calculate_actuarial_pv

Actuarial present value

Actuarial present value engine. Discount expected cash flows with mortality, survival, and risk adjustment for insurance and benefit obligations, generalising IFRS 17 (fulfilment cash flows), IAS 19 (employee benefits), IFRS 2 (share-based payments), and IAS 37 (provisions). Use this for regulated actuarial obligations; for general scenario weighting use calculate_expected_value. Methods: ifrs17_gmm: cash_flows, discount_rate, risk_adjustment; ifrs17_paa: premiums, claims_cash, acquisition_cash_flows, coverage_periods; ifrs17_vfa: cash_flows, discount_rate, underlying_items_return, risk_adjustment; ias19_puc: projected_benefits, discount_rate, attribution_years; ias37_provision: outcomes, probabilities, discount_rate, periods. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising. The result envelope carries status, method, value, assumptions, formula_ref, data_timestamp, steps and error.

calculate_company_summary

Company profile and market inputs

Company-summary engine. Return a company profile with live market metrics (price, shares, beta, volatility, market capitalisation) to seed valuation inputs. Use this to seed inputs for the other calculate_* tools; it does not compute a valuation itself, and it omits missing fields rather than inventing them. Supplying a ticker performs a network fetch Methods: profile: ticker. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising.

calculate_convertible_bond

Convertible and exchangeable bond valuation

Convertible-bond engine. Value callable and puttable convertible or exchangeable bonds with credit risk using a Tsiveriotis-Fernandes lattice (equity discounted at the risk-free rate, debt at a credit spread), with conversion, issuer call, holder put, coupon schedule, and a straight-bond floor. Use this for HK-listed convertible and exchangeable bonds Methods: lattice_tsf/lattice_intensity/finite_difference/lsmc/quantlib: spot, face, coupon_rate, maturity, conversion_ratio, volatility, risk_free, credit_spread, call_schedule, put_schedule, rights_priority. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs.

calculate_credit_loss

Credit loss and impairment

Credit-risk engine (IFRS 9 / HKFRS 9). Compute 12-month, lifetime, and staged expected credit loss, PD/LGD/EAD, provision matrices, hazard rates, and CVA/DVA. Use this for impairment, fair-value credit adjustment, and loan-loss provisioning; for the credit component of a specific convertible bond use calculate_convertible_bond. Methods: ecl_12m: ead, pd, lgd; ecl_lifetime: ead, pd_lifetime, lgd; ecl_staged: ead, pd_12m, pd_lifetime, lgd, stage; provision_matrix: receivables_ageing, loss_rates; pd_from_spread: credit_spread, recovery, tenor_years; cumulative_pd: annual_pd, years; hazard: hazard_rate, tenor_years; cva_dva: exposure_profile, pd, lgd, discount_rate. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising.

calculate_dcf

Discounted cash flow valuation

Discounted cash flow valuation engine. Choose a method and supply its exact inputs to value a business from projected free cash flows, dividends, residual income, or economic profit. Covers FCFF/FCFE DCF, NPV/IRR, terminal values, and multi-stage growth. Use this for going-concern cash-flow businesses; for asset-anchored or financial firms use calculate_residual, for peer-based pricing use calculate_market_multiple, and for pre-profit companies use calculate_loss_making_company. Methods: dcf/npv: cash_flows, discount_rate; annuity: payment, discount_rate, periods; growing_annuity: payment, discount_rate, growth_rate, periods; perpetuity: payment, discount_rate; terminal_gordon: final_cash_flow, discount_rate, perpetual_growth; terminal_multiple: final_cash_flow, exit_multiple; viu_pre_tax: cash_flows, pre_tax_discount_rate; rnpv: cash_flows, discount_rate, probabilities; lease_pv: lease_payments, incremental_borrowing_rate. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising. The result envelope carries status, method, value, assumptions, formula_ref, data_timestamp, steps and error.

calculate_discount_rate

Cost of capital and discount rates

Cost-of-capital engine. Compute WACC, cost of equity (CAPM), cost of debt, unlevered/relevered beta, and country or size premiums from an explicit capital structure and market inputs.

calculate_expected_value

Expected value and probability weighting

Expected-value engine. Compute expected values over discrete, continuous, simulated, or tree-structured uncertainty, plus football-field ranges and discounted provisions. Use this to probability-weight scenarios and ranges inside a valuation; for regulated provisions and insurance or benefit obligations use calculate_actuarial_pv, and for path-dependent payoffs use calculate_structured_product.

