So far this month, PacWest shares have lost nearly 40%. During the week ended May 5, deposits declined about 9.5%, the bank said, adding the majority of those outflows happened on May 4 and May 5 after news reports said PacWest was exploring options. But at the end of the first quarter, PacWest had $341.7 million in cash and cash equivalents, which it said would be sufficient to fund cash flow needs over the next 12 months.
