The incubation period averages 8-12 hours, after which diarrhea and abdominal cramps begin. C. perfringens symptoms usually persist for one day. A severe complication, necrotic enteritis (also known as pig-bel syndrome), can develop if large numbers of bacteria are ingested.
Absorption costing is a costing system which treats all costs of production as product costs, regardless weather they are variable or fixed. The cost of a unit of product under absorption costing method consists of direct materials, direct labor and both variable and fixed overhead.
Variable selling and administrative costs are critical components in both variable and absorption accounting calculations. Variable costs such as commissions, bonuses and utility bills vary based on product production and sales for the period, whereas fixed costs do not tend to fluctuate. Variable selling and administrative costs also must be distinguished from variable manufacturing costs, which often have similar account names.
