How the derivatives safe harbor engineers the value a failing firm must survive
J. Schidzig · Legal Quant
The U.S. Bankruptcy Code lets derivative counterparties do at a filing what every other creditor is barred from doing: terminate, net, and seize collateral at once. Read across the rulings since Lehman, that safe harbor moves value in one direction so consistently that the arrangement has the shape of an engineered outcome.
The paper runs in two registers. The doctrinal half traces where the value goes. The methodological half answers what doctrine cannot: what simultaneous close-out does to a coupled system under stress. A stochastic engine switches the harbor off, then on, and recovers its contribution to the downside as the difference between the two runs, not as an assertion.
Figure 1. The dashed curve is the firm with the safe harbor absent (θ=0); the solid curve is the same firm with the harbor in force (θ=1), everything else held identical. The shaded band below the liquidation floor is ΔH, the value the safe harbor relocates out of the estate, recovered as the difference between the two runs rather than asserted.
The same distribution is read two ways in one case: at plan confirmation the downside mass is a liability the debtor must show is small; at DIP-financing approval the same mass is the justification for the loan. One object, two procedural questions, which is how the method carries legal weight rather than legal preference.
