        <p>This paper investigates the impact of intangible assets on the financial performance of Slovak ICT companies in the context of the knowledge economy. The paper uses a panel data regression analysis to test the hypothesis that intangible assets have a significant positive efect on four indicators of financial performance: Return on Assets, Net Profit Margin, Assets Turnover, and Return on Equity. The paper analyzes a sample of 180 Slovak ICT companies for the period 2015-2019, using eight independent variables: Research and Development Intensity, Research and Development Intensity Squared, Software, Intellectual Property Rights, Acquired Intangible Assets, Leverage, Size, and Dummy variable for ICT sub-sectors. The paper applies various tests to select the appropriate estimation method and to check the adequacy of each model. The results partially confirm the hypothesis, as only Research and Development Intensity, Research and Development Intensity Squared, and Acquired Intangible Assets have a significant positive impact on some indicators of financial performance. The paper also finds that the influence of intangible assets varies depending on the type and measure of financial performance. The paper contributes to the literature on intangible assets and financial performance by providing empirical evidence from Slovak ICT companies. The paper also provides some implications for managers and policymakers to improve their intangible investment policy.</p>

      <title>1. Introduction</title>
      <p>
        Over the past few decades, extensive discourse among researchers has centered on the evolving
role of various types of capital in shaping the economic value and sustainability of enterprises,
paving the way for their enduring success. Particularly noteworthy is the recognition of
intellectual capital’s pivotal role in this metamorphosis, influenced by shifts in production focus
and management strategies. This shift is marked by a transition from the conventional emphasis
on physical capital and labor to a spotlight on intellectual capital and the exchange of ideas,
buoyed by intellectual property rights, particularly patents for their integration with technology
[
        <xref ref-type="bibr" rid="ref2 ref3 ref4 ref5">2, 3, 4, 5</xref>
        ]. In this transformative landscape, the valuation and profitability of enterprises are
increasingly tethered to their adeptness in harnessing their innovative potential and capitalizing
on their intangible assets. Against the backdrop of overcoming the COVID-19 pandemic’s
repercussions [
        <xref ref-type="bibr" rid="ref6 ref7">6, 7</xref>
        ] and the global implementation of proactive sanctions strategies, which
have led to reduced trade in conventional goods and services, the role of unique intellectual
technologies in anchoring stable enterprise value gains prominence.
      </p>
      <p>This new paradigm necessitates a growing reliance on national intellectual capital to fortify
the economies of developed nations. Moreover, for numerous enterprises, financial performance
hinges on the judicious crafting of policies that foster both the creation of novel intangible
assets and the eficient utilization of existing ones. This involves their seamless integration into
enterprise operations, fostering efective partnerships, governance, and control. In this context,
enterprises frequently encounter network efects and an elevated exposure to market and
technological risks. Consequently, a recalibration of business strategies becomes imperative,
encompassing initiatives that leverage intangible assets to their strategic advantage. This
is especially pertinent for high-tech entities, characterized by their substantial reliance on
intangible assets to develop innovative technological products and services.</p>
      <p>
        In light of these economic transformations, the quest for fresh theories and strategies is
imperative to underpin informed decisions and management conduct in enterprises rich in
intangible assets. A pertinent avenue of investigation is the impact of intangible assets on
companies’ financial performance, specifically focusing on the context of Slovak enterprises
operating in the information and communications technology (ICT) sector. These companies,
encompassing those engaged in information processing, storage, transfer, production of
computing and telecommunication devices, and related services, epitomize high-tech enterprises.
Their value creation processes are intrinsically linked to the eficient utilization of intangible
assets. Investments in high-tech intangible assets within the ICT sector hold the promise of
enhancing their financial metrics. However, as Huňady et al. [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] have indicated, Slovakia still
exhibits a limited presence of business Research and Development (R&amp;D) in the ICT sector. This
suggests a cautious approach to intangible investments among Slovak ICT companies, possibly
due to perceived risks and uncertainties surrounding their potential returns. Consequently, to
mitigate such risks and uncertainties and to formulate an efective intangible investment policy,
it becomes paramount to ascertain the intricate relationships between diverse intangible asset
categories and various financial performance metrics.
      </p>
      <p>
        Over the last decade, the Slovak Republic has witnessed vigorous development in its ICT
sector. The number of individuals employed in the information and communication technology
services sector surged from 28,905 in 2009 to 53,676 in 2019 [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ], underscoring a near doubling of
the workforce over the span of a decade. Reflecting this expansion, the ICT sector’s contribution
to the country’s Gross Domestic Product (GDP) reached 4.2%, exerting significant influence on
related industries as well. Endowed with numerous advantages, including high adaptability
to enterprise activities, elevated value addition, well-established educational infrastructure,
robust institutional networks, diversification in the telecommunications segment, strategic
geographical positioning, extensive data and network coverage, and attractive investment
incentives, the ICT sector garners substantial investor interest [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. The Slovak government’s
active support for the sector, as evidenced by the provision of incentives such as tax reliefs,
cash grants, job creation contributions, discounted real estate transactions, and a favorable
R&amp;D tax regime, further amplifies its allure [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Hence, examining the impact of intangible
assets on the financial performance of Slovak ICT firms, within this conducive environment,
assumes particular significance. Such an investigation can illuminate avenues for developing
and fine-tuning intangible investment policies to enhance the financial performance of these
companies.
      </p>
      <p>Given the pivotal role of intangible assets in shaping the eficiency of high-tech enterprises,
a research hypothesis has been formulated. This study hypothesizes a significant positive
correlation between intangible assets and the financial performance of ICT companies. Recognizing
that the strength of this influence may also vary based on company size, levels of borrowed
capital, and sub-sector categorization within the ICT industry, the analysis of the impact of
intangible assets on financial performance takes into account these factors. The resulting
insights are expected to inform recommendations for Slovak ICT companies’ intangible asset
investment decisions.</p>

