Don’t discount ZDB just yet

February 22, 2016 - 2 comments

In February 2014, BMO released a more tax-efficient version of their flagship BMO Aggregate Bond Index ETF (ZAG). They called their new fund the BMO Discount Bond Index ETF (ZDB). The fund’s strategy was to buy Canadian government and corporate bonds that were trading at par or at a discount to their par value (for a more detailed discussion of ZAG vs. ZDB, please refer to Dan Bortolotti’s blog post, New Tax-Efficient ETFs from BMO). By purchasing lower coupon bonds, the ongoing interest received would be lower than traditional bond ETFs, resulting in a relatively lower tax liability for taxable investors). Clever strategy in theory, but let’s see whether this more tax-efficient structure actually worked out for investors.

The Results

Using my after-tax rate of return calculator, I’ve compared the returns of five plain-vanilla broad market bond ETFs that were available during the entire 2015 tax year. Before-tax, ZDB returned 3.60%, placing it in first place. After-tax, ZDB maintained its first place ranking, returning 2.52%. Its 2015 tax cost ratio (which is similar to a management expense ratio, but for taxes paid instead of management fees paid) was also the lowest of the group, at 1.04%.

In the chart above, it is also interesting to note that only $184 million is currently invested within ZDB (which is less than 5% of the total assets under management of all five bond ETFs). Hopefully this analysis will help to alert investors and their advisors to more tax-efficient alternatives to their current fixed income picks.

@Anne - you are correct. If an investor is comfortable with the counterparty risk of a swap structure, HBB would likely be more tax-efficient than ZDB.

HBB’s different tax structure and counterparty risk makes any comparison difficult. The closest you could get is to calculate a post-liquidation return for all ETFs (i.e. assume that each one is sold at the end of the 1-year holding period). I would estimate that HBB would come out slightly ahead of ZDB post-liquidation (by about 0.22%).

HBB is also a tax efficient option for bonds in a taxable acct. Assuming one is comfortable with the swap set up with National Bank, how would HBB compare with ZDB? Thanks.
