The age bands

Stock grouped by how long it has been held.

The part

What it is

Bands should be set against the item’s normal turnover rather than by calendar convention, since ninety days means different things for different products.

The oldest band is the one worth reading, and it is usually smaller in volume and larger in value than expected.

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.
