Ratios
Purpose of Ratios:
Assess features of a firm: profitability, liquidity, and risk.
Highlight sources of competitive advantages.
Identify potential trouble spots.
Comparison Methods:
Ratios must be compared to benchmarks, such as a control group.
Time Series Analysis: Compare the same firm at different points in time.
Cross-Sectional Analysis: Compare the firm to other firms in the industry.
Using Ratios
Importance of Benchmark:
A major change within a firm can distort time-series analysis.
Differences in business strategy, capital structure, or business segments can distort cross-sectional analysis.
Accounting method differences can also create distortions.
Misusing Ratios
Contextual Usage:
Ratios should be used in a contextual sense; a change in a ratio is not always indicative of good or bad performance.
Ratios guide informed questioning rather than providing definite answers.
Standard Definitions:
Ratios have multiple definitions; no standardized GAAP compliance constrains their definitions.
They are used for analysis, not reporting, and considered metadata from financial documents.
Manipulation Potential:
Managerial actions can manipulate ratios.
Monitoring behavior can lead to unintended consequences and incentives.
Return on Equity (ROE)
Definition:
ROE is calculated as the ratio of net income to average shareholders’ equity:
Formula: ROE = Net Income / Average Shareholders’ Equity.
Average is considered between beginning and end balances on the balance sheet.
Drivers of ROE
Primary Drivers:
Operating Performance: Efficiency in utilizing assets to generate profits.
Financial Leverage: The extent of debt management to increase asset availability against shareholder investment.
Return on Assets (ROA)
Measurement:
ROA measures operating performance:
Formula: ROA = Net Income / Average Total Assets.
The numerator shows the return generated for shareholders; the denominator shows resources used to generate this return.
Financial Leverage (FLR)
Definition:
FLR is the ratio of average assets to average shareholders’ equity:
Formula: FLR = Average Assets / Average Shareholders’ Equity.
Multiple leverage ratios exist (e.g., debt-to-equity).
Decomposing ROE
Formula:
ROE = ROA × FLR
Shows the connection between return on equity, return on assets, and financial leverage.
Example Calculation
Scenario:
A company raises $100 from shareholders and borrows $100 to acquire $200 in assets, generating $10 of net income.
Calculations:
ROE = 10/100 = 10%
ROA = 10/200 = 5%
FLR = 200/100 = 200%.
De-levering Net Income in ROA
Challenge:
ROA must account for capital structure; Net Income includes interest expenses.
Adjustment Required:
To de-lever Net Income:
Formula: Adjusted Net Income = Net Income + (Interest Expense × (1-Tax Rate)).
Effects of Leveraging - Example
Two Firms:
Firm A: Financed entirely with equity.
Firm B: Financed through equity and debt, both generating identical EBIT of $100.
Tax Shields and Interest Expenses
Concept:
Leveraged operations can yield higher total payments to shareholders due to tax deductions on interest.
Tax shield calculated as the product of interest expense and tax rate.
Optimal Capital Structure:
A strategy balancing tax shields against potential financial distress costs.
Decomposing the Return on Assets (ROA)
Key Drivers:
Return on Sales (ROS): Return generated from sales.
Formula: ROS = Net Income / Sales.
Asset Turnover Ratio (ATR): Efficiency in generating sales from assets.
Formula: ATR = Sales / Total Assets.
DuPont Decomposition
Breakdown of ROE:
ROE = ROA × FLR = (ROS × ATR) × FLR.
Retail Industry Examples
Low-End Retailers (e.g., MART stores):
High asset turnover despite low profitability due to volume play strategy.
High-End Retailers:
Constructed from expensive materials with high markups, resulting in lower asset turnover.
Plainview Technology Case Study
Background:
Manufactures iris scanning equipment; lost a major customer in 2009.
Management Response:
Increased automation, located closer to customers, diversified industries, and adopted advanced technology.
Outcome:
Experienced growth post-crisis.
Plainview Financial Statements Overview
Balance Sheet (Assets):
Analysis of assets from 2009-2011 illustrating growth in cash, accounts receivable, inventories, and net property, plant, and equipment.
Balance Sheet (Liabilities & Shareholders' Equity):
Evolution of liabilities and equity over the same period reflecting increased long-term debt and retained earnings.
Income Statement:
Highlights sales growth, gross profit, operating income, interest expenses, and net income from 2009 to 2011.
Common Size Financial Statements
Purpose:
Adjust for asymmetric growth across financial data.
Common Size Balance Sheet:
Values expressed as a fraction of total assets for comparative analysis.
Common Size Income Statement:
Values expressed as a fraction of total sales for trend identification.
