Who owns the company's shares and how much leadership has at stake
When leaders own 20%+, they win when you win and lose when you lose
Few fund managers own this — expect less research and analyst coverage
Shares freely traded on the ASX by individual investors like you
Leadership owns a solid 52.9% of the company, which is encouraging. However, professional fund managers aren’t heavily involved (5.5%), so there may be less analyst coverage and research available. This can mean the stock is overlooked — a potential opportunity if the fundamentals are strong.

Why It Matters
Ownership mix affects governance incentives, liquidity, and share-price behaviour under large portfolio rebalancing flows.
Formula
Public Float (%) = 100 - Insider Ownership (%) - Institutional Ownership (%)Method
Use reported ownership percentages, convert to percentage terms, and compute remaining public float as the residual.
Worked Example
If insiders own 52.9% and institutions own 5.5%, public float is 41.5%.
How to Interpret
Higher insider ownership can improve alignment of incentives, while dominant institutional concentration can amplify short-term price moves.

Why It Matters
Debt-to-equity shows balance-sheet risk. Lower leverage usually means more flexibility when earnings soften.
Formula
Total Debt / Shareholders' EquityMethod
Compare current D/E against the industry threshold used in the scoring framework, then assess remaining headroom.
Worked Example
This company's D/E is 0.47, meaning it carries 47 cents of debt for every $1 of equity. The utilities & energy infrastructure limit is 1.50, leaving 1.03 of headroom.
How to Interpret
Lower values generally imply lower refinancing pressure and lower dividend stress in downturns.
Low debt means this company isn't at risk of cutting dividends to service loans during downturns. Your income stream is protected by a strong balance sheet.

Status
Positive
Why It Matters
Free cash flow is the cash available after core operating and capital needs. It is central to dividend capacity.
Formula
Operating Cash Flow - Capital ExpendituresMethod
Review whether free cash flow is consistently positive and whether it is sufficient relative to dividends and debt needs.
Worked Example
This company generated $53M in free cash flow — cash left after operating costs and capital expenditure. Positive FCF means dividends are funded by real cash generation.
How to Interpret
Persistently negative free cash flow can force reliance on borrowing or equity issuance to maintain payouts.
Positive cash flow means dividends are funded by actual money, not accounting profits. As Buffett says, "Cash is fact, profit is opinion." Your income is backed by real cash generation.

Why It Matters
ROE shows how effectively management turns shareholder capital into profit. High and stable ROE can signal pricing power, cost discipline, or both.
Formula
Net Income / Shareholders' Equity x 100Method
Use the 10-year average ROE and review the weakest year to check whether returns stayed resilient across cycles.
Worked Example
This company's 10-year average ROE is 5.1%, meaning each $1 of shareholder equity generates $0.05 in annual profit. The threshold is 10%, and the worst single year was 0.0%.
How to Interpret
Higher and steadier ROE generally supports stronger long-term compounding. Large drawdowns in weak years can point to fragility.
Lower ROE means your investment compounds more slowly. At 5.1%, this business needs more capital to generate the same returns as competitors. Consider whether other strengths (yield, stability) compensate for weaker profitability.

What percentage of the stock price comes back as earnings each year
4.0% earnings yield is below the 6.0% threshold. You'd earn nearly as much from safer government bonds, which means the extra risk of owning shares isn't being compensated.

Why It Matters
Earnings yield reframes valuation as return on price paid. It helps compare equity earnings power against lower-risk alternatives.
Formula
(Earnings per Share / Stock Price) x 100Method
Calculate current earnings yield, then compare it to the required yield for the stock's industry setting.
Worked Example
With EPS of $0.23 and a share price of $5.65, earnings yield is 4.0%. The required yield for this industry is 6.0% (based on 4.5% government bond rate plus a risk premium).
How to Interpret
A yield above the required level suggests better valuation support; below it indicates thinner compensation for equity risk.
Returns don't justify the added risk compared to safe bonds. Consider whether the dividend yield alone compensates, or wait for a better price.

