Variable Rate Demand Obligations – that’s right, Variable Rate Demand Obligations, or “VRDOs”. To most investors, the name is entirely “Greek” as is the nature of how the instruments work. But VRDOs represent a holdings play generating a hugely important yield component in municipal money market funds as well as for many institutional cash managers. And, since November of 2007, they’re also available via an ETF structure.
VRDOs are nothing new. In fact, VRDOs have been around since the early 1980s and presently comprise roughly $500 billion of municipal bond issues (according to PowerShares, April 2009).
So why haven’t most individual investors heard about these long ago? VRDOs aren’t common kitchen-table talk topics in most homes or, for that matter, in most investment advisory shops.
First, at $100,000 per unit, VRDOs are not “pocket change” to most investors. Secondly, the fact that liquidity is available only weekly and only via the exercise of a put option makes VRDOs very much a “hands-on” cash management tool requiring more touch and attention than most investors and advisors are accustomed to. Further, advisors themselves generally just don’t have a good understanding of what VRDO instruments are, how they work or related risks.
So how can VRDOs be of interest to investors using ETFs? VRDO ETFs can serve as an attractive source of tax-exempt income in a form that has demonstrated a highly stable NAV through some pretty challenging times since the launch of PowerShares’ PVI in November 2007. And the industry’s second VRDO ETF, State Street’s VRD, came to market just last month.
Let’s take apart a VRDO to get a sense as to how these instruments work and the characteristics they impart to an ETF.
VRDOs are fixed, long-maturity bonds – typically thirty to forty years – and are issued by municipalities. But VRDOs carry a put-option feature that allows the holder to put the bonds back to the issuer, or a surrogate liquidity provider, at par plus accrued interest. Most VRDOs have a 7-day put feature, meaning that the instrument can be put back to the issuer or liquidity provider on a weekly basis (with typically up to five business days for settlement following exercise).
The definitive put feature enables classification of VRDOs as short-term debt or cash instruments by their holders. This important aspect makes VRDOs eligible for holding in most tax-exempt money market funds where, consequently, they represent an important yield component.
Yields for 7-day VRDOs are reset weekly according to indexes maintained by the Bond Marketing Association.
For municipalities, the attraction of VRDOs is that they enable long-term debt to be financed at short-term rates. The trade-off for municipalities is the taking on of floating-rate risk and the specter of higher interest rates.
As a practical matter, most municipalities are not operationally well-disposed to manage the ebb and flow of VRDO holders’ exercise of puts and the ensuing need to resell the previously put-tendered VRDOs. Accordingly, most VRDOs are wrapped with a liquidity assurance supported by a bank-issued letter-of-credit to ensure return of principal plus accrued interest for holders following the exercise of VRDO puts. Many long-term municipal bonds – including many VRDOs – are also insured against default.
As with all debt instruments, there are liquidity and credit risks to holders of VRDOs which, in the end, could compromise a holder’s ability to recoup interest and principal from the issuer or the market.
VRDO provisions typically enable the immediate retraction of the liquidity put feature by the provider of the bank-issued letter of credit when the rating of the issuer (or, if the issuer is insured, the higher rating of the municipality or its insurer) drops below investment grade (BBB-/Baa3).
Declines in issuer (or insurer, if applicable) to levels below (typically) AA/AA2 or AA-/Aa3 can also trigger a retraction of the put feature but typically only after a 30-day notice period during which time holders may put the bonds to the liquidity provider.
Consequently, the greatest liquidity and credit risk to a VRDO holder would tend to be associated with a rapid plunge in rating of the issuer (or insurer, if applicable) to below investment grade – causing the bond to behave as a non-investment grade, long-maturity debt instrument with yields still reset weekly at short-term rates.
Since the spring of 2008 the Federal Reserve and Treasury have taken steps to enable liquidity providers to pledge many VRDO securities as collateral – greatly reducing liquidity risk for banks providing liquidity wrap features to VRDOs.
As of October 2, PowerShares PVI held $1.02 billion in assets spread across 127 holdings. PowerShares reports that “PVI’s NAV has stayed within a range of $24.97 to $25.10 from its inception through May 2009” while maintaining “an average price spread of $.01, putting it on a par with some of the most liquid securities in the market today.” The 30-day SEC yield on October 2 was 0.80% (roughly 1.23% taxable equivalent yield for a 35% federal income tax bracket).
PVI’s expense ratio stands at 0.25% while State Street’s VRD clocks in at 0.20%.
Glass half full? … What you see is what you get but what about what you don’t see?
Municipal VRDOs represent a great innovation that has, so far, withstood severe market stresses of the current crisis as well as recessions and market shocks of the past nearly thirty years. However, the challenges faced by municipal bond markets today are arguably more acute than at anytime during all of our lifetimes.
Full disclosure of ETF holdings on a daily basis provides a clear picture of the VRDO bonds held in PVI or VRD. This is an important advantage relative to the severely lagged reporting on holdings in money market mutual funds where publishing of holdings is quarterly and up to sixty days in arrears. What you see, holdings-wise in the ETF, is what you get. What you see in the money market fund holdings disclosures is what you had at a single point in time, sometime between three months ago and five months ago.
Quite unfortunately, what you won’t currently find in money market fund disclosures or in VRDO ETF literature is a description of holdings by provider of liquidity support or by bond insurer. Prospectuses do, in their statements of risk, highlight the fact that insurers are relatively large and concentrated such that financial trouble with one or more of these large institutions could have an adverse impact on holdings in the fund. Disclosures of a similar kind are noted in regards to VRDO liquidity providers. And yet, in fund descriptions, single bond and VRDO holdings are listed but distribution and concentrations across liquidity providers and credit insurers are not, even though these are acknowledged to exist and to constitute a material source of risk.
In the end, position disclosure by ETFs is significantly better than what is generally provided by municipal money market funds. And, for that reason, PVI or VRD can make a very solid case, for the sake of clarity and (at least partial) peace of mind, relative to municipal money market mutual funds. As with other holdings, including money market funds, moderation is the key.
