As of Tuesday morning, Amazon has begun issuing account credits to Kindle book buyers as a result of legal settlements with book publishers including Harper Collins and Simon & Schuster, which allegedly conspired with Apple to fix e-book prices in 2012.

Amazon is not disclosing the formula for calculating the credits, but it says that the settlements address "qualifying Kindle books purchased between April 1, 2010 and May 21, 2012." This reporter was given a tidy sum of $12.18 in her inbox, while Senior Business Editor Cyrus Farivar received $22.42 and Deputy Editor Nate Anderson picked up 73 cents.

According to the office of New York Attorney General Eric Schneiderman, the settlements with the five publishers accused of price fixing—Hachette, HarperCollins, Simon & Schuster, Macmillan, and Penguin—total $166 million nationwide. Customers who bought e-books from Barnes and Noble, Kobo, and Apple will also be receiving account credits, whereas those who bought e-books from Sony will receive checks in the mail.

While all of the publisher defendants settled the case, Apple continues to fight about its role in the price conspiracy. The company was found guilty in July of conspiring to fix e-book prices and was asked by the state attorneys general involved in the case to pay a total of $840 million in damages. Apple filed an appeal in October 2013.

The Amazon credits issued are valid for just over a year, through March 31, 2015, and can be used toward either e-books or physical paper books. Amazon writes that all eligible customers will be notified of their credits by March 25, 2014.
