Moody\u2019s Corp.\u2019s India unit is investigating a whistle-blower complaint that executives at the ratings company interfered to guarantee top AAA ratings for a financier that plunged to default just two months later. ICRA Ltd. is probing certain matters related to a debt rating it assigned to a client and its subsidiaries, the company disclosed Thursday in an earnings statement, without naming the client. ET Now television channel reported that the complaint says ICRA executives meddled to ensure Infrastructure Leasing & Financial Services Ltd. would receive an AAA rating, citing people it didn\u2019t identify. The New Delhi-based unit of Moody\u2019s said in the statement it has hired external experts to help with the issue. A representative for Moody\u2019s in New York said the company declined to comment. IL&FS came under government control last year after it amassed huge debts tied to a failed foray into project development and defaulted on multiple obligations. The company had been arranging financing for Indian infrastructure projects for more than 30 years and was considered \u201csystemically important\u201d by the country\u2019s central bank. The Indian government made its second-ever takeover of a company when investors fretted that its failure could have repercussions for the wider economy. Credit raters like ICRA have come under fire for missing warning signs like the financier\u2019s surging debt load, which jumped 44 percent between 2015 and 2018. The conglomerate had nearly 348 entities and complex finances to match. IL&FS\u2019s bonds and loans held AAA ratings until August 2018, when the grade was cut to AA+, the second-highest rank. A month later, a unit of the company defaulted on short-term debt obligations. ICRA hit the company with a 10-notch downgrade to BB, a junk grade. The ratings firm cited the company\u2019s \u201cincrease in liquidity pressure\u201d amid \u201csizable repayment obligations.\u201d The company was cut yet again to D, a rating reserved for debt in default or expected to be in default in a matter of days. IL&FS Long-Term Rating Effective Date AAA July 31, 2006 AA+ August 6, 2018 BB September 8, 2018 D September 17, 2018 ICRA has earmarked money that could go toward a fine or settlement even though no findings have emerged yet from the investigation, it said in the statement. It set aside an additional 20 million rupees ($288,614) in the quarter that ended March 31 compared with a year earlier.
