For example, Northwind Traders, a gourmet food distribution company, likes to have a minimum number of all their products in stock. When they track their inventory, they include the number of units in stock and the number of units that they want to keep in stock (the reorder level). When the number of units in stock falls below the reorder level, they place another order.

Помогите, пожалуйста, перевести второе предложение.

Заранее спасибо.
