The indirect effect of disclosure on firm value through information asymmetry is also relevant to the hypothesis. The findings suggest that higher disclosure provides great benefits for the companies as well as investors and lenders.

Subjects: Finance; Business, Management and Accounting; Industry & Industrial Studies Keywords: recursive correlation; voluntary disclosure; information asymmetry; cost of capital; firm value 1. Introduction This study aims to examine whether complete and numerous disclosures by a company are beneficial for investors as well as for the company Conveying complete and ample information to the public is expected to reduce the information gap amongst decision maker (Bertomeu et al., 2021), lower the cost of capital (Chen et al., 2022; Michaels & Grüning, 2017; Botosan & Plumlee, 2002), and increase public trust to the company (Sheu et al., 2010); thus, it increases firm value (tTemiz, 2021; McMullin, 2019). Specifically, Wong and Zhang (2022) reveal that the market reacts to information voluntarily disclosed by a firm which reflected in the higher stock price. This study specifically fills the gap to explore whether the companies benefit greatly as a consequence of the large costs incurred to produce complete and multiple disclosures in their financial reports (Coffie and Bedi, 2018), and whether investors obtain the most benefit from disclosure of financial information. Previous research has focused more on the benefits of financial reports only for the investors (Dutta and Nezlobin, 2017) and the companies (Michaels & Grüning, 2017). Meanwhile, those considering costs and benefits for companies as well as investors in a comprehensive model are still limited. It is argued that large disclosures not only cause large costs for the company (Coffie and Bedi, 2018) but also provide great benefits (Bertomeu et al., 2021), a reduction in the cost of capital (Chen et al., 2022; Cuadrado-Ballesteros et al., 2016; J.E. Core et al., 2015), and an increase in company value (Cianciaruso & Sridhar, 2018; McMullin, 2018). Besides, the generous disclosures reduce information imbalance which benefits investors. Therefore, investors ask for a lower cost of capital (implicitly showing benefits also for the companies; Cheynel, 2013; Botosan, 2006). To comprehensively investigate the costs and benefits of financial reporting information for companies and investors at the same time in one financial reporting period, this study investigates the correlation between disclosure, information asymmetry, cost of capital, and firm value in one comprehensive recursive model. It is suggested that the correlation between disclosure, information asymmetry, cost of capital, and firm value is unidirectional dependency. Hence, for any given values of voluntary disclosure, values for information asymmetry, cost of capital, and firm value can be determined sequentially rather than jointly. Therefore, testing the relationship separately between two factors, supposing that, between voluntary disclosure and information asymmetry only or between voluntary disclosure and cost of capital only, without examining the effect of this relationship on firm value, leads to a cost–benefit analysis inequality of voluntary disclosure to companies and investors. The costs and benefits of disclosure need to be viewed equally from both the company and investors. The negative relationship between voluntary disclosure and information asymmetry (Michaels & Grüning, 2017) reflects the high costs borne by investors (Cheynel, 2013). This relationship also indicates large benefits experienced by the company as a result of low disclosure. For this reason, information asymmetry is higher, or higher costs are experienced by the company. However, the investors perceive that the benefits are high resulting from high disclosure and low information asymmetry. The negative relationship between disclosure and cost of capital (He et al., 2019; Alves et al., 2015; Mangena et al., 2014) also shows the same result. High disclosure and low cost of capital cause the costs to Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 2 of 18 be borne by investors to be greater, while the company enjoys the benefits of a low cost of capital. Conversely, low disclosure and high cost of capital generate large costs for the company as a result of the increased risk perceived by investors. This relationship does not fully describe the costs and benefits felt by the company and investors at the same time. By testing the recursive relationship of these four variables at once, it provides a comprehensive illustration of the costs and the benefits experienced by investors and companies with voluntary disclosure. 