Nippon Life Insurance Co. records its first impairment loss on Japanese government bonds, indicating that losses on some of its holdings have risen to levels that require writedowns. Bloomberg reports the insurer books the impairment loss during the current bond rout, reflecting that unrealized losses have moved into impairment territory. The Japan Times adds that Nippon Life records a ¥70 billion impairment loss in the fiscal year ended March 31.

The impairment reflects accounting treatment under which certain losses on bond portfolios are recognized when declines are assessed as not temporary. The reports characterize the action as the company’s first such writedown for its Japanese government bond holdings, rather than a general change in valuation for the entire portfolio.

Together, the outlets indicate that Nippon Life’s exposure to yen government bonds leads to the first impairment recognition amid market losses, with the recorded amount cited as ¥70 billion for the year ended March 31.
