Assignment occurs when someone who has written, or sold, a listed option receives a notice that the option has been exercised and he or she must fulfill the terms of the contract by buying the underlying instrument if the option was a put or selling the underlying instrument if the option was a call.

Making the assignment is a two-step process. When an option listed on a US exchange is exercised, the Options Clearing Corporation (OCC) notifies a member broker-dealer firm with clients who have sold options in that series that one of those clients must meet the obligation to buy or sell. The firm, in turn, selects an individual client following its particular methodology, such as chronological order of sale or random choice.

As the writer of an in-the-money option, you should expect assignment, unless you close out your position with an offsetting contract. However, there is no guarantee that you will realize a profit or avoid a loss.

Assignment also means transferring property you own, such as stock and real estate, to someone else by using the document that's appropriate to the type of property. Similarly, property of a financially troubled entity can be assigned, or transferred, to a creditor and sold to offset losses.

In the quarter of random assignment, 91.5 percent of controls and 91.1 percent of program group members received welfare.
Random assignment does not control for differences in the environment of the groups (differences irrelevant to the treatment) or variation that the experimenter may introduce by treating the two groups differently.

If random assignment is not used (and sometimes even when it is), some important aspect may not be divided equally between the groups of subjects.
Also inherent in their responses are three guidelines to be addressed by follow-up treatment efficacy studies: (1) random assignment of participants to treatment conditions; (2) use of uniform assessment protocols across all participants; and (3) documentation of sufficient methodological detail to allow for independent replication.
Sixteen is, of course, an appreciable number of sites, more than that used in most random assignment evaluations of E&T programs, and perhaps too many to allow useful narrative synthesis to be conducted.
Quasi-experimental research designs are based on naturally occurring circumstances or institutions that (perhaps unintentionally) divide people into treatment and control groups in a manner akin to purposeful random assignment.
The authors report on their experiences in recruiting teachers for random assignment experiments in public primary and secondary schools.
The studies each use a random assignment research design, the "gold standard" in program evaluation.
The paper will consider non-clustered designs where (1) students are randomized to a treatment and control group, (2) clustered designs where units (such as schools or classrooms) are randomized, and (3) both stratified designs where random assignment is conducted within blocks (such as school districts or schools) and non-stratified designs.
Here's what the authors found: First, the measures of effectiveness from the 2009-10 school year did identify teachers who produced higher average student achievement following random assignment. Second, the magnitude of the achievement gains they generated was consistent with their expectations.
