Name	Definition
$MinterGateway \\ index$	The current value of global protocol index used for calculations of $activeOwedM_{minter}$ $MinterGateway\, index_{t1} = fn (index_{t0}, minterRate, t1 - t0)$
$MinterGateway\\ indexLatestUpdateTimestamp$	The last timestamp at which $index$ was updated and stored
$MToken\, index$	The current value of the global $MToken\,index$ used for calculations of $balanceOf_{earner}$ $MToken\; index_{t1} =fn(index_{t0} , earnerRate, t1 - t0)$
$MToken\,indexLatestUpdateTimestamp$	The last timestamp at which$MToken\;index$ was updated and stored
$principalOfActiveOwedM_{minter}$	The principal value of M adjusted to $index_{t}$, where $t$ is the timestamp of minting action: $principalOfActiveOwedM_{minter}, t=mintAmount/index_{t}$
$totalPrincipalOfActiveOwedM$	The total value of $principalOfActiveOwedM$ across all $minters$
$principalOfEarningSupply_{Earner}$	The principal value of M that earns yield for $earner$
$totalPrincipalOfEarningSupply$	The total principal value of M that earns yield for all $earners$
