While I can't speak to the exact circumstances, IBM when it takes over operations often hires the IT staff of the firm it is taking over operations from and runs systems on multiple-year contracts.
At any rate, I believe few would contest that IBM in general is a more reliable vendor than Tata, other Indian suppliers or say, offices in Poland.
