Because these losses reduced the capital base of LTCM, and its ability to maintain the magnitude of its existing portfolio, LTCM was forced to liquidate a number of its positions at a highly unfavorable moment and suffer further losses. A vivid illustration of the consequences of these forced liquidations is given by Lowenstein (2000). He reports that LTCM established an arbitrage position in the dual-listed company (or "DLC") Royal Dutch Shell in the summer of 1997, when Royal Dutch traded at an 8%–10% premium relative to Shell. In total $2.3 billion was invested, half of which was "long" in Shell and the other half was "short" in Royal Dutch.
