Estimated amounts multiply the change in shares by the quarter-end price implied by the filing (market value divided by shares): new positions use this quarter's value and sold-out positions last quarter's; positions reported only as principal (PRN) cannot be estimated. 13F shows only quarter-end holdings, not when trades happened or at what price.
