAIC and CA models, on the return on assets.

Hypothesis 1 (H1). IC and its components have a significant positive impact on the return on assets.
Hypothesis H1 included four particular hypotheses: 1 (H1.1). The elements of intellectual capital calculated using the VAIC model have a significant positive impact on the return on assets. Hypothesis 1.3 (H1.3). The structural elements of intellectual capital HCR, SCR and RCR, calculated using CA, have a significant positive impact on the return on assets .   Hypothesis 1.4 (H1.4).

Additionally, the study formulated hypotheses designed to test the presence of a relationship between the structural elements of IC, determined by VAIC and CA methods, as well as between the indicators of intellectual capital, which were assessed using the VAIC, CIV and CA methods. These hypotheses were formulated in order to determine the presence of a relationship between the involved IC value and the level of its disclosure.
Hypothesis H5 included three particular hypotheses: H5.1). The level of disclosure of human capital in annual reports reflects the level of human capital involvement in creating benefit.

Hypothesis 5.2 (H5.2).
The level of disclosure of structural capital in the annual reports reflects the level of involvement of structural capital in the creation of benefit.

Initial Data
The research used the annual and financial statements of a trading company operating on the Russian market as the initial data. Since historically the creation of companies in the form of joint stock companies, which obligatory submit annual reports, began not so long ago, systematic data for 7 years were available. In addition, we were able to calculate the CIV index for the previous 9 years.

Dependent Variables
Guided by various works [49,51,54], return on assets (ROA) and return on equity (ROE) are usually used to measure financial results.
ROA measures the efficiency of companies in using total assets and is calculated by dividing net income by average total assets. ROE is the return to shareholders of ordinary shares and is calculated by dividing net income by the average share capital.
The CIV is the discounted weighted average cost of capital amount of the future residual operating income generated by the intangible assets of a company over an infinite period. In this context, CIV is an assessment of the IC generated by a company because of strategic development.
The method for calculating the CIV indicator includes the following steps: 1.
For a series of data over several years, smoothing is performed (with a moving average of over 3 years); 2.
The pre-tax income of the company (Earnings Before Interest and Taxes, EBIT) (smoothed data) is calculated; 3.
The moving average of tangible assets TA is calculated; 4.
The moving average of intangible assets IA is calculated; 5.
The return on assets of the company is calculated; 6.
The industry average return on assets is calculated; 7.
Excess income is calculated as the difference between the pre-tax income of the enterprise and the income of the assets of the enterprise, calculated according to the average industry profitability (6). The formula only works if the company's return on assets is higher than the industry average return on assets.
If ROA comp > ROA ind , then the CIV is calculated as: In the case of an infinite period of capitalization of intellectual capital, it is simplified to the following form: where: WACC-weighted average rate of company capital costs; t-income tax rate; A-depreciation. Economic value added (EVA) is the amount of profit that remains at the disposal of the company for the reporting period, taking into account all economic and opportunity costs of capital employed. Traditionally EVA is an indicator of the growth of the company's value. In this work, EVA was calculated using the expression: where: HCEshows how effectively human capital is used (equal to the ratio of value added and labor costs); SCE shows how effectively organizational capital is used (equal to the ratio of value added minus human capital and value added); CEE shows how effectively used capital is used. The individual components of the VAIC were calculated as follows: where: VA-value added; HC-human capital, measured by the wages of all workers.
where: SC-structural capital measured by the difference between VA and HC.
where: CE-the capital employed book value of net tangible assets of the company. The value added in expressions (9)-(11) was calculated using the following expression: where: C-company employee salary; D-depreciation; A-depreciation; OP-operating profit. 2. Assessments of IC and its components were carried out using content analysis. The content analysis of the annual reports was carried out by counting the number of words and phrases used in relation to three subcategories of intellectual capital-human capital HCR, structural capital SCR and relational capital RCR. As an indicator reflecting the level of disclosure of IC and its components, the number of mentions of words and phrases revealing subcategories of intellectual capital was considered in total for human capital-22 subcategories, for structural capital-18 subcategories, for relational capital-21 subcategories. The composition of the subcategories was taken from [70]. For each mention of a word or phrase, 1 point was assigned. The number of points was presented as the disclosure rating.

