This document provides an overview of financial statement analysis techniques including horizontal analysis, vertical analysis, common-size statements, trend percentages, and ratio analysis. It includes examples of each technique applied to comparative financial statements for Clover Corporation and Sample Company. The horizontal analysis example calculates dollar and percentage changes in the balance sheet and income statement line items between years. The vertical analysis example expresses each financial statement line item as a percentage of a total. The trend percentages example calculates the percentage change in revenues, expenses, and net income from the base year.

Methods of
Financial Statement Analysis

8. 17-8
Horizontal Analysis
Using comparative financial
statements to calculate dollar
or percentage changes in a
financial statement item from
one period to the next

9. 17-9
Vertical Analysis
For a single financial
statement, each item
is expressed as a
percentage of a
significant total,
e.g., all income
statement items are
expressed as a
percentage of sales

10. 17-10
Common-Size Statements
Financial statements that show
only percentages and no
absolute dollar amounts

11. 17-11
Trend Percentages
Show changes over time in
given financial statement items
(can help evaluate financial
information of several years)

12. 17-12
Ratio Analysis
Expression of logical relationships
between items in a financial
statement of a single period
(e.g., percentage relationship
between revenue and net income)

13. 17-13
Horizontal Analysis Example
The management of Clover Company
provides you with comparative balance
sheets of the years ended December 31,
1999 and 1998. Management asks you to
prepare a horizontal analysis on the
information.
