Money Terms in Plain English.

Terms marked UK are specific to the UK. A nation's name, like Scotland, means the rule only applies there.

U

UCITS

In plain English:A set of European rules that funds must follow to be sold to everyday investors, with limits on risk and how they're spread.
MoreLess about UCITS

UCITS stands for Undertakings for Collective Investment in Transferable Securities. Funds following it have rules to protect investors.

For example: A UK investor buys an ETF that follows UCITS rules, so it must spread its money across many holdings.

UFPLS (uncrystallised funds pension lump sum)UK

In plain English:Taking money straight out of your pension pot as a lump sum. A quarter of each amount is tax-free and the rest is taxed as income.
MoreLess about UFPLS (uncrystallised funds pension lump sum)

Usually a quarter of each one is tax-free, up to £268,275 across all your pensions, and the rest is taxed as income.

UFPLS stands for uncrystallised funds pension lump sum. Each payment has its own tax-free part.

In plain English:Share options from your employer that have no tax breaks. When you use them, the gain is taxed as income.
MoreLess about Unapproved share options

They're used when a company can't use EMI. The company may get a tax deduction.

Underwriting
How an insurer weighs up the risk of covering you.
In plain English:An insurer looks at your health, age and other details to decide whether to cover you and how much to charge.
MoreLess about Underwriting

Being honest on forms matters. Some insurers do it after a claim.

For example: An insurer asks about someone's health and lifestyle, then offers cover at a higher price because they smoke.

Unemployment rate
The share of people who want a job but can't find one.
In plain English:The share of people who want a job and are looking for one, but don't have one.
MoreLess about Unemployment rate

It's measured by a survey, not just by benefit claims. Rising unemployment can lead to lower interest rates.

Unicorn (start-ups)
A private start-up valued at over a billion dollars.
In plain English:A young company that isn't on the stock market but is valued at over a billion dollars.
MoreLess about Unicorn (start-ups)

Unit trustUK
An older type of UK fund.
In plain English:An older type of UK fund where people's money is pooled. It works much like an OEIC.
MoreLess about Unit trust

Many have become OEICs. They work much the same for investors.

Universal CreditUK
The main monthly benefit for working-age people on a low income or out of work.
In plain English:A monthly payment for people of working age on a low income or out of work. It replaced several older benefits.
MoreLess about Universal Credit

Savings over £6,000 reduce it, and over £16,000 there is usually none.

It's paid monthly and can include help with rent and childcare. Claims are made online.

For example: Someone working part-time on a low wage gets Universal Credit each month, which goes down as their earnings go up.

Unrealised and realised gains
A rise in value on paper, and a profit you've locked in by selling.
In plain English:An unrealised gain is a rise in value you haven't cashed in yet. Once you sell, it becomes a realised gain and may be taxed.
MoreLess about Unrealised and realised gains

Unrealised gains can disappear if prices fall. Only realised gains count for Capital Gains Tax.

For example: Someone's shares rise from £1,000 to £1,500. The £500 gain is unrealised until they sell.
