1 Chapter - VI Profitability Analysis of Indian General Insurance Industry As a result of the various reforms introduced by the Government of India in the insurance sector, private companies have made their entry into the field. It has thrown a new challenge before the public sector companies. Now it has become quite tough for the companies to work in a competitive environment. It has resulted in reduction of product prices, increases in distribution cost and better service quality. There is uncertainty regarding the effect of these reforms on the profitability of these companies which is important for the safety and soundness of insurance industry. 6.1 Concept of Profitability The term profit is an accounting concept which shows the excess of income over expenditure viewed during a specified period of time. Profit is the main reason for the continued existence of every commercial organization. On the other hand, the term 'profitability' is a relative measure where profit is expressed as a ratio, generally as a percentage. Profitability depicts the relationship of the absolute amount of profit with various other factors. Profitability is the most important and reliable indicator as it gives a broad indicator of the ability of a insurance company to raise its income level. In practice, executives define profits as the difference between total earnings from all earning assets and total expenditure on managing entire asset-liabilities portfolio (Kaur and Kapoor, 2007). 6.2 Drivers of Profitability To analyze the drivers of profitability, it is useful to decompose ROE into its main components. Profits are determined first by underwriting performance (losses and expenses, which are affected by product pricing, risk selection, claims management, and marketing and administrative expenses); and second, by investment performance, which is a function of asset allocation and asset management as well as asset leverage. The first fork of the decomposition shows that an insurer s ROE is determined by earnings after 155

2 taxes realized for each unit of net premiums (or profit margin) and by the amount of capital funds used to finance and secure the risk exposure of each premium unit (solvency). The after-tax profit margin equals the pre-tax profit margin times one minus the corporate tax rate. The tax rate depends upon individual tax strategies and is otherwise an exogenous parameter of the industry. The pre-tax profit margin is the sum of the underwriting result (or underwriting margin) and the investment result. The investment result is determined by total investment yield (relative performance including realized capital gains) multiplied by invested assets (asset leverage).the underwriting result - in per cent of net premiums - is determined by the loss ratio, the expense ratio (Rudolf, 2001). The benefit of this type of decomposition is to separate the various factors affecting profitability, isolating them for further analysis. Though they will be analyzed separately, they are interrelated through the decision-making processes of insurers. 6.3 Comparative Profitability Analysis of the Public and Private Sector General Insurance Companies in the Post-reform Period Claim Ratio Claims incurred ratio may be defined as total net incurred claims divided by net written premium (NWP). This indicator is a good complement to the picture of economics, client value and service quality of the various insurance schemes. The acceptable level for this indicator cannot be determined, but generally, the higher it is, the better it would be. 156

Sig.

The sector-wise analysis shows that the claim incurred ratio of the public sector 157

4 general insurance companies is higher than that of the private sector general insurance companies throughout the study period. Among the public sector companies, United India Insurance Co. Ltd. showed a maximum average claim ratio of per cent followed by National Insurance Co. Ltd. and Oriental Insurance Co. Ltd. with respective percentages of per cent and per cent respectively. However, among the private insurers, Reliance General Insurance Co. showed a maximum average claim ratio of per cent followed by IFFCO-Tokio and Royal Sundaram with the respective percentages of per cent and per cent. Cholamandalam General Insurance Co., the private insurer showed the least average claim ratio of per cent followed by TATA-AIG with the ratio of per cent. The average claim ratio of all the public sector insurers is per cent and that of private insurers is per cent, which clearly indicates a huge difference between the public and private insurers' claim ratio. The standard deviation values of the public and private sector general insurance companies are 6.97 and which exhibit that public insurers are more consistent than the private insurers in paying claim to the customers. Year-wise analysis indicates that the average claim ratio of the public sector is the highest, i.e., per cent in the year followed by per cent in the year The private insurers' average claim ratio is also the highest in the year followed by the year A closer investigation of the product portfolio, reveals that it is mainly due to the fact that the private companies are concentrating more on the creamy business. In respect of loss making portfolio, such as motor business, they have avoided to enter these businesses to reduce their claim incurred ratio. Further investigation reveals that public sector insurance companies do not get much of their business reinsured in contrast to the private sector players, who get most of the business reinsured to reduce their claim incurred ratio. Mann- Whitney test further shows that there is significant difference between the claim ratio of the public and the private sector general insurance companies. 158

5 Mean Median S.D. Expense Ratio The ratio of expenses of management as percentage of gross direct premium reflects how much percentage of revenue is being utilised for expenses on management. This ratio is a pointer of the cost effectiveness and the productivity. Expenses of management are generally operating expenses which include employees remuneration and benefits, office and administrative expenses, etc. and a higher ratio reflects financial instability of the business because a decrease in revenue may result in losses, whereas lower ratio is an indicator of better operational performance. It becomes important to examine, how far the public sector general insurance companies have been in a position to reduce their operating costs, in the post-liberalization period.

