How to read the effective license position.

The effective license position is where the audit becomes a number. Learn how IBM builds the ELP, where the errors hide, and which lines a buyer side review challenges first.

When IBM presents findings, it presents an effective license position, usually called the ELP. In plain terms it is one subtraction: what you are entitled to, minus what the tooling says you deployed. A positive balance is surplus. A negative balance is the compliance gap IBM will ask you to pay for. The whole audit comes down to how each side of that subtraction was built.

The two sides of the equation

The entitlement side is drawn from Passport Advantage records and proof of entitlement documents. The deployment side comes from the data collection tool. Auditors tend to present the gap as settled arithmetic, but both inputs are assembled by people making judgement calls, and both are routinely understated or overstated.

The deployment side is usually the larger problem. PVU values can be wrong for the processor type, sub capacity can be denied where it should apply, and bundled components can be counted as full standalone products. The entitlement side is its own battle: IBM frequently omits entitlements you actually hold, especially older perpetual licenses, migrations, and entitlements absorbed through an acquisition.

Where the errors hide

• Wrong PVU per core. The position assumes a processor rating. If an Intel core is rated at the wrong value, every server with that chip is mispriced.
• Sub capacity denied. If the tool data has a gap, IBM applies full capacity to the whole host. Restoring the sub capacity claim can cut a single line by an order of magnitude.
• Bundled use treated as standalone. A Db2 engine bundled inside Cognos counted as a separate Db2 deployment is a classic over count.
• Missing entitlement offsets. Licenses you own but IBM did not credit reduce the gap directly when you produce the proof.

How a buyer reads it

Read the ELP line by line, never as a total. For each product, ask three questions: is the PVU rating correct for the hardware, is sub capacity being applied where it is eligible, and has every entitlement we hold been counted. Most of the recoverable value sits in those three questions. On average, a disciplined challenge lands 30 to 50 percent of the findings, and in the strongest cases the reduction runs much higher.

The ELP is a spreadsheet, and spreadsheets carry the assumptions of whoever built them. Your job is to surface those assumptions and put evidence against each one before you discuss a settlement number.