2. Background The issue of the correlation between voluntary disclosure, information asymmetry, cost of equity capital, and firm value is not a contemporary concern that has been partially tested for more than two decades. The seminal papers of Leuz and Verrecchia (2000) and Healy and Palepu (2001) had explained the relationship of these four variables which led to the idea of recursively testing the four variables in one comprehensive model. Leuz and Verrecchia (2000) explained that higher financial information disclosures reduce information asymmetry and the cost of equity capital. Consistently, Healy and Palepu (2001) enlightened that the demand for disclosure increases due to agency conflict and high information asymmetry between managers and fund owners as reflected in higher cost of capital and lower share prices. Based on these two seminal papers, it can be discerned that information asymmetry and cost of capital mediate the relation between disclosure and firm value. Increased disclosure encourages lower information asymmetry and cost of capital, thereby rising firm value. Previous research has tested empirically and partially the association between voluntary disclosure, information asymmetry, cost of equity capital, and firm value. In the early period, Botosan (1997) showed a negative relationship between disclosure and the cost of capital. The higher the level of disclosure is, the lower the cost of capital will be. Recent empirical research supports the results of previous research in which the relationship between disclosure and information asymmetry and the cost of capital is negative. Michaels and Grüning (2017) examined the relationship between disclosure, information asymmetry, and the cost of capital. Their results showed a negative association between voluntary disclosure and information asymmetry and between voluntary disclosure and the cost of corporate capital in Germany for the 2013/2014 period. He et al. (2019) investigated the relationship between disclosure and cost of capital by using two types of disclosure, namely mandatory and voluntary disclosures. The results indicated that each of these types of disclosures affects the cost of capital. Previously, Mangena et al. (2014) also tested mandatory disclosure and voluntary disclosure together on the cost of equity. The results indicated that the interaction between mandatory disclosure and voluntary disclosure decreases the cost of capital. Alves et al. (2015) also examined the effect of voluntary disclosure on information asymmetry. It is found that increasing voluntary disclosure decreases information asymmetry. Besides, Blanco et al. (2015) examined the effect of mandatory disclosure on the cost of capital. Their finding revealed that the operating segment disclosure has a significant negative effect on the cost of capital. Supporting Healy and Palepu (2001), Fosu et al. (2016) examined the effect of information asymmetry on firm value. The results showed that low information asymmetry increases firm value during the financial crisis in the UK in the 2007/2009 period. In contrast to normal conditions, during the crisis, the company’s long-term debt has increased since the currency rate was uncertain, the purchasing power of one country’s currency against the currencies of other countries has decreased. Under this condition, information asymmetry is usually increased and firm value is decreased. Aligned with Fosu et al. (2016), Huynh et al. (2020) examined the correlation between information asymmetry and firm value of companies listed on the Vietnam stock exchange. In contrast to Fosu et al. (2016) who took a sample of companies in the UK, Huynh et al. (2020) took a sample of companies listed in Vietnam since they had a high debt ratio. The results showed that information asymmetry is negatively related to firm value. However, lower information asymmetry increases firm value. McMullin (2019) examined the effect of disclosure on firm value and found that increasing mandatory disclosure increases firm value. In line with Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 3 of 18 McMullin (2018), the results of Cianciaruso and Sridhar’s (2018) research reported that an increase in mandatory and voluntary disclosure increases firm value. Contrary to these studies, some previous studies in the early period did not support a negative relationship between voluntary disclosure and information asymmetry as well as between voluntary disclosure and the cost of equity capital. Botosan (1997) concluded that the correlation between disclosure and the cost of capital is feeble. According to Zhang (2001), differences in the results of previous studies are caused by the amount of disclosure depending on certain conditions and factors, such as disclosure costs, variations in earnings, etc. Botosan and Plumlee (2002) have not identified this negative association either. Several recent studies have shown the same results. Lopes and de Alencar (2010) stated that the frail correlation between disclosure and the cost of capital was influenced by environmental factors such as changes in financial accounting standards. Elena et al. (2012) and Cuadrado-Ballesteros et al. (2016) found that accounting reporting standards do not affect the quality of reports and also the cost of capital. These findings inform that the effects of disclosure, capital costs, and information asymmetry are inconclusive and become an interesting topic for further study. This study aims to investigate the relationship between voluntary disclosure, cost of capital, information asymmetry, and firm value in a comprehensive recursive model. It contributes to advancing the disclosure accounting research in terms of developing research methodology to support the negative correlation between disclosure and cost of capital and information asymmetry as well as the negative relationship between information asymmetry and cost of capital and firm value. Some previous studies have partially tested the relationship between these variables. We argue that there is