Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Circuit assemblies rose 125.9% over the last 12 months, more than any of its main inputs. Input costs are not adding pressure right now.

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Printed Circuit Assembly Manufacturing (BLS series PCU334418334418), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Covers the finished assembled board with labor and component cost baked in together. Use this instead of the bare-board index when the supplier delivers a completed assembly, not raw boards.
Split chips from the equipment that makes them. Chip prices index to BLS PCU334413334413, which has trended down over the last decade. Fab equipment indexes to PCU333242333242, which has trended up. A shared index will misprice one side.
Escalake tracks US PPI — Printed Circuit Assembly Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
