  "canonical_statement": "For an unkilled Levy process $\\xi$ drifting to $+\\infty$ with all positive exponential moments, let $I_\\xi = \\int_0^\\infty e^{-\\xi_t}\\,dt$ and $X_\\xi = 1/I_\\xi$. Bertoin and Yor proved $X_\\xi$ is moment-determinate when $\\xi$ has no positive jumps and conjectured that this condition is necessary. The conjecture is settled.",
