The collateral is 266.6K mixUSDC, shares in the mixUSDC vault. At a share price of 1.024066 USDC they are worth 273.0K USDC, or $273.0K 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%.

27.2K alUSD of the debt is set aside for repayment. A line redemption clears it, and so does the holder repaying with vault shares or closing the position. At this share price clearing all of it takes 26.5K mixUSDC from the collateral, plus 66.29 mixUSDC for the line’s 0.25% redemption fee.

Across the 61 line redemptions on the timeline below, the line cleared 42.6K alUSD of this position’s debt and took 41,934.756 mixUSDC of its collateral. Valued in USDC at each redemption’s block, with one alUSD counted as one USDC, that is a net of −106.44 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 −106.388 USDC of it (104.575 mixUSDC). Each redemption’s own net is in its card’s detail.