Why It Matters
Consistency in EPS helps distinguish resilient earnings power from one-off performance spikes.
Formula
Positive EPS Years / Available EPS YearsMethod
For 8+ years of data, apply industry-specific loss tolerance. For limited data, every available year must be positive.
Worked Example
This company reported positive earnings in 11 of the last 11 years. The allowed loss tolerance for this industry is 0 years. EPS growth rate (CAGR) is 7.4%.
How to Interpret
Fewer loss years and stronger EPS continuity generally improve confidence in future dividend and valuation assumptions.
A perfect track record through multiple economic cycles means this company generates profits in good times and bad. Your dividend has a solid foundation.

Why It Matters
Revenue trend shows whether the business is expanding or contracting. Debt trend adds context on whether growth is being funded conservatively.
Formula
Revenue Change (%) = (Latest Revenue - Earliest Revenue) / |Earliest Revenue| x 100; Debt Change (%) = (Latest Debt - Earliest Debt) / |Earliest Debt| x 100Method
Map annual revenue history and, where relevant, annual debt history. For financial companies, debt is excluded because deposits and reserves distort this signal.
Worked Example
Revenue changed by +123.7% across the displayed period, while debt changed by +120.3%.
How to Interpret
Rising revenue with stable or falling debt is typically stronger than rising revenue funded by rapidly rising leverage.
Revenue and debt both growing — check whether debt is funding productive growth or covering shortfalls. Sustainable dividends require revenue to outpace debt over time.

Why It Matters
Yield translates dividend income into a percentage of the price paid, which is central to income-first screening.
Formula
Annual Dividends per Share / Stock Price x 100Method
Use the 6-year average annual dividend for consistency and compare the result with the 6% framework requirement.
Worked Example
With a 6-year average annual dividend of $0.18 and a share price of $5.65, the Barsi yield is 3.1%. The minimum requirement is 6%.
How to Interpret
Higher sustainable yield improves upfront income, but unusually high yields may reflect elevated risk or weak coverage.
Low yield means you need significant capital to generate meaningful income. Barsi's strategy focuses on stocks that provide substantial cash flow from day one.

Why It Matters
Payment consistency is a direct test of dividend reliability. Large cuts or skips often appear before confidence recovers.
Formula
Consecutive Years = count of years with dividend payments and no disqualifying skip/cut eventsMethod
Require at least 6 years of history, then check for skipped years and large cuts, allowing approved systemic-event exceptions.
Worked Example
This company has 11 years of dividend history (2016–2026). No suspensions detected — 11 consecutive years of payments. Predictability: Moderate. Payout health: One-off event. The minimum requirement is 6 years.
How to Interpret
Longer uninterrupted records generally signal stronger income reliability than high yield alone.
A 11-year track record through multiple economic cycles gives confidence your income will continue. This company has proven it prioritises shareholder returns.

Current Snapshot

Max Buy Price

Delta
-92.2%
Why It Matters
The price ceiling links valuation discipline to income targets by defining the price that aligns with a 6% yield target.
Formula
6-Year Average Annual Dividend / 0.06Method
Use the 6-year average dividend (not one year) and divide by 0.06 to estimate the maximum entry price for target yield.
Worked Example
With a current price of $5.65 and a ceiling of $2.94, the entry is 92.2% above the ceiling.
How to Interpret
Prices below the ceiling imply a historical yield above 6%; prices above it imply a lower historical yield at entry.
At this price, you won't achieve Barsi's target 6% yield. Consider waiting for a pullback — market volatility often creates more favourable valuations for patient investors.

BESST Match
Yes
Score Impact
+3 points
Why It Matters
Sector classification helps contextualise risk and demand durability, which can materially affect dividend stability.
Formula
BESST Match = Sector in {Banks, Energy, Sanitation, Insurance, Telecom}Method
Match company sector or industry against BESST categories. A match adds scoring support but does not replace core dividend checks.
Worked Example
This company operates in Utilities - Renewable (Utilities sector). It matches the Sanitation category — an essential service sector with stable demand, earning a +3 point scoring advantage.
How to Interpret
BESST alignment is a positive context signal. Non-BESST stocks can still qualify with strong yield and dividend consistency.
Essential services maintain demand regardless of economic conditions - people always need electricity, banking, and telecommunications. Your income is protected by inelastic demand.

