A standard adult football match consists of two periods of 45 minutes each, known as halves. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents, but is most commonly referred to as stoppage time or injury time, while loss time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. The referee alone signals the end of the match. In matches where a fourth official is appointed, toward the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.

Ah, so.. 45

The announcement came two years after Dell Inc. returned to private ownership, claiming that it faced bleak prospects and would need several years out of the public eye to rebuild its business. It's thought that the company's value has roughly doubled since then. EMC was being pressured by Elliott Management, a hedge fund holding 2.2% of EMC's stock, to reorganize their unusual "Federation" structure, in which EMC's divisions were effectively being run as independent companies. Elliott argued this structure deeply undervalued EMC's core "EMC II" data storage business, and that increasing competition between EMC II and VMware products was confusing the market and hindering both companies. The Wall Street Journal estimated that in 2014 Dell had revenue of $27.3 billion from personal computers and $8.9bn from servers, while EMC had $16.5bn from EMC II, $1bn from RSA Security, $6bn from VMware, and $230 million from Pivotal Software. EMC owns around 80 percent of the stock of VMware. The proposed acquisition will maintain VMware as a separate company, held via a new tracking stock, while the other parts of EMC will be rolled into Dell. Once the acquisition closes Dell will again publish quarterly financial results, having ceased these on going private in 2013.

Season four premiered on January 18, 2005; this was the first season of the series to be aired in high definition, although the finale of season three was also aired in high definition. The number of those attending the auditions by now had increased to over 100,000 from the 10,000 of the first season. The age limit was raised to 28 in this season, and among those who benefited from this new rule were Constantine Maroulis and Bo Bice, the two rockers of the show.