      <title>2. Theoretical background</title>
      <p>
        Problems of influence of intangible assets in their broad (economic) understanding on financial
performance of high-tech companies are paid considerable attention of academicians. First
of all, this is conditioned by the decisive role of intellectual capital for such enterprises in the
context of the development of knowledge economy, which is based on ideas, R&amp;D, innovations
and technological progress. Scientists analyze of the impact of diferent intangible values on
ifnancial performance: intangible assets (the concept of IAS 38 [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ]), intellectual capital (as
a combination of human, organizational, and client capital), or separate components of two
data. These studies cover diferent types of enterprises from diferent countries of the world,
which represent diferent sectors of the economy. Since intellectual capital includes, to the most
extent, all intangible assets that are the result of human intellectual activity, this article also
analyzes the impact of intellectual capital and its components on the financial performance
of ICT companies. In addition, a number of researchers are conducting studies of the impact
of intangible assets both on individual components of financial performance, in particular, on
profitability, and on broader categories, in particular, on total performance of the company or
companies value.
      </p>
      <p>Table 1 lists the number of articles and their quotations, which reveal the relationship between
“Intangible assets” / “Intellectual capital” and “Financial performance” in science-based databases
of Scopus, Web of Science and Google Scholar.</p>
      <p>The results of analysis of scientific databases are obtained (table 1) testify to the existence of
a considerable number of publications in this direction of researches, as well as their influence
on scientific works of other authors, which is confirmed by a considerable number of references
to data of other authors and their constant growth from year to year. The cluster analysis of
the key words of the articles from the databases of the Scopus and Web of Science on the basis
of the use of VOSviewer allowed to confirm this conclusion. There was also a large number of
publications that examined the impact of structural elements of intangible assets or intellectual
capital (research and development, intangible resources, customer capital, structural capital,
human capital, social capital, relational capital) on financial performance (figure 1). In addition,
publications have been identified that investigate the impact of intangible assets or intellectual
capital on other types of indicators that characterize the performance of the enterprise – firm
performance, business performance, corporate performance, firm value, efectiveness, eficiency,
profitability, ROA, competitive advantage etc. (figure 2).</p>
      <p>
        Little attention is paid directly to the issue of impact of intangible values on financial
performance of ICT companies, although the presence of significant positive relationships between
with two variables is confirmed in the vast majority of results. Gan and Saleh [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] studied the
connection between intellectual capital components of corporate performance among high-tech
companies listed on Bursa Malaysia, in particular, profitability, and productivity. Based on the
use of regression analysis, it was found that companies with larger intellectual capital as a rule
have better profitability (ROA) and more eficient productivity (ATO).

