(iv)the sum of: (a) the alternate rate of interest that has been selected by the Lender as the replacement for the then-

(iii)“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(ii)a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

(iii)a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

(iv)Term SOFR Administrator” means CME Group Benchmark Administration Limited as administrator of the forward-looking term SOFR (or a successor administrator).
