Herfindahl–Hirschman Index
The Herfindahl index (also known as Herfindahl–Hirschman Index, HHI, or sometimes HHI-score) is a measure of the size of firms in relation to the industry they are in and an indicator of the amount of competition among them. Named after economists Orris C. Herfindahl and Albert O. Hirschman, it is an economic concept widely applied in competition law, antitrust and also technology management. HHI is calculated by squaring the market share of each competing firm in the industry and then summing the resulting numbers,(sometimes limited to the 50 largest firms), where the market shares are expressed as fractions or points. The result is proportional to the average market share, weighted by market share. As such, it can range from 0 to 1.0, moving from a huge number of very small firms to a single monopolistic producer. Increases in the Herfindahl index generally indicate a decrease in competition and an increase of market power, whereas decreases indicate the opposite. Alternatively, if whole percentages are used, the index ranges from 0 to 10,000 "points". For example, an index of .25 is the same as 2,500 points. The major benefit of the Herfindahl index in relationship to such measures as the concentration ratio is that it gives more weight to larger firms. Other benefits of the Herfindahl index includes its simple calculation method and the small amount of easily obtainable data required for the calculation. The measure is essentially equivalent to the Simpson diversity index, which is a diversity index used in ecology; the inverse participation ratio (IPR) in physics; and the effective number of parties index in politics.

United Express Flight 3411 Incident
Template:Infobox Aircraft occurrence The United Express Flight 3411 incident occurred at Chicago O'Hare International Airport, United States on April 9, 2017, when Dr. David Dao Duy Anh, a Vietnamese-American passenger, was injured while being forcibly removed from a fully boarded, sold-out flight to Louisville International Airport. Dao, a pulmonologist and folk musician, refused to surrender his seat when requested because he needed to see patients the following day. Chicago Department of Aviation Security officers were called to remove him from the plane; in the process, they struck Dao's face against an armrest, then pulled him, apparently unconscious, by his arms along the aircraft aisle past rows of onlooking passengers. Prior to the confrontation, United agents offered travel vouchers to passengers to vacate their seats to make room for four deadheading Republic Airways employees, but none of the passengers accepted. United then selected four passengers for involuntary removal from the flight, one of whom was Dao, and the three other passengers agreed to leave. Flight 3411 was operated by Republic Airways on behalf of United Express, a United Airlines regional branch. Video of the incident recorded by passengers went viral on social media, resulting in anger over the force that was used. Politicians expressed concern and called for an official investigation. Then-U.S. President Donald Trump criticized United Airlines, calling its treatment of Dao "horrible." The next morning, then-CEO of United, Oscar Munoz, issued a statement that appeared to justify the removal of Dao, referring to "re-accommodating the customers." Munoz also sent an email to United staff commending the crew's actions for following established procedures and referring to Dao as "disruptive" and "belligerent," though this characterization contradicted passengers' accounts of the incident. Passenger Jason Powell asserted that Dao was not belligerent, saying instead, "He was very polite, matter-of-fact." Cell phone video by passenger Joya Cummings also contradicted Munoz's description of Dao as belligerent. Munoz and United were sharply criticized for their initial statements, and United suffered a drop in its stock price. Two days after the incident, Munoz issued an additional statement, apologizing and promising that such an incident would never again occur on a United aircraft. He said, "No one should ever be mistreated this way." In an ABC television interview, Munoz was asked, "Do you think [Dao] was at fault in any way?" Munoz responded, "No. He can't be. He was a paying passenger sitting on our seat in our aircraft." Munoz's previously planned promotion to become United's chairman was delayed until May 2020 as a result of the incident. Dao reached an "amicable" settlement with United on April 27, 2017, though its terms were not publicly announced.

Clearing
In banking and finance, clearing denotes all activities from the time a commitment is made for a transaction until it is settled. This process turns the promise of payment (for example, in the form of a cheque or electronic payment request) into the actual movement of money from one account to another. Clearing houses were formed to facilitate such transactions among banks.

Risk-Free Interest Rate
The risk-free interest rate is the rate of return of a hypothetical investment with scheduled payment(s) over a fixed period of time that is assumed to meet all payment obligations. Since the risk-free rate can be obtained with no risk, any other investment having some risk will have to have a higher rate of return in order to induce any investors to hold it. In practice, to infer the risk-free interest rate in a particular currency, market participants often choose the yield to maturity on a risk-free bond issued by a government of the same currency whose risks of default are so low as to be negligible. For example, the rate of return on T-bills is sometimes seen as the risk-free rate of return in US dollars.

