c. Equity:
- Use the inverse normal function to find the 99th percentile value considering the standard deviation and confidence level.
- Multiply the percentile value by the standard deviation to get daily earnings at risk.
d. 9-day Value at Risk (VAR):
- Multiply the daily VAR by the square root of 9 (assuming a normal distribution).
e. Portfolio VAR:
- Use the individual VARs and correlation coefficients to calculate the portfolio VAR using a variance-covariance approach.
2. Contingent Liabilities
- Contingent assets and liabilities become actual assets and liabilities when the contingencies occur.
- To reflect the changes, add contingent assets to total assets and subtract contingent liabilities from total equity.
- Analyze the impact on the bank's capital ratios (e.g., capital adequacy ratio) due to the changes.
3. Automation Cost-Benefit Analysis
- Calculate the net present value (NPV) of the after-tax savings using the cost of capital as the discount rate.
- If the NPV is positive, automation is recommended due to cost savings outweighing the initial investment.
4. Risk-Based Capital Ratios
- Calculate risk-weighted assets by multiplying each asset class by its risk weight.
- Divide risk-weighted assets by Tier 1 capital, Tier 1 risk-based capital, total capital, and total assets to get the respective ratios.
- Compare the ratios to regulatory capital adequacy requirements to determine the capital category zone.
5. Securities Firm Ratios
a. Aggregate indebtedness to net capital ratio:
- Calculate the firm's net capital by subtracting subordinated liabilities from equity.
- Divide total liabilities by net capital.
b. Highly liquid assets to total liabilities ratio:
- Identify highly liquid assets (e.g., cash, marketable securities).
- Divide highly liquid assets by total liabilities.
c. Rule 15C 3-1 Compliance:
- Compare the calculated ratios to the regulatory limits set by Rule 15C 3-1 (limits may vary).
- If either ratio is above the limit, the firm is not in compliance.
Important Note:
It's crucial to consult financial regulations and refer to official sources for specific requirements and calculations.
