What it makes you produce

2 items for your checklist, slowest first.

  1. Something you write

    Days to weeks, and nobody outside your company has to agree to it.

    • Written notice to the administrative contracting officer within 30 days of a change in ownership or control that could move the valuation of capitalized assets, and a second notice within 30 days of learning what it does to asset valuation and cost

      FAR 52.215-19(a)(1) and (a)(2)

  2. Nothing to send now

    It does not hold the order. It decides what money moves later — what you can claim, what can be claimed from you, and what can be held back — and none of that changes after signature.

    • The pre-change asset and depreciation records, held open to the administrative contracting officer on demand

      FAR 52.215-19(b)

When it is used

Enters the prime's contract when certified cost or pricing data or cost determinations subject to subpart 31.2 are contemplated (15.408(k)). Flows down to subcontracts with the same applicability. Operative when there is an ownership change that could alter the valuation of capitalized assets (sale, merger, acquisition).

Read closely

Anyone planning a sale or a merger with a live cost-type contract meets this at the deal checklist rather than at closeout, and 30 days is short for a transaction nobody flagged in advance.

This is research, not legal advice. It states what the regulation says about this clause and cites the paragraph behind it. It does not rule on your order, and it does not rule on whether a prime's markings are correct.
