breakpoint[′brāk‚pȯint] (chemical engineering) breakthrough (computer science) A point in a program where an instruction, instruction digit, or other condition enables a programmer to interrupt the run by external intervention or by a monitor routine. (industrial engineering) In a time study, the end of an element in a work cycle and the point at which a reading is made. Also known as end point; reading point. breakpoint (programming)A point in a program that, when reached,triggers some special behavior useful to the process ofdebugging; generally, breakpoints are used to either pauseprogram execution, and/or dump the values of some or allof the program variables. Breakpoints may be part of theprogram itself; or they may be set by the programmer as partof an interactive session with a debugging tool forscrutinizing the program's execution.breakpointA point in the processing of a program that the programmer wants to observe more closely by stopping the program and examining the contents of variables, buffers and memory. Part of the debugging function, lines of code are marked as breakpoints. When those instructions are about to be executed, the program stops, and control is passed to the programmer. After inspection, the programmer can step through the program one line at a time or cause the program to continue running either to the end, to the next breakpoint or until it crashes, whichever comes first.

break·point (brāk'poynt), In helminth epidemiology, the critical mean wormload in a community, below which the helminth mating frequency is too low to maintain reproduction. Below this level, helminth infection in the community will progressively decline, ultimately to zero.Infectious diseases A level of minimum inhibitory concentration (MIC) at which a bacterium is deemed either susceptible or resistant to an antibiotic being used
Molecular biology A site in the DNA’s double helix where there is an interruption of both strands of nucleotides
Vox populi A popular term for a quantitative value or ‘point’ at which an event—e.g., a decision, action, or other response—is initiatedbreak·point (brāk'poynt) 1. In helminth epidemiology, the critical mean wormload in a community, below which the helminth mating frequency is too low to maintain reproduction. Below this level, helminth infection in the community will progressively decline, ultimately to zero. 2. A point in any continuous process or function at which an interruption, cessation, or change occurs. 3. In antimicrobial therapy, concentration of an antibiotic that can be achieved in body fluids or target sites during optimal therapy. Breakpoint
BreakpointFor mutual funds, the point at which the amount invested reduces the sales charge is called the "breakpoint." Each mutual fund may have several breakpoints; the larger the investment, the greater the discount. Note that the actual reduction in the sales charge is known as the "breakpoint discount". Also, the term "breakpointing" is sometimes used to refer to the offering of breakpoint discounts. The practice of soliciting mutual fund purchases just below the breakpoint (to earn more commissions) is considered unethical and in violation of NASD rules. See: right of accumulation.BreakpointIn loaded mutual funds, a dollar amount an investor must buy into the fund in order to be eligible for a reduced load or sales fee. For example, if the breakpoint for a certain mutual fund is $50,000, and investments beyond that amount will halve the load, it becomes advantageous for an investor to invest $50,000 instead of, say, $45,000, because this will entitle him/her to half the load for the entire investment, and not just for the amount invested past $50,000. Mutual funds that allow investors to buy at just below the breakpoint may run afoul of Financial Industry Regulatory Authority regulations. An investment need not come all at once to pass the breakpoint; an investor putting two tranches of $25,000 into the above mutual fund will usually find his excess load refunded. See also: Right of accumulation.breakpoint The cumulative level of purchases of shares in a mutual fund that is required before an individual purchaser can qualify for a reduced sales commission. Compare letter of intent. See also right of accumulation.Breakpoint.A breakpoint is the level at which your account balance in a mutual fund company or the size of a new investment in the company's funds qualifies you to pay a reduced sales charge. Fund companies that charge a percentage of the amount you invest as a front-end load, or sales charge, may offer this cost saving. They are not required to do so, but if they do use breakpoints, they must ensure that all clients who qualify get the discount. In most cases, the first breakpoint is $25,000, with further reductions for each additional $25,000 or $50,000 purchase. For example, if the standard load were 5.5%, it might drop to 5.25% at $25,000, to 5% at $50,000, and perhaps to as low as 2.5% with an investment of $250,000. In calculating breakpoints, some fund companies will combine the value of all of your investments in the mutual funds they offer. Other companies count the investments of all the members of your household or give you credit for purchases you intend to make in the future. EncyclopediaSeeb/p |