6 Table 6.2 reports the results of insurer-wise expense of management ratio from the year to The table also reveals mean, median and standard deviation for each general insurance company over the study period and also for each year across the 12 companies. The results show that average expense of management ratio of the public sector general insurance companies is per cent, whereas that of the private sector companies is per cent which is higher by 1.81 per cent in the case of private sector general insurance companies during the period to However, the Mann-Whitney test results indicate that the gap in expense of management ratio of both the public and private sector companies is insignificant. Among the public sector insurers, United India has registered the highest expense of management ratio (38.45 per cent) followed by New India (35.82 per cent), Oriental (35.61 per cent) and National (33.41 per cent). Among the private sector insurers, Cholamandalam has exhibited the highest average expense ratio of per cent followed by HDFC CHUBB (61.61 per cent) and Tata-AIG per cent. However, Reliance has registered the least average expense of management ratio of per cent followed by ICICI Lombard with per cent. Year-wise results explain that the average expense ratio of the public sector companies during the year was per cent which increased to per cent in the year However, it came down to per cent during the year Among the private sector insurers, the average expense ratio in the year was per cent which reduced to per cent in the year So, it is evident from the table that in the initial years of reforms the private sector had to spend more on advertisements, commission and other expenses. But with the passage of time, these private sector general insurance companies took various cost effective measures which led to improve their operational performance. The standard deviation of expense of management ratio in the case of public sector companies is 4.79 per cent, whereas it is per cent in private sector companies. It is clear that there was wide variation in the expense ratio of the private sector general insurance companies during the period to

7 Combined Ratio This ratio reflects the combined effect of expenses of management and claim incurred. It is the most common measure of underwriting profitability. Financial analysts rely on it for comparing the profitability of insurance business of different companies and for comparing different lines of business. The companies use it for steering their business (Holzheu, 2006).

Sig. (2- tailed) Mann- Whitney Test Combined Ratio The insurer-wise combined ratio results for the period to have been exhibited in table 6.3. The table also reflects the mean, median and standard deviation for each general insurance company over the study period. The results reveal that the average combined ratio in the case of public sector general insurance companies during the period to is 161

8 per cent, whereas it is per cent in private sector insurance companies. It is evident that combined ratio of the public sector is higher by per cent than the private sector. This has been due to higher claim ratio of the public sector. Among the public insurers, United India exhibits the highest average combined ratio of per cent followed by National per cent, Oriental per cent and New India per cent. However, among the private insurers, Cholamandalam has exhibited the highest average combined ratio of per cent followed by HDFC CHUBB per cent, Royal Sundaram per cent, Tata AIG per cent, Reliance per cent, Bajaj Allianz per cent, IFFCO-Tokio per cent and ICICI Lombard per cent. Year-wise, the average combined ratio of the public sector in the year was per cent which increased to per cent in the year Again, it showed a decreasing trend and reached at per cent in the year The average combined ratio of the private sector general insurance companies in the year was per cent which reduced to per cent in the year Both the public and private sector general insurance companies showed a standard deviation of 8.89 per cent and per cent respectively. It indicates that the variation in the combined ratio of the private sector general insurance companies is higher. The results of Mann-Whitney test also indicate that the combined ratio of the public sector is significantly higher than that of the private sector general insurance companies. Underwriting Results Ratio The underwriting results ratio of a general insurance company is depicted by taking net written premium minus increase in the unexpired risk reserve minus expense of management minus claim incurred minus commission. The underwriting results indicate the performance of an insurance company from core insurance business. The underwriting results ratio is calculated by dividing underwriting results to net written premium. 162