      <p>
        Li and Wang [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ] investigated the impact of diferent intangible assets (R&amp;D expenditure,
employee benefit, sales training) on profitability indicators (ROA) of Hong Kong Listed IT
companies using regression analysis. They found a positive relationship between intangible
assets and ROA.

      <p>
        Dženopoljac et al. [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ] examined the role of intellectual capital and its key components in
provision for financial performance (ROA, ROE, ROIC, ATO) of Serbian ICT sector companies
during 2009–2013. They used Value-added intellectual coeficient (VAIC) as a measure of the
IC contribution to value creation. The results obtained by the authors revealed that only one
component of VAIC – CEE (capital-employed eficiency) had a significant impact on financial
performance indicators, except for the indicator ROIC. Khan [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ] also used VAIC as firms
intangibility measure when analyzed the impact of intellectual capital on the financial performance of
the 51 Indian IT companies for the period 2006–2016. He found a significant positive association
of VAIC with profitability, and an insignificant relationship with productivity, and significant
positive association of CEE with profitability and productivity of Indian IT companies.

        Zhang [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ] analysed the relationship between degree of intangible assets and profitability
for 17 Chinese listed telecommunication firms’ for the period from 2014 to 2016. He found
a positive and significant efect of Intangible assets ratio on ROA. Also, he emphasized the
possibility of the inaccuracy of the obtained results due to the conservative nature of Chinese
accounting standards rules in measuring intangible assets.
      </p>
      <p>
        Huňady et al. [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] examined the role of innovations in performance of ICT sector companies
from 24 countries during the years 2008–2016. Using regression analysis for macro-level data,
they found positive efect of R&amp;D expenditure on apparent labour productivity and value added
in ICT sector.

      <p>
        Qureshi and Siddiqui [
        <xref ref-type="bibr" rid="ref16">16</xref>
        ] analyzed an efect of intangible assets on financial performance
(ROA, ROE, ROIC, ATO and NPM) of the 80 global technology firms for the period from 2015 to
2018. They confirmed a significant negative efect of intangible assets on ROE, ROIC, ATO, and
insignificant positive impact on companies’ profitability. Moreover, the force of this influence
considerably varies depending on the country’s innovative development.
      </p>
      <p>
        Lopes and Ferreira [
        <xref ref-type="bibr" rid="ref17">17</xref>
        ] also investigated the impact of intangibles on the performance
indicators of major world technological firms (Turnover, ROA, ROE, ROS, EPS), have received
evidence of existence of negative correlation between all intangible variables, control variables
(Size, Leverage) with ROA. These conclusions are also confirmed by Sundaresan et al. [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ], who
investigated the impact of intangible assets on financial performance of 38 Taiwanese listed
technology firms for the period 2015–2019. The authors also revealed the existence of a lack of
a significant relationship between intangible assets and ROA, but found significant influence
of size on ROA. At the same time, they confirmed significant impact of intangibles on ROE.
The results of the ROA received by Lopes and Ferreira [
        <xref ref-type="bibr" rid="ref17">17</xref>
        ], Sundaresan et al. [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ] are in direct
contradiction with most of the conclusions obtained by the authors who studied impact of
intangibles on performance of ICT companies.
      </p>
      <p>
        Radonić et al. [
        <xref ref-type="bibr" rid="ref19">19</xref>
        ] studied the role of intellectual capital components (human, relational,
structural and innovation capital) in ensuring the achievement of financial performance
indicators (ROA, ROE, Net Profit, etc.) of South-East Europe IT industry companies. In their
study, as a theoretical background they used a resource-based view on intellectual capital,
which involves analyzing the impact of its individual components on financial performance
indicators. In particular, the authors established that innovation capital has the strongest impact
and human capital has an indirect impact on the financial performance of IT companies. A
similar resource-based approach was also used by Serpeninova et al. [
        <xref ref-type="bibr" rid="ref20">20</xref>
        ], who as a result of a
study of the impact of intellectual capital on the profitability of Slovak software development
companies (ROA, NPM, GPM, EBITM) found an absence of a significant relationship between
them. The authors considered the main reason for this to be the imperfection of the current
accounting standards, for instance, IAS 38, in terms of criteria for recognizing and evaluating
the intellectual capital of enterprises.
      </p>
      <p>The analysis of studies on the issues of the research made it possible to establish the existence
of mutually contradictory evidence regarding the impact of intangible assets on the financial
performance. In general, this does not allow the management of enterprises to efectively
control intangible values aimed at creating internal value, and for investors – to receive clear
signals for making efective investments. Considering the above, the following objectives were
formulated: to measure the relationship between intangible assets and the financial performance
of Slovak ICT companies; to investigate which components of intangible assets have the most
significant or insignificant impact on the financial performance of Slovak ICT companies; to
form recommendations for improving the investment policy of ICT companies, based on the
level of significance of the elements of intangible assets from the point of view of increasing
ifnancial results.</p>

