Trading Christmas is a 2011 Christmas film directed by Michael Scott and starring Faith Ford, Tom Cavanagh, Gil Bellows, Gabrielle Miller, Emma Lahana, and Andrew Francis.
 The film is based on the novel of the same name by author Debbie Macomber, who also serves as a producer.

The columns Song, Album, and Year list each song title, the official release on which the song first appeared, and the year in which the song was released for the first time.
 The columns Length, Author, and Producer indicate the length of the track, the author of the song (most often Wainwright alone), and the producer of the track.
 References are also provided for each song in the last column of the table.
 While many songs listed appear on multiple releases (for example, "Spotlight on Christmas" appears on "Maybe This Christmas Too?
", "The McGarrigle Christmas Hour", and "Elton John's Christmas Party"), songs are listed based on the first release and only appear twice when the recordings have different production information (producer, length, etc.).
Motion pictures featuring Santa Claus abound and apparently constitute their own subgenre of the Christmas film genre.
 Early films of Santa revolve around similar simple plots of Santa's Christmas Eve visit to children.
 In 1897, in a short film called "Santa Claus Filling Stockings", Santa Claus is simply filling stockings from his pack of toys.
 Another film called "Santa Claus and the Children" was made in 1898.
 A year later, a film directed by George Albert Smith in titled "Santa Claus" (or "The Visit from Santa Claus" in the United Kingdom) was created.
 In this picture, Santa Claus enters the room from the fireplace and proceeds to trim the tree.
 He then fills the stockings that were previously hung on the mantle by the children.
 After walking backward and surveying his work, he suddenly darts at the fireplace and disappears up the chimney.
 "Santa Claus' Visit" in 1900 featured a scene with two little children kneeling at the feet of their mother and saying their prayers.
 The mother tucks the children snugly in bed and leaves the room.
 Santa Claus suddenly appears on the roof, just outside the children's bedroom window, and proceeds to enter the chimney, taking with him his bag of presents and a little hand sled for one of the children.
 He goes down the chimney and suddenly appears in the children's room through the fireplace.
 He distributes the presents and mysteriously causes the appearance of a Christmas tree laden with gifts.
 The scene closes with the children waking up and running to the fireplace just too late to catch him by the legs.
 A 1909 film by D. W. Griffith titled "A Trap for Santa Claus" shows children setting a trap to capture Santa Claus as he descends the chimney, but instead capture their father who abandoned them and their mother but tries to burglarize the house after he discovers she inherited a fortune.
 A twenty-nine-minute 1925 silent film production titled "Santa Claus", by explorer/documentarian Frank E. Kleinschmidt, filmed partly in northern Alaska, feature Santa in his workshop, visiting his Eskimo neighbors, and tending his reindeer.
 A year later, another movie titled "Santa Claus" was produced with sound on De Forest Phonofilm.
 Over the years, various actors have donned the red suit (aside from those discussed below), including Monty Woolley in "Life Begins at Eight-thirty" (1942), Alberto Rabagliati in "The Christmas That Almost Wasn't" (1966), Dan Aykroyd in "Trading Places" (1983), Jan Rubes in "One Magic Christmas" (1985), David Huddleston in "" (1985), Jonathan Taylor Thomas in "I'll Be Home for Christmas" (1998), and Ed Asner in "Elf" (2003).
 Later films about Santa vary, but can be divided into the following themes.

Public holidays in the United Kingdom are days where most businesses and non-essential services are closed, although an increasing number of retail businesses (especially the larger ones) do open on some of the public holidays.
 There are restrictions on trading on Sundays and Christmas Day in England and Wales and on New Year's Day and Christmas Day in Scotland.
 Legally defined holidays, analogous to "public holidays" in many other countries, are usually called bank holidays in the United Kingdom, but can also be referred to as "public holidays"; strictly, however, "public holidays" refer to "common law holidays", the observance of which derive from custom and practice (see "Terminology" below).

Trailing Twelve Months (TTM) is a measurement of a company's financial health used in finance.
 It is measured by using the income statements from a company's reports (such as interim, quarterly or annual reports), to calculate the income for the twelve-month period immediately prior to the date of the report.
 This figure is calculated by analysts because quarterly and interim reports often show only income from the preceding 3, 6 or 9 months, not a full year.
 Because it does not represent a full year, this data can be skewed by seasonal trading patterns, such as higher sales over Christmas, giving a less accurate picture of a company's fiscal health.