Empirical Results
Before proceeding to the description of the results of the constructed models and testing of hypotheses, let us consider the results of the assessment of the IC, performed by various methods.
On Figure 2, the results of the IR calculation by the VAIC method are presented. Figure 3 shows the results of calculating the IC by using the CIV method. In Figure 4, the results of calculating the IC by the content analysis method are presented. From the presented results, it can be seen that the VAIC and CA methods reflect the ratio of the IC elements in different ways. According to the VAIC, most of the IC is formed at the expense of the human capital efficiency indicator HCE, which gives about 75% of the contribution to VAIC. For the CA model, a different picture is observed. Here, HCR human capital takes the smallest position for IC elements, and structural and relational capitals take the largest position. The use of content analysis in [5] showed that relational capital takes a significant position, then human capital and structural capital. According to the authors, the significant role of relational capital in annual reports is because a company uses this to demonstrate to investors its attitude towards various groups of stakeholders.
capital was considered in total for human capital-22 subcategories, for structural capital-18 subcategories, for relational capital-21 subcategories. The composition of the subcategories was taken from [70]. For each mention of a word or phrase, 1 point was assigned. The number of points was presented as the disclosure rating.

Empirical Results
Before proceeding to the description of the results of the constructed models and testing of hypotheses, let us consider the results of the assessment of the IC, performed by various methods.
On Figure 2, the results of the IR calculation by the VAIC method are presented.    In Figure 4, the results of calculating the IC by the content analysis method are presented. From the presented results, it can be seen that the VAIC and CA methods reflect the ratio of the IC elements in different ways. According to the VAIC, most of the IC is formed at the expense of the human capital efficiency indicator HCE, which gives about 75% of the contribution to VAIC. For the CA model, a different picture is observed. Here, HCR human capital takes the smallest position for IC elements, and structural and relational capitals take the largest position. The use of content analysis in [5] showed that relational capital takes a significant position, then human capital  Table 1, the average VAIC value is 2.908, which means that the trading company managed to create an added value of 2.908 rubles for every 1 ruble invested in the company. The descriptive statistics also show that HCE is the most influential component in creating added value for retailers, with an average of 2.2 rubles. In addition, this study also yields a result that is consistent with the proposed theory in the IC literature, which states that IC or intangible assets create greater added value for companies compared to tangible assets, which can be shown by the average CEE score (0.196) [49,51]. The contribution of the individual components is almost the same as the contribution of the individual elements of IC and physical capital in a study of retailers in Indonesia. The results of the analysis of the obtained models are presented in Table 2. It presents the results of analysis of variance of models, as well as analysis based on criterion and linearity. The analysis of the results presented in the table allowed us to conclude that from all the hypotheses of the study, the hypothesis of the relationship between VAIC and return on assets was statistically confirmed. This model is: In addition, for the hypothesis of the third group, the presence of a statistical relationship between the indicator CIV and the structural capital, determined both by the VAIC model and by means of content analysis, was obtained: the form of these models is presented below: Models for the hypotheses of the fourth group were not confirmed. Among the models of group 5, a model was confirmed that reflects the relationship between the use of human capital in creating benefit and the level of disclosure of human capital in annual reports. Model view: HCR = −104.55 − 157.88 × HCE.

