Please provide a detailed interpretation of L- U, Describe how to implement each of the following L - U, Conceptualize the formulas and in words provide proofs?

L: Price-Earnings Ratio

Price Earning= Market price per share/Basic earning per share

M.Operating Cycle

Operating cycle = Inventory period + Accounts Receivable period.

Operating cycle = (365 / (cost of goods sold / average inventory)) + (365 / (credit sales / average accounts receivable))

N.Debt/Equity

Debt/Equity Formula = Total Liabilities/ Shareholder's Equity

O.Times Interest Earned

Times Interest Earned = EBITDA / Interest Expense

Times Interest Earned = (Earnings before interest, taxes, depreciation and amortization) / Interest Expense

P.Fixed Asset Turnover

Fixed Asset Turnover = Net Sales / Average Fixed Asset

Fixed Asset Turnover = Net Sales/(( Beg. Fixed Asset + End. Fixed Asset)/2)

Q.Operating Profit Margin

Operating Profit Margin = Operating Income / Revenue

Operating Profit Margin = (Revenue - Cost) / Revenue

R.Return on Assets

Return on Assets = Net Income / Average Total Assets

Return on Assets = Net Income / ((Beg. Total Assets + End. Total Assets) / 2)

S. Equity Multiplier

Equity Multiplier = Total Assets / Total Shareholder's Equity

T.Return on Equity

Return on Equity = ( Net Income - Preferred Dividend) / Average Shareholder's Equity

Return on Equity = ( Net Income - Preferred Dividend) / ((Beg. Shareholder's Equity + End. Shareholder's Equity) / 2)

U.Industry AveragesIndustry Averages = Net Credit Sales / Average Accounts Receivable

Industry Averages = (Total Sales - Cash Sales) / ((Beg. Accounts Receivable + End. Accounts Receivable) / 2)
