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).
Alu elements are classified as SINEs, or Short INterspersed Elements. All Alus are approximately 300 bp in length and derive their name from a single recognition site for the restriction enzyme AluI located near the middle of the Aluelement. Human chromosomes contain about 1,000,000 Alucopies, which equal 10% of the total genome.
