Abstract
Since 2018, banks have implemented the expected credit loss (ECL) model under International Financial Reporting Standard (IFRS) 9 to estimate loan losses, which replaces the incurred loss model under International Accounting Standard (IAS) 39. The key novelty of the ECL model is the incorporation of forward-looking information for recognizing accounting loan loss provisions (LLPs), which provides ample room for managerial discretion. Over the period 2014–2019, I first show that the shift to the ECL model improves the timeliness of loan loss recognition. However, under the IFRS 9 regime managers also use their accounting discretion more aggressively over LLP estimates to smooth earnings. I then investigate whether IFRS 9 improves the relevance of LLPs for credit default swap (CDS) pricing. I report that LLPs under IFRS 9 are incrementally more relevant than under IAS 39 for CDS pricing but mostly concentrated amongst banks with weaker pre-IFRS 9 information environments. I further show that under the IFRS 9 regime, LLPs are relevant for CDS pricing only when LLPs consistently reflect future expected losses while earnings smoothing via LLP generally impair the credit-risk relevance of LLPs. Finally, I find that strong governance is imperative for providing useful LLP estimates for CDS pricing.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