from financial statements of such enterprises, available in the open access, as well as the
information from database “FinStat” was used to form panel data. Only those companies, for
which the necessary information for the 5-year period was available, were included in the

switching equipment, transmission equipment, customer premises equipment), measuring, medical,
navigation, radio, optical and other electronic equipment, as well as production of various
types of accessories for such products (electrical boards, magnetic and optical media, etc.). In
order to take into account the influence sub-sectors afiliation on financial performance of ICT

        <title>3.2. Variables</title>
        <p>
          In the research for characteristics of financial performance of ICT companies were used four
dependent variables – Return on Assets, Net Profit Margin, Return on Equity, Assets Turnover,
and used in their work by researchers for simiral empirical analysis of the relationship between
intangibles values and company financial performance [
          <xref ref-type="bibr" rid="ref11 ref13 ref16 ref18 ref19 ref20">11, 13, 16, 18, 19, 20</xref>
          ]. For explanation of
a relation between intangible assets and financial performance of ICT companies used intangible
assets variables – Research and Development Intensity, Research and Development Intensity
Squared, Software, Intellectual Property Rights, Acquired Intangible Assets. The election of
such independent variable is justified by the financial statements of Slovak ICT companies in the
disclosure of information about intangible assets. As it was revealed by Huňady et al. [
          <xref ref-type="bibr" rid="ref8">8</xref>
          ], the
ifrm’s ICT sector account for significant share of total business R&amp;D expenditure in economy in
most countries. Therefore, in the analysis impact of intangible assets on financial performance
of ICT sector an important role should be assigned to R&amp;D indicators. As a result, the study
does not use the indicator of R&amp;D costs but uses two calculation ratios that characterize the
R&amp;D of the companies. In addition, based on previous studies [
          <xref ref-type="bibr" rid="ref20 ref21 ref22">21, 22, 20</xref>
          ] in our study used
three control variables – Leverage, Size and Dummy variable for ICT sub-sectors. Use of these
variables will allow to control for a significant efects of company size, level of borrowing capital,
and unseen role of ICT sub-sectors afiliation.

        <p>The dynamics of four indicators, that characterize financial performance of Slovak ICT

their growth in 2016–2018 years, as well as their simultaneous decrease in 2018–2019; during
2018–2019 years only growth of ROE indicator occurs. In general, common behavior was found

        <p>The descriptive statistics (observation, mean, median, standard deviation, minimum, maximum)
of a full sample are presented in table 3.</p>
        <p>From table 3 it can be observed that the full sample is measured with 180 units. The largest
deviations in variables are related to SOFT (5,95⋅104), IPR (2,89⋅104), AIA (1,61⋅105) and ROE
(4,30). Large diferences between the minimum and the maximum values of ROA, ATO, and
ROE show that the financial performance levels of ICT companies are quite distinct. For some
variables (ATO, LEV, IPR, AIA, l_SIZE) the mean value is greater than the standard deviation
value, as a result, the data in these variables have a small distribution. ROA, NPM, and ROE
have a higher standard deviation than their mean. This indicates a relatively large set of ratios
that will characterize the normal distribution curve and will not be outliers. The closeness of
the mean (13,5) and median (13,3) values for l_SIZE indicates a high level of symmetry in the
distribution of range values, that is, the size of the studied enterprises. The mean value of the
LEV ratio is 0,438, and this means that approximately 44% of the total assets of ICT companies
are financed through borrowed resources.</p>
        <p>
          In general, correlation matrix of variables used in Models 1-4 (figure 5), testifies to absence
multicollinearity problem, since in most cases, the correlation coeficient is less than 0,5 (–0,5).
The only exception is the high correlation coeficient between variables RDI and RDI2 (0,9), which
is understandable given that RDI2 is a squared function of RDI. However, as Özkan [
          <xref ref-type="bibr" rid="ref23">23</xref>
          ] notes,
the practice of applying such mutually-correcting indicators is normal in the regression analysis
performed to check the efect of interrelated variables on financial performance indicators. In
particular, simultaneous use in regression models of variables RDI and RDI2 allows to detect
presence U-inverted relation between R&amp;D and financial performance of a company.