calculate_fixed_income

Fixed income and term structure analytics

Fixed-income engine. Price plain coupon bonds, solve for yield to maturity, measure interest-rate sensitivity via Macaulay and modified duration and convexity, and build a HIBOR/HKD-style term structure: bootstrap a zero curve from par rates, infer forward rates, and discount cash flows on the curve. Use this for vanilla bonds, rate risk and discount curves; for convertibles use calculate_convertible_bond and for structured payoffs use calculate_structured_product. Methods: bond_price/duration/convexity: face, coupon_rate, years, ytm, frequency; bond_yield: face, coupon_rate, years, price, frequency; discount_factor: rate, years, frequency; zero_curve: par_rates, tenors, frequency; forward_rate: zero_rates, tenors, t1, t2; pv_curve: cash_flows, times, zero_rates, tenors. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising.

calculate_report_review

Valuation report review and standards audit

Report-review engine. Audit a valuation document against an IVS 2025 and IFRS/HKFRS checklist: methodology, assumptions, discount rate, standards basis, fair-value conclusion, valuation date, and fair-value hierarchy, each mapped to the governing standard. Macro-enabled files are refused Methods: audit: file_path; draft: report_type. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising. The result envelope carries status, method, value, assumptions, formula_ref, data_timestamp, steps and error.

calculate_residual

IFRS measurement, residual income and non-financial fair value

IFRS/HKFRS measurement engine. Compute goodwill and purchase-price allocation, impairment (IAS 36), inventory net realisable value, held-for-sale, debt waterfalls, cap tables, sum-of-the-parts and SPAC redemption; residual income and justified price-to-book; and non-financial asset fair value: investment property (IAS 40 / HKAS 40), PP&E revaluation via depreciated replacement cost (IAS 16) and biological assets at fair value less costs to sell (IAS 41). Use this for accounting-basis measurement of assets and equity; for going-concern cash flow use calculate_dcf and for peer multiples use calculate_market_multiple. Methods: goodwill: purchase_price, fair_value_net_identifiable_assets; ppa: purchase_price, tangible_assets_fv, identified_intangibles_fv; impairment_fvlcd: carrying_value, fair_value_less_costs_to_dispose; impairment_viu: carrying_value, value_in_use; inventory_nrv: carrying_value, net_realisable_value; held_for_sale: carrying_value, fair_value_less_costs_to_sell; debt_waterfall/cap_table: enterprise_value, claims; sotp: segments, net_debt, holding_discount; spac_redemption: trust_cash, shares_outstanding, redemption_price; investment_property: noi, cap_rate; ppe_revaluation: replacement_cost, accumulated_depreciation; biological_asset: expected_price, quantity, costs_to_sell; residual_income: book_value, net_income, cost_equity; justified_pb: roe, cost_equity, growth_rate.

calculate_sector_metrics

Sector-specific operating metrics

Sector-metric engine. Compute the metrics that anchor valuation in specific industries: SaaS (ARR, NRR, magic number, Rule of 40), marketplaces (take rate, GMV multiple), lending (LTV/CAC), and crypto (NVT, Metcalfe). Use these as inputs to a multiple or DCF Methods: ltv: arpu, gross_margin, churn_rate; cac: sales_marketing_expense, new_customers; arr: subscription_values; nrr: starting_revenue, ending_revenue, expansion_revenue; magic_number: net_new_arr, sales_marketing_expense_prior; rule_of_40: growth_rate, profit_margin; take_rate: revenue, gmv; gmv_multiple: gmv, ev_gmv_multiple; retention: retained_customers, starting_customers; trl: market_size, market_share, margin, exit_multiple, trl_discount; break_even: fixed_costs, asp, variable_cost; gross_margin: asp, variable_cost; token: transaction_volume, price_per_tx, velocity, supply; nvt: market_cap, transaction_volume; metcalfe: n, coefficient. Read-only and deterministic: it performs no network I/O (except calculate_company_summary's ticker fetch), mutates no state, and returns the same result for the same inputs. Each method requires its exact inputs (no defaults), so a missing input, an unknown method, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising. The result envelope carries status, method, value, assumptions, formula_ref, data_timestamp, steps and error.
