Basis: tangible common book. Dividends are reinvested at book value.
No decline detected by the published slope-ratio test.
Method, filing sources and publication receipt
The compounder rule requires a top-decile composite, positive slope and no detected decline in the tangible-book eligible pool. Total-common-book fallback rows cannot qualify. Decline means the 90% interval for recent / whole-window slope lies below 1.
Source: SEC first-filed XBRL. Midas Edge API’s published Green Compounders method uses only filings public by the as-of date, split-adjusted shares and the original filed values. Restatements do not replace them. Issuer pools and entity types reflect the SEC submissions captured for this run, not historical classifications at each as-of date.
The primary form fits log book value with reinvested dividends against time. The method checks the starting book and market-cap floors and excludes identified non-reliance/enforcement windows. Its cohort is fixed at capture time, so historical percentiles have capture and survival limits. It does not check audit-opinion going-concern text. This grade is separate from InsiderIQ, HolderIQ and NetCredibility.
Input filings (21 in this window): 0000834365-25-000016; 0001437749-21-020183; 0001437749-21-026719. The links show up to three of the input filings.
Method notes: Going-concern audit wording was not evaluated. An additional method qualification is recorded in the publication receipt. Missing dividend facts were treated as zero by the published method. Enforcement findings use records naming the issuer.

How this is measured
A connection is distinguishable from zero here only when its RED or GREEN published interval has a lower bound above zero. A person with an admitted finding is always listed first, even with a zero score. Connections are then ordered by the larger of RED and GREEN. A zero tied with other owners is not given a percentile.
RED measures graph connections to people with admitted adjudications; GREEN measures connections to repeat value creators and stewards of qualifying compounders and long-term shareholder-return leaders. Net is GREEN minus RED on a −1 to 1 scale, not a probability or expected return. Connections alone do not establish conduct. These measures are separate from insider trading performance and Company Quality Grade.
The publication is uncalibrated. Its intervals are published bands, not a claim of calibrated confidence or a tested forecast.
Admitted findings are published guilty pleas, convictions and litigated SEC judgments or orders. Settlements and open cases are not findings. A positive net does not erase an admitted finding. Absence of a finding is not a clearance or a complete regulatory-history search.
Reporting owners who filed from after Oct 9, 2025 through Oct 9, 2026: a 12-month window ending at the publication date. This can include former officers and directors; it is not a verified roster of today's employees.
Link an account to see your stake, watchlist and past holdings. use the cited filings to check the reported role and evidence alongside your investment thesis. A connection alone does not tell you to increase or reduce a holding.
Medians across all 17 scored reporting owners at this company as of Oct 9, 2026: RED 0, GREEN 0, net 0. Highest RED: 0; highest GREEN: 0.

Link an account to see your stake, watchlist and past holdings. Compare cash generation and investment needs with your thesis. Working capital and non-cash charges can separate profit from cash. Capital spending can reduce free cash flow while earnings rise. For a long or short position, that gap alone does not predict a price move.
Cash-flow source and meaning
Source: Annual financial statements, latest stored vendor-normalized figures. These may include restatements and may differ from the filer’s own XBRL. A filing date is not the knowledge date of this version of the values.
Free cash flow is the vendor’s reported figure, shown only when it agrees with operating cash flow less capital spending recorded as a positive outflow. It is not cash guaranteed for dividends or buybacks, and it does not subtract every financing obligation. Missing or sign-incompatible inputs are not filled in. An unlabelled currency is used only for a confirmed domestic USD filer. These are annual statements, not forecasts or an originally-filed history.
Cash allocation: dividends, shares and debt
Where did BLFS’s financing cash go? Compare cash paid as dividends with net share and debt transactions across fiscal years. Amounts are in USD, the reporting currency. These are company-wide totals, not per-share payouts.

Link an account to see your stake, watchlist and past holdings. Compare these uses of cash with operating cash generation and the debt on the balance sheet. A negative net share movement means purchases exceeded issuance; it does not give gross buybacks. A dividend or share purchase can be financed with borrowing, and none of these flows guarantees a future payment or price return.
Allocation source and sign conventions
Source: Annual cash-flow statements, latest stored vendor-normalized values for the same security and fiscal year. These can include restatements; a filing date is not the knowledge date of this version.
Dividends are positive cash paid out. For net share transactions, net borrowing and total financing, positive means cash in and negative means cash out. Net share transactions combine issuance and purchases; they are not gross repurchases, a change in shares outstanding, or stock compensation. Total financing includes other flows and is not the sum of just these three lines. Zero means a reported zero. No FX conversion, shareholder-return total or forecast is inferred.

Change = this settlement’s shares short − the previous recorded settlement’s shares short; percentage change divides by that earlier count. A zero earlier count has no percentage change. Split-spanning counts are left uncompared. Float percentages use the stored settlement observation, not today’s float.

Cash bars retain the event's recorded currency and share basis. The yield line divides recorded cash in the preceding 365 days, adjusted for intervening splits, by a verified raw close in the same currency. Special dividends are included. Future ex-dates are excluded from yield. A split changes share count, not investment value. For long shares, past entitlement depends on when you held them; short shares can create a dividend payment obligation.

Moves the factor model did not explain
How much of BLFS’s move accompanied the market and its measured style leanings, and how much was left? The residual is unexplained by this fitted model. It does not establish a cause, skill or future alpha.
Return split unavailable. A complete, reconciled model for every market session in this window is unavailable. Missing dates are not filled.
Link an account with dated transactions to see what share of your own holding’s move since its purchase-date close was unexplained, with long and short positions distinguished. Your private holdings never enter this public chart.

How this split is calculated
Each day uses that day’s fitted market intercept and style exposures multiplied by that day’s published factor returns. Their sum plus the independently stored residual must reconcile to the stock return. Window effects are weighted by stock wealth at each day’s start and added; the stock return compounds. Every expected US market session must be present and pass source, identity, model and numerical checks. This retrospective fit is an explanation of measured returns, not evidence of causation or an investable forecast. The window ends at the latest published model session, which can lag the market; today’s unfinished session is excluded.
