Tempore: Tempore (abbreviated to temp.)  in historical literature denotes a period during which a person whose exact lifespan is unknown was known to have been alive or active, or some other date which is not exactly known, usually given as the reign of a monarch.  The word is Latin, being the ablative singular of the noun "tempus, temporis", "time", thus meaning "in the time (of)".  It should be followed by a name in the genitive case.  The theoretical full form might be "vixit tempore Regis Henrici Primi" ("he/she lived in the time of King Henry the First") (i.e. 1100-1135).  The best known occurrence is in the Domesday Book of 1086, where the phrase "Tempore Regis Eduardi" (nominative case "Rex Eduardus"), meaning "in the time of King Edward (the Confessor)" appears in the entry for almost every manor, abbreviated as TRE.  It thus signifies the date range 1042–1066.  It is useful in historical literature because the names of many historical persons appear in surviving documents only in royal charters, possibly as witnesses, which can be dated to the reign of the originating monarch.

Teddybjörnen Fredriksson: "Teddybjörnen Fredriksson" ("Fredriksson, the Teddy bear") is a Swedish children's song by Lasse Berghagen who wrote it in 1969 to his 3-year-old daughter Malin.  It's one of Berghagen's most famous songs.  Many Swedish schools and pre-schools sing it and has been voted as the most popular children's song.  This song is about a person whose father gave him a teddy bear as birthday present when he was 4 years old and when he was married and got a 4-year-old daughter, he gave her a teddy bear.  This song made Berghagen famous for children, and the real "Teddy bear Fredriksson" is locked in a booth at Leksaksmuseet in Stockholm.

Methuselah (bond): The Methuselah is a type of bond with a 50-year maturity.  The term is a reference to Methuselah, the oldest person whose age is mentioned in the Hebrew Bible.  The issuance in Methuselahs has been increasing in recent years due to demand for longer-dated assets from pension plans, particularly in France and the United Kingdom.  Issuance of Methuselahs in the United States has been limited, however, as the U.S. Treasury does not currently issue Treasuries with maturities beyond 30 years, which would serve as a reference level for any corporate issuance.

Life Assurance Act 1774: The Life Assurance Act 1774 (14 Geo.  3 c.48, also known as the Gambling Act 1774) was an Act of Parliament of the Parliament of Great Britain, which received the Royal Assent on 20 April 1774.  The Act prevented the abuse of the life insurance system to evade gambling laws.  It was extended to Ireland by the Life Insurance (Ireland) Act 1866, and is still in force.  Prior to the Act, it was legally possible for any person to take out life insurance on any other person, regardless of whether or not the beneficiary of the policy had any legitimate interest in the person whose life was insured.  As such, the system of life insurance provided a legal loophole for a form of gambling: an insurance policy could be taken out on an unrelated third party, stipulating whether or not they would die before a set date, and relying on chance to determine if the "insurer" or "policy-holder" would profit by this event.
