The current PCA Framework was revised in which year?

Read the following passage and answer the next 5 question Central Bank along with a clutch of other lenders was placed under RBI's prompt corrective action (PCA) in 2017 after the regulator found some state-run lenders were in breach of its rules on regulatory capital, bad loans and leverage ratios. Since then all the lenders except Central Bank have improved their financial health and come off RBI's PCA list. A bank under PCA faces greater scrutiny by the regulator and may face lending and deposit restrictions, branch expansion and hiring freezes and other limitations on borrowings. The RBI introduced these norms at a time when Indian lenders were battling record levels of soured assets, prompting the RBI to tighten thresholds. Source: economictimes
