How scores work
Every score shows its working.
Last updated 5 October 2026
A Faithful Invest score measures how a company lines up with one tradition’s investing guidelines. It is not a rating of the company as an investment, and it isn’t advice. This page sets out the rules as they run today.
In short
- The verdict comes from the official standard (AAOIFI Shari’ah Standard 21 for Islam, USCCB for Catholic, GuideStone for Evangelical).
- Figures come from the company’s own filings (SEC) checked against Yahoo.
- When the figures can’t settle a test we say ‘Needs review’.
- No AI is used, and news never changes a verdict.
- Companies are re-checked at least every 60 days.
The score, step by step
Catholic and Evangelical scores start from 100 and move only for the reasons below. Each one is shown on the stock page with the rule and its source.
- Starting point
- 100
- A company with no involvement found in anything its tradition excludes.
- Limited involvement
- up to −25
- Something the tradition allows with a cost, such as conventional weapons for Catholics or a shop that sells alcohol for Evangelicals. The deduction is named on the stock page.
- An open question
- 50 to 74
- Something the evidence cannot settle yet, such as a hospital group whose services are not published.
- A rule broken
- 1
- An activity the tradition excludes, with the source quoted.
The result falls into one of three bands:
- Aligned 75 and above
- Needs review 50 to 74
- Not aligned 1: a rule broken
- Not enough data No business or financial figures to score
Islamic results work differently: the verdict comes from the AAOIFI tests, and the score stays inside the verdict’s band. Compliant companies score 75 to 100, higher the further they are from the limits; companies that need review score 50 to 74; a company that fails a test scores 1. News never changes an Islamic or Christian score.
Business activities
We look for revenue from industries each tradition excludes. When a company reports its business segments to the SEC, we use those figures. Otherwise we estimate from its industry classification and company description, and the stock page says the figures are estimated.
Catholic (USCCB SRI Guidelines)
Score bands: Fail 1; Needs review 50–74; Pass 75–100, 100 = no involvement found.
Abortion, euthanasia and assisted suicide
“The USCCB will not invest in any company whose activities include direct participation in or support of abortion, euthanasia or assisted suicide.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy I.1
Fails a company that makes a product approved or marketed for abortion, or performs abortion, euthanasia or assisted suicide. A drug with the same ingredient approved for something else does not count.
In vitro fertilization
“The USCCB will not invest in companies that utilize in vitro fertilization for either assisting conception or for research.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy I.3
Fails a company that performs IVF (runs fertility clinics or IVF laboratories) or uses IVF in research. The policy names companies that utilize IVF; makers of equipment or media sold to IVF clinics are not named, so they are not failed on it.
Embryo and fetal research
“The USCCB will not invest in companies that engage in scientific research on human fetuses or embryos that results in the end of pre-natal human life”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy I.4
Fails a company whose research destroys human embryos or uses fetal tissue from abortion.
Human cloning
“The USCCB will not invest in companies that engage in scientific research whose purpose is the cloning of human beings and/or develops products and services from such research.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy I.5
Fails a company researching human cloning or selling products from it.
Pornography
“The USCCB will not invest in a company whose sole purpose is to appeal to an indecent interest in sex or to incite sexual excitement through the production of sexually explicit films, videos, or internet sites or services.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy II.5
Fails a company whose main business is producing pornography. A distributor passes with a lower score: the bishops ask to engage distributors, not to exclude them.
Gender-transition procedures
“The USCCB will not invest in companies that directly participate in the performance of surgeries or in the administration of drugs or hormones for the purposes of delaying normal puberty or modifying the body’s appearance and/ or functions in order to express an identity incongruent with one’s biological sex.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy II.8
Fails a hospital or clinic operator that performs these surgeries or administers these drugs. Making a drug that is also used this way does not count; the policy is about performing and administering.
