Purpose: This research examines the influence of business strategy and intellectual capital on firm performance and bankruptcy risk of Oman's non-financial sector companies.Design/methodology/approach: The data comprises 380 firm-year observations collected from 2015 to 2019 for the non-financial sector companies listed on the Muscat Securities Market. This study measures business strategy using the Miles and Snow typologies and Porter's strategies as alternative measures. The study uses the Granger-causality test to measure the bi-directional causality between independent and dependent variables. The authors use alternative measurements of business strategy and 2SLS/IV estimation to validate the OLS results.Findings: According to the Miles and Snow typologies, most of Oman's non-financial firms were analyzers. The empirical results show a negative relationship between business strategy and return on equity (ROE), suggesting defender-type strategy leads to an increase in firm performance. The OLS results show no influence of A-VAIC on firm performance and Altman-Zscore. The structural capital efficiency is positively associated with ROA, and AltmanZscore consistent with the hypothesized relationship. The Granger causality test shows no inference of causality between any independent and dependent variables except forZscore and CEE.Research limitations/implications: The business strategy results from the firm performance and bankruptcy risk models are valuable to the researchers from an emerging market and non-financial companies' perspective. Oman's diversification strategy of its economic activities through non-financial sector companies receives an impetus through the findings of this study. As this study is limited to Oman's non-financial sector companies, future research on business strategy impact can be extended to the financial sector, other GCC, and emerging countries.Originality/value: The findings of this study contribute to the sparse literature on business strategy in an emerging market like Oman. This study enriches the knowledge of business strategy typologies proposed by Miles and Snow, and Porter. It also contributes to the extant literature on firm performance and bankruptcy risk.

Purpose: The purpose of this study is to empirically investigate the relationship between intellectual capital and corporate governance of Oman's financial sector companies. Intellectual capital has been found to successfully contribute to the economic wealth creation of firms in germane literature. Unfortunately, financial statements do not necessarily capture and reflect the contributions of intellectual capital, thereby leading to an information asymmetry between companies and users of financial statements. The research also investigates the relationship between corporate governance and intellectual capital efficiency across various financial subsectors.Design/methodology/approach: Data are collected from annual reports available on Muscat Securities Market for 31 listed financial sector companies for the period 2012 to 2016 and analyzed using a multiple regression model. Intellectual capital is measured using Pulic's efficiency measure of value-added intellectual coefficient (VAIC). Corporate governance individual components such as board characteristics, audit committee characteristics and ownership structure are presented as independent variables.Findings: The findings suggest that board size and frequency of audit committee meetings have a significant association with the intellectual capital efficiency of Oman's financial sector. VAIC and human capital efficiency of banks are also significantly influenced by most of the corporate governance mechanisms; however, other subsectors do not report such findings. Corporate governance of banks in comparison to other subsectors effectively engages in utilizing the potential of intellectual capital efficiency. Agency theory and resource dependency theory find limited support as a result of this study. The GMM results are not robust to the alternative instruments.Research limitations/implications: The sample size is small as the study is limited to the listed financial sector of Oman. Future studies can be extended to include all of Oman's or GCC’s listed companies. Additionally, the intellectual capital is measured using the construct of VAIC which suffers some limitations and can be overcome using other tools such as content analysis.Practical implications: The findings of this study suggest that Oman's regulators can create an awareness strategy on highlighting the importance of intellectual capital for companies (board of directors and managers), investors, debtors and creditors. Further, Oman's Capital Market Authority and Muscat Securities Market need to strengthen the regulations related to intellectual capital.Originality/value: This study extends intellectual capital and corporate governance literature by presenting the research outcome for Oman's financial sector. It is useful for Oman's financial sector companies to direct corporate governance measures for driving value creation of firms through the management of intellectual capital efficiency.

