Using the WACC methodology to improve the assessment of projects in the french farming industry. Empirical evidences from farm's results of Isère( Télécharger le fichier original )par Anaël BIBARD Grenoble Graduate School of Business - MBA 2012 |
ConclusionThe WACC methodology tested in this research presents real limitations due to its underlying theories based on the market efficiency. This assumption holds only for the listed companies, introducing a bias in the calculation presented in this paper. However, the results obtained are consistent with the initial expectations regarding the relationship between leverage and financial performance or financial distress. Therefore, consultants should take more consideration for this methodology and use it in their feasibility studies. The other achievement of this paper concerns the discount rates actually used by practitioners. All signs clearly indicate that many of them use abnormally low actualization rates, ranging from 2.5 to 4.5%. The impact of these low actualization rates in valuation methods, such as the profitability method, can be really important. The NPV of a farm can be over-estimated by two to four using such discount factors! Some consultants use more appropriate rates, but it is far from being a generality according to the results of the survey. Then, it appears clearly that leverage has a positive impact on the financial performance of the farms of Isère. These expected results confirm that the WACC methodology should hold in the context of small and medium farming business. Therefore, consultants should consider the capital structure of the farms into consideration not only to avoid the risk of financial distress, but also to look for the optimal leverage, which appears to range between 40 and 60%. From the results presented in this paper, the 60-80% leverage group presented really good performances, but also more variability. Moreover, the bankruptcy risk was not studied because a sample of farms studied had to be constant. Therefore, it is safer to consider that the optimal debt level lies in the group 40-60%, may be closer to 60% regarding the good performance of the 60-80% group, particularly for the dairy specialization. Finally, the consultants of the CERFRANCE Isère do not need to wait for other researches on the field to modify their methods. Main recommendation is to increase significantly their actualization rates. On the other side, it must be acknowledge that further researches on the topic are necessary to improve the methodology and determine more precisely the hypothesis that should be taken, regarding the risk premiums and the beta for example. The productivity constraints of the consultants working in the different CERFRANCE militate in favor of a partnership with the engineering schools specialized in agriculture. This partnership, already implemented in some schools, could be the starting point of others researches about the financial performances of farming businesses. BibliographyAgreste. (2011 b).

Appendix 6: ROE by year One-Way ANOVA - ROE by ANNEE Dependent variable: ROE Factor: ANNEE Number of observations: 2840 Number of levels: 5 The StatAdvisor This procedure performs a one-way analysis of variance for ROE. It constructs various tests and graphs to compare the mean values of ROE for the 5 different levels of ANNEE. The F-test in the ANOVA table will test whether there are any significant differences amongst the means. If there are, the Multiple Range Tests will tell you which means are significantly different from which others. If you are worried about the presence of outliers, choose the Kruskal-Wallis Test which compares medians instead of means. The various plots will help you judge the practical significance of the results, as well as allow you to look for possible violations of the assumptions underlying the analysis of variance. Summary Statistics for ROE
The StatAdvisor 4 This table shows various statistics for ROE for each of the 5 levels of ANNEE. The one-way analysis of variance is 2006 2007 2008 2009 2010 primarily intended to compare the means of the different levels, listed here under the Average column. Select Means Plot ANNEE from the list of Graphical Options to display the means graphically. WARNING: The standardized skewness and/or kurtosis is outside the range of -2 to +2 for 5 levels of ANNEE. This indicates some significant nonnormality in the data, which violates the assumption that the data come from normal distributions. You may wish to transform the data or use the Kruskal-Wallis test to compare the medians instead of the means. ANOVA Table for ROE by ANNEE
The StatAdvisor The ANOVA table decomposes the variance of ROE into two components: a between-group component and a within-group component. The F-ratio, which in this case equals 4,23794, is a ratio of the between-group estimate to the within-group estimate. Since the P-value of the F-test is less than 0,05, there is a statistically significant difference between the mean ROE from one level of ANNEE to another at the 95,0% confidence level. To determine which means are significantly different from which others, select Multiple Range Tests from the list of Tabular Options. ANOVA for ROE 2 Table of Means for ROE by ANNEE with 90,0 percent LSD intervals 0,04
