Charter Communications ( CHTR) can't seem to turn the corner.The nation's third-largest publicly traded operator of cable TV systems said Tuesday that CEO Carl Vogel resigned. Robert May, currently a Charter board member and the chairman of HealthSouth, will run Charter until a replacement can be found. The appointment of May -- who navigated HealthSouth away from financial disaster after CEO Richard Scrushy was sucked into the company's accounting scandal -- appears to be a succor for Charter, which has suffered its own number-crunching scandal and brush with bankruptcy. But a conference call with analysts Tuesday -- during which May spoke often about the company's new strategy of focusing on its customers' satisfaction -- forced one to wonder why the company is so late in addressing the issue of making its customers happier. After all, it is not as if Charter had no clue that customers, in the aggregate, haven't been quite happy with the service. In recent years, customer counts have been falling significantly. More likely, worries about liquidity, including Charter's efforts over the past year to refinance intimidating debt, have taken Charter management's focus away from actually running a business that people want to pay money for. Though that explanation is perfectly understandable, given Charter's financial travails, it has to be truly frightening, from a shareholder's point of view, to hear an executive at a company with 6.1 million customers talk about how the company needs to pay more attention to its customers. Charter's shares fell 8 cents Tuesday to trade at $1.97. The company's shares traded north of $24 in 2001, but fell to as low as 76 cents in March 2003, in the wake of disappointing quarterly results and news of investigations of how the company counted its customers and accounted for certain costs.
