2001: NAB sold HomeSide’s operating assets for US$1.9b to Washington Mutual, the largest US savings and loan company, as well as the mortgage unit's loan-servicing technology and operating platform. NAB booked two write-downs associated with the US subsidiary, HomeSide. First, in July 2001, NAB had a $450 million write down of the value of its capitalized mortgage servicing rights (CMSRs) during the quarter ending June 30, 2001, and was the result of exceptionally high mortgage refinance volumes which lowered the value of the CMSRs, combined with a more challenging capital markets environment in which to hedge interest rate risk. This was followed shortly by a second write-down reported in September totalling $1.75 billion; this second write-down consisted of US$400 million from an incorrect interest rate assumption embedded in the mortgage servicing rights valuation model, US$760 million from changed assumptions in the model flowing from the continued unprecedented uncertainty and turbulence in the mortgage servicing market, and US$590 million from writing off of the goodwill. In total, NAB booked $2.2 billion in losses due to HomeSide.