        <title>5.2. Selection of estimate panel data parameter</title>
        <p>The choice of estimate panel data parameter for each of the selected models plays an important
role in the regression analysis of panel data. This parameter should be adequately correlated
with the data used in the corresponding model. Proceeding from F-statistics test for Model
1 F(179; 712) = 1,17767 with p-value 0,0766456, which is more than 0,05 and confirms null
hypothesis in relation to pooled OLS model. The need for such a choice estimate parameter for
Model 1 also confirmed the application Breusch-Pagan test, according to which chi-square (1) &gt;
2,04561 p-value = 0,152645, which is larger than 0.05 and confirms zero hypotheses. The use
of F-statistics test and Breusch-Pagan test also confirmed the need for use pooled OLS model
as a quality estimate parameter for Model 2. For Model 3 after application F-statistics test it
was received F(179; 712) = 1,23387 with p-value 0,0331413, that is less than 0,05 and testifies to
the adequacy of application Fixed efects method (FEM). However, this conclusion is refuted as
a result Breusch-Pagan test, according to chi-square (1) &gt; 3,58479 p-value = 0,0583107, which
is larger than 0,05 and confirms zero hypothesis of adequacy pooled OLS model. Considering
the results Hausman test (p-value = prob(chi-square (8) &gt; 4,34179) = 0,825045), according to
which more appropriate is the application of Random efects method (REM) than FEM, for
Model 3 more appropriate also consider the application of pooled OLS model. For Model 4 after
application of F-statistics test F(179; 712) = 1,32394 of p-value 0,00693691, which is less than
0,05 and shows the adequacy of application of FEM. This is the test followed by the p-value =

        <title>5.3. Assumption test results</title>
        <p>To verify the adequacy of the Panel data for Models 1-4 that is collected about ICT companies,
it should be diagnosed using Normality test, Autocorrelation test and Heteroscedasticity test.
Normality test for all Models 1-4 allowed to detect abnormal distribution of the error. For
example, for Model 1 for chi-square (2) = 4119,75 p-value = 0, which is less than 0,05, and does
not confirm zero hypotheses about the normal distribution of balances. Review null hypothesis
about no first-order autocorrelation based on usage Wooldridge test for autocorrelation allowed
to confirm it for all four models. In particular, for all Models 1-4 p-value it is more than 0,05
(0,73367; 0,923389; 0,193049; 0,227822), confirming null hypothesis. White test was used to
check the heteroscedasticity of a models 1–3. Since the obtained p-value for each of the three
models (0,284134; 0,999935; 0,421088) is more than the critical value, the zero hypothesis about
the absence of heteroscedasticity is forgiven. For Model 4 with estimate parameter FEM was
applied non-parametric Walk test, which also was established the presence of heteroscedasticity.
In particular, chi-square(180) = 78593,1 p-value = 0 was received. Since p-value is less than 0,05,
there is an inhomogeneous observation and a diferent variance of a Model 4 random error,
which confirms the existence of heteroscodesticity.</p>
        <p>
          To solve the problem of inadequacy of all Models 1–4 used by this data due to the problem
of improper distribution of the error and heteroscedasticity, the use of robust estimators is
proposed. They help minimize or eliminate impact of outliers in a Models 1-4, improving the
results of panel data regression analysis. Practice of use robust standard errors in regression
analysis was also used in research of scientists who study the impact of intangible assets and
their components on the performance of enterprises [

