In risk theory <jats:italic>R<\/jats:italic>\n               <jats:sub>\u03b3<\/jats:sub>(<jats:italic>u<\/jats:italic>) = <jats:italic>u<\/jats:italic> - <jats:italic>W<\/jats:italic>\n               <jats:sub>\u03b3<\/jats:sub>(<jats:italic>t<\/jats:italic>), <jats:italic>t<\/jats:italic> \u2265 0, is referred to as the risk process with tax payments of a loss-carry-forward type. For various risk processes, numerous results are known for the approximation of the first and last passage times to 0 (ruin times) when the initial reserve <jats:italic>u<\/jats:italic> goes to \u221e. In this paper we show that, for the \u03b3-reflected process, the conditional (standardized) first and last passage times are jointly asymptotically Gaussian and completely dependent.
