The burn
Net cash consumed per period.
The part
What it is
Net rather than gross, since revenue offsets it, and averaged over enough periods that one unusual month does not dominate.
Committed future costs should be included, since a burn figure that excludes signed obligations understates the position.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
