Explanation

Correct Answer: A - Cash flow problems caused by large mark-to-market losses

Both Metallgesellschaft and LTCM experienced:

Metallgesellschaft (1993):

• Had long-term fixed-price oil delivery contracts
• Hedged with short-term futures contracts
• When oil prices fell, they faced massive margin calls on their futures positions
• Cash flow problems from meeting margin requirements despite having profitable long-term contracts

LTCM (1998):

• Used convergence trading strategies
• When markets moved against them, they faced huge mark-to-market losses
• Required to post additional collateral/margin
• Couldn't meet margin calls due to illiquid positions

Other options analysis:

• B: While LTCM had high leverage, Metallgesellschaft's leverage wasn't the primary issue
• C: Neither case involved fraud as the primary cause
• D: This is incorrect as there are clear similarities in their cash flow problems

Both firms suffered from liquidity crises where they couldn't meet short-term obligations despite potentially profitable long-term positions.
