What the awards don't tell you about DON H. MAHAFFEY DRILLING CO.

A registration tells you DON H. MAHAFFEY DRILLING CO. exists. It does not tell you whether the company is solvent, who controls it, whether a lender holds a charge over its assets, or whether it has been sued. The report checks each of those and names every source it checked, including the ones that came back clean — for DON H. MAHAFFEY DRILLING CO. that means active ucc liens, secured lenders and competitors in construction, itemized with the filing behind each fact.

How this differs from a credit report

They get bought for each other and answer different questions. If yours is the first one below, buy the credit report — it does that better than we do.

The questionA traditional
credit report
A MiMi dossier
Will they pay my invoice in 30 days?YesNo
Payment behaviour & trade referencesYesNo
A credit score and recommended limitYesNo
Registered identity & addressYesYes
Insolvency, liquidation, strike-offYesYes
Secured charges & liens, by lenderSometimesYes
Litigation, each case linked to its docketNoYes
Debarment, exclusion, termination for defaultNoYes
Public-contract award history & who boughtNoYes
Owner graph — what else the principals controlSometimesYes
A written assessment framed to your decisionNoYes
Every claim traceable to the filing behind itNoYes

A credit report tells you whether to extend terms. A dossier tells you whether to enter the relationship at all — and what to verify first. We publish no score, because a rating is our judgement to defend and a filing is simply true.