The StatAdvisor This table shows the mean ROE for each level of ANNEE. It also shows the standard error of each mean, which is a measure of its sampling variability. The standard error is formed by dividing the pooled standard deviation by the square root of the number of observations at each level. The table also displays an interval around each mean. The intervals currently displayed are based on Fisher's least significant difference (LSD) procedure. They are constructed in such a way that if two means are the same, their intervals will overlap 95,0% of the time. You can display the intervals graphically by selecting Means Plot from the list of Graphical Options. In the Multiple Range Tests, these intervals are used to determine which means are significantly different from which others. Multiple Range Tests for ROE by ANNEE Method: 90,0 percent LSD
* denotes a statistically significant difference. The StatAdvisor This table applies a multiple comparison procedure to determine which means are significantly different from which others. The bottom half of the output shows the estimated difference between each pair of means. An asterisk has been placed next to 6 pairs, indicating that these pairs show statistically significant differences at the 95,0% confidence level. At the top of the page, 2 homogenous groups are identified using columns of X's. Within each column, the levels containing X's form a group of means within which there are no statistically significant differences. The method currently being used to discriminate among the means is Fisher's least significant difference (LSD) procedure. With this method, there is a 5,0% risk of calling each pair of means significantly different when the actual difference equals 0. Variance Check
The StatAdvisor The statistic displayed in this table tests the null hypothesis that the standard deviations of ROE within each of the 5 levels of 4 ANNEE is the same. Of particular interest is the P-value. Since the P-value is greater than or equal to 0,05, there is not a statistically significant difference amongst the standard deviations at the 95,0% confidence level. The table also shows a comparison of the standard deviations for each pair of samples. P-Values below 0.05, of which there are 7, indicate a statistically significant difference between the two sigmas at the 5% significance level. Kruskal-Wallis Test for ROE by ANNEE
Test statistic = 57,0073 P-Value = 1,2328E-11 The StatAdvisor The Kruskal-Wallis test tests the null hypothesis that the medians of ROE within each of the 5 levels of ANNEE are the same. The data from all the levels is first combined and ranked from smallest to largest. The average rank is then computed for the data at each level. Since the P-value is less than 0,05, there is a statistically significant difference amongst the medians at the 95,0% confidence level. To determine which medians are significantly different from which others, select Box-and-Whisker Plot from the list of Graphical Options and select the median notch option. Mood's Median Test for ROE by ANNEE Total n = 2840 Grand median = 0,0583012 0,12
Test statistic = 46,0986 P-Value = 2,3492E-9 The StatAdvisor Mood's median test tests the hypothesis that the medians of all 5 samples are equal. It does so by counting the number of 0 observations in each sample on either side of the grand median, which equals 0,0583012. Since the P-value for the chi- 2006 2007 2008 2009 2010 square test is less than 0,1, the medians of the samples are significantly different at the 90,0% confidence level. Also ANNEE included (if available) are 90,0% confidence intervals for each median based on the order statistics of each sample. Appendix 7:ROA by year One-Way ANOVA - ROA by ANNEE Dependent variable: ROA Factor: ANNEE Number of observations: 2840 Number of levels: 5 The StatAdvisor This procedure performs a one-way analysis of variance for ROA. It constructs various tests and graphs to compare the mean values of ROA for the 5 different levels of ANNEE. The F-test in the ANOVA table will test whether there are any significant differences amongst the means. If there are, the Multiple Range Tests will tell you which means are significantly different from which others. If you are worried about the presence of outliers, choose the Kruskal-Wallis Test which compares medians instead of means. The various plots will help you judge the practical significance of the results, as well as allow you to look for possible violations of the assumptions underlying the analysis of variance. Summary Statistics for ROA
