The collateral is 1.4M mixUSDC, shares in the mixUSDC vault. At a share price of 1.0209 USDC they are worth 1.4M USDC, or $1.4M at USDC’s $1.

A fall of 5.3% in the vault’s share price would take collateralisation from 111.1% to the liquidation line at 105.3%.

149.3K alUSD of the debt is set aside for repayment. Line redemptions clear it, and at this share price clearing all of it takes 146.2K mixUSDC from the collateral, plus 365.53 mixUSDC for the line’s 0.25% redemption fee.

Across the 51 line redemptions on the timeline below, the line cleared 345.6K alUSD of this position’s debt and took 341,113.453 mixUSDC of its collateral. Valued in USDC at each redemption’s block, with one alUSD counted as one USDC, that is a net of −863.807 USDC for the holder: the debt cleared less the value of the collateral taken. The line’s 0.25% redemption fee, paid to Alchemix’s fee receiver, is −863.986 USDC of it (850.657 mixUSDC). Each redemption’s own net is in its card’s detail.

Set-aside grows block by block between readings, and an event card’s before figure is the reading at the previous card’s block, so a card’s set-aside move includes what built up in between.
