Problem: Categorize trades in a bank´s portfolio

A bank has a portfolio of thousands of trades and they need to be categorized. A trade is a commercial negotiation between a bank and a client. A trade has many characteristics, including:

interface ITrade

{
...
double Value { get; } //indicates the transaction amount in dollars
string ClientSector { get; } //indicates the client´s sector which can be "Public" or "Private"
DateTime NextPaymentDate { get; } //indicates when the next payment from the client to the bank is expected
...
}

Currently, there are three categories (in order of precedence):

1. EXPIRED: Trades whose next payment date is late by more than 30 days based on a reference date which will be given.
2. HIGHRISK: Trades with value greater than 1,000,000 and client from Private Sector.
3. MEDIUMRISK: Trades with value greater than 1,000,000 and client from Public Sector.

Write a C# console application using object oriented design that classifies all trades in a given portfolio. Keep in mind that the real application may have dozens of categories, so your design must be extensible allowing those categories to be easily added/removed/modified in the future. The code can be sent in a GitHub link

Input
The first line of the input is the reference date. The second line contains an integer n, the number of trades in the portfolio. The next n lines contain 3 elements each (separated by a space). First a double that represents trade amount, second a string that represents the client’s sector and third a date that represents the next pending payment. All dates are in the format mm/dd/yyyy.

Output
N lines with the category of each one of the n trades.
