Treasury bills are routinely issued at weekly tenders, held by the DMO on the last business day of each week (i.e. usually on Fridays), for settlement on the following business day. Treasury bills are typically issued at tenders with maturities of 1 month (approximately 28 days), 3 months (approximately 91 days), or 6 months (approximately 182 days).
Consignee and consignor - as pertaining to auctions, the consignor (also called the seller, and in some contexts the vendor) is the person owning the item to be auctioned or the owner's representative, while the consignee is the auction house. The consignor maintains title until such time that an item is purchased by a bidder and the bidder pays the auction house.
Due to the various governmental units that supply the vehicles for auction, there's no single reason for vehicles being brought to auction. Some of the vehicles are confiscated due to the former owner's involvement in drug dealing, smuggling, or fraud, while other vehicles were simply just abandoned. On exception, separate auctions will sometimes be held for very large seizures.
At times, customs may decide to not only seize goods but detain the passenger as well. This can happen for a number of different reasons. One reason is if, as mentioned above, a passenger has not declared the item(s) or if they have been declared falsely. Another reason would be if an individual carried with them over 200 grams of tobacco or a very large amount of alcohol.