Contraceptives
“The USCCB will not invest in companies that manufacture contraceptives or derive more than 10% of their revenue from the sale of contraceptives, even if they do not manufacture them.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy II.11
Fails any contraceptive manufacturer, and any seller earning over 10% of revenue from contraceptives. A smaller seller passes with up to 25 points off. Devices for permanent sterilisation count as contraceptives: the US FDA classifies them as contraceptive devices "used to prevent pregnancy", and Humanae Vitae 14 names direct sterilisation alongside contraception.
Weapons of mass destruction
“The USCCB will not invest in firms that derive any revenue from the production of weapons inconsistent with Catholic teaching on war (e.g., biological and chemical weapons, landmines, nuclear weapons, weapons of mass destruction, etc.).”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy III.1
Fails a company with any revenue from producing nuclear, biological or chemical weapons or landmines, the weapons the policy names. Nuclear weapons include their warheads and components, the missiles and re-entry vehicles built only to carry them, and running the government plants that make them. Ships and aircraft that can carry such missiles count as conventional weapons.
Gambling, tobacco and recreational cannabis
“The USCCB will not invest in companies whose primary purpose is to derive revenue from gambling or the production of tobacco or the recreational use of cannabis.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy III.3
Fails a company whose main business (over half its revenue, our reading of "primary purpose") is gambling, making tobacco or recreational cannabis. A smaller share passes with up to 25 points off.
Conventional weapons
“The USCCB will engage companies through corporate dialogues, proxy voting, and support of shareholder resolutions efforts to limit weapons production, to limit foreign sales of weapons, and to convert corporate capacity to non-military uses.”
Source: USCCB Socially Responsible Investment Guidelines (November 2021), Policy III.2
Not an exclusion: the bishops engage weapons makers rather than exclude them. A company making conventional weapons passes with 15 to 25 points off, more for a larger share; 25 when the share is not reported.
Why weapons makers can pass the Catholic screen
The Church teaches that governments may defend their people and should regulate the arms trade. It excludes weapons of mass destruction, and warns that an industry thriving on war is a reprehensible business. The US bishops engage conventional weapons makers instead of excluding them. So a weapons maker passes, with a lower score, unless it makes the weapons the bishops name.
Why alcohol is not excluded for Catholics
None of the bishops’ "will not invest" policies covers alcohol. For addictive products the bishops ask investors to press companies to move away from them, not to sell their shares.
What this screen doesn’t cover
The bishops also ask investors to avoid, or consider divesting from, companies with persistent human-rights abuses, media companies resisting a human-rights policy, and companies that seriously harm the climate, biodiversity or water without remedying it (policies II.1, III.5, V.2, V.4, V.5 and V.9). Judging this needs an assessment of each company’s conduct that annual reports cannot give, so we don’t screen it.
Evangelical (GuideStone Funds)
Score bands: Fail 1; Needs review 50–74; Pass 75–100, 100 = no involvement found.
Abortion
“do not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.”
Source: GuideStone Funds prospectus (SEC Form 485BPOS, 30 July 2026), Principal investment strategy
Fails a company that makes a product approved or marketed for abortion, or performs abortions.
Pornography and adult entertainment
“do not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.”
Source: GuideStone Funds prospectus (SEC Form 485BPOS, 30 July 2026), Principal investment strategy
Fails a company that produces or distributes pornography or adult entertainment. We read "sexual immorality" only this narrowly; GuideStone does not define it further.
Alcohol
“do not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.”
Source: GuideStone Funds prospectus (SEC Form 485BPOS, 30 July 2026), Principal investment strategy
A company fails if it makes or sells this as a business, or reports a division or product line in it. A shop, restaurant or hotel that sells it alongside everything else passes, 10 points lower, with the involvement named. GuideStone sets no threshold; this is our reading of "publicly recognized for offering".
Tobacco
“do not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.”
Source: GuideStone Funds prospectus (SEC Form 485BPOS, 30 July 2026), Principal investment strategy

GuideStone sets no threshold; this is our reading of "publicly recognized for offering".
Gambling
“do not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.”
Source: GuideStone Funds prospectus (SEC Form 485BPOS, 30 July 2026), Principal investment strategy
A company fails if it makes or sells this as a business, or reports a division or product line in it. A shop, restaurant or hotel that sells it alongside everything else passes, 10 points lower, with the involvement named. GuideStone sets no threshold; this is our reading of "publicly recognized for offering".
