Please note that Table 1 contains three errors in the total row. The correct total for Resources portfolios is 81, the total for Social portfolios is 136, resulting in a table total of 257. This correction of the total number of portfolios (257) should be extended to the text on pages 6-8 where the total 255 was originally used.

The value of 55 on the y-axis of Figure 3 should read 25.

A higher resolution copy of Figure 2 without overlap on the provincial label markers can be obtained from the authors.

The authors regret the error.