unidirectional dependency among the information asymmetry, cost of capital, and such firm value; hence, for any given value of voluntary disclosure, values for information asymmetry, cost of capital, and firm value can be determined sequentially rather than jointly. This study is the first one to test the unidirectional correlation between voluntary disclosure, information asymmetry, cost of capital, and firm value in one comprehensively recursive model. Previous studies have examined the simultaneously direct correlation between variables in an OLS model. This present study recursively examines the relationship between these variables in one comprehensive recursive model. The novelty of this study can be identified through the enhancement of a model framework to show the cost and benefit of disclosure for companies, investors and lenders in a comprehensive recursive model. 3. Theoretical review and hypothesis development Agency theory broadly describes the connection between the variables tested in this study. First, it explains the relationship between disclosure, principal and agent, in which the principal and agent have the respective interests that need to be fulfilled through financial reporting. Principals expect them to obtain complete information regarding the company since this is related to the costs they have spent to invest. On the other hand, the authority that agents have over company information permits them to use the information for their benefit. Agent authority as the owner of information allows them to manipulate the company’s financial statements by selecting information that meets their interests and keeping the information private (Stocken & Verrecchia, 2004). It induces conflict of interest between agent and company’s owner cause of imbalance amount of information shared between investors and agents for decision-making (Hazaea et al., 2022). The standards or regulations that govern the financial reporting system are designed to be aware of the authority and interests of these principals and agents (Bertomeu & Magee, 2015). Previous research on the relationship between voluntary disclosure, information asymmetry, cost of capital, and firm value has shown different results. 3.1. Disclosure and information asymmetry The problem of information asymmetry causes the market to be inefficient. When agents have more information than is available to the public, then the agent’s assessments and predictions on the company’s performance become more accurate than the public. This condition has different Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 4 of 18 implications for companies and investors. Companies are encouraged to leave equity capital and choose debt capital (Shen, 2014). From the investor’s side, the issuance of new equity is likely to be lower. Hence, the wealth is shifted from existing shareholders to the new ones. Consequently, a lower price is a good reason for existing shareholders to reject a new investment that could generate positive net present value. In this case, the external financial costs become a burden for a company with higher asymmetric information. Several past research supports those arguments. Leuz and Verrecchia (2000) and Chiyachantana et al. (2013) found that disclosure can reduce information asymmetry. Chang et al. (2008) proved that increased exposure followed by increased analysts results in a lower cost of information asymmetry and has implications for increasing market capitalization. Renhui et al. (2012) pointed out that high disclosure can reduce information asymmetry and the cost of capital. Buskirk (2012) states that the relationship between disclosure and information asymmetry depends on the disclosure attributes being tested so that the results can be different. Agarwal et al. (2015) argue that by examining the investor relationship variable, it is found that effective investor relations can encourage increased levels of disclosure and reduce information asymmetry. Cuadrado-Ballesteros et al. (2016) proved that companies that increase disclosure of financial and social information tend to decrease information asymmetry. However, Cheynel and Levine (2020) demonstrated a different conclusion regarding the effect of disclosure on information asymmetry by using Mosaic theory. Investors are provided with a lot of public information that makes it easier for them to make decisions. However, what seems to be a concern is that high public disclosure increases information asymmetry if it is not accompanied by private disclosure. H1: Higher disclosure reduces information asymmetry. 