The modified Dietz method [1] [2] [3] is a measure of the ex post (i.e. historical) performance of an investment portfolio in the presence of external flows. (External flows are movements of value such as transfers of cash, securities or other instruments in or out of the portfolio, with no equal simultaneous movement of value in the opposite direction, and which are not income from the ...
BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
In calculating current account, exports are marked as credit (the inflow of money) and imports as debit (the outflow of money). Services When an intangible service (e.g. tourism) is used by a foreigner in a local land and the local resident receives the money from a foreigner, this is also counted as an export, thus a credit.

The model describes how dissolved oxygen (DO) decreases in a river or stream along a certain distance by degradation of biochemical oxygen demand (BOD). The equation was derived by H. W. Streeter, a sanitary engineer, and Earle B. Phelps, a consultant for the U.S. Public Health Service, in 1925, based on field data from the Ohio River. The ...
The cash value of the bond will be credited to your checking or savings account within two business days of the redemption date. A minimum of $25 is required to redeem an electronic bond.
A cash flow (CF) is determined by its time t, nominal amount N, currency CCY, and account A; symbolically, CF = CF(t, N, CCY, A). Cash flows are narrowly interconnected with the concepts of value, interest rate, and liquidity. A cash flow that shall happen on a future day t N can be transformed into a cash flow of the same value in t 0.
To calculate the time-weighted return of these particular shareholdings, in isolation from the cash used to purchase the shares, treat the purchase of shares as an external inflow. Then the first sub-period growth factor, preceding the second purchase, when there are just the first 10 shares, is:
