For Nissan Motor Co. finance chief Stephen Ma, the weak yen has been both a boon and a bane. “The current weakness of the yen has given us short-term benefits, which is good,” Mr. Ma said. Mr. Ma said he is working to repay debt and increase the auto maker’s profitability while managing issues such as currency volatility, semiconductor shortages and pricing. “We have some stickiness in terms of pricing power,” Mr. Ma said. Nissan has had “common sense, commercial-based” discussions with Renault, according to Mr. Ma.
