K – Is used as an abbreviation for 1,000. For example, $225K would be understood to mean $225,000, and $3.6K would be understood to mean $3,600. Multiple K's are not commonly used to represent larger numbers. In other words, it would look odd to use $1.2KK to represent $1,200,000.
Ke – Is used as an abbreviation for Cost of Equity (COE). Ke is the risk-adjusted, theoretical rate of return on a Company's invested excess capital obtained through external investments. Among other things, the value of Ke and the Cost of Debt (COD)[6] enables management to arbitrate different forms of short and long term financing for various types of expenditures. Ke applies most prominently to companies that regularly generate excess capital (free cash flow, cash on hand) from ongoing operations. Critically, in assessing a company's financial position (and reading its balance sheet), COE is distinguished from CAPEX, or costs associated with Capital Expenditures.[7][8] Ke is most often used in the Capital Asset Pricing Model (CAPM), in which Ke = Rf + ß(Rm-Rf). In this equation, Ke (COE) equals the anticipated return from the difference (Beta) of investment yields from a return based on market expectations (Rm)[9] and a Risk Free Rate (Rf), such as Treasury Bills or Bonds.
KPI – Key Performance Indicator, a type of performance measurement. An organization may use KPIs to evaluate its success, or to evaluate the success of a particular activity in which it is engaged.
KYC – "Know Your Customer" refers to due diligence activities that financial institutions and other regulated companies must perform to ascertain relevant information.
PWIN – Percent win (a measure of performance of capture when bidding for contracts with a targeted customer base such as bidding for government contracts) [13][14]
