The collateral is 159.4K mixUSDC, shares in the mixUSDC vault. At a share price of 1.022176 USDC they are worth 162.9K USDC, or $162.9K at USDC’s $1.

A fall of 82.7% in the vault’s share price would take collateralisation from 607.4% to the liquidation line at 105.3%.

2.5K 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 2.4K mixUSDC from the collateral, plus 6.11 mixUSDC for the line’s 0.25% redemption fee.

Across the 56 line redemptions on the timeline below, the line cleared 6K alUSD of this position’s debt and took 5,940.607 mixUSDC of its collateral. Valued in USDC at each redemption’s block, with one alUSD counted as one USDC, that is a net of −14.988 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 −15.051 USDC of it (14.814 mixUSDC). Each redemption’s own net is in its card’s detail.
