B.
Bus operator Barkway has been hit by stiff competition and dwindling profitability. As a result the company has been forced to scrap its plans to expand overseas and instead will concentrate on growing its existing business. The continuing decline in the company's share price has led to speculation that it may fall prey to one of its rivals.

C.
Carolyn Swaine, the former chief executive of coffee shop chain Marshmont's, is trying hard to raise capital for a bid for her old company. Swaine left last year after a series of disagreements over Marshmont's future direction, and several top managers are expected to leave if she succeeds in buying the chain. Although Marshmont's is profitable, it is too small to stay independent for much longer, and even if Swaine takes control, the company will soon have to become part of a larger chain.
D.
Keston, the respected maker of television programmes, has announced that it has agreed an outline deal to merge with Stardust TV. A year ago, with its profits plunging, Keston faced a strong takeover bid by another of its competitors, but fought hard against it, and has since become more profitable. The company is now convinced, however, that its future success lies in being part of a larger organisation. Both Keston and Stardust have a reputation for producing striking television programmes, and a merger is likely to be beneficial, both creatively and financially. This company has changed its attitude towards remaining independent.
