Municipal Bond Arbitrage and Rebates Explained

In the world of municipal bonds, arbitrage is profiting by investing proceeds from low-interest debt into investments with higher rates of return. In accordance with established arbitrage compliance rules (IRC Section 148), you must rebate these profits to the IRS. Failure to comply can result in substantial penalties and even the loss of a bond’s tax-exempt status.

Determining rebate amounts is a multifaceted process that involves calculating a bond’s true yield, allowable earnings and the future value of investment earnings. The risks of taking on these complex calculations yourself and not keeping up with filing requirements is why most local governments seek expert assistance in these matters.

FAQs

What is Arbitrage Rebate?

Arbitrage is earned when proceeds of a tax-exempt or tax-advantaged bond issue are invested above the bond yield, the average yield issuers pay to their bondholders. At its most basic level, this liability to the U.S. Treasury is the excess earnings received from investments when the average rate of return is above the bond yield.

What steps should I take to adhere to Arbitrage Rebate and Yield Restriction Rules?

Keeping quality records is critical to staying in compliance. The IRS requires that issuers maintain a daily transaction detail. Funds invested in established bank accounts will easily satisfy this requirement. Issuers maintaining records separately, on the other hand, should equip data with a running balance that captures deposits, expenditures, and interest earnings by date. Issuers ought to be mindful of IRS-required reporting deadlines upon each new bond issuance. Arbitrage and yield restriction liabilities must be computed at least once every five years from the date of issuance, as well as on the issue’s final maturity date. Arbitrage earnings and yield reduction payments must be paid, or “rebated”, to the United States Treasury within 60 days of each reporting date. Preparation is key. We recommend annual reporting to all of our clients. Completing annual reports has the advantage of allowing the issuer to encumber liabilities in their books and records before a payment is due.

Should I be aware of any exemptions from the rebate requirement?

Yes! There are two major exceptions to arbitrage rebate that every issuer should know: the small- issuer exception and the spending exception. As you may have guessed, the small issuer exception to rebate is based on the size of your debt issuances. Governmental issuers expecting to issue less than $5 million of tax-exempt bonds in a calendar year may be exempt from the rebate requirements. This threshold increases to $15 million for bonds issued to build public schools. The spending exception to rebate is available to issuers meeting certain time thresholds for expending bond proceeds.

The three spending exceptions are the:
1. 6-month spending exception
2. 18-month spending exception and
3. 2-year spending exception

If the proceeds of an issue are invested above the bond yield, meeting a spending exception allows the issuer to keep all of its interest earnings. Who doesn’t love a little extra spending money?