Why shops and restaurants that sell alcohol, tobacco or lottery tickets can pass
GuideStone excludes companies "publicly recognized" for offering these products and publishes no threshold. We fail the companies that make or sell them as a business and pass those that sell them alongside everything else, 10 points lower.
What this screen doesn’t cover
GuideStone keeps a private list of excluded companies and may exclude more than its published rules name ("including, but not limited to"). We apply only what GuideStone publishes, so a company can pass here and still be on GuideStone’s private list.
Islamic (AAOIFI Shari’ah Standard 21)
- Main business excluded (3/4/1)
- The company’s main business must not be one Shariah prohibits, for example dealing in interest (conventional banking, lending and insurance), alcohol and other intoxicants, pork, gambling, pornography and adult entertainment, or trading futures and options. Fee-based financial firms that don’t lend — data providers, exchanges, asset managers, card networks — are judged on their own figures rather than excluded outright, except that futures-and-options exchanges are excluded under Standard 20.
- Prohibited income
- revenue from those activities plus all interest income: at most 5% of total revenue (3/4/4)
We apply the standard as written. It doesn’t prohibit defence, tobacco, music, cinema, TV or hotels, so they aren’t excluded, although some index providers exclude them. A hotel’s or a supermarket’s sales of alcohol or pork still count toward the 5% limit.
We decide a company’s main business from its official SEC industry code and its industry classification. How much of its revenue each activity brings comes from the company’s own reported or documented figures — its annual report, or a source on our curated list. A mention in a company’s description never counts as revenue. When a company sells something prohibited on the side — a supermarket selling alcohol, say — and doesn’t report how much, we use a documented figure if one exists; otherwise the result is Needs review, naming what isn’t reported.
For companies that file with the SEC, we read revenue by division and by product line from their latest annual report. A division whose name clearly names a prohibited business, such as ‘Pork’, ‘Beer’ or ‘Casinos’, counts toward the 5% limit (3/4/4), and above half of revenue it is the main business (3/4/1). A name that only might mean one, such as ‘Credit’ or ‘Financial Services’, gives Needs review until someone reads the report. We can only see what a company reports separately: a prohibited product sold inside a wider division, such as bacon within ‘Prepared Foods’, is covered by industry estimates and Needs review instead.
Islamic banks and insurers that run entirely on Shariah contracts pass the business test, and the financial ratios below don’t apply to them, as S&P and MSCI also do.
Financial ratios
Islamic screening follows AAOIFI Shari’ah Standard 21. A company is compliant only if it passes every test below; the stock page shows each one with our figure and the limit.
Islamic (AAOIFI Shari’ah Standard 21)
- Interest-bearing debt
- Everything the company has borrowed at interest (loans, bonds, commercial paper and finance leases) must be under 30% of its market value. We use the average market value over the last 36 months, so one good or bad month doesn’t decide it. (AAOIFI Shari’ah Standard No. 21, clause 3/4/2)
- Cash and interest-bearing investments
- Cash and interest-bearing investments must be under 30% of the same 36-month average market value. We count all cash, because companies don’t say which accounts earn interest. (AAOIFI Shari’ah Standard No. 21, clause 3/4/3)
- Prohibited income
- Income from prohibited activities, including interest earned, must be no more than 5% of the company’s total revenue. Any such income must be purified (see Purification). (AAOIFI Shari’ah Standard No. 21, clause 3/4/4)
- Not just cash and debts
- If cash, investments and money owed to the company make up 90% or more of its total assets, trading its shares is close to trading money or debts, which has its own rules. We flag it for review rather than failing it. (AAOIFI Shari’ah Standard No. 21, clause 3/17–3/18)
Figures come from the company’s latest annual report. For companies that file with the SEC we read the filing and check it against Yahoo Finance; for others we use Yahoo alone and say so. Debt means borrowing: loans, bonds, commercial paper and finance leases, not bills from suppliers, tax, pensions or ordinary rent. Cash counts all of it, because companies don’t say which accounts earn interest.
