“Revenue Recognition. The Company recognizes revenue when control of promised goods is transferred to customers in an amount that reflects the consideration the Company expects to receive in exchange for those goods. Revenue is recognized at a point in time, generally upon shipment, as this represents the transfer of the risk of loss and control to the carrier (F.O.B. shipping point). Shipping and handling activities are accounted for as fulfillment costs.”

Revenue Recognition. We follow a five-step model for revenue recognition. The five steps are: (1) identification of the contract(s) with the customer, (2) identification of the performance obligation(s) in the contract(s), (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligation, and (5) recognition of revenue when (or as) the performance obligation is satisfied. We fulfill our performance obligations when control of product transfers to the customer, which is generally at the time the product is shipped since risk of loss is transferred to the purchaser upon delivery to the carrier. For shipments which are free on board (F.O.B). shipping point, we have elected to account for shipping and handling activities as a fulfillment cost rather than as an additional promised service and performance obligation.

“The SPCH division also produces a chemical used in swimming pools and spas. The product forms a thin, transparent layer on the water’s surface. The transparent layer slows the evaporation of water, allowing the water to retain a higher temperature for a longer period of time thereby reducing the energy required to maintain the desired temperature of the water. A modified version of EWCP can also be used in reservoirs, potable water storage tanks, livestock watering pods, canals, and irrigation ditches for the purpose of reducing evaporation.”
