+## Simple Summary
+
+A proposal for further deprecation recommendations on Aave AMM v2. For more details, see the full forum post [here](https://governance.aave.com/t/arfc-deprecate-aave-v2-amm-market-step-2/16408/2).
+
+## Motivation
+
+Gauntlet aims to reduce the remaining $94k borrow position and migrate users off the AMM market. Further analysis and information can be found in our forum [post](https://governance.aave.com/t/arfc-deprecate-aave-v2-amm-market-step-2/16408).
+
+## Specification
+
+Gauntlet recommends to increase reserve factor to 99% for the following assets:
+
+| Asset | Current RF | Recommended RF |
+| ----- | ---------- | -------------- |
+| WETH  | 0.1        | 0.99           |
+| DAI   | 0.1        | 0.99           |
+| USDC  | 0.1        | 0.99           |
+| WBTC  | 0.2        | 0.99           |
+| USDT  | 0.1        | 0.99           |
+
+Gauntlet recommends to adjust the IR params for the following assets:
+| Asset | Current Variable Base | Recommended Variable Base | Current Variable Slope1 | Recommended Variable Slope1 |
+| ----- | --------------------- | ------------------------- | ----------------------- | --------------------------- |
+| WETH | 0 | 0.06 | 0.08 | No Change |
+| DAI | 0 | 0.04 | 0.04 | 0.1 |
+| USDC | 0 | 0.04 | 0.04 | 0.1 |
+| WBTC | 0 | 0.05 | 0.08 | No Change |
+| USDT | 0 | 0.06 | 0.04 | 0.1 |