3.2. Disclosure and Cost of Capital (CoC) We view the cost of capital from two viewpoints, from investor and company views. For investors, the CoC is the rate of return demanded by investor and lenders from their investment and loan they give (Vitolla et al., 2019). For the company, the CoC is companies’ expected return on their potential project or business prospect. Hence, the cost of capital reflects a trade-off between risk and return. When investors and lenders feel the risk is high, they will ask for a high CoC. Companies can increase bonding costs by providing as much information as possible about the investment being worked on. High and relevant information disclosure helps companies to reduce the level of risk perceived by investors and lenders so as to reduce the CoC (Lambert et al., 2007). Prior studies had supported those statement. Botosan and Plumlee (2002) pointed out that high disclosure causes an increase in the cost of capital. Cheynel (2013) mathematically formulated the effect of voluntary disclosure on cost of capital. Relying on voluntary disclosure, investors intend to avoid risk and increase return, so that, the more information obtained, the higher investor confidence in the company, which is reflected in a lower cost of capital. Lopes and de Alencar (2010) noted that increasing the number of disclosures by registered companies in Brazil can lower the cost of capital. Li (2010) proved that disclosure under IFRS is able to reduce the cost of capital. A similar point was also confirmed by Apergis et al. (2011) that an increase in the quality of accounting disclosure can increase expected cash flows, which then reduce the cost of capital. Furthermore, Embong et al. (2012) mention that the negative relationship between disclosure and the cost of capital is more significant in large companies. Renhui et al. (2012) also demonstrated a negative relationship between high disclosure of information asymmetry and the cost of capital. Elena et al. (2012) examined the effect of voluntary disclosure on the cost of capital and revealed that increasing voluntary disclosure lowers the cost of capital. Besides, Mangena et al. (2014) documented the effect of financial disclosures on the cost of capital. John Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 5 of 18 E. Core et al. (2014) reported that the cost of capital is decreased with increased disclosure in a sample of 35 countries from 1990 to 2004. Blanco et al. (2015) discovered a negative relationship between segment disclosure and cost of capital. He et al. (2019) confirmed that the cost of capital is affected by both voluntary disclosure, periodic mandatory disclosure, and event-driven disclosure. Setiany and Suhardjanto (2021) show that higher disclosure lowers the cost of capital. H2: Higher voluntary disclosure reduces the cost of capital. 3.3. Disclosure and firm value Voluntary disclosure is the provision of information by management beyond the mandatory disclosures regulated by financial accounting standards, where the information is believed to be relevant to reveal the financial and non-financially firm performance. Cianciaruso and Sridhar (2018) showed mathematically the effect of mandatory disclosure on firm value. The results revealed that financial information disclosure increases firm value in the future. Sheu et al. (2010) and Chen and Lee (2017) demonstrated that such disclosure affects firm value in companies in Taiwan.. Jiao (2011) also mentioned the effect of mandatory disclosure on firm value in America. Faisal et al. (2020) specifically observed the impact of disclosure on firm value. The results showed that higher voluntary disclosure increases firm value. Consistent with the previous results, tTemiz (2021) and Assidi (2020) illustrated a positive significant effect of voluntary disclosure on firm value. However, different findings are confirmed by Sumatriani et al. (). Their results indicated that disclosure does not increase the firm value of companies listed on the stock exchange of Indonesia, Malaysia, and Thailand for the period 2012–2015. H3: Higher voluntary disclosure increases firm value. 3.4. Disclosure, cost of capital, information asymmetry, and firm value It seems challenging to find literature showing the relationship between these four variables in a comprehensive model. Several research results support the relationship of these four variables separately. Bertomeu et al. (2021) mathematically explained that higher voluntary disclosure provided a higher benefit for investor in the form of lower information asymmetry and for the company, i.e., lower cost of capital. Studies by Fosu et al. (2016) and Alves et al. (2015) had shown that the information asymmetry is expensive for the companies and investors due to adverse selection costs which prevent the companies from increasing company value and harming investors as identified from the high difference in selling and buying prices of shares. In this situation, the adverse selection cost forces companies to make less optimal investment decisions that seem to be unfavorable for firm value (Fosu et al., 2016). Therefore, financing with equity becomes more expensive than debt in conditions of high information asymmetry (Fosu et al., 2016; Myers, 1984). This theory is relevant to several studies, such as Easley and O’Hara (2004) which found that complete disclosure decreases the cost of equity capital because 1) it reduces the estimation risk for investors or 2) reduces the transaction costs due to the lack of information asymmetry. Complete disclosure increases expected cash flow which leads to lower capital costs (Apergis et al., 2011). This explanation is aligned with He et al. (2019). More specifically, voluntary disclosure has a critical role in reducing information asymmetry (Alves et al., 2015). Regarding testing the implications for firm value, Agarwal et al. (2015) and Chang et al. (2008) identified a decrease in the cost of capital as a consequence of increased disclosure and ultimately an increase in market capitalization. Increasing the quality and quantity of disclosure is a consequence of the successful implementation of IFRS in lessening