Employee stock options are similar to exchange traded call options issued by a company with respect to its own stock. At any time before exercise, employee stock options can be said to have two components: time value and intrinsic value. Any remaining time value component is forfeited back to the company when early exercises are made.
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).
An ALU can be programmed to perform any series of complicated arithmetic or logical calculations. It is the computational capacity of the ALU that determines the power of a computer systemâs CPU. In more complex systems, the ALU is divided into two units: the arithmetic unit (AU) and the logic unit (LU).