          Based on the results of the regression analysis, const, RDI, RDI2, SOFT and AIA are statistically
significant (there are stars in the last column of table 4), having the highest level of significance
at the 1% level. Accordingly, these indicators have the highest impact on ROA. In addition
to RDI and AIA, other significant indicators have a direct impact on ROA and RDI and AIA
are rotating. The presence of a diferent direction of influence in RDI and RDI2 indicates the
presence of U-inverted relationship between R&amp;D and ROA [
          <xref ref-type="bibr" rid="ref24">24</xref>
          ]. Similar U-inverted behavior
is common to most of the costs of non-material nature, in particular, social and environmental
costs [
          <xref ref-type="bibr" rid="ref25">25</xref>
          ]. The results also show that there is no significant influence of control variables (Lev,
l_SIZE, DVICTSS) on ROA.
        </p>
        <p>The overall content of the regression coeficient of Model 1 is that with an increase of 1
directly influencing the ROA, the last increase in the ratio will be increased. For example, if
SOFT is increased by 1, the ROA will increase by 1,65440 ⋅1006. And for indicators that have a
positive impact on ROA, their increase by 1 for ICT enterprises will result in corresponding
decrease of ROA (depending on the coeficient of regression).</p>
        <p>Table 5 indicates that the coeficient of determination (R-squared) of Model 1 is 0,047173.
This means only that 4,7% of the variation of ROA can be explained by the variation of the
independent variables (const, RDI, RDI2, SOFT, IPR, AIA, LEV, l_SIZE, DVICTSS).</p>
        <p>Model 2 (NPM). Model 2 can be interpreted through the following equation:
 =̂ −0, 274718 + 0, 0626252 1 − 0, 00669466 2 − 5, 13111 ⋅ 10−8 3 + 2, 00654 ⋅ 10−7 4 − 5, 88982 ⋅
10−8 5 − 0, 0630010 6 + 0, 0269143 7 − 0, 0517929 8
where:  ̂ – NPM;  1 −  8 – the same as in Model 1.</p>
        <p>Based on table 6, the most significant efect on NPM is changed to l_SIZE. Accordingly,
with the growth of the enterprise volume by 1 increases the value of the NPM indicator by
0,0269143. Significant at the 5% level in NPM explanation have regressors const, RDI, RDI2
and AIA. Also significant at the 10% level is the DVICTSS regression, which has an indirect
efect. Indirect efects on NPM are also afected by the RDI2 and AIA indicators. This means
that, as investments in such types of intangible assets increase, the corresponding (depending
on the regression coeficient) reduction of the dependent variable will occur. By comparing the
coeficient of Model 2 with RDI and RDI2, it is possible to note the existence of the upper limit
of investments in R&amp;D of Slovak ICT companies, after which their negative impact on NPM
will already be observed.</p>
        <p>Table 7 indicates that the R-squared of Model 2 is 0,01, a very low value and does not allow
to speak about the significant role of intangible assets in NPM provision. This means that 1,33%
of the variation of the NPM can be explained by the variation of regressors.</p>
        <p>Model 3 (ATO). Model 3 can be interpreted through the following equation:
 =̂ 2, 80330−1, 42622 1 −0, 134772 2 +2, 76920⋅10−6 3 +4, 61116⋅10−6 4 −4, 38715⋅10−7 5 −
0, 139781 6 − 0, 0951285 7 + 0, 150857 8
where:  ̂ – ATO;  1 −  8 – the same as in Model 1.</p>
        <p>For dependent variable ATO except for LEV and DVICTSS, all other regressions are significant.
In particular, l_SIZE significant at the 5% level, and all other regressions (const, RDI, RDI2, SOFT,
IPR and AIA) significant at the 1% level. Direct efects on ATO from the regression data are
RDI2, SOFT and IPR, while others are afected. In particular, as in Model 1 for ROA, making a
small amount of investments in R&amp;D of Slovak ICT companies has a negative impact on ATO.
Only their implementation from a certain volume, in particular, in the volume of RDI2, ensures

