GIC vs Structured Treasury Portfolio for Bond Proceeds

Should bond proceeds go into a GIC or a Treasury ladder?

The answer turns on the fund's draw schedule, the bond contract's permitted investments and the compliance work each route carries, not on a rate quote from any single day.

A GIC packages the spending schedule into one negotiated contract with a financial institution; a Treasury ladder holds marketable U.S. Treasury securities the issuer owns, with maturities matched to the same schedule.

GIC or Treasury ladder: which fits which fund?

Neither structure is the automatic fit for any fund type; the choice starts with the fund's spending horizon and expected draw schedule, and the typical horizons GFOA lists show the range.

A GIC builds the draw schedule into the contract itself, through negotiated withdrawal or reinvestment provisions.

A Treasury ladder builds it into the maturities of securities the issuer owns, and faster-than-expected draws are met from a money market allocation held alongside or by selling securities before maturity at the market's price.

GFOA's bond-proceeds best practice lists typical horizons: 12 to 36 months for construction funds, 6 to 18 for capitalized interest funds, usually 6 months for interest accounts and usually 12 for principal accounts, and long term for a debt service reserve fund; for an escrow, the horizon depends on the redemption date.

Those are typical ranges rather than rules, and GFOA directs issuers to their own advisory team and investment policy for the final call.

mGIC evaluates and bids both structures and sells neither, working in the safety, liquidity, yield order: safety first, then liquidity, then yield.

How each structure works

The MSRB glossary defines a guaranteed investment contract as an investment, secured by a contract with a financial institution, that guarantees a fixed rate of return and a fixed maturity.

Bond-proceeds GICs often have flexible draw schedules rather than one fixed maturity, and the tax definition reflects that: Treasury Regulation §1.148-1(b) includes in the term any nonpurpose investment with specifically negotiated withdrawal or reinvestment provisions and a specifically negotiated interest rate, as well as agreements to supply investments on two or more future dates.

The definition's word is "includes", so the list is not exhaustive, and whether a particular agreement falls within it is a bond counsel determination.

The SEC has described municipal reinvestment products as typically financial instruments tailored to meet municipalities' specific collateral and spend-down needs, such as GICs, repurchase agreements and forward purchase agreements (SEC Litigation Release No. 22183).

A Structured Treasury Portfolio takes the other route: the issuer owns marketable U.S. Treasury securities bought with proceeds, with maturities and coupon reinvestment planned around the same draw schedule.

A money market allocation can sit alongside the Treasuries for faster-than-expected spend-down, and mGIC evaluates portfolios structured that way.

STRIPS make the matching precise: TreasuryDirect explains that a fixed-principal Treasury note, bond or TIPS can be split into separate zero-coupon pieces, each paying once at maturity, while bills and floating rate notes cannot be stripped.

TreasuryDirect also notes that a 10-year bond becomes 21 pieces, the minimum face amount is $100, and stripping and reassembly happen only in the commercial book-entry system under 31 CFR 356.31.

Safety: credit, collateral, custody

The safety questions differ because the two structures put proceeds behind different kinds of obligations.

In a GIC, the issuer holds the promise of the provider, and provider credit can come with mechanics that a downgrade triggers.

Ambac's FY2008 Form 10-K reported that its 2008 downgrades triggered cure provisions in nearly all of its investment agreements, that most triggers were keyed to the lower of the Moody's or S&P rating, and that most agreements offered several remedies: collateral posting, termination or a replacement guarantor.

That filing describes one provider's contracts, not market-standard terms.

The same filing said Moody's November 5, 2008 downgrade of Ambac Assurance led to significant collateral posting by its investment agreement and derivatives businesses; it also lists the Lehman Brothers bankruptcy, which gave some counterparties termination rights, as a cause of repayments that shrank its investment agreement portfolio.

State law can add protection against this exposure: Texas Government Code §2256.015 conditions its bond-proceeds GIC authorization on a defined termination date, security of U.S. or agency obligations at least equal to the bond proceeds invested, and a pledge deposited with the entity or a third party it selects and approves; that authorization covers bond proceeds, not general operating funds.

An owned portfolio has no provider promise to monitor, so custody takes the collateral question's place: New York General Municipal Law §11 requires securities bought with bond or note proceeds to be held by a bank or trust company under a written custodial agreement unless they are registered in the local government's own name.

How each state treats the two structures, and what protections a particular issue needs, are matters for bond counsel and the issuer's investment policy, with the state rules page collecting them.

Liquidity: withdrawal flexibility

A GIC's flexibility is whatever its negotiated withdrawal provisions allow, and a Treasury ladder's flexibility comes from the market.

Treasury Regulation §1.148-1(b) builds its definition around specifically negotiated withdrawal or reinvestment provisions, which is what lets a contract follow a draw schedule instead of a single maturity date.

