 The provided sources outline an individual research project focused on analyzing factors influencing corporate social responsibility (CSR) reporting within semiconductor firms in 2016. The project utilizes financial data like Return on Assets (ROA) and firm size (SIZE), along with auditor information (Big4). Statistical tests, including t-tests, correlation analysis, and multivariate regression, are performed to examine the relationships between these variables and CSR disclosure. The project requires formulating hypotheses, interpreting regression results, and suggesting additional variables that could enhance the explanatory power of the model. The analysis concludes that ROA has a statistically significant, positive relationship with CSR disclosure.

Analysis of Semiconductor Firm Financial Data and CSR Reporting

1. Purpose:

The overall purpose of the project is to analyze the financial data of a sample of semiconductor firms for the fiscal year 2016 to explore relationships between financial performance, firm characteristics, and the decision to disclose Corporate Social Responsibility (CSR) information.

2. Data Description:

• The data is derived from the 10-K reports and financial data of a sample of semiconductor firms.
• Key variables included in the dataset are:
• CSR: Corporate Social Responsibility reporting (1 if disclosing; 0 otherwise).
• LAG: Number of days between 10-K filing date and fiscal year-end date.
• SIZE: Natural log of total assets.
• ROA: Return on Assets (earnings divided by total assets).
• Big4: Indicator for whether the auditor is a Big 4 firm (1 for Big4 auditor; 0 otherwise).
• Earnings ($): Net earnings for the fiscal year.
• Assets ($): Total assets of the firm.
• CIK Code: Company CIK identifier
• Auditor: Name of auditing firm.
• Auditor Key: Numerical ID for the audit firm.
• Year Ended Date: Fiscal year end date.
• Source Date: Date 10-k was filed.

3. Key Requirements and Findings:

The project involves several requirements, each designed to investigate different aspects of the data.

• Requirement 1 & 2: Hypothesis Testing for ROA and Size
• Objective: To determine if the means of ROA and Size are significantly different from zero.
• Hypotheses:
• Null Hypothesis (H0): The means of ROA and Size are equal to zero.
• Alternative Hypothesis (H1): The means of ROA and Size are different from zero.
• Findings:
• A t-test was conducted. The results are provided as:
• t-Test: Paired Two Sample for Means
• ROA Size
• Mean 0.002901 20.75939
• Variance 0.026429 2.76332
• Observations 64 64
• Pearson Correlation 0.483123
• Hypothesized Mean Difference 0
• df 63
• t Stat -104.424
• P(T<=t) one-tail 1.31E-72
• t Critical one-tail 1.669402
• P(T<=t) two-tail 2.62E-72
• t Critical two-tail 1.998341
• Requirement 3: Correlation Analysis
• Objective: To identify the relationships between the key variables (CSR, LAG, SIZE, ROA, Big4).
• Findings:
• The correlation matrix revealed the following relationships (from pr2.pdf):
• CSR LAG SIZE ROA Big4
• CSR 1
• LAG -0.26411 1
• SIZE 0.247621 -0.4275 1
• ROA 0.483777 -0.35531 0.483123 1
• Big4 0.162459 -0.15962 0.507085 0.230136 1
• CSR and LAG: Negative correlation (-0.26411) suggesting that firms with higher CSR scores tend to have shorter lag times between fiscal year-end and 10-K filing.
• CSR and SIZE: Modest positive correlation (0.247621) suggesting a possible link between firm size and CSR.
• CSR and ROA: Weak positive correlation (0.483777) suggesting that higher CSR is correlated with better ROA.
• CSR and Big4: Positive correlation (0.162459) suggesting a possible link between Big 4 audit firms and CSR.
• SIZE and ROA: Positive correlation (0.483123), suggesting that larger firms might have higher ROA.
• SIZE and Big4: Positive correlation (0.507085), indicating larger firms are more likely to be audited by Big 4 firms.
• The analysis (from pr3.pdf) suggests: "SIZE and Big4 are most positive then its CSR and ROA, then slightly less SIZE and ROA, which means big in size firms have more have higher chance to get audited by Big4, better ROA means higher CSR and higher ROA represents big size of firm."
• Requirement 4 & 5: Multivariate Regression Analysis
• Objective: To examine if the management decision to disclose CSR is a function of ROA, SIZE, and Big4.
• Model: CSR = A0 + A1(ROA) + A2(SIZE) + A3(Big4) + e
• Findings:Regression results are as follows:

• Statistical Significance:SIZE: Not statistically significant (P-value = 0.932157).
• ROA: Statistically significant (P-value = 0.000476).
• Big4: Not statistically significant (P-value = 0.652745).
• Explanatory Power (R-squared): 0.236893. The model explains approximately 23.69% of the variance in CSR.
• The regression analysis suggests that ROA has a statistically significant, positive relationship with CSR disclosure, while SIZE and Big4 do not show statistically significant relationships.
• Requirement 6: Additional Variables for the Model
• Two potential variables to add to the model are:
• Industry Type: To account for varying industry-specific pressures regarding CSR.
• Leverage Ratio: A company's debt levels could influence its CSR engagement.

4. Key Insights and Implications:

• ROA appears to be a significant driver of CSR disclosure among the semiconductor firms in the sample. Higher profitability (as measured by ROA) is associated with a greater likelihood of CSR reporting.
• Firm size (SIZE) and the use of a Big 4 auditor (Big4) do not appear to be statistically significant predictors of CSR disclosure in this model.
• The explanatory power of the model (R-squared = 0.2369) suggests that other factors beyond ROA, SIZE, and Big4 likely influence a company's decision to disclose CSR information.
• The findings suggest that financial performance plays a role in driving CSR initiatives and transparency in the semiconductor industry.

5. Conclusion

The analysis, explains hypothesis, exercising t-test, finding correlation, running multivariate regression to examine management decision to disclose CSR is a function of ROA, SIZE, BIG4, it helps determine if adding more variables may occur further discussion and deduce new theory to potentially improve reasoning & conclusion with possible variables Industry Type and Leverage Ratio to the model. These variables could capture broader influences that might explain more of the variance in CSR.
