Originally posted by mecrox I don't know how Nikon account for this in their books, but there seems to be a raft of semi-obsolete D3xxx or D5xxx out there the size of the Great Barrier Reef.
I don't have to do Nikon's books to know that it is a sale once a camera or lens is shipped to someone else. Third party distributors and dealers will have some time to pay Nikon, dating terms are used as an incentive to get larger orders, but at some point in the fiscal year that the cameras are shipped, they will come due. Smaller players like Pentax and Olympus may offer guaranteed inventory turns by agreeing to accept returns of unsold product without offsetting orders of new product, but Nikon won't have any such liability. Once the dealer pays for their Nikon stock, Nikon won't accept it back. That's why dealers have cameras in stock that have celebrated birthdays.
Because dealers have much of their money tied up in aged Nikon and Canon inventory, they are much less eager to tie up money in product from other manufacturers, which means that Pentax, Olympus, etc. customers will either be buying the display model or waiting for the dealer to order more stock. If Nikon and Canon want their dealers to order new models, they need to help them sell out old inventory, which is why dealers will advertise specials on Canon and Nikon products more often, but most camera buyers are looking to replace what they already own, not get into photography for the first time, so their preference is to buy the latest models, not something out of date. The brick and mortar camera stores are in the most difficult position, they keep losing customers to online dealers while they sit on outdated inventory that gets harder and harder to sell.
It isn't the buckets of unsold Nikon products in stores that is hurting Nikon, it is the overhead from a company set up to produce X million cameras and lenses every year, when demand is only half of that. It will take some time to reduce overhead and that will take cash out of the pockets of Nikon's owners, but Nikon isn't obligated to lose money forever. The only way Nikon becomes a total loss for its owners is if Nikon gets out of the camera business altogether.