The federal bidding rules tie the solicitation to the same schedule: for a GIC purchase, the terms must take into account the issuer's reasonably expected deposit and drawdown schedule (26 CFR 1.148-5(d)(6)(iii)(A)(5)).

Texas has a parallel statutory requirement: a GIC's price must reflect the reasonably expected drawdown schedule (Tex. Gov't Code §2256.015(c)).

Securities held to maturity pay on their stated dates, STRIPS pay once at maturity, and a portfolio can be repositioned before maturity by selling at the market's price that day.

SLGS sit at the rigid end of the Treasury route: 31 CFR 344.2 bars selling, exchanging, assigning or pledging them, and Treasury cannot call them before maturity.

Common contract withdrawal mechanics are covered on the GIC withdrawals page.

Yield: what sets the rate each one earns

The two prices are made differently: a contract's rate is negotiated when providers bid, and a portfolio's return is assembled from the securities bought and the reinvestment of their payments until the proceeds are spent.

The interest rate on a GIC is specifically negotiated within the meaning of Treasury Regulation §1.148-1(b), and the SEC has said the most common way to establish fair market value is competitive bidding run by bidding agents (Litigation Release No. 22183).

A portfolio's return depends on purchase prices, coupons and what each maturing piece earns when reinvested.

GFOA recommends keeping investment duration no longer than the expected drawdown schedule and revisiting the draw schedule periodically; it also suggests staging bond issues over the construction period and not issuing well before spending begins, to limit arbitrage liability and negative arbitrage.

Both routes face the same ceiling when proceeds are yield restricted: Treasury Regulation §1.148-1(b) defines "yield restricted" as required to be invested at a yield not materially higher than the issue yield, which the yield restriction rules govern.

Longer terms bring in the hedge bond rules, which are written in terms of nonpurpose investments rather than any one product: under section 149(g), summarized in IRS Publication 4079, a bond is a hedge bond unless the issuer reasonably expects 85% of spendable proceeds to be used within 3 years and no more than 50% of proceeds is invested in nonpurpose investments whose yield is substantially guaranteed for four or more years.

Publication 4079 lists exceptions, among them 95% of proceeds invested in non-AMT tax-exempt bonds, or a 10%/30%/60%/85% spending schedule over 1, 2, 3 and 5 years plus payment of 95% of legal and underwriting costs within 180 days.

Whether that test, or any of its exceptions, applies to an issue, and which investments the test reaches, is a question for bond counsel and tax counsel.

Compliance and procurement differences

Both instruments sit inside the same arbitrage framework, but the contract route adds steps of its own, from the GIC questions on the tax forms to the bidding safe harbor.

The contract route also reaches the tax forms: Form 8038-G (line 36) and Form 8038-T (line 30) ask whether gross proceeds were invested in a GIC and who the provider is.

A contract is also the kind of investment the fair-market-value rules watch: Treasury Regulation §1.148-5(d)(6)(i) rebuttably presumes that an investment not of a type traded on an established securities market is not bought or sold at fair market value.

Section 1.148-5(d)(6)(iii) answers with a safe harbor that treats the purchase price as fair market value on the purchase date when its conditions are met, among them a bona fide solicitation, at least three reasonably competitive providers solicited, at least three bids from solicited providers without a material financial interest in the issue, a provider certification of administrative costs, and record retention.

Those conditions are set out on the fair-market-value safe harbor page.

States add procurement conditions of their own, separate from the federal safe harbor: for a GIC to qualify under the section, Texas requires the bond order, ordinance or resolution to specifically authorize GICs, at least three bids from separate providers with no material financial interest in the bonds, purchase of the highest-yielding qualifying bid, a price reflecting the expected drawdown schedule, and provider certification of administrative costs (Tex. Gov't Code §2256.015(c)).

Texas also caps a bond-proceeds GIC at five years from the bonds' issue date, except for reserves and funds maintained for debt service purposes (§2256.015(b)).

The Treasury route rides general authorizations for U.S. obligations, such as §2256.009(a)(1) in Texas, but state conditions on bond-proceeds investments still reach it, like New York's rule that obligations bought with bond or note proceeds be payable or redeemable at the owner's option within two years of purchase.

Which instruments are even on the table comes from the bond documents: the MSRB glossary defines permitted investments as the instruments in which bond proceeds or other funds may be invested under the bond contract, so that contract is where the list lives; see a bond indenture or authorizing order.

An independent Bidding Agent can solicit qualified providers and compare bids on your proceeds under either structure; mGIC performs that role without selling either product.

Decision table

The table collects the differences between the two routes for a given fund.

Final determinations about which structure an issue may use, and how each is treated under the arbitrage and state rules, belong to bond counsel and tax counsel.

If both structures should be priced against the same draw schedule, mGIC can run that comparison as a free, no-obligation reinvestment review.