The StatAdvisor 21 This table shows various statistics for ROA for each of the 5 levels of ANNEE. The one-way analysis of variance is 2006 2007 2008 2009 2010 primarily intended to compare the means of the different levels, listed here under the Average column. Select Means Plot ANNEE from the list of Graphical Options to display the means graphically. WARNING: The standardized skewness and/or kurtosis is outside the range of -2 to +2 for 5 levels of ANNEE. This indicates some significant nonnormality in the data, which violates the assumption that the data come from normal distributions. You may wish to transform the data or use the Kruskal-Wallis test to compare the medians instead of the means. ANOVA Table for ROA by ANNEE
The StatAdvisor The ANOVA table decomposes the variance of ROA into two components: a between-group component and a within-group component. The F-ratio, which in this case equals 11,9622, is a ratio of the between-group estimate to the within-group estimate. Since the P-value of the F-test is less than 0,05, there is a statistically significant difference between the mean ROA from one level of ANNEE to another at the 95,0% confidence level. To determine which means are significantly different from which others, select Multiple Range Tests from the list of Tabular Options. ANOVA for ROA 0,2 0,8 1, Table of Means for ROA by ANNEE with 90,0 percent LSD intervals 0,03
The StatAdvisor This table shows the mean ROA for each level of ANNEE. It also shows the standard error of each mean, which is a measure of its sampling variability. The standard error is formed by dividing the pooled standard deviation by the square root of the number of observations at each level. The table also displays an interval around each mean. The intervals currently displayed are based on Fisher's least significant difference (LSD) procedure. They are constructed in such a way that if two means are the same, their intervals will overlap 95,0% of the time. You can display the intervals graphically by selecting Means Plot from the list of Graphical Options. In the Multiple Range Tests, these intervals are used to determine which means are significantly different from which others. Multiple Range Tests for ROA by ANNEE Method: 90,0 percent LSD
* denotes a statistically significant difference. The StatAdvisor This table applies a multiple comparison procedure to determine which means are significantly different from which others. The bottom half of the output shows the estimated difference between each pair of means. An asterisk has been placed next to 6 pairs, indicating that these pairs show statistically significant differences at the 95,0% confidence level. At the top of the page, 2 homogenous groups are identified using columns of X's. Within each column, the levels containing X's form a group of means within which there are no statistically significant differences. The method currently being used to discriminate among the means is Fisher's least significant difference (LSD) procedure. With this method, there is a 5,0% risk of calling each pair of means significantly different when the actual difference equals 0. Variance Check
The StatAdvisor The statistic displayed in this table tests the null hypothesis that the standard deviations of ROA within each of the 5 levels of 3 ANNEE is the same. Of particular interest is the P-value. Since the the P-value is less than 0,05, there is a statistically significant difference amongst the standard deviations at the 95,0% confidence level. This violates one of the important 2 assumptions underlying the analysis of variance and will invalidate most of the standard statistical tests. The table also shows a comparison of the standard deviations for each pair of samples. P-Values below 0.05, of which there are 9, indicate a statistically significant difference between the two sigmas at the 5% significance level. 0 Kruskal-Wallis Test for ROA by ANNEE
Test statistic = 73,6591 P-Value = 0 The StatAdvisor The Kruskal-Wallis test tests the null hypothesis that the medians of ROA within each of the 5 levels of ANNEE are the same. The data from all the levels is first combined and ranked from smallest to largest. The average rank is then computed for the data at each level. Since the P-value is less than 0,05, there is a statistically significant difference amongst the medians at the 95,0% confidence level. To determine which medians are significantly different from which others, select Box-and-Whisker Plot from the list of Graphical Options and select the median notch option. Mood's Median Test for ROA by ANNEE Total n = 2840 0001 Grand median = 0,034619 79
Test statistic = 58,6901 P-Value = 5,46618E-12 19 The StatAdvisor Mood's median test tests the hypothesis that the medians of all 5 samples are equal. It does so by counting the number of 1 observations in each sample on either side of the grand median, which equals 0,034619. Since the P-value for the chi-square 2006 2007 2008 2009 2010 test is less than 0,1, the medians of the samples are significantly different at the 90,0% confidence level. Also included (if ANNEE available) are 90,0% confidence intervals for each median based on the order statistics of each sample.