the growth of ATO. Based on an equal to 1,3 RDI2 growth by 1 increases the NPM value by
0,0269143. Table 9 indicates that the R-squared of Model 3 is 0,056. This means that 5,61% of
the variation of the ATO can be explained by the variation of regressors.</p>
        <p>Model 4 (ROE). Model 4 can be interpreted through the following equation:
 ̂= −1, 06067 − 2, 79903 1 + 0, 272431 2 + 5, 89712 ⋅ 10−6 3 + 8, 97938 ⋅ 10−7 4 − 1, 27997 ⋅
10−6 5 + 8, 94081 6 + 0, 0265371 7 + 0, 392670 8
where:  ̂ – ROE;  1 −  8 – the same as in Model 1.</p>
        <p>Model 4 has five statistically significant regressors – RDI, RDI2, SOFT, AIA and LEV (table 10).
All of them have the highest level of significance – 1%, therefore they have the greatest influence
on the dependent variable (ROE). The equation of Model 4 shows that most of the independent
variables (RDI2, SOFT, IPR, LEV, l_SIZE and DVICTSS) have a direct influence, and only two
variables (const, RDI and AIA) have a rotational influence on the ROE. As in Models 1 and 3,
Model 4 has a U-inverted relationship between R&amp;D and ROA, characterized by the need to
increase investment in R&amp;D of Slovakia ICT companies to ensure their positive impact on ROE.</p>
        <p>Table 11 indicates that the LSDV R-squared of Model 4 is 0,51. This is quite a high value
compared to the 1–3 models, but not enough to speak about the significant role of intangible
assets in providing of financial performance of ICT companies. This means that 51,61% of the
variation of the ROE can be explained by the variation of the regressors.</p>

      <title>6. Discussion</title>
      <p>
        The results obtained in the article partially confirm the conclusions of the analyzed works on the
role of intangible assets in the promotion of financial performance of high-tech companies. As
for some regressions, they are in conflict with such conclusions. The existence of a positive and
significant relationship between intangible assets and some financial performance measures was
confirmed, which is also set in the works of Li and Wang [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ], Dženopoljac et al. [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ], Zhang
[
        <xref ref-type="bibr" rid="ref15">15</xref>
        ]. The presence was also established of negative and significant impact of AIA on all financial
performance indicators, this confirms the results of the research [
        <xref ref-type="bibr" rid="ref16 ref17">16, 17</xref>
        ]. At the same time, the
direction and influence of diferent types of regressions used in the study are not the same in all
formed models, but depends on a particular kind of financial performance indicator. One of
the reasons for this is that the relationship between intangible assets on financial performance
may depend on macroeconomic factors, in particular, on the level of science capacity in the
industry and on the level of innovation in the country, which is noted by Qureshi and Siddiqui
[
        <xref ref-type="bibr" rid="ref16">16</xref>
        ]. Another reason for such results may be incomplete information about intangible assets
disclosed in the financial statements of Slovak ICT companies. In turn, this is a consequence of
the conservatism of the current methodology of recognizing and evaluating intangible assets,
which Zhang [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ] also points out, Radonić et al. [
        <xref ref-type="bibr" rid="ref19">19</xref>
        ]. Therefore, the findings of this study
confirm the proposal of Serpeninova et al. [
        <xref ref-type="bibr" rid="ref20">20</xref>
        ] regarding the necessity of expanding the criteria
for recognizing and the structure of financial reporting for high-tech companies regarding
intangible assets.
      </p>
      <p>
        The results of the survey refutes the conclusions of Gan and Saleh [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] on the positive impact
of the company’s size on the improvement of financial performance (ROA), but such an impact
was found with respect to NPM. The above confirms the hypothesis of Del Monte and Papagni
[
        <xref ref-type="bibr" rid="ref26">26</xref>
        ] that to increase the returns from intangible investments should be provided with their
proper quality level, not quantitative imitations. Therefore, an intangible investment policy of
ICT companies should be based not only on quantitative parameters, that is, not on the basis of
total investment in the company, but on the individual role of certain types of intangible assets
in improving of financial performance.
      </p>
      <p>The study has some limitations, which should be taken into account by other scientists when
evaluating the results of a study. Firstly, given the suficient breadth of the term “financial
performance”, a list of dependent variables used in the study can be specified. Second, the list of
independent variables used in a study can be expanded by uncapitalized intangible assets that
also afect the financial performance of Slovakia ICT companies. However, it is necessary to
separate from the composition of diferent types of expenses of ICT companies those expenses
connected with creation of intangible assets (client, ecological, social, etc.), as such data are
not in financial statements of companies. Third, to determine the role of intangible assets in
improvement of financial performance, research can be carried out not only on the examples of
companies of ICT industry, but also on the example of other branches of economy. This will
allow to carry out an interindustry comparison and establish in which areas of management of
enterprises should pay the most attention to development of an intangible investment policy.</p>