The Discussion of the Results
Based on the results presented above, we will give a brief description of the presented results. The first conclusion that can be drawn is the influence of IC on the profitability (profitability) of a trading company. A statistically significant relationship was found between return on assets and VAIC (model H1.2). This result agrees with the results obtained in [49,51]. At the same time, no statistically significant relationship was found for individual VAIC components, which may indicate the instability of the impact of human and structural capital on a company's profitability. Thus, we can conclude that investment in intellectual capital can lead to an increase in the return on assets. The growth in return on assets per VAIC point is 0.026, i.e., about 2.6%, which is a high figure.
It should be noted that a sufficiently high relationship level was also found for the return on assets and elements of intellectual capital, which are reflected in the annual reports (a high R2 was obtained). In our opinion, this indicates that, overall, the company's management adequately assesses the level of development and the effectiveness of the return on the elements of IC, although this is not statistically significant in nature.
The study of the relationship between the return on equity and IC elements, calculated both by the VAIC model and reflected in the reports, did not reveal a statistically significant relationship. Perhaps this is due to the fact that during the period under review, the company under study carried out a fairly intensive market expansion, which led to sharp fluctuations in the capital structure and, as a consequence, to significant fluctuations in the return on equity. Perhaps, observation on a wider sample and a wider time interval will provide more significant results on the return on equity.
Interesting results were obtained for the third group of hypotheses. A stable statistical relationship was revealed between the coefficient of intellectual value CIV and the value of structural capital. Moreover, this relationship is an inverse one, i.e., an increase in structural capital (SCE and SCR) leads to a decrease in CIV, i.e., to its destruction of the company's intellectual value. At the same time, human capital (HCE and HCR) in the H3.1 and H3.3 models and the RCR relational capital in the H3.3 model have a more significant positive impact on CIV. This influence of structural capital on the formation of the company's intellectual value may be due to the fact that currently, institutional investors and asset managers are focused on obtaining short-term profits (faster earnings per share), rather than long-term profits. It also shows that they place more emphasis on innovation and growth than on investment. This result is to some extent consistent with the results obtained in [52], where a statistically significant inverse relationship between structural capital and company value was also revealed.
The study of the influence of the IC and its elements on the market value did not reveal any connection between them. This result is consistent with research [91][92][93]. The reasons for this result may be due, on the one hand, to the closeness of data on IC, which is confirmed by the results of this study (the absence of relationships in the hypotheses of the fifth group). On the other hand, market value is highly influenced by market sentiment and external factors such as risk aversion by investors that make them ignore a company's financial reality, even if it has improved its financial results.
The study of the hypotheses of the fifth group allows us to make a stable conclusion that the degree of reflection of IC and its elements in annual reports is in no way connected with the use of IC in creating profit and value for a company. This means that the researched company does not have a systematic IC management policy, one of the aspects of which is the disclosure and communication of information about the IC to stakeholders.

Conclusions
For companies in the modern economy, IC is one of the most important drivers of profit and value creation based on sustainable, hard-to-copy competitive advantages.
The presented study confirms the hypothesis about the influence of IC, considered in the form of the VAIC model, on the profitability of a trading company operating in the Russian market. Also, statistically significant relationships were found between the company's structural capital and the intellectual capital ratio according to the CIV model.
In this study, it was found that IC and its elements do not affect the value of the company. Therefore, for investors, IR is not yet a fundamental indicator which they could use to make the right investment decisions.
The second important conclusion that this study allowed us to make is that at present, even successfully developing companies in the process of their functioning and development do not pay enough attention to adequate reflection of the results of using IC. On the one hand, this is due to the youthfulness of the IC concept, and on the other hand is due to the lack of generally accepted methods and technologies for adequate disclosure of information about IC in the annual reporting of companies.
The peculiarity of this is that the trading industry belongs to the group of traditional industries for which the share of intellectual capital and intangible assets is not the leading one, despite the fact that with the development of networkization and digitalization, the share of intellectual assets is steadily increasing across the board.
The presented study has several limitations. The object of the study was a trading company, whose shares are listed on the stock exchange, and which systematically submitted ready-made reports. Finding empirical material that allows conducting similar studies for Russian trading companies seems to be rather difficult. However, studies of trading companies in other emerging economies may be of interest.
It is necessary to consider a wider range of industries for which innovation and intangible assets play a more important role, for example, telecommunications companies, companies operating in the information and consulting industries, banking and finance. However, the problem lies in the fact that the market of the Russian Federation has existed for a fairly short time, belongs to the group of emerging markets and only quite recently began to move to generally accepted forms and technologies of corporate governance. The lives of most successful companies do not exceed 10-15 years, and they submit annual reports only for the last 5-10 years. At the same time, when studying intellectual capital based on annual reports, as a rule, rather long observation intervals are considered, often spanning 15-20 years.
It should also be noted that most IC studies use the VAIC model as a base model, while the results of IC studies using the CIV model and its modifications, as well as studies based on the analysis of annual and integrated reporting, are still quite rare.
The research results show the ways to improve the quality of presentation of information about the intellectual capital involved in the creation of financial results and company value.
From the point of view of further research, it is of considerable interest to study the industry specifics in the use of IC and its presentation in annual reports. It is possible that for companies in knowledge-based industries and traditional companies that rely mainly on physical assets to create profit and value, the results of IC research will be completely different.
