Equity multiplier = total assets/total equity
Times interest earned=EBIT/interest
Cash coverage ratio=(EBIT+ depreciation)/interest
Common-Size Balance sheets(共同比报表)：用百分比代替具体金额的报表
Common-SizeIncomesheets(共同比损益表)：同上

短期偿债能力比率
Current ratio = current assets / current liabilities（流动比率）
Return on assets (ROA)= net income/total assets
Return on equity(ROE)= net income/total equity
ROE=(net income/sales)*(sales/assets)*(assets/equity)(杜邦等式)

book value per share=bookvalue of equity/shares
内部增长率和可持续增长率
Dividend payout ratio=cash dividends/net income（股利支付率）
Retention ratio=addition to retained earnings/net income=1-Dividend payout ratio
cash flow to creditors=interesting paid – net new borrowing
cash flow to stockholders=dividends paid – net new equity raised
第三章：与财务报表相关的工作
Standardized financial statements(标准化的财务报表)
Quick ratio = (current assets - inventory)/current liabilities(速动比率)
Cashratio = cash/current liabilities
长期偿债能力比率
Totaldebt ratio = (total assets – total equity)/total assets
Earnings per share = net income/ total shares outstanding
Dividends per share = total dividends/ total shares outstanding
Average versus Marginal Tax Rates(平均税率和边际税率)
(盈利留存率b)
Internal growth rate=(ROA*b)/(1-ROA*b) (内部增长率)
Sustainable growth rate==(ROE*b)/(1-ROE*b) (可持续增长率)
ROE=profit margin* total assets turnover * equity multiplier

第二章：财务报表、税收和现金表
The balance sheet(资产负债表)
Assets=Liabilities + shareholders’ equity
Assets:current assets; fixed assets
Current assets: cash; accounts receivable; inventory
The income statement(损益表)
Revenues – expenses = income
EBIT= net sales – cost of goods sold – depreciation
Taxable income = EBIT – interest paid
Net income = taxable income – taxes=dividends + addition to retained earnings
operating cash flow=EBIT +depreciation-taxes
net investment in fixed asset=ending net fixed assets-beginning net fixed assets + depreciation
change in NWC=ending NWC – beginning NWC
Cash flow from assets = cash flow to creditors + cash flow to stockholders
Cash flow from assets = operating cash flow-net investment in fixed assets-change in NWC
Days’ sales in receivable =365 day/receivable turnover
Total asset turnover = sales/total assets
Capitalintensity=total assets/sales
获利能力比率
Profit margin = net income/sales
Averagetax rate=total taxes paid/ total taxable income
Marginal tax rate: the amount of taxpayable on the next dollar earned
Cash flow(现金流量)
NWC=currentassets-currentliabilities
pv=c*(1-(1/(1+r)t))/r
年金（区别普通年金和预付年金付款时间）
永续年金 pv=c/r
EAR(有效年利率)=(1+quoted rate（名义利率）/m)m-1
EAR(有效年利率)=(1+APR（贷款的年百分率）/12)12-1
贷款类型：
Pure discount loans(纯贴现贷款)
