The farmer always buys and sells at the
market auctions. A purchase/sale of stock involves a seller, a
‘lot’, an auctioneer, and bidder(s) plus the
general auction staff. One of the bidders ends up as the purchaser
(assuming the lot reached the reserve price).
A sale starts by the seller indicating the
reserve price to the auctioneer. The auctioneer initiates a bidding process by
describing the lot and determining the initial
starting price. To determine the starting price the auctioneer
repeatedly suggests lower and lower prices
until a bid is made/accepted. The bidding process then proceeds as he
repeatedly requests bids, indicates the current
bid (and bidder) and or accepts bids (and the
bidders indicate bids). Finally, the auctioneer accepts (or rejects if
below the reserve price) a final bid (5 seconds
without a bid) from one of the bidders, who is
deemed to be the purchaser. The sale is concluded by staff preparing an
invoice (and copies) which are distributed to
the purchaser and the accounts department
(for reconciliation). The purchaser settles up by paying the agreed
price, which is reconciled with/against the
invoice reconciliation copy. The accounting process ends by passing on
payment to the seller. Prior to doing this, commission is calculated
and deducted, by accounting, from the
purchaser's payment. If the bids do not reach the reserve price, the
lot is deemed to have been withdrawn and a
flat fee is charged to the seller.
The seller may withdraw at any time up until
the reserve is met.
