LAIF and Bond Proceeds: When a Competitively Bid Investment Earns More

Whether a California issuer should keep bond proceeds in the Local Agency Investment Fund depends on what the money is waiting to do: Government Code §16429.1(d) lets an agency, with its governing body's approval, deposit proceeds of bonds, notes, certificates of participation or other evidences of indebtedness in LAIF pending expenditure.

What a deposit does not settle is the rate question: LAIF apportions earnings quarterly from a commingled pool at a yield no provider has bid for the issuer's fund.

What is LAIF and who can invest in it?

LAIF is a voluntary investment program created by statute in 1977, administered by the California State Treasurer and invested as part of the Pooled Money Investment Account (PMIA), under Government Code §16429.1 et seq.

Its securities are bought under Gov. Code §§16430 and 16480.4, the Pooled Money Investment Board provides oversight, and the Local Investment Advisory Board oversees LAIF.

The fund is open to local governmental units, nonprofit corporations whose membership is confined to public agencies or public officials, and qualified quasi-governmental agencies, under Government Code §16429.1.

Once deposited, §16429.3 shields the money from state transfer, loan or impoundment, and §16429.4 says withdrawal on demand cannot be impaired because the state has failed to adopt a budget.

For bond proceeds, §16429.1 lets LAIF deal directly with the agency's trustee or fiscal agent, the Controller keeps a separate account for each deposit of proceeds, and §16429.1(f) leaves the length of the deposit to that trustee or fiscal agent alone.

LAIF is a commingled subset of the PMIA rather than a standalone fund, and its June 30, 2026 Information Digest states that the pool is not rated, is not a 2a7-like external investment pool, and is valued by amortized cost and current value methods.

How is LAIF's yield set, and how has it moved?

No rate is set for an individual account: earnings are apportioned quarterly in proportion to amounts deposited and time on deposit, so how the yield has moved is read from the Treasurer's published series rather than a number fixed for one fund.

The Treasurer publishes the PMIA daily effective yield and LAIF quarterly apportionment rates online, and the LAIF page links to the daily file, the quarterly table and monthly averages.

Because the apportionment resets quarterly, a multi-year hold earns the sequence of quarterly rates across its holding period, not one number locked in at closing.

Government Code §16429.1 caps administrative costs at 5% of quarterly earnings, or 8% for the following fiscal year if the 13-week Daily Treasury Bill Rate is below 1% on the last day of the fiscal year, a ceiling rather than the charge.

The bid side moves daily, and mGIC posts today's reinvestment rates with a rate-update email each business day covering Treasury yields, SOFR and SLGS.

How the pool-level apportionment compares with a rate bid, alongside credit, collateral and custody, is the LGIP vs GIC comparison.

How do arbitrage and rebate rules track proceeds held in a pool?

A LAIF deposit is an investment of the issue's proceeds, so both federal arbitrage rule sets follow the money: IRS Publication 5271 treats yield restriction and rebate as independent tests, and an issuer can satisfy one and still hold arbitrage bonds for failing the other.

Where proceeds are yield restricted, the general test applies: for investments not otherwise described in the regulation, Treasury Regulation §1.148-2(d)(2)(i) treats an investment yield as materially higher than the bond yield when it exceeds the bond yield by more than one-eighth of 1 percentage point.

How long a construction fund's temporary period runs is the first question, because §148(c)(1) lets proceeds earn above the bond yield for a reasonable temporary period, and the temporary periods page works through each one.

A temporary period lifts yield restriction only: Publication 5271 notes that even when yield restriction permits above-bond-yield investing, the rebate rules may still require those earnings to be paid to the United States, and rebate generally applies to temporary-period earnings unless a rebate exception applies.

The rebate amount is the excess of the future value of all receipts over the future value of all payments, compounded at the bond yield, under §148(f)(2) and Treasury Regulation §1.148-3(b) to (c), and any earnings the LAIF account produces enter as receipts on nonpurpose investments.

Where rebate applies, the schedule is the same wherever the money sits: §148(f)(3) and Treasury Regulation §1.148-3(f)(1) require the first installment to cover a computation date no later than 5 years after the issue date and each later one no later than 5 years after the prior.

Each installment must bring cumulative payments to at least 90% of the rebate amount at future value, and every payment is due within 60 days after its computation date.

