Glossary of Key Terms

Adjusted basis
The seller's cost in the asset adjusted for improvements and depreciation; recovered tax-free as payments are received.
Assignment company
A specialized, non-insurance entity that accepts the buyer's payment obligation via a non-qualified assignment and funds it with an annuity.
Claims-paying ability
An insurer's financial capacity to meet its policy obligations, as assessed by rating agencies.
Constructive receipt
A doctrine taxing income once it is made available; an SIS seller must not have a present right to the full proceeds.
Contract price
Selling price reduced by qualifying assumed debt (not exceeding basis); the denominator of the gross-profit percentage.
Deferred Sales Trust (DST)
A strategy in which sale proceeds are placed in a third-party trust that invests them and pays the seller over time under an installment contract. Distinct from an SIS (no trust) and from a monetized installment sale (no loan); aggressive forms draw IRS scrutiny.
Economic-benefit doctrine
Rule taxing funds irrevocably set aside for a taxpayer; the SIS seller must not own the funding annuity.
Gross-profit percentage (GPP)
Gross profit ÷ contract price; fixes the taxable-gain fraction of each installment payment.
Installment method
IRC §453 method of reporting gain proportionally as payments are received.
Listed transaction
A transaction the IRS has identified as potentially abusive; a properly structured SIS is not one.
Monetized installment sale
An arrangement combining installment deferral with a near-term loan against the note for cash now; targeted by the IRS (REG-109348-22) and DOJ. Distinct from a Deferred Sales Trust (which uses a trust, not a loan) and from a bona fide SIS.
NIIT
The 3.8% Net Investment Income Tax (§1411), applying above MAGI thresholds of $200K (single) / $250K (MFJ).
NOLHGA
National Organization of Life & Health Insurance Guaranty Associations, coordinating state guaranty coverage.
Non-qualified assignment
Transfer of a payment obligation outside §130 (which requires physical injury); the legal engine of the SIS.
Pledge rule (§453A(d))
Treats amounts borrowed against an installment obligation as payments received, triggering immediate gain.
Recapture (§1245 / §1250)
Prior depreciation recaptured on sale; §1245 is ordinary income in year 1, unrecaptured §1250 is taxed at a 25% maximum.
Risk-Based Capital (RBC)
NAIC formula scaling required insurer capital to risk; triggers a four-level intervention ladder.
Statutory Accounting Principles (SAP)
Conservative, solvency-focused accounting required of insurers, more stringent than GAAP.
§453A interest charge
Annual interest on deferred tax when sale price exceeds $150,000 and obligations exceed $5,000,000 at year-end.
§453B disposition
An event accelerating installment gain; a mere substitution of obligor, rights intact, is not one.
Structured settlement
Periodic-payment resolution of a physical-injury claim under §104(a)(2)/§130 — the precursor to the SIS.
