"For men use to write an evill turne in marble stone, but a good turne in the dust." [More, 1513]To write (something) off (1682) originally was from accounting; fig. sense is recorded from 1889. Write-in "unlisted candidate" is recorded from 1932.
write off
Case Study In September 2001 Blockbuster, Inc., announced it would write off $450 million in the value of its videotape inventory. Tapes that, depending on age, had each been carried at a value of $4 to $8 would be valued at $2 under the new policy. In addition, Blockbuster said it would reduce the number of old tapes in each store from 8,000 to 6,000, thereby eliminating a quarter of its inventory of older tapes. More profitable DVD rentals had become an increasing part of Blockbuster's business, and the firm decided to devote more shelf space to these items. The charge, taken against second-half earnings, caused Blockbuster to report a large loss when Wall Street analysts had been expecting positive earnings. The unexpected news caused the firm's common stock to fall in price by over 8% on the day of the announcement. |
