Earnings per share
　　每股收益即每股盈利（EPS），又称每股税后利润、每股盈余，指税后利润与股本总数的比率。是普通股股东每持有一股所能享有的企业净利润或需承担的企业净亏损。每股收益通常被用来反映企业的经营成果，衡量普通股的获利水平及投资风险，是投资者等信息使用者据以评价企业盈利能力、预测企业成长潜力、进而做出相关经济决策的重要的财务指标之一。利润表中，第九条列示“基本每股收益”和“稀释每股收益”项目。高顿网校USCPA小编今天来给大家简单介绍每股收益的相关考点。
　　All public entities are required to present Earnings Per Share（EPS）on the face of the I/S.
　　参《企业会计准则第34号-每股收益》
　　Simple/Complex capital structure
　　If an entity has only common stock outstanding，then it has simple capital structure.The entity only need present basic EPS for “IDE” and “I” on the face of the I/S.
　　If an entity has securities that can potentially be converted to common stock，then it has complex capital structure.The entity need present both basic EPS and diluted EPS for “IDE” and “I” on the face of the I/S.
　　The key point of identify simple or complex capital structure is securities convertible to common stock.
　　The key result difference is diluted EPS.
　　Basic EPS=[NI available to C/S]/WACSO
　　NI available to C/S=NI–P/S dividend
　　P/S dividend=Dividend declared to P/S+Dividends in arrears
　　Weighted-Average number of Common Shares Outstanding（WACSO）is the mean of shares outstanding and assumed to be outstanding for EPS calculations.
　　发行在外普通股加权平均数（WACSO）=期初发行在外普通股股数+新发行普通股股数 X 已发行时间÷报告期间-当期回购普通股股数X已回购时间÷报告期间
　　考点1. Cumulative P/S 未宣告的股利（dividend in arrears）是否要在计算EPS时扣除？是的。必须扣除。因为在支付普通股股东股利之前，企业必须首先支付历年的dividend in arrears.
　　考点2. 如果三个Stock dividends / splits方案，除实施时间不同外（分别在3/31/X1，9/30/X1，1/2/X2 ），无任何区别。B/S date是12/31，报告签发日为2/25/X2.问三个方案下谁的EPS*5？一样大。
　　Stock dividends/splits before the F/S ISSUE DATE must be treated as though they occurred at the earliest beginning of the period in the report.
　　Complex capital structure–potentially dilutive securities type：
　　Convertible securities（convertible P/S or bonds）
　　Warrants and other options
　　Contracts that may be settled in cash or stock；and
　　Contingent shares
　　“Treasury stock” Dilutive vs.Antidilutive
　　Market price>Exercise price，Dilutive
　　Market price<Exercise price，Antidilutive
　　If the security is antidilutive，ignore it during calculating dilutive EPS.因为没有投资人会傻到当market price<exercise price时，还行权
　　“If-converted” method are adopted during calculating the dilutive EPS.If-converted method assumes that the securities were converted to C/S at the beginning of the period（or at the time of issue，if later）
　　Diluted EPS=[Income available to C/S + interest on dilutive securitiesX（1-Tax rate）]/[WACSO，assuming all dilutive securities are converted to C/S]
　　Dilution from Options，Warrants，and their Equivalents–Treasury Stock Method.
　　The equivalents of options and warrants include nonvested stock granted to employees，stock purchase contracts，and partially paid stock subscriptions.
　　Treasury Stock Method的逻辑是：
　　当期权行权时，会增加outstanding的股票，进而稀释EPS
　　如果用行权时所收到的金额，按市价购买库存股，会减少outstanding的股票，进而反稀释EPS
　　真正的增加的股票和稀释的效果是以上两者的综合
　　Additional shares outstanding=number of shares issued for option–[proceeds received for option exercise / average market price]
　　Proceeds received for option exercise=number of shares issued for option X exercise price
　　Diluted from Convertible Securities–If converted method
　　1st.计算Basic EPS
　　2nd.计算Additional C/S（按合同约定）
　　3rd. 计算Additional N/I.对Bonds，增加了Interest X（1-tax rate）。对P/S，无影响。
　　4th.计算 If-converted的EPS
　　5th. 取min（basic EPS，if-converted EPS）
　　存在多种潜在稀释证券时的计算顺序（同时有option，convertible P/S，convertible bonds）
　　独立原则。各种证券互不影响，互相独立。
　　按稀释性大小，先算稀释性*5的。实务中通常稀释性从大到小为option and warrants，convertible P/S，convertible bonds.
　　计算顺序的逻辑–稳健性原则。告诉投资人一个最小的Dilutive EPS.
　　Dilution from contracts that may be settled in cash or stock.
　　GR：presumed to be settled in C/S.