The pool's own Digest describes the bond proceeds accounts without mentioning yield restriction or rebate, so the federal tracking stays with the issuer and its tax counsel; what pool documents generally leave to the issuer is covered on our local government investment pools page.

What liquidity does LAIF give compared with a draw-matched agreement?

LAIF credits a transaction completed by 10:00 a.m. the same day, while a competitively bid agreement matches withdrawals to a draw schedule the provider has priced before closing.

A regular account is capped at $75 million and allows 15 transactions a month, each between $5,000 and $75 million in $1,000 increments, according to the June 30, 2026 Information Digest and procedures page, limits that are set administratively and can change.

LAIF asks for one day's notice on deposits or withdrawals of $10 million or more, credits transactions completed by 10:00 a.m. the same day, and lets a transaction be scheduled up to 10 calendar days ahead.

The bond proceeds account works differently: it takes a one-time deposit with no cap, carries no minimum or maximum balance, runs on a monthly drawdown schedule, and closes automatically at zero, where regular accounts stay open.

On the bid side, the bidding safe harbor in Treasury Regulation §1.148-5(d)(6)(iii)(A)(5) requires a GIC solicitation to reflect the issuer's reasonably expected deposit and drawdown schedule, so withdrawals are priced before closing; the withdrawal provisions page covers the contract terms.

When does a GIC, flex repo or Treasury portfolio beat LAIF?

No structure wins on rate in the abstract: the comparison turns on how long the balance stays invested, how predictable the draws are, and whether the issue can invest above its bond yield during a temporary period.

What a bid adds is a price test: Treasury Regulation §1.148-5(d)(6)(i) rebuttably presumes an investment not traded on an established securities market was not bought or sold at fair market value, which is why GICs and escrow portfolios rely on the bidding safe harbor.

The safe harbor in §1.148-5(d)(6)(iii) treats a GIC's purchase price, or that of an investment bought for a yield-restricted defeasance escrow, as fair market value when all its requirements are met: a bona fide solicitation, qualifying bids, the winning-bid rules, a provider certification of administrative costs and record retention.

Failing a requirement costs the presumption rather than proving the price unfair, and the full-flex repo and structured Treasury portfolio pages cover how those products are built.

Whether a product can be bought is a state-law and bond-document question: §53601(m) provides that money held by a trustee or fiscal agent and pledged to bonds, lease or installment-sale obligations or COPs may be invested under the statute governing that issue, and where that statute is silent, or to the extent consistent with it, under the ordinance, resolution, indenture or agreement providing for the issue.

Government Code §5922(d) likewise lets bond proceeds and pledged money be invested in securities or obligations described in the bond documents, and the words "guaranteed investment contract" appear nowhere in §5922, so what an indenture authorizes is a reading for bond counsel.

For money the treasurer holds outside those trustee and bond-document provisions, which statute governs is also a reading for bond counsel: §53601 covers a city, district or other local agency that does not pool money with agencies that have separate governing bodies (§53635 governs agencies that do), lists what it may buy with sinking fund or treasury money not needed immediately and, unless the section itself says otherwise, bars securities with more than five years to maturity absent express authority from the legislative body granted no less than three months before the investment.

The list authorizes U.S. Treasury notes, bonds and bills under (b) and caps mutual funds and money market funds together at 20% of the agency's investable money under (l), and its current text is repealed on January 1, 2031.

The rest of California's list is on the California permitted investments page.

Can an issuer use both: a pool for near-term draws and a bid for the rest?

Using both is a question for the bond documents and bond counsel: the permitted-investment language must accommodate a pool account and a bid agreement, and the safe harbor analysis runs on the bid piece.

The bid piece is where a Bidding Agent works: specifications, soliciting qualified providers, comparing bids on rate and non-rate terms, and certifications at settlement, with the fee paid by the winning provider.

Where a fund has sat in LAIF for a while, a reinvestment review can compare your pool yield with real bids before anything is restructured.

mGIC is an independent municipal advisor and Bidding Agent that sells no investment product and acts as no principal; a conversation about a fund starts with a free, no-obligation reinvestment review.

Final conclusions about what an issue may buy and what the arbitrage rules require belong to bond counsel and tax counsel.
