### 1. *Estate of Woelbing v. Commissioner*

#### Transaction Background
In 2006, H.A. Woelbing sold non-voting stock in a closely held operating company (valued at $59M) to an IDGT in exchange for a 12-year promissory note bearing interest at the Mid-Term AFR (4.63%). The trust was seeded with personal guarantees from adult beneficiaries equal to 10% of the note value, but possessed minimal independent cash equity.

#### IRS Audit Position & Notice of Deficiency
Following Mr. Woelbing's death during the note term, the IRS issued a deficiency notice asserting:
1. **IRC § 2036 & § 2038 Estate Inclusion**: The IRS argued the promissory note was not bona fide debt because the trust lacked independent cash equity. Thus, the IRS claimed the transaction was a transfer with a retained income interest, requiring **100% of the stock ($59M + growth) to be included in Mr. Woelbing's taxable estate**.
2. **IRC § 2702 $0 Valuation**: Alternatively, the IRS asserted the note was an invalid retained interest under IRC § 2702 valued at $0, triggering a **$59M immediate taxable gift**.

#### Case Outcome & Settlement Lessons
The case settled in 2016 with **zero § 2036 estate inclusion** and zero gift tax deficiency, but highlighted critical operational lessons:
- Relying solely on beneficiary guarantees without actual liquid seed cash increases audit scrutiny.
- Seeding an IDGT with at least **10% independent cash or liquid assets** prior to the sale is essential to withstand IRS scrutiny under §§ 2036, 2038, and 2702.

### 2. *Estate of Davidson v. Commissioner*

#### Transaction Background
William Davidson (former owner of the Detroit Pistons and Guardian Industries) engaged in a series of installment sales of private company stock valued at over $900M to IDGTs in exchange for **Self-Canceling Installment Notes (SCINs)**.

#### IRS Audit Position
The IRS asserted over **$2.8 Billion in estate, gift, and generation-skipping transfer tax deficiencies**, arguing that:
- The SCINs were not bona fide debt obligations because Mr. Davidson's health made full repayment unlikely.
- The trust lacked sufficient independent equity to support the note obligation independent of dividends from the transferred stock.

#### Audit Takeaways for IDGT Note Sales
1. **Commercial Terms**: Promissory notes must bear market AFR interest rates and fixed repayment terms.
2. **Independent Solvency**: The purchasing trust must maintain independent equity (10%+ seed) so note payments are not solely dependent on distributions from the sold asset.
3. **Strict Note Administration**: Interest and principal repayments must be executed meticulously on schedule via documented bank transactions.