      <title>7. Conclusion</title>
      <p>This research was undertaken with the objective of comprehending the ramifications of
intangible assets on the financial performance of high-tech enterprises. The focus of this study was
the analysis of 180 Slovak ICT companies over the period spanning 2015 to 2019. This inquiry
gains particular pertinence against the backdrop of the pivotal role that the ICT sector plays in
propelling the development of the Slovak economy. The Slovak Government has proactively
established conducive institutional conditions to facilitate the growth of ICT companies and
has initiated specialized programs to incentivize investments in this sector.</p>
      <p>Panel data regression analysis served as the foundational methodology for this investigation.
The financial performance was characterized through four dependent variables: Return on
Assets, Net Profit Margin, Assets Turnover, and Return on Equity. For each of these indicators,
a distinct model was constructed, incorporating eight independent variables. The intangible
asset variables encompassed Research and Development Intensity, Research and Development
Intensity Squared, Software, Intellectual Property Rights, and Acquired Intangible Assets.
Additionally, three control variables were integrated: Leverage, Size, and a Dummy variable denoting
ICT sub-sectors, within the temporal scope of 2015 to 2019. The selection of the optimal panel
data parameter for each model was grounded in statistical tests, such as the F-statistics test,
Breusch-Pagan test, and Hausman test (Models 1 to 3 – pooled OLS model, Model 4 – Fixed
Efects Method). To assess the models’ compatibility with the generated data, the Normality test,
Autocorrelation test (Wooldridge test for autocorrelation), and Heteroscedasticity test (White
test, Walk test) were employed, substantiating the application of robust standard errors due to
partial model adequacy.</p>
      <p>The study’s hypothesis was afirmed to a certain extent through the outcomes of the panel
regression analysis. The results unveiled that not all categories of intangible assets wield a
significant positive influence on the financial performance of Slovak ICT companies. Specifically,
Research and Development Intensity (RDI), Research and Development Intensity Squared (RDI2),
and Acquired Intangible Assets (AIA) exhibited substantial impact across various degrees on the
four distinct financial performance indicators. This emphasizes the rationale for management to
channel investments into these specific categories of intangible assets for Slovak ICT companies.
Furthermore, the contrasting directions of influence of RDI and RDI2 on financial performance
indicators underscore the existence of a U-inverted relationship between R&amp;D investment
and the financial performance metrics. Depending on the model, RDI either operates beyond
the threshold of returns on R&amp;D investments or within it, while RDI2 exhibits the inverse
relationship. These findings ofer managerial insights into optimizing R&amp;D investments based
on the desired financial performance outcomes. Remarkably, across all models, Acquired
Intangible Assets (AIA) demonstrated substantial significance but negatively afected the financial
performance of Slovak ICT enterprises. This indicates the need for more expeditious integration
of these long-term intangible assets into the operational fabric of the companies.</p>
      <p>Furthermore, the research underscores the need for a comprehensive system to plan the
assimilation of intangible assets, tailoring them to the company’s exigencies as a core component
of its intangible investment strategy. The analysis of control variables, including Leverage,
Size, and Dummy variable for ICT sub-sectors, demonstrated selective impact on financial
performance indicators. Notably, only the variable l_SIZE exhibited a significant influence
on Net Profit Margin (NPM) and Assets Turnover (ATO), with implications for managerial
considerations in optimizing these metrics. The variable DVICTSS exhibited limited significance
on NPM, while LEV afected Return on Equity (ROE). These findings underscore the nuanced
and selective nature of control variables’ influence on various financial performance indicators,
with no discernible efect on Return on Assets (ROA).</p>
      <p>In the broader context, this study serves to illuminate the intricate relationships between
intangible assets and financial performance in the ICT sector. The insights garnered herein
have the potential to inform prudent decision-making within the domain of intangible asset
investments and their subsequent impact on financial performance for Slovak ICT companies.
Furthermore, this research ofers valuable insights for policy and strategic adjustments aimed
at fostering the incorporation of long-term intangible assets into business operations, thus
enhancing financial performance. As the ICT sector continues to evolve and shape the Slovak
economy, these findings can serve as a compass guiding efective strategies for leveraging
intangible assets in this dynamic landscape.</p>
      <p>As the global business environment continually evolves, future research endeavors could delve
deeper into the interplay between various intangible asset categories and financial performance
across diferent industries and geographical contexts. Such investigations would not only enrich
the existing body of knowledge but also provide actionable insights for enterprises seeking to
optimize their financial performance through targeted intangible asset investments.</p>