the cost of capital (Li, 2010). Some previous studies showed the association of two or three variables only. Setiany and Suhardjanto (2021) investigated the relationship between disclosure, cost of equity capital, and Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 6 of 18 information asymmetry in an emerging market like Indonesia. They confirmed that the cost of equity capital is decreased by reducing information asymmetry through increased disclosure. Cuadrado-Ballesteros et al. (2016) examined the correlation between information asymmetry, disclosure, and cost of equity capital. He stated that companies with low information asymmetry due to increased disclosure of financial and social information make the risk of estimation smaller and reduce the cost of capital with increased market liquidity. Liu and Chen (2015) illustrated the relation between disclosure, information asymmetry, and firm value. They showed that high disclosure of financial information can reduce information asymmetry and increase financial transparency, thereby increasing the value of companies listed on the American Stock Exchange, namely on the NYSE, AMEX, and Nasdaq. Fosu et al. (2016) examined the effect of information asymmetry on firm value in the UK. Their results supported their proposed hypothesis that high information asymmetry reduces firm value. In particular, Huynh et al. (2020) examined the relationship between information asymmetry and the value of companies listed on the Vietnam Stock Exchange. In line with Fosu et al. (2016), their research findings showed that information asymmetry is negatively related to firm value. It means that the information asymmetry of companies in Vietnam is high and firm value is low. The information asymmetry of companies listed on the Vietnam Stock Exchange is relatively higher than that of companies listed on the stock exchanges of developed countries. H4: Higher voluntary disclosure decreases the cost of capital, in that way increasing firm value. H5: Higher voluntary disclosure decreases information asymmetry, in that way increasing firm value. To summarize previous studies, as Hazaea et al. (2022) way, this paper explains the top 10 leading papers regarding the relationship between voluntary disclosure, cost of capital, information asymmetry, and firm value as stated in Table 1. 4. Research methods and materials 4.1. Sample and data The samples were 1920 firm-years of non-financial issuers listed on the Indonesia Stock Exchange in the period 2012–2019 for which audited financial statements are presented. The samples were selected by random sampling method using the Slovin formula: n = N/(1 + (N x e 2 )), where n is the minimum sample size (1920), N is the population (4160), and e is the error margin (0.01675). The data used were a voluntary disclosure index obtained employing a self-constructed index. Stock market data were in the form of closing prices, bid and ask prices, and a number of shares outstanding, as well as company financial data, to calculate the cost of capital. Bid and ask price, and closing price data were obtained from data provider www.investing.com. We calculated the eight-year average bid–ask spread based on monthly data from 2013 to 2020. The bid price, ask price, and closing price data taken were the average annual data around February to June each year. The average company published an annual report during these months. These ways are consistent with another recent study that used the average bid–ask spread as a proxy for information asymmetry. As in Michaels and Grüning’s (2017) study, we included the natural logarithm of the bid–ask spread measure for information asymmetry. 4.2. Definition and operationalization of variables Firm Value. Firm value reflects the composition of market value against book value of asset (Diantimala et al., 2021). Higher market value of equity pronounces higher firm value. Hence, firm value is calculated by using the Tobin’s Q ratio, the market value of equity to book value of Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 7 of 18 information asymmetry (coef. = 0.005), in that way, improves firm value (coef. = —1.973). The result in line with Liu and Chen (2015), higher disclosure of financial information reduces information asymmetry and then increase financial transparency, thereby raising the value of companies. As a result, these findings support hypothesis 5 (H5) that higher voluntary disclosure decreases information asymmetry, in that way increasing firm value. In general, the results show that complete and numerous disclosures by a company are beneficial for investors in form of lower information asymmetry, as well as for the company in the form of lower cost of capital and higher firm value Conveying complete and plenty information to the public reduces the information gap amongst market players, between management and investors, and between management and lenders (Michaels & Grüning, 2017; Helay and Palepu, 2001), lower the cost of capital (Michaels & Grüning, 2017; Botosan, 1997; Francis et al., 2005), and increase public trust to the company (Sheu et al., 2010); thus, it increases firm value (McMullin, 2018). The results specifically fill the gap that the companies benefit greatly as a consequence of the large costs incurred to produce complete and multiple disclosures in their financial reports (Coffie and Bedi, 2019), and investors obtain the most benefit from disclosure of financial information. 