Table 6.4 Underwriting Results Ratio of General Insurance Companies during the Post-reform Period (Percentage) Name of the Company National New India Oriental United India Mean Median S.D Royal Sundaram Reliance IFFCO-Tokio TATA AIG Bajaj Allianz ICICI Lombard Cholamandalam HDFC CHUBB Mean Median S.D Source: Compiled from IRDA Annual Reports from to Test of Significance Test Ratio Z-value Asymp. Sig. (2-tailed) Mann- Whitney Test Underwriting Results Ratio The underwriting results to net written premium ratio of both the public and private sector general insurance companies from to have been presented in table 6.4. It is clear that the average underwriting results ratio of the public sector general insurance companies is per cent and that of private sector companies is per cent. Thus, the underwriting losses of public sector companies are higher as compared to the private sector companies. Among the public sector companies, United India has registered the highest average underwriting losses of per cent followed by National per cent, Oriental per cent and New India per cent which means that all the public sector general insurance companies have shown huge 163

10 underwriting losses. However, among the private insurers, Cholamandalam has shown the highest average underwriting loss of per cent followed by HDFC CHUBB per cent, Reliance per cent, Royal Sundaram per cent, ICICI Lombard per cent, Tata AIG per cent and IFFCO-Tokio per cent of all the private insurers, only Bajaj Allianz earned average underwriting profits of 1.53 per cent. Year-wise, the public insurers showed an increasing trend during the period to , when average underwriting losses increased from per cent to per cent and again reduced to per cent in the year However, the private insurers showed decreasing trend except during the year The average underwriting losses of the private sector companies during the year were per cent which reduced to just per cent in the year and again increased to per cent in the year All the private insurers except Cholamandalam and HDFC CHUBB, exhibited underwriting losses lower than the public sector insurers. The standard deviation of the underwriting results ratio of the public insurers is 7.79 per cent, whereas that of the private insurers is per cent which clearly indicates that the variation in underwriting results of the private sector general insurance companies is higher. The Mann-Whitney test also reveals that there is a significant gap between underwriting losses of the public and private insurers. The main reason for higher underwriting losses of the public insurers is mainly ascribed to low reinsurance of their business and higher expenses of management and incurred claim. Their excessive management expenses have been higher due to massive strength of manpower. On the other hand, private companies get most of their business reinsured to reduce their losses from underwriting. Moreover, they have minimum staff strength and advanced technology at their disposal. So, public sector general insurance companies need to reduce the staff strength and use more advanced technology to compete with the private sector. The general insurance business in India has been detariffed with effect from 1st January, 2007; and even companies are allowed to change the policy wordings with effect from 1st April, Now, it is the 164

11 Mean Median S.D. right time for the public sector to revisit their loss making portfolios to improve upon their underwriting results. Investment Income Ratio Investment performance discloses the effectiveness and efficiency of investment decisions. As such, investment performance becomes critical to the financial solidity of an insurer. The investment performance is negatively correlated to insolvency rate (Chen and Wong, 2004). It is also a function of asset allocation and asset management as well as asset leverage. The investment income ratio is determined by investment income to net written premium. Table 6.5 Investment Income Ratio of General Insurance Companies during the Post-reform Period (Percentage) Name of the Company National New India Oriental United India Mean Median S.D Royal Sundaram Reliance IFFCO-Tokio TATA AIG Bajaj Allianz ICICI Lombard Cholamandalam HDFC CHUBB Mean Median S.D Source: IRDA Annual Reports from to Test of Significance Test Ratio Z-value Asymp. Sig. (2- tailed) Mann- Whitney Test Investment Income Ratio

12 Table 6.5 highlights the investment income to net written premium ratio of the public and private insurers for the period to The results indicate that the average investment income ratios of the public and private insurers are per cent and per cent respectively. Thus, it is per cent higher in the case of public sector insurers. Among the public sector insurers, United India exhibits the highest average investment income ratio of per cent followed by Oriental per cent, New India per cent and National per cent. However, among the private insurers, Cholamandalam exhibits the highest average investment income ratio of per cent followed by Reliance per cent, ICICI Lombard per cent, HDFC CHUBB per cent, IFFCO-Tokio per cent, Tata AIG per cent, and Royal Sundaram per cent. Bajaj Allianz has shown the least average investment income ratio. There is a wide gap in the investment income ratio of Cholamandalam and Reliance with other private sector insurance companies and this is mainly due to the investment income ratio during the first two years. Year-wise, the average investment income of all the public insurers in the year was per cent which showed an increasing trend up to when it rose to per cent. Then it showed a downward trend and became per cent in the year However, the private insurers' average investment income ratio continuously exhibited a downward trend and during the period to , it decreased from per cent to 9.55 per cent. The standard deviation of investment income ratio of the public insurers is per cent, while it is per cent in the case of private insurers which explains more variation in the investment income of the private insurers. It brings out that the private sector has accumulated fewer underwriting losses and generated less investment income and having been in business much longer, the public sector companies have considerable investment portfolios and have benefited greatly from the strong performance of the Indian economy. The substantial investment portfolios of the public sector have compensated for their relatively weaker underwriting performance. 166

