A manufacturer with a product in the decline stage of the product life cycle would most likely decide to let current stocks of the product run out if there is reason to believe that there will be a small but continuing demand for the product.
When there is a decline in demand of a product, an organization most likely will stop producing as much of the item to see if sales pick up. If they do not pick up, they will probably let everything run out so that they aren't in the hole with their product any longer and producing a product that is not selling.