6. Conclusion This study aims to investigate whether more complete and numerous voluntary disclosures by a company are beneficial for investors as well as for the company. Conveying complete and plentiful information to the public is expected to reduce the information gap between market players, management and investors, and management and lenders, lower the cost of capital, and increase public trust in the company, thereby increase firm value. Therefore, this study examines the impact of voluntary disclosure on cost of capital and information asymmetry, and then on firm value in a comprehensively recursive model. We argue that there is unidirectional dependency among the information asymmetry, cost of capital, and such this firm value, for any given values of voluntary disclosure, values for information asymmetry, cost of capital, and firm value can be determined sequentially rather than jointly. The unidirectional dependency amongst exogenous and endogenous variables are the unique characteristic of recursive model. The results show that the negatively direct effect of disclosure on information asymmetry and cost of capital is consistent with the hypothesis. The indirect effect of disclosure on firm value through the information asymmetry and cost of capital is also relevant to the hypothesis. The findings suggest that higher disclosure provides great benefits for the companies as well as investors and lenders. Increasing disclosure reduces information asymmetry and the cost of capital, thereby increasing firm value. In regard to the direct effect, the results showed that voluntary disclosure has a significantly negative effect on the cost of capital and information asymmetry as well as has a significant positively impact on firm value. Higher voluntary disclosure significantly reduces information asymmetry. Companies that offer more financial and non-financial information voluntarily, tend to experience lower information asymmetry. The more information that is conveyed to the public, the information gap between market participants who have superior information and market participants who do not have superior information is getting smaller. Therefore, the more information the company conveys, the price speculated by investors who do not have superior information is closer to the price offered by superior market participants. It supports hypothesis 1. Furthermore, investor rely on voluntary disclosure to avoid risk and increase return, so that, the more information obtained, the higher investor confidence in the company, which is reflected in a lower cost of capital. The voluntary disclosure gives a significantly negative effect on the cost of capital. This result is consistent with previous literature which state that revealing that increasing disclosure lowers the cost of capital. An increase in the quality of accounting disclosure rises expected cash flows, which then reduces the cost of capital and increase firm value. Thus, the results confirm hypothesis 2. Moreover, the voluntary disclosure has a significantly positive effect on firm value. It is meant that increased voluntary disclosure escalates firm value. The result supports hypothesis 3 (H3). Diantimala et al., Cogent Business & Management (2022), 9: 2154489 https://doi.org/10.1080/23311975.2022.2154489 Page 14 of 18 Concerning the indirect effect, the results revealed that higher disclosure significantly affects firm value indirectly through the cost of capital. The sign of the relationship between disclosure and cost of capital is negative. It is consistent with our expectation. However, the sign of the relation between cost of capital and firm value is positive, which is not coherent with our prediction. An increase in voluntary disclosure decreases the cost of capital, in that way, decreases firm value. This finding is inconsistent with previous research, reporting that a decrease in the cost of capital higher firm value. These results showed that higher disclosure reduces the cost of capital, which unfortunately, decreases the firm value. The results fail to support hypothesis 3. Moreover, the results illustrate that disclosure significantly influences firm value indirectly through information asymmetry. Increasing disclosure decreases information asymmetry while decreasing information asymmetry increases firm value. In line with previous results, higher disclosure of financial information can reduce information asymmetry and improve financial transparency, thereby increasing the value of companies. Companies with higher disclosure of financial and social information lessen the risk of estimation and the cost of capital with increased market liquidity caused by an increase in firm value. Therefore, these results accept hypothesis 4. In addition, pairing 7 reveals that disclosure significantly affects firm value indirectly through information asymmetry at the 10% level. The sign of the correlation between voluntary disclosure and information asymmetry is negative, as also the correlation between information asymmetry and firm value. These signs are consistent with our expectation. Based on the signs, we conclude that increasing voluntary disclosure decreases information asymmetry, in that way, improves firm value. As a result, these findings support hypothesis 5 (H5).