13 Mean Median S.D. The Mann-Whitney test also indicates that the gap in the investment income of public sector insurance companies is significantly greater than that of the private sector. Net Retention Ratio Net Retention ratio may be defined as net written premium divided by gross-direct premium. It is a measure of the companies ability to bear risks. Direct insurance companies are required to cede a minimum of 15% (down from 20% since April 2007) of their business to the national reinsurer, GIC. (Moody's ICRA Global, 2008). In general, the companies having a stronger capital base are able to retain more of their portfolios, whereas the companies, with relatively lower capitalization (and hence lower capacity to retain risks) have resorted to higher utilization of reinsurance.

14 Test of Significance Test Ratio Z-value Asymp. Sig. (2-tailed) Mann- Whitney Test Net Retention Ratio Table 6.6 presents the trends of net retention ratio of all the public and private sector general insurance companies from the years to The average net retention ratio of the public insurers during the period of study is per cent, whereas it is per cent in the case of private insurers. It is evident that the average net retention ratio of the public insurers is per cent higher than that of the private insurers. Among the public insurers, New India has exhibited the highest average net retention ratio of per cent followed by National with a percentage of per cent, United India has per cent and Oriental per cent. Among the private insurers, HDFC CHUBB has exhibited the highest average net retention ratio of per cent followed by Royal Sundaram with a percentage of per cent, Tata AIG per cent, Bajaj Allianz per cent, ICICI Lombard per cent, IFFCO-Tokio per cent, Cholamandalam per cent and Reliance per cent. The Year-wise trends indicate that, the public insurers have reported on upward trend. Their average net retention ratio in the year was per cent which increased to per cent in the year Similarly, the private insurers also reported an upward trend. Their average net retention ratio in the year was per cent which increased to per cent in the year The standard deviation values of the net retention ratio of both the public and private insurers are 3.45 per cent and per cent respectively, indicating higher consistency of the public insurers regarding net retention. As is evident from the above analysis, the investment income offset the effect of underwriting loss and contributing to the profitability of insurers. The main reason for greater investment income of the public sector companies is their high net retention which enables them to use more premiums in investments. So, in order to increase their investment income and profitability, the private sector companies need to enhance their net retention. 168

15 Mean Median S.D. In general, the strong capital base of public sector companies has enabled them to retain more of their portfolio, which the private insurers with a weak capitalization (and hence lower capacity to retain risks) have resorted to higher utilization of reinsurance resulting in lower net retention. The Mann- Whitney test indicates that there is a significant gap between the net retention ratio of public and private insurers. Operating Ratio Operating Ratio may be defined as profit before tax divided by net written premium. Table 6.7 Operating Ratio of General Insurance Companies during the Post-reform Period (Percentage) Name of the Company National New India Oriental United India Mean Median S.D Royal Sundaram Reliance IFFCO-Tokio TATA AIG Bajaj Allianz ICICI Lombard Cholamandalam HDFC CHUBB Mean Median S.D Source: IRDA Annual Reports from to Test of Significance Test Ratio Z-value Asymp. Sig. (2- tailed) Mann- Whitney Test Operating Ratio