How much of a company's earnings are paid out as dividends
The company is paying out more in dividends than it earns (106%). This is unsustainable long-term and often signals a dividend cut ahead. An inflated payout also distorts the price ceiling calculation used in our analysis.

Why It Matters
Payout ratio links dividends to earnings capacity and helps evaluate whether current distributions are likely to remain supportable.
Formula
Payout Ratio (%) = (Annual Dividend per Share / Earnings per Share) x 100Method
Calculate year-by-year payout ratios where EPS is positive, classify each year by sustainability zone, and compare with the current TTM ratio.
Worked Example
$0.08 dividend / $0.23 EPS equals 37.3% payout ratio.
How to Interpret
Ratios in the middle range are usually more sustainable than very high ratios. Values above 100% indicate dividends exceeded earnings in that period.

Why It Matters
CapEx intensity estimates how much of earnings must be reinvested just to sustain operations.
Formula
Cumulative CapEx (10yr) / Cumulative Net Income (10yr) x 100Method
Aggregate 10-year CapEx and net income, then compare the ratio with the sector threshold in the framework.
Worked Example
Over 10 years, 253% of this company's cumulative earnings were consumed by capital expenditure. The utilities & energy infrastructure threshold is 100%, leaving a buffer of -153% (over threshold).
How to Interpret
Lower ratios usually indicate better cash conversion. Higher ratios can reduce room for dividends and buybacks.
High capital intensity means most earnings go back into maintaining the business rather than rewarding shareholders. This is typical for this sector but limits dividend growth potential.

Why It Matters
Debt payoff years converts leverage into an intuitive time measure, making debt burden easier to compare across stocks.
Formula
Long-Term Debt / Average Net Income (3yr)Method
Use current long-term debt and the 3-year average net income to smooth one-off profit noise.
Worked Example
With $2.1B in long-term debt and $204M in average annual earnings (3yr), it would take 10.5 years of earnings to pay off all debt. The utilities & energy infrastructure threshold is 8 years.
How to Interpret
Lower values generally indicate stronger debt capacity. Very high values can constrain dividend resilience.
Higher leverage is structural in this sector, but it means interest payments reduce the pool available for dividends. Monitor debt levels during economic downturns.

Why It Matters
Net income margin shows how much profit the business keeps from each dollar of revenue after all costs.
Formula
Net Income / Total Revenue x 100Method
Compare current margin with the industry-specific threshold to avoid cross-sector distortions.
Worked Example
This company's net income margin is 10.0% — it keeps 10 cents of every revenue dollar as profit after all expenses. The utilities & energy infrastructure threshold is 10%, putting it 0.0% below the requirement.
How to Interpret
Margins that are both strong and stable can indicate competitive strength; persistent weakness may limit reinvestment and payout capacity.
Lower margins in this sector are common, but they leave less cushion if costs rise or revenue drops. Monitor whether margins are stable over time — consistency matters more than the absolute level.

Why It Matters
ROIC measures capital efficiency. Businesses that repeatedly earn above their funding cost can compound value more effectively.
Formula
After-Tax Operating Profit / Invested Capital x 100Method
Use the 5-year average ROIC and compare it with industry WACC plus the required spread in this framework.
Worked Example
This company's 5-year average ROIC is 4.3%, with a cost of capital (WACC) of 6.5%. The -2.2pp gap below WACC suggests it may be destroying value on each dollar invested.
How to Interpret
A healthy spread above WACC suggests value creation; a narrow or negative spread points to weaker capital efficiency.
Returns below the cost of borrowing mean the business destroys value over time. This can erode the foundation that supports dividends — proceed with caution.