　　SR：Included in diluted EPS
　　逻辑–稳健性原则。告诉投资人一个最小的Dilutive EPS.
　　Dilution from contingent shares.
　　Contingent issuable shares depend on some future event or on certain conditions being met.
　　If all conditions for issuance are met，contingent shares are also included in BASIC EPS as of the beginning of the period in which the conditions were satisfied.
　　If NOT，contingent shares are also included in Dilutive EPS.
　　Disclosures of EPS
　　Reconciliation of the numerators and the denominators of the basic and diluted EPS.
　　The effect of P/S dividend（in arrears）
　　Potentially dilute EPS but not included
　　Subsequent issues which may effect EPS
　　Cash flow amount per share are NOT disclosed
　　Summary of EPS（F7-31）重要
　　FAR F7-3 Statement of cash flows
　　Cash flow statement（C/F）is composed by：
　　operating cash flows（CFO），which is from transactions reported on the I/S，and Current assets and current liabilities.
　　Investing cash flows（CFI），which is from noncurrent assets.
　　Financing cash flows（CFF），which is from debt and equity.
　　Cash and cash equivalents
　　Cash is defined as actual cash（i.e.，currency and demand deposits）
　　Cash equivalents are defined as short-term，liquid investment，that are：
　　Quickly convertible into specific amounts of cash
　　So near maturity that the risk of changes in the value because of interest rate changes is insignificant.
　　CFO+CFI+CFF=the end cash and cash equivalent-the begin cash and cash equivalent
　　Methods of presenting the statement of C/F
　　The direct method（encourage）
　　The indirect method
　　Direct / Indirect method only different on CFO.The CFI & CFF is the same.
　　Under the direct method，the CFO shows the major classes of operating cash receipts and disbursements.A reconciliation of NI to CFO is required to be provided in a separate schedules under U.S. GAAP.
　　Indirect method CFO=NI+Noncash Expense/Loss–Noncash Income/Gains+Increase in operating liabilities–Increase in operating assets.
　　间接法下的正负号的逻辑：
　　现金及等价物是资产。
　　同性相斥，异性相吸。
　　资产的增加，减少CFO.
　　负债的增加，增加CFO.
　　CFO involve producing goods and delivering services to customers.
　　All transactions not categorized as CFI & CFF are categorized as CFO.
　　Direct method–categories to report
　　Cash received from customers=Revenue+increase in unearned revenue–increase in AR
　　Interest received
　　Dividend received
　　Direct method–categories to report（Cont‘）
　　Other operating cash receipts
　　Cash received from the sales of trading securities
　　Cash paid to suppliers and employees=COGS+increase in inventory–increase in A/P+salaries and wages expense–increase in wages payable
　　Interest paid
　　Direct method–categories to report（Cont‘）
　　Income taxes paid
　　Cash paid to acquire trading securities
　　Other operating cash payments=other operating expenses+increase in prepaid expenses–increase in accrued liabilities.
　　Indirect Method–adjustment to NI
　　All deferral of past operating cash receipts and disbursements.
　　All accruals of expected future operating cash receipts and disbursements.
　　All items that are included in NI that do NOT affect operating cash receipts and disbursements.
　　Indirect method CFO=NI+Noncash Expense/Loss–Noncash Income/Gains+Increase in operating liabilities–Increase in operating assets.
　　Indirect method CFO=“CLAD”
　　Current assets and liabilities
　　Losses and gains
　　Amortization and depreciation
　　Deferred items
　　Short-Cut Cash Flow Effects
　　Changes in debit balance accounts will have the opposite effect on cash flows
　　Changes in credit balance accounts will have the same effect on cash flows
　　Gains and Losses–CFI
　　Gains are subtracting from NI
　　Losses are adding to NI
　　Investing Activities include cash flows from the purchase or sale of NONCURRENT assets.
　　Making loans to other entities
　　Purchasing or disposing of trading，AFV，HTM
　　Acquiring or disposing of PP&E
　　Acquiring under acquisition method using cash.
　　Financing activities include cash flow from noncurrent liability and equity activities.
　　Obtaining resources from owners（issue stock）
　　Providing owners with return（dividend）
　　Obtaining resources from creditors（bonds）
　　Payments of principal on amount borrowed
　　Non cash investing and financing activities should be provided separately in a supplemental disclosure. Include：
　　A purchase of PP&E by issuance of stock
　　Conversion of bonds to equity
　　Acquiring assets through a capital lease obligation
　　The exchange of one noncash asset for another noncash asset
　　Summary of cash flow classifications of individual transactions （F7-38）。重要。
　　IFRS differences in reporting cash flow（F7-39）
　　Interest received
　　Interest paid
　　Dividends received
　　Dividends paid
　　Tax paid