When a figure isn’t reported, we try a safe upper estimate: if even that passes, the test passes. When the estimate can’t settle it, or our two sources disagree in a way that changes the answer, the result is Needs review rather than a guess.
Financial ratios apply only to Islamic screening. Catholic and Evangelical guidelines don’t set financial limits.
Purification and Zakat
The company’s prohibited income for the year, divided by its number of shares, is the amount per share to give to charity. It applies to whoever holds the shares at the end of the company’s financial year, whether or not a dividend was paid.
AAOIFI Shari’ah Standard 21 (3/4/6) sets the rule for purification: the company’s prohibited income for the year, interest included, divided by its shares. Whoever holds the shares at the end of the company’s financial year gives that amount per share to charity, whether or not a dividend was paid. Where interest income isn’t reported separately, we use an upper estimate and say ‘at most’. Faithful Invest’s portfolio page adds it up for your holdings.
The portfolio page also estimates Zakat on your shares, following AAOIFI Shari’ah Standard 35. If you hold shares long term, Zakat is due on the company’s zakatable assets per share (clause 4/2/4): its cash, the money owed to it and its stock of goods, less its share of the debts it must pay within the year (clauses 2/1/1 and 6/1/2). Reports don’t say which debts paid for which assets, so we deduct them in proportion to the company’s zakatable assets, as clause 6/2/3 directs; long-term debts aren’t deducted (6/1/1). If you trade shares, they count as trade goods and Zakat is due on their market value (4/2/4, 5/2/2). The rate is 2.5% for a lunar year, or 2.577% if you count a solar year (3/2/4).
The estimate covers your shares only. Whether Zakat is due depends on nisab (85 grams of gold, clause 3/2/2) and on the rest of your wealth, which we don’t see. It isn’t religious or financial advice.
Positive signals
Faithful Invest does not award bonus points for positive signals or keyword matches. Scores strictly reflect adherence to each tradition’s published guidelines and financial standards.
Recent news
Company pages show the latest headlines from Yahoo Finance, for context only. Nothing reads or scores them: no AI is used anywhere in a result. Screening uses the company’s reported figures and verified activities, never headlines, so news never changes a verdict or score.
Funds and ETFs
A fund is scored from the companies inside it. We follow the index the fund copies, such as the S&P 500 or MSCI World, and check every company in that index against your tradition. Funds that copy the same index share one score: VOO, IVV, SPY and the S&P 500 funds sold in Europe all get the same result.
How a fund’s score is worked out
- The companies
- Every company in the index, with its share of the index, from the daily holdings of a fund that has to hold it
- The score
- The average of the companies’ scores, weighted by each company’s share of the index
- Equal-weight funds
- Every company counts the same, so the score is the plain average
- Hard limits
- Never averaged away: the page shows how many companies break one and how much of the fund they are
- Companies without a score
- Left out of the average; the page shows how much of the fund’s value has a score
- The verdict
- The usual bands, shown once at least 80% of the fund’s value has a score
- Updates
- Company lists every day; each company is checked again at least every 60 days
A fund can hold slightly different companies from its index, some cash, or derivatives. A few funds don’t hold the companies at all and earn the index’s return through a swap contract; their page says so. Funds that follow an index we don’t cover show their price and details, and you can ask us to add them. Checking a fund doesn’t use one of your daily checks.
Data and its limits
- Financial statements and segments come from SEC EDGAR filings or, for European companies, ESEF annual reports where available; prices, profiles and headlines come from Yahoo Finance.
- Companies with neither an SEC filing nor an ESEF report, for example in Switzerland, Canada or Australia, are checked on Yahoo Finance data only, which is less precise.
- Fund scores depend on the holdings fund companies publish and on our check of each company. Companies we can’t identify or score are left out of the average and shown as not scored.
- Scores can change as new filings come out and company activities are updated.
- Faithful Invest is for information only. It doesn’t recommend buying or selling anything. Speak to a qualified adviser before you invest.