16 Table 6.7 carried the data regarding operating ratio (profit before tax to NWP) of both the public and private insurers for the period to It is evident from the table that the average operating ratios of the public and private sector general insurance companies for the period are per cent and 4.05 per cent respectively which indicates that the public sector insurers average operating ratio is per cent higher than that of the private sector insurers. Among the public sector insurers, New India achieved the highest average operating ratio of per cent followed by United India, Oriental and National with the respective percentages of per cent, per cent and 5.60 per cent. All the public insurers have earned operating profit during all the years under study except National Insurance Company which suffered operating loss of 2.22 per cent in the year Among the private insurers, Reliance has exhibited the highest average operating ratio of per cent followed by ICICI Lombard, Bajaj Allianz, IFFCO-Tokio, Tata AIG and Royal Sundaram with the respective percentages of per cent, per cent, 8.01 per cent, 7.41 per cent and 2.48 per cent. The other private insurers suffered average operating losses, whereas HDFC CHUBB showed the highest negative average operating ratio of per cent followed by Cholamandalam with a percentage of per cent. So, among the private insurers, Reliance, ICICI Lombard and Bajaj Allianz have exhibited better operating ratios as compared to other private insurers. Year-wise analysis provides that the average operating ratio of the public insurers has shown an upward trend during the period to when it increased from 8.73 per cent to per cent, and again it came down to per cent in the year , and further in it became per cent. The private insurers in the year showed a negative average operating ratio of per cent. However, from the year onwards it registered a positive operating ratio with no consistent trend, i.e., it showed an upward trend up to and again showed a downward trend from to Overall, the public sector companies earned a higher average operating profit as compared to their counter-parts. The Mann-Whitney test also indicates that 170

17 Mean Median S.D. there is a significant gap between the operating ratios of the public and private insurers. Net Earning Ratio The Net Earning Ratio shows how profitable the insurance business is. This ratio reflects the summary of all activities during the period under review. The Net Earning Ratio has been calculated by dividing profit after tax to net written premium. Table 6.8 explains that the net earning ratios of the public sector General Insurance Companies have improved during the period under study. Table 6.8 Net Earning Ratio of General Insurance Companies during the Postreform Period (Percentage) Name of the Company National New India Oriental United India Mean Median S.D Royal Sundaram Reliance IFFCO-Tokio TATA AIG Bajaj Allianz ICICI Lombard Cholamandalam HDFC CHUBB Mean Median S.D Source: IRDA Annual Reports from to Test of Significance Test Ratio Z-value Asymp.

18 Table 6.8 highlights the trends of net earning ratio (profit after tax to NWP) of the public and private sector general insurance companies for the period to The average net earning ratios of both the public and the private insurers for the period are per cent and 2.17 per cent respectively which exhibits that the net earning ratio of public insurers is higher by per cent than that of the private insurers. Among the public sector insurers, New India has earned the highest average net earning ratio of per cent followed by United India, Oriental and National with the respective percentages of per cent, per cent, and 4.95 per cent. All the public insurers have shown operating profit during all the years under study except National Insurance Company which suffered a loss of per cent in the year Among the private insurers, Reliance has earned the highest average net earning ratio of per cent followed by ICICI Lombard, Bajaj Allianz, IFFCO-Tokio, Tata AIG and Royal Sundaram with the respective percentages of 10.76, 7.23, 5.21, 2.49 and Among the other private insurers, HDFC CHUBB suffered the highest average loss of per cent followed by Cholamandalam with a loss of per cent. Year-wise analysis provides that the public insurers have registered the highest average net earning ratios of per cent and per cent during the last two years, i.e., and respectively. However, no clear trend in the case of the public insurers could be observed. In the case of private insurers, the average net earning ratio is the highest, i.e., 6.25 per cent during the year followed by the ratios both of 5.10 per cent, and 4.62 per cent during the years and respectively. The standard deviation values of both the public and private sector insurers also indicate that there is greater consistency in the net earning ratio of public insurers as compared to private insurers. The results of Mann- Whitney test also indicate that there is a significant gap between the net earning ratio of the public and private insurers. 172

19 Mean Median S.D. Return on Equity Ratio: Return on Equity Ratio indicates how well the resources of the owners have been used (Anthony and Reece, 1995). It measures the return accruing to owners' capital. It is computed by dividing profit after tax to Net worth. Table 6.9 shows the return accruing to owners' capital in the General Insurance companies under study. Table 6.9 Return on Equity Ratio of General Insurance Companies during the Post-reform Period (Percentage) Name of the Company National New India Oriental United India Mean Median S.D Royal Sundaram Reliance IFFCO-Tokio TATA AIG Bajaj Allianz ICICI Lombard Cholamandalam HDFC CHUBB Mean Median S.D Source: IRDA Annual Reports from to Test of Significance Test Ratio Z-value Asymp. Sig. (2-tailed) Mann- Whitney Test Return on Equity Ratio The trend on return on equity of both the public and private sector general insurance companies for the period to has been shown in table 6.9. The analysis provides that the average return on equity of 173

