Cartwright Springs Brewery Ltd. (CSB) operates a microbrewery and sells beer directly to customers, bars, and restaurants. CSB uses one-litre blue glass refillable bottles featuring a swing-top ceramic lid. The bottles cost CSB $4.90 each. CSB charges customers a refundable deposit of $5 for each bottle at the point of sale of their beer and records amounts received to the account Returnable Deposits. The $5 deposit amount is standard for this specialized segment of the micro beer industry and is close to the cost of the bottles. In addition, since the bottle returns must be made at the brewery location, CSB is using this relatively high deposit amount as a marketing strategy because it pro- vides an incentive for customers to return to the brewery to have their bottles refilled. Based on past experience, CSB estimates that 60% of the bottles do not get returned for refund. CSB makes an adjustment at the end of the fiscal year for unreturned deposits to the account Container Sales Revenue.
