This is from Q1 report:
"Portfolio investments comprise investments carried at fair value and equity accounted investments, the aggregate carrying value of which was $37,867.5 ($37,435.3 net of subsidiary short sale and derivative obligations) at March 31, 2020 compared to $38,235.0 ($38,029.4 net of subsidiary short sale and derivative obligations) at December 31, 2019. The decrease of $594.1 principally reflected net unrealized losses on common stocks, total return swaps, equity warrants and U.S. treasury bond forward contracts, in addition to the specific factors which caused movements in portfolio investments as discussed in the paragraphs that follow.
Subsidiary cash and short term investments (including cash and short term investments pledged for short sale and derivative obligations) decreased by $630.2, primarily reflecting proceeds from sales and maturities of short-dated U.S. treasury bonds principally reinvested into U.S. corporate bonds, partially offset by the reinvestment of U.S. treasury bond proceeds into corporate and other short term investments.
Bonds (including bonds pledged for short sale and derivative obligations) decreased by $808.2 primarily reflecting sales and maturities of short-dated U.S. treasury bonds, partially offset by the reinvestment of proceeds into U.S. corporate bonds.
Common stocks decreased by $772.8 primarily reflecting net unrealized losses as a result of the global economic and social disruption caused by the COVID-19 pandemic."
I am not sure what companies are included in the $772 figure for common stock decrease. But it cannot include Resolute/Atlas/Recipe. Of that $772 figure, I calculate $380 million due to BB, K-W and Stelco losing value from Dec 31 to March 31.
Now, $173 million of that $772 is reversed by the bounce back on BB, K-W and Stelco from March 31 to date. Not including BB converts as I am not sure how those are accounted quarter to quarter.