Factoring
Factoring is a financial transaction and a type of debtor finance in which a business sells its accounts receivable (i.e., invoices) to a third party (called a factor) at a discount. A business will sometimes factor its receivable assets to meet its present and immediate cash needs. Forfaiting is a factoring arrangement used in international trade finance by exporters who wish to sell their receivables to a forfaiter. Factoring is commonly referred to as accounts receivable factoring, invoice factoring, and sometimes accounts receivable financing. Accounts receivable financing is a term more accurately used to describe a form of asset based lending against accounts receivable. The Commercial Finance Association is the leading trade association of the asset-based lending and factoring industries. In the United States , Factoring is not the same as invoice discounting (which is called an assignment of accounts receivable in American accounting – as propagated by FASB within GAAP). Factoring is the sale of receivables, whereas invoice discounting ("assignment of accounts receivable" in American accounting) is a borrowing that involves the use of the accounts receivable assets as collateral for the loan. However, in some other markets, such as the UK, invoice discounting is considered to be a form of factoring, involving the "assignment of receivables", that is included in official factoring statistics. It is therefore also not considered to be borrowing in the UK. In the UK the arrangement is usually confidential in that the debtor is not notified of the assignment of the receivable and the seller of the receivable collects the debt on behalf of the factor. In the UK, the main difference between factoring and invoice discounting is confidentiality. Scottish law differs from that of the rest of the UK, in that notification to the account debtor is required for the assignment to take place. The Scottish Law Commission reviewed this position and made proposals to the Scottish Ministers in 2018.

Taxonomy of Product–Service System Perturbation
Perturbations have a negative influence on the operation of the business system, which may weaken business performance. Product–service system (PSS) perturbations could be classified into six categories, namely, behavioral, social, environmental, competence, resource, and organizational perturbations. The proposed terminology and taxonomy appear to be effective, which could enable researchers to understand the scope of PSS perturbations on a conceptual level. This finding is also expected to provide useful knowledge and information for researchers who are interested in vulnerability analysis and the robust design of PSS.

Individual Savings Account
An Individual Savings Account (ISA; /ˈaɪsə/) is a class of retail investment arrangements available to residents of the United Kingdom. It qualifies for a favourable tax status. Payments into the account are made from after-tax income. The account is exempt from income tax and capital gains tax on the investment returns, and no tax is payable on money withdrawn from the scheme either. Cash and a broad range of investments can be held within the arrangement, and there is no restriction on when or how much money can be withdrawn. Funds cannot be used as security for a loan. Until the Lifetime ISA was introduced in 2017 it was not a specific retirement product, but any type can be a useful tool for retirement planning alongside pensions.

Fund Manager
Investment management is the professional asset management of various securities (shares, bonds and other securities) and other assets (e.g., real estate) in order to meet specified investment goals for the benefit of the investors. Investors may be institutions (insurance companies, pension funds, corporations, charities, educational establishments etc.) or private investors (both directly via investment contracts and more commonly via collective investment schemes e.g. mutual funds or exchange-traded funds). The term asset management is often used to refer to the investment management of collective investments, while the more generic fund management may refer to all forms of institutional investment as well as investment management for private investors. Investment managers who specialize in advisory or discretionary management on behalf of (normally wealthy) private investors may often refer to their services as money management or portfolio management often within the context of "private banking". The provision of investment management services includes elements of financial statement analysis, asset selection, stock selection, plan implementation and ongoing monitoring of investments. Coming under the remit of financial services many of the world's largest companies are at least in part investment managers and employ millions of staff. It remains unclear if professional investment managers can reliably enhance risk adjusted returns by an amount that exceeds fees and expenses of investment management. The term fund manager (or investment advisor in the United States) refers to both a firm that provides investment management services and an individual who directs fund management decisions. According to a Boston Consulting Group study, the assets managed professionally for fees reached an all-time high of US$62.4 trillion in 2012, after remaining flat-lined since 2007. Furthermore, these industry assets under management were expected to reach US$70.2 trillion at the end of 2013 as per a Cerulli Associates estimate. The global investment management industry is highly concentrated in nature, in a universe of about 70,000 funds roughly 99.7% of the US fund flows in 2012 went into just 185 funds. Additionally, a majority of fund managers report that more than 50% of their inflows go to only three funds.
