5 years of fundamentals
The business, in plain English
TANKE BIOSCIENCES CORP booked $28.6M of revenue in FY2012 in the Consumer Staples sector and kept 34.8% of it as gross profit — a moderate-margin business by that measure. After every other cost, −0.7% of each revenue dollar reached the bottom line.
It earned 25.3% on invested capital in the latest filed year, FY2012. Across the full 3-year measurable filed record, median ROIC was 25.3%. Over the v3 recent window (3 measurable filed years), median ROIC was 25.3%. The Returns on Capital filter above scores it 100/100.
The balance sheet carried $2.1M of total debt in FY2012. Balance-Sheet Safety scores it 58/100.
Put together: Returns on Capital is the strongest of the five filters (100/100) and Capital Allocation the weakest (24/100), which is how TNBI lands at 59/100 — a Shallow moat.

Insider activity
Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”
These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.
This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.
