There are four techniques, which are used to analyse the finacial statements contained in accounts .What are they?

1)Trend Analysis-It helps a firm's financial manager determine how the firm is likely to perform over time. Trend analysis is based on historical data from the firm's financial statements and forecasted data.

2) Common Size financial statement analysis-It Includes analyzing the balance sheet and income statement using percentages. All income statement line items are stated as a percentage of sales. All balance sheet line items are stated as a percentage of total assets

3) Percentage Change financial statement-In this, you calculate growth rates for all income statement items and balance sheet accounts relative to a base year. It will actually help you see how different income statement items and balance sheet accounts grew or declined relative to grows or declines in sales and total assets.

4) Benchmarking- It involves comparing a company to other companies in the same industry in order to see how a company is doing financially as compared to the industry. This type of analysis is very helpful to the financial manager as it helps him/her to see if any financial adjustments are needed to be made.

Thanks for this important question, you can refer to the following link (https://en.wikipedia.org/wiki/Financial_statement_analysis) where it's minsioned clearly and the simple answer is: Financial statement analysis is a method or process involving specific techniques for evaluating risks, performance, financial health, and future prospects of an organization.

Overview of Financial Statement Analysis

Financial statement analysis involves the identification of the following items for a company's financial statements over a series of reporting periods:

• Trends. Create trend lines for key items in the financial statements over multiple time periods, to see how the company is performing. Typical trend lines are for revenues, the gross margin, net profits, cash, accounts receivable, and debt.
• Proportion analysis. An array of ratios are available for discerning the relationship between the size of various accounts in the financial statements. For example, you can calculate a company's quick ratio to estimate its ability to pay its immediate liabilities, or its debt to equity ratio to see if it has taken on too much debt. These analyses are frequently between the revenues and expenses listed on the income statement and the assets, liabilities, and equity accounts listed on the balance sheet.

Financial statement analysis is an exceptionally powerful tool for a variety of users of financial statements, each having different objectives in learning about the financial circumstances of the entity.

Users of Financial Statement Analysis

There are a number of users of financial statement analysis. They are:

• Creditors. Anyone who has lent funds to a company is interested in its ability to pay back the debt, and so will focus on various cash flow measures.
• Investors. Both current and prospective investors examine financial statements to learn about a company's ability to continue issuing dividends, or to generate cash flow, or to continue growing at its historical rate (depending upon their investment philisophies).
• Management. The company controller prepares an ongoing analysis of the company's financial results, particularly in relation to a number of operational metrics that are not seen by outside entities (such as the cost per delivery, cost per distribution channel, profit by product, and so forth).
• Regulatory authorities. If a company is publicly held, its financial statements are examined by the Securities and Exchange Commission (if the company files in the United States) to see if its statements conform to the various accounting standards and the rules of the SEC.

Methods of Financial Statement Analysis

There are two key methods for analyzing financial statements. The first method is the use of horizontal and vertical analysis. Horizontal analysis is the comparison of financial information over a series of reporting periods, while vertical analysis is the proportional analysis of a financial statement, where each line item on a financial statement is listed as a percentage of another item. Typically, this means that every line item on an income statement is stated as a percentage of gross sales, while every line item on a balance sheet is stated as a percentage of total assets. Thus, horizontal analysis is the review of the results of multiple time periods, whiile vertical analysis is the review of the proportion of accounts to each other within a single period. The following links will direct you to more information about horizontal and vertical analyis:

The second method for analyzing financial statements is the use of many kinds of ratios. You use ratios to calculate the relative size of one number in relation to another. After you calculate a ratio, you can then compare it to the same ratio calculated for a prior period, or that is based on an industry average, to see if the company is performing in accordance with expectations. In a typical financial statement analysis, most ratios will be within expectations, while a small number will flag potential problems that will attract the attention of the reviewer.

There are several general categories of ratios, each designed to examine a different aspect of a company's performance. The general groups of ratios are:

1. Liquidity ratios. This is the most fundamentally important set of ratios, because they measure the ability of a company to remain in business. Click the following links for a thorough review of each ratio.
   • Cash coverage ratio. Shows the amount of cash available to pay interest.
   • Current ratio. Measures the amount of liquidity available to pay for current liabilities.
   • Quick ratio. The same as the current ratio, but does not include inventory.
   • Liquidity index. Measures the amount of time required to convert assets into cash.
2. Activity ratios. These ratios are a strong indicator of the quality of management, since they reveal how well management is utilizing company resources. Click the following links for a thorough review of each ratio.
   • Accounts payable turnover ratio. Measures the speed with which a company pays its suppliers.
   • Accounts receivable turnover ratio. Measures a company's ability to collect accounts receivable.
   • Fixed asset turnover ratio. Measures a company's ability to generate sales from a certain base of fixed assets.
   • Inventory turnover ratio. Measures the amount of inventory needed to support a given level of sales.
   • Sales to working capital ratio. Shows the amount of working capital required to support a given amount of sales.
   • Working capital turnover ratio. Measures a company's ability to generate sales from a certain base of working capital.
3. Leverage ratios. These ratios reveal the extent to which a company is relying upon debt to fund its operations, and its ability to pay back the debt. Click the following links for a thorough review of each ratio.
   • Debt to equity ratio. Shows the extent to which management is willing to fund operations with debt, rather than equity.
   • Debt service coverage ratio. Reveals the ability of a company to pay its debt obligations.
   • Fixed charge coverage. Shows the ability of a company to pay for its fixed costs.
4. Profitability ratios. These ratios measure how well a company performs in generating a profit. Click the following links for a thorough review of each ratio.
   • Breakeven point. Reveals the sales level at which a company breaks even.
   • Contribution margin ratio. Shows the profits left after variable costs are subtracted from sales.
   • Gross profit ratio. Shows revenues minus the cost of goods sold, as a proportion of sales.
   • Margin of safety. Calculates the amount by which sales must drop before a company reaches its breakeven point.
   • Net profit ratio. Calculates the amount of profit after taxes and all expenses have been deducted from net sales.
   • Return on equity. Shows company profit as a percentage of equity.
   • Return on net assets. Shows company profits as a percentage of fixed assets and working capital.
   • Return on operating assets. Shows company profit as percentage of assets utilized.

Problems with Financial Statement Analysis

While financial statement analysis is an excellent tool, there are several issues to be aware of that can interfere with your interpretation of the analysis results. These issues are:

• Comparability between periods. The company preparing the financial statements may have changed the accounts in which it stores financial information, so that results may differ from period to period. For example, an expense may appear in the cost of goods sold in one period, and in administrative expenses in another period.
• Comparability between companies. An analyst frequently compares the financial ratios of different companies in order to see how they match up against each other. However, each company may aggregate financial information differently, so that the results of their ratios are not really comparable. This can lead an analyst to draw incorrect conclusions about the results of a company in comparison to its competitors.
• Operational information. Financial analysis only reviews a company's financial information, not its operational information, so you cannot see a variety of key indicators of future performance, such as the size of the order backlog, or changes in warranty claims. Thus, financial analysis only presents part of the total picture.
