Key Metrics

Current Yield

1.81%

At the Oct 29, 2026 price

The annual dividend as a percentage of the share price. A 3% yield is about $3 of dividends a year for every $100 invested at today's price.

Annualized Dividend

$0.3621

The latest declared regular dividend scaled to a full year by how often it's paid (for semi-annual payers, the latest two payments), adjusted for stock splits. A $0.25 quarterly dividend annualizes to $1.00. Special dividends are excluded.

Frequency

S Semi-Annual

How often the dividend is paid, read from the dates of recent payments: Q = quarterly (4x a year), M = monthly, S = semi-annual, A = annual.

RSI (14)

54

As of Oct 29, 2026

Relative Strength Index (0-100), a price-momentum gauge. Above 70 is often called 'overbought', below 30 'oversold'. A technical signal, not a dividend metric.

52-Week Range

$13.11 – $21.59

Closes through Oct 23, 2026

The lowest and highest price over the past year, showing where today's price sits in its recent range.

Payout Ratio

-

The share of earnings paid out as dividends over the trailing twelve months (TTM): dividends paid divided by net income across the company's four most recent reported quarters, dated by the latest quarter end. A fiscal-year tag such as FY2025 means only annual figures were available. Lower leaves more cushion; above 100% means paying out more than the company earned. It shows n/a for funds and when net income over the period was negative; for REITs and BDCs it is marked EPS-based, since they are judged on FFO/AFFO or net investment income instead.

Years Paying

17

How many years of payments we have on record. This can understate very long histories where our data doesn't reach far enough back.

Price / Book (TTM)

1.13

Price as of Oct 25, 2026; latest reported book value

Price-to-book ratio: the share price on the date shown divided by the latest reported book value per share. A rough valuation gauge, most useful for asset-heavy sectors like REITs, banks and insurers.

S.A.F.E. Dividend Read

S.A.F.E. is a set of four checks on a dividend's record and the company's data, the same test used across the screener and our ranked lists. Solid: a Dividend Safety Score of 70+ and a yield of 2%+. Accelerating: at least three consecutive completed calendar years of higher total regular dividends. Flawless: since 1990, no calendar year whose total regular dividend fell more than 20% below the year before, and no suspension. Enduring: at least 20 years between the first and latest dividend in our records. All four met earns the S.A.F.E. flag.
S Solid
Below the Solid check (Dividend Safety Score 70+ and yield 2%+): Dividend Safety Score 77/100, yield 1.81%.
A Accelerating
Dividend growth has stalled — 0 consecutive annual increase(s), under the 3 this check looks for.
F Flawless
A calendar year's regular dividend total fell more than 20% below the year before.
E Enduring
17 year(s) of payments on record, under the 20 this check looks for.

How often a record like this ends in a cut

Years the payout rose11Since Mar 2009
Rank among payers1014of 2,430 with a record
Years it fell over 20%2in 16 comparable years
Of peers with 10 to 24 up years75%also cut at some point

IDKOY has raised its annual dividend in 11 separate years since March 2009, which ranks 1014 among the 2,430 payers with a comparable record in our dataset. In 2 years the annual total fell by more than a fifth.

Of the 878 companies we track with 10 to 24 years of increases, 661 — 75 per cent — also have at least one year in which the dividend fell by more than 20 per cent. Across every company with twenty years of comparable history, only 277 of 1078 (26 per cent) have never cut. A long record of increases is common; a record with no cut anywhere in it is not.

Measured from annual totals using split-adjusted amounts, comparing only consecutive years with the same number of payments — a stock split and a payment shifting across a year boundary both look like cuts otherwise. The current year is excluded as incomplete. How we measure a cut, and what the corrections change. Figures are for information only, not a view on any security.

Why the Yield Moved (90 Days)

IDKOY's dividend yield fell from 2.29% to 1.81% over the past ~90 days (-0.48 pp). Of that move, -0.02 pp came from changes in the dividend rate and -0.46 pp from the share price ($15.96 on Aug 03, 2026 → $19.99 on Oct 29, 2026). A yield that rises because the price fell is not an improvement in the payout itself.