20 the public sector insurers is per cent, and that of private sector insurers is 5.36 per cent which means the public sector insurers earn 9.53 per cent higher average return on equity than the private insurers. Among the public sector insurers, United India has earned the highest average return on equity of per cent followed by Oriental, New India and National with the respective percentage of 16.89, and per cent. All the public sector insurers have shown a positive return on equity during all the years except National Insurance Company which showed a negative return on equity in the year of per cent. Among the private sector insurers, Bajaj Allianz achieved the highest average return on equity of per cent followed by ICICI Lombard (11.37 per cent), IFFCO-Tokio (7.29 per cent), Tata AIG (5.63 per cent), Royal Sundaram (5.03 per cent), and Reliance (1.57 per cent). HDFC CHUBB suffered a loss and showed a negative average return on equity of per cent. Year-wise analysis provides that public sector insurers' average return on equity was the highest in the year which is per cent followed by the percentages of per cent, per cent and per cent which appeared during the years , and respectively. In the case of the private insurers, the average return on equity is the highest, i.e., 8.90 per cent in the year followed by 8.37 per cent, 7.74 per cent, 5.21 per cent which appeared during the years , , and respectively. The Mann-Whitney test also indicates that there is a significant gap between the return on equity of the public and private insurers. The return on equity of the public insurers is significantly higher than that of the private insurers. Therefore, the study rejected the hypothesis that the profitability of the private insurers is significantly higher than that of the public insurers. On the basis of above analysis, it can be concluded that the private sector General Insurance companies have shown better efficiency in terms of claim incurred and combined ratio which resulted into lower underwriting losses. A closer investigation of the product portfolio, through their annual reports, reveals that it is mainly ascribed to the fact that the private companies 174

21 are concentrating more on the creamy business. In respect of loss making portfolio, such as motor business, they have avoided to enter this business to reduce their claim incurred ratio. Further investigation reveals that public sector insurance companies do not get much of their business reinsured in contrast to the private sector players, who get most of the business reinsured to reduce their claim incurred ratio. But the higher investment return of the public sector offsets their underwriting losses and resulted into their better operating, net earning and returns on equity ratios. The main reason for higher investment income of the public sector companies is their higher net retention which enables these companies to use more premium in investment. So, in order to increase the investment income and profitability, the private sector companies need to increase their net retention. In general, the strong capital base of public sector companies has enabled them to retain more of their portfolio, and private insurers with lower capitalization (and hence lower capacity to retain risks) have resorted to higher utilization of reinsurance resulted in lower net retention. It has been found that the underwriting results and investment results are negatively correlated. Good investment returns allow the public sector insurers to post losses on underwriting without risking overall losses. But the prospects for a rapid improvement in investment return are not certain. Equity markets are currently weak, volatile and uncertain. So, due to uncertain prospects of investment returns, the public sector general insurance companies must focus on underwriting results to achieve greater profitability. On the other hand, the private sector must bring more capital to improve net retention, increase risk bearing capacity which resulted into their increase in business and investment return. 6.4 Multivariate Profitability Analysis of the General Insurance Companies in the Post-reform Period Correlation analysis involves measuring the magnitude and direction of the relationship between two or more variables. Interdependence among variables is a common characteristic of most multivariate techniques and correlation matrix is a table used to display correlation coefficients between 175

22 these variables. Matrices form the basis for computation and understanding of the nature of relationships in multiple regressions, discriminant analysis, factor analysis, and many other similar techniques. One sample t-test is used as a parametric tool for testing the significance of correlation coefficient. The study aimed at identifying the most important independent variable (s) which have higher significant association with the dependent variable. The degree of association, i.e., strength and direction of correlation coefficients, between the selected variables and public sector insurers' profitability is studied for both the public and private sector companies during the post-reform period, and the correlation matrices are given in Tables 6.10 and 6.11 respectively.

Few independent variables have also significant correlation with one another during the post-reform period, such as expense of management ratio and claim ratio have a significant negative 176

23 correlation with underwriting results and their coefficients are and respectively. Underwriting results have significant negative correlation with investment income ratio due to this higher underwriting loss is offset by higher investment income ratio of the public sector general insurance companies resulted into higher profitability.

Underwriting results have significant positive correlation with return on equity and the coefficient is Other independent variables, namely, claim ratio, investment income ratio & growth rate have not significant correlation with return on equity. Few independent variables have also significant correlation with one another, such as claim ratio has significant negative correlation with expense of management ratio and the coefficient is Expense of management has a significant negative correlation with 177