Purpose: The readability of annual reports is an important feature that determines the quality of communication between a firm and its stakeholders. Extant literature has demonstrated that readability characteristics of annual reports are crucial in facilitating the investor's ability to process and analyze information, resulting in higher firm performance and lower agency costs. This study examines the relationship between annual report readability, agency costs and the firm performance of listed financial sector companies in Oman.Design/methodology/approach: Using a sample of 150 firm-year observations of listed financial sector companies on the Muscat Securities Market (MSM) over the period 2014 to 2018, a panel regression analysis is used, along with the system generalized method of moments (GMM) estimation to address endogeneity concerns. The readability of annual reports is proxied by the length of the annual report, the Flesch reading ease and the Flesch–Kincaid index.Findings: The ordinary least squares (OLS) results suggest that readability proxied by the length of the annual report has no significant relationship with agency cost, return on assets (ROA) or stock returns. The OLS results are confirmed through the system GMM estimation model for agency costs, Tobin's Q and stock returns. Easier-to-read annual reports measured by the Flesch reading ease demonstrate high asset utilization ratio and Tobin's Q. These results emphasize Flesch reading ease measure in explaining the economic significance of agency cost and Tobin's Q. In contrast, difficult-to-read annual reports are observed for firms with high ROA.Research limitations/implications: The study is limited to the financial sector. Its generalizability could be extended to a similar sector or countries with features similar to Oman. Future studies on readability could be extended to other sectors of Oman, and financial firms with easier-to-read annual reports show a high Tobin's Q, which reflects the confidence of investors in the stock market. These findings may encourage policymakers to regulate the readability features of annual reports and influence the reporting quality of financials and disclosures also including cross-country comparisons.Practical implications: Financial firms with easier-to-read annual reports show a high Tobin's Q, which reflects the confidence of investors in the stock market. These findings may encourage policymakers to regulate the readability features of annual reports and influence the reporting quality of financials and disclosures.Originality/value: While the study extends prior literature on readability, agency costs and firm performance, it is also one of the first to examine the financial sector of an emerging country, namely, Oman. The study supports the obfuscation hypothesis through the association of readability measure with agency cost. Unlike prior research that has focused on common computational linguistic literature, this study uses three proxies for readability to assess information quality.

Purpose: – The purpose of this paper is to evaluate existing studies on the relationship of corporate governance with firm performance in different regions and address the need for similar analysis for the Gulf Coperation Council (GCC) sector. The banking sector comprises the conventional and Islamic banks in the GCC sector and is important due to their ability to bring stability to this region. Existing studies that measure the relationship of GCC sector conventional banks and firm performance are limited. This study proposes a need for future research on corporate governance in the GCC region.Design/methodology/approach: – This paper will review and analyze the different empirical and theoretical contributions in establishing the relationship between corporate governance and firm performance.Findings: – This paper will create a focus for future research of measuring the impact of corporate governance mechanism on firm performance. The regulators will be encouraged to focus on more research studies for the GCC sector development in the field of corporate governance of the banking sector.Research limitations/implications: – The existing studies are valid and practicable for the region under study, and the results need not be applicable for other business environments. In addition, the evolving business and economic environment have always brought about inconsistent conclusions; thus, the period of study can always give varied results.Practical implications: – The analysis undertaken in this paper will address the literature gaps for the GCC banking sector and play an instrumental role for future studies by theoreticians and regulators.Originality/value: – This paper identifies the literature gaps for the GCC region and analyses the most applicable existing studies that can be useful for the banking sector corporate governance improvement. This paper will create opportunities for the future researchers.

Purpose: This study examines the impact of intellectual capital efficiency and corporate governance mechanisms on the annual report readability of Oman's financial sector companies.Design/methodology/approach: The study uses a sample of 150 firm-year observations of listed financial sector companies in the Muscat Securities Market, Oman, from 2014 to 2018. Flesch Reading ease and Flesch Kinkaid Index are used as proxies for annual report readability. As part of sensitivity analysis, the study also uses the natural logarithm of annual report pages as alternative readability measures. The investigation is conducted using random effects regression analysis and supported with system GMM estimation for robustness.Findings: The findings of this study demonstrate a decrease in intellectual capital efficiency associated with better readability of annual reports for the financial sector firms. Alternatively, banks report a positive association of intellectual capital efficiency with the Flesch Reading ease score of the annual report. The structural capital and capital employed efficiency are also found to be negatively associated with annual report readability. Corporate governance mechanisms such as dispersed ownership and audit committee size also result in easy-to-read annual reports that support agency theory.Research limitations/implications: The research was conducted for financial firms of Oman, and thereby the findings can be generalized to the financial sector of countries with similar settings, such as the Gulf Cooperation Council (GCC) region.Practical implications: The policy implications arising from this study suggest a strengthening of the intellectual capital efficiency and corporate governance mechanisms to improve the readability of the firms and thereby increase investor confidence.Originality/value: This paper's uniqueness is in the model used to investigate the impact of intellectual capital efficiency and corporate governance mechanisms on the annual report readability of an emerging market.
