The head of the structured securities desk at an investment bank directs all derivatives traders on the desk to use trade compressions on all eligible trades to reduce counterparty risk. One of the analysts decides to use trade compression on a portfolio of single-name CDS contracts with the same maturity and transacted with two counterparties, as presented in the table below, to estimate the investment bank's compressed notional value:

| Counterparty | Reference credit | Notional (EUR million) | Bank's position | Coupon (bps) |

|-----------------------|--------------------|------------------------|---------------------|--------------|

| Digital Corporation | NUMU Inc. | 9 | Long protection | 180 |

| Digital Corporation | WKL Company | 6 | Long protection | 150 |

| WKL Company | NUMU Inc. | 7 | Short protection | 150 |

What is the notional value of the investment bank's net contract on compressed trades only?
