Shares published in previous semesters

The issuer publishes a new share every semester. For a capital gain, the share of the semester in which the SALE took place applies — not today's.

How it works

iShares $ Treasury Bond 20+yr UCITS ETF is invested almost entirely in «white-list» government bonds (96.35% share): nearly all of the capital gain is taxed at the reduced rate, and the 12.99% effective rate is close to the theoretical 12.5% minimum. Typical of government-bond ETFs.

In Italy, ETF capital gains are taxed at 26%. But the portion of the fund invested in Italian and «white-list» government bonds enjoys the reduced 12.5% rate. The effective rate is therefore a weighted average of the two, based on the share of government bonds the fund holds — a share each issuer certifies every semester as the average of the last two reports.

Worked example

Amounts are purely illustrative: the computation applies this fund's effective rate. The same share applies to capital gains and distributions.

You sell with a €1,000 capital gain
€963.50 on the white-list portion (12.5%) → €120.44
€36.50 on the rest (26%) → €9.49
Tax:€129.93without the white-list share it would be €260.00
you save €130.07
You receive €100 in distributions
€96.35 on the white-list portion (12.5%) → €12.04
€3.65 on the rest (26%) → €0.95
Net in your pocket:€87.01without the white-list share it would be €74.00
you save €13.01